Patent ID: 11830196

Abstract:
In one aspect, the present application provides a method for verifying a segmentation result of a 3D digital model of jaw, the method comprises: obtaining a reference position segmentation result of a 3D digital model of jaw, where the reference position result is obtained by segmenting the 3D digital model of jaw positioned at a reference position using a first segmentation method; perturbating the 3D digital model of jaw positioned at the reference position multiple times, and segmenting the 3D digital model of jaw positioned at the multiple perturbed positions using the first segmentation method, to obtain corresponding multiple perturbed position segmentation results; and determining whether the reference position segmentation result is reliable based on similarities between the reference position segmentation result and the multiple perturbed position segmentation results, where segmentation of the 3D digital model of jaw is to segment teeth from each other and from gingiva, and is to classify facets of the 3D digital model of jaw into tooth numbers and gingiva.
