메타버스 상에서 가상 콘서트가 펼쳐지고 영화와 방송에서는 디지털 휴먼과 대형 LED wall을 이용한 가상 스튜디오 기술이 활용되는 등 가상현실에 대한 관심이 지속적으로 증가되고 있다. 이에 실제 세상을 가상 현실과 접목하기 위한 다양한 기술 개발이 활발히 진행하고 있다. 본고에서는 현실 공간에서 펼쳐지는 스포츠 및 문화공연 이벤트 등을 가상 공간에서 재현하기 위한 멀티카메라 기반 3차원 아바타 생성 기술과 센서 기술과 시각지능 기술을 활용한 모션 캡처 기술 그리고 이러한 영상 기술 어플리케이션의 토대가 되는 멀티카메라 정밀 보정 및 동기 전송 기술에 대하여 알아본다.
