摘要 视频监控已经被广泛应用于各种场景,为安全防卫提供了有效信息。综述视频传感器网络中覆盖问题的相关研究。视频传感器网络具有有向传感器网络的一般特征。考虑到监测对象通常有面部朝向属性,视频传感器网络的感知模型又不同于一般的有向传感器网络的感知模型。根据感知模型是否考虑监测目标的朝向,分别介绍视频传感器网络中的点覆盖、区域覆盖和栅栏覆盖问题的典型算法。此外,讨论了目前研究存在的问题以及未来可能的研究方向。 Video monitoring has been applied to various occasions to provide efficient information for safe guarding. In this paper, the coverage problems in Visual Sensor Network （VSN） were surveyed. VSN has the characteristics as directional sensor network. However, if take the facing direction of monitoring target into account, VSN is different from the ordinary directional sensor network. According to whether considering the facing direction of monitoring target in the sensor model, the works on coverage of VSN including target coverage, area coverage and barrier coverage were introduced in this paper respectively. Finally, the current problems and future research direction were discussed.
