| 摘 要： | 提出了一种改进的快速立体匹配算法。对于双目视觉系统采集的2幅图像,首先采用区域匹配算法进行初始快速立体匹配,再采用左右一致性检验剔除误匹配点,得到立体匹配的初始视差图。然后将初始视差作为图割法构图的限制条件,对初始视差图进行二值分割。最后对分割获得的前景区域和背景区域施加不同的限制,并通过修正能量函数,使构图网络大大减小,从而进一步提高了匹配速度。试验结果表明,该算法既提高了立体匹配速度,又保证了匹配精度。

| Abstract: | An Improved fast stereo matching algorithm is presented in this paper. An area matching algorithm is used to perform stereo matching for two images captured from a stereo-vision system. And left-right conformity verification is adopted to further eliminate those mistaken matching points. Then the initial disparity map is segmented by an optimal threshold segmentation algorithm, and the background and foreground regions are obtained. Then the different limits for the background and foreground regions are used as a constraint condition of graph cuts matching algorithm and that reduce the scale of graphs heavily. The experimental results demonstrate that the proposed algorithm can improve stereo matching speed while keeping disparity precision. |
