The invention discloses a trajectory correction method and device, and unmanned equipment can obtain a driving trajectory of the unmanned equipment and point cloud data collected at the current moment, and then the unmanned equipment can predict a position corresponding to the current moment of the unmanned equipment according to the driving trajectory as a to-be-corrected position, and according to the collected point cloud data, a data correction parameter corresponding to the current moment of the unmanned equipment is determined, and the unmanned equipment can correct the to-be-corrected position according to the data correction parameter to obtain a corrected position. And finally, the unmanned equipment can correct the driving track according to the corrected position to obtain the actual driving track of the unmanned equipment, so that the positioning accuracy of the unmanned equipment is effectively ensured.

    本说明书公开了一种轨迹修正的方法及装置,无人驾驶设备可以获取自身的行驶轨迹以及当前时刻采集到的点云数据,而后,无人驾驶设备可以根据该行驶轨迹,预测无人驾驶设备当前时刻对应的位置,作为待修正位置,以及根据采集到的点云数据,确定该无人驾驶设备当前时刻对应的数据校正参数,无人驾驶设备可以根据该数据校正参数,对该待修正位置进行修正,得到修正后位置。最后,无人驾驶设备可以根据该修正后位置,对行驶轨迹进行修正,以得到该无人驾驶设备的实际行驶轨迹,从而有效地保证了无人驾驶设备定位的准确性。
