摘　　要：介绍了在智能交通系统中的实时图像处理技术,论述了视频车辆流检测的设计思想,重点介绍了智能交通的核心——车辆检测。根据环境的不同提出不同的检测办法,即白天利用图像序列进行差分运算和夜间利用数学形态学方法。实验数据表明,白天车辆正确识别率在92 %以上,而夜间正确率在80 %左右。It presents a real time image processing technology for use in intelligent transportation system, and introduces design of vehicle measuring based on video. The estimation of the vehicle flow measuring is the core of ITS, on daytime with temporal difference and on nighttime with mathematical morphology based on different light conditions. A great number of experiments indicates that the correct recognition rate of this system reaches up to 92% on daytime and about 80% on nighttime.
