harikreshna:
hope you can help me with my project, its about long-range bar code reader using video camera not laser :-[ code39 will be consider.  Can you give me any ideas on how can i finish my project? please send me any kind of reference that could help.. thanks guys

mikeselectricstuff:
OpenCV vision library may be a good start

joelby:
You could try looking at open source QR code readers to see how they work.

saturation:
Many decoders libs read jpgs and other image files.  Just make a regular camera that can zoom into the code, take an image, preferably not so lossy or loss less [ i..e, png] as to distort it, then pass it to the free routines.
