I think I solved the issue. The problem was that I have to enter the number of rows and columns of my Checkerboard in your code manually at line: Here (6,8) means 6 rows and 8 columns

Camera-Calibration/calibration_GUI.py

Line 196 in f368711

ret, corners = cv2.findChessboardCorners(gray, (6,8), cv2.CALIB_CB_FAST_CHECK)

and at this line

Camera-Calibration/calibration_GUI.py

Line 199 in f368711

cv2.drawChessboardCorners(image, (6,8), corners, ret)

I also changed the number of columns and rows on thins line:

Camera-Calibration/calibration_GUI.py

Line 29 in f368711

self.points_in_row, self.points_in_column = 8, 6

To change the Square size according to my checkerboard. I think I have to enter the size in this line:

Camera-Calibration/calibration_GUI.py

Line 30 in f368711

x, y = 30.0, 30.0

is the x, y is the size of checkerboard squares (in millimeters)?

Am I right?

  • And should I specify the resolution of my image frame (e.g 640x480) manually in the code or the code gets the resolution itself?
  • And the last question, is there any other place (other than the places I mentioned above) in code where I have to change the rows and columns value of my checkerboard?

I have updated the code of the calibration_GUI.py file and submit a pull request having some changes where I applied configuration variables for custom Checkerboards. Please check that and if It is OK then merge it thanks.
