Therefore, the traffic police can remotely acquire the moving speed of the vehicle, and waste of police resources is reduced. In addition, the user equipment inputs the image frame of the vehicle movement into the preset algorithm model, so that the movement speed of the vehicle is obtained, and the accuracy of the obtained image frame and the accuracy of the preset algorithm model are not affected by weather, so that the accuracy of the obtained movement speed of the vehicle can be ensured even under the condition of bad weather.
