Storage file structure of electric power three-dimensional data

Abstract

The invention relates to a storage file structure of electric power three-dimensional data, which adopts a custom binary format and comprises an initial block, an entry block and a data block, and theinitial block comprises basic information of a file; the entry block comprises an initial address for storing a data stream, a data stream byte number, a data stream type and a data stream module number; the data block comprises sub-data classification, content markers, the sub-data length and the sub-data block number, and storage of three-dimensional model data and three-dimensional point clouddata can be realized through custom expansion. Compared with the prior art, the electric power conventional data and the electric power three-dimensional data are stored in the same file format, unified storage of the multi-source data is achieved, the occupied storage space is reduced, model data unification between three-dimensional display platforms and unified reading of the multi-source dataare facilitated, the reading speed is high, and the occupied memory is small.

Description

technical field [0001] The invention relates to the field of information processing of electric power related data, in particular to a storage file structure of three-dimensional electric power data. Background technique [0002] Based on the three-dimensional power data, through three-dimensional visualization technology and spatial information technology, various information of the power system can be displayed in real time and intuitively, which is conducive to improving the quality of power grid management and operation efficiency, and reducing operating costs. Power 3D data mainly includes 3D model data and 3D point cloud data. These power 3D data are usually stored separately in 3D model format. Currently, common 3D model formats include obj, 3ds, max, ma, mb, c4d, md2, fbx, rwx, wrl, stl, dwg, etc., the above-mentioned 3D model format files are generated by corresponding software, and different power 3D data need to be stored in different files, occupying a large amou...

Power 3D data mainly includes 3D model data and 3D point cloud data. These power 3D data are usually stored separately in 3D model format. Currently, common 3D model formats include obj, 3ds, max, ma, mb, c4d, md2, fbx, rwx, wrl, stl, dwg, etc., the above-mentioned 3D model format files are generated by corresponding software, and different power 3D data need to be stored in different files, which takes up a lot of storage space

[0003] In addition, due to the complexity and particularity of 3D power data, the 3D display platform needs to read multiple 3D model files sequentially when extracting data, the loading speed is slow, and asynchronous loading cannot be performed, and the model data between 3D display platforms has not realized multiple Source data unification
