Since cracks in concrete structures expedite corrosion of reinforced concrete over a long
period of time, regular on-site inspections are essential to ensure structural usability and …

In this study, we propose an improvement method that can create U-Net model which detect
fine concrete cracks by applying a weighted loss function. Because cracks in concrete are a …

본 연구에서는 가중치 오차 함수를 적용하여, 미세한 콘크리트 균열을 감지하는 U-Net 모델을
만들 수 있도록 개선 방안을 제안한다. 콘크리트 균열은 안전을 위협하는 요소이기 때문에 그 …

This study examined the spectral information and reflectance of cracks of an embankment
with drone-based hyperspectral imagery for crack detection. A Nano-Hyperspec mounted on …

This study develops a new device system for measuring a slope of object with non-adhesive,
non-contact and non-face-to-face, namely Inclinometer Slope Laser Measuring (ISLM), that …

Cracks in reinforced concrete structures are the most common type of damage and are used
as important analytical data to understand the fracture behavior characteristics of structures …

This paper reviews a method of measuring the tilted of horizontal angle of modular unit roof
that occurs during fabrication and site assembly phase using three-dimensional restoration …

요약 본 연구는 제방 균열의 탐지를 위해 드론 기반의 초분광 영상을 활용하여 균열의 분광정보
및 반사율을 분석하는것이 목적이다. 초분광 센서는 드론에 탑재된 Nano-Hyperspec 을 …

콘크리트 구조물의 균열은 장기간 지속 시 철근의 부식을 촉진시키므로 구조적 사용성을
보장하고 열화를 방지하기 위해정기적인 현장 점검이 필수적이다. 대부분의 시설물 안전점검은 …
