Structured Light Turntable Scanner

Structured light scanning is fast, accurate, and provides surface modeling as well. Professional scanners can mix Laser information with Digital images using photogametry. It is performed with a projected image of changing contrast squares that register curves and distortions from the 3D object being scanned. Once calibration is made with a camera then the two tied together can be moved around for 3d images, or better yet a turntable rotates in front of the camera projector pair a few degrees for each scan. Commercial photogametry software like DAVID scanner is available for trial, there are open source programs as well. The open source program Meshlab allows for alignment of the multiple scans to build a 3d object manually. A turntable controlled by an Arduino inteface to the Scanning program makes a professional method of high resolution scanning. After tinkering with several methods out there the following build is recommended.
