摘要：AbstractIn order to reduce the effect on vehicles in the major road and shorten the waiting time of pedestrians, an adaptive pedestrians crossing signal control system was designed in this paper. The system was composed of capturing units of video and image sequence, control units and display units. Video and image sequences were real-timely acquired by capturing units. The main task of the control units was to adaptively calculate the waiting area and the waiting time of pedestrians. The display units controlled the status changes of signal light based on the processing results. It is pointed that the background of scene can be reconstructed correctly when the pedestrians begin to pass the street, and the total number of pedestrians and the waiting time can be detected effectively. The results indicate that adaptive pedestrian crossing system can control the signal status of pedestrian. Finally, some of the possible extensions of this technique are discussed.
