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.

Abstract: The present disclosure relates to an apparatus and method for generating a virtual model. The apparatus according to the present disclosure comprises: a scanner that acquires a continuous 2D image within a measurement space; and a model generation unit for generating a three-dimensional virtual model by converting the image acquired from the scanner, wherein the model generation unit removes an area from the three-dimensional virtual model according to the reliability of data and generates a final model on the basis of the remaining area.

Abstract: The present invention relates to a method of processing three-dimensional scan data for manufacture of dental prosthesis, the method identifies a position for an implant procedure on the basis of image data for an oral structure, and generates aligned image data by retrieving, from a library, data corresponding to a scan body or an abutment, only a part of which has been scanned, by replacing a part or the whole of the image data with the retrieved data, and by aligning a position and a direction of the image data. By using the method, user can easily identify an oral structure from the image data obtained by scanning partial shape of the scan body or the abutment, and the method provides feedback to the user so that the method guides the user to correct measurement. Therefore, the prosthesis can be manufactured more quickly due to reduced scan time.
