Abstract: Disclosed is a 3D scanning system and a method for using such a system, where a handheld scanner of the 3D scanner system is used to control the operation mode of the system such that the user does not need to engage an external unit e.g. during a scanning procedure in which the teeth in a patient's upper and lower jaws are scanned.

Abstract: A 3D scanner system includes a scanning device capable of recording first and second data sets of a surface of an object when operating in a first configuration and a second configuration, respectively. A measurement unit is configured for measuring a distance from the scanning device to the surface. A control controls an operation of the scanning device based on the distance measured by the measurement unit, where the scanning device operates in the first configuration when the measured distance is within a first range of distances from the surface and the scanning device operates in the second configuration when the measured distance is within a second range of distances; and a data processor is configured to combine one or more first data sets and one or more second data sets to create a combined virtual 3D model of the object surface.

Abstract: A method of aligning two 3D digital representations of at least a part of each of the upper and lower jaw of a patient, the method including segmenting the 3D digital representations to determine the shape and position of each of the patient's teeth in each of the 3D digital representations; and using a set of known anatomical concepts to constrain the fit of the two 3D digital representations to get a preliminary fit.

Abstract: The present disclosure relates to an intraoral scanning device including a light source configured for emitting light; a beam splitter configured for outputting linearly polarized light of a predefined orientation, wherein the beam splitter is arranged such that light from the light source is transmitted through the beam splitter; an image sensor configured for acquiring one or more images; and a light absorbing unit for minimizing stray light on the image sensor, said light absorbing unit arranged on a surface of the beam splitter. The present disclosure further relates to an optical system for an intraoral scanning device, said optical system configured for minimizing stray light in the system.

Abstract: Disclosed is a method for compensating for motion blur when performing a 3D scanning of at least a part of an object by means of a 3D scanner, where the motion blur occurs because the scanner and the object are moved relative to each other while the scanning is performed, and where the motion blur compensation comprises: —determining whether there is a relative motion between the scanner and the object during the acquisition of the sequence of focus plane images; —if a relative motion is determined, performing a motion compensation based on the determined motion; and —generating a 3D surface from the sequence of focus plane images.
