Color measurement with structured light

A color determination system (100) for spatially resolved color determination, comprising

• a first projector (107) for projecting a first structured-light pattern (101-1) of a first wavelength of light onto a dental object (103);
• a first detector (109) for detecting (S102) a first spatially resolved optical parameter set based on a reflected or remitted first structured-light pattern (101-1);
• a second projector (107) for projecting (S103) a second structured-light pattern (101-2) of a second wavelength of light onto the dental object (103);
• a second detector (109) for detecting (S104) a second spatially resolved optical parameter set based on the reflected or remitted second structured-light pattern (101-2);
• and
• a calculator (111) for calculating (S105) a third spatially resolved optical parameter set at a third wavelength of light based on the first spatially resolved and second spatially resolved optical parameter sets;
• wherein the color determination system (100) is configured to adjust a predetermined spectral course to the first spatially resolved and second spatially resolved optical parameter sets to obtain the third spatially resolved optical parameter set;
• and
• wherein the predetermined spectral course is a course of a reflectance, an absorption coefficient and/or a scattering coefficient depending on the wavelength of light.
