Abstract

A computer-implemented method for generating non-semantic reference data for determining the position of a motor vehicle involves a set of raw data points being provided that models a stipulated surrounding area. A stipulated descriptor characterizing a property of the surrounding area is determined for each of the raw data points. At least one point cluster is generated by grouping the raw data points on the basis of their descriptors. A characteristic number relating to an information gain for determining the position of the motor vehicle is assigned to a first point cluster on the basis of the descriptors of the raw data points. The characteristic number is taken as a basis for storing feature information of the first point cluster on a memory unit as non-semantic reference data for determining the position.
