摘　　要：A stereo matching algorithm based on the epipolar line constraint is designed to meet the real-time and the accuracy requirements. The algorithm is applied to photodynamic therapy binocular surveillance system for port wine stain （PWS） when it monitors the position of the treatment region. The corner matching based on Hu moments is used to calculate the fundamental matrix of the binocular vision system. Experimental results are in agreement with the theoretical calculation.针对激光治疗鲜红斑痣手术机器人双目视觉系统在监测治疗区域的空间位置时立体匹配的实时性和准确性要求,提出了一种基于极线引导的立体匹配算法。采用基于角点的Hu矩匹配,计算双目视觉系统的基本矩阵。实验结果与计算结果相符。
