Hello, I tried to calibrate the tracking camera using a 4x7 checkerboard with side lengths of 4 cm. I launched voxl-portal to view the camera calibration overlay. Then I placed the checkerboard in various positions and orientations within the red box overlayed on the tracking camera image. However, the calibration process does not progress. I never receive a green (overlay) box and the process remains at 0%.

What should I do to solve this issue?

Command used:
voxl-calibrate-camera tracking -f -l 0.04 -s 4x7

I followed the calibrate camera instructions from here: https://docs.modalai.com/calibrate-cameras/.

Hello ModalAI Team,

It would be great if you provided an easy way to use a Modal AI drone with a motion capture system (such as Vicon). This feature will be helpful to university researchers that may not be able to fly outside (e.g., due to their proximity to an airport) or are interested in experiments where we need accurate drone positions. This feature could increase your consumer base greatly.
