Original Abstract Submitted
A system includes a scanner comprising a light source to emit light onto an object, and an image sensor to form a sequence of images of the object under a plurality of different conditions. The system includes a computing device to perform a calibration of the scanner by determining, from the sequence of images, differences in measured coordinates for a plurality of points on the object under the plurality of different conditions, generating or updating one or more compensation models that compensate for inaccuracies of the intraoral scanner based at least in part on the differences in the measured coordinates for the plurality of points of the object between the plurality of different conditions, and storing the one or more compensation models. The one or more compensation models cause the intraoral scanner to be a calibrated intraoral scanner.
