Abstract:
A method for matching a region on an object of interest with a geolocation in a coordinate system is disclosed. In one embodiment, an image of a region on an object of interest is captured on an image capture device. The image is processed to detect a located feature using a feature detection algorithm. Further processing of the located feature is performed to derive a first feature descriptor using a feature descriptor extraction algorithm. The feature descriptor is stored in a memory. A database of feature descriptors having geolocation information associated with the feature descriptors is searched for a match to the first feature descriptor. The geolocation information is then made available for access.
