Abstract
A vehicle position information acquisition device includes: a position information detector that detects position information of a vehicle; a map data storage that stores a feature type of a feature on a map and a position data group in association with each other; an imaging unit that images a region ahead of the vehicle; a feature detector that detects a surrounding feature; a reference position data group extractor that extracts a reference position data group; a reference position data group storage; a comparative position data group extractor that extracts a comparative position data group; a comparative position data group storage; an error processor that associates reference position data with comparative position data having a shortest distance and calculates an error in a distance between the reference position data and the comparative position data that are associated with each other; and a correction unit that corrects the position information.
