We've recently been looking into laser scanning the interior of a building. The options out there are interesting, but in many cases very time consuming, especially if you have lots of rooms. If you have a big open space, then it's much easier, less time consuming therefore cheaper.
I ran across this youtube video today that I thought I would share. No, we're not doing this. At least not yet!
