Abstract

The invention provides a method and device for lightening coal mine three-dimensional model data. The method comprises the following steps: carrying out the blocking processing of the coal mine three-dimensional model data, so as to obtain a plurality of original data blocks; performing triangular surface simplification processing and texture multi-stage gradual-distant processing on each original data block to obtain a processed first data block; performing texture merging and geometric merging on each first data block to obtain a processed second data block; and performing texture compression and geometric compression on each second data block to obtain a processed third data block. According to the method, the coal mine three-dimensional model data is partitioned to obtain each data block, and triangular surface simplification processing, texture multi-stage gradually-distant processing, merging and compression processing are performed, so that the model data volume is reduced, the light weight of the coal mine three-dimensional model data is realized, the coal mine three-dimensional model can be quickly loaded by a front end, and the loading time of the front end is shortened.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular to a method and device for lightweighting 3D model data of coal mines. Background technique [0002] Coal plays an irreplaceable and important role in national economic and social development. Coal production has a long history, but the safe production of coal mines has always been a worldwide problem. In recent years, with the development of information technology, 3D models of coal mines can be constructed through surveying, especially for complex scenes of coal mines. Based on 3D models, the safety of coal mining can be improved. [0003] However, some coal mine 3D models have a relatively large amount of data, especially in complex coal mine scenes, the front-end loading time is long, or even cannot be loaded. Contents of the invention [0004] This application proposes a method and device for lightweighting coal mine three-dimensional model data. [0005]...
