The invention discloses a retrograde vehicle identification method and device, which are used for improving the retrograde vehicle identification accuracy. According to the scheme, the method comprises the steps that a road monitoring video of a target road is acquired, the road monitoring video comprises a plurality of road monitoring image frames arranged based on a time sequence, and any road monitoring image frame comprises an area where a to-be-detected vehicle is located; according to at least one road monitoring image frame, determining a collision line segment and a retrograde direction of the target road; identifying a moving track and a moving direction of the to-be-detected vehicle on the target road according to the plurality of road monitoring image frames arranged based on the time sequence; and if the included angle between the moving direction and the retrograde running direction is less than 90 degrees and the moving track intersects with the line collision segment, determining that the to-be-detected vehicle runs in the retrograde running direction.
本申请公开了一种逆行车辆识别方法和装置,用以提高逆行车辆识别准确性。本申请提供的方案包括:获取目标道路的道路监控视频,所述道路监控视频包括基于时序排列的多个道路监控图像帧,任一道路监控图像帧中包括待检测车辆的所在区域;根据至少一个道路监控图像帧确定所述目标道路的撞线线段和逆行方向;根据所述基于时序排列的多个道路监控图像帧识别所述待检测车辆在所述目标道路的移动轨迹和移动方向;如果移动方向与所述逆行方向的夹角小于90°且所述移动轨迹与所述撞线线段相交,则确定所述待检测车辆逆行。
