The invention discloses a motor/non-motor vehicle illegal converse motion behavior detection method. The method comprises the following steps: acquiring real-time scene video stream data by adopting video stream acquisition equipment; aiming at a first frame video stream image of the collected scene video stream data, a dynamic 3D lane line segmentation detection algorithm is adopted to carry out lane line extraction and segmentation, a reference driving area is divided, and a correct reference driving direction in the reference driving area is calculated; tracking all maneuvering/non-motor vehicle targets by using a DeepSort real-time stream target tracking algorithm; pixel motion curve tracks of all maneuvering/non-motor vehicle targets in a period of time are fitted into a motion track straight line, a target motion direction is obtained, then an included angle between the target motion direction and a reference correct driving direction is calculated, and whether a target vehicle in a driving area has a retrograde motion behavior or not is judged through a self-adaptive threshold value. The method solves the problem of low detection precision of illegal converse driving behaviors of motor vehicles/non-motor vehicles at present.

    本发明公开了一种机动/非机动车非法逆行行为检测方法,采用视频流采集设备对实时的场景视频流数据进行采集;针对采集的场景视频流数据的首帧视频流图像,采用动态3D车道线分割检测算法进行车道线提取与分割,划分参考行车区域,并计算出参考行车区域内的正确参考行车方向;利用DeepSort实时流目标跟踪算法对所有机动/非机动车目标进行跟踪;将一段时间内所有机动/非机动车目标的像素运动曲线轨迹拟合为运动轨迹直线,获得目标运动方向,再计算目标运动方向与参考正确行车方向的夹角,通过自适应阈值判断行车区域内的目标车辆是否有逆行行为。上述方法解决了当前机动车/非机动车非法逆行行为检测精度较低的问题。
