Wow - how does it do that?! Image recognition techniques alone (as far as I know) couldn't do that, right? So how does it know how far away something is?

- rsp1984 9y agoMy guess is they estimate one or several dominant scene planes from the sparse triangulated feature points and get scale through incorporating accelerometer measurements.
