The invention discloses a method for eliminating abnormal vehicle detection tracking position caused by pixel frame jitter. The method comprises the following steps: acquiring a queuing area of a target intersection; acquiring real-time vehicle passing data detected by an intersection camera, and converting a vehicle pixel coordinate into a UTM coordinate; based on the UTM coordinates, using Kalman filtering to track the vehicle so as to obtain the real-time position, speed and course angle of the vehicle; queuing area matching is carried out, intersection queuing area matching is carried out on the real-time vehicle position, and vehicles located in a queuing area are obtained; judging whether the current state is a motion state or a static state according to the historical and current speeds of the vehicle and the historical motion state of the vehicle; and judging whether the current position change of the vehicle is reasonable or not by combining the UTM coordinate system characteristics, the current motion state of the vehicle and whether the vehicle is located in the queuing area, and performing position calibration if the current position change is not reasonable. According to the method, the phenomenon of abnormal vehicle detection tracking position caused by pixel frame jitter in the intersection scene is eliminated, and the problem of abnormal vehicle detection tracking position caused by the camera in the traffic scene application field is solved.
一种消除像素框抖动导致车辆检测跟踪位置异常的方法,包括以下步骤:采集目标路口的排队区域;获取路口相机检测的实时过车数据,将车辆像素坐标进行转换,转为UTM坐标;基于UTM坐标,使用卡尔曼滤波对车辆进行跟踪,以获取车辆实时的位置、速度、航向角;进行排队区域匹配,将实时车辆位置进行路口排队区域匹配,获取位于排队区域的车辆;通过车辆历史和当前的速度、车辆历史运动状态,判断当前的状态是运动还是静止;结合UTM坐标系特征、车辆当前的运动状态、车辆是否位于排队区域,判断车辆当前位置变化是否合理,不合理时进行位置校准。本发明消除路口场景下像素框抖动导致车辆检测跟踪位置异常的现象,解决相机在交通场景应用领域带来的车辆检测跟踪位置异常问题。
