Abstract

The final purpose of this study is to find a method of projecting the characteristics and attractiveness of actual actor's facial expressions onto avatars based on facial capture technology to improve facial expressions of digital actors. Metaverse performances can create various situations without time and space constraints, providing new cultural experiences to the audience watching them. However, it is also true that in current metaverse performances, digital actors' facial expressions are partially vulnerable to conveying emotions. It also acts as one of the factors that interfere with the audience's immersion. One of the problems is that not all avatars have unique characteristics outwardly, so the lack of differentiation is also one of the problems. To overcome these limitations, we propose a method of modeling the actual actor's facial expressions with 3D scans to create a morph target and applying it to avatars using facial capture technology.

본 연구는 디지털 액터의 표정연기 개선을 위해 페이셜 캡처 기술을 기반으로 실제 배우 표정의 특징과 매력을 아바타에 투영하는 방법을 모색하는 것에 최종 목적을 둔다. 메타버스 공연은 시공간의 제약 없이 다양하게 상황을 연출 할 수 있어 이를 관람하는 관객에게 새로운 문화적 경험을 제공한다. 하지만 현재 메타버스 공연에서 디지털액터의 표정연기는 감정을 전달하는 것에 일정 부분 취약한 것도 사실이다. 또한 이는 관객의 몰입을 방해하는 요인중 하나로 작용한다. 모든 아바타가 외형적으로 고유한 특징을 지니지 못하여 차별성이 부족한 부분도 문제점 중 하나이다. 이러한 한계점을 극복하기 위하여 실제 배우의 표정을 3D 스캔으로 모델링하여 모프타겟을 제작하고, 페이셜캡처 기술을 활용하여 아바타에 적용하는 방법을 제안한다.
