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。
Motion of the scene can show the position and attitude of the aircraft, but the scene is not intuitive data for reference, so adding instrumentation in the flight view is necessary. Real-time access to the aircraft’s accurate altitude, velocity and heading information through data changes of the instrument provides an intuitive factual basis for studying the flight movement of the UAV. The article from the simulation modeling to the realization of software modules, a more comprehensive introduction of a dedicated virtual instrument production software-GL Studio, UAV cockpit, for example, a detailed description of GL Studio’s Active X code technology and embedded view When the key issues and solutions. The software has been well applied in the semi-physical simulation of UAV, which meets the requirement of real-time and fluent system.
