The master tag always comes first in the XML file and defines a coordinate system for the rest of the tags.

IMPORTANT: this coordinate system is different from the standard system used in ROS!

For example, this can allow for the estimation of the pose of a many-sided object, even when some of the tags cannot be seen.

It can also lead to more stable pose estimates and provide robustness to occlusion.

A tag bundle is defined by an XML file that lists a set of tag IDs and their positions relative to a "master" tag.

Alvar is significantly newer and more advanced than the ARToolkit, which has been the basis for several other ROS AR tag packages.

Alvar features adaptive thresholding to handle a variety of lighting conditions, optical flow based tracking for more stable pose estimation, and an improved tag identification method that does not significantly slow down as the number of tags increases.

*** NOTICE ***: The issues with Eigen on 32 bit systems that some people experienced have been fixed in the Groovy release and forward.If you want to use a 32 bit OS with an earlier release, see these commits: Two pdf files are in the markers directory containing tags 0-8 and 9-17, respectively.The markers are 4.5 cm (although when printed and measured, came out to 4.4 cm for me).If you want to generate your own markers with different ID numbers, border widths, or sizes, run: The first use case for this package is to identify and track the poses of (possibly) multiple AR tags that are each considered individually.The node individual Markers takes the following command line arguments: individual Markers assumes that a kinect being used as the camera, so that depth data can be integrated for better pose estimates.If you are not using a kinect or do not desire to use depth data improvements, use individual Markers No Kinect instead.
