Calibration not possible?

[fzoric8]

Hi,

I'm trying to do depth calibration of OAK-D-W-PRO-POE camera.

I've downloaded checker board for 50 inch screen and put it onto the 50 inch screen. I've
measured the checker size and it can detect checkerboard with RGB camera, and right camera.
However, left camera can't consistently detect checkerbord.

When I try to capture image, I'm getting following output:
Checkerboard couldn't be detected (or something similar).

I'm not able to detect checkerboard with my left camera which is troubling me.

Depth is really, really bad, and I can't work with depth like that, so I need to recalibrate it.

Here are images of the 1st calibration step (Checkerboard in the camera FOV).

Let me know what to do.
Thanks!
