1D/2D Barcodes with Camera (Micro QR, Semacode, etc.)

[Greg McKaskle]

The NI Imaq libraries do several types of barcodes. If you have LabVIEW installed, you can open up and run an example from Program Files/National Instruments/LabVIEW 8.5/examples/vision. I suspect there are C examples installed, but I'm less certain of where -- probably in the Program Files/National Instruments/Vision folder.

Finally, perhaps the best way to interact is to launch Vision Assistant, bring in an image with the barcode, and in the menu system experiment with the barcode blocks to see how well they work. If you get it to work there, you can either recode it by hand in LV or C, or you can generate code.

As for whether these are good target codes. It is something that has potential, and is certainly use in real world to give computers ways of identifying things moving by. On the other hand, most of these systems have a good guess as to where in the scene will contain the barcode.
