Facial expression reconstruction method and device based on big data

Abstract

The invention provides a facial expression reconstruction method and device based on big data, and the method comprises the steps: obtaining a facial expression image sequence of a first user, wherein the face of the first user has a plurality of feature points, and the facial expression image sequence comprises a plurality of different facial expression image frames; determining the movement track of each feature point according to the changes of coordinates of each feature point in the plurality of different facial expression image frames; and reconstructing the facial expression on a three-dimensional facial geometric model of a second user according to the movement tracks of all feature points. According to the embodiment of the invention, the method obtains the change information of the facial expression of the first user in a mode of setting the feature points on the face, determines the movement track of each feature point according to the changes of the coordinates of each feature point, carries out the reconstruction of the facial expression according to the movement tracks of all feature points, solves a problem that an application scene of the facial expression reconstruction technology is limited, and reduces the professional and manufacturing cost of the facial expression capturing, recognition and reconstruction processes.

Description

technical field [0001] The present invention relates to the technical field of facial expression capture, recognition and reconstruction, in particular, to a facial expression reconstruction method and device based on big data. Background technique [0002] At present, applications based on facial expressions are becoming more and more important, ranging from simple network virtual role guides and remote virtual communication to complex automatic face recognition and automatic query of face image databases, etc., all involve changes in facial expressions. The research on facial expression recognition and reconstruction has very important significance and very broad application prospects. Facial expression recognition and reconstruction not only help to develop an anthropomorphic multimedia computer system, but also help to further improve the computer's processing of specific video signals. Ability, especially in video understanding, computers can use facial expression infor...
