The invention provides a three-dimensional digital scanner which includes a multiple view detector which is responsive to a broad spectrum of visible light. The multiple view detector is operative to develop a plurality of images of a three-dimensional object which is being scanned. The plurality of images are taken from a plurality of relative angles with respect to the object, and the plurality of images depict a plurality of surface portions of the object. A digital processor including a computational unit is coupled to the detector and is responsive to the plurality of images so that it develops 3-D coordinate positions and related image information for the plurality of surface portions of the object. A three-dimensional image of the object to be scanned is thus developed by the digital processor. The data developed includes both shape and surface image color information.

L'invention concerne un scanner numérique tridimensionnel, qui comprend un détecteur multivue qui réagit à un large spectre de lumière visible. Le détecteur multivue élabore une pluralité d'images d'un objet tridimensionnel qui est scanné. La pluralité d'images est prise à partir d'une pluralité d'angles relatifs par rapport à l'objet, et elle décrit une pluralité de parties de surfaces dudit objet. Un processeur numérique, qui comprend une unité de calcul, est couplé au détecteur et réagit à la pluralité d'images de façon à élaborer des positions de coordonnées tridimensionnelles et des informations image associées, qui correspondent à la pluralité de parties de surfaces dudit objet. Une image tridimensionnelle de l'objet à scanner est ainsi élaborée par le processeur numérique. Les données élaborées comprennent des informations image couleur portant à la fois sur la forme et sur la surface.
