Abstract: Disclosed is a method and a system for 3D modeling of a 3D object adapted to be inserted in or worn by a patient. The 3D modeling applies information of one or more features from an acquired 2D digital representation comprising textural data of the location where the 3D object is adapted to be arranged

Abstract: A method and scanner system for scanning interior surfaces include providing a probe shaped scanner having an axis, the probe shaped scanner includes at least one light source configured to create and project structured light, and at least one camera configured to record 2D images; entering the probe shaped scanner into a cavity of an object, where the cavity is bounded by an interior surface of the object; creating and projecting structured light from the 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 the camera; combining the series of 2D images to obtain 3D real world coordinates of the interior surface; and providing data and processing the data such that surface information for areas of the surface, where image scanning is not complete, is created.

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 an optical coherence tomography scanner and a method for recording sub-surface scans of an object, wherein a position encoder is arranged in the path of the probing beam of an interferometric system. The encoder pattern is detected in a sequence of A scans at generated for different probing beam positions on the scanned object, the probing beam position and/or inclination for at least one A scan of said sequence of A scans is deducing based on the detected encoder pattern, and the sub-surface scan of the object is generated based on the sequence of A scans taking into account the deduced probing beam position and/or inclination.
