摘要：
A method for spatially resolved color determination, comprising the steps of projecting (S101) a first structured-light pattern having a first wavelength of light onto a dental object;
detecting (S102) a first spatially resolved optical parameter set based on the reflected or remitted first structured-light pattern; projecting (S103) a second structured-light pattern having a second wavelength of light onto the dental object; detecting (S104) a second spatially resolved optical parameter set based on the reflected or remitted second structured-light pattern; and calculating (S105) a third spatially resolved optical parameter set at a third wavelength of light based on the first and second spatially resolved optical parameter sets.
