The invention discloses an urban traffic road traffic flow data acquisition and analysis processing system based on video monitoring. The monitoring video of each sub-region in a to-be-processed urban traffic road region is obtained, and each vehicle image in the monitoring video of each sub-region in each time period is extracted; the type of vehicles corresponding to each vehicle image in the monitoring video of each section of sub-region in each time period are compared and screened, the number of each type of vehicles in the monitoring video of each section of sub-region in each time period is counted, and the appearance time and disappearance time of each vehicle in the monitoring video of each section of sub-region in each time period are extracted; the driving speed of each vehicle in the monitoring video of each section of sub-region in each time period is calculated, the number of times of traffic accidents in the monitoring video of each section of sub-region in each time period is counted, the traffic flow influence coefficient of each section of sub-region is comprehensively calculated, and if the traffic flow influence coefficient of a certain section of sub-region is greater than a set threshold value, related personnel is notified of vehicle guidance.
本发明公开基于视频监控的城市交通道路车流数据采集和分析处理系统,通过获取待处理的城市交通道路区域内各段子区域的监控视频,并提取各段子区域在各时间段的监控视频中各车辆图像,对比筛选各段子区域在各时间段的监控视频中各车辆图像对应的类型车辆,统计各段子区域在各时间段的监控视频中各类型车辆数目,同时提取各段子区域在各时间段的监控视频中各车辆的出现时间和消失时间,计算各段子区域在各时间段的监控视频中各车辆的行驶速度,并统计各段子区域在各时间段的监控视频中发生车祸的次数,综合计算各段子区域的车流量影响系数,若某段子区域的车流量影响系数大于设定的阈值,则通知相关人员进行车辆疏导。
