Hi!
I have troubles getting the calibration board detected during camera calibration. Most of the time no frame is captured during the automatic mode. Am I doing something wrong?
Thanks

Re: Can't detect calibration board
Hi Carlos
There are a few reasons that could prevent a detection:
* Low image contrast
* The pattern is outside of the visible range for one camera
* At least one circle of the pattern is occluded
* The pattern is too far away
* The pattern is very unevenly illuminated (e.g. a strong shadow on the pattern)
* The calibration pattern has the wrong geometry
If you keep on having problems, please post a picture of the calibration interface where we can see the calibration pattern. That would allow me to give you better feedback.

Re: Can't detect calibration board
Thanks, I got it working now. Seems like the pattern was too close to the camera and the right camera didn't see one column of circles.
