Abstract

Recently panoramic image overcomes camera limited viewing angle and offers wide viewing angle by stitching plenty of images. In this paper, we propose pre-processing and post-processing algorithm which makes speed and accuracy improvements when making panoramic images. In pre-processing, we can get camera sensor information and use three-dimensional rotation angle to find RoI(Region of Interest) image. Finding RoI images can reduce time when extracting feature point. In post-processing, we propose weighted minimal error boundary cut blending algorithm to improve accuracy. This paper explains our algorithm and shows experimental results comparing with existing algorithms.

최근 카메라의 제한된 시야각을 극복하고 여러 영상을 하나의 영상으로 정합하여 넓은 시야각을 제공하는 파노라마 영상 기술 개발에 대한 연구가 활발히 진행되고 있다. 본 논문은 파노라마 영상 제작 시 속도와 정확도 향상을 위한 전처리, 후처리 과정을 제안한다. 전처리 단계에서 카메라 센서 정보인 3차원 회전각으로 영상 간 공통 영역을 구하여 스티칭 알고리즘 소요 시간을 단축한다. 또한 후처리 단계에서 가중치를 추가한 최소 오차 경계 블랜딩 방법을 제안하여 파노라마 영상의 정확도를 향상시키고 이를 실험을 통해 결과 검증 및 비교한다
