Abstract

The developing unmanned underwater equipment can be used for underwater construction site such as underwater leveling works. If a optical camera is applied to the unmanned underwater equipment, recognition in underwater can be gone to low due to high turbidity in working field. To overcome this problem, a sonar will be installed to the unmanned underwater equipment. In this study, the resolution of the sonar and the quality test of the sonar image under high turbidity environment were conducted. And the method to indicate the boundary of the underwater construction site was proposed. By these results, the basic performance of the sonar was evaluated.

수중사석고르기와 같은 수중공사작업을 수행하기 위하여 개발 진행 중인 무인수중장비를 수중공사현장에 투입할 경우, 작업 시 발행하는 부유물들로 인하여 탁도가 높아진다. 이러한 수중환경에서 광학카메라를 이용할 경우, 수중전방인식이 불가능할 수 있다. 이를 극복하기 위하여 무인수중장비에 소나를 탑재하고자 한다. 소나를 무인수중 장비에 적용하기에 앞서, 본 연구에서는 소나의 분해능, 탁도가 높은 물 속에서 스캐닝한 소나이미지를 확인하여 장비의 성능을 분석하였다. 그리고 수중공사현장의 경계면을 표시하기 위한 방법을 제안하였다. 이를 통하여 무인수중 장비에 적용하기 위한 소나의 기초 성능을 확인하였다.
