AI Technical Summary

Technical Problem

Existing conductor icing measurement equipment suffers from problems such as large errors and broken edge lines when faced with irregular cross-sections and complex backgrounds, making it impossible to accurately measure the major and minor diameters of the icing.

Method used

Images of the ice-covered body were captured by two sets of cameras at different positions and angles. Combined with color, infrared and blue light images, an improved HED algorithm was used for edge recognition and dynamic weight fusion to eliminate interference from guy wires and obtain accurate measurement data of the ice-covered body.

Benefits of technology

It can accurately measure ice covering circular and irregular conductors, improving measurement accuracy and robustness, reducing computational load, adapting to different lighting and fog conditions, and avoiding human error and safety risks associated with traditional methods.
