Method And Expression Of Complicated 3D Data Storage Model Of Orebody

The storage and expression high-precision complex 3D orebody model is an important content of digital mine.Relevant research more focuses on 3D data structure but not the distribute storage and Web expression.In order to solve this problem,the following research on storage and expression methods of complex orebody model is carried out:Analyzing the characteristics of drilling data and transverse drift data,discussing the matching problem between transverse drift data and orebody contour data,A constraint algorithm for surface modeling of orebody constrained by transverse drift data is proposed.In order to solve the problem of time-consuming in accessing the block data of 3D orebody,the 3D compression coding method and the storage method are studied.Linear octree algorithm is chosen as the model compression coding algorithm,and MongoDB is used as the distributed storage database.Combining the characteristics of the two methods,a pseudo-Morton code based on distributed data storage is proposed.Aiming at the problem of neglecting storage efficiency in mine 3D model system,a prototype system for storage and expression of 3D model is designed.The system uses Python as the background modeling language,HTML + JavaScript +.CSS as the front-end framework,builds Django server as the data transmission platform,and realizes the visualization of ore body model based on Three.JS of WebGL.The system provides model display,scene interaction and data retrieval functions.The orebody shape is determined by 3D surface modeling of the orebody,and then the orebody block modeling is carried out with the surface model as the constraint to generate 96,000 blocks.After the model generated,block segments are stored in distributed mode,and octree coding is used to search and verify in distributed database.The retrieval time is 1/5 less than that of file mode.Figure 37;Table 11;Reference 56...
