초록

스캐닝소나 시스템은 수중의 인공구조물을 2차원 이미지와 3차원 데이터로 나타낼 수 있는 음향센서로 탁한 시계환경에서 카메라를 대신하여 시각화 할 수 있는 센서이다. 특히 스캐닝소나 시스템은 물체의 길이, 면적, 부피를 측정할 수 있어 수중구조물의 위치, 크기, 상태를 점검하는데 필수적인 센서이다. 선진국에서는 스캐닝 소나를 이용하여 해저면, 교각하부, 파워플랜트의 취수관등 수중의 구조물 안전성 평가에서 다양하게 활용되고 있다. 본 논문에서는 국내에서 실시한 2차원 이미지 취득과 취득된 이미지의 모자이킹 결과를 소개하고, 3차원 데이터 취득과 합성 결과를 설명한다. 연구를 통해 향후 국내 연안의 인공구조물 안전성 평가에 유용하게 활용될 수 있음을 확인하였다.

Abstract

The scanning sonar system is an acoustic sensor that can show a two-dimensional image and three-dimensional data of a man-made structure in the water, and can visualize it in place of a camera in a low visibility environment. The scanning sonar system is essential to verify the position, size and condition of the underwater structure because it is able to measure the length, area and volume of the object. In the country advanced in the marine, scanning sonar is used variously in the evaluation for the structure safety in water such as seabed, pier, power plant, etc. In this paper, we introduce two-dimensional images and its results of mosaic and three-dimensional data and its synthesized results as well acquired in our sea. Through this study, it was confirmed that it could be useful for the safety assessment of artificial structures in our marine environment in the future.
