Abstract

The embodiment of the invention discloses a method and device for determining lip actions of a virtual image. The method for determining the lip action of the virtual image comprises the following steps: acquiring a target audio; cutting the target audio into a target audio clip sequence; respectively inputting each section of target audio clip in the target audio clip sequence into a lip action coefficient model to obtain a lip action coefficient sequence corresponding to a time sequence; and based on the lip action coefficient sequence, driving the target virtual character to make lip actions corresponding to the target audio clips in the target audio clip sequence. According to the method, the lip action coefficient corresponding to the lip action of the virtual image is directly generated from the audio, and then the lip action of the virtual image is generated based on the lip action coefficient, so that the real-time performance in user interaction can be met. And meanwhile, thelip action coefficient is not an image, and is not limited to a specific virtual image, so that the requirements of different application scenes can be met.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to the field of computer network technology, and in particular to a method and device for determining lip movements of virtual images. Background technique [0002] Most of the avatars in the current industry use manual adjustments by animators or complex facial motion capture equipment to realize the corresponding relationship between the avatar's mouth movements and audio. [0003] However, artificially adjusting the mouth movement of the avatar to correspond to the audio through manual drawing or motion capture equipment requires more manual fine-tuning and cannot achieve real-time interaction with the user. Contents of the invention [0004] The embodiments of the present application provide a method and an apparatus for determining lip movements of an avatar. [0005] In the first aspect, the embodiment of the present application provides a method for determining...
