Information Driven Adaptive Range Scanner

A scanner system is configured for acquiring three dimensional image information of an object. The scanner includes a projector, a camera, a graphics processing device, and a processor. The projector projects one of several pre-defined patterns upon the object. The camera captures an image from the object, which is received by the processor. The processor approximates mutual information from the object and the pattern using the graphics processing device, and selects a second pattern for projecting on the object.
