Image-based georeferencing
First Claim
1. A method of obtaining geolocation information, said method comprising:
- capturing a first image with a camera to achieve a captured image, said captured image comprising a field of view including an object with an identifiable feature;
providing said captured image to an image-based georeferencing system, said image-based georeferencing system comprising a feature locator configured for accessing geographic location information;
determining, by said image-based georeferencing system, a common reference feature that is common to both captured image and an image identified from an image database, wherein said common reference feature comprises said identifiable feature;
retrieving, by said feature locator of said image-based georeferencing system, a georeferenced position fix for said common reference feature, and wherein if said common reference feature is not georeferenced in said image identified from said image database, accessing, by said image-based georeferencing system, a geospatial and geographic information system (GIS) to identify said common reference feature and to obtain said geographic location information related to said common reference feature;
receiving, from said feature locator, an accuracy level determination for said georeferenced position fix, wherein said accuracy level determination comprises a description of a level of accuracy for a source rendering said georeferenced position fix, wherein said accuracy level determination further comprises an accuracy validation comprising a validation of a presence of Z-coordinate information in said georeferenced position fix;
locating, by said feature locator, additional features in said field of view of said captured image based on said georeferenced position fix for said common reference feature and said accuracy level determination; and
receiving, from said image-based georeferencing system, an augmented version of said first image comprising augmented location information regarding said field of view.

Abstract
An image-based georeferencing system comprises an image receiver, an image identification processor, a reference feature determiner, and a feature locator. The image receiver is configured for receiving a first image for use in georeferencing. The image comprises digital image information. The system includes a communicative coupling to a georeferenced images database of images. The image identification processor is configured for identifying a second image from the georeferenced images database that correlates to the first image. The system includes a communicative coupling to a geographic location information system. The reference feature determiner is configured for determining a reference feature common to both the second image and the first image. The feature locator is configured for accessing the geographic information system to identify and obtain geographic location information related to the common reference feature.
