The embodiment of the invention provides a vehicle running speed detection method, device and system and electronic equipment. The method comprises the steps of: acquiring a first snapshot image of atarget vehicle at a speed measurement starting point and a second snapshot image of the target vehicle at a speed measurement terminal point; performing image recognition on the first snapshot image and the second snapshot image, and determining a first distance between the target vehicle and a pre-calibrated speed measurement starting line and a second distance between the target vehicle and a pre-calibrated speed measurement ending line; determining the actual driving distance of the target vehicle based on the first distance, the second distance and the distance between the speed measurement starting line and the speed measurement ending line; and determining the driving speed of the target vehicle according to the actual driving distance and the driving time. Based on the first distance, the second distance and the distance between the speed measurement starting line and the speed measurement ending line, the actual driving distance of the target vehicle can be accurately determined, and the accuracy of the detected vehicle driving speed is greatly improved.
本发明实施例提供了一种车辆行驶速度的检测方法、装置、系统及电子设备,方法包括:获取目标车辆在测速起点的第一抓拍图像和在测速终点的第二抓拍图像;对第一抓拍图像和第二抓拍图像进行图像识别,确定目标车辆与预先标定的测速起始线之间的第一距离以及目标车辆与预先标定的测速终止线之间的第二距离;基于第一距离、第二距离以及测速起始线与测速终止线之间的距离,确定目标车辆的实际行驶距离;根据实际行驶距离及行驶时间,确定目标车辆的行驶速度。由于基于第一距离、第二距离以及测速起始线与测速终止线之间的距离,所以可以准确确定目标车辆的实际行驶距离,大大提高检测得到的车辆行驶速度的准确度。
