The invention belongs to the technical field of intelligent traffic, and particularly relates to a data preprocessing method and system for accurately restoring an actual passing track of a vehicle, which are used for eliminating the influence of abnormal portal data on a vehicle highway path restoration result. The method provided by the invention comprises the following steps: S1, fusing and de-weighting; s2, reconstructing and sorting; s3, removing reverse marks and false marks; and S4, homogenizing the portal. According to the method provided by the invention, the portal transaction flow and the license plate recognition data are fused, the fused data are processed, the gantries subjected to reverse marking and error marking are eliminated, the abnormal gantries are eliminated, the portal data are subjected to portal homogenization processing, and the actual passing track of the vehicle is accurately restored to the maximum extent. The system provided by the invention can be independently developed, deployed and operated, and the operation stability of the existing system is not influenced.

    本发明属于智能交通技术领域,具体涉及用于消除异常的门架数据对车辆高速公路路径还原结果影响的一种精确还原车辆实际通行轨迹的数据预处理方法和系统。本发明提供的方法包括:S1:融合去重;S2:重构排序;S3:去反标误标;S4:门架同质化。本发明提供的方法对门架交易流水和车牌识别数据进行融合,并对融合后的数据进行处理,剔除反标误标的门架、消除异常的门架,并对门架数据进行门架同质化处理,最大限度的精确还原车辆实际通行轨迹。本发明提供的系统可独立开发、部署、运行,不影响现有系统运行的稳定性。
