Abstract

Realistic videos using multi-view videos are created so that the contents shown on multi-view displays or screens look realistic. These images have been mostly used for special videos for exhibition, but, recently, systems such as Screen X have given rise to multi-view images as a format for storytelling contents such as movies. This study used HD-level broadcasting digital video camera with three zoom lenses for shooting wide to close-up shots focusing on a person, in the same way as Screen X, and identified and analyzed problems found during multi-view image registration correction. The results of this study suggested, provided the shooting technique and equipment are improved, the multi-view format can be used for conveying stories and information. Future research will need to investigate and supplement relevant techniques that will enable production of high-quality multi-view image contents by using a cinema-grade camera with standard lenses, instead of using broadcasting-grade zoom lenses.

다면영상을 이용한 실감영상은 스크린이나 다면으로 구성된 디스플레이에서 펼쳐지는 내용이 사실적으로 보여지게 제작되어지고 있다. 이러한 다면영상은 전시를 위한 기획영상에서 주로 사용되었으나 Screen X와 같은 시스템을 통해 영화와 같은 스토리를 전달할 수 있는 포맷으로 재조명 되고 있다. 이번 연구는 3대의 줌렌즈가 장착된 HD급 방송용 디지털 비디오를 이용해 Screen X와 같은 방법으로 인물을 중심으로 한 전경 장면부터 클로즈업 장면까지 촬영한 후 다면 영상 정합보정을 통해 발생되는 문제점을 분석 파악하였다. 촬영 방법과 장비를 보완하면 다면영상이란 포맷이 스토리와 정보 전달이 가능한 매체임을 제시하였고 향후 방송용 줌렌즈를 이용한 촬영보다 표준렌즈 기반의 시네마급 카메라를 이용한 양질의 다면영상 콘텐츠를 제작할 수 있도록 기술적 연구와 보완이 필요하다.
