Power transmission line model slicing method

Abstract

The invention discloses a power transmission line model slicing method, which comprises the following steps of: performing global tile division calculation according to a data range of an original power transmission line model file to obtain tile identifiers of all tiles under all levels; acquiring power transmission line model data of a corresponding level according to the tile range, and cutting the power transmission line model data to obtain tile model data; traversing whether current tile model data exists in an original model slicing result library or not according to the tile identifier, and if not, newly adding the current tile model data to the original model slicing result library; if so, fusing the original tile data with the current tile model data; storing and updating the tile model data to obtain a model slice database; and re-organizing and outputting the model slice database according to the slice file format to obtain a power transmission line model slice data file. According to the method, data addition and local updating are supported, and the visualization efficiency of the three-dimensional data can be improved.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method for slicing a transmission line model. Background technique [0002] Lidar line inspection is widely used in power grids, and the point cloud accuracy is high, but the density of laser point clouds obtained by towers, insulators, various fittings, etc. is not ideal. In addition, the geometric accuracy of three-dimensional point cloud data obtained by lidar High, but the texture information of ground objects cannot be obtained. Accurate reverse modeling of transmission line towers and ground wires can make up for the lack of point cloud density or the lack of point clouds caused by occlusion and other reasons. The 3D model has continuous data, complete parts, and texture information. At the same time, it also causes problems such as large data volume, complex structure, and intermittent lines during 3D rendering. How to deal with the problem of data volume and d...

AI Technical Summary

Problems solved by technology

The 3D model has continuous data, complete parts, and texture information, but it also causes problems such as large data volume, complex structure, and intermittent lines when 3D rendering is displayed.

[0003] The existing transmission line model slicing is aimed at local data and does not support data addition and partial update. Some model data modifications must be reprocessed. After adding data, all data needs to be reprocessed. The data processing time is long, and there are problems when updating data and processing massive data. Complicated operations, low data processing efficiency, etc.

At the same time, the existing transmission line model slices a large amount of data, which will cause a large data burden to the subsequent 3D application, reduce the efficiency of 3D data visualization, and the visual effect is not good
