An Image-Based System for Urban Navigation
D. Robertsone and R. Cipolla (Cambridge University)

We describe the prototype of a system intended to allow a user to navigate
in an urban environment using a mobile telephone equipped with a camera.
The system uses a database of views of building facades to determine the
pose of a query view provided by the user. Our method is based on a novel
wide-baseline matching algorithm that can identify corresponding building
facades in two views despite significant changes of viewpoint and lighting.
We show that our system is capable of localising query views reliably in a
large part of Cambridge city centre.
