excuse my poor english
large frame image taken from DMC camera (intergraph ) is a virtual image from a combinaison of 4 sub images taken from 4 real calibrated camera.
my problem is the inverse : i have the large frame camera with internal and external orientations parameters . i want to subdivide the large image into n subimages taken with n virtuals cameras . what io and eo parameters i use and how to calculate them from the initial io and eo ?
