In this embodiment, the table defines the following correspondence: when the distance between the person and the camera 2 is less than a first predetermined value (such as 5m), the corresponding display content is a detailed description, such as " Department store August 5-10 limited-time special offer A brand minimum 50% off; B brand minimum discount; C brand limited discount; D brand full lottery; E brand new product discount"; when the distance between the person and the camera device 2 is greater than the first When the predetermined value (such as 5m) is less than the second predetermined value (such as 10m), the corresponding display content is a general description, such as "Department store limited time special price 8/5-8/10, home appliances, clothing and more discounts after 5,000; Cosmetics 50% off"; when the distance between the person and the camera 2 is greater than the second predetermined value (such as 10m), the corresponding display content is a brief description, such as "Department store limited time special offer 2012/8/5- 8/10".
该影像获取模块11用于获取该摄像装置2摄取的展示看板前方场景图像。The image acquisition module 11 is used to acquire the scene image in front of the display board captured by the camera 2 .
该侦测模块12用于确定该获取的场景图像的各个点到摄像装置之间的距离中小于一预定距离(例如15米)的点所组成的区域，并侦测该确定的区域中是否存在人。其中，该侦测模块12侦测该确定的区域是否存在人的具体操作：该侦测模块12将该确定的区域所对应的图像与存储于存储器30中的多个不同的三维人型模板进行比较，来判断该确定的区域中是否存在人。如果该确定的区域所对应的图像中至少存在与该多个不同的三维人型模板中的一个相同的部分，则该侦测模块12确定该被确定的区域中存在人。如果该确定的区域所对应的图像中不存在与任意一个三维模板相同的部分，则该侦测模块12确定该确定的区域中不存在人。The detection module 12 is used to determine the area formed by the points that are less than a predetermined distance (for example, 15 meters) in the distance between each point of the acquired scene image and the camera device, and detect whether there is a people. Wherein, the detection module 12 detects the specific operation of whether there is a person in the determined area: the detection module 12 compares the image corresponding to the determined area with a plurality of different three-dimensional human templates stored in the memory 30 Comparison, to determine whether there is a person in the determined area. If the image corresponding to the determined area has at least the same part as one of the plurality of different three-dimensional humanoid templates, the detection module 12 determines that there is a person in the determined area. If there is no part identical to any three-dimensional template in the image corresponding to the determined area, the detection module 12 determines that there is no person in the determined area.
当该侦测模块12侦测到被确定的区域中存在人时，确定在该区域中该人到摄像装置2之间的距离，其中，当该侦测模块12侦测该确定的区域中存在多个人则分别确定各个人与摄像装置2之间的距离，并计算得到一平均距离作为在该区域中人与摄像装置2之间的距离。如：当人A到摄像装置2之间的距离为8m，人B到摄像装置2之间的距离为10m，人C到摄像装置2之间的距离为12m，则该侦测模块12确定在该区域中该些人到摄像装置2之间的距离为平均距离10m。When the detection module 12 detects that there is a person in the determined area, determine the distance between the person and the camera 2 in the area, wherein, when the detection module 12 detects that there is a person in the determined area Multiple persons respectively determine the distance between each person and the camera device 2 , and calculate an average distance as the distance between the person and the camera device 2 in the area. For example: when the distance between person A and camera 2 is 8m, the distance between person B and camera 2 is 10m, and the distance between person C and camera 2 is 12m, then the detection module 12 determines that The average distance between these people and the camera 2 in this area is 10m.
该执行模块13用于根据该确定的该区域中人到摄像装置2之间的距离确定该距离所在的距离范围，并根据该存储器30存储的距离范围与显示内容的对应关系获取该确定的距离范围所对应的显示内容，并控制该至少一显示单元40显示该获取的显示内容。从而根据该人到摄像装置2之间的距离的不同，而控制该至少一显示单元40显示不同的显示内容，从而达到更好的宣传效果。如当人到摄像装置2之间的距离为10m时，该执行模块13控制该至少一显示单元40显示“百货限时特价8/5-8/10，家电、服饰满五千再折扣；化妆品五折起”。The execution module 13 is used to determine the distance range of the distance according to the determined distance between the person in the area and the camera 2, and obtain the determined distance according to the correspondence between the distance range stored in the memory 30 and the display content display content corresponding to the range, and control the at least one display unit 40 to display the acquired display content. Therefore, according to the difference in the distance between the person and the camera device 2 , the at least one display unit 40 is controlled to display different display contents, so as to achieve a better publicity effect. For example, when the distance between the person and the camera 2 is 10m, the execution module 13 controls the at least one display unit 40 to display "Department store limited-time special price 8/5-8/10, home appliances, clothing, and more than 5,000 discounts; cosmetics 5" Fold up".
在本实施方式中，该数字展示看板1还连接于一音频播放装置3，该存储器30中还存储有对应于显示内容的音频文件。该执行模块13还在获取显示内容后，获取对应于显示内容的音频文件，并控制该音频播放装置3播放该获取的音频文件。In this embodiment, the digital display board 1 is also connected to an audio playback device 3, and the memory 30 also stores audio files corresponding to the displayed content. The executing module 13 also acquires an audio file corresponding to the displayed content after acquiring the displayed content, and controls the audio playing device 3 to play the acquired audio file.
