Abstract

The embodiment of the invention discloses a method and device for controlling the mouth shape change of a three-dimensional virtual portrait, and relates to the field of cloud computing. A specific embodiment of the method comprises the steps of obtaining a to-be-played voice; sliding a preset time window in the to-be-played voice according to a preset step length to obtain at least one voice segment; generating a mouth shape control parameter sequence for the to-be-played voice based on the at least one voice segment; and controlling the mouth shape of a preset three-dimensional virtual portrait to change based on the mouth shape control parameter sequence in response to playing of the to-be-played voice. According to the embodiment, the mouth shape control parameter sequence is automatically generated based on the to-be-played voice, so that the voice and the three-dimensional virtual portrait with the synchronously changed mouth shape are efficiently rendered.

Description

technical field [0001] The embodiments of the present disclosure relate to the field of computer technology, and in particular to a method and a device for controlling lip-shape changes of a three-dimensional virtual portrait. Background technique [0002] 3D virtual portrait speech lip synchronization has always been a research hotspot, and has a wide range of applications. Common application fields include film and television animation, game entertainment and so on. Traditional 3D virtual portrait voice lip synchronization technology usually requires professional technicians to manually set the key frames of the 3D virtual portrait according to the given voice clips, and adjust the mouth shape for the 3D virtual portrait in these key frames. The mouth shape of the three-dimensional virtual portrait in the transition frame between the key frames is automatically generated by the animation engine. For example, it can be automatically generated by animation engines such as ...
