Not very well. Nor very quickly. Especially if you mean using cameras
rather than something like a laser scanner.

Absolutely.

True, but not from lack of trying. In other words, it's a very complex
problem in the general case, and a lot of work has been done towards
solving it. An excellent area for doing research, but I'd suggest you start
be reading up on current state-of-the-art.

Good luck!
