Images of all tags from all the pre-generated AprilTag 3 families. You can generate your own layouts or images of tags using our other repo, AprilTag-generation.
If the format of the markers is very small (ex : by default, 9x9 pixels), you'll need to rescale them. To do so, you may use the following imagemagick command (Unix) :
convert <small_marker>.png -scale <scale_chosen_in_percent>% <big_marker>.png
