Build Your Own 3D Scanner: Optical Triangulation for Beginners. 3D Scanning using Swept-Planes The goal of this project is to build an inexpensive, yet accurate, 3D scanner using household items and a camera.
Specifically, we describe how to implement the "desktop scanner" originally proposed by Jean-Yves Bouguet and Pietro Perona, composed of five items: a camera, a point-like light source, a stick, two planar surfaces, and a checkerboard. By waving the stick in front of the light source, the user can cast planar shadows into the scene. Build Your Own 3D Scanner: Optical Triangulation for Beginners.

I was about to embark on finally fixing my homemade structured light implementation (created in a Computer Vision class), when I stumbled across this amazing site.
Recently at SIGGRAPH 2009 there was a course on 3D scanning with structured light. I wasn’t able to make SIGGRAPH this year because I was working at Walt Disney Imagineering, so I didn’t find out about this course until this week.
