摘　　要：针对视频交通流的特点,在总结以往视频车辆检测方法的基础上,提出了一种改善背景的更新方法,并着重对车流量统计和车速计算算法的实现进行了介绍。最后给出了实现结果并讨论了提高检测数据准确性的措施。Considering the characteristics of traffic flow and on the basic of the other methods for video traffic detection, this paper introduced an improved method of background updating. Then, the paper provided a detailed description of vehicle flow statistics and speed calculation, and gave the ways of realization. Finally, the paper presented the results of the system implementation and put forward some suggestions in improving the system＇s veracity performance.
