中文摘要：

针对视频传感器观测被动的问题,结合视频传感器和传感网的特点,设计了传感网环境下视频传感器在线规划框架。该框架采用面向服务的体系架构（SOA）,包含资源层、资源服务层、规划服务层和应用层四个层,各层之间采用标准的网络通信协议进行通信。实现了视频传感器在线规划原型系统,并以视频监控签到为应用场景进行了在线规划实验。实验结果表明：该框架对于实现视频传感器主动和按需观测是可行且有效的。

英文摘要：

To solve the problem of passive observation of a video sensor, an online planning framework of a video sensor within the context of Sensor Web was proposed considering the characteristics of a video sensor and the Sensor Web. Service- oriented Architecture （SOA） was adopted for the proposed framework which included four layers, i.e., application layer, planning service layer, resource service layer and resource layer, communicating through standard network protocols. A video sensor online planning prototype system was realized and the surveillance of work attendance was used as a scenario for online planning experiment of a video sensor which demonstrates that the proposed framework is feasible and effective in realizing active and on-demand observation of a video sensor.
