This repo contains an PyQT app that allows modifying the different distortion coefficient used by OpenCV and get a live undistortion of a target image. It can be useful to fine tune some parameters but is not meant for a full calibration as the parameter space is way too big. I can recommend RTBMap and the calibration tool present in the Settings for an initial guess.
You will first need to place a picture to undistort in the same folder under the name image.png.
It is possible to specify intial distortion parameters directly in the python file.
