    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 done in view of replicating the color 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.

An image of the dental object is captured at each wavelength band so as to form a set of images of the dental object. An image data value relating to a pixel in a captured set of images corresponds to each of the wavelength bands, and an interpolated image data value proportional to spectral reflectance of the dental object is calculated according to the obtained image data value and according to an image data value obtained from a reference object at the wavelength band. Spectral distribution data on a viewing illuminant are obtained, and a visual color of the dental object is reconstructed according to the calculated interpolated image data value and the obtained spectral distribution of the viewing illuminant.
