The invention relates to the field of computer vision, in particular to a vehicle speed detection and collision early warning method, electronic equipment and a vehicle early warning system. The invention provides a vehicle speed detection method, which comprises the following steps of: acquiring a monitoring video of a road, and extracting continuous multi-frame images in the monitoring video; and identifying the vehicle in the multi-frame image, and establishing a driving track of the target vehicle. And obtaining image position coordinates of the target vehicle in each frame of image. And obtaining world position coordinates of the target vehicle in the real world according to the image position coordinates. And calculating the moving distance of the target vehicle in the real world in every two adjacent frames of images in the multiple frames of images according to the world position coordinates. According to the driving distance of the target vehicle in the real world and the frame rate of the monitoring video, the speed of the target vehicle in the current frame is calculated, and the driving distance is obtained according to the moving distance.
本公开涉及计算机视觉领域,尤其涉及一种车辆速度检测、撞车预警方法及电子设备和车辆预警系统;提供一种车辆速度检测方法,包括:获取道路的监控视频,提取监控视频中连续的多帧图像。对多帧图像中的车辆进行识别,建立目标车辆的行车轨迹。获取目标车辆在每帧图像中的图像位置坐标。根据图像位置坐标,得到目标车辆在现实世界中的世界位置坐标。根据世界位置坐标,计算多帧图像中的每相邻两帧图像中,目标车辆在现实世界中的移动距离。根据目标车辆在现实世界中的行驶距离,以及监控视频的帧率,计算目标车辆在当前帧的速度,其中,行驶距离根据移动距离得到。
