Title:
ARTIFICIAL TOOTH MANUFACTURING INFORMATION GENERATION METHOD AND ARTIFICIAL TOOTH MANUFACTURING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/261724
Kind Code:
A1
Abstract:
An artificial tooth manufacturing information generation method is provided. The artificial tooth manufacturing information generation method may include the steps of: photographing a target tooth to acquire a primary image; correcting the primary image to acquire a secondary image; selecting an area including the target tooth from the secondary image to extract a tertiary image; selecting a noise area caused by reflected light from the tertiary image and then correcting the noise area, to acquire a quaternary image; and generating artificial tooth manufacturing information by using a pixel value of the target tooth included in the quaternary image.
