Patent ID: 8547375

Claim:
A method for identifying within a working image of a scene a point of interest designated within a designation image of the scene, the designation image being taken along a first viewing direction and the working image being taken along a second viewing direction, the second viewing direction being significantly non-parallel to the first viewing direction, the method comprising the steps of: (a) obtaining a designation image of the scene; (b) obtaining a working image of the scene; (c) correlating said designation image and said working image with each other, directly or by correlating each of said designation image and said working image with a common reference image, so as to derive an interrelation between said designation image and said working image; and (d) employing said interrelation between said designation image and said working image to derive a location within said working image of a point of interest designated within said designation image, characterized in that the method further comprises: (e) obtaining a secondary designation image taken along a viewing direction displaced from, but similar to, the first viewing direction, said designation image and said secondary designation image being a pair of similar images with similar resolution and similar angular field of view; and (f) co-processing said designation image and said secondary designation image to derive range information relating to a plurality of pixels in said designation image, thereby defining a partial relative three-dimensional model of a portion of the scene relative to the viewing direction of said designation image, wherein said step of correlating includes employing said partial relative three-dimensional model to generate a simulated image generated by warping said designation image to approximate a view taken along said second viewing direction and correlating said working image with said simulated image, and wherein said steps of correlating, employing and co-processing are implemented using at least one processing system comprising at least one processor.
