Abstract: The present disclosure relates to a 3D scanner system comprising an intraoral scanner comprising: an elongated housing comprising a distal end for being inserted into an oral cavity, wherein the housing comprises an aperture in a sidewall of the distal end of the housing; and a window arranged in the aperture of the housing; and/or a sleeve mounted on the outside of the elongated housing; the 3D scanner system further comprising one or more processors operatively connected to the intraoral scanner, said processors configured to receive one or more two-dimensional images comprising a plurality of pattern features, wherein the images comprises one or more artifacts arising from reflections from the window and/or sleeve; and provide the two-dimensional image(s) as input to a parameterized model trained to determine the position of at least a subset of the pattern features in the image(s), while suppressing or ignoring the artifacts.

Abstract: The present disclosure relates to a scanning system for generating a three-dimensional (3D) representation of an object, the scanning system comprising: an intraoral scanning device comprising one or more projector units configured to project a pattern on a surface of the object; two or more camera units configured to acquire a set of images comprising at least one image from each camera unit, wherein each image is composed of an array of pixels, wherein each pixel comprises a pixel color defined by one or more color channels; wherein the scanning system further comprises one or more processors configured for: determining points in three-dimensional (3D) space that form a solution to a correspondence problem associated with the set of images, wherein the points are determined by comparing pixel colors with computed colors associated with camera rays corresponding to each pixel; and generating the three-dimensional (3D) representation based on the determined 3D points.
