Research on Target Modeling Method for Aerial Transmission Lines Based on Laser Point Cloud Technology
This article studies the extraction of different ground features based on three-dimen-sional laser point cloud data of overhead transmission lines,using point cloud automatic classifi-cation(towers,grounding wires,ground,vegetation,etc.).Based on this,different tower type model libraries are established and feature analysis is carried out to achieve category extraction of towers and grounding wires,and precise spatial coordinates(X,Y,H)are extracted to achieve ac-curate positioning information acquisition of important inspection objects of overhead transmis-sion lines,And based on the three-dimensional point cloud data of transmission lines,a fully au-tomatic inspection trajectory planning for overhead transmission lines is planned,providing tech-nical support for the research of unmanned and fully automatic inspection technology for trans-mission lines.
