Abstract

The present disclosure relates to a computer-implemented method and an intraoral scanning system. The computer-implemented method for removing a glare defect in a processed image scan data, comprising: receiving a plurality of image scan data of a dental object produced by an intraoral scanner, processing one or more image scan data of the plurality of image scan data into a processed image scan data, wherein the processed image scan data includes a plurality of pixels, determining a plurality of defect pixels in the processed image scan data by a glare detection algorithm, wherein the glare detection algorithm may be configured to determine the plurality of defect pixels, when a pixel value of each of the plurality of defect pixels fulfils one or more pixel value criteria, and, when a geometry of an arrangement of the plurality of defect pixels fulfils one or more geometry criteria, determining, by a glare-removal algorithm, non-glare image scan data by analysing pixels of the plurality of pixels that are in vicinity to the plurality of defect pixels, and replacing the processed image scan data in the plurality of defect pixels with the non-glare image scan data.
