Abstract

The invention pertains to a computer-implemented method (100) for characterizing a macrotexture of a ground surface, the method comprising receiving (110) 3D point cloud data of a scene, the scene comprising one or more ground surfaces, the 3D point cloud data comprising a plurality of ground points related to the one or more ground surfaces, selecting (130) a sampling unit of one of the ground surfaces, performing plane fitting (140) for fitting one or more planes, each plane representing a portion of the sampling unit, wherein the plane fitting is based on ground points related to the portion represented by the respective plane, calculating (150) a set of roughness indices, each roughness index characterizing the macrotexture of the sampling unit, wherein the calculation of each roughness index is based on distance values of ground points related to the respective portions, the distance values indicating a distance of the respective ground point relative to the respective plane, generating (160) output based on the set of roughness indices, and providing (170) a graphical representation of the output in a graphical user interface.
