摘　　要：基于自组织视频传感网络的目标跟踪方法利用节点的分布式观测能力,实现目标的精确跟踪。在研究视频节点观测投射模型和通信模型的基础上,提出一种基于移动Sink的自组织视频传感网络目标跟踪算法MSTTA。该算法包括感知信息聚合和目标位置评估两个部分,利用节点分类机制周期性地更新网络拓扑以适应Sink位置的变化,根据目标运动状态预测目标位置的评估节点小组。仿真实验表明,MSTTA算法能够适应Sink移动带来的网络拓扑变化,具有较高的目标跟踪精度。Target tracking based on Ad- hoc Camera Sensor Networks using the distributing observed function ofnodes to track targets accurately. Based on the model analysis of camera sensor perspective projection and communi-cation,a Mobile Sink based Target Tracking algorithm for Ad-hoc Camera Sensor Networks（MSTTA）is proposed.There are two parts in the algorithm：sensor data gathering and target location evaluating,which using nodes classify-ing scheme to update the network topology periodically for the change of Sink＇s location,and forecasting target loca-tion evaluating group of nodes according to the target＇s status of motion. Experiment results show that the proposedMSTTA algorithm can adapt to the change of network topology caused by mobile Sink,and tracks the target accurately.
