The invention relates to the technical field of image processing, in particular to an early warning method for abnormal driving of vehicles at an intersection, which comprises the following steps of: acquiring a position coordinate of each vehicle in each frame of intersection monitoring image so as to obtain an intermittent frame image of each vehicle; the method comprises the following steps: acquiring a direction angle and a speed of each vehicle at a first discontinuous frame image, estimating a position coordinate of each vehicle at the first discontinuous frame image to obtain a position coordinate of each vehicle in each frame of intersection monitoring image, and performing curve fitting on the position coordinate of each vehicle in each frame of intersection monitoring image to obtain a position coordinate of each vehicle in each frame of intersection monitoring image; obtaining a track path of each vehicle; clustering all the vehicles according to the similarity of the trajectory paths between the vehicles to obtain a plurality of clusters; according to the abnormal vehicle detection method and device, the accuracy of abnormal vehicle detection is improved.
本发明涉及图像处理技术领域,更具体地,本发明涉及一种用于路口车辆的异常行驶预警方法,该方法包括,采集每辆车在每帧路口监控图像中的位置坐标,进而得到每个车辆的间断帧图像,获取每个车辆在其第一间断帧图像处的方向角以及速度,进而对每个车辆在其第一个间断帧图像的位置坐标进行估计,得到每个车辆在每帧路口监控图像中的位置坐标,对每个车辆在每帧路口监控图像中的位置坐标进行曲线拟合,得到每个车辆的轨迹路径;根据车辆之间轨迹路径的相似性对所有车辆进行聚类,得到若干个聚类簇;获取每个聚类簇的异常程度,进而得到异常车辆,本发明提高了异常车辆检测的准确性。
