So am I ;-). The sensor(s) are bog plain bw ccd cameras, any camera will
do if it transfers the image in realtime to a pc. I used one attached to a
video digitizer card.

The image processing is another dish. Here is a good book on it:

Algorythms for Image Processing and Computer Vision, J.R.Parker, Wiley, 1997
ISBN 0-471-14056-2 (paperback, with CDROM)

Attached code is in C. The book has nothing to do with barcodes but it
will introduce some of the techniques used. The math gets very complex
after a while and you will have to leave the trail and experiment...

good luck,

Peter
