Title:
METHOD AND DEVICE FOR MATCHING THREE-DIMENSIONAL ORAL SCAN DATA VIA DEEP-LEARNING BASED 3D FEATURE DETECTION
Document Type and Number:
WIPO Patent Application WO/2022/154523
Kind Code:
A1
Abstract:
Disclosed is a three-dimensional oral scan data matching device including a matching unit, a deep-learning unit, a scanned frame feature determination unit, and a scan data re-matching unit. The matching unit matches a plurality of scanned frames to generate a full mouth image. The deep-learning unit performs deep-learning to detect a feature of the full mouth image. The scanned frame feature determination unit determines a feature of the plurality of scanned frames by utilizing the feature of the full mouth image. The scan data re-matching unit re-matches the plurality of scanned frames on the basis of the feature of the plurality of scanned frames, to reconstruct a three-dimensional oral model.
