基于位置特征的运动行人检测与跟踪方法

针对在静态背景视频中行人检测和跟踪时受行人运动状态影响较大,容易产生误识别,提出了一种基于位置特征的运动行人检测与跟踪方法.检测阶段得到运动行人的二值化差分图后,引入水平融合值、垂直融合值将满足融合要求的非连通区域外接矩形融合得到一个新矩形,以新矩形及其中心作为行人的位置特征,对行人进行检测与跟踪.用该方法跟踪行人视频中的两个行人,跟踪准确率分别为98%与95%.

A method of detecting and tracking moving pedestrians based on position features

In this paper, a method of detecting and tracking moving pedestrians is studied,based on position features in static scenes, to solve problem of fluctuated image caused by moving that can easily resulted in false identification. Firstly getting the binary image segmentation of moving pedes-trian during the process of tracking, then introducing horizontal merging value, vertical merging val-ue to merge the contour-rectangle of some separated areas, lastly taking the new rectangle and its center as the position character of moving pedestrian to detect and track moving pedestri-an. Experimental results of two moving pedestrians' scenes show that 98% of one pedestrian can be detected and tracked and the other is 95%.
