摘要
为实现多目标的精确跟踪,提出一种基于视频客流量的跟踪计数方法。利用图像差分法提取运动目标,对差分图像进行形态学处理,使用连通域分析创建人体结点,得到目标的形心,采用向前优先搜索像素点的原则搜索下一帧图像的所有像素点,通过搜索到的像素点确定目标的新中心位置,根据目标中心与计数线的关系进行计数。实验结果表明,该方法简单可行,统计数据具有较高的正确率。
In order to solve the problem about multitarget tracking,this paper proposes a new video based traffic tracking counting method.The frame difference method is used to extract the moving target and the image needs morphological processing.Connected domain analysis is applied to create the human node and get the node’s centroid.According to the nodes’ centroids which are created in the list,first search forward is used.All target pixels are searched in the next frame which are used to determine the new position of the object in the video.Experimental results show that the method is simple and feasible,and achieves statistical data with high accuracy.
