CCTV 영상 기반 모니터링 및 AI 실시간 침수 예측 모델링을 통한 건설현장 침수 위험 관리 = Construction Site Inundation Risk Management through CCTV-Based Monitoring and AI Real-Time Inundation Prediction Modeling

다국어 초록 (Multilingual Abstract)

This study aims to develop a real-time inundation prediction system using CCTV at construction sites. A model was established to estimate inundation depth from CCTV, and its performance was validated by comparing the estimated inundation depth with observed data. The results demonstrated a high correlation (R2 = 0.99) and an RMSE of approximately 3 cm, confirming the feasibility of using CCTV for quantitative inundation monitoring. Furthermore, a real-time inundation prediction method for vulnerable areas was proposed. inundation characteristics derived from XP SWMM simulations were used to train a model based on ANN (Artificial Neural Networks) and CNN (Convolutional Neural Networks). The model's performance was evaluated using the Mean Absolute Percentage Error (MAPE), with overall average error rates of 8.89% for inundation area predictions and 19.49% for grid-based inundation depth predictions. Future efforts will focus on integrating real-time CCTV inundation monitoring with the AI model to enhance its predictive accuracy.
