【摘要】：随着空间信息技术的快速发展及其在各个领域的广泛应用,三维GIS凭借其对空间数据三维属性的充分展示,己成为GIS发展的重要趋势并广泛应用于城市、地质等领域。矿山数字化与三维展示近年来已逐步成为三维GIS的重要应用领域。三维GIS凭借对空间数据的三维可视化和分析功能,在矿山数字化方面已逐步发挥着重要作用。现有矿井三维GIS主要开发方式有底层开发和二次开发。与底层开发相比,二次开发在GIS平台的基础上,对其功能进行灵活组合,并可使用其通用的数据格式,能更高效的进行开发。现有二次开发的三维矿山可视化系统大多着重于可视化功能,相关分析与管理功能较为欠缺,不能够充分满足矿井当中定制程度较高的功能需求。本文针对上述问题,在对矿井可视化相关功能进行分析之后,采用基于基础平台软件进行二次开发的方式,设计并实现了基于ArcGIS Engine的矿井三维GIS原型系统。并进一步提出和实现了定制程度更高的三维建模与可视化功能,提升了开发效率,实现了巷道三维建模、地层与钻孔建模、钻孔动态展示和剖视分析等功能。论文的具体研究内容和主要成果如下：(1)总结并对比了现有三维GIS与可视化系统及其在矿井数字化方面的应用成果,采用二次开发的方式,设计并开发了基于ArcGIS Engine的三维GIS系统,对其中功能与方法进行灵活组合和运用,实现了更为丰富的功能。(2)详细分析了基于Multipatch几何类型的三维模型的创建方法。提出根据巷道中心轴线进行巷道三维建模的方法,并进一步提出对多条巷道轴线交点处进行三维建模的算法,实现了巷道接头处的拼接建模。提出地层、钻孔、建筑等要素的三维建模方法以及纹理贴图方法。实现了地层剖视分析、巷道漫游飞行等功能。(3)设计并实现了基于ArcGIS Engine的矿井三维GIS系统。系统具备矿井三维场景显示与浏览、维建模与查看、场景注记、三维漫游、剖视分析等功能。
[Abstract]:With the rapid development of spatial information technology and its wide application in various fields, 3D GIS has become an important trend of GIS development and has been widely used in urban, geological and other fields because of its full display of three-dimensional attributes of spatial data. Mine digitization and 3D display have gradually become an important application field of 3D GIS in recent years. 3D GIS has gradually played an important role in the digitization of mines by virtue of 3D visualization and analysis of spatial data. The existing mine three-dimensional GIS main development way has the bottom development and the secondary development. Compared with the underlying development, the secondary development is based on the GIS platform, its functions can be flexibly combined, and its common data format can be used, so it can be developed more efficiently. Most of the existing 3D mine visualization systems are focused on visualization functions, and the related analysis and management functions are relatively lacking, which can not fully meet the high degree of customization in the mine functional requirements. In order to solve the above problems, after analyzing the related functions of mine visualization, a mine 3D GIS prototype system based on ArcGIS Engine is designed and implemented by the way of secondary development based on basic platform software. Furthermore, the functions of 3D modeling and visualization with higher degree of customization are put forward and realized, and the development efficiency is improved. The functions of 3D modeling of roadway, modeling of strata and borehole, dynamic display of borehole and dissecting analysis are realized. The specific research contents and main results are as follows: (1) the existing 3D GIS and visualization system and their application in mine digitization are summarized and compared. A 3D GIS system based on ArcGIS Engine is designed and developed. The functions and methods are flexibly combined and applied to realize more abundant functions. (2) the method of creating 3D model based on Multipatch geometry type is analyzed in detail. The method of 3D modeling of roadway based on the center axis of roadway is put forward, and the algorithm of 3D modeling at the intersection of many roadway axes is put forward, and the joint modeling of roadway joint is realized. Three-dimensional modeling method and texture mapping method for stratum, borehole, building and so on are presented. The functions of stratum dissecting analysis and roadway roaming flight are realized. (3) the mine 3D GIS system based on ArcGIS Engine is designed and implemented. The system has the functions of mine 3D scene display and browse, dimensional modeling and viewing, scene annotation, 3D roaming, dissection analysis and so on.
