Abstract

The invention provides an underground cable three-dimensional scene construction method and an underground cable three-dimensional scene construction system based on an electric GIS platform. The underground cable three-dimensional scene construction method comprises the steps of: acquiring two-dimensional data and dimension data of a cable working well; acquiring basic framework three-dimensional coordinate data of the cable working well according to the two-dimensional data and the dimension data of the cable working well; acquiring three-dimensional coordinate data of each tube hole of an embedding unit according to dimension data and rectangular section coordinates of the embedding unit; converting the basic framework three-dimensional coordinate data of the cable working well and the three-dimensional coordinate data of each tube hole of the embedding unit into vector data; and constructing a three-dimensional scene of the cable working well according to the vector data. The underground cable three-dimensional scene construction method and the underground cable three-dimensional scene construction system achieves the rapid construction of the underground cable three-dimensional scene, significantly reduce modeling period and modeling cost of the three-dimensional data, and can realize the two-dimensional and three-dimensional integrated application.

Description

technical field [0001] The invention relates to the field of cables, in particular to a method and system for constructing a three-dimensional scene of an underground cable based on a power GIS platform. Background technique [0002] There are two main methods of constructing underground cables in the prior art. One is to perform manual modeling according to drawings and information collected on site; the other is to call the three-dimensional standard model of underground cables through design software to design and assemble according to the requirements of power grid planning and design. modeling. The first manual modeling method has a long period, high construction cost, and poor project reusability; the second planning and design modeling method establishes a three-dimensional standard model library for underground cables, and builds a three-dimensional model scene through model assembly, which greatly improves the The work efficiency reduces the 3D modeling cycle, but ...
