Image-based georeferencing
First Claim
1. A computer-implemented method of providing georeferenced information regarding a location of capture of an image, said method comprising:
- receiving a first image at an image-based georeferencing system, said first image captured by a camera and comprising a terrestrial image of a physical object and comprising digital image information and an identifiable feature;
identifying a cataloged second image that correlates to said first image by determining, by said image-based georeferencing system, a common reference feature that is common to both said first image and said cataloged second image from an image database, wherein said common reference feature comprises said identifiable feature;
automatically determining a georeferenced position fix for said common reference feature, and wherein said common reference feature is not georeferenced in said second image identified from said image database;
utilizing said georeferenced position fix to determine a georeferenced location of capture of said first image;
locating, by said feature locator, additional features in a field of view of said first image based on said georeferenced position fix for said common reference feature; and
providing said georeferenced location of capture for access by a user of said image-based georeferencing system.

Abstract
A computer-implemented method of providing georeferenced information regarding a location of capture of an image is provided. The method includes receiving a first image at an image-based georeferencing system, the first image comprising digital image information and identifying a cataloged second image that correlates to the first image. The method further includes automatically determining reference features common to both the second image and the first image, accessing geographic location information related to the common reference features, utilizing the geographic location information related to the common features to determine a georeferenced location of capture of the first image and providing the georeferenced location of capture for access by a user of the image-based georeferencing system.

12. A computer-implemented method of updating a database of georeferenced images, said method comprising:
-
with an image-based georeferencing system, identifying a cataloged second image that correlates to a first image, said first image captured by a camera and comprising a terrestrial image of a physical object and; automatically determining a reference feature common to both said second image and said first image automatically determining a georeferenced position fix for said common reference feature, and wherein said common reference feature is not georeferenced in said second image; accessing geographic location information related to said common reference feature; associating said geographic location information with said reference feature in said first image to a create third image comprising a georeferenced version of said first image; locating additional features in a field of view of said first image based on said georeferenced position fix for said common reference feature; and storing said third image in a georeferenced image database. - View Dependent Claims (13, 14)
