it seems occurs on

And short bag here :)

Hi Yechan, you can update the code to our newest version and try again. I hope there will be no bug for the calibration board detection. However, I noticed that in your provided bag, there were always no points on the background of the circle holes, as shown in the red circle part of this figure. It will cause the failure of circle detection. You'd better adjust the calibration environment. Blank diagram - Page 1

I know that there might be difficulty in recognizing circle over there. It's just an error occurring even before recognition begins.

I tried with newest version again. Process isn't dead but doesn't recognized calib board 😢 https://drive.google.com/file/d/191Te2BRzdSsVpSGJAPyx8rix8kiHyIiL/view?usp=sharing

I tried reconfigure, but didn't work

Is there any possible way?

Hi Yechan, you can try reconfiguring again. Here are the parameters I adjusted and succeeded in board detection. Blank diagram - Page 1

I'm really appreciate for your effort :)
