Abstract
A method and apparatus for rapid three dimensional geometry parametrization of a three dimensional surface. A random speckle pattern is projected upon the surface and imaged to obtain a plurality of two dimensional digital images. The two dimensional images are processed to obtain a three dimensional characterization of the surface. The illuminated surface may be modeled to obtain a parameter set characterizing the surface based upon the two dimensional digital images.
