Speed Determination Using Video Recording

The wide use of surveillance video equipment has provided important clues for investigation and identification of various cases. The technique of using clear video images for close-range photogrammetry, moving objects recognition and tracking is quite mature; but the technique of using wide-angle, low-pixel video surveillance video for estimation of vehicle speed is not yet established. According to general calculation methods and basic principles of computer vision, the vehicle speed in different cases of traffic accidents is studied using public surveillance video recordings.
