Title:
LOCAL COORDINATE SYSTEM SETTING METHOD FOR THREE-DIMENSIONAL DIGITAL MODEL OF TEETH
Document Type and Number:
WIPO Patent Application WO/2019/214339
Kind Code:
A1
Abstract:
A local coordinate system setting method for a three-dimensional digital model of teeth. The method is executed by a computer and comprises: obtaining a first three-dimensional digital model, which is a three-dimensional digital model for representing first teeth on the basis of a world coordinate system; and setting a local coordinate system for the three-dimensional digital model by using a first artificial neural network on the basis of the first three-dimensional digital model, the first artificial neural network being a trained artificial neural network having a deep learning ability.
