Research on Application of 3D Laser Point Cloud Technology in 3D Geographic Location Information Modeling of Electric Power

摘要

Three-dimensional laser scanning technology is a new surveying and mapping technology, also known as “real scene replication technology”, which can completely and accurately reconstruct scanned objects and quickly obtain original surveying and mapping data. Multi-site cloud data registration is an important link in 3D laser scanning data processing. The seven-parameter registration model based on control points with the same name is an algorithm model with high accuracy. Through piecewise low-order interpolation method, the curve smoothing processing of empty area model is realized, and then combined with the existing hierarchical detail model algorithm, the 3D model file of power equipment is loaded and rendered in the 3D scene. The purpose of this paper is to provide reference for the subsequent construction of power 3D geographic information platform.
