This is pretty cool. About 6 years or so ago there was a company called Dimensional Photonics that pioneered some of this technology. I worked with them a little bit when they were running out cash, as I was looking to lease some office space at the time and introduced them to a potential VC in the area. In the end, I believe their IP ended up getting sold and the company itself folded. But it was cool to see how they could do a complex scan of something like a car door in about 1 minutes and have super-precise measurements.
