Maximum number of corners that cornerSubPix() can detect

I have to use a large chessboard to calibrate my camera.
I was using cornerSubPix() but I do not know and can't found the maximum number of corners that OpernCV functions can detect and support.
In fact, I want to know what is the biggest chessboard size to calibrate camera instead of regular 8x8 one.

Any help will be appreciated.

Looking at the source code for cornerSubPix we can see that it iterates up to count which is declared as int. This means you can handle MAX_INT corners, where MAX_INT is the highest number an int can represent.

Practically, you will never have a calibration pattern where this is a limiting factor.
