The invention discloses a road condition detection method and device, equipment and a medium. The method comprises the following steps: performing vehicle detection on multiple frames of video images acquired by a target camera to obtain a detection frame of each vehicle in the video images; and according to the center point of the detection frame of each vehicle in the video image, determining the driving track of the vehicle. And then grouping the driving tracks based on the included angles between the track lines of the driving tracks and the longitudinal axis of the image coordinate system, and then dividing the driving tracks in the same driving direction into the same track group. And then, determining the average speed of the track group according to the detection frame of the vehicle corresponding to each driving track in the track group, and determining a road condition detection result of whether the road section corresponding to the track group is congested or not based on the average speed. The process does not need to set a road condition detection reference standard according to a shooting scene, is simple and convenient to operate, and is suitable for various camera shooting scenes.
本申请公开了一种路况检测方法、装置、设备及介质。该方法包括:通过对目标相机采集的多帧视频图像进行车辆检测,得到视频图像中每一车辆的检测框。继而根据每一车辆在视频图像中的检测框中心点,确定该车辆的行车轨迹。然后基于行车轨迹的轨迹线与图像坐标系纵轴的夹角,对各行车轨迹进行分组,继而将相同行驶方向的行车轨迹分到相同轨迹组。接下来,根据轨迹组内各行车轨迹对应车辆的检测框确定轨迹组的平均车速,并基于该平均车速确定轨迹组对应路段是否拥堵的路况检测结果。上述流程无需根据拍摄场景来设置路况检测的参考标准,操作简便且适用于多种相机拍摄场景。
