The invention relates to a vehicle illegal behavior detection method based on video monitoring, and the method comprises the steps: determining the side boundary of each lane monitoring region in a video, carrying out the frame selection of vehicles entering the lane monitoring regions, and determining the centroid coordinates of the vehicles; drawing a horizontal ray by taking the center-of-mass coordinate as a base point; judging whether the vehicle has a lane changing behavior or not according to the intersection number of the horizontal ray and the sideline of the lane area of the vehicle; and if the vehicle has the lane changing behavior and the vehicle still has the lane changing behavior within a period of time when the lane changing behavior occurs, judging that the vehicle has the continuous lane changing behavior. According to the detection method, the vehicle monitoring area is established in the lane, the centroid coordinate of the vehicle entering the area is positioned, the horizontal ray is established by taking the centroid coordinate as a base point, and whether the vehicle continuously changes the lane or not is judged according to the intersection number of the horizontal ray and the sideline of the vehicle monitoring area. According to the method, the vehicle can be detected in real time, and the accuracy is high.
本发明涉及一种基于视频监控的车辆违法行为检测方法,该方法包括:确定视频内各车道监测区域边线,同时对进入车道监测区域内的车辆进行框选,确定车辆的质心坐标;以质心坐标为基点绘制水平射线;根据水平射线与车辆所在车道区域边线的交点数,判断车辆是否存在变道行为;若车辆存在变道行为,且该变道行为发生的一段时间内该车辆还存在变道行为,则判断车辆存在连续变道行为。上述检测方法,通过在车道内建立车辆监测区域,并对进入该区域的车辆的质心坐标进行定位,同时以该质心坐标为基点建立水平射线,通过该水平射线与车辆监测区域边线的交点数判断车辆是否存在连续变道,该方法能够对车辆进行实时检测,且准确性较强。
