多源数据融合的大坝三维重建与隐患探测技术研究
Research on 3D Reconstruction and Hazard Detection of Dams through Multi-Source Data Fusion
摘要
Abstract
This study aims to construct a comprehensive three-dimensional visual digital model of reservoir dams through the integrated application of drone oblique photography and three-dimensional ground-penetrating radar technology,thereby enhancing the safety assessment and maintenance level of hydraulic engineering and promoting the application of digital twin technology in this field.By utilizing drone oblique photography to capture the external three-dimensional model of the reservoir dam and combining it with three-dimensional ground-penetrating radar to detect its internal structure,the study achieves precise localization and three-dimensional digital representation of hidden defects within the dam through point cloud processing and registration fusion.Data processing and analysis include multi-view image matching,three-dimensional radar slicing,and anomaly identification.The proposed multi-source data fusion method successfully constructs a comprehensive three-dimensional digital model of a reservoir dam,visually presenting both the external and internal structures of the dam,and accurately annotating the size and location of suspected voids within the dam body.This enables synchronous and intuitive representation of physical engineering,providing a scientific basis for dam maintenance and repair.The method not only improves the accuracy of safety assessments for reservoir dams but also offers technical support for the digital twin construction of hydraulic engineering.It advances the development of a digital twin reservoir dam simulation system with"four-pre"functions(prediction,prevention,preparedness,and response),significantly enhancing the operational resilience of reservoir dams and the informatization level of hydraulic engineering.关键词
