Abstract： |
The invention relates to a digital video camera based red light running detection system and method, wherein a high-definition digital video camera is used for road monitoring. The red light running detection system mainly comprises front end devices and ground devices. A digital video camera (1) among the front end devices is used for collecting crossing images, and the images are transmitted to an industrial control computer (9) through a front end optical terminal (2), optical fiber (6) and a ground optical terminal (10) as one of the ground devices in turn. The industrial control computer is used for identifying behaviors of a vehicle in accordance with the set detection parameters and present signal light status. The computer is also used for extracting information of the red light running vehicle, acquiring information of the vehicle license plate, and storing and managing the image sequence or video flow before and after red light running and the information of the license plate. The invention needs only a high-definition digital video camera for monitoring double lane vehicles in a same direction, and no separate panoramic video camera is needed for photographing the signal light status, so the detection system makes violation identification more powerful. |
