A method and apparatus for providing a 3-dimensional ground surface model used for mapping

摘要

A method for providing a 3-dimensional ground surface model of a ground surface surrounding a vehicle (1), the method comprising providing (S1) radar data on the surrounding ground surface by a built-in radar system (3A) of the vehicle (1); generating (S2) a radar surface height map on the basis of the provided radar data; and deriving (S3) the 3-dimensional ground surface model from the generated radar surface height map.
