Hello,

I am trying to do http://wiki.ros.org/apriltag_ros/Tuto... 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/documen...

png file is attached below, it will have to be printed considering scale.
