This paper addresses practical challenges in deploying UAV-Based Inspection for transmission lines in mountainous areas

including inadequate safety control

nonstandard data acquisition

and insufficient application of three-dimensional modeling. Drawing on years of inspection experience in mountainous areas

State Grid Jinzhong Power Supply Company develops a practical technical scheme covering safety control and typical inspection operations. For safety control

mandatory vehicle inspections

airspace approval

and dynamic geofencing serve as strict preflight requirements. Routine emergency drills for common faults in mountainous areas further reduce on-site operational risks. For typical inspection operations

the scheme establishes standards for visible-light imaging

increases the usability rate of infrared thermographic images to more than 95%

and applies lidar-based three-dimensional modeling to vegetation encroachment management. It thereby enables closed-loop digital management covering measurement

early warning

and hazard mitigation. Practical application shows that these methods support safe

standardized

and efficient unmanned aerial vehicle inspections of transmission lines in mountainous areas.
