ABSTRACT:
A system for producing data to represent the three-dimensional shape of a surface including a projector for projecting patterns onto the surface. A sensor for producing representations of selected imaged patterns as projected onto the surface, and a device containing data that represents the relative positions of the projector and the sensor for processing data produced by sensor to generate output data that is representative of the shape of the surface.
