技术领域technical field
本发明涉及能够使投影设备的投射光折射的多投影系统，并且(更具体地)涉及其中组成多投影系统的所有或者一些投影设备以能够折射投射光的方式进行配置的多投影系统。The present invention relates to a multi-projection system capable of refracting projection light of projection devices, and more particularly, to a multi-projection system in which all or some of the projection devices constituting the multi-projection system are configured in such a manner that projection light can be refracted.
背景技术Background technique
照惯例，为了重现诸如电影、广告等的图像，二维图像被投射在布置在剧场前方的单个屏幕上。然而，在这样的系统下观众只能观看二维(2D)图像。Conventionally, in order to reproduce images such as movies, advertisements, etc., two-dimensional images are projected on a single screen arranged in front of a theater. However, viewers can only view two-dimensional (2D) images under such systems.
近来已开发了用于提供给观众三维图像的三维(3D)图像技术。3D图像技术使用了当不同的图像出现在观众的左眼和右眼中并在大脑中合成时使观众即使在平面图像中也能够感觉到3D效果的原理。具体地，在拍摄过程中使用两台配备有不同的偏振滤波器的摄像机，并且观众佩戴具有偏振滤波器的眼镜，以使得在观看期间在左眼和右眼中出现不同的图像。Three-dimensional (3D) image technologies for providing three-dimensional images to viewers have recently been developed. The 3D image technology uses the principle that the viewer can feel a 3D effect even in a flat image when different images appear in the viewer's left and right eyes and are synthesized in the brain. Specifically, two cameras equipped with different polarization filters are used during filming, and viewers wear glasses with polarization filters so that different images appear in left and right eyes during viewing.
然而，尽管这些3D技术能够将3D图像提供给观众，但是观众只是观看重现在单个屏幕上的图像，这可能降低图像中的参与度。此外，观众感觉到的3D效果的方向受限于单个屏幕的方向。However, although these 3D technologies can provide 3D images to viewers, the viewers only watch the images reproduced on a single screen, which may reduce the degree of participation in the images. In addition, the direction of the 3D effect perceived by the viewer is limited by the direction of a single screen.
此外，根据传统的3D技术，观众在观看期间必须佩带配备有偏振滤波器的眼镜，这可能使观众感觉不便，不同的图像人为地出现在左眼和右眼中，这可能使一些观众感觉到头晕或恶心。In addition, according to the conventional 3D technology, viewers have to wear glasses equipped with polarization filters during viewing, which may cause inconvenience to viewers, and different images artificially appear in left and right eyes, which may make some viewers feel dizzy or disgusting.
因此，已经提出了能够解决基于单屏幕的传统投射系统的这些问题的所谓的“多投影系统”。该“多投影系统”指的是其中多个投影面围绕观众席布置以使得在该多个投影面上重现同步图像的技术，从而向观众提供三维效果以及沉浸感。Therefore, so-called "multi-projection systems" have been proposed which can solve these problems of conventional projection systems based on a single screen. The "multi-projection system" refers to a technology in which a plurality of projection surfaces are arranged around auditoriums so that synchronized images are reproduced on the plurality of projection surfaces, thereby providing audiences with a three-dimensional effect and a sense of immersion.
此外，为了实现该“多投影系统”，必须围绕观众席布置“多个投影面”并且安装用于将图像投射在该多个投影面上的“两个或更多个投影设备”。在这种情况下，当投影面和投影设备如在典型投影系统(即，具有单个投影面的投影系统)中彼此面对安装时，可能出现各种问题(也就是说，当“多个投影面”和“两个或更多个投影设备”彼此面对安装时，可能出现各种问题)。Furthermore, in order to realize this "multi-projection system", it is necessary to arrange "a plurality of projection surfaces" around the auditorium and install "two or more projection devices" for projecting images on the plurality of projection surfaces. In this case, when the projection surface and the projection device are installed facing each other as in a typical projection system (ie, a projection system with a single projection surface), various problems may arise (that is, when "multiple projections Various problems may arise when installing "side" and "two or more projection devices" facing each other).
例如，安装成面对多个投影面的两个或更多个投影设备可能在观众的可视范围内以复杂的方式进行布置，因此这可能会降低观众的沉浸感。For example, two or more projection devices installed to face multiple projection surfaces may be arranged in a complex manner within the viewer's visual range, and thus this may reduce the immersion of the viewer.
此外，安装成彼此面对的面对投影面(例如，左投影面和右投影面、前投影面和后投影面等)的投影设备可能会干扰它们的投射操作。Furthermore, projection devices installed to face each other facing projection surfaces (for example, left and right projection surfaces, front and rear projection surfaces, etc.) may interfere with their projection operations.
此外，当两个或更多个投影设备被安装成面对多个投影面时，由于很难确保安装空间，某些投影设备应当被安装在地板上，因此安装在地板上的投影设备具有引发安全事故的风险。也就是说，由于剧场太暗，观众可能被安装在地板上的投影设备绊倒。In addition, when two or more projection devices are installed to face a plurality of projection surfaces, since it is difficult to secure an installation space, some projection devices should be installed on the floor, so the projection devices installed on the floor have Risk of security incidents. That said, audiences could trip over floor-mounted projection equipment because the theater is so dark.
因此，需要开发一种能够解决这些问题的新的“多投影系统”。Therefore, there is a need to develop a new "multi-projection system" capable of solving these problems.

有益效果Beneficial effect
本发明能够使由投影设备所投射的投射光折射，然后使经折射的投射光能够到达投影面。因此，即使当投影面和投影设备不彼此面对地进行安装时投影设备的投射光也能够到达投影面。The present invention can refract the projection light projected by the projection device, and then allow the refracted projection light to reach the projection surface. Therefore, projection light of the projection device can reach the projection surface even when the projection surface and the projection device are installed not facing each other.
此外，本发明能够以不同的角度使单个投影设备的投射光折射。因此，本发明可以使单个投影设备能够选择性地将图像投射在多个投影面上。例如，本发明能够使单个投影设备的投射光折射，以使得图像能够被重现在投影面A、B或C上，或者包括在多个投影面中的不同的投影面上。Furthermore, the present invention can refract the projected light of a single projection device at different angles. Therefore, the present invention can enable a single projection device to selectively project images on multiple projection surfaces. For example, the present invention can refract projected light of a single projection device so that an image can be reproduced on projection plane A, B, or C, or included on a different one of a plurality of projection planes.
此外，本发明可将用于将图像投射在多个投影面上的两个或更多个投影设备一起安装在剧场的特定空间中。具体地说，本发明可将两个或更多个投影设备一起安装在观众的视野之外的空间中(例如，观众席的后面)，然后使各个投影设备的投射光折射以使图像能够到达多个投影面上。因此，能够在不降低观众的沉浸感并且不干扰相应的投影面的情况下将图像投射在布置在单个剧场中的多个投影面上。In addition, the present invention can install two or more projection devices for projecting images on a plurality of projection surfaces together in a specific space of a theater. Specifically, the present invention can install two or more projection devices together in a space out of view of the audience (for example, behind the auditorium), and then refract the projected light of each projection device so that the image can reach Multiple projection surfaces. Therefore, it is possible to project images on a plurality of projection surfaces arranged in a single theater without degrading the audience's sense of immersion and without disturbing the corresponding projection surfaces.
另外，本发明可安装比覆盖布置在剧场中的投影面所需的投影设备的数量更多的投影设备(其中投射光可被折射)。此外，本发明可在各个放映期间分析投影设备的性能信息(例如，亮度信息、分辨率信息、维护信息等)，然后选择并使用具有出色性能的投影设备。因此，可确保用于投射图像的投影设备的性能，并因此可确保被投射的图像的质量。此外，具有性能问题的投影设备可被自动去除，并因此即使在特定的投影设备出现故障时该多投影系统也可以正常操作。In addition, the present invention can install a larger number of projection devices (in which projected light can be refracted) than is required to cover a projection surface arranged in a theater. In addition, the present invention can analyze performance information (eg, brightness information, resolution information, maintenance information, etc.) of projection devices during each showing, and then select and use a projection device with excellent performance. Accordingly, the performance of a projection device for projecting an image, and thus the quality of a projected image can be ensured. In addition, projection devices having performance problems can be automatically removed, and thus the multi-projection system can operate normally even when a particular projection device fails.
