The bachground of the question is that the barrel distortion

some time ago (partly due to my request) and the IM community now
needs an easy way to determine lens parameters in order to make this
functionality useful.

The tutorial method is only really stable with lots of lines in the 
scene (or multiple photos).

The same system was developed into a command-line tool in this 
year's summer of code - calibrate_lens is part of the Hugin 2009.4.0 
release: http://hugin.sourceforge.net/releases/2009.4.0/

This tool does exactly what you want, but needs some documentation 
to be usable.

If that is the only reason for my problems, it should probably be
mentioned exactly on that page... I lost hours by trying to reproduce
the example :-(

This sounds very promising. Unfortunately, I am using Hugin under
Windows and there doesn't seem to be a binary installation package for
the newest Windows version yet (?). The newest version with a Windows
installation package I could find was 2009.2 and this doesn't seem to
contain a program with the name mentioned by you (?).

Anyway, I would need some kind of tutorial in order to use that package
I guess. I would be even willing to write one (in English), if somebody
would support me in doing so.
