    Abstract: The present disclosure provides a computer-implemented method for correlating at least one 2D-image to a 3D-representation of at least a part of a tooth displayed in a graphical user-interface, of a hand-held scanning device, on a screen, comprising the steps of obtaining a first set of 2D-images of the at least part of the tooth based on illuminating the tooth with light in the visible domain; forming a 3D-representation of the at least a part of the tooth from the first set of 2D-images; displaying, in the graphical user-interface, the 3D-representation; obtaining a second set of 2D-images based on illuminating the tooth with light in the infrared (IR) domain; displaying, in the user-interface, a manipulator; and based on input as associated to the manipulator, displaying a desired 2D-image correlated to a desired location on the 3D-representation, wherein the correlation is calculated once the manipulator is positioned at the desired location on the 3D-representation.

    Abstract: Disclosed is a 3D scanner system for detecting and/or visualizing cariogenic regions in teeth based on fluorescence emitted from said teeth, said 3D scanner system comprising: a 3D intraoral scanner comprising: an illumination unit configured for providing probe light for illuminating the teeth, the illumination unit comprising: a first light source configured to emit light at a first wavelength; and a second light source configured to emit light at a second wavelength; wherein the 3D intraoral scanner is configured to shift between the two light sources repeatedly such that the teeth are illuminated successively by the light from the first and the second light source; an image sensor for recording images of light received from the illuminated teeth; the 3D scanner system further comprising one or more processing units configured for: creating a digital 3D representation of the surface of the teeth based on recorded images comprising probe light reflected from the teeth.

    Abstract: Disclosed is a method and a scanner system for scanning interior surfaces, where the method comprises: - providing a probe shaped scanner having an axis, where the probe shaped scanner comprises: • at least one light source configured to create and project structured light, and • at least one camera configured to record 2D images; - entering said probe shaped scanner into a cavity of an object, where said cavity is bounded by an interior surface of the object; - creating and projecting structured light from said light source of the probe producing a pattern on the interior surface of the object; - recording a series of 2D images of the reflection of the pattern from the interior surface using said camera; - combining said series of 2D images to obtain 3D real world coordinates of the interior surface; and - providing data and processing said data such that surface information for areas of the surface, where image scanning is not complete, is created. The scanner system may comprise a probe shaped scanner, a data conversion device and a data processing device, optionally all integrated in one device. (fig.15 should be published)
