This repository contains multi-camera intrinsic calibration using opencv.
In order to generate the distortion and calibration parametrs, execute cam_cal_dist_mtx_generator.py.
Once mtx and dist parameters are saved, use cam_intrinsic_cal.py to undistort the input images. If not specifying an output folder, the undistorted images will be overwritten on the input images.
To replace the inputs images with undistorted ones, keep the input and output parent directories the same.
