These are the files/code of my camera calib using OpenCV-Python. These code files are not so much organized as I did not find spare time to clean the code or write a good documentation/tutorial.

lib

• opencv 4.5.5
• Pyqt5
• yaml
• Numpy

tab Calib Real time camera calibration tool

Calib matrixes, dist of camera from CHESSBOARD

• Start Button : enable calib
• Detect Corners: enable Corners detect
• IGNORE: IGNORE image
• CONFIRM: use image
• Done : calib with num images take from camera

tab Calib World

• Calib real world (Just XY ) from pixels position
• Use 7 points
• Step1: calculator position of points from realworld
• Step2: calculator position of points from pixel
• detect points Button: detecting a object pixel position,which will help to step2
• calib Button: calib function
