Abstract

본 논문은 파노라마 모자익의 접합 질을 판단하기 위해 접합 신뢰도라는 수량적 기준을 제시한다. 또한, 파노라마의 자동 생성과 따른 시각화를 위해 필요한 초점거리 측정에 접합 신뢰도가 유용함을 보인다. 이미지로부터 초점거리를 복원하는 기존 방법은 일반적인 파노라마 모자익에서 나타나는 잘못 접합된 부분을 초점거리 계산에 포함하기 때문에 부정확하다는 단점이 있다. 제안 방법은 높은 접합 신뢰도를 가진 일정 개수의 이미지를 선별할 수 있기 때문에 초점거리를 따르고 정확하게 자동 측정한다. 접합의 신뢰도를 계산하기 위해, 제안 방법은 카메라 회전 움직임 제약조건의 만족 여부를 판단할 수 있는 특징점을 정의하고, 이 특징점의 이상적인 위치와 실제 위치의 차이를 계산한다. 본 논문에서 제시한 제약조건은 카메라의 자유 회전 움직임에서 항상 만족하고, 이는 수학적으로 증명된다. 마지막으로, 실험을 통해 제안 방법이 기존 방법보다 초점거리의 편차가 작다는 것을 보이고, 파노라마 모자익의 접합 질을 높인다는 것을 보인다.
