本发明涉及增强现实技术领域，具体为一种增强现实设备。The invention relates to the technical field of augmented reality, in particular to an augmented reality device.
背景技术Background technique
随着增强现实(Augmented Reality，简称AR)技术的发展，越来越多的智能穿戴设备开始为人们所熟悉。根据成像原理，在屏幕中呈现的包括虚拟图像和现实图像的增强现实图像在人眼视网膜中的中央凹位置聚集时，成像最清晰。然而目前的增强现实设备的视野大都有限，用户体验的沉浸感不足。With the development of Augmented Reality (AR for short) technology, more and more smart wearable devices have become familiar to people. According to the imaging principle, when the augmented reality images presented on the screen, including virtual images and real images, are gathered at the fovea position in the retina of the human eye, the imaging is clearest. However, the field of vision of current augmented reality devices is mostly limited, and the sense of immersion in user experience is insufficient.
尽管通过追踪用户眼球并使现实屏幕随眼球移动的技术以用于虚拟现实设备，但这类技术仍然不很成熟，且在增强现实技术中少有应用。因此仍然需要改进的增强现实设备。Although the technology of tracking the user's eyeballs and making the real screen move with the eyeballs is used in virtual reality devices, such technology is still immature and has little application in augmented reality technology. There is therefore still a need for improved augmented reality devices.

Preferably, the ratio of the angle a to the angle b is 1:0.8 to 1:1.2, and the ratio of the angle a' to the angle b' is 1:0.8 to 1:1.2. When two separate display screens are used as the imager 7, they can be adjusted independently to provide better three-dimensional vision and augmented reality experience.

Since most parts of the augmented reality device are concentrated in the front part and some parts rotate around the user's head during work, a movable counterweight can be used to adjust the center of gravity of the device to the middle of the headband on the one hand to avoid the device from tilting forward. On the other hand, counterweights can be used to offset the momentum of component rotation to prevent the position of the device on the user's head from moving, thereby improving the three-dimensional display effect, reducing the burden and damage of the device on the user's body during long-term wearing, and providing users with more Nice augmented reality experience.
所述可穿戴增强现实设备以头盔形式提供，还可以包括外壳19和护罩18，外壳19通过固定架17固定在外部，并且在用户眼部区域具有空缺以露出用户的双眼；护罩18设置在外壳19的前部，并其通过外壳两侧的两个护罩旋钮20可旋转地固定在外壳19上，护罩18可绕护罩旋钮20旋转以可上下移动的方式遮蔽或露出用户的眼部区域。外壳19可以是不透明或透明度很低的材料制成，为用户提供阴暗环境，以更好地获得增强现实体验。护罩18由透明度较高的材料制成，或者有单向透光材料制成，以便外部内部摄像头27能够通过护罩18拍摄外部环境的图像。优选护罩18上在外部内部摄像头18对应的区域设有电控透明度层，以便在外部内部摄像头27移至该区域时控制提高该区域的透明度，当外部内部摄像头27离开该区域时控制降低该区域的透明度。The wearable augmented reality device is provided in the form of a helmet, and may also include a shell 19 and a shield 18, the shell 19 is fixed on the outside by a fixing frame 17, and has a vacancy in the user's eye area to expose the user's eyes; the shield 18 sets At the front of the shell 19, and it is rotatably fixed on the shell 19 by two shield knobs 20 on both sides of the shell, the shield 18 can be rotated around the shield knob 20 to cover or expose the user's body in a movable up and down manner. eye area. The casing 19 can be made of opaque or very low transparency material to provide a dark environment for the user to better obtain the augmented reality experience. The shield 18 is made of a material with high transparency, or made of a one-way light-transmitting material, so that the external internal camera 27 can take images of the external environment through the shield 18 . Preferably, the area corresponding to the external internal camera 18 is provided with an electronically controlled transparency layer on the shield 18, so that when the external internal camera 27 moves to this area, the transparency of this area is controlled to be increased, and when the external internal camera 27 leaves this area, the control is reduced. The transparency of the region.
在外壳19的内部还可设有用于提供电能的电源21(例如蓄电池等)和用于控制设备运行的控制器22。在头箍1的内壁上还可设有多个(优选3个、4个或更多个)可与用户头部接触的压力传感器23，用于检测头箍1对用户头部各部分的压力，控制器22根据测得的压力确定设备重心并控制移动配重块将重心调整至头箍1的中部，优选地，调整配重块直至头箍1对用户头部各部分的压力基本相等，或者调整所述重心至用户头部的几何中心。A power source 21 (such as a storage battery, etc.) for providing electric energy and a controller 22 for controlling the operation of the device can also be provided inside the casing 19 . Multiple (preferably 3, 4 or more) pressure sensors 23 that can be in contact with the user's head can also be provided on the inner wall of the headband 1 for detecting the pressure of the headband 1 on various parts of the user's head , the controller 22 determines the center of gravity of the device according to the measured pressure and controls the moving counterweight to adjust the center of gravity to the middle of the headband 1, preferably, adjust the counterweight until the pressure of the headband 1 on each part of the user's head is substantially equal, Or adjust the center of gravity to the geometric center of the user's head.
