rectangle instead of square for camera calibration
2 views (last 30 days)
I need to use a big checkerboard (36x36 in) for camera calibration with wide angle lens camera.
However, checkerboard is not perfectly square. The size of the square is x = 67.7 mm and y = 67.9mm.
My question is can we use the rectangle size x and y to do the calibration simply modify the code
worldPoints = generateCheckerboardPoints(boardSize, squareSize) to accommodate x, y?
