Claim Text:
1. A location correction apparatus comprising one or more computers configured to implement: a reference object search unit for searching a pre-stored geographic object database (DB) for one or more objects corresponding to objects included in a captured image and setting a reference object to be used to correct a location among the one or more objects that have been found; a reference point extraction unit for setting reference points from the set reference object; and a location determination unit for obtaining an actual distance between the reference points and calculating a location using the actual distance, a distance between the reference points included in the captured image, and metadata of the captured image; wherein the location determination unit calculates the actual distance between the reference points using actual coordinates of the reference points included in the captured image, calculates an angle between the reference points and a capturing location or origin, and calculates the location using the actual distance, the distance between the reference points in the captured image, an angle of view of the captured image, a size of the captured image, and the angle between the reference points and the capturing location or origin.
