The invention discloses a global vehicle trajectory tracking method and system, and relates to the technical field of data processing, and the method comprises the steps: carrying out the driving data detection of a target vehicle based on a radar group, obtaining first vehicle data, and determining a handover time node of each millimeter radar as a verification time point; driving data, uploaded by the vehicle-mounted terminal, at the verification time point are called to serve as second vehicle data; performing mapping verification on the first vehicle data and the second vehicle data to obtain a target verification result and compensated driving data; identifying a target verification result, and judging whether a tracking error of the millimeter radar exists or not; and if yes, performing real-time tracking adjustment of the millimeter radar based on the compensated driving data. The technical problem of low vehicle tracking accuracy caused by single global vehicle trajectory tracking method in the prior art is solved, and the technical effect of improving the vehicle tracking accuracy by checking and adjusting the tracking data of the radar through the vehicle-mounted terminal data is achieved.

    本发明公开了一种全域车辆轨迹追踪方法及系统,涉及数据处理技术领域,该方法包括:基于雷达组群,对目标车辆进行行车数据检测,获取第一车辆数据,确定各毫米雷达的交接时间节点,作为验证时刻点;调用车载终端上传的验证时刻点的行车数据,作为第二车辆数据;将第一车辆数据与第二车辆数据映射校验,获取目标验证结果和补偿行车数据;识别目标验证结果,判断是否存在毫米雷达的追踪误差;若是,基于补偿行车数据进行毫米雷达的实时追踪调整。本发明解决了现有技术中由于全域车辆轨迹追踪方法单一,导致车辆追踪准确度低的技术问题,达到了通过车载终端数据对雷达的追踪数据进行校验调整,提高车辆追踪的准确度的技术效果。
