Custom fiducial markers?

[Jones-S]

Is there a way to include custom fiducial markers? How are they implemented and why do the current ones look like they do right now.
I know this project is kinda not maintained, but maybe somebody is still keen to answer.

Hi,
maybe this article can be useful to understand how fiducial markers are designed

Perfect. Thank you, I will have a look at that.
