  • Patent number: 9297653
    Abstract: Disclosed herein is a location correction apparatus and method. The location correction apparatus includes 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 sets reference points from the set reference object. A location determination unit obtains an actual distance between the reference points and calculates a location using the actual distance, a distance between the reference points included in the captured image, and metadata of the captured image. Therefore, the present invention can improve positioning accuracy and can be applied to high-quality location-based services or space information services thanks to the improved accuracy.
