基于虚拟现实技术的非煤矿山救护队培训系统设计与实现

摘要

针对非煤矿山救护队应急救援培训的实际需求和现实不足的情况,根据救护队行动程序,应用虚拟现实技术,研究与设计非煤矿山救护队应急救援培训系统.硬件系统采用可视立体技术和多点触摸技术,设计双屏触摸一体培训考试机.软件系统由用户信息管理子系统、多媒体演示培训子系统、专项操作训练子系统、考核与评价子系统、综合训练子系统构成.采用3D显示、人性化用户体验设计、自动寻路A*算法和导航网格等关键技术,从几何建模、动画建模、信息数据库和场景驱动等方面对系统整体进行架构.该系统的设计与开发可使非煤矿山救护队培训考核更加安全、高效、系统和节约.%Due to the actual demand and insufficient reality of emergency rescue training for non-coal mine rescue team, according to the action program of rescue team, an emergency rescue training system of non-coal mine rescue team was studied and designed based on the virtual reality technology.The visual three-dimensional technology and multi-touch technology were adopted in the hardware system, and an integrated training and examination machine with double screen touch was designed.The software system consisted of user information management subsystem, multimedia presentation training subsystem, special operation training subsystem, examination and evaluation subsystem, and comprehensive training subsystem.The overall structure of the system was constructed from the aspects of geometric modeling, animation modeling, information database and scenario driven by using the key technologies, such as 3D display, humanized user experience design, automatic pathfinding A* algorithm and navigation grid.The design and development of this system can make the training and examination of non-coal mine rescue team more safe, efficient, systematic and economical.
