Abstract

A pan-tilt-zoom (PTZ) camera-based monitoring system for efficient monitoring in the engine room of a vessel was designed. A number of places exist where traditional analog instruments are still used in vessel engine rooms, and blind spots closely related to safety exist, for which flooding or fire is a concern. A camera-based monitoring system that guarantees a wide range at a relatively fast cycle for these monitoring points can be an effective alternative to enhance the safety of a vessel. Therefore, a multiview monitoring system is proposed in which the functions of the existing PTZ camera are further strengthened using a software. The monitoring system comprises four modules: camera control, location registration, traversal control, and multiview image reconstruction. The effectiveness of the method was evaluated through a series of experiments in an engine room environment.

본 논문은 선박 기관실 내의 효율적인 감시를 위한 팬-틸트-줌(PTZ) 카메라 기반의 모니터링 시스템의 설계 방법을 다룬다. 선박 기관실에는 여전히 전통적인 아날로그 계기들을 사용하는 곳이 많고, 침수나 화재 등 안전과 밀접하게 관련된 사각지대들이 다수 존재한다. 이러한 감시 개소들에 대하여 비교적 빠른 주기로 넓은 범위를 보장하는 카메라 기반 감시 시스템은 선박의 안전을 강화시킬 수 있는 효과적인 대안이 될 수 있다. 이에 본 연구에서는 기존 PTZ 카메라의 기능들을 소프트웨어적 방법으로 더욱 강화시킨 형태의 모니터링 시스템을 제안한다. 보다 구체적으로는 카메라제어 모듈, 위치등록 모듈, 순회제어 모듈, 멀티뷰 영상재구성 모듈로 구성된 모니터링 시스템의 설계 방법을 제안하고, 제안된 방법은 기관실 환경에서의 실험을 통해 그 효용성을 평가한다.
