The invention discloses a vehicle track missing complementing tracking method and system. The method comprises the following steps: acquiring a target vehicle passing track and passing area road information; retrieving all possible passing paths of the target vehicle according to the missing road section and the passing area road information, and retrieving all reference vehicle tracks matched with the possible passing paths in the historical passing data of the missing road section; and calculating a possible passage path which most conforms to the missing road section track by utilizing a backtracking passage probability method and combining with the reference vehicle track, and complementing the target vehicle passage track by utilizing the possible passage path. According to the method, the road rule information and the road traffic condition of the GIS map are combined, and the probability model is combined with the existing historical vehicle traffic data to calculate the path with the maximum probability of traffic, so that path completion is performed, high calculation precision can be ensured under the condition of lack of monitoring, the complete track of the suspected vehicle is obtained, and the real-time performance of the suspected vehicle is improved. Therefore, travel analysis of the suspected vehicle can be carried out.
本发明公开了一种车辆轨迹缺漏补全跟踪方法及系统,包括:获取目标车辆通行轨迹和通行区域道路信息;根据缺漏路段及通行区域道路信息,检索目标车辆所有可能通行路径,检索缺漏路段历史通行数据中所有与可能通行路径匹配的参照车辆轨迹;利用回溯通行概率法,结合参照车辆轨迹计算出最符合缺漏路段轨迹的可能通行路径,并利用可能通行路径补全目标车辆通行轨迹。本发明通过结合GIS地图的道路规则信息及道路通行情况,利用概率模型结合已有的历史车辆通行数据计算出最大概率通行的路径,从而进行路径补全,能在缺乏监控的情况下也能保证较高的计算精度,得到嫌疑车辆的完整轨迹,以便进行嫌疑车辆的出行分析。
