Abstract

To address the problems of numerous blind spots, weak identification of hidden hazards, and low efficiency in traditional manual levee inspection, this paper conducts research on the application of UAV multimodal low altitude remote sensing technology in safety hazard investigation of river levees. Combined with the development characteristics and causes of typical levee hazards, the paper systematically analyzes the hazard identification adaptation mechanisms of visible-light, thermal infrared, and LiDAR remote sensing technologies, and constructs a standardized inspection technical system covering equipment selection, route planning, field operations, and data processing. Based on field application scenarios, the existing technical shortcomings are reviewed, and practical optimization paths are proposed. The results show that UAV remote sensing can achieve accurate investigation of both visible and hidden hazards in levees, effectively improve the intelligent level of levee inspection, and provide technical support for safe levee operation and maintenance.
