Abstract: A method and a device for an assistance system, e.g. a parking assistance system, perform an autonomous or semi-autonomous driving maneuver of a vehicle. A camera system generates image data from the surroundings of the vehicle. A processor arrangement processes the image data to produce control information that is used by the assistance system to perform the driving maneuver. If the image data show that a restriction or impediment is present, then the assistance system is put in a safe state.
