The invention discloses a vehicle driving track reconstruction method and system under bayonet data loss. The method comprises the steps of obtaining bayonet data; generating a vehicle initial track according to the checkpoint data; carrying out track splitting on the initial track of the vehicle to generate a plurality of undetermined path segments; analyzing the to-be-determined path segment byadopting a particle swarm optimization algorithm, and determining a feasible path of the vehicle driving track; selecting an optimal path in the feasible paths of the vehicle driving track by using anetwork analytic hierarchy process to obtain a final vehicle driving track. Therefore, vehicle driving track reconstruction during bayonet data missing is realized. 本公开公开的一种卡口数据缺失下的车辆行车轨迹重建方法及系统，包括：获取卡口数据；根据卡口数据生成车辆初始轨迹；对车辆初始轨迹进行轨迹拆分，生成多个待定路径段；采用粒子群优化算法对待定路径段进行分析，确定车辆行车轨迹可行路径；利用网络层次分析法选取车辆行车轨迹可行路径中的最优路径，为最终的车辆行车轨迹。实现了卡口数据缺失时的车辆行车轨迹重建。
