Method and apparatus embodiments can generate a volume fluorescence image of a tooth. Method and apparatus embodiments can project structured light patterns onto a tooth and generate a contour (volume) image of the tooth surface from acquired corresponding structured light projection images; then acquire one or more fluorescence images of the tooth generated under blue-UV illumination. A composite image that shows fluorescence image content mapped to the generated contour image can be transmitted, stored, modified and/or displayed.

Intra-oral 3-D fluorescence imaging

A method and system for intra-oral imaging using High Dynamic Range (HDR) and highlight removal is presented. The method comprising generating a first High HDR irradiation map of teeth with multiple images captured with different exposures for same intra-oral scene; and removing highlight caused by a specular reflection in a detail-reserved way from the first HDR irradiation map so as to obtain a second HDR irradiation map in which the specular reflection is at least partly suppressed.
