I just had a phone conversation with a guy that sells 3D scanners. He doesn't sell any of the scanners that will do what I want, so he didn't have an axe to grind. He's been in this industry for quite a number of years and according to him, none of the scanners I listed will do what I want.
He suggested the following scanners for doing room scans. None of these are cheap, but they do exactly what I was looking for a scanner to do.