此外，本发明可使辅投影设备能够在主投影设备发生故障时替代该主投影设备。具体地，倘若主投影设备出现故障，本发明可将主图像发送到辅投影设备，以使得该辅投影设备投射该主图像，并且将辅投影设备的投射光折射到主投影面上，从而使辅投影设备能够替代该主投影设备。Furthermore, the present invention enables a secondary projection device to replace the primary projection device in the event of a failure of the primary projection device. Specifically, if the main projection device breaks down, the present invention can send the main image to the auxiliary projection device, so that the auxiliary projection device projects the main image, and refracts the projection light of the auxiliary projection device onto the main projection surface, so that A secondary projection device can replace the primary projection device.
而且，本发明可分析各个辅投影设备的性能信息，以选择将替代主投影设备的辅投影设备，并且使所选择的被确定具有最佳性能的辅投影设备能够替代主投影设备。因此，即使在主投影设备发生故障时也能够投射最佳质量的图像。Also, the present invention may analyze performance information of each auxiliary projection device to select an auxiliary projection device that will replace the main projection device, and enable the selected auxiliary projection device determined to have the best performance to replace the main projection device. Therefore, the best quality images can be projected even when the main projection equipment fails.

具体实施方式detailed description
在下文中，将结合附图对根据本发明的“能够折射投影设备的投射光的多投影系统”进行更加详细的描述。提供下列实施方式仅用于例示性的目的，以便本领域的技术人员可充分理解本发明的精神，但是本发明并不限于此。此外，应当理解的是，本文在附图中所阐明的所有问题将都被解释为例示性的，并且可以是以与实际实现的形式不同的形式。Hereinafter, the "multi-projection system capable of refracting projected light of a projection device" according to the present invention will be described in more detail with reference to the accompanying drawings. The following embodiments are provided for illustrative purposes only so that those skilled in the art can fully understand the spirit of the present invention, but the present invention is not limited thereto. Furthermore, it should be understood that all matters set forth herein in the drawings are to be interpreted as illustrative and may be in a form different from that of actual realization.
下面将要描述的本发明与上文所提到的“多投影系统”有关。The present invention to be described below relates to the "multi-projection system" mentioned above.
因此，现在将简略地描述作为本发明的基础的“多投影系统”，并随后将更加详细地描述本发明的特征。Therefore, the "multi-projection system" on which the present invention is based will now be briefly described, and then features of the present invention will be described in more detail.
随后，将参照图1至图4对作为本发明的基础的“多投影系统”进行描述。Subsequently, a "multi-projection system" which is the basis of the present invention will be described with reference to FIGS. 1 to 4 .
作为本发明的基础的多投影系统指的是可以将同步的图像提供到安装在单个剧场中的多个投影面上并且最大化真实感、三维效果以及观众可以感觉身处这些环境当中的沉浸感的系统。也就是说，多投影系统指的是其中在单个剧场中设置多个投影面以将该多个投影面上的同步图像提供给观众的系统。The multi-projection system that is the basis of the present invention refers to the ability to provide synchronized images to multiple projection surfaces installed in a single theater and maximize the realism, three-dimensional effect and immersion that the audience can feel in these environments system. That is, the multi-projection system refers to a system in which a plurality of projection surfaces are provided in a single theater to provide synchronized images on the plurality of projection surfaces to audiences.
多个投影面被提供用于单个剧场中的多投射。多个图像可被重现在多个投影面上。此处，优选的是，重现在多个投影面上的图像彼此同步并且综合地创建一个统一的图像。也就是说，虽然不同的图像可被重现在相应的投影面上，但优选的是，当观看整个投影面时，这些不同的图像彼此同步并且创建一个统一的图像。此外，根据不同的情况，单独的图像可被重现在每一个投影面上或者图像可被只重现在某些投影面上。Multiple projection surfaces are provided for multi-projection in a single theater. Multiple images can be reproduced on multiple projection surfaces. Here, it is preferable that the images reproduced on the plurality of projection surfaces are synchronized with each other and comprehensively create one unified image. That is, although different images may be reproduced on respective projection surfaces, it is preferable that these different images are synchronized with each other and create one unified image when viewing the entire projection surface. Furthermore, a separate image may be reproduced on each projection surface or images may be reproduced only on some projection surfaces, depending on circumstances.
此外，多个投影面可使用全部的多个投影面或者只使用多个投影面中的一些来重现图像。例如，多个投影面可提供下列状态：其中图像仅被重现在具体的投影面上的状态(状态1)；其中图像仅被重现在多个投影面中的一些上的状态(状态2)；以及其中图像被重现在全部多个投影面上的状态(状态3)，并且这些状态1至状态3可在图像内容投射期间交替地实现。In addition, the multiple projection surfaces may use all of the multiple projection surfaces or only some of the multiple projection surfaces to reproduce an image. For example, multiple projection surfaces may provide the following states: a state in which the image is only rendered on a specific projection surface (state 1); a state in which the image is only reproduced on some of the plurality of projection surfaces (state 2); And a state (state 3) in which an image is reproduced on all of the plurality of projection surfaces, and these state 1 to state 3 can be alternately realized during image content projection.
而且，多个投影面可被彼此不平行地布置。根据现有技术，图像只被投射在置于剧场前方的屏幕上，以使得观众观看重现在二维屏幕上的图像，或者3D技术被应用到重现在平面上的图像本身。相反，在作为本发明的基础的多投影系统中，多个投影面被三维地布置以使其彼此不平行，并因此能够通过三维地布置的多个投影面将具有高3D效果和沉浸感的三维图像提供给观众，而无需将3D技术应用到图像本身。Also, a plurality of projection planes may be arranged non-parallel to each other. According to the prior art, images are projected only on a screen placed in front of a theater so that audiences watch images reproduced on a two-dimensional screen, or 3D technology is applied to the images themselves reproduced on a flat surface. On the contrary, in the multi-projection system which is the basis of the present invention, a plurality of projection surfaces are three-dimensionally arranged so as not to be parallel to each other, and thus it is possible to have a high 3D effect and a sense of immersion through the three-dimensionally arranged plurality of projection surfaces. A three-dimensional image is provided to the viewer without applying 3D technology to the image itself.
此外，优选的是，多个投影面被彼此不平行地布置并且被布置成围绕剧场中的观众席。因此，观众能够感觉犹如他们处于由重现在多个投影面上的同步的图像所创造出来的空间中，并因此观众所感觉到的三维效果、沉浸感以及虚拟现实感可被最大化。Furthermore, it is preferable that the plurality of projection surfaces are arranged non-parallel to each other and arranged to surround an auditorium in a theater. Accordingly, viewers can feel as if they are in a space created by synchronized images reproduced on a plurality of projection surfaces, and thus the three-dimensional effect, immersion, and virtual reality sensed by the viewers can be maximized.
另外，投影面之间的角度不限于特定的角度，并且只要观众能够感觉到三维效果，能够以各种角度来布置多个投影面。In addition, the angle between the projection surfaces is not limited to a specific angle, and a plurality of projection surfaces can be arranged at various angles as long as the viewer can feel a three-dimensional effect.
此外，多个投影面可被布置成彼此毗邻或者布置成彼此相间隔，即使在这种情况下，优选的是，多个投影面也要布置成围绕观众席。Furthermore, a plurality of projection surfaces may be arranged adjacent to each other or arranged to be spaced apart from each other, and even in this case, it is preferable that the plurality of projection surfaces are arranged to surround the auditorium.
图1示出了其中多个投影面被布置在相对于观众席的前方、左侧和右侧的示例，图2示出了其中多个投影面被布置在相对于观众席的前方、左侧、右侧和上侧(天花板)的示例，图3示出了其中多个投影面被布置在相对于观众席的前方、左侧、右侧、上侧(天花板)和下侧(地板)的示例。FIG. 1 shows an example in which a plurality of projection surfaces are arranged on the front, left and right sides with respect to the auditorium, and FIG. 2 shows an example in which a plurality of projection surfaces are arranged on the front, left side with respect to the auditorium. , right side and upper side (ceiling), Fig. 3 shows an example in which a plurality of projection surfaces are arranged in the front, left side, right side, upper side (ceiling) and lower side (floor) with respect to auditorium example.
此外，参照图4，多投影系统可以进一步包括两个或更多个用于将图像投射在多个投影面上的投影设备300，并且还可以进一步包括用于控制该两个或更多个投影设备300的操作的管理设备400。In addition, referring to FIG. 4, the multi-projection system may further include two or more projection devices 300 for projecting images on multiple projection surfaces, and may further include a device for controlling the two or more projection devices 300. The operation of the device 300 is managed by the device 400 .
