The invention provides a road intersection traffic volume analysis method and system, and the scheme comprises the steps: collecting a wide-angle video of a road intersection in real time, and obtaining the relative distance of different vertexes of the road intersection; acquiring a target vehicle image based on the wide-angle video, and determining a target vehicle model by using a pre-trained vehicle model classification model; based on the relative distance of different vertexes of the intersection, constructing a road intersection mapping model under a video coordinate system, and simulating a driving track of a target vehicle entering the intersection by using the mapping model; and counting the number of vehicles entering different directions of the intersection according to a simulation result, and obtaining the vehicle-type-based traffic volume of straight movement, left turn and right turn of each section in four directions of the intersection.

    本公开提供了一种道路交叉口交通量分析方法及系统,所述方案包括:实时采集道路交叉口的广角视频,并获取道路交叉口不同顶点的相对距离;基于所述广角视频获取目标车辆图像,利用预先训练的车型分类模型确定目标车辆车型;基于交叉口不同顶点的相对距离,构建视频坐标系下的道路交叉口映射模型,并利用所述映射模型对进入交叉口的目标车辆行驶轨迹进行模拟;根据模拟结果对进入交叉口不同方向的车辆数目进行统计,获得交叉口四个方向各断面直行、左转和右转的分车型交通量。
