Much appreciation for your sharing this coding. it's useful.
Here i am looking forward for your help

1. As you see the orignal pic, all the apriltags can be checked using pupli_apritags. but aprilgrid can't ,even using the undistored pic.(see the below pic.). meanwhile, very curiously, as your demo shown, the aprilgride board for calibration can be detected well by your code, inversely, pupil_apriltags failed everytime expect the example i show here. So can you help me to anaysize what's reason? meanwhile, in the last pic, this is generated by kablir: tagsize:5m, and ratio is 0.25，it‘s not detected by aprilgrid, can you help debug this?
