| Abstract: | General principles of map matching are investigated according to segmentation and feature extraction, and an algorithm based on D S evidence reasoning for GPS/MM integrated navigation system is proposed. The single point positioning accuracy of GPS is improved. Finally, a simulation example demonstrates the effectiveness of the proposed algorithm for the requirement of vehicle position and navigation. The map matching algorithm does not increase the cost of system hardware. It is a useful solution for the widely used GPS navigation and position system. |