两个或更多个投影设备300被配置成将图像投射在上述多个投影面上。该两个或更多个投影设备300能够以各种方式通过包括光学系统和加热单元来实现。例如，投影设备300能够以诸如通过使用阴极射线管(CRT)、使用液晶显示器(LCD)、通过使用数字微镜器件(DMD)芯片的数字光处理(DLP)、通过硅上液晶(LCoS)等的各种方式来实现。此外，投影设备300能够以除这些方式外的各种方式来实现。Two or more projection devices 300 are configured to project images on the aforementioned plurality of projection surfaces. The two or more projection apparatuses 300 can be implemented in various ways by including an optical system and a heating unit. For example, the projection device 300 can be configured in a manner such as by using a cathode ray tube (CRT), using a liquid crystal display (LCD), by using digital light processing (DLP) using a digital micromirror device (DMD) chip, by using liquid crystal on silicon (LCoS), etc. various ways to achieve. In addition, the projection apparatus 300 can be realized in various ways other than these ways.
管理设备400被配置为控制两个或更多个投影设备300。管理设备400可并联连接到两个或更多个投影设备300，以便通过此并联连接同时地或者单独地控制相应的投影设备300。此外，该管理设备400可整体管理由两个或更多个投影设备300所投射的图像，并且如有必要可校正由两个或更多个投影设备300所投射的图像。此外，管理设备400可整体控制包括在多投影系统中的各种设备的操作以及两个或更多个投影设备300的操作。The management device 400 is configured to control two or more projection devices 300 . The management device 400 may be connected to two or more projection devices 300 in parallel so as to simultaneously or individually control the corresponding projection devices 300 through the parallel connection. Furthermore, the management device 400 can manage images projected by two or more projection devices 300 as a whole, and can correct the images projected by two or more projection devices 300 if necessary. Also, the management device 400 may collectively control operations of various devices included in the multi-projection system and operations of two or more projection devices 300 .
管理设备400可利用各种电子设备来实现。管理设备400可利用单个的电子设备或者利用多个彼此互连的电子设备来实现。例如，管理设备400可在单个服务器中或者以两个或更多个服务器互连的方式来实现。此外，管理设备400可以用一个服务器与其它电子设备互连的方式实现或者在除服务器之外的其它运算单元中实现。The management device 400 can be implemented using various electronic devices. The management device 400 can be implemented by using a single electronic device or by using multiple interconnected electronic devices. For example, the management device 400 can be implemented in a single server or in a manner of interconnecting two or more servers. In addition, the management device 400 may be implemented in a manner of interconnecting a server with other electronic devices or implemented in other computing units other than the server.
此外，管理设备400可利用分级连接的多个服务器来实现。例如，管理设备400可以用单个主服务器和多个从服务器彼此相连接的方式来实现。在这种情况下，多个从服务器分别控制安装在多投影系统中的设备(例如，从服务器1控制投影设备A至投影设备D，从服务器1控制投影设备E至投影设备H，等)，并且单个主服务器通常控制多个从服务器的操作。Also, the management device 400 can be implemented using a plurality of servers connected hierarchically. For example, the management device 400 can be implemented in a manner that a single master server and multiple slave servers are connected to each other. In this case, a plurality of slave servers respectively control devices installed in the multi-projection system (for example, from server 1 to control projection device A to projection device D, from server 1 to control projection device E to projection device H, etc.), And a single master usually controls the operation of multiple slaves.
此外，组成多投影系统的多个投影面可以用诸如屏幕、内部结构表面(例如，地板、墙壁、天花板等)等的各种形式进行配置。In addition, multiple projection surfaces constituting a multi-projection system may be configured in various forms such as screens, internal structural surfaces (eg, floors, walls, ceilings, etc.) and the like.
此外，多个投影面可包括相同类型的投影面，但是也可优选地包括不同类型的投影面。例如，多个投影面可包括(i)不同类型的屏幕、(ii)不同类型的内部结构表面、(iii)不同类型的屏幕和内部结构表面等。Furthermore, the plurality of projection surfaces may comprise the same type of projection surfaces, but may preferably also comprise different types of projection surfaces. For example, multiple projection surfaces may include (i) different types of screens, (ii) different types of internal structural surfaces, (iii) different types of screens and internal structural surfaces, and the like.
然而，当利用这些不同类型的投影面配置多个投影面时，在重现到该多个投影面上的图像之间可能出现不均匀性。具体地，组成多个投影面的各个投影面具有不同的属性，并因此在重现到各个投影面上的图像之间可能出现不均匀性。因此，去除图像之间的不均匀性是必要的，因为该不均匀性可能降低观众在图像中的沉浸感和三维效果。However, when a plurality of projection surfaces are configured using these different types of projection surfaces, non-uniformity may occur between images reproduced on the plurality of projection surfaces. Specifically, respective projection surfaces constituting a plurality of projection surfaces have different attributes, and thus non-uniformity may occur between images reproduced onto the respective projection surfaces. Therefore, it is necessary to remove inhomogeneities between images, which may reduce the immersion and three-dimensional effect of the viewer in the images.
本发明可基于投影面之间的属性的差异执行图像校正，并且该图像校正可改善重现到多个投影面上的图像的不均匀性。The present invention can perform image correction based on a difference in properties between projection surfaces, and the image correction can improve unevenness of images reproduced on a plurality of projection surfaces.
现在将详细描述图像校正。图像校正可包括下列步骤：(1)分析投影面之间的属性的差异；以及(2)执行图像校正以便基于所分析的关于投影面之间的属性的差异的信息补偿属性的差异。Image correction will now be described in detail. The image correction may include the steps of: (1) analyzing a difference in attributes between the projection surfaces; and (2) performing image correction to compensate for the difference in attributes based on the analyzed information on the difference in attributes between the projection surfaces.
首先，步骤(1)(分析投影面之间的属性的差异)可优选地通过管理设备400来执行。在这种情况下，管理设备400可通过各种方式分析关于投影面之间的属性的差异的信息，诸如使用存储在内部数据库中的信息的方法、使用成像设备的方法等。此处，使用存储在内部数据库中的信息的方法指的是其中关于每个投影面的属性的各信息(例如，色度信息、亮度信息、反射率信息、质量信息等)被存储在数据库中，以使得管理设备400基于存储在数据库中的信息分析关于投影面之间的属性的差异的信息的方法。此外，使用成像设备的方法指的是其中用于对多个投影面进行成像的成像设备被提供用于基于该成像设备所获取的图像分析关于投影面之间的属性的差异的信息的方法。First, step (1) (analyzing the difference in attributes between projection surfaces) can preferably be performed by the management device 400 . In this case, the management device 400 may analyze information on the difference in properties between projection surfaces in various ways, such as a method using information stored in an internal database, a method using an imaging device, and the like. Here, the method of using information stored in the internal database refers to a method in which individual information on attributes of each projection surface (for example, chromaticity information, luminance information, reflectance information, quality information, etc.) is stored in the database , so that the management device 400 analyzes the information on the difference in properties between the projection surfaces based on the information stored in the database. In addition, the method using an imaging device refers to a method in which an imaging device for imaging a plurality of projection surfaces is provided for analyzing information on differences in properties between projection surfaces based on images acquired by the imaging device.
接着，步骤(2)(执行图像校正以便基于所分析的关于投影面之间的属性的差异的信息补偿属性的差异)也可通过管理设备400来执行。在这种情况下，管理设备400可校正投射在相应的投影面上的图像，以便基于所分析的关于投影面之间的属性的差异的信息(例如，色度信息、亮度信息、反射率信息、质量信息等)来补偿属性的差异，从而减小投射在多个投影面上的图像之间的不均匀性。Next, step (2) (performing image correction to compensate for the difference in properties based on the analyzed information about the difference in properties between the projection surfaces) can also be performed by the management device 400 . In this case, the management device 400 may correct the images projected on the corresponding projection surfaces so that based on the analyzed information on the difference in properties between the projection surfaces (for example, chromaticity information, luminance information, reflectance information , quality information, etc.) to compensate for differences in attributes, thereby reducing the inhomogeneity between images projected on multiple projection surfaces.
