Implication

This approach demonstrates improved leakage detection in earth-rock dams using UAV technology and thermal infrared imaging, suggesting enhanced efficiency and safety measures.

Key Points

Leakage inspection accuracy significantly improved with the proposed thermal infrared remote sensing method, enhancing dam safety protocols.
Results indicated that temperature measurement accuracy is negatively correlated with distance and linked to surface reflectance values.
The method employed a dual-loop PID control combined with a boustrophedon method for efficient UAV navigation during inspections.
Implementing this technology can significantly reduce the labor and time needed to identify dam leakages, addressing safety risks associated with traditional methods.
