Embodiment Construction

[0057] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0058] Such as figure 1 and figure 2 As shown, the pedestrian crossing intelligent traffic light supervision system based on computer vision includes a camera, a computer network cable interface and a computer image processing system. The computer image processing system is connected to the camera through the computer network cable interface; the camera is positioned by simultaneously collecting vehicle and pedestrian information. The cameras of this system are CCD cameras, and there are only two cameras, camera one 1 and camera two 2 . Two cameras are installed at both ends of the crosswalk, figure 1 The area covered by the field of view of camera 1 is between the two thick lines, and the area covered by the field of view of camera 2 is between the two thin lines. The field of view of each camera includes the waiting area on the opposite side In th...

Abstract

The invention relates to a pedestrian crosswalk intelligent traffic light monitoring system and method based on computer vision. The positioning of system cameras adopts a method for simultaneously collecting information of vehicles and pedestrians, so that the quantity of the cameras needed by the system is only two, a video on a pedestrian crosswalk acquired by a charge coupled device (CCD) camera is used as a to-be-processed target, the quantity of the pedestrians and the vehicles waiting for crossing the crosswalk can be automatically detected, a display time of a traffic light is automatically set and switched through a neural network algorithm according to the detected quantity of the pedestrians and vehicles waiting for crossing the crosswalk, so that the pedestrians and the vehicles can pass through a crossing of the crosswalk through an optimum way, and the intelligent management of a traffic system at the pedestrian crosswalk can be realized.

Description

technical field [0001] The invention relates to an intelligent system in the technical field of computer vision, in particular to a computer vision-based intelligent traffic light supervision system and method for pedestrian crossings. Background technique [0002] With the progress of urbanization and the rapid development of social economy, transportation problems are becoming more and more serious, road vehicles are crowded, traffic accidents occur frequently, and the traffic environment deteriorates. Today's road system has not been fully utilized. At some point, there are still a large number of vehicles waiting to pass without pedestrians, or a large number of pedestrians waiting to pass without vehicles. These two situations. The traffic system is like a chain, and intersections such as pedestrian crossings are a part of the chain. Any problem in any link will affect the function of the entire chain. Therefore, in order to make full use of the road system and realize...
