摘要
在基于三维场景的管理信息系统中,摄像机作为人机交互的媒体直接决定场景对于管理人员的可视效果。针对全景摄像机控制方式选取问题,从位置和方向两个方面进行分析,提出了全景摄像机控制的两种改进方法。采用V irtools进行程序设计,通过实验测试表明,采用改进后的摄像机控制方法避免了操作人员对地形全貌观察的烦琐键盘操作,降低了对硬件性能配置的要求,增强了场景对于用户的可视效果,提高了管理工作效率。
As a media in interaction between human and computer,camera directly determines the visual effects for the scene in three-dimensional management information systems.Based on the analysis of two aspects of position and orientation on how to select the appropriate cameras,two sorts of methods on camera control are proposed.By use of Virtools for programming,and testing,it shows that the use of the improved camera control operator can avoid complicated keyboard manipulations on viewing terrain,reduce the performance of the hardware configuration requirements,enhance users＇ visual effects for scene,and improve management efficiency.
