This article presents a new method based on video images to measure the speed of vehicles. The working principle is taking two instantaneous tandem photographs. Then based on the location of the vehicle and CCD, with reference to the advance calibration lines, we can obtain speed of vehicle. Further, this paper analyses two measurement errors, and discusses how to choose the picture filming location. Simulations verify the effectiveness of the given method.
