Abstract
A mobile device that is able to locate itself in a topological map using a combination of visual and radio information is provided. The mobile device captures an image of its environment, detects receivable radio transmitters and builds an observation vector that defines visual words and radio words that are present at the current location of the mobile device. It then compares this observation vector to reference vectors corresponding to reference location and identifies, based on correlations between visual words and radio words, the location of the mobile device among reference locations.
