The invention relates to the technical field of intelligent traffic, and discloses a vehicle long-distance track restoration method, system and device. The method comprises the following steps: constructing a model training set based on vehicle tracking data, and training a path decision model based on the model training set; obtaining a license plate recognition result of the target vehicle in a preset time period, and determining all intersection positions through which the target vehicle passes based on the license plate recognition result to obtain a target intersection sequence; and based on the target intersection sequence and the trained path decision model, restoring to obtain a complete track of the target vehicle in a preset time period. Through the scheme of the invention, the problems of track fragmentation and incompleteness caused by only depending on a vehicle tracking algorithm are avoided, and the restoration effect of the long-distance continuous track of the vehicle is effectively improved, so that the active supervision requirement of the target vehicle in an intelligent network connection scene is met.

    本发明涉及智能交通技术领域,公开了一种车辆长距离轨迹还原方法、系统及设备。方法包括:基于车辆跟踪数据构建模型训练集,并基于模型训练集,训练路径决策模型;获取目标车辆在预设时间段内的车牌识别结果,基于车牌识别结果,确定目标车辆经过的所有交叉口位置以得到目标交叉口序列;基于目标交叉口序列和训练后的路径决策模型,还原得到目标车辆在预设时间段内的完整轨迹。通过本发明的方案,避免了仅依赖车辆追踪算法导致轨迹碎片化、不完整的问题,有效提升了车辆长距离连续轨迹的还原效果,从而满足智能网联场景下的目标车辆主动监管需求。
