SNAKE: A NEW INFORMATION FUSION APPROACH TO AUGMENT GPS USING MAP-DERIVED INFORMATION

A physically based information fusion approach which greatly differs from the commonly used probabilistic approach is introduced. In this approach, a road is represented as a deformable model composed of an abstract elastic material. The combination of GPS (global positioning system) measurements with map derived information is accomplished by using a physically based least action principle. The optimal information fusion can be achieved by solving energy minimizing equations of the motion. Tests on simulated data show that this approach opened a new avenue for integrating map derived information to augment GPS for vehicle navigation. The feasibility, effectiveness, and distinctive features of this new approach are demonstrated in this paper.
