Abstract: A computer-implemented intelligent alignment method for a color sensing device (12) which initially obtains a raw sense value measured by the color sensing device and converts the raw sense value to a tristimulus value (S401). The color sensing device may be calibrated using a known set of colors (S402). Raw readings received from the color sensing device may be mapped to known tristimulus values (S403), and mapped values may be converted to a standard reference illuminant color space (S404). A client-server system may be provided in which a color sensing device and one or more servers collectively execute operations according to the present disclosure.

Abstract: A dental imaging and illumination device. The device has an optical interface for emitting light from the device and for receiving light into the device. The device has a light source, a camera, a beam splitter and a color reference. The color reference and the light source are optically coupled via an optical path so that the light source can illuminate the color reference. This optical path bypasses the beam splitter. The device facilitates color measuring particularly in the field of dentistry.
