apriltag_ros bundle calibration
Hello,
I am trying to do http://wiki.ros.org/apriltag_ros/Tutorials/Bundle%20calibration for apriltag_ros package.
In the tutorial, a calibration page, consisting of 5 markers are shown. Can I find this file as a pdf?
If not, how are the markers are arranged? (the 4 markers on the outside, what is their distance from corner to corner)
Can I just arbitarily lay out any marker arrangement?
Best regards, C.

Hello,
I created a file in gimp that is almost the same as the calibration bundle, shown at http://wiki.ros.org/apriltag_ros/Tutorials/Bundle%20calibration
Before printing, it would need to be scaled, each tag right now is 10x10 pixels.
Also the tag_bundle parameter in the tutorial should be changed. right now, it is not symetric, whereas the one I created is symettric.
I tried attaching xcf file, but answers.ros.org would not accept it, so I put it in a github repo.
Both the png file and xcf file can be accessed: https://github.com/altineller/documentation_images/tree/master/apriltag_ros
png file is attached below, it will have to be printed considering scale.
Best Regards, C.A.
