提出了一种基于计算机视觉的车辆速度检测方法 ,通过对图像中提取的车辆和场景信息分析来有效地检测车辆速度 ,只需要 2台CCDTV摄像机可完成双向四车道高速公路或城市道路上车辆的速度检测 .实验结果表明 :车辆速度检测的正确率达 92 % ,并具有满意的实时特性 A vehicle speed detection method based on computer vision is proposed, which can effectively detect the vehicle speed by analyzing the extracted vehicles and scene information in the image. Only two CCDTV cameras are required to complete the bidirectional four-lane expressway or the vehicle on the urban road Speed ​​test.The experimental results show that the correct speed of vehicle detection is up to 92% and has satisfactory real-time characteristics
