Data processing method and system based on virtual character

Abstract

The invention discloses a data processing method and a system based on a virtual character. The invention provides a data processing method based on a virtual character, comprising the following steps: S100, acquiring facial expression image information of a performer; S200, converting the facial expression image information into character expression data; and S300, processing the character expression data according to a data interpolation algorithm to get virtual expression data of a virtual character. The facial movements of a human face can be transferred to any virtual character chosen by users and demonstrated. The current facial expression change of a performer can be reflected in real time through the virtual character. A more vivid virtual character can be created, interest is added, and the user experience is enhanced. Moreover, when there is an identification fault, the action of the character can be stably controlled within an interval to make virtual character demonstration more vivid and natural.

Description

technical field [0001] The invention relates to the fields of image recognition and computer animation, in particular to a data processing method and system based on virtual characters. Background technique [0002] Nowadays, it is very common to play video on audio-visual communication equipment. The communication object in the video is often the real image of the user. With the continuous development of face acquisition technology and modeling technology, face acquisition technology and modeling technology are often applied In many important fields such as animation, film and television, games, etc., especially in the field of entertainment games, virtual live broadcast, and 3D animation that require human-computer interaction. The animation of virtual characters includes body animation and facial expression animation. In order to realize the realistic effect of virtual characters, pure body animation can no longer meet the needs of users. Realistic facial animation is an ...

AI Technical Summary

Problems solved by technology

[0003] To achieve the above goals, we need the facial expressions and movements of real people in the real world to control the facial expressions and movements of virtual characters in the virtual world. Although the facial movements of real faces collected in the prior art can be transferred to virtual characters However, it cannot be demonstrated on special virtual characters according to user needs, such as virtual characters such as giraffes that are quite different from human facial features

Moreover, the prior art cannot solve the problem of inaccurate recognition, wrong recognition or recognition failure caused by environmental factors such as light interference and poor network conditions, thus causing the failure to obtain emoticons normally and causing unstable control of virtual characters
