Abstract

The invention discloses a virtual figure expression driving method and system. The method includes following steps: acquiring color information and depth information of human facial expressions; synthesizing the depth and color information of the human facial expressions, and extracting key information nodes; analyzing and comparing the key information nodes with a previously learned human facialexpression template to digitalize a practical human facial expression as a weight value, and transmitting the weight value to a middleware; performing standardization processing on the weight value bythe middleware, performing optimization processing to reduce transmission time-delay of data, and outputting the data to a corresponding engine port; and driving virtual figure expressions to changethrough the processed weight data. According to the technical scheme of the method, compared with pure video recording and post-rendering of a conventional three-dimensional production tool, virtual figures can be driven in real time, and technical support is provided for live-broadcasting programs or real-time interaction performance etc.

Description

technical field

[0001] The technical field of virtual animation display of the present invention specifically relates to a virtual character expression driving method and system, which is a technology for real-time reflection of character facial expressions, demeanor, emotions, and atmosphere in virtual content, and is applied to expression production in all virtual content . Background technique

[0002] With the maturity of technology in the field of virtual content production and the gradual acceptance of virtual content carriers in the market, the market urgently needs efficient and low-cost animation / expression production methods in the field of content production. The efficiency of traditional animators using traditional manual methods to produce expression animations can no longer meet the content production efficiency needs of the existing non-film industries; at the same time, the demand for real-time interaction in tourism, radio and television, games, and virtual ...
