Ref: Free laser scanner software

Definitely, it can be extremely accurate if set up properly and it doesn't
need particularly expensive components. It is very fussy about different
surface types though, clear materials are very tricky apparently. I want to
make one with a camera and 3 laser pointers fixed together and the whole
assembly moving to sit at a fixed distance and directly face-on to a surface.
No real benefits from doing it that way, it gets rid of any inaccuracies in
the camera/laser angle but causes a much bigger pain in the neck calculating
X,Y and Z axis plus 2 rotational axis. Does give predator-like targeting
though :)
