LOCATION OF IMAGE CAPTURE DEVICE AND OBJECT FEATURES IN A CAPTURED IMAGE
First Claim
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;
further processing said located feature to derive a first feature descriptor using a feature descriptor extraction algorithm;
storing said 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; and
making said geolocation information available for access.

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.

37. A system for determining the location of an image capture device, said system comprising:
-
an image capture device comprising; a processor coupled with a bus; a memory coupled with a bus; and a camera; and an image database comprising; a memory coupled with a bus; and a processor coupled with said bus, said processor configured to access a feature descriptor of an image received from said image capture device and match said feature descriptor with a corresponding feature descriptor having geolocation information associated therewith, said processor further configured to make said geolocation information available for access as a result of matching said feature descriptor with said corresponding feature descriptor. - View Dependent Claims (38, 39, 40, 41)
