摘　　要：本系统利用三帧差法识别运动目标,质心法标定运动目标的质心,利用双摄像机交叉视野的几何约束,通过求解单应矩阵实现两个摄像机之间的目标匹配,实现运动目标的连续跟踪。和单摄像机跟踪相比,双摄像机跟踪的视野范围大,可以对目标持续跟踪,在一定程度上解决目标遮挡、场景混乱等问题。经过优化系统每秒可以处理30帧图像。跟踪的检测准确率达到92.1%,取得了较好的跟踪效果。The system uses the three-image difference method to identify moving targets, and the centroid method to demarcate the target centroid. It achieves the goal of target matching between two cameras by solving the homography matrix based on the geometric constraints of the double cross-camera vision, thus continuously tracking and monitoring moving goals. Com- pared with the single camera tracking, the two-camera tracking with a lager view can track tar- gets continuously by solving the problems of temporal occlusion and scene confusion to some extent. After optimization, the system can deal with 30 frames image per second. Experimen- tal results show that the detection accuracy rate of object tracking achieves 92.1% and it ob- tains a good tracking performance.
