레이저 스캔 측정방식 중 위상차방식의 장점은 무엇인가? | 위상차방식은 60m 이내의 단거리 측정에 사용되며 발신 레이저와 수신 레이저의 위상차를 해석하여 측정하는 방식이다. 유효측정거리는 짧지만 데이터 취득 속도는 최대 625,000 pixel/sec의 빠른 속도로 밀도가 높고 복잡한 대상물의 측량에서 높은 해상도로 스캐닝 할 수 있는 장점이 있다. 펄스방식은 레이저가 발신되어 수신기에 도달하는 시간을 측정하는 방식으로 토탈 스테이션에 주로 사용되는 방법이 다. | |
레이저 스캔 기술이란 무엇인가? | 레이저 스캔 기술은 LIDAR(Light Detection and Ranging) 또는 LADAR(Laser Detection and Ranging)이라 일컬어지는 측정 기술로 레이저 스캐너가 스캔 대상물의 3차원 형상 정보를 디지털화하여 데이터를 취득하는 기술이다(Kim et al., 2013). | |
3D laser scanning 기술은 어떤 분야에 적용되고 있는가? | 앞서 얘기한 화재피해 건축 구조물의 인력 중심 안전 진단·평가 방식이 가진 근본적인 한계를 극복하기 위해서 ICT(Information and Communication Technology)기술의 적용이 늘어나고 있다. 3D laser scanning 기술은 교량 및 빌딩 보수, 시공 진도 모니터링, 문화재 보존, 건설 자재 형상 및 품질관리, 유지관리 등 다양한 분야에 적용되고 있다(Kim et al., 2013). |
