Image based tracking in augmented reality systems

Abstract:

Systems and methods for image based location estimation are described. In one example embodiment, a first positioning system is used to generate a first position estimate. A set of structure facade data describing one or more structure facades associated with the first position estimate is then accessed. A first image of an environment is captured, and a portion of the image is matched to part of the structure facade data. A second position is then estimated based on a comparison of the structure facade data with the portion of the image matched to the structure facade data.
