I work in the CV industry and this was a very badly kept secret. There is absolutely no financially feasible way to run something like this with current CV
I work with ML CV industrial systems, and they can certainly do accurate and detailed analysis and identification very quickly. The systems that do this are also necessarily very, very expensive -- much more expensive than any grocery store could possibly justify.
Of course, costs change with time, but right now I don't see how this sort of application could approach being financially feasible.
