Abstract

To support anti-collision between ship to ship and sea-search and sea-rescue work, ship automatic identification system(AIS) that can both send and receive messages between ship and VTS Traffic control have been adopted. And port control system can control traffic vessel service which is co-operated with AIS. For more efficient traffic vessel service, ship recognition and display system is required to cooperated with AIS. In this paper, we propose ship detection system which is co-operated with AIS by using background estimation based on image processing for on the sea or harbor image extracted from camera. We experiment with on the sea or harbor image extracted from real-time input image from camera. By computer simulation and real world test, the proposed system show more effective to ship monitoring.

선박과 선박, 선박과 육상 관제소간에 선박의 위치정보 등을 자동 송수신하여 선박 간의 충돌 방지 및 해난 수색 구조 활동을 지원하기 위하여 선박 자동 식별 장치인 AIS(automatic identification system)을 채용하고 있다. 그리고, 항만의 관제시스템은 선박 AIS와 연계하여 선박의 통항을 관리한다. 효율적인 통항관리를 할 수 있도록 AIS 연동하는 선박 인식 및 표출 시스템이 요구되고 있다. 본 논문에서는 카메라로부터 입력된 해상 또는 항만 영상에 대하여 배경추정을 이용한 영상기반의 선박검출과 검출된 해당 선박의 AIS 신호를 연동하여 모니터 상에 표출하는 AIS 연동 선박검출 방법을 제안한다. 해상 또는 항만에서 실시간 입력되는 영상에 대하여 선박 검출 실험을 하였다. 시뮬레이션 및 실험결과 제안하는 알고리즘이 항만의 선박 관제에 효과적으로 활용할 수 있음을 확인하였다.
