Hi all,
I'm interested in the visual odometry and visual slam. I find some 
packages of visual odometry in ROS.
They are:
Package Visual_odometry in graveyard
Package vslam and vslam_demo in graveyard
Package visodo in wg-ros-pkg/vision in trunk
Are these packages ready for running?
Which in these package can I build for demonstrating how visual odometry 
or visual slam run?

Thank.
