Abstract

A wireless position detection apparatus specifies, on a road, a target point corresponding to a current position correspondence point of a moving object and calculates a positioning coordinate of the target point as current position information of the moving object based on (i) position information of the current position correspondence point of the moving object on the coverage map, (ii) the position information of the auxiliary points positioned immediately prior to and immediately posterior to the current position correspondence point on the coverage, and (iii) the position data of the map objects corresponding to the auxiliary points positioned immediately prior to and immediately posterior to the current position correspondence point on the coverage map.
