Abstract: An apparatus for determining a position on the basis of a camera image from a camera includes a Hough transformer, a positional description establisher and a database comparator. The Hough transformer is 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. The positional description establisher is 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. The database comparator further is 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.
