DIY 3D Laser Scanners

Unlike the delta robot that I currently have no practical use for, I could use a 3D laser scanner.

The structured light approach to 3D scanning looks like it might work for producing a high resolution scan. Failing that another approach might be to build a DIY version of this, or maybe I should just build the delta robot as a 3d contact scanner.
