Don't want to hijack this thread as it is a really good one but I looked into the structure scanning sensor. It relies on knowing where it is by using the accelerometers and gyros in the Apple device. Those things are there for games and making sure the window is aligned with the device etc. They are not ultra high precision sensors like you find in a military aircraft nor were they intended to be.

Gyros measure angular rates and accelerometers measure linear acceleration. To turn those into angles and position it has to do a bunch of math and any errors add up over time. So i think the resulting accuracy would be suspect and one would have to tweak and stretch the image to fit some known dimensions. Also, it doesn't work with shiny objects very well.

So if you lay down your money and expect to be able to effortlessly scan a car in 5min with perfect accuracy you might be disappointed.
