Abstract
A trajectory correction method may include the steps of: correcting, by a map generation device, an error generated due to a change in position targeting 3D point cloud data collected in real time through a LiDAR, of which a position changes in real time; estimating, by the map generation device, an expected trajectory (odometry) related to the change in position on the basis of the corrected 3D point cloud data; applying, by the map generation device, curve fitting to the estimated expected trajectory; and mapping, by the map generation device, the expected trajectory before the curve fitting targeting the expected trajectory to which the curve fitting is applied.
