The invention provides a method and a device for determining missing time of track point detection on an expressway, and the method comprises the steps: determining a time length distribution function corresponding to each track missing road segment based on the historical passing time length of a target vehicle on each track missing road segment on the expressway; based on each duration distribution function and a target duration constraint condition corresponding to each trajectory missing road section, determining target functions corresponding to all trajectory missing road sections; carrying out optimization solution on the target function, and determining a target time length corresponding to each track missing road section of the target vehicle; and based on each target duration and the time information of the corresponding track detection point of the target vehicle on the track normal road section, determining missing time information of the corresponding track detection point of the target vehicle on each track missing road section. According to the method and the device, the missing time information of the target vehicle on the expressway at the trajectory detection point corresponding to the trajectory missing road section can be determined, and the accuracy of complementing the missing trajectory point is improved.

    本申请提供了一种高速公路上检测轨迹点的缺失时间的确定方法及装置,确定方法包括:基于目标车辆在高速公路上的各个轨迹缺失路段的历史通行时长,确定各个轨迹缺失路段对应的时长分布函数;基于各个时长分布函数以及各个轨迹缺失路段对应的目标时长约束条件,确定全部轨迹缺失路段对应的目标函数;针对目标函数进行优化求解,确定目标车辆在各个轨迹缺失路段对应的目标时长;基于各个目标时长和目标车辆在轨迹正常路段上对应的轨迹检测点的时间信息,确定目标车辆在各个轨迹缺失路段上对应的轨迹检测点的缺失时间信息。本申请能够确定高速公路上目标车辆在轨迹缺失路段对应的轨迹检测点的缺失时间信息,提升了对缺失的轨迹点补全的准确性。
