[ptx] Any need for automatic batch correction of barrel and pincusion distorsion?

[Mattias]

Hi!

I have made a quick hack to automatically correct barrel and pincusion 
distorsion in images taken by a digital camera.

The concept is simple:
1: Read the EXIF tag embedded in the image.
2: Use the tag "FOCAL LENGTH" to pick a set of correction parameters 
from a correction table specific for the camera/lens.
3: Use the parameters to correct the image.

The beauty in this is that it can be done in batch mode. You can take 
200 pictures and feed the images to a script that processes the images 
for you. Since all information needed to correct each image is embedded 
in the image, it is simple. Once you have determined the correction 
table for your camera/lens, of course.

I recently used the hack to correct a large number of images from an 
indoors photo job I did. And it was of great value to me.

Now, I have only made a hack. It is kind of a concept demonstrator. But 
it works great.
It needs further work. It should also consider that object distance 
affects the distorsion somewhat.

I wonder, is there anyone else but me that could find use for this kind 
of program?

I am no wizard in optics... but know some of the physics, and I could 
use some expert tips in the future.

Any suggestions on any other maillists I should post this on?
