基于三维建模和VRML的矿山网络虚拟现实技术研究与应用

摘要

运用矿业软件Surpac建立了凡口铅锌矿的地表、地层、断层、矿体和巷道的三维模型，并将所建模型复合形成了矿山DTM格式三维模型。通过格式数据接口转化为VRML所支持的WRL格式三维模型后，运用HTML语言编程实现网页中嵌入WRL场景文件，实现了基于网页的矿山三维模型浏览与交互，突破了矿山三维模型只能在专业软件中浏览的限制，对推广虚拟现实技术和指导矿山的资源评估、开采设计、运营调度以及灾害控制等具有重要意义。%A 3D model was created with Software Surpac for Fankou Lead⁃zinc Mine including terrain, stratum, fault, ore⁃mass and drift, which was then created in format of DTM. After that, it was converted to WRL format which can be transferred over internet by HTML programming, thus achieving 3D mine model being browsed and downloaded from website without using the professional software. It is important for virtual reality technology being popularized throughout mine and used in the mine′s operation activities, including resource assessment, mining design, mining scheduling and disaster control.