在另一个实施方式中，如图4所示，说是成像器(7)的两个成像区域是手机上通过软件分屏形成的两个成像区域。当用户眼球转动夹角a时，所述透镜24通过平移和转动使其光轴仍然保持与用户眼球光轴共轴，并且成像器7通过平移和转动使其两个成像区域的对称面转动夹角b，其中夹角a大于等于夹角b；优选地，夹角a与夹角b的比例为1:1至3:1，1:1.1至1:2.5,1:1.5至1:2等；更优选地，所述比例随夹角a的增加而增加；更优选地，夹角a与夹角b的关系式如下：In another embodiment, as shown in FIG. 4 , it is said that the two imaging areas of the imager ( 7 ) are two imaging areas formed on the mobile phone through software split screen. When the user's eyeball rotates at an angle a, the lens 24 keeps its optical axis coaxial with the user's eyeball optical axis through translation and rotation, and the imager 7 rotates the symmetrical planes of its two imaging regions through translation and rotation. Angle b, wherein angle a is greater than or equal to angle b; preferably, the ratio of angle a to angle b is 1:1 to 3:1, 1:1.1 to 1:2.5, 1:1.5 to 1:2, etc. ; More preferably, the ratio increases with the increase of the angle a; more preferably, the relationship between the angle a and the angle b is as follows:
其中，y为夹角b的弧度，x为夹角a的弧度，x的取值范围是0至e为自然常数。优选地，两个透镜24各自独立地保持其光轴与左眼和右眼光轴共轴，并且上述夹角a为左眼和右眼转动角度的平均值。Among them, y is the radian of the included angle b, x is the radian of the included angle a, and the value range of x is from 0 to e is a constant of nature. Preferably, the optical axes of the two lenses 24 are independently coaxial with the optical axes of the left eye and the right eye, and the above-mentioned included angle a is the average value of the rotation angles of the left eye and the right eye.
由于人类双眼在左右转动时并不能始终保持转动角度相同，例如双眼向左转动时，左眼通常比右眼转动更大的角度，而增强现实需要用户用双眼观察从不同角度拍摄的现实图像以形成三维立体视觉，因此成像器7在随用户眼球移动时需要同时为左眼和右眼提供增强现实图像，在用户眼球转动夹角a时成像器7转动较小的夹角b，尤其是采用上述关系式确定的夹角b，可以更好地维持三维立体视觉。Since the human eyes cannot always keep the same rotation angle when turning left and right, for example, when the eyes turn left, the left eye usually rotates at a larger angle than the right eye, and augmented reality requires users to use both eyes to observe realistic images taken from different angles In order to form a three-dimensional stereoscopic vision, the imager 7 needs to provide augmented reality images for the left eye and the right eye at the same time when the user's eyeballs move, and the imager 7 rotates at a smaller angle b when the user's eyeballs rotate at an angle Using the included angle b determined by the above relational formula can better maintain three-dimensional stereoscopic vision.
在一些情况下，所述增强现实设备的使用方法，包括：In some cases, the method of using the augmented reality device includes:
将所述增强现实设备通过头箍1佩戴在用户头上；Wearing the augmented reality device on the user's head through the headband 1;
在第一导轨2上平移和/或转动内部摄像头10以跟踪和拍摄用户的眼球以确定眼球光轴；Translate and/or rotate the internal camera 10 on the first guide rail 2 to track and photograph the user's eyeball to determine the eyeball optical axis;
在第二导轨3上平移和/或转动成像器7以便为用户提供图像并且将图像呈现在所述眼球光轴中，其中The imager 7 is translated and/or rotated on the second rail 3 to provide an image to the user and to present the image in the optical axis of the eye, wherein
在第三导轨15和第四导轨16上平移平移配重块11和/或在螺杆14上纵移配重块11以便将所述增强现实设备的重心调整到头箍1的中部。Translate the counterweight 11 on the third guide rail 15 and the fourth guide rail 16 and/or longitudinally move the counterweight 11 on the screw 14 so as to adjust the center of gravity of the augmented reality device to the middle of the headband 1 .
