摘　　要：基于方向可调感知模型,本文提出一种基于虚拟势场的路径覆盖增强算法(PFPCE).将待解决问题转化为质心点-运动轨迹点,质心点-质心点间虚拟力作用情况.仿真结果说明:PFPCE算法以较小代价获得视频传感器网络对路径的充分高效覆盖.Based on the adjustable direction sensing model, we propose a Potential Field based Path Coverage Enhancement algorithm （PFPCE）.This algorithm transports the pending issue into the study on the force laws to govern the interaction between centroid-centroid and centroid-trackpoint, in order to maximize path coverage while minimizing the overlapping sensing area among multiple neighboring video nodes, thus achieve better path coverage rate. Simulation results show the PFPCE algorithm can obtain effective path coverage with small cost.
