AR Tag recognition node using ROS

This a test of the ROS tag recognition node publishing the various distances relative to the camera. This camera feed was from the AR drone. The distances that show up are the x,y and z lengths in millimeters. The relative angles are also visible. The tag recognition is done using the ARtoolkit.
AR tags are great for localization. If you know the location of the tags, your location relative to the world can be acquired.
