doi:10.7523/j.ucas.2022.018

Abstract

Abstract: Power transmission lines in China are faced with safety hazards brought about by a variety of surrounding features, and line hazard investigation is of great significance to ensure reliable national power supply and power security. At present, various methods of line hidden danger investigation face different difficulties, and satellite remote sensing technology can provide a low-cost, non-contact and rapid solution. In this paper, we use satellite remote sensing technology to realize the identification and extraction of hidden dangers on the ground along transmission lines. A method is also proposed for the identification and extraction of hidden hazards along transmission lines, using multi-category residual refinement module for result correction, which reduces the cases of poor recognition of small-scale targets and category edge misclassification, and lays the methodological foundation for the practical application of satellite remote sensing technology to the investigation of hidden dangers along power transmission lines.

Key words: transmission line safety, extraction of potential surface danger, U-net, RRM_Mc
