Single camera vehicles speed measurement

Image and video processing techniques are one of the commonly used methods for traffics monitoring. This paper investigates the image processing techniques based vehicles speed measurement issue using only a fixed single camera. Therefore, a geometrical calculation based method is proposed. Based on this method, first a moving vehicle is detected in a video background and then the vehicle speed is estimated based on some geometrical calculations. A comparison is made between this method and two other same case vehicles speed measurement methods for evaluation. The simulations results on 160×112 pixels real recorded video images shows the average vehicles speed error less than %10.
