최근 이상기후로 인한 급경사지 붕괴 위험이 증가되고 있으며, 급경사지 붕괴 위험의 사전 예측 및 경보 전파가 이루어지지않아 인명과 재산 피해가 발생할 수 있다. 본 논문에서는 급경사지의 상태를 평가하기 위해 IoT 센서와 AI 기반 카메라를융합한 급경사지 분석 시스템을 개발하였다. 시스템을 개발하기 위하여 급경사지 지반조건을 고려한 계측센서 하드웨어 및펌웨어 설계, AI 기반 영상 분석 알고리즘 설계, 그리고 예·경보 솔루션 및 시스템 제작을 수행하였다. IoT 센서의 데이터와AI 카메라 영상 분석을 통해 센서 데이터의 오차를 최소화하고, 데이터의 신뢰성을 향상시키고자 하였다. 또한 실제 급경사지에 적용하여 정확도(신뢰도)를 평가하였다. 그 결과, 센서 계측 오류는 0.1° 이내로 유지되었으며 계측 데이터의 전송률은95%이상이었다. AI 기반의 영상 분석 시스템은 야간에도 부분 인식률 99%의 높은 성능을 나타내었다. 본 연구결과는 다양한사회간접자본(SOC) 시설의 급경사지 상태 분석 및 스마트 유지관리 분야에도 적용할 수 있을 것으로 판단된다.
Abstract
Recent abnormal climate conditions have increased the risk of slope collapses, which frequently result in significant loss of life and property due to the absence of early prediction and warning dissemination. In this paper, we develop a slope condition analysis system using IoT sensors and AI-based camera to assess the condition of slopes. To develop the system, we conducted hardware and firmware design for measurement sensors considering the ground conditions of slopes, designed AI-based image analysis algorithms, and developed prediction and warning solutions and systems. We aimed to minimize errors in sensor data through the integration of IoT sensor data and AI camera image analysis, ultimately enhancing the reliability of the data. Additionally, we evaluated the accuracy (reliability) by applying it to actual slopes. As a result, sensor measurement errors were maintained within 0.1°, and the data transmission rate exceeded 95%. Moreover, the AI-based image analysis system demonstrated nighttime partial recognition rates of over 99%, indicating excellent performance even in low-light conditions. Through this research, it is anticipated that the analysis of slope conditions and smart maintenance management in various fields of Social Overhead Capital (SOC) facilities can be applied.
