The Hackengineer web site has complete plans for building a portable 3d camera. The system uses a Texas Instruments DLP pico projector, Leopard Imaging’s Leopardboard 365 VGA camera board, a small 2x telephoto lens, and a BeagleBoard. The system uses the concept know as Structured-light. Structured light uses a set of temporally encoded patterns that are sequentially projected onto the scene. When the pattern is seen from different viewpoints, the pattern appears geometrically distorted due to the surface shape of the object. This information is used to construct the depth data.
