摘要： PROBLEM TO BE SOLVED: To provide a method and an apparatus for generating color mapping relating to a dental object.SOLUTION: The method includes a step of generating a transformation matrix according to a set of spectral reflectance data on a statistically valid sampling of teeth. The dental object is illuminated over at least first, second and third wavelength bands, that is, over each wavelength band at a time. An image data value corresponding to each of the at least first, second and third wavelength bands is obtained for each of a plurality of pixels in an imaging array. A set of visual color values relating to each of the plurality of pixels is generated according to the obtained image data value and according to an image data value obtained from a reference object at the at least first, second and third wavelength bands. Thus, the transformation matrix is applied to form color mapping. The color mapping can be stored in an electronic memory.

摘要： PROBLEM TO BE SOLVED: To provide a method and an apparatus for obtaining color mapping of a dental object.SOLUTION: The object is illuminated over at least first, second and third wavelength bands, that is, over each wavelength band at a time. 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.

摘要： A method for mapping a sensor pixel array to an illumination pixel array according to a surface forms a group mapping by assigning each pixel to a corresponding group, each group with p adjacent pixels on the illumination array and each ordered set having k groups, by projecting and recording a sequence of group index images. Each group index image has, in at least two of the groups, no illuminated pixels and in fewer than (k−1) groups, from 2 to (p−1) adjacent illuminated pixels. The sequence of group index images uses pixels from each of the k groups. At least p multiline images are projected and recorded, wherein each multiline image projects a line within each group. Lines in the multiline images are correlated according to the group mapping and the correlation stored in memory. Integers k and p are greater than or equal to 3.
