Camera Calibration issues

[taiwohazeez]

Hi modal AI support,

I am trying to calibrate my starling 2 drone camera using openCV 6x8 chessboard (I used this command " voxl-calibrate-camera tracking_front -f -s 6x8 -l 0.038". I think my camera lens might be dull, I have a starling 2 Lens Focus Tool, but I can't find any resource to help me adjust the focus. I have attached an image of me me trying to calibrate the camera so that you clearly understand what I am trying to say. From the first image, you can see how blurry the chessboard is, In the second image, you can see that the chessboard is barely showing when the chessboard was moved inside the rectangle. The third image are what I saw in the starling 2 Lens Focus Tool.

Kindly assist.

Thanks,
Taiwo
