Apparatus for determining a position on the basis of a camera image from a camera, comprising: a Hough transformer formed to identify circular arcs or elliptical arcs in the camera image or in a preprocessed version of the camera image derived therefrom, and to identify a plurality of straight stretches passing in various directions through the camera image or through the preprocessed version, wherein the Hough transformer is formed to provide information on a position of an identified circular arc or elliptical arc, and to provide information on a radius of curvature of the identified circular arc or elliptical arc; a positional description establisher formed to obtain a positional description describing the identified circular arcs or elliptical arcs and the identified straight stretches by parameters, on the basis of the identified circular arcs or elliptical arcs and on the identified straight stretches, wherein the positional description for identified circular arcs or elliptical arcs comprises information on a position of an identified circular arc or elliptical arc and information on a radius of curvature of the identified circular arc or elliptical arc; and a database comparator formed to compare the positional description with a plurality of comparative positional descriptions, and to obtain information on a position as a result of the comparison, wherein the database comparator is formed to form a difference between a feature vector of the positional description and feature vectors of the comparative positional descriptions, and, responsive to the difference for one of the comparative positional descriptions being sufficiently small, to output positional information belonging to the corresponding comparative positional descriptions as a result, wherein the positional description establisher is formed to obtain a description of a course of the road, which reproduces the course as an ordered description of identified circular arcs or elliptical arcs and straight stretches, as the positional description. a Hough transformer formed to identify circular arcs or elliptical arcs in the camera image or in a preprocessed version of the camera image derived therefrom, and to identify a plurality of straight stretches passing in various directions through the camera image or through the preprocessed version, wherein the Hough transformer is formed to provide information on a position of an identified circular arc or elliptical arc, and to provide information on a radius of curvature of the identified circular arc or elliptical arc; a positional description establisher formed to obtain a positional description describing the identified circular arcs or elliptical arcs and the identified straight stretches by parameters, on the basis of the identified circular arcs or elliptical arcs and on the identified straight stretches, wherein the positional description for identified circular arcs or elliptical arcs comprises information on a position of an identified circular arc or elliptical arc and information on a radius of curvature of the identified circular arc or elliptical arc; and a database comparator formed to compare the positional description with a plurality of comparative positional descriptions, and to obtain information on a position as a result of the comparison, wherein the database comparator is formed to form a difference between a feature vector of the positional description and feature vectors of the comparative positional descriptions, and, responsive to the difference for one of the comparative positional descriptions being sufficiently small, to output positional information belonging to the corresponding comparative positional descriptions as a result, wherein the positional description establisher is formed to obtain a description of a course of the road, which reproduces the course as an ordered description of identified circular arcs or elliptical arcs and straight stretches, as the positional description.
