Face recognition system and method for expression capture

Abstract

The invention discloses a face recognition system and method for facial expression capture. The face recognition system comprises a face image acquisition system and a face feature recognition module;the real three-dimensional face reconstruction system is used for establishing a three-dimensional face model according to the structured light imaging principle of the face image acquisition system,and re-determining a three-dimensional coordinate system of the three-dimensional face model; the virtual character three-dimensional model system is used for establishing a three-dimensional virtualcontour in the same three-dimensional coordinate system and filling a virtual feature part in the three-dimensional virtual contour; the posture matching module is used for selecting a plurality of active selection feature points of each facial feature part and determining a proportional relation; the feature point association module is used for determining passively selected feature points according to the proportional relation; and the expression dynamic tracking module determines three-dimensional coordinate changes of passive selection feature points of the virtual feature part in a three-dimensional coordinate system according to a proportional relation. According to the invention, the similarity between the face features of the real face and the face features of the virtual character is ensured through the face recognition technology.

Description

technical field [0001] The invention relates to the technical field of face recognition, in particular to a face recognition system and method for expression capture. Background technique [0002] Face recognition is a biometric technology for identification based on human facial feature information. A camera or camera is used to collect images or video streams containing human faces, and automatically detect and track human faces in the images, and then detect the detected A series of related technologies for face recognition. The face recognition system mainly includes four components: face image acquisition and detection, face image preprocessing, face image feature extraction, and matching and recognition. [0003] At present, face recognition is not only used for identification. At present, face recognition technology is widely used in daily entertainment life, such as camera shooting, picture comparison, etc. Combine face recognition technology with expression capture...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a face recognition system and method for expression capture, to solve the problem that the traditional face recognition technology in the prior art is used to identify facial contours and facial features, which cannot realize expression capture, and then cannot create a facial expression similar to facial features.
