Hello,

This is for those who have vast knowledge or a pretty good idea in
camera calibration reports.
I recently aquired a camera calibration report fror use in my project
and the information contained in it is vast. I wish some one out there
with experience in this matter to help me eventually understand and
pull out values for Radial distortion R1,R2, R3 and the tangential
distortions.
These will be important to help me generat a calibration file such as
one below

-------------------------------------------------------------------------
% Camera: Canon EOS 1Ds Mark II
% Lens: 24 mm

Un-orthogonality 0.0001100395153835741600000
-----------------------------------------------------------------------------------

all the values above are expressed in pixels and any one who is
willing to offer advice is welcome to post a msga nd i send them a
copy of the calibration report
Other wise am having a rough time trying to understand all the
complicated photography terms and figures.

Thanks
