Where does an Adobe lens correction profile place the principal point (u0,v0) for a 1920x1080 pixel image (width x height), an ImageXCenter of 0.5, and an ImageYCenter of 0.5?
This question concerns placement of the principal point when using an Adobe lens correction profile.
As described in Rectilinear Geometric Distortion Model Descriptors for the Adobe Camera Model (page 13),
Consider a 1920x1080 pixel image, with row & column zero at the upper left of the image. By the definitions above:
Is this understanding correct? Further, would v0 be placed at the bottom of the image (row 960) or the top of the image (row 1080-960 = 120)?
Thanks in advance for the help!
