Abstract: The present invention relates to a calibration cradle for a three-dimensional scanner. Particularly, the calibration cradle comprises: a cradle body into which a front end portion of a three-dimensional scanner is inserted and seated; a calibration pattern plate (hereinafter, abbreviated as “pattern plate”) which is disposed inside the cradle body to correct the scanning of the three-dimensional scanner; and a pattern movement part which automatically axially rotates and axially reciprocates the pattern plate in the cradle body when the three-dimensional scanner is coupled to the cradle body, whereby the present invention provides an advantage of improving the convenience and reliability of performing calibration.

Abstract: The present disclosure relates to a calibration cradle for a three-dimensional scanner. In particular, the calibration cradle includes: a fixed case having an internal space formed therein; a pattern plate provided inside the fixed case and provided to calibrate the three-dimensional scanner comprising a camera; a movable case into which at least a portion of the three-dimensional scanner is inserted such that the camera faces the pattern plate, the movable case being configured to move to allow the three-dimensional scanner to move by at least one of rotational movement or vertical movement; and a movement driver configured to provide a driving force to move at least one of the movable case or the pattern plate. The calibration cradle provides an advantage of improving the reliability of calibration and user convenience.
