Abstract: With the idea of“Intelligence” in the underground space of power grid, the construction of intelligent pipe corridor is imperative. The underground optical fiber cable project is a hidden project, most of which can only judge the location of the underground cable channel by the ground signs. In this paper, a high-precision spatial measurement method for buried optical cable channels is proposed, and a visualization platform for buried optical cable 3D is constructed, to realize the operation and maintenance management of buried optical fiber cable towards high-precision coordinates, visual augmented reality management model, for the construction of smart tube gallery to provide a“Jilin sample.”.
