Real snipers (well, the spotters) look at grass, trees, water ripples and blowing sand along the whole trajectory and factor that into the shot. I don't think our image recognition technology is up to that ability yet. However, this system would basically automate 80% the connection between a ballistics chart ("there's an app for that"), the current conditions, and the scope.
I think the "expert system" that would have to massage any data from the image recognition would be the hard part (not that image recognition is "easy" by any means). I think they're gonna need the human in the loop for a while yet.
