Description
There should be a way to use findCirclesGrid() without knowing the pattern size.
This will be useful to detect or at least give a proposition for the user what is
the size of an unknown grid from a single frame. After the size is determined, the
calibration can proceed as before on multiple frames.
I have looked in the latest source code for the symmetrical circle grid. The
implementation first detects the grid and then checks if it matches the pattern
size. If it doesn't just rejects it. So for an unknown size this restriction
should be removed and the detected grid should be returned.

I agree that such a feature could be useful but the pattern size is used a lot internally in the detection algorithms. Yes, we have the final check of the pattern size but former detection will not work out of the box in case of unknown pattern size. So this is not so easy to implement with current algorithms.
