提出了一种基于双目立体相机的实时集成成像拍摄系统。不同于采用传统的摄像机阵列,该系统采用双目相机对三维场景进行拍摄,有效地简化了集成成像拍摄系统的结构。该系统首先利用双目相机获取三维场景的左右视差图,然后上传到图形处理器生成三维场景的高分辨率深度图,之后利用深度图和彩色纹理图在图形处理器中并行生成新视点视差图像,并利用像素映射算法生成高分辨率微图像阵列,实现实时的集成成像显示。实验中系统获取的深度图像素数目是微软Kinect2获取深度图像素数目的 4.25倍,当系统运行在1 920 pixel×1 080 pixel、9×9视点数的环境下,可实现三维场景的实时拍摄与显示,实验结果证明了所提系统的可行性。
A real-time integrated imaging system based on binocular stereo camera is proposed. Different from the traditional camera array, the system uses a binocular camera to shoot the three-dimensional scene, which effectively simplifies the structure of the integrated imaging shooting system. The system first uses the binocular camera to acquire the left and right disparity images of the three-dimensional scene and then uploads them to the graphics processor to generate the high-resolution depth map of the three-dimensional scene, and then uses the depth map and the color texture map to generate new viewpoint disparity images in parallel in the graphics processor , And use the pixel mapping algorithm to generate high-resolution micro-image array, real-time integrated imaging display. In the experiment, the number of depth pixels obtained by the system is 4.25 times that of the Kinect2 acquired by the Microsoft Kinect2. When the system is operated at a resolution of 1 920 pixel × 1 080 pixel and 9 × 9 viewpoints, real-time shooting and displaying of the 3D scene can be realized The experimental results prove the feasibility of the proposed system.
