APPARATUS AND METHOD FOR CORRECTING INFORMATION OF POSITION

摘要

PURPOSE: An apparatus for correcting information of position and a method thereof are provided to improve positioning accuracy in order to be used in position-based service or space information service of high quality through the same. CONSTITUTION: A position correcting apparatus (100) includes a reference object search part (150), a reference point extracting part (160) and a position determining part (170). The reference object search part searches an object corresponding to a photographed image from a previously stored geographic object database, and sets a reference object which is to be used in position correction among the searched objects. The reference point extracting part sets a reference point in the established reference object. The position determining part acquires actual distance between the reference points, and calculates the position by using the actual distance and the distance between reference points included in the photographed image and metal information of the photographed image.
