Abstract

The invention provides a two-dimension and three-dimension integrated based transmission line corridor parameterized building method and system. The method includes the steps of S01, acquiring tower and insulator two-dimensional vector data, extracting elevation and line corridor three-dimensional data and acquiring topographic data; S02, calculating mount positions of an insulator and a transmission line relative to a tower by the aid of a model mount program of the insulator and the tower to form model mount data; S03, subjecting line corridor three-dimensional data to conversion processing to generate an shp file of ArcGIS; S04, subjecting models in a three-dimensional standard model library to comparing, editing, assembling and output processing to generate model data; S05, acquiring the topographic data and structuring a transmission line corridor scene according to the topographic data, the Shp file and the model data. Thee-dimensional modeling is short in period, working efficiency can be greatly improved, and two-dimension and three-dimension integrated applications are realized.

Description

technical field

[0001] The present invention relates to the field of electric power information technology, in particular to a method and system for parametric construction of transmission line corridors based on 2D and 3D integration, which are widely used in the 2D and 3D integrated display, application and management of transmission lines. Background technique

[0002] At present, there are two main methods for constructing 3D transmission line corridors. One is manual modeling based on drawings and collected information, and the other is design, assembly and modeling by using design software to call 3D standard models of transmission lines according to grid planning and design requirements. . The manual modeling method has a long cycle, high construction cost, and poor project reusability; the planning and design modeling method establishes a 3D standard model library for transmission lines, and builds a 3D model scene through model assembly, which greatly improves work ...
