Camera calibration using a square grid pattern

Hi all,

I'm aware that openCV has inbuilt functions to support camera calibration using,

      1.  Circle pattern - cv2.findCirclesGrid() 
      2.  Chessboard pattern. - cv2.findChessboardCorners()

But my application required to use a square grid pattern as mentioned in this paper Camera Calibration With One-Dimensional Objects.

I would like to know is there any possible way to use openCV inbuilt camera calibration functions directly or alter them accordingly to achieve my requirement.

Any guidance would be appreciated.

Thanks in advance.
