Abstract

The invention discloses a method for performing modeling on a substation based on point cloud data. The method comprises the steps that (1) the substation is divided into a plurality of areas; (2) the point cloud data of entities in each area is collected through multiple times of scanning; (3) the point cloud data of the entities in each area is spliced; (4) de-noising processing is performed on the point cloud data; (5) the de-noised point cloud data is diluted; (6) the point cloud data of the entities in each area is divided; (7) classified reconstruction is performed on the divided point cloud data to generate models corresponding to the divided point cloud data; and (8) the models corresponding to the divided point cloud data are spliced to obtain a complete substation model. Through the method, modeling can be performed on the substation with high quality, high precision, high efficiency and normalization to realize three-dimensional reconstruction of the substation, and a good basis is provided 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. Background technique [0002] With the development of 3D modeling and virtual reality technologies, substation informatization, digitalization, and intelligent supervision technologies are becoming more and more mature, and 3D visualization technology of substation real-world information has become a research hotspot. The 3D real scene modeling of substation is the technical basis of 3D visualization of substation, and the reconstruction of high-quality model is the key to realize more intuitive and real visualization effect of substation. At present, there are relatively few methods that can be considered for substation model reconstruction, mainly including the following three: [0003] (1) Modeling method based on virtual reality modeling language. [0004] Virtual Reality Modeling Language (VRML) is not only a modeling language, but also a scene langu...
