多运动目标探测标记及跟踪

Detection labeling and tracking of multi-moving targets

针对跟踪系统对多目标跟踪以及对实时性的要求,给出了一种基于中心点和面积特征匹配的多运动目标探测标记及跟踪方法.该方法利用对多运动目标检测后的二值图像进行了连通成分标记,提出了一种新的探测搜索标记法,赋予不同连通区域不同的数字来区分,通过四连通区域法来实现.由运动目标的4个顶点来确定中心点,通过面积及中心点距离从而进一步去匹配,最后根据标记结果在原图像中准确地框定了各运动目标,从而实现对运动目标的跟踪.采用上述算法,对车辆视频进行了跟踪,取得了较好的实验结果,跟踪实验结果验证了该方法具有很好的实时性.

A real-time multi-moving target detection labeling and tracking method of moving object based on the center point and areag characteristic matching was given in the light of multi-target tracking and real-time requirements of the tracking system. After detection of the multi-moving targets, the consecutive area of the binary image is labeled. A new detection labeling method is presented by labeling the four consecutive binary images with numbers, which are acquired by the detection of multi-moving targets. The center point can be obtained by four vertexes of the moving target, and further matching can be done by measuring the areas and central distance of the moving targets. Finally, the moving targets can be traced by the labeling results of those framed moving targets. The video of vehicles was processed by the algorithm. The experimental results show that the method is effective.
