| Abstract: | Map matching is an effective way of improving location accuracy of vehicle location and navigation systems. By analyzing the application of map matching method in GPS/DR integrated navigation systems, a GPS/DR/Map matching integrated system model and a cost function based probabilistic map matching algorithm are proposed. Emphasis was put on how to eliminate the ambiguity in finding map matching resolution by evaluating a cost function for each correction over time. Simulation results show that, by introducing this algorithm, the positioning performance of integrated navigation system can be improved significantly. |
