THREE-DIMENSIONAL INTRAORAL SCANNER AND INTRAORAL SCANNING METHOD USING SAME

摘要

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.
