The invention relates to the technical field of computer vision, and discloses a vehicle speed measurement method and device based on a road monitoring video, and electronic equipment. The method comprises the following steps: determining at least two target images from a monitoring video, and extracting vehicle position information and corresponding vehicle identifiers in a target speed measurement rectangular area of the target images; calculating at least two pieces of corresponding target vehicle position information in the at least two target images by using a perspective transformation matrix to obtain at least two pieces of standard position information; according to the at least two pieces of standard position information, the standard speed measurement area and the actual speed measurement rectangular area, actual displacement is obtained; and obtaining vehicle speed information corresponding to the vehicle identification information according to the actual displacement and the video frame rate of the monitoring video. Camera calibration work based on monitoring video speed measurement is reduced; real-time speed measurement and vehicle information extraction and binding can be realized; the speed measurement scene is less limited, and the cost is low.

    本申请涉及计算机视觉技术领域,公开了一种基于道路监控视频的车辆测速方法、装置以及电子设备。所述方法包括从监控视频中确定至少两张目标图像,并提取所述目标图像的目标测速矩形区域中的车辆位置信息以及对应的车辆标识;利用透视变换矩阵计算所述至少两张目标图像中对应的至少两个目标车辆位置信息,得到至少两个标准位置信息;根据至少两个所述标准位置信息、所述标准测速区域以及所述实际测速矩形区域,获取实际位移;根据所述实际位移以及所述监控视频的视频帧率,获得所述车辆标识信息对应的车速信息。减少了基于监控视频测速的相机标定工作;可以实现实时测速和车辆信息提取并绑定;对测速场景的限制少,成本较低。
