    Abstract: The present invention relates to non-contact optical scanning of an object for generation of a three-dimensional surface model of the scanned object. In particular the invention relates to a scanner for obtaining the three-dimensional geometry of at least a part of the surface of an object, said scanner comprising: - at least one light source, preferably a laser light source with adjustable power, - projection means for directing light from the at least one light source to a moving spot on the surface of the object, - at least one image sensor adapted to record at least one image of at least a part of the surface, - detection means, other than the at least one image sensor, for monitoring at least a part of the light reflected from the surface, - regulation means for adjusting the intensity of the at least one light source based on the amount of light reflected from the surface, and - means for transforming the at least one image to a three-dimensional model of the surface.

    Abstract: Disclosed herein is method for generating a digital 3D representation of at least a part of an intraoral cavity, the method comprising:
    - recording a plurality of views containing surface data representing at least the geometry of surface points of the part of the intraoral cavity using an intraoral scanner, wherein the surface data also comprises color information;
    - determining a weight for each surface point at least partly based on scores that are measures of belief of that surface point representing a particular type of surface;
    - executing a stitching algorithm that performs weighted stitching of the surface points in said plurality of views to generate the digital 3D representation based on the determined weights; and
    - wherein the scores for the surface points are found by at least one score-finding algorithm, wherein the at least one score-finding algorithm is a machine-learning algorithm trained on color images.

    Abstract: Disclosed is a method for planning, visualizing, and/or optimizing dental restoration on at least a part of the pre-prepared teeth of a patient, wherein said method comprises the steps of:
    - providing at least one 3D digital model of at least a part of the pre-prepared teeth;
    - designing at least one dental restoration CAD model based on the 3D digital model of at least a part of the pre-prepared teeth;
    - providing at least one 3D digital model of at least a part of the prepared teeth, where the prepared teeth are provided by preparing the pre-prepared teeth by dental restorative work, at least partly based on the dental restoration CAD model; and
    - aligning the 3D models of the pre-prepared and the prepared teeth.

    Abstract: Disclosed is a structured light 3D scanner based on the principle of triangulation with a light source for generating a light pattern, two cameras with two-dimensional sensors recording the reflection of the light pattern from a target object, and one axis moving the cameras. Wherein the cameras are arranged with at least partly overlapping fields of view and where the sensors in the cameras are read out partially and concurrently during at least some period of the scanning process, thus providing partial images and where the partial images are merged prior to performing the triangulation calculations.
