I'm a bit amazed that this kind of data is captured and wonder how accurate it is.
I wonder what the proprietary software is. Anyone know? Based on opencv perhaps? Amazing!
But yes, there is some opencv in this project(and probably in almost every other commercial machine vision project out there), but the smart parts are hand tailored, opencv have useful general purpose algorithms, but to get the best results you need to dig deeper.
