Hello Tom ,
Have you tried to modify the parameters of the chessboard?
They are in the script 4_calibration.py, you need to modify them according to your chessboard.
Hi - I have similar problem to the one described here initially. I get my camera detected with vcgencmd get_camera, but as soon as I try to run the Motorized_Focus_Camera.py, I get the ENOSPC error. Interestingly - I can click up and down for focus change - but I dont see anything.
Please see images attached for the error messaging and the setup. I ONLY have the Arducam 8MP IMX219 Auto Focus connected to my Raspberry Pi 3 board.
