Transmission lines usually span vast geographic areas and pass through a variety of geographic environments

including mountains

swamps

deserts

and so on.These complex environments can lead to problems such as weather changes

traffic restrictions

flight safety and data collection difficulties.Therefore

an intelligent inspection method for transmission lines based on UAV multi-spectral images is proposed.The shape description operator is used to describe the characteristics of the transmission line inspection target

and an innovative enhancement algorithm is designed for the weak target of the transmission line to enhance the inspection target.Based on this

attention mechanism is introduced to improve the traditional YOLOv3 algorithm and identify transmission line inspection targets.Experimental test results show that the multi-spectral image enhancement effect of transmission lines under the research method is better

and the inspection time is shorter.
