Hi,
I have two Zed X Ones (2.2mm) that I plan on using with a baseline of 1.25m
During my first trial calibration, I had them at 45cm baseline and used a A4 calibration pattern with square size 25mm, 9x6 internal edges. The one provided in the calibration readme in zedx-one-capture repository. I tried the calibration 4-6 times and noticed that the best baseline post calibration was reported at 51cm in the .conf file. Which was not really reassuring but I didn’t really mind that coz it was just a test.
Now for the final deployment, i want them to be at 1.25m like mentioned above. I have a calibration board that nearly an A2, with a square size of 105mm and 7x5 internal edges. (This board has no white borders around the outer edges of the chess board, not really sure if that matters). I noticed that the calibration script does not pick up the board at all, I tried this with the calibration board at 2m-5m away from the stereo rig. By this I mean, while the entire board is clearly visible in both the camera’s fov, I don’t see the multi colored lines that appear on the left camera to indicate it’s being detected.
I understand that a bigger board with a lot of squares would make the calibration more accurate. I’m planning on getting a new calibration board and would appreciate it if you could provide the optimal/ ideal parameters for the calibration pattern for my setup (1.25m baseline) (size of squares and number of edges + if I need the white border and how thick)
