Problems solved by technology

However, there is no robot on the market that can automatically make facial expressions and gestures through voice drive when speaking in virtual reality.
Therefore, when the virtual character wants to speak, professionals are required to make images of the virtual reality character, which is not only costly, but also time-consuming and labor-intensive.

Abstract

The invention discloses a method of driving an expression and a gesture of a character model in real time based on voice for driving the expression and the gesture of a speaking virtual reality character model. The method comprises steps: voice data are acquired; the weight values of basic animations are calculated; the weight values of decorative animations are calculated; the weight values of basic mouth shape animations are calculated; a synthesized animation is modified; and a facial expression grid is outputted. Through driving the facial expression and the mouth expression of the current virtual reality character by sound wave information of the voice, the virtual image can automatically generate an expression as natural as a real person, no virtual reality character images need to be made, the cost is low, and time and labor are saved.

Description

technical field [0001] The present invention relates to virtual reality (VR, virtual reality), in particular to a method for generating expressions and gestures of a character model in VR. Background technique [0002] With the development of virtual reality technology, virtual reality devices and matching virtual reality engines have appeared on the market. In the human-computer interaction of virtual reality, the reality of virtual characters will greatly affect the user's experience. Compared with real characters, in order to solve the worries of users, some companies have developed intelligent robots, which can automatically recognize user intentions and answer them. For example, Microsoft’s robot Xiaoice has realized automatic dialogue and communication with users in text. function. Moreover, the robot's text reply can also be converted into a voice stream and corresponding emotional data through TTS' text-to-speech technology. But there is no robot on the market tha...