在本实施方式中，该每个至少一显示单元40包括一第一显示区域41和一第二显示区域42。该存储器30中还存储有一虚拟物体的三维模型及摄取的图像与实际物体的比例(如1∶100)。在本实施方式中，该虚拟物体为一人体模型。在初始状态下，该虚拟物体面向前方。该数字告示系统10还包括一影像分析模块14，该影像分析模块14用于确定该确定的区域中的人相对于该摄像装置2的方向和角度，并根据该确定的人相对于该摄像装置2的方向和角度控制该虚拟物体朝相应的方向转动相应的角度，使得该人体模型正对前面的人，从而使得在该电子看板前的人有人体模型对着自己说话的感觉，增加广告宣传的效果。In this embodiment, each of the at least one display unit 40 includes a first display area 41 and a second display area 42 . The memory 30 also stores a three-dimensional model of a virtual object and a ratio (such as 1:100) of the captured image to the actual object. In this embodiment, the virtual object is a human body model. In an initial state, the virtual object faces forward. The digital signage system 10 also includes an image analysis module 14, the image analysis module 14 is used to determine the direction and angle of the person in the determined area relative to the camera device 2, and according to the direction and angle of the determined person relative to the camera device 2 2. Control the direction and angle of the virtual object to turn the corresponding angle in the corresponding direction, so that the mannequin is facing the person in front, so that the person in front of the electronic billboard has the feeling that the mannequin is talking to himself, increasing advertising Effect.
具体的，该影像分析模块14确定在该确定的区域中的该每个人在图像中的坐标，计算该些人的平均坐标，计算在图像中该些人的平均坐标与图像中心点的距离。如图3所示，该些人的平均坐标与图像中心点的距离在实际中对应为，在与摄像装置2的镜头延长线垂直的一竖直平面中，该摄像装置2与人在该竖直平面上的正投影所形成的点的距离。该影像分析模块14还用于根据该存储器30中存储的摄取的图像与实际物体的比例来确定在实际中该摄像装置2与人在该竖直平面上的正投影所形成的点的距离(以下称为第一距离d1)。显然，该确定的人与摄像装置2之间的距离(以下称为第二距离d2)构成了直角三角形的一条斜边的边长，该第一距离d1构成了直角三角形的一条直角边的边长。Specifically, the image analysis module 14 determines the coordinates of each person in the determined area in the image, calculates the average coordinates of these people, and calculates the distance between the average coordinates of these people in the image and the center point of the image. As shown in Figure 3, the distance between the average coordinates of these people and the center point of the image actually corresponds to, in a vertical plane perpendicular to the lens extension line of the camera device 2, the distance between the camera device 2 and the people in the vertical plane The distance of a point formed by an orthographic projection on a rectilinear plane. The image analysis module 14 is also used to determine the distance ( Hereinafter referred to as the first distance d1). Obviously, the determined distance between the person and the camera 2 (hereinafter referred to as the second distance d2) constitutes the side length of a hypotenuse of a right triangle, and the first distance d1 constitutes the side of a right angle side of a right triangle long.
该影像分析模块根据公式夹角X＝arcsin(d1/d2)来确定该确定的区域中的人相对于该摄像装置2的方向和角度，并根据该确定的人相对于该摄像装置2的方向和角度控制该虚拟物体朝相应的方向转动相应的角度。如：当人的平均坐标在图像中心的右上方，人的平均坐标与图像中心的距离为5cm，该摄取的图像与实际物体的比例为1∶100，人与摄像装置2之间的平均距离为10m，则该影像分析模块14确定该虚拟物体应转动的方向为右方，且转动的角度为30度。The image analysis module determines the direction and angle of the person in the determined area relative to the camera 2 according to the formula angle X=arcsin(d1/d2), and according to the determined direction of the person relative to the camera 2 and Angle controls the virtual object to rotate the corresponding angle in the corresponding direction. For example: when the average coordinates of a person are at the upper right of the center of the image, the distance between the average coordinates of the person and the center of the image is 5cm, the ratio of the captured image to the actual object is 1:100, and the average distance between the person and the camera device 2 is 10m, then the image analysis module 14 determines that the direction in which the virtual object should rotate is right, and the rotation angle is 30 degrees.
该执行模块13用于控制该至少一显示单元40在该第一显示区域41中显示该获取的显示内容，在该第二显示区域42中显示该转动后的虚拟物体(如图4所示)，从而使得展示看板中的虚拟物体不断随着浏览者移动方向进行调整，从而持续面对浏览者进行展示说明，增加真实感。The execution module 13 is used to control the at least one display unit 40 to display the acquired display content in the first display area 41, and display the rotated virtual object in the second display area 42 (as shown in FIG. 4 ). , so that the virtual objects in the display board are constantly adjusted with the viewer's moving direction, so as to continuously display and explain to the viewer, increasing the sense of reality.
