Abstract: It is an important measure to accurately and stereoscopically display the internal situation of the cable channel to realize the lean management of cable specialty and Digital transformation. Use 3D laser scanning technology to quickly obtain complete and accurate data of cables and channels. Use this data to accurately model cables and channels in 3D. Visually display the internal structure of the channel, cable route location, and routing. Solved the problem of not being able to express spatial logical relationships in two-dimensional GIS images. Provide technical support for cable operation assessment, fault analysis and diagnosis, and emergency rescue plan development.
