<p>A simplified method and related apparatus are described for determining the location of points on the surface of an object (12) by varying, in accordance with a unique sequence (16), the intensity of each illuminated pixel directed to the object surface, and detecting at known detector pixel locations (26) the intensity sequence of reflected illumination (22) from the surface of the object whereby the identity and location of the originating illuminated pixel can be determined. The coordinates of points on the surface of the object are then determined by conventional triangulation methods.</p> |
