摘　　要：针对摄像机视野分界线是一种有效地解决多摄像机人体跟踪目标交接问题的工具,提出了一种基于同步视频的摄像机视野分界线快速自动生成算法,利用视野分界线和目标中心到视野分界线的距离实现多摄像机之间的目标交接。该算法不依赖摄像机的标定信息和目标颜色信息。为验证该算法的有效性,设计搭建了一个室内视觉有重叠区域的多摄像机人体跟踪系统。实验结果表明,该算法具有易实现、实时、准确率高的优点。As camera Field of View （FOV） line was an efficient tool to resolve target handoff problem in human tracking with multiple cameras. A new algorithm for fast automatic generating camera FOV line based on synchronized video was presented. Using camera FOV line and the distance between target and camera FOV, the right correspondence could be gotten. The algorithm was independent on camera＇s calibration and target＇ s color information. To verify the algorithm, the anther sotupod a system with three cameras with overlapping FOV to cover most of a room. Experiments indicate the algorithm is faster and easer for resolving target handoff problem with high veracity in multiple cameras human tracking system.