典型地，现在将描述基于关于投影面之间的色度的差异的信息的校正(下面将要描述的过程(当然)可应用于基于亮度的差异、反射率的差异、质量的差异等的校正)。首先，管理设备400可基于各个投影面的色度信息计算关于投影面之间的色度的差异的信息。具体来说，管理设备400可设置一个基准投影面然后计算关于各个投影面的色度的相对差异的信息。例如，以这样的方式来计算关于色度的相对差异的信息，即“投影面A具有比基准投影面高50的红色(R)色阶、比基准投影面高40的绿色(G)色阶以及与基准投影面相同的蓝色(B)色阶”。在以这种方式计算出关于各投影面的色度的差异的信息之后，可基于所计算的信息以这样的方式来校正图像，使得例如“将投射在投影面A上的图像的R色阶降低50、将G色阶降低40并且保持B色阶不变”。因此，投影面的色度的差异可被补偿。Typically, correction based on information on a difference in chromaticity between projection surfaces will now be described (the procedure to be described below is (of course) applicable to correction based on a difference in luminance, a difference in reflectance, a difference in quality, etc.) . First, the management apparatus 400 may calculate information on a difference in chromaticity between projection surfaces based on chromaticity information of respective projection surfaces. Specifically, the management device 400 may set a reference projection surface and then calculate information on relative differences in chromaticity of each projection surface. For example, information on the relative difference in chromaticity is calculated in such a way that "projection surface A has a red (R) gradation 50 higher than the reference projection surface, and a green (G) gradation 40 higher than the reference projection surface." and the same shade of blue (B) as the reference projection surface". After the information on the difference in chromaticity of each projection surface is calculated in this way, the image can be corrected based on the calculated information in such a way that, for example, "The R gradation of the image projected on the projection surface A Lowered by 50, lowered the G levels by 40 and left the B levels unchanged". Therefore, the difference in chromaticity of the projection surface can be compensated.
此外，对多个投影面的属性的差异的分析可以用除了设置基准投影面的方法之外的各种方式来执行。例如，能够计算多个投影面的属性的代表值(例如，平均值、中间值、模式值等)然后基于所计算的代表值分析属性的相对差异。Furthermore, the analysis of the difference in the properties of a plurality of projection surfaces can be performed in various ways other than the method of setting a reference projection surface. For example, it is possible to calculate representative values (eg, mean values, median values, mode values, etc.) for attributes of multiple projected surfaces and then analyze relative differences in attributes based on the calculated representative values.
随后，将参照图5至图9对根据本发明的实施方式的“多投影系统”进行描述。Subsequently, a "multi-projection system" according to an embodiment of the present invention will be described with reference to FIGS. 5 to 9 .
参照图5至图7，根据本发明的实施方式的多投影系统可包括不彼此平行地布置的多个投影面100，以及用于将图像投射在该多个投影面100上的两个或更多个投影设备300，并且该两个或更多个投影设备300中的每一个可包括其中投射光在其到达投影面之前被折射的折射投影设备310。Referring to FIGS. 5 to 7 , a multi-projection system according to an embodiment of the present invention may include a plurality of projection surfaces 100 arranged not parallel to each other, and two or more projection surfaces for projecting images on the plurality of projection surfaces 100 . A plurality of projection devices 300, and each of the two or more projection devices 300 may include a refraction projection device 310 in which projected light is refracted before it reaches a projection surface.
此外，多投影系统可进一步包括投射光折射单元200，该投射光折射单元200用于使折射投影设备310的投射光折射。In addition, the multi-projection system may further include a projection light refraction unit 200 for refracting the projection light of the refraction projection device 310 .
折射投影设备310指的是其投射光在其到达具体的投影面100之前在其中被折射的投影设备。具体地，折射投影设备310指的是能够利用折射的投射光将图像投射在甚至是没有面对其布置(即，沿除前方以外的其它方向布置)的投影面上的投影设备300。The refractive projection device 310 refers to a projection device in which projected light is refracted before it reaches a specific projection surface 100 . Specifically, the refraction projection device 310 refers to the projection device 300 capable of projecting an image using refracted projection light even on a projection surface not disposed facing it (ie, disposed in a direction other than the front).
优选地，借助于沿投射光的方向安装的投射光折射单元200，该折射投影设备310可使其投射光能够以各种方式被折射。Preferably, the refraction projection device 310 enables its projection light to be refracted in various ways by means of the projection light refraction unit 200 installed along the projection light direction.
投射光折射单元200被配置为使通过折射投影设备310在三维空间中以不同的角度投射的投射光折射。The projection light refraction unit 200 is configured to refract projection light projected at different angles in a three-dimensional space by the refraction projection device 310 .
投射光折射单元200可利用各种能够使折射投影设备310的投射光折射的光学设备来实现，诸如反射镜210、棱镜220(例如，直角棱镜、普通三棱镜或者五棱镜)等。此外，投射光折射单元200可包括两个或更多个光学设备，诸如两个或更多个反射镜210、两个或更多个棱镜220、两个或更多个反射镜210和棱镜220，并且在图13中示出了该实施方式。The projection light refraction unit 200 can be realized by using various optical devices capable of refracting the projection light of the refraction projection device 310 , such as a mirror 210 and a prism 220 (for example, a rectangular prism, a common triangular prism or a pentaprism) and the like. In addition, the projection light refraction unit 200 may include two or more optical devices, such as two or more mirrors 210, two or more prisms 220, two or more mirrors 210, and a prism 220. , and this embodiment is shown in FIG. 13 .
此外，优选的是，投射光折射单元200沿折射投影设备310的投射光的方向来安装。例如，投射光折射单元200可被安装在折射投影设备310的灯的前方，以便使从该灯射出的投射光折射。In addition, it is preferable that the projection light refraction unit 200 is installed along a direction in which projection light of the projection device 310 is refracted. For example, the projection light refraction unit 200 may be installed in front of a lamp of the refraction projection device 310 so as to refract the projection light emitted from the lamp.
此外，投射光折射单元200可被配置以移动其机身，并且折射投影设备310的投射光被折射的角度可通过该机身的移动而改变。具体地，投射光折射单元200可被配置为执行三维空间中的线性运动或者三维空间中的旋转运动，并且折射投影设备310的投射光被折射的角度可通过该线性或旋转运动而被改变(供参考，该线性或旋转运动可以在对于本领域的技术人员来说显而易见的范围内以各种方式来实现，诸如致动器、连接节点、轨道、长度可调的框架等)。In addition, the projection light refraction unit 200 may be configured to move its body, and the angle at which the projection light of the refraction projection device 310 is refracted may be changed by the movement of the body. Specifically, the projection light refraction unit 200 may be configured to perform a linear motion in a three-dimensional space or a rotational motion in a three-dimensional space, and the angle at which the projection light of the refraction projection device 310 is refracted may be changed by the linear or rotational motion ( For reference, this linear or rotational movement can be realized in various ways within the scope obvious to those skilled in the art, such as actuators, joint nodes, tracks, length-adjustable frames, etc.).
因此，折射投影设备310的投射光可在三维空间中通过投射光折射单元200的运动沿各种方向被折射，并因此折射投影设备310的投射光可选择性地到达在三维空间中沿各种方向布置的全部多个投影面100。例如，如图5中所示，折射投影设备310的投射光可选择性地到达左投影面或右投影面，并且如图6中所示，可选择性地到达上投影面或下投影面。此外，折射投影设备310的投射光可选择性地到达剧场中存在的各个其它投影面。Therefore, the projection light of the refraction projection device 310 can be refracted in various directions in the three-dimensional space by the movement of the projection light refraction unit 200, and thus the projection light of the refraction projection device 310 can selectively arrive at various directions in the three-dimensional space. All the plurality of projection surfaces 100 arranged in different directions. For example, as shown in FIG. 5 , the projection light of the refraction projection device 310 may selectively reach the left or right projection surface, and as shown in FIG. 6 , may selectively reach the upper or lower projection surface. In addition, the projection light of the refraction projection device 310 can selectively reach various other projection surfaces existing in the theater.
作为结果，通过投射光折射单元200的运动，折射投影设备310可选择性地将图像投射在全部多个投影面100上，并因此折射投影设备310可被用于多个目的。也就是说，通过使折射投影设备300的投射光折射的操作，折射投影设备310可被用于各种目的，诸如将图像投射在左投影面上、将图像投射在右投影面上、将图像投射在上投影面上等。As a result, the refraction projection device 310 may selectively project images on all of the plurality of projection surfaces 100 through the movement of the projection light refraction unit 200, and thus the refraction projection device 310 may be used for various purposes. That is, the refraction projection device 310 can be used for various purposes such as projecting an image on a left projection surface, projecting an image on a right projection surface, projecting an image Projected on the upper projection surface, etc.
