WebInstead of chess board, we can use some circular grid, but then use the function cv2.findCirclesGrid () to find the pattern. It is said that less number of images are enough when using circular grid. Once we find the corners, we can increase their accuracy using cv2.cornerSubPix (). We can also draw the pattern using cv2.drawChessboardCorners ().
