DAVID-Laserscanner

DAVID-Laserscanner is a freeware software for 3D laser range scanning. All you need to build a 3D scanner is a PC, a camera (a Web cam), a background corner, and a hand-held laser that projects a line onto the object you want to scan. So everyone can use it to scan objects without high costs, this is the big advantage over commercial solutions which are rather expensive.
