本文对动态景物分析的一个重要方面——动目标检测和跟踪进行了研究和搜索,其目的是研究开发相应的算法,并利用微机图象设备构成一个实用系统(从速度及价格的意义),该系统能对一些重要场所执行动目标监测与跟踪任务,一旦有目标进入所监视区域,系统能自动检测出运动目标并对其跟踪,同时报警和对现场录象. In this paper, research and search on moving target detection and tracking, an important aspect of dynamic scene analysis, are carried out. The purpose is to research and develop corresponding algorithms and use computer image equipment to form a practical system (from the meaning of speed and price) The system can perform the moving target monitoring and tracking tasks in some important places. Once the target enters the monitored area, the system can automatically detect and track the moving objects, and report the alarm and video recording to the scene at the same time.
