一种结合流媒体技术的无线视频监控网格

Approach to Building a Wireless Video Surveillance Grid Using Streaming Media Technology

现代社会对无线视频监控的需求日益增长,提出一种新型的无线视频监控网格设计方案.与传统监控网络相比,该方案采用网格技术与流媒体技术,在监控资源动态共享、监控问题协同解决、监控画面实时点播等方面有显著优势.本文提出该方案的总体设计与中间件设计,给出一个典型的监控预警应用实例.仿真实验表明,该方案在可疑事件捕获率、存储开销、报警延迟等方面明显优于传统方案.

To meet the increasingly growing requirement on wireless surveillance for social security,we propose an approach to constructing a wireless surveillance grid using streaming media technology.Compared with traditional surveillance networks,our approach combines grid technology and streaming media technology,and is more suitable for surveillance applications which require dynamic resource sharing,collaborative problem solving,and real time video-on-demand.This paper gives the overall design and the middle-ware design of our surveillance grid,and presents a typical application based on this grid.The simulation results reveal that our approach outperforms traditional surveillance networks in terms of suspicious object detection rate,storage cost,and alarm delay.
