Years ago I tried hacking something together like this - primarily to read labels on packaged food products - but the primary roadblock I hit was with the FOSS OCR solutions not being anywhere near good enough to be reliable. Mind you this was a few years ago and I was primarily testing with pytesseract. I would be curious if this team actually used the Google OCR API or an internally tuned one that isn't GA, and how that differs FOSS Tesseract.
