A calibration cradle for a three-dimensional scanner, the calibration cradle comprising:

• 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,
• wherein the movement driver comprises:
• a case mover configured to vertically move the movable case;
• and
• a pattern mover configured to rotationally move the pattern plate, and
• wherein when the case mover and the pattern mover stop, the camera operates to conduct calibration, and at least one of the case mover or the pattern mover moves.
