The invention relates to the technical field of video processing, and discloses a moving speed measurement method and system, electronic equipment and a readable storage medium. The image coordinate points of the to-be-measured target in the image are converted into the geographic coordinate points of the real world through the perspective transformation matrix, then the real moving speed of the to-be-measured target is determined, and compared with the mode that the real moving speed is estimated through the pixel moving distance, image deformation caused by the perspective principle is reduced, and the accuracy of moving speed measurement is improved.
本发明涉及视频处理技术领域,公开了一种移动速度测量方法、系统、电子设备及可读存储介质,该方法根据地理坐标矩阵和图像坐标矩阵获取透视变换矩阵,通过透视变换矩阵将待测目标在图像中的图像坐标点转换为现实世界的地理坐标点,进而确定待测目标的现实移动速度,相较于通过像素移动距离估计现实移动速度,减少由于透视原理造成的图像形变,提高移动速度测量的准确性。