此外，折射投影设备310的机身也可被配置为可移动。具体地，折射投影设备310的机身也可被配置为执行三维空间中的线性运动或旋转运动，并且折射投影设备310的该运动可更加多样并精确地改变投射光的折射角度。In addition, the body of the refraction projection device 310 may also be configured to be movable. Specifically, the body of the refraction projection device 310 may also be configured to perform a linear motion or a rotational motion in a three-dimensional space, and this motion of the refraction projection device 310 may more diversely and precisely change the refraction angle of projected light.
可通过管理设备400来控制折射投影设备310和投射光折射单元200的上述操作。具体地，在电连接折射投影设备310和投射光折射单元200之后，管理设备400可控制该折射投影设备310的操作和该投射光折射单元200的操作。例如，管理设备400可被连接到用于移动投射光折射单元200的致动器，并控制该投射光折射单元200的运动，从而控制投射光被折射的角度。The above-described operations of the refraction projection device 310 and the projection light refraction unit 200 may be controlled by the management device 400 . Specifically, after electrically connecting the refraction projection device 310 and the projection light refraction unit 200 , the management device 400 can control the operation of the refraction projection device 310 and the projection light refraction unit 200 . For example, the management device 400 may be connected to an actuator for moving the projection light refraction unit 200, and control the movement of the projection light refraction unit 200, thereby controlling the angle at which the projection light is refracted.
此外，管理设备400可将图像数据发送到折射投影设备310并控制该折射投影设备310的运动。此外，管理设备400可根据折射投影设备310的投射光面对的投影面100的类型发送不同的图像数据。例如，当折射投影设备310的投射光面对左投影面100时，管理设备400可发送将要投射在左投影面100上的图像数据，并且当折射投影设备310的投射光面对右投影面100时，管理设备400可发送将要投射在右投影面100上的图像数据。此外，当图像被投射在上投影面100、下投影面100、前投影面100、后投影面100等上时，管理设备400可发送不同的将被投射在相应的投影面100上的图像数据(同时，当多个投影面100是不同类型时，管理设备400可基于投影面100之间的属性的差异校正图像数据，然后发送校正后的图像数据)。In addition, the management device 400 may transmit image data to the refraction projection device 310 and control the movement of the refraction projection device 310 . In addition, the management device 400 may transmit different image data according to the type of the projection surface 100 on which the projection light of the refraction projection device 310 faces. For example, when the projection light of the refraction projection device 310 faces the left projection surface 100 , the management device 400 may send image data to be projected on the left projection surface 100 , and when the projection light of the refraction projection device 310 faces the right projection surface 100 , the management device 400 may transmit image data to be projected on the right projection surface 100 . In addition, when an image is projected on the upper projection surface 100, the lower projection surface 100, the front projection surface 100, the rear projection surface 100, etc., the management device 400 may transmit different image data to be projected on the corresponding projection surface 100 (Meanwhile, when the plurality of projection surfaces 100 are of different types, the management device 400 may correct the image data based on the difference in properties between the projection surfaces 100 and then transmit the corrected image data).
此外，管理设备400可基于外部输入等实时控制投射光折射单元200的操作，但是也可基于预先存储的数据库控制投射光折射单元200的操作。此处，数据库可存储多个使折射投影设备310的投射光能够到达相应的投影面100的操作模式信息，诸如用于将投射光折射到左投影面100的操作模式信息(例如，反射面的布置角度、三维位置等)、用于将投射光折射到右投影面100的操作模式信息、用于将投射光折射到顶部投影面100的操作模式信息等。因此，管理设备400可基于数据库选择性地控制投射光折射单元200的操作，从而使折射投影设备310的投射光能够基于该控制选择性地到达多个投影面100。In addition, the management device 400 may control the operation of the projection light refraction unit 200 in real time based on external input or the like, but may also control the operation of the projection light refraction unit 200 based on a pre-stored database. Here, the database may store a plurality of operation mode information enabling the projection light of the refraction projection device 310 to reach the corresponding projection surface 100, such as operation mode information for refracting the projection light to the left projection surface 100 (for example, Arrangement angle, three-dimensional position, etc.), operation mode information for refracting projection light to the right projection surface 100, operation mode information for refracting projection light to the top projection surface 100, and the like. Therefore, the management device 400 can selectively control the operation of the projection light refraction unit 200 based on the database, so that the projection light of the refraction projection device 310 can selectively reach the plurality of projection surfaces 100 based on the control.
此外，投射光折射单元200可包括诸如3轴传感器等的位置传感器。因此，管理设备400可被连接到该传感器，以反馈投射光折射单元200的操作状态并管理投射光折射单元200是否正常操作，从而降低与投射光的折射相关联的误差。In addition, the projection light refraction unit 200 may include a position sensor such as a 3-axis sensor or the like. Therefore, the management device 400 may be connected to the sensor to feed back the operation status of the projection light refraction unit 200 and manage whether the projection light refraction unit 200 is operating normally, thereby reducing errors associated with refraction of projection light.
此外，折射投影设备310可包括能够分析性能信息的各种传感器。具体地，用于检测用于生成投射光的灯的光强度的光强度传感器、用于检测设备中的湿度的湿度传感器、用于检测设备中的温度的温度传感器等可被安装在折射投影设备310中，并且这些传感器可被连接到管理设备并被控制。Additionally, the refraction projection device 310 may include various sensors capable of analyzing performance information. Specifically, a light intensity sensor for detecting the light intensity of a lamp for generating projection light, a humidity sensor for detecting humidity in the device, a temperature sensor for detecting temperature in the device, etc. may be installed in the refraction projection device 310, and these sensors can be connected to a management device and controlled.
因此，管理设备400可管理折射投影设备310的光强度信息、维护信息(温度、湿度)等，从而管理与亮度、故障风险等有关的设备的性能。Accordingly, the management device 400 can manage light intensity information, maintenance information (temperature, humidity), etc. of the refraction projection device 310, thereby managing device performance related to brightness, failure risk, and the like.
参照图8，根据本发明的实施方式的多投影系统可包括多个折射投影设备310和多个投射光折射单元200。Referring to FIG. 8 , a multi-projection system according to an embodiment of the present invention may include a plurality of refraction projection devices 310 and a plurality of projection light refraction units 200 .
此处，优选的是，多个折射投影设备310以1:1的比例与多个投射光折射单元200相匹配，并且还优选的是，每个投射光折射单元200沿每个折射投影设备310的投射光的方向安装，以便使每个折射投影设备310的投射光折射。Here, it is preferable that a plurality of refraction projection devices 310 are matched with a plurality of projection light refraction units 200 at a ratio of 1:1, and it is also preferable that each projection light refraction unit 200 is aligned along each refraction projection device 310 The direction of the projected light is installed so that the projected light of each refraction projection device 310 is refracted.
此外，多个折射投影设备310和多个投射光折射单元200可被连接到管理设备400，并且通常由该管理设备400来控制。在这种情况下，管理设备400可通过控制各个投射光折射单元200来控制各个折射投影设备310的投射光被折射的角度，从而使各个折射投影设备310的投射光能够基于该控制选择性地到达多个投影面100。而且，管理设备400可通过匹配各个折射投影设备310和各个投射光折射单元200来配置多个控制组(例如，投影设备1-投射光折射单元1、投影设备2-投射光折射单元2等)，并且可执行控制组单元中的控制操作。In addition, the plurality of refraction projection devices 310 and the plurality of projection light refraction units 200 may be connected to the management device 400 and generally controlled by the management device 400 . In this case, the management device 400 can control the angle at which the projection light of each refraction projection device 310 is refracted by controlling each projection light refraction unit 200, so that the projection light of each refraction projection device 310 can selectively Multiple projection surfaces 100 are reached. Also, the management device 400 can configure a plurality of control groups (for example, projection device 1 - projection light refraction unit 1, projection device 2 - projection light refraction unit 2, etc.) by matching each refraction projection device 310 and each projection light refraction unit 200 , and the control operations in the control group unit can be performed.
