Document Type and Number:
WIPO Patent Application WO/2023/185395
Kind Code:
A1
Abstract:
The present disclosure provides a facial expression capturing method and apparatus, a computer device, and a storage medium. The method comprises: acquiring face driving image data; performing first feature extraction on the face driving image data to obtain a first expression feature of the face driving image data; generating a virtual face image on the basis of the first expression feature, and performing second feature extraction on the virtual face image to obtain a second expression feature of the virtual face image; and generating a blend shape (BS) coefficient on the basis of the second expression feature, the BS coefficient being used for inputting a three-dimensional game engine to generate a three-dimensional virtual face model. According to embodiments of the present disclosure, the BS coefficient can be automatically obtained on the basis of the face driving image data, such that a 3D virtual role model can be quickly driven on the basis of the automatically obtained BS coefficient.
