1. A vehicle vision system, comprising:

  • a camera installed in a car and configured to capture at least one image; and

    a processor coupled to the camera and configured to determine at least one feature descriptor for the at least one image; and

    a wireless communication device;

    the processor having an interface coupled to the wireless communication device to access annotated map data including geo-referenced feature descriptors to retrieve over the wireless communication device a plurality of geo-referenced feature descriptors and position information respectively associated with the geo-referenced feature descriptors,where the processor is configured to perform a matching procedure between the at least one feature descriptor determined for the at least one image and the retrieved geo-referenced feature descriptors, where the processor is configured to transmit the at least one image to a server over the wireless communication device selectively if no match is found for the at least one feature descriptor determined for the at least one image in the matching procedure,where the processor is configured to control an optical output device such that both a position and an orientation at which graphics are output by the optical output device are controlled based on an angle which defines a rotational position of the car around its longitudinal axis determined by the matching procedure.