此外，管理设备400可包括存储用于控制多个折射投影设备310和多个投射光折射单元200的操作的信息的数据库，并且可基于存储在该数据库中的信息控制多个折射投影设备310和多个投射光折射单元200的操作。现在将参照图9描述数据库的实施方式。每个折射投影设备310的识别信息和每个投射光折射单元200的操作信息可按照匹配的方式被存储在数据库中。此外，每个投射光折射单元200的操作信息可包含用于选择性地将投射光折射到多个投影面100上的多个操作模式信息(例如，反射面的布置角度、三维位置等)。例如，“投影设备1”的识别信息和“投射光折射单元1”的操作信息可按照匹配的方式被存储在数据库中。此处，“投射光折射单元1”的操作信息可包含多个操作模式信息。具体地，“投射光折射单元1”的操作信息可包含多个操作模式信息，诸如：(i)用于将“投影设备1”的投射光折射到“投影面A”的“操作模式a”；(ii)用于将“投影设备1”的投射光折射到“投影面B”的“操作模式b”；(iii)用于将“投影设备1”的投射光折射到“投影面C”的“操作模式c”等。In addition, the management device 400 may include a database storing information for controlling the operations of the plurality of refraction projection devices 310 and the plurality of projection light refraction units 200, and may control the plurality of refraction projection devices 310 and the plurality of projection light refraction units 200 based on information stored in the database. Operation of multiple projection light refraction units 200 . An embodiment of the database will now be described with reference to FIG. 9 . Identification information of each refraction projection device 310 and operation information of each projection light refraction unit 200 may be stored in a database in a matched manner. In addition, the operation information of each projection light refraction unit 200 may include a plurality of operation mode information for selectively refracting projection light onto a plurality of projection surfaces 100 (eg, arrangement angles, three-dimensional positions, etc. of reflection surfaces). For example, identification information of "projection device 1" and operation information of "projection light refraction unit 1" may be stored in a database in a matched manner. Here, the operation information of the "projection light refraction unit 1" may include a plurality of operation mode information. Specifically, the operation information of the "projection light refraction unit 1" may include a plurality of operation mode information, such as: (i) "operation mode a" for refracting the projection light of the "projection device 1" to the "projection surface A" ; (ii) "operation mode b" for refracting the projection light of "projection device 1" to "projection surface B"; (iii) for refracting the projection light of "projection device 1" to "projection surface C" "operating mode c" etc.
因此，管理设备400可基于存储在数据库中的信息选择性地将各个折射投影设备310的投射光折射到多个投影面100上。Therefore, the management device 400 may selectively refract the projection light of each refraction projection device 310 onto the plurality of projection surfaces 100 based on the information stored in the database.
此外，优选的是，在其中由多个折射投影设备310投射的投射光彼此不会重叠的范围内设定存储在数据库中的各个投射光折射单元200的操作信息。例如，当投影设备1借助于以操作模式a操作的投射光折射单元1将图像投射在投影面A上时，以及当投影设备2借助于以操作模式b操作的投射光折射单元2将图像投射在与投影面A毗邻的投影面B上时，关于投射光折射单元1的操作模式a的信息(例如反射面的布置角度、三维位置等)和关于投射光折射单元2的操作模式b的信息可被设定，并且关于其它操作模式的信息可在此范围内被设定。Further, it is preferable to set the operation information of the respective projection light refraction units 200 stored in the database within a range in which the projection lights projected by the plurality of refraction projection devices 310 do not overlap with each other. For example, when projection device 1 projects an image on projection surface A by means of projection light refraction unit 1 operating in operation mode a, and when projection device 2 projects an image by means of projection light refraction unit 2 operating in operation mode b When on the projection surface B adjacent to the projection surface A, information about the operation mode a of the projection light refraction unit 1 (such as the arrangement angle of the reflection surface, three-dimensional position, etc.) and information about the operation mode b of the projection light refraction unit 2 can be set, and information about other operation modes can be set within this range.
多投影系统可使用多个折射投影设备310将图像投射在多个投影面100上。然而，在这种情况下，由于各个折射投影设备310可选择性地将图像投射在全部多个投影面100上，因此负责各个投影面100的折射投影设备310不是预先确定的，不过其可在管理设备400的控制下被改变。A multi-projection system may use multiple refractive projection devices 310 to project images on multiple projection surfaces 100 . However, in this case, since each refraction projection device 310 can selectively project an image on all of the plurality of projection surfaces 100, the refraction projection device 310 in charge of each projection surface 100 is not predetermined, but it can be selected at are changed under the control of the management device 400 .
例如，当假设多个投影面100包括投影面A、投影面B、投影面C和投影面D，并且多个折射投影设备310包括投影设备1、投影设备2、投影设备3和投影设备4时，用于将图像投射在各个投影面100上的折射投影设备310可在管理设备400的控制下被改变。具体地，在管理设备400的控制下，多投影系统可按照下列方式进行配置：(i)投影设备1将图像投射在投影面A上、投影设备3将图像投射在投影面B上、投影设备4将图像投射在投影面C上、以及投影设备1将图像投射在投影面D上；或者(ii)投影设备2将图像投射在投影面A上、投影设备4将图像投射在投影面B上、投影设备1将图像投射在投影面C上、投影设备3将图像投射在投影面D上，并且该多投影系统可利用“折射投影设备310”和“投影面100”的各种其它组合进行配置。For example, when it is assumed that the plurality of projection planes 100 includes projection plane A, projection plane B, projection plane C, and projection plane D, and the plurality of refraction projection devices 310 includes projection device 1, projection device 2, projection device 3, and projection device 4 , the refraction projection device 310 for projecting an image on each projection surface 100 may be changed under the control of the management device 400 . Specifically, under the control of the management device 400, the multi-projection system can be configured in the following manner: (i) the projection device 1 projects the image on the projection surface A, the projection device 3 projects the image on the projection surface B, and the projection device 3 projects the image on the projection surface B. 4 project the image on the projection surface C, and the projection device 1 projects the image on the projection surface D; or (ii) the projection device 2 projects the image on the projection surface A, and the projection device 4 projects the image on the projection surface B , the projection device 1 projects an image on a projection surface C, and the projection device 3 projects an image on a projection surface D, and the multi-projection system can utilize various other combinations of "refractive projection device 310" and "projection surface 100" to perform configure.
此外，由于多投影系统使用多个无需被安装成面对具体的投影面100的折射投影设备310来投射图像，因此该多个折射投影设备310可在剧场中的各种位置自由布置。例如，多投影系统可将多个折射投影设备310一起布置在特定空间中或者观众的视野之外的盲区或后方中。因此，多投影系统可利用这种布置结构轻易地执行对折射投影设备310的整体管理，并且可防止由于投影设备300出现在视野范围内而降低观众的沉浸感。In addition, since the multi-projection system projects images using a plurality of refraction projection devices 310 that need not be installed to face a specific projection surface 100, the plurality of refraction projection devices 310 can be freely arranged at various positions in the theater. For example, a multi-projection system may arrange a plurality of refraction projection devices 310 together in a certain space or in a blind area or rear outside the viewer's field of view. Therefore, the multi-projection system can easily perform overall management of the refraction projection device 310 using this arrangement structure, and can prevent the viewer's sense of immersion from being degraded due to the projection device 300 appearing in the field of view.
此外，多投影系统可包括比用以将图像投射在多个投影面100上所需的投影设备的数量更多数量的折射投影设备310。也就是说，如果用于将图像投射在多个投影面100上所必需的投影设备的数量是N，则多投影系统可包括大于N的M个折射投影设备310。因此，在该实施方式中，多投影系统可根据一定标准从所准备的M个折射投影设备310中选择N个折射投影设备310，并可使用所选择的N个折射投影设备310将图像投射在多个投影面100上。Furthermore, a multi-projection system may include a greater number of refractive projection devices 310 than is required to project images on multiple projection surfaces 100 . That is, if the number of projection devices necessary for projecting images on the plurality of projection surfaces 100 is N, the multi-projection system may include more than N M refraction projection devices 310 . Therefore, in this embodiment, the multi-projection system can select N refraction projection devices 310 from the prepared M refraction projection devices 310 according to a certain standard, and can use the selected N refraction projection devices 310 to project an image on on multiple projection surfaces 100 .
