Abstract
A system and method is provided for determining the location of a device based on image of objects captured by the device. In one aspect, an interior space includes a plurality of objects having discernable visual characteristics disposed throughout the space. The device captures an image containing one or more of the objects and identifies the portions of the image associated with the objects based on the visual characteristics. The visual appearance of the objects may also be used to determine the distance of the object to other objects or relative to a reference point. Based on the foregoing and the size and shape of the image portion occupied by the object, such as the height of an edge or its surface area, relative to another object or a reference, the device may calculate its location.
