虚拟煤矿开发工具的设计及实现

Design and Realization of Virtual Coal Mine Developing Tool

针对虚拟现实技术在采矿领域应用过程中所遇到的问题,在充分分析煤矿系统的基础上,运用虚拟现实理论和技术及软件工程技术,设计了一个虚拟煤矿开发工具。该工具通过调用参数化模型并赋予一定的参数和属性,可以很方便的构建出各种虚拟矿井环境。设计了系统的框架结构,主要由人机界面,人机交互,场景生成和管理及模型库四部分组成。研究了系统实现的关键技术,这包括空间位置坐标系统的确立,节点模型库的建立,虚拟场景的数据构建及安全规程的校验方法。利用此系统开发了两个简单的虚拟矿井场景,证明利用此系统开发虚拟煤矿是可行的。

Aiming at the questions that were encountered in the course of applying virtual reality technology to coal mine fields, with virtual reality theory ＆ technology and soft engineering technology, a developing tool of virtual coal mine was designed on the base of coal mine system analyzed. It can easily construct various virtual coal mines by endowing parameterized models with certain parameters and attributes. Frame structure of the tool was presented, which is composed of computer-human interface, computer-human interaction, creation and management of scene and model base. Key realization technology of this system that included the space coordinates built, node model base established, scene structure expressed by data and safety rules checking was studied. Two coal mine scenes used the tool was developed, which proved it to be feasible to develop virtual coal mine using this tool.
