The invention discloses a traffic flow statistics and congestion analysis method and system based on video analysis, and relates to the technical field of machine vision, and the method comprises the steps: obtaining a real-time video stream of a roadside camera; the video stream is monitored and maintained, and abnormity is reported when a picture is changed; performing data processing on the video stream to obtain processed data; performing target detection and tracking on the processed data to obtain detection and tracking results; performing image weather classification on the processed data to obtain a weather classification result; working condition division and parameter adjustment are carried out in combination with detection and tracking results and weather classification results; respectively judging whether the detection and tracking results pass through a starting line and an ending line, and respectively obtaining statistical results; respectively carrying out travel speed calculation, vehicle type classification and vehicle lane affiliation on the statistical result of passing through the end line, and recording information; and carrying out congestion degree analysis and flow statistics on each vehicle model according to the recorded information, and carrying out data reporting.

    本发明公开了一种基于视频分析的交通流量统计和拥堵分析方法和系统,涉及机器视觉技术领域,其中方法包括:获取路侧摄像头的实时视频流;对视频流进行监控和维护,对画面发生变化则上报异常;对视频流进行数据处理,获得处理后的数据;对处理后的数据进行目标检测和跟踪,获得检测和跟踪结果;对处理后的数据进行图像天气分类,获得天气分类结果;结合检测和跟踪结果及天气分类结果对工况划分和参数调整;对检测和跟踪结果分别进行是否经过起始线和是否经过结束线的判断,分别获取统计结果;对经过结束线的统计结果分别进行行程车速的计算、车辆类型分类和车辆车道归属,并记录信息;对记录的信息分析拥堵程度和各车型流量统计,进行数据上报。
