I am using Python example code and the cheesboard row and column numbers are also correct but somehow I can not get a successful result. I have tested with a lso much of photos below you can see them. My source code: https://github.com/jagracar/OpenCV-python-tests/blob/master/OpenCV-tutorials/cameraCalibration/cameraCalibration.py
