视频监控技术为重要场所安全防护提供了可靠保障,随着视频监控系统应用领域的扩大,视频监控技术得到了迅速发展。首先对视频监控技术的发展历程分三个阶段进行了概括,其次对视频监控中的关键技术的现状和发展方向进行了分析,其中重点描述了运动检测中的主流方法——背景差方法,目标跟踪中用于解决遮挡问题的合并-分裂方法和直接-穿透方法,最后提出了视频监控技术在实际应用中所面临的问题。
The technology of video surveillance enhances the secure reliability in important situations and it is developed rapidly with the expansion of its application in various areas. This paper reviews its history by three stages at first, then analyzes its status at present and development trends by focusing on the background subtraction techniques that are commonly used in motion detection, the merge- split approach and the straight- through approach that deal with occlusion in target tracking, presents the most urgent issues in its application in conclusion.
