| Abstract: | A method of detecting vehicle speed by image processing was presented aiming at the speed detection in the traffic control. Virtual loops were defined on the image sequence extracted from the CCD cameras. By the use of the block-based motion estimation techniques, the motion vectors of the virtual loops can be acquired which may represent the speed of the passing vehicles. The experiments indicated that the proposed method was effective in detecting vehicle speed. |
