视频监控系统中的一种信息存储新方法

New Method of Image Storage for Video Surveillance System

视频监控系统中信息存储是一个重要和有待解决的问题。本文分析了目前视频监控系统中信息存储方面存在的不足,提出了一种基于DSP和USB技术的视频监控系统信息存储方法,在软件实现上运用了动目标检测,动目标分割和图像相似度比较等算法。基于该方法的视频监控系统只记录有动目标存在时的图像,解决了视频监控系统需存储大量视频信息的问题,给DSP扩展的USBHOST接口,方便了信息的存取。

Image storage is an important part of video surveillance system, and its actual method needs to be improved. The deficiencies of the actual method of image storage in video surveillance system are analyzed, and a new method of image storage based on the DSP and USB has been proposed in this paper. Algorithm of moving object detection, image segmentation and similarity measure has been used in this system. The video surveillance system based on this method only store image, which have moving object in it. So, this method can solve the problem of heavy image storage in video surveillance system. The USB HOST interface of DSP has been designed to convenient for the access of image.
