摘要
为了解决现有的嵌入式数字视频监控系统的多路视频存储与检索的结构差异,从而严重制约视频监控系统的可复用性与引起系统I/O瓶颈问题,提出一种嵌入式数字视频监控系统通用存储与检索方案。采用组件化思想构建视频存储与视频检索模块,通过设计存储调度算法减少了I/O瓶颈问题,使用检索控制策略降低了检索拥塞。与以前的系统相比在支持多路视频存储与检索方面表现出改进的性能,同时具有更好的可重用性。
A general video storage and retrieval scheme of embedded digital video surveillance system is developed to improve the poor reusability and I/O bottle-neck of video storage and retrieval whose architecture are different each other in most existing video surveillance system. The video storage and video retrieval are implemented with embedded component-ware. This scheme reduced I/O bottle-neck by designing storage dispatch algorithm and retrieval congestion by adopting retrieval control policy. Compared with the video storage and retrieval methods of early video surveillance systems, it shows improved performance in supporting multi-channels of video storage and retrieval and better reusability.
