DEVICE AND METHOD FOR MATCHING THREE-DIMENSIONAL INTRA-ORAL SCAN DATA USING COMPUTED TOMOGRAPHY IMAGE

Document Type and Number:

WIPO Patent Application WO/2022/158804

Kind Code:

A1

Abstract:

Disclosed is a device for matching three-dimensional intra-oral scan data, the device comprising a computed tomography (CT) image depth map generation unit, a depth map coordinate difference information determination unit, a depth map correction unit, and an intra-oral scan model recovery unit. The CT image depth map generation unit generates a depth map of a CT frame from a CT image by using information about a single scan frame of the scan data. The depth map coordinate difference information determination unit determines depth map coordinate difference information between the depth map of the CT frame and a depth map of the scan frame. The depth map correction unit corrects the depth map of the scan frame on the basis of the depth map coordinate difference information. The intra-oral scan model recovery unit recovers a three-dimensional intra-oral scan model on the basis of the corrected depth map of the scan frame.
