Abstract

The invention discloses a method for modeling substation GIS equipment based on point cloud data. The method comprises the steps of: (1) collecting the point cloud data of the substation GIS equipment by adopting a method of multiple scanning; (2) splicing the point cloud data of the substation GIS equipment 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) segmenting the point cloud data based on an actual structure of the substation GIS equipment; (6) classifying the segmented point cloud data according to classification indexes of the point cloud data; (7) carrying out model classification reconstruction based on the classified point cloud data; (8) and splicing the obtain a complete substation GIS equipment model. The method disclosed by the invention can be used for modeling the substation GIS equipment precisely and efficiently so as to realize three-dimensional reconstruction of the substation GIS equipment, 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 substation GIS equipment. Background technique

[0002] In the power industry, GIS refers to sulfur hexafluoride enclosed combined electrical appliances, which is called "Gas Insulated Switchgear" (Gas Insulated Switchgear) internationally, or GIS for short. It organically combines the primary equipment in a substation except the transformer, including busbars, circuit breakers, current transformers, voltage transformers, isolating switches, lightning arresters, etc., into a whole through optimized design. 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 3D reconstruction of the real scene of the substation, it is necessary to accurately and efficiently perform 3D reconstruc...
