摘　　要：交通路口监控系统因其能够主动收集分析数据,并实时检测进行预设处理,随着该技术的不断成熟,针对不同环境条件产生的多种图像处理方法。文中对其中两种方法:帧差法和背景差分法,在一般情况下的优劣性进行分析研究,通过模拟仿真得到帧差法要比背景差分法准确性更高。The new monitoring system of traffic crossing has attracted wide public concern for its initiative to collect and analyze data to design processing and real-time detection.With the development of technology,scientists have created a lot of image processing methods according for different environments.This paper aims at two main methods：the frame difference and background difference methods.We analyze their general advantages and disadvantages.Computer simulation shows that the frame difference is better than the background difference method.
