Embodiment Construction

[0031] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. Where the following description refers to the drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the illustrative examples below are not intended to represent all implementations consistent with this application. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present application as recited in the appended claims.

[0032] First, the terms involved in this application are explained:

[0033] Multi-modal interaction: Users can communicate with avatars through text, voice, expressions, etc. The avatars can understand user text, voice, expressions and other information, and can in turn communicate with users through text, voice, expressions, etc.

[0034] Duplex interaction: real-time, two-way interaction, the...

Abstract

The invention provides a virtual character driving method, device and equipment based on expression recognition, and relates to the fields of artificial intelligence, deep learning, machine learning, virtual reality and the like in the computer technology. According to the method, the face image of the user is obtained in real time in the conversation between the virtual character and the user, and the target classification of the current expression of the user is accurately recognized according to the face image of the user through the base model and the multi-modal alignment model for face expression recognition; and when it is determined that the target classification belongs to a preset expression classification and currently meets a response triggering condition of the target classification, determining corresponding driving data according to a response strategy corresponding to the expression classification of the user expression, and driving the virtual character to execute a corresponding response behavior according to the driving data and a three-dimensional image rendering model of the virtual character. Therefore, the virtual character can make a timely response to the expression of the user, the personification degree of the virtual character is improved, and the interaction between the virtual character and people is smoother and more intelligent.

Description

technical field [0001] The present application relates to the fields of artificial intelligence, deep learning, machine learning, and virtual reality in computer technology, and in particular, to a method, device, and device for driving a virtual character based on facial expression recognition. Background technique [0002] The traditional interaction between virtual characters and people is mainly based on voice. The interaction between virtual characters and people only stays at the voice level, and does not have the ability to understand visual information such as human expressions. Feedback, for example, during the avatar broadcast process, if the content currently broadcast by the avatar is not the information that the person who is the interaction object wants to obtain, the person will make an impatient or even angry expression. The dialogue is carried out smoothly and effectively, but the avatar does not have this ability; when the user interrupts the avatar broadca...
