基于GL Studio的仪表面板开发及其应用
|
摘要
运动的视景可以显示出飞机的位置和姿态,但视景没有直观的数据以供参考,所以在飞行视景中加入仪表是非常必要的。通过仪表的数据变化实时获取飞机准确的高度、速度、航向等信息,为研究无人机飞行运动过程提供直观事实依据。文章从仿真建模到软件模块的实现,较全面地介绍了一种专用虚拟仪表制作软件-GL Studio,以无人机座舱为例,详细说明了GL Studio的Active X代码实现技术及嵌入视景时的关键问题和解决方法。该软件在无人机半物理仿真试验中得到了很好的应用,满足了系统对实时性和流畅性的要求。
Flying scene of simulation can display location and position of the UAV.but there is no flying data to reference. So it is necessary to add the meter to the scene. the user can obtain the exact information of the plane based of the variation of the meter data,such as altitude 、volosity and heading.which provide intuitive and understandable warrant. A kind of expert construction software for virtual meter is presented at the aspects of modeling and realization of simulation modules.taking the UAV cabin as an example,the Active X code realization of GL Studio and key technologies and reality methods when embed in the scene are explained. this software behaves perfectly in the UAV half entity simulation trail, fulfilling the system requirement of liquidity and real time performance.
