GRAVEYARD
This package is currently in the graveyard until it is ported to work with the new visual odometry libraries. It and its dependencies can be checked out from:

Data files
The place_recognition and visual_odometry packages are research code; apologies if they are difficult to work with in their current form.
To use this package you will need a vocabulary tree trained on a large dataset of images. We have one here: http://vault.willowgarage.com/wgdata1/vol1/jbowman/holidays.tree
This tree was trained on the C-descriptors devised by Michael Calonder (calonder_descriptor). This descriptor has its own training stage which produces a random forest classifier. The classifier used to generate the above tree is available in two ways:
Do roscd calonder_descriptor && make test. This will automatically download the classifier current.rtc to the calonder_descriptor package directory.
Download it directly from http://pr.willowgarage.com/data/calonder_descriptor/current.rtc
