Method and apparatus for determining a position information

The present invention relates to a method for determining a position information of a mobile vehicle, wherein the position information in response to a relative movement of the vehicle and a known starting position of the vehicle continuously by a position determining unit (2) is determined, with a) receiving at least one of a plurality (22 images) of a vehicle surrounding existing image sequence (21) (by a valve disposed in the vehicle camera system 4) b) determining of feature movements (23) (between temporally successive respective images detected 22) of the image sequence (21) (in the captured images 22) of the image sequence (21) image features by a first arithmetic unit one (6) Image processing unit (5), c) determining the relative self-movement information (24) of the camera system (4) as a function of feature movements of detected in the captured images of the image sequence image features between temporally successive images of the image sequence by a second computing unit (7) of the image processing unit (5), and d) calculating the relative movement of the vehicle in dependence on the determined feature movements (23) and the determined relative self-movement information (24) of the camera system (4) by the position detection unit (2).
