Title:
AUTOMATIC INSPECTION AND INTELLIGENT CORROSION DEFECT DETECTION METHOD AND DEVICE FOR SPILLWAY TUNNEL
Document Type and Number:
WIPO Patent Application WO/2024/040945
Kind Code:
A1
Abstract:
The present invention relates to the technical field of inspection and defect detection, and relates to an automatic inspection and intelligent corrosion defect detection method and device for a spillway tunnel. The method comprises the following steps: establishing a spillway tunnel corrosion defect database; establishing spillway tunnel corrosion defect analysis and evaluation standards and an early warning threshold; performing automatic inspection; and performing image analysis processing and intelligent identification model training. According to the present invention, the condition of a spillway tunnel can be automatically inspected, a corrosion type can be quickly identified, the degree of influence of corrosion is analyzed and determined, an early warning alarm prompt is given when the corrosion exceeds a threshold, and automatic and rapid early warning and prompting processing can be realized, such that downstream life safety dangers caused during flood discharge are avoided, the degree of intelligence is higher, the accident prevention capability is higher, the inspection efficiency and the detection efficiency are greatly improved, the labor costs are greatly reduced, and meanwhile safety accidents caused by personnel entering the spillway tunnel are avoided.
