The invention discloses a real-time expressway vehicle speed detection method and a medium, and the method comprises the steps: directly extracting point pairs in an image from a driving video, calculating a perspective transformation matrix between the point pairs, and carrying out the fitting to obtain a vehicle driving track, the coordinates on the vehicle running track in the image are converted into the actual running coordinates of the vehicle on the road through the perspective transformation matrix, then the actual running distance of the vehicle is calculated, the vehicle running time is obtained in combination with the frame number of the collected image, and finally the running speed of the vehicle is calculated more accurately. The accuracy and reliability of vehicle speed detection are improved.

    本发明公开了一种实时高速道路车辆速度检测方法、介质,通过直接在行驶视频中提取图像中的点对,并计算点对之间的透视变换矩阵,拟合得到车辆行驶轨迹,通过透视变换矩阵将图像中车辆行驶轨迹上的坐标转换为车辆实际在道路上行驶的坐标,进而解算车辆的实际行驶距离,结合采集图像的帧数得到车辆行驶时间,最终更加准确的解算出车辆的行驶速度,提升了车辆速度检测的准确性和可靠性。
