摘要：In a video surveillance network system constructed by multi-cameras, when a target accesses to one camera's FOV(field of vision) from another's, it is a key problem in this system to schedule the cameras correctly and to achieve reliable target handoff. In this paper, we propose a novel target handoff algorithm and scheduling strategy for network-based multi-camera in a target relay tracking system. In the algorithm, the moment and the location of target handoff are determined by real-time background estimation, and the rapid scheduling of relay camera is achieved using the scheduling algorithm based on multi-camera network topology model formed through network connection between cameras in large and complex scene. The target features are passed to the relay camera which locating and tracking the target successively. Experimental results show relay camera scheduling and target handoff can be accomplished rapidly and accurately, and very good results have been obtained. © 2013 Binary Information Press.
