I believe I recall my manager at a previous company
telling me that she had previously worked with the guy
who invented that tricky method of using a 2D grid
of printed dots to encode data, as employed by UPS
(among others?) to track packages. I think she told
me that the technology was surprisingly sophisticated
and that it involved (among other things) doing
FFTs on a sample of reflected light gathered from
the dot array. The resultant transform is somehow
(after other tricky steps) reliably mapped to a long
string of digits with good error detection/correction
characteristics, and it apparently doesn't care much
about the orientation of the scanning wand, either.
If I had to bet, it would be that you're unlikely to
find anything nonproprietary that will help you work
with such codes, though I'd be happy to learn that
I'm wrong. Happy hunting...
