Three-dimensional transformer station semi-automatic reconstruction method based on laser point cloud data

Abstract

The invention discloses a three-dimensional transformer station semi-automatic reconstruction method based on laser point cloud data. The method comprises the steps: according to the existing standard of an electrical apparatus in the electric power industry, by collecting point cloud data and texture data of a transformer station, constructing a high-reality three-dimensional standard mode library of the electrical apparatus of the transformer station; by combining with the existing standard model of the transformer station, based on the laser point cloud data, performing ground feature extraction and identification, and automatically acquiring a position and a gesture of the electric apparatus in space; putting the three-dimensional electric apparatus into a corresponding point cloud three-dimensional scene, thereby completing vectorization of the point cloud data and further completing three-dimensional reconstruction of a transformer station scene. According to the three-dimensional transformer station semi-automatic reconstruction method based on the laser point cloud data, semi-automation of the three-dimensional reconstruction of the transformer station is achieved, and manual interference can be reduced, so that the production efficiency is improved, and the production cycle is shortened; by utilizing the precision advantage of laser point cloud, the precision of model products can be improved, and the whole simulation degree is high.
