The comparison of estimated measures for vehicles' average speed in surveillance video

According to calculation formula of vehicle speed,two methods for measuring the vehicle's speed based on the surveillance video were suggested.The first method is based on the combination of video image and field measurement.Matched with the surveillance video image,the vehicles' movement distance can be measured on field,and the movement time can be calculated from the video frame rate.The second method uses the measurement of vehicles technical parameters.While the vehicles' typical part passes the same point in the video image,the movement distance and time can be obtained from the vehicles' technical parameters and video frame rate.Two methods have been evaluated by experiments.
