Tracking camera calibration not progressing

[Troi]

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/.

@Troi same issue here but with stereo camera and command:

voxl-calibrate-camera stereo_front -s 6x9 -l 0.030

Did you resolve this?
