    Abstract: A map matching apparatus of the navigation for pedestrians using dead reckoning and a method thereof are provided to minimize accumulative influence of error caused by the dead reckoning by matching map by correcting the matched location to a new initial position. A map matching apparatus(100) of the navigation for pedestrians using dead reckoning comprises a dead reckoning part(110), a current position estimating part(120), a link selection part(130), a matching part(140). The dead reckoning part estimates traveling direction and relative translation distance from initial position.

The link selection part selects the matched link from a map including the current position. The matching part indicates the current position on the link by matching the current position. The map matching device matches the map by setting up the location matched on the link at the new initial position.
