@psafi Here are the steps I am taking for camera calibration:

1- run the following command:
voxl-calibrate-camera tracking_down -f -s 6x9 -l 0.022

2- look at the overlay in portal (see the screenshot below)
3- calibration process is not progressing automatically even though it seems like the checkerboard is detected
