煤矿虚拟环境系统的总体设计及初步实现

提出了煤矿虚拟环境系统的总体设计，系统由四大模块组成，即数据管理、三维几何建模、构建煤矿虚拟环境和立体显示.其中，数据管理模块为整个系统提供数据；三维几何建模模块采用三维数据模型和数据结构表达地层、巷道和钻孔；构建煤矿虚拟环境模块采用一系列的虚拟现实技术构建虚拟矿山环境，使用户产生身临其境的感觉，并能与虚拟环境进行交互；立体显示模块借助虚拟现实设备产生立体视觉.此外，还提出了适合煤矿应用的三维数据模型和数据结构，初步实现了一个从底层开发的具有我国自主知识产权的煤矿虚拟环境系统的原型系统.

Design and primary implementation of coalmine virtual environment system

The overall design of virtual environment system of coalmine was put forward.The whole system includes four parts,data management,3D geometric modeling,generation of coalmine virtual environment and stereo display.Data management module provides data for system,3D geometric modeling module using 3D data model and data structure constructs model of stratum,roadway and drill,generation of coalmine virtual environment module using VR(virtual reality) technology constructs virtual mine environment which give users a feeling that they are personally on the scene,stereo display module using VR equipments realizes stereo vision of spatial object.In addition,3D data model and data structure,which are specially suited for coalmine application,were proposed.A prototype system of the self-authorized intellectual property right in our country,VRMine,was also implemented.
