Abstract

Since the technology of current image sensors is limited to the megapixel class, it is necessary to use an image-stitching technique to create a gigapixel image from hundreds or thousands of photos taken by a megapixel image sensor. In this paper, we investigate the entire process of gigapixel camera technology employing a robotic panoramic head plus a stitching technique, and analyze the gigapixel camera technologies of Duke University and BAE Systems from the viewpoint of optical design structure. Hopefully this knowledge will lead to a new optical structure for a gigapixel camera. Meanwhile, we also perceive the need for additional image processing to reduce the noise of photos with a background of fog and mist, taken far from the camera lens.

현재의 이미지 센서기술은 메가픽셀 급에 한정되어 있는데 메가픽셀 급의 이미지 센서로 기가픽셀의 이미지를 생성하기 위해서는 필수적으로 중첩영역의 이미지를 하나로 합성하는 스티칭(stitching) 기법을 쓸 수밖에 없다. 본 논문에서는 로봇파노라마헤드와 스티칭 기법을 사용하여 기가픽셀카메라 기술의 전 과정을 탐구해 보았다. 그리고 이 과정을 통해서 얻어진 경험이나 이해를 바탕으로 듀크대와 BAE의 기가픽셀카메라 기술에 대해서도 설계해석을 시도해 보았다. 또 나아가, 새로운 기가픽셀카메라의 광학구조에 대한 모색도 시도해 보았다. 기가픽셀카메라 기술에서는 스티칭 작업과는 별도로 먼거리의 피사체 혹은 대기오염과 같은 원인으로 발생하는 흐릿한 영상부분을 보정하는 것이 필수적이라는 것도 파악되었다.