此处，多投影系统通过其来选择将被用于图像投射的N个折射投影设备310的标准可基于各种信息来设定，但是可优选地基于各个折射投影设备310的性能信息(例如，光强度信息、维护信息等)来设定。这样做的原因是，可基于各个折射投影设备310的性能信息确保投射在相应的投影面100上的图像的质量，并且具有性能问题的折射投影设备可被自动去除。Here, the criteria by which the multi-projection system selects N refraction projection devices 310 to be used for image projection may be set based on various information, but may preferably be based on performance information of each refraction projection device 310 (for example, light intensity information, maintenance information, etc.) to set. The reason for this is that the quality of an image projected on the corresponding projection surface 100 can be ensured based on the performance information of each refraction projection device 310, and a refraction projection device having a performance problem can be automatically removed.
此外，在这种情况下，各个折射投影设备310的性能分析以及将被用于图像投射的折射投影设备310的选择可通过管理设备400来执行。具体地，管理设备400可分析M个投影设备300的性能然后选择N个将被用于图像投射的折射投影设备310。此外，管理设备400可以通过控制所选择的投影设备300的投射光被折射的角度使图像能够被投射在多个投影面100上。例如，管理设备400可分析各个折射投影设备310的光强度信息，然后选择具有较高光强度的折射投影设备。此外，管理设备400可分析关于各个折射投影设备310的内部温度或湿度的信息，然后排除具有超出预定参考值的内部温度或湿度的折射投影设备。而且，管理设备400可收集各个折射投影设备310的分辨率信息，然后选择具有较高分辨率的折射投影设备。另外，管理设备400可收集各个折射投影设备300的维修信息，然后排除具有频繁的维修历史的折射投影设备。Also, in this case, performance analysis of each refraction projection device 310 and selection of a refraction projection device 310 to be used for image projection may be performed through the management device 400 . Specifically, the management device 400 may analyze the performance of the M projection devices 300 and then select N refraction projection devices 310 to be used for image projection. In addition, the management device 400 may enable images to be projected on the plurality of projection surfaces 100 by controlling the angle at which the projection light of the selected projection device 300 is refracted. For example, the management device 400 may analyze light intensity information of each refraction projection device 310, and then select a refraction projection device with higher light intensity. Also, the management device 400 may analyze information on the internal temperature or humidity of each refraction projection device 310 and then exclude a refraction projection device having an internal temperature or humidity exceeding a predetermined reference value. Also, the management device 400 may collect resolution information of each refraction projection device 310, and then select a refraction projection device with a higher resolution. In addition, the management device 400 may collect maintenance information of each refraction projection device 300, and then exclude refraction projection devices with frequent maintenance histories.
现在将参照图10描述实施方式。管理设备400可基于性能信息从总共五个投射光折射单元310中选择三个折射投影设备310(投影设备1、3和4)，并且可通过控制所选择的投影设备1和相对应的投射光折射单元1、所选择的投影设备3和相对应的投射光折射单元3、所选择的投影设备4和相对应的投射光折射单元4使图像能够被投射在投影面A、B和C上。此外，由于所选择的投射光折射单元中的每一个都可将图像投射在投影面A、B和C上，因此管理设备400可自由地确定将图像投射在相应的投影面100上的折射投影设备310。然而，在图10的实施方式中，管理设备400以1→C、3→A以及4→B的形式控制图像投射操作。因此，在这种情况下，管理设备400将将要被投射在投影面C上的图像数据发送给投影设备1、将将要被投射在投影面A上的图像数据发送给投影设备3、将将要被投射在投影面B上的图像数据发送给投影设备4。An embodiment will now be described with reference to FIG. 10 . The management device 400 can select three refraction projection devices 310 (projection devices 1, 3, and 4) from a total of five projection light refraction units 310 based on the performance information, and can control the selected projection device 1 and the corresponding projection light Refraction unit 1 , selected projection device 3 and corresponding projection light refraction unit 3 , selected projection device 4 and corresponding projection light refraction unit 4 enable images to be projected on projection surfaces A, B and C. In addition, since each of the selected projection light refraction units can project an image on the projection surfaces A, B, and C, the management device 400 can freely determine the refraction projection to project the image on the corresponding projection surface 100 device 310 . However, in the embodiment of FIG. 10 , the management device 400 controls the image projection operation in the form of 1→C, 3→A, and 4→B. Therefore, in this case, the management device 400 sends the image data to be projected on the projection surface C to the projection device 1, the image data to be projected on the projection surface A to the projection device 3, the image data to be projected on the projection surface A to the projection device 3, and the image data to be projected on the projection surface A to the projection device 3, The image data projected on the projection plane B is sent to the projection device 4 .
随后，将参照图11和12对根据本发明的另一个实施方式的多投影系统进行描述。Subsequently, a multi-projection system according to another embodiment of the present invention will be described with reference to FIGS. 11 and 12 .
参照图11，根据本发明的另一个实施方式的多投影系统可包括多个投影面100，并且在这种情况下，该多个投影面100可被分成主投影面110和辅投影面120。Referring to FIG. 11 , a multi-projection system according to another embodiment of the present invention may include a plurality of projection surfaces 100 , and in this case, the plurality of projection surfaces 100 may be divided into a main projection surface 110 and an auxiliary projection surface 120 .
此处，主投影面110是主图像将被投射其上的投影面，并且指的是被布置在观众席的前方以便贯穿整个放映时间投射主图像的投影面100。Here, the main projection surface 110 is a projection surface on which the main image is projected, and refers to the projection surface 100 arranged in front of the auditorium so as to project the main image throughout the show time.
此外，辅投影面120围绕主投影面110布置，并且指的是用于辅助主图像的辅图像被投射其上的投影面。辅图像可按各种方式被投射在辅投影面120上。例如，(i)与主图像同步的辅图像可贯穿整个放映时间被投射、或者(ii)与主图像同步的辅图像可在贯穿整个放映时间中的具体时间被投射。此外，在后者的情况下，可基于主图像的时间代码或者基于主图像中的目标的识别来确定该辅图像被投射的具体时间。例如，管理设备400可控制将仅在整个放映时间中的预定的时间区域中被投射的辅图像，或者可实时分析主图像(例如，外观、颜色、动作模式等)然后控制辅图像仅在识别到预定的具体目标(例如，雨、火焰、云等)的时间被投射。Also, the auxiliary projection plane 120 is arranged around the main projection plane 110 and refers to a projection plane on which an auxiliary image for assisting the main image is projected. The auxiliary image may be projected on the auxiliary projection surface 120 in various ways. For example, (i) secondary images synchronized with the main image may be projected throughout the showtime, or (ii) secondary images synchronized with the main image may be projected at specific times throughout the showtime. Also, in the latter case, the specific time at which the secondary image was projected may be determined based on the time code of the primary image or based on the identification of an object in the primary image. For example, the management device 400 may control the auxiliary image to be projected only in a predetermined time zone throughout the show time, or may analyze the main image (eg, appearance, color, motion pattern, etc.) The time to a predetermined specific target (eg, rain, fire, cloud, etc.) is projected.
根据本发明的另一个实施方式的多投影系统可包括用于将主图像投射在主投影面110上的主投影设备330，以及用于将辅图像投射在辅投影面120上的辅投影设备340，并且优选的是，该辅投影面120和该辅投影设备的数量分别为两个或更多个。此外，可通过管理设备400来控制主投影设备330的操作和辅投影设备340的操作。A multi-projection system according to another embodiment of the present invention may include a main projection device 330 for projecting a main image on the main projection surface 110 , and an auxiliary projection device 340 for projecting an auxiliary image on the auxiliary projection surface 120 , and preferably, the number of the auxiliary projection surface 120 and the auxiliary projection device is two or more. Also, the operation of the main projection device 330 and the operation of the auxiliary projection device 340 may be controlled through the management device 400 .
此外，优选的是，按照上述的折射投影设备310的形式对两个或更多个辅投影设备340进行配置，并因此该两个或更多个辅投影设备340可避免面对具体的辅投影面120地进行安装。具体地说，两个或更多个辅投影设备340可与主投影设备330一起被安装成面对主投影面110，并且例如可被安装在相同的空间(诸如放映室)中。因此，可通过这种集中布置容易地执行多个投影设备300的管理。In addition, it is preferable that two or more auxiliary projection devices 340 are configured in the form of the above-mentioned refraction projection device 310, and thus the two or more auxiliary projection devices 340 can avoid facing specific auxiliary projection devices. Surface 120 for installation. Specifically, two or more auxiliary projection devices 340 may be installed to face the main projection surface 110 together with the main projection device 330, and may be installed in the same space such as a projection room, for example. Therefore, management of a plurality of projection apparatuses 300 can be easily performed through such a centralized arrangement.
