본 논문에서는 야간 및 해무 상태에서 선박의 안전 운항을 지원할 수 있는 해상 적외선 스테레오비전 대구경 감시 시스템용 거리 측정 기법을 제안하였다. 선박의 안전 운항을 위한 감시 시스템에는 스테레오비전 정보를 이용하여 거리를 측정하는 알고리즘이 필요하며 물체의 이미지 및 물체까지의 거리정보를 디스플레이 하는 기능을 구현하였다. 원거리 측정 및 야간 측정 기능을 구현하기 위해 적외선 스테레오비전 및 대구경 렌즈를 이용하였으며, 해상에서 파고에 의한 흔들림으로 이미지의 연속적인 처리가 어려운 측면이 있어 물체의 비전 정보를 이용하여 거리를 계산하는 알고리즘 및 계산된 거리 정보를 디스플레이하는 프로그램을 개발하였다. 이러한 실험 결과가 선박 안전운항을 위한 유용한 시스템이 될 것으로 예상하고 있다.
