Method of Map Matching for Personal Positioning System
Yin Jianghui · Jisuanji gongcheng · 2005
While it has already been in practical use for car navigation systems, its simple based on distance and direction estimation is not sufficient for tracking of man’s complicated movement. In addition, matching should be done for three-dimension maps because human movement consists of both vertical and horizontal motion. The algorithm proposed in this paper combines two of the current algorithms, one of which is based on matching one’s shift patterns with shapes of road network, and the other is for a frequent step-by-step adjustment of one’s estimated position against outlines of objects around it. Using this integrating algorithm ,the paper proposes a new map matching method which give goods performance in terms of accuracy of positioning system for human movement in 3D space.
