Apriltag2 or 3?

[TurtleZhong]

Hi, Thanks your great project. Recently I wanna use ouster lidar(os1-64) to detect tags, But I got a few problems.

1. In README we provide tag16h6c5 from AprilTag3 with three sizes (0.61, 0.85, 1.2)., The size means t in the below picture?
2. I check the AprilTag3 here but I found it is not the same in your paper, also in your provide bags. The tag 0 and tag 4 in apriltag3 (tag16h5) is not the same with above picture. so I check the code betwen lidartag here and apriltag here, I found that your file is the same with apriltag2 here but not 3. but I found your provide tags is apriltag3. so I'm a little confused about that which apriltags to use.

   The tag 0 and tag 4 in  apriltag3 (tag16h5) is not the same with above picture. so I check the code betwen lidartag [here](https://github.com/UMich-BipedLab/LiDARTag/blob/release/src/tag16h5.cc) and apriltag [here](https://github.com/AprilRobotics/apriltag/blob/master/tag16h5.c), I found that your file is the same with apriltag2 [here](https://github.com/shijiwensjw/apriltags2_ros/blob/master/apriltags2/src/tag16h5.c) but not 3. but I found your provide [tags](https://drive.google.com/drive/folders/1Twx7y6yxr-s2qAoCa4XliCxNuINAlXNn) is apriltag3. so I'm a little confused about that which apriltags to use.

I don't seem to have found the April tag image for tag16h6. Where do I need to generate it? Can we still directly test and verify using the image of tag16h5 from Apriltag3?

Hello, I printed the tag for 16h5 with ID 0. As shown in the figure, but I cannot recognize this ID when running the program.
