Transformer substation three dimensional modeling method based on laser scanning

Abstract

The present invention relates to a transformer substation three dimensional modeling method based on laser scanning. The method comprises 1) a transformer substation 3D modeling demand obtaining step of obtaining the transformer substation internal equipment information, the external structure information and the geographic position information of a transformer substation; 2) a data acquisition step of using a three dimensional laser scanner to scan the transformer substation internal equipment and the external structure to obtain the initial point cloud data of the transformer substation internal equipment and the external structure information, and obtaining the geographic position information data of the transformer substation via a GIS; 3) a data processing and storage step of carrying out the de-noising and smoothing processing on the initial point cloud data and the geographic position information data and then storing the data in a server; 4) a step of extracting the processed point cloud data and the geographic position information data from the server separately, and establishing a transformer substation 3D detailed model and a 3D landscape model; 5) a step of fusing the transformer substation 3D detailed model and the 3D landscape model to obtain a transformer substation three dimensional model. Compared with the prior art, the transformer substation three dimensional modeling method based on laser scanning of the present invention has the advantages of being high in acquisition efficiency and data precision, being able to improve the transformer substation modeling precision, etc.

Description

technical field [0001] The invention relates to a modeling method, in particular to a three-dimensional modeling method of a substation based on laser scanning. Background technique [0002] As we all know, substations play a pivotal role in our modern life. It is a new trend in the development and application of the power industry to realize data collection and modeling of substations by means of information technology. However, due to the lack of existing data or data loss in actual production, the primary task of substation data modeling is data collection. The traditional data collection method is generally point-by-point collection, which cannot quickly obtain a large amount of spatial information, and there are problems such as difficulty in collecting points and very low operating efficiency, and the collected data can only be used routinely, and cannot fully provide the physical surface of the substation. model, but also exacerbated the difficulty of 3D modeling.

The traditional data collection method is generally point-by-point collection, which cannot quickly obtain a large amount of spatial information, and there are problems such as difficulty in collecting points and very low operating efficiency, and the collected data can only be used routinely, and cannot fully provide the physical surface of the substation. model, which also exacerbates the difficulty of 3D modeling

In addition, the display status of substation equipment and components widely used in my country's power system is a two-dimensional topology diagram and the corresponding connection diagram. To a certain extent, it provides a powerful reference for line maintenance and line inspection personnel
