Title:
METHOD FOR AUTOMATICALLY SEGMENTING TEETH IN THREE-DIMENSIONAL SCAN DATA, AND COMPUTER-READABLE RECORDING MEDIUM HAVING RECORDED THEREON PROGRAM FOR EXECUTING SAME ON COMPUTER
Document Type and Number:
WIPO Patent Application WO/2023/128046
Kind Code:
A1
Abstract:
A method for automatically segmenting teeth in three-dimensional scan data comprises the steps of: converting three-dimensional scan data into a two-dimensional image; determining three-dimensional landmarks using a first artificial intelligence neural network that receives the two-dimensional image as an input; generating cutting data by cutting the scan data using the three-dimensional landmarks; determining anchor points using the three-dimensional landmarks and the cutting data; generating mapping data by mapping the cutting data to predetermined spaces using the anchor points; determining a segmentation mask using a second artificial intelligence neural network that receives the mapping data as an input; and mapping the segmentation mask to the scan data or the cutting data.
