AN IMAGE-BASED SYSTEM FOR URBAN NAVIGATION
Duncan Robertson and Roberto Cipolla
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.
If you have difficulty viewing files that end
which are gzip compressed, then you may be able to find
tools to uncompress them at the gzip
If you have difficulty viewing files that are in PostScript, (ending
'.ps.gz'), then you may be able to
find tools to view them at
We have attempted to provide automatically generated PDF copies of documents for which only PostScript versions have previously been available. These are clearly marked in the database - due to the nature of the automatic conversion process, they are likely to be badly aliased when viewed at default resolution on screen by acroread.
