A Qt5 GUI to simplify the camera calibration process using OpenCV
The software allows to create a camera model from scratch or to refine the parameters of a model previously calculated.
The calibration process is "Real Time", you can see how the "undistorted" image changes during the calibration/refine process for each Chessboard detected, so you can evaluate the correctness of the whole process while advancing.
The software support the "standard" Pinhole Camera Model (using 8 distorsion parameters) and the FishEye model for camera with optics with a FOV bigger then 140°
