Abstract
A road surface recognition method may include extracting first point cloud data in a front road surface region of a vehicle from point cloud data generated by LiDAR of the vehicle, generating a point cloud map by use of a local map and the first point cloud data, determining a predicted driving route of the vehicle based on motion-related data of the vehicle; and generating a road surface height profile of the predicted driving route based on the point cloud map and the predicted driving route.
