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.
