MAP MATCHING METHOD IN CROSSROAD AND NAVIGATION SYSTEM

摘要

It is provided to more natural and reality guide in crosspoint in a kind of map-matching method of crosspoint and a navigation system, by in the rotation guide in crosspoint one scheduled curvature of reflection to surveying and mapping data. A kind of map-matching method in crosspoint includes the step for searching for a paths, to the step for reflecting a curvature corresponding with the type in the crosspoint of the map-matching data for the rotation guide in crosspoint and turn direction by user designated destination and when crosspoint is detected. One navigation system includes a path-calculating element (220), storage (230), a user interface (240), a display unit (250), a voice output unit (260), and a controller (270), it there include that storage is stored according to a cross-point data library of the determining curvature of the type and turn direction in crosspoint.
