The invention relates to the technical field of image recognition, and particularly discloses an expressway traffic accident staged discovery method based on a monitoring video, which comprises the following steps: acquiring the monitoring video of an expressway; when the vehicle moving tracks in the monitoring video intersect and then are static, and then accident vehicles, accident fragments and accident personnel are identified from the video, determining that the highway is the just happening stage of the traffic accident; when the number of vehicles and the number of pedestrians in the monitoring video are increased, identifying accident vehicles, accident fragments and accident personnel from the monitoring video, and determining that the expressway is the early stage of the traffic accident; and when traffic jam occurs in the monitoring video, the accident vehicle and accident fragments are identified from the video, and a vehicle avoidance track occurs in the monitoring video, it is determined that the highway is a long-time unhandled stage of the traffic accident. According to the invention, the traffic accident stage can be discriminated while the traffic accident is found, so that effective disposal is carried out, and emergency disposal resources are saved.
本发明涉及图像识别技术领域,具体公开了一种基于监控视频的高速公路交通事故分阶段发现方法,包括:获取高速公路的监控视频;当监控视频中的车辆运行轨迹交叉后静止,然后从视频中识别出事故车辆、事故碎片和事故人员时,确定出高速公路为交通事故刚刚发生阶段;当监控视频中的车辆数量和行人数量增多,且从监控视频中识别出事故车辆、事故碎片和事故人员,确定出高速公路为交通事故发生初期阶段;当监控视频中出现交通拥堵,且从视频中识别出事故车辆和事故碎片,且监控视频中出现车辆避让轨迹,确定出高速公路为交通事故发生较长时间未处置阶段。本发明能够在发现交通事故的同时判别交通事故阶段,从而进行有效处置,节约应急处置资源。
