The invention relates to a vehicle abnormal position correction method, system and device based on road network position information and a medium, and the method comprises the steps: collecting and processing road network map information, tracking a vehicle position, and storing the vehicle position as a historical position point set; when the number of the historical position points exceeds a set threshold value, whether the vehicle is in an abnormal deviation state or not is judged according to the scene where the vehicle is located and the relative position relation between the vehicle and the road and road section range; if the vehicle is in the abnormal deviation state, acquiring a latest position point from a historical position point set, and predicting and covering the position of the vehicle; if not, front and back position abnormal state identification is carried out; and when the front and back positions are identified to be abnormal, obtaining the latest position point from the historical position point set, and predicting and covering the position of the vehicle. According to the invention, by fully utilizing and fusing a plurality of data sources, designing an innovative judgment rule and adopting a refined exception handling mode, the accuracy of vehicle position judgment and the fineness of exception handling are remarkably improved.
本发明涉及一种基于路网位置信息的车辆异常位置纠偏方法、系统、设备以及介质,其方法包括:采集并处理路网地图信息,跟踪车辆位置,并存储为历史位置点集合;在历史位置点数量超过设定阈值时,根据车辆所处场景及与道路、路段范围的相对位置关系,判断车辆是否处于异常偏出状态;若处于异常偏出状态,从历史位置点集合中获取最新位置点,预测并覆盖车辆位置;若未处于异常偏出状态,进行前后位置异常状态识别;在被识别为前后位置异常,从历史位置点集合中获取最新位置点,预测并覆盖车辆位置。本发明提出通过充分利用和融合多种数据源、设计创新的判定规则以及采用精细化的异常处理方式,显著提升了车辆位置判断的准确性和异常处理的精细度。
