Abstract: A method and apparatus for generating a color mapping for a dental object. The method includes generating a transformation matrix according to a set of spectral reflectance data for a statistically valid sampling of teeth. Illumination is directed toward the dental object over at least a first, a second, and a third wavelength band, one wavelength band at a time. For each of a plurality of pixels in an imaging array, an image data value is obtained, corresponding to each of the at least first, second, and third wavelength bands. The transformation matrix is applied to form the color mapping by generating a set of visual color values for each of the plurality of pixels according to the obtained image data values and according to image data values obtained from a reference object at the at least first, second, and third wavelength bands. The color mapping can be stored in an electronic memory.

Abstract: An image processing system is used for dentistry. Upon creating a false tooth of a patient (59), a plurality of illuminating light of LEDs with different wavelengths emit light and a photographing apparatus (1A) photographs a tooth portion of the patient (59), thereby obtaining image data. The image data is sent to a dentistry filing system (2A) serving as a processing apparatus, and color reproducing data is obtained by calculation. The color reproducing data is sent to a dentistry factory (55) via a public line. Data is searched from a database (56) for calculating a ceramic compounding ratio, compound data of the ceramic false tooth is obtained, matching the color of the tooth portion of the patient (59), and the false tooth approximate to the tooth color of the patient (59) is created.

Abstract: A method and apparatus for obtaining a color mapping of a dental object. Illumination is directed toward the object over at least first, second, and third wavelength band, one band at a time. An image of the dental object is captured at each wavelength band to form a set of images of the dental object. For pixels in the captured set of images, an image data value for the pixel corresponds to each of the wavelength bands and calculates interpolated image data values proportional to the spectral reflectance of the dental object, according to the obtained image data values and according to image data values obtained from a reference object at the wavelength bands. Spectral distribution data for a viewing illuminant is obtained and the visual color of the dental object reconstructed according to the calculated interpolated image data values and the obtained spectral distribution of the viewing illuminant.

Abstract: A device (100) for determining the surface topology and associated colour of a structure (26), such as a teeth segment, includes a scanner (100,1525) for providing depth data for points along a two-dimensional array substantially orthogonal to the depth direction, and an image acquisition means (68) for providing colour data for each of the points of the array, while the spatial disposition of the device with respect to the structure is maintained substantially unchanged. A processor (24) combines the colour data and depth data for each point in the array, thereby providing a three-dimensional colour virtual model of the surface of the structure. A corresponding method for determining the surface topology and associated colour of a structure is also provided.