此外，可提供多于将图像投射在两个或更多个辅投影面120上所需的投影设备的数量的两个或更多个辅投影设备340。因此，在这种情况下，管理设备400可分析该两个或更多个辅投影设备340的性能，然后基于分析信息选择将被用于图像投射的辅投影设备340。此外，管理设备400可只使用所选择的辅投影设备340将图像投射在两个或更多个投影面120上(上面关于性能分析的描述可被应用于此)。Also, two or more auxiliary projection devices 340 may be provided which is more than the number of projection devices required to project images on two or more auxiliary projection surfaces 120 . Therefore, in this case, the management device 400 may analyze the performance of the two or more auxiliary projection devices 340, and then select the auxiliary projection device 340 to be used for image projection based on the analysis information. In addition, the management device 400 may project images on two or more projection surfaces 120 using only the selected auxiliary projection device 340 (the above description about performance analysis may be applied here).
此外，当主投影设备330未正常操作时，根据本发明的另一个实施方式的多投影系统可以使以折射投影设备310的形式配置的辅投影设备340能够替代该主投影设备330。由于以折射投影设备310的形式配置的辅投影设备340可通过投射光的折射甚至将图像投射在主投影面110上，因此可配置这种替代系统。In addition, when the main projection device 330 is not operating normally, the multi-projection system according to another embodiment of the present invention may enable the auxiliary projection device 340 configured in the form of the refraction projection device 310 to replace the main projection device 330 . Such an alternative system can be configured because the auxiliary projection device 340 configured in the form of the refraction projection device 310 can even project an image on the main projection surface 110 through refraction of projected light.
在这种情况下，管理设备400可以从两个或更多个辅投影设备340中选择将用作主投影设备330的具体投影设备300，并将主图像数据发送到所选择的投影设备300，以使得所选择的投影设备300用作主投影设备330。In this case, the management device 400 may select a specific projection device 300 to be used as the main projection device 330 from two or more auxiliary projection devices 340, and transmit the main image data to the selected projection device 300, So that the selected projection device 300 is used as the main projection device 330 .
此外，管理设备400可以按各种方式选择用作主投影设备330的具体投影设备300。例如，管理设备400可分析两个或更多个辅投影设备340的性能，并且使具有最佳性能的辅投影设备340能够替代主投影设备300。在这种情况下，管理设备400可通过分析各个辅投影设备340的光强度信息、维护信息(温度信息、湿度信息)、分辨率信息等来分析各个辅投影设备340的性能，并可使被确定为具有最佳性能的辅投影设备340能够替代主投影设备330。In addition, the management device 400 may select a specific projection device 300 serving as the master projection device 330 in various ways. For example, the management device 400 may analyze the performance of two or more auxiliary projection devices 340 and enable the auxiliary projection device 340 having the best performance to replace the main projection device 300 . In this case, the management device 400 can analyze the performance of each auxiliary projection device 340 by analyzing the light intensity information, maintenance information (temperature information, humidity information), resolution information, etc. of each auxiliary projection device 340, and can make the The secondary projection device 340 determined to have the best performance can replace the primary projection device 330 .
参照图12，示出了其中用于将主图像投射在主投影面110上的主投影设备330出现故障的示例。在这种情况下，为了选择将替代主投影设备330的辅投影设备340，管理设备400分析折射投影设备310的性能(即，辅投影设备1、2、3等)，并基于分析结果选择具有最佳性能的辅投影设备(例如，辅投影设备2)。此外，管理设备400将主图像数据发送到所选择的辅投影设备，并通过控制所选择的辅投影设备和相应的投射光折射单元的操作使所选择的辅投影设备的投射光能够直接到达主投影面110。Referring to FIG. 12 , there is shown an example in which the main projection device 330 for projecting the main image on the main projection surface 110 fails. In this case, in order to select the auxiliary projection device 340 that will replace the main projection device 330, the management device 400 analyzes the performance of the refraction projection device 310 (ie, auxiliary projection devices 1, 2, 3, etc.), and selects a project with The auxiliary projection device with the best performance (eg, auxiliary projection device 2). In addition, the management device 400 sends the main image data to the selected auxiliary projection device, and enables the projection light of the selected auxiliary projection device to directly reach the main projection device by controlling the operation of the selected auxiliary projection device and the corresponding projection light refraction unit. Projection surface 110 .
随后，将参照图14对根据本发明的又一个实施方式的多投影系统进行描述。Subsequently, a multi-projection system according to still another embodiment of the present invention will be described with reference to FIG. 14 .
根据本发明的又一个实施方式的多投影系统可通过控制投射光折射单元200的操作最大化由折射投影设备310投射的投射面积。具体地，该多投影系统可通过控制投射光折射单元200的操作使单个折射投影设备310能够将图像投射在两个或更多个投影面上。The multi-projection system according to still another embodiment of the present invention may maximize the projection area projected by the refraction projection device 310 by controlling the operation of the projection light refraction unit 200 . Specifically, the multi-projection system can enable a single refraction projection device 310 to project images on two or more projection surfaces by controlling the operation of the projection light refraction unit 200 .
图14中示出了该实施方式。This embodiment is shown in FIG. 14 .
在这种情况下，包括在多投影系统中的管理设备400基于模拟或输入信息(通过输入设备或通信单元输入)计算投射光折射单元200的位置和角度(由此可最大化投射面积)，并可基于计算结果控制投射光折射单元200的运动。In this case, the management device 400 included in the multi-projection system calculates the position and angle of the projection light refraction unit 200 (thus maximizing the projection area) based on simulation or input information (input through the input device or communication unit), And the movement of the projection light refraction unit 200 can be controlled based on the calculation result.
此外，当具体的折射投影设备310的图像被投射在两个或更多个投影面上时，管理设备400可校正由具体的折射投影设备310所投射的图像，并且在这种情况下，该校正可基于该两个或更多个投影面之间的属性的差异来执行(这在上文已经进行了描述，并因此省略其详细描述)。此外，该校正可包括用于实现在投影面之间的边界上的流畅图像的过渡。In addition, when the image of the specific refraction projection device 310 is projected on two or more projection surfaces, the management device 400 can correct the image projected by the specific refraction projection device 310, and in this case, the Correction may be performed based on the difference in properties between the two or more projection surfaces (this has been described above, and thus a detailed description thereof will be omitted). Furthermore, this correction can include transitions for achieving a smooth image on the border between the projection surfaces.
随后，将描述根据本发明的还一个实施方式的多投影系统。Subsequently, a multi-projection system according to still another embodiment of the present invention will be described.
根据本发明的还一个实施方式的多投影系统可基于“输入信息”(用户的输入信息等)执行图像校正过程。具体地，该多投影系统可基于通过输入设备或通信单元输入的信息执行图像校正过程。A multi-projection system according to still another embodiment of the present invention may perform an image correction process based on "input information" (user's input information, etc.). Specifically, the multi-projection system may perform an image correction process based on information input through an input device or a communication unit.
在这种情况下，管理设备400可基于从各个投影设备300输入的信息生成校正资料，而不是通过其自身的计算来生成校正资料。此外，管理设备400可将所生成的校正资料存储在数据库中，并可在随后的图像校正过程中使用所存储的校正资料。In this case, the management device 400 may generate correction materials based on information input from each projection device 300 instead of generating the correction materials by its own calculation. In addition, the management device 400 may store the generated correction data in a database, and may use the stored correction data in a subsequent image correction process.
此外，当识别到投射光折射单元200的位置或角度被改变时，管理设备400可识别出需要准备新的校正资料，并且可通过通信单元或输出单元(例如，显示设备)请求新的校正信息的输入。In addition, when recognizing that the position or angle of the projection light refraction unit 200 is changed, the management device 400 may recognize that new correction materials need to be prepared, and may request new correction information through a communication unit or an output unit (for example, a display device) input of.
已经参照其优选实施方式对本发明进行了详细描述。然而，本领域技术人员应该理解，在不脱离本发明的原理和精神的情况下，可以对这些实施方式进行修改，在权利要求和权利要求的等同物中限定了本发明的范围。The invention has been described in detail with reference to its preferred embodiments. However, it should be appreciated by those skilled in the art that modifications may be made to these embodiments without departing from the principles and spirit of the invention, the scope of the invention being defined in the claims and their equivalents.
