c++ - Calibrated my camera using OpenCV. How do I apply the coefficients in output xml to my future projects -

after calibrating camera using "chessboard" method. how implement/make use of results given in output xml file subsequent code? i'm not quite sure next step entails.

from opencv docs, referring coefficients outputted in xml file:

add these values constants program, call initundistortrectifymap , remap function remove distortion , enjoy distortion free inputs cheap , low quality cameras.
