The invention discloses a method and device for detecting random lane change of a vehicle, and the method comprises the following steps: carrying out the preprocessing of lane information according to a monitoring image, and marking a lane line on the monitoring image; detecting an object in the monitoring image, and judging whether the object is a vehicle or not; positioning the vehicle identified in the vehicle detection module and selecting a target vehicle through a rectangular frame line; judging a vehicle rectangular wireframe, if the aspect ratio of an external rectangle is larger than a threshold value, carrying out secondary frame selection, fitting a more accurate vehicle frame line through a database, and otherwise, indicating that the rectangular wireframe is the vehicle frame line; and judging whether the vehicle has illegal behaviors or not according to the relation between the marked lane line and the vehicle frame line of the moving vehicle. According to the invention, the illegal lane changing phenomenon of the vehicle is detected in real time, so that various illegal lane changing behaviors of the road are monitored, the judgment precision is improved, and the occurrence rate of illegal lane changing events is greatly reduced.
本发明公开了一种车辆随意变道检测的方法及装置,包括以下步骤:根据监控图像对车道信息进行预处理,并将车道线标记在监控图像上;对监控图像中物体进行检测,判断是否为车辆;对车辆检测模块中识别的车辆进行定位,并通过矩形框线将目标车辆框选出来;对车辆矩形线框进行判断,如果外接矩形的宽高比大于阈值,则进行二次框选,通过数据库拟合出更精确的车辆框线,否则,矩形线框即为车辆框线;根据对比标记的车道线和运动车辆的车辆框线的关系来判断车辆是否存在违法行为。本发明通过实时检测车辆违法变道现象的发生,实现了对道路各种违法变道行为的监控,提高了判断精度,极大的降低了此类违法变道事件的发生率。
