The existing ship repair tool management system based on hand writing has many problems such as frequent loss of tool and overdue. To solve this problem, same systems have adopted the bar-code system. However, the systems can't cope with a problem to substitute spurious tool for genuine one on bar-code damage. Therefore, additional validation steps are necessary in order to manage expensive ship repair tool. In this paper, we propose an image comparison method for ship repair tool management. To be more concrete, we propose a normalization method and determination conditions for image comparison to use characteristics of mobile device. The normalization method makes use of the characteristics of mobile device that provides functions of real time recording, overlapping and cropping images. The proposed method applies three conditions(sum of inner angles, size of angle, position of corner coordinates) into the comparison module. The implemented system shows good performance on change direction, lighting, size and etc. The accuracy is more than 95%.

부산항 내의 3대 주요 항만인 감천항에는 일반화물선으로부터 어선, 수리를 위해 기항하는 선박 등 다양한 선종과 상태의 선박이 감천항 방파제와 두도(頭島) 부근의 좁은 수역을 통과하여 입출항하고 있는데, 장비가 불량하거나 선체 구조물 또는 기타의 이유로 운항자의 시야를 제한하는 선박들이 방파제와 두도 부근에서 조우할 경우 충돌, 좌초 등의 해양사고 발생 가능성이 증가하게 된다. 본 연구를 통하여 감천항을 기항하는 항해장비불량선박 및 시야 제한 선박의 실례에 대하여 설명하고, 해당 선박의 안전도선을 위한 방안을 모색하고, 후속연구의 필요성을 강조하고자 한다.

Most small and petty marine engine mechanical shops are jumbled up and their facilities are falling behind, and is varying. By theses reasons, it's capacity becomes weak and also by the insufficience of the promotion policy, it is hard to be expected to improve their business. The feature, management, manpower, facilities for the marine engine mechanical shops were researched and their problems were analyzed. In this study, the way to strengthen their capacity and to manage the shops efficiently was researched.
