三维组态软件场景导航图智能化建立方法研究

Research on Getting Intelligent Navigational Map of VR Scene Created by 3D Configuration Software

针对人在三维虚拟场景中漫游,容易迷失方向,以及在场景中查找目标耗费时间等问题,引入了导航图并提出一种智能化建立导航图的方法,通过实时获取三维虚拟场景的场景信息利用windows重绘机制来动态绘制场景平面投影图,提供给操作人员以图形化非编程的方式自动快速地建立相应三维虚拟场景的导航图;该方法融合了二维电子地图的宏观性以及三维场景的直观性优点;实验分析表明该方法能方便操作人员自动建立导航图,能指导操作者完成漫游任务,并能协助操作人员快速查找目标,提高了监控效率和人机交互能力。

An intelligent method of creating 2 D navigational map was proposed. Using Windows＇ redrawing mechanism redraw projec tion map of 3 D virtual scene, and it provides us a graphic and non programmed way to create correspond navigational map of 3-D virtual scene automatically. It＇s proved that the way of creating 2-D navigational map is effective, it can efficiently guide operator to accomplish vir tual environment walkthroughs and target finding fast. The way can improve the ability of human computer interaction of software.
