Abstract

The performance of the existing tunnel scanning system was analyzed through the post-evaluation of NETIS (New Technology Information System) and Inspection Support Technology Performance Catalog. Suggestions for improvement and development direction of the tunnel scanning system were deduced. As new technology of Japan gave priority to providing user-centered information, it was possible to objectively compare and analyze the characteristics of various tunnel scan systems through post-evaluation of NETIS and standard test methods in the Inspection Support Technology Performance Catalog. Construction New Technology of Korea was centered on suppliers of technology certification, making it impossible to objectively compare the performance of tunnel scanning systems. The performance was compared and evaluated indirectly by comparing the specifications of the camera, which is a core device of Japan's tunnel scanning system. For the future development of tunnel scanning systems, high-resolution and fast exposure performance of cameras and corresponding high-intensity lighting devices are required. For this purpose, it is necessary to make an experimental environment in which the performance of the camera and lighting can be analyzed indoors.

본 논문은 일본의 성능평가 제도인 NETIS의 사후평가와 점검 지원 기술 성능 카탈로그를 통해 기존 터널 스캐닝 시스템의 성능을 분석하였다. 분석을 통해 터널 스캐닝 시스템의 개선 사항과 개발 방향에 대한 시사점을 도출하였다. 일본의 신기술은 사용자 중심의 정보 제공을 우선시하여 NETIS의 사후평가와 점검 지원 기술 성능 카탈로그의 표준시험방법을 통해 다양한 터널 스캐닝 시스템의 특성을 객관적으로 비교하고 분석할 수 있다. 국내의 건설신기술은 기술인증의 공급자 중심으로 터널 스캐닝 시스템에 대한 객관적인 성능 비교는 불가능하였다. 일본의 터널 스캐닝 시스템의 핵심장치인 카메라의 제원을 비교하여 성능을 간접적으로 비교 평가하였다. 향후 터널 스캐닝 시스템 개발을 위해서는 카메라의 고해상도와 빠른 노출 성능 그리고 이에 부합되는 고휘도의 조명 장치가 요구된다. 실내에서 카메라와 조명의 성능을 분석할 수 있는 실험 환경 조성도 필요할 것으로 판단된다.
