基于静态场景下的单目标徘徊检测及跟踪方法

Method of single-object hovering detection and tracking based on static background

提出了一种单目标徘徊检测及跟踪方法。该方法能够有效地对防区内有徘徊行为的对象进行跟踪报警,简单实现了监控方式由事后取证到提前预防的转变。目标的跟踪是通过背景差分方法检测出运动目标,然后利用矩形逼近目标轮廓,并把该矩形作为目标跟踪时的跟踪框,最后利用Camshift算法弥补背景差分方法的不足。实验结果表明,本方法能满足单目标徘徊跟踪的基本要求。

This paper provides a method of single-object hovering detection and tracking.This method can track hovering object efficiently in the defence area and realize the change of monitor mode from obtaining evidence to prevent something happen.Object tracking utilizes background subtraction to detect object and approach object contour with rectangle which is also an object’s tracking box.Furthermore,Camshift algorithm is used to make up the shortage of background subtraction method.The experiment results show that this method can meet basic requirements of single-object hovering tracking.
