Abstract

In this paper, we propose an efficient algorithm for constructing cylindrical panoramic image. At first, we describe a fast image alignment algorithm, which matches image strips located on equal distance for image centers. And then, we explain how to estimate accurately the effective focal length of camera by a bisection method. Although there is a limitation in that the image should be taken by a camera with pure panning motion, the proposed simple and fast algorithm is applicable to practical application.

본 논문에서는 실린더 파노라믹 영상을 생성하기 위한 효율적인 알고리즘을 제시한다. 먼저 영상 정렬 시 실린더와 영상간의 관계를 이용한 영상의 중심으로부터 같은 거리에 있는 영상 스트립을 비교하는 효율적인 영상 정렬 알고리즘을 기술하고, 원과 원에 접하는 다각형간의 관계를 이용하여 이분법으로부터 초점거리를 정확하게 추정하는 방법을 설명한다. 본논문에서 제안하는 알고리즘은 카메라 운동에 대한 제약점은 있지만, 빠르고 간단하기 때문에 실제 응용에서 효과적으로 사용 가능하다.
