DESKTOP THREE-DIMENSIONAL SCANNER FOR DENTAL USE PROVIDED WITH TWO-AXIS MOTION UNIT IN WHICH CAMERA AND PROJECTOR ARE COUPLED TO UNIT FOR CHANGING HORIZONTAL AXIS OF ROTATION OF STAGE

摘要

In a desktop three-dimensional scanner for dental use of the related art, a two-axis rotation motion unit, on which a target object can be placed and rotated in order to image the entire shape of the target object, is coupled to the scanner, and thus, when a subject is placed on the imaging stage and is rotated along the horizontal axis of rotation of the stage, the subject is dropped from the stage by gravity after being inclined, and accordingly, additional fixing means or a receiving jig should be placed on the stage together with the subject to prevent same. In such a case, inconvenience is caused because the target objects to be scanned have various shapes and the fixing means or receiving jigs should fit the shapes thereof. According to one embodiment of the desktop three-dimensional scanner for dental user of the present invention, a camera and a projector are provided on the unit for changing the horizontal axis of rotation of the imaging stage, and thus a target object does not have to be inclined during the scanning process and dental prostheses of various shapes can be three-dimensionally scanned even without additional fixing means or a receiving jig.
