Patent abstract
An indoor wayfinding application operates to generate pathway instructions based on knowledge about a mobile device user orientation, a starting location, a destination location and based upon knowledge of spatial inter-relationships and dimensions of enclosed spaces in a building. The user orientation is determined by an image comparison algorithm operating on a query image captured by a camera and a reference image, and the starting location is determined by comparing the query image to a plurality of reference images, each one of which is at a known location, for a best match.
