Claim Text:
1. A method for matching a region on an object of interest with a geolocation in a coordinate system, said method comprising: capturing an image of a region of an object of interest using an image capture device at a first location; processing said image to detect a located feature using a feature detection algorithm, wherein said feature detection algorithm is configured to detect said located feature at a two-dimension pixel coordinate in said image for further processing; further processing said located feature to derive a first feature descriptor using a feature descriptor extraction algorithm, wherein said feature descriptor extraction algorithm is configured to resample an area in said image around said located feature and derive a compact representation that is usable to identify said located feature and to distinguish said located feature from other features in said image; storing said first feature descriptor in a memory; searching a database of feature descriptors having geolocation information associated with the feature descriptors, for a match to said first feature descriptor; determining by said image capture device a geographic position of said image capture device based upon the geolocation information associated with said first feature descriptor; and making said geolocation information available for access.
