To state it in short, I really need to understand how the projection and

correction model. Not the calibration, not the exact piece of software. The
model.
I'm not sure what you want.
In the fisheye model the pixel distance from the centre of the image
is directly proportional to the angle from the view axis.
The lens correction model is purely a radial distortion of the
bitmap image, unrelated to the fisheye/rectilinear/etc... projection
and unrelated to any view angles.
This lens correction is normalised to the width or height of the
image whichever is narrowest.
