I couldn’t calibrate my camera until it was flipped 180 on Z.
Following this, it calibrated on first attempt.
Is there still a software analysis component you were working on? detection/correction of camera orientation based on motion analysis?
Obviously, it much easier to just flip the camera in meat-space…
Is this on Linux or Windows? The Linux version should auto detect an 180 degree rotated camera. Both versions detect small rotational errors and compensate for them
