Title:
SIMPLIFIED METHOD FOR AUTOMATICALLY DETECTING LANDMARKS OF THREE-DIMENSIONAL DENTAL SCAN DATA, AND COMPUTER READABLE MEDIUM HAVING PROGRAM RECORDED THEREON FOR PERFORMING SAME BY COMPUTER
Document Type and Number:
WIPO Patent Application WO/2022/131418
Kind Code:
A1
Abstract:
A method for automatically detecting landmarks of three-dimensional dental scan data comprises the steps of: generating a two-dimensional depth image by projecting three-dimensional scan data; detecting two-dimensional landmarks in the two-dimensional depth image by using a fully-connected convolutional neural network model; and detecting three-dimensional landmarks of the three-dimensional scan data by back-projecting the two-dimensional landmarks onto the three-dimensional scan data.
