我们描述了一个实时立体视觉系统，能够以30 fps的速度处理高分辨率（100万像素或更多）图像，视差范围为100像素或更多。该系统具有与每个相机相关联的快速纠偏模块，该模块使用查找表方法在一个步骤中消除镜头畸变和纠正相机错位。校正后的对齐图像通过一个模块，该模块生成视差和遮挡图，延迟为两个相机扫描线间隔。该模块实现了对称动态规划立体（SDPS）算法的一个版本，该算法具有小而紧凑的硬件实现，允许实例化许多副本以适应大的视差范围。从我们实验室拍摄的视频快照表明，该系统可以实时生成有效的深度图。SDPS算法生成的遮挡图清晰地勾勒出场景中不同的物体，为快速将场景分割成感兴趣的物体提供了强大的工具。
We describe a real time stereo vision system capable of processing high resolution (1Mpixel or more) images at 30 fps with disparity ranges of 100 pixels or more. This system has a fast rectification module associated with each camera which uses a look up table approach to remove lens distortion and correct camera misalignment in a single step. The corrected, aligned images are passed through a module which generates disparity and occlusion maps with a latency of two camera scan line intervals. This module implements a version of the Symmetric Dynamic Programming Stereo (SDPS) algorithm which has a small, compact hardware realization, permitting many copies to be instantiated to accommodate large disparity ranges. Snapshots from videos taken in our laboratory demonstrate that the system can produce effective depth maps in real time. The occlusion maps that the SDPS algorithm produces clearly outline distinct objects in scenes and present a powerful tool for segmenting scenes rapidly into objects of interest.
