Method of modeling substation bus based on point cloud data

Abstract

The invention discloses a method for modeling a substation bus based on point cloud data. The method comprises the steps of: (1) collecting the point cloud data of the substation bus by adopting a method of multiple scanning; (2) splicing the point cloud data of the substation bus obtained through multiple scanning; (3) performing de-noising processing on the point cloud data; (4) performing rarefying on the de-noised point cloud data; (5) extracting N arbitrary cross section circles of the bus based on the point cloud data after rarefying, and acquiring a radius and a circle center of each cross section circle; (6) calculating an average value R of the radii of the N cross section circles based on the radius each cross section circle, and regarding the average value R as the radius of the bus; (7) and establishing a bus model based on the radius of the bus and a bus extension trajectory. The method disclosed by the invention can be used for modeling the substation bus precisely and efficiently, and provides a good basis for three-dimensional visual and intelligent supervision of the substation.

Description

technical field [0001] The invention relates to a modeling method, in particular to a method for modeling a substation bus. Background technique [0002] Bus bar refers to products made of high conductivity materials such as copper and aluminum to transmit electric energy, collect and distribute electric power, and is the main conductor for power station and substation to transmit electric energy. Usually, the electric energy output by generators, transformers or rectifiers is transmitted to various users or other substations through the busbar. At present, 3D visualization and intelligent supervision of substations have been valued by people in the industry, and 3D reconstruction of substation real scenes is the basis for realizing 3D visualization of substations. In order to realize the three-dimensional reconstruction of the real scene of the substation, it is necessary to carry out accurate and efficient three-dimensional reconstruction of various equipment inside the s...

Problems solved by technology

However, these applications are limited to the modeling and measurement of some simple regular objects, such as building modeling with a single boundary, public facilities modeling with a single structure, and measurement of distance, height, volume, etc., and rarely involve the reconstruction of complex models

In view of the particularity of the substation structure, some modeling methods in other fields cannot be easily transplanted to the reconstruction of the substation model. Directly using modeling methods in other fields to reconstruct the substation model will cause problems such as poor model accuracy and missing details.
