Apriltag parameters setting

[deepintoSky]

I only have one April tag, how should I set the parameter april_tag_number_pixel_boarder and april_tag_gap_size_m ? By the way, how can I generate the april tag in your size?

This guide explains the tag setup and generation, https://github.com/ethz-asl/kalibr/wiki/calibration-targets
hope it helps!

Hi, I couldn't find the parameter april_tag_number_pixel_boarder in the wiki you mentioned above. Could you please explain what this parameter means?

@ghoshsuman I think it's the thickness of the black border around each small april tag. If you look at the photo of a calibration board, it has many april tags consisting of black and white pixels. Around each april tag there is a black border. I think this parameter defines the thickness of said border. It would be 2 on most calibration boards I've seen.
