THREE-DIMENSIONAL INTRAORAL SCANNER AND INTRAORAL SCANNING METHOD USING SAME

The present invention relates to a three-dimensional intraoral scanner and an intraoral scanning method using same, the scanner being capable of reducing a matching error generated during a three-dimensional model data generation process for all the teeth in an oral cavity, and the three-dimensional intraoral scanner and the intraoral scanning method using same, according to one embodiment of the present invention, generate three-dimensional model data for all the teeth in an oral cavity by using a large-area scan image, thereby enabling the minimization of cumulative errors generated when the three-dimensional scan data is matched, and match, with the three-dimensional model data, three-dimensional scan data generated by using a narrow-area two-dimensional scan image, thereby enabling improved precision of the three-dimensional model data. 本发明涉及能够减少在生成关于口腔内所有牙齿的三维模型数据的过程中发生的整合误差的三维口腔扫描仪及使用其的口腔扫描方法，根据本发明的一个实施例的三维口腔扫描仪及使用其的口腔扫描方法，利用广泛区域的扫描图像生成关于口腔内所有牙齿的三维模型数据，因此能够最小化整合三维扫描数据的情况下发生的累积误差，将利用狭窄区域的二维扫描图像生成的三维扫描数据整
