Method and apparatus for determining the appearance of an object
First Claim
1. A method for determining the appearance of an object comprising the steps of:
- illuminating a surface of the object with a controlled illumination;
collecting, with a camera, color shade data corresponding to light rays reflected from a predetermined plurality of points on the illuminated surface of the object; and
processing said color shade data to create at least one appearance map of the object.

Abstract
A method for determining the appearance of an object to be replicated and an apparatus therefor are described herein. The method consists in providing a controlled illumination to illuminate a surface of the object, measuring the object with a CCD camera to collect an image map of a plurality of points on the surface and processing that information to produce an appearance mapping of the object. Calibration of the apparatus is done by measuring calibration patches illuminated with the same illumination. When the apparatus is made in view of replicating the appearance of an object, a comparison can be done by similarly producing an appearance mapping of the replicate and by comparing it to the appearance mapping of the object.

28. An apparatus for determining the color of an object, said apparatus comprising;
-
an illuminator assembly to produce a controlled illumination onto a surface of the object;
said illuminator assembly including at least one light generating source and at least one illumination path between said at least one light source and said object to project said generated light on the object;a camera to collect light reflected from a plurality of points on the surface of the illuminated object;
said camera producing a first set of data consisting of a spectral image map of the illuminated surface of the object;a controller to control said at least one light source and said camera and to process said first set of data to create at least one appearance map of the illuminated surface of the object. - View Dependent Claims (29, 30, 31, 32, 33)
