I need to corret for barrel distortion in a number of images, all taken with the same camera at the same distance away from my target. Is a pin hole transform appropriate or will I need to create a polynomial transform? If I need to create a polynomial transfrom, are there any camera/lens calibration data sets availble?

There's some information (and perhaps source code available) here about 
barrel distortion correction:

I also know of some papers which you can download here:

Another excellent tutorial (including some source code) can be found here:
