Abstract

This paper analyzes case studies of using 3D LiDAR technology for structural health monitoring and evaluates its utility and limitations. LiDAR technology is shown to be an efficient, non-contact tool that accurately measures structural deformation and damage, as demonstrated in case studies such as the Pohang-Yeongdeok Highway and Nungan Overpass. However, the analysis also highlights limitations, including the time-consuming manual data analysis process and the high cost of LiDAR systems. Additionally, LiDAR struggles to detect internal damage or material changes. To address these issues, the development of AI-based automated software is suggested, which could expedite data processing. Further advancements are expected in combining LiDAR with other sensor technologies for more comprehensive structural analysis, as well as in reducing equipment costs and increasing portability to expand its commercial use.

본 연구에서는 3차원 라이다(LiDAR) 기술을 활용한 구조물 안정성 평가 사례를 분석하고, 라이다 기술의 유용성과 한계점을 논의하는 것을 목표로 한다. 먼저, 라이다 기술이 구조물의 변형 및 손상을 정밀하게 측정할 수 있는 비접촉식 계측 도구로서 효율성을 입증하였으며, 이를 통해 구조물의 상태를 신속히 평가할 수 있음을 포항-영덕 고속도로 및 영동선 능안육교 사례에서 확인하였다. 하지만, 라이다 데이터를 수작업으로 분석하는 데 시간이 많이 소요되고, 비용이 높다는 한계가 있었다. 또한, 내부 손상이나 재료 특성까지 감지하는 데 한계가 있다는 점도 지적되었다. 이러한 한계를 극복하기 위해 AI 기반의 자동화 소프트웨어 개발이 필요하며, 라이다 기술의 상용화를 위해서는 장비 소형화 및 비용 절감이 요구된다. 향후 발전 방향으로는 다른 센서와의 결합을 통해 보다 종합적인 구조물 분석이 가능할 것으로 기대된다.
