Asking about projector-camera calibration

,
1

Hi i have found projector -camera calibration coding in github

I would like to ask is there any reference by pictures cause i m not sure what kind of photos have to be taken for the projector calibration.( is it fringe projection on it ? )

Because i know it somehow works similar to stereovision calibration which i can capture the checkerboard and detect the corner and put into as image coordinates,

However, im not sure how to get the image coordinates for the projector

Can i have some help
