Camera Calibration

[taiwohazeez]

Hello.

This is a new starling 2 drone. I am trying to calibrate the cameras, but it seems difficult. When chess board is placed inside rectangle, the rectangles doesn't fill most times, sometimes, i get detections, sometimes i don't. It took several minutes to get a 40% collection rate. Is the calibration supposed to be this difficult? or is there a technique to this? I have seen the video on the documentation website for this, and it was seamlessly easy. Please let me know if I am doing it wrongly?

Expecting your response soon. Thanks.
