The present invention relates to a safe ship docking system using camera images and a method thereof, which use difference image information obtained in real time through cameras installed in a fixed harbor or fixed ships to measure a location of and a distance from a moving ship, generate alerts by steps according to approaching distances of moving ships, and after determining the size of ships through the difference image information obtained through the cameras, differently apply a distance for generating object approaching danger alarms depending on the size of ships. According to the present invention, the system can be operated without sharing of location information between moving ships and fixed ships or fixed harbors, such that there is no worry about disconnection of communication. Since the system uses difference image information obtained through cameras to measure whether a ship moves and how much the ship approaches, the configuration of the system can be simple. The system comprises: cameras; an image receiving unit; an object sensing unit which senses ships through a difference image, morphology, and expansion calculation; a difference image storage unit; an image dividing unit which divides a sea image at a predetermined interval from top to bottom; an angle storage unit; a distance storage unit which uses angles for each sea level location stored in the angle storage unit to calculate distances to each location of sea levels; and an alarm generating unit which compares information stored in the difference image unit with information stored in the distance storage unit, and when a ship is determined to move to a fixed harbor or fixed ships, generates an alarm.

    본 발명은 고정 항만 또는 고정 선박에 설치되는 카메라를 통해 실시간으로 획득되는 차영상 정보를 이용하여 이동 선박의 위치 및 이동 선박까지의 거리를 측정할 수 있으며, 이동 선박의 접근 거리에 따라 단계별 경보를 발생시킬 뿐만 아니라, 카메라를 통해 파악되는 차영상 정보를 가지고 선박의 크기를 판단 후 선박의 크기에 따라 물체근접 위험경보를 발생시키는 거리를 다르게 적용할 수 있는 카메라 영상을 이용한 선박의 안전접안 시스템 및 그 방법에 관한 것이다. 본 발명에 따르면 고정 항만 또는 고정 선박과 이동 선박 간에 위치 정보를 서로 공유하지 않고도 운영이 가능하여 통신 두절의 문제를 걱정할 필요가 없으며 카메라를 통해 획득되는 차영상 정보를 이용하여 선박의 이동 여부 및 접근 거리를 측정할 수 있기 때문에 시스템을 간단하게 구성할 수 있다.
