Claim One:
1. A method of optically mapping a three-dimensional surface, comprising the steps of: (a) illuminating the surface through a grid structure to produce a grid representation on the surface, said grid representation having intersection points; (b) viewing the illuminated surface with a video camera; (c) producing a video signal in response to said step of viewing; (d) converting said video signal to digital form; (e) storing a frame of said digitized video signal in a frame memory; (f) defining the grid representation on the surface, from, said stored video signal; (g) locating coordinates of said intersection points of said grid representation; (h) determining curvatures of said grid representation at said located intersection points; and (i) three-dimensionally reconstructing the surface from said coordinates and curvatures of said intersection points.
