Abstract
A method and system of position determination using image deformation is provided. One implementation involves receiving an image of a visual tag, the image captured by an image capturing device, wherein the visual tag has a predefined position associated therewith; based on the image determining a distance of the image capturing device from the visual tag, and determining an angular position of the image capturing device relative to the visual tag; and determining position of the image capturing device based on said distance and said angular position.
