Abstract
A method of calibrating an intraoral scanner includes irradiating light of a third color using a projector onto a first calibration plate having a background of a first color and patterns of a second color, which are arranged at predetermined intervals within the background; obtaining an image of the patterns with an increased contrast by photographing the first calibration plate with a camera; calibrating the camera by comparing the image of the patterns with actual positions of the patterns; irradiating the first calibration plate with a patterned light having a predetermined pattern of a fourth color using the projector; obtaining an image of a pattern formed by the patterned light of the projector by photographing the first calibration plate with the camera; and calibrating the projector by comparing the pattern image with a target irradiation position of a pattern irradiated by the projector.
