Title:
THREE-DIMENSIONAL FACIAL MODEL GENERATION METHOD AND APPARATUS, DEVICE, AND MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/120810
Kind Code:
A1
Abstract:
A three-dimensional facial model generation method and apparatus, a device, and a medium, belonging to the technical field of computer vision of artificial intelligence. Said method comprises: acquiring three-dimensional face meshes of an inputted target object; aligning, according to key points of a face, the three-dimensional face meshes with a first three-dimensional facial model of a standard object; fitting partial regions of the first three-dimensional facial model with the three-dimensional face meshes, to obtain a partially-fitted second three-dimensional facial model; and fitting all regions of the second three-dimensional facial model with the three-dimensional face meshes, to obtain a globally-fitted three-dimensional facial model of the target object. By performing region-based fitting of a first three-dimensional facial model having a small number of key points with three-dimensional face meshes, to form a second three-dimensional facial model having a large number of key points, and performing fitting on the basis of the second three-dimensional facial model so that the generated three-dimensional facial model of a target object is closer to the target object.
