The invention relates to the technical field of image recognition, and particularly discloses a traffic signal lamp operation abnormity judgment method based on a road monitoring video, which comprises the following steps: acquiring a signal lamp image of a current intersection; identifying the extinguished signal lamp from the signal lamp image; when other signal lamps in the same group of signal lamps are not turned on, determining that the turned-off signal lamp has a fault that the signal lamp should be turned on or not turned on; when other signal lamps are lightened, judging whether the traffic state in the direction of the group of signal lamps at the current intersection is abnormal or not; if so, determining that the other signal lamps have a normally-on unchanged fault; if not, acquiring the traffic state of the current intersection in other directions; when there is a vehicle queue in one direction of the current intersection and there is no vehicle queue in the other direction, tracking the vehicle passing condition in the whole green light period in the non-queuing direction; and after the green light in the non-queuing direction is turned on for a period of time, the queuing vehicles in the non-queuing direction are emptied, and the condition of unreasonable timing of the signal lamps at the current intersection is determined. According to the invention, abnormal operation of the road traffic signal lamp can be found in time, and traffic accidents caused by abnormal operation of the signal lamp are avoided.

    本发明涉及图像识别技术领域,具体公开了一种基于道路监控视频的交通信号灯运行异常判别方法,包括:获取当前路口的信号灯图像;从信号灯图像中识别出熄灭的信号灯;当同一组信号灯中的其他信号灯未点亮时,确定出该熄灭的信号灯存在应亮未亮故障;当其他信号灯点亮时,判断当前路口的该组信号灯方向的交通状态是否异常;若异常,则确定出该其他信号灯存在常亮不变故障;若不异常,则获取当前路口的其他方向的交通状态;当当前路口的一个方向存在车辆排队而另一个方向未存在车辆排队时,对未排队方向整个绿灯时段的车辆通行情况进行跟踪;当未排队方向的绿灯点亮一段时间后,未排队方向的排队车辆清空,则确定出当前路口的信号灯存在配时不合理情况。本发明能够及时发现道路交通信号灯运行异常,避免由信号灯运行异常引发的交通事故。
