Document Type and Number:
WIPO Patent Application WO/2022/014951
Kind Code:
A1
Abstract:
The present invention relates to: a scanner having a plurality of scan units of which the relative positions on a coordinate system are fixed; and a scan data generation method using such scanner to enable easy and precise matching of scan data obtained from each of the plurality of scan units. By using the scanner according to the present invention, not only intraoral scan data but also facial scan data may be obtained, and the obtained intraoral scan data and facial scan data may be easily and precisely matched. In addition, the present invention relates to: a calibration plate for setting and calibrating the fixed relative positions of the scanner which has the plurality of scan units of which the relative positions on the coordinate system are fixed; and a calibration method using same.
