Method of fast acquiring 3D information of substation by using 3D laser scanner

Abstract

The invention provides a method for quickly acquiring three-dimensional information of a substation by using a three-dimensional laser scanner, includes such steps as: step (1), scanning internal equipment and external structure of substation by three-dimensional laser scanner, obtaining initial point cloud data of internal equipment and external structure information of substation, and obtaininggeographic position information data of substation by GIS, obtaining initial point cloud data of internal equipment and external structure information of substation by three-dimensional laser scanner,and obtaining geographic position information data of substation by GIS; step (2), denoising, smoothing and storing the initial point cloud data and the geographic position information data in the server, extracting the processed point cloud data and the geographic position information data from the server respectively, constructing a 3D fine model and a 3D landscape model of the substation. Theinvention has the advantages of high collection efficiency and high data precision: taking photographs of substation targets while collecting a large amount of point cloud data by using a three-dimensional laser scanner, and obtaining texture data to be used as texture map after modeling, thus shortening the data collection time and obviously improving the data collection efficiency.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a method for quickly acquiring three-dimensional information of a substation by using a three-dimensional laser scanner. 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,...

Problems solved by technology

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
