The embodiment of the invention discloses a vehicle backtracking method, which comprises the following steps of: if preset image acquisition equipment acquires image information of a target vehicle at a preset moment, acquiring image information of the target vehicle on a driving track of the target vehicle; acquiring a traffic state of a target road section between a target image acquisition device and the preset image acquisition device at the preset moment; determining a corresponding speed equivalent value of the target vehicle on the target road section by using the speed coefficient corresponding to the traffic state at the preset moment; according to the speed equivalent value and the preset moment, calculating the time when the target vehicle passes through the target image acquisition equipment to obtain a target moment; querying the target vehicle in image information corresponding to the target moment acquired by the target image acquisition equipment; and after the target vehicle is inquired, according to the position information of the target image acquisition equipment, carrying out backtracking on the driving track of the target vehicle.
本申请实施例公开了一种车辆的回溯跟踪方法,包括:如果预设图像采集设备在预设时刻采集到所述目标车辆的影像信息,则在所述目标车辆的行车轨迹上,获取目标图像采集设备与所述预设图像采集设备之间的目标路段在所述预设时刻的交通状态;利用所述预设时刻的交通状态对应的速度系数,确定所述目标车辆在所述目标路段对应的速度等效值;根据所述速度等效值和所述预设时刻,计算所述目标车辆经过所述目标图像采集设备的时间,得到目标时刻;在所述目标图像采集设备采集的所述目标时刻对应的影像信息中,查询所述目标车辆;在查询到所述目标车辆后,根据所述目标图像采集设备的位置信息,对所述目标车辆的行驶轨迹进行回溯跟踪。
