A METHOD ESTIMATING ABSOLUTE ORIENTATION OF A VEHICLE

摘要

The present invention relates to a method estimating absolute orientation of a vehicle by means of camera and GPS. The method requires few components and the principle components are a GPS (11) and a camera (5, 6). The method can be combined with existing navigation methods. According to the method of the invention the absolute orientation is obtained by the use of absolute position from the GPS (11) and relative motion from concurrent images (6) taken above an essentially horizontal ground.
