SAR 위성영상 기반 선박탐지 시스템 소개 (2016년 5월, KOMPSAT-5 위성관측자료 중심으로)

open access: yes, 2016
한국해양과학기술원에서 SAR 위성영상을 입력받아 자동 기하보정 후 선박탐지 알고리즘 수행을 통해 위성에서 관측한 선박의 위치 좌표를 표출하는 ‘SAR 위성영상 기반 선박탐지 시스템’을 개발 및 시험 적용 중에 있다. 본 연구에서는 2016년 5월 제주도에서 관측된 KOMPSAT-5 위성영상을 이용하여, 선박탐지 시스템을 테스트 하고 결과에 대한 검토를 통해 개선방향을 도출하는 것을 목적으로 한다.
