Vega开发无人机模拟飞行视景系统

"某型无人机模拟飞行系统"是一个用于模拟无人机飞行的全任务试飞仿真系统,而视景系统作为整个仿真系统的终端显示平台,其开发的优劣直接影响到整个系统的综合性能;针对传统视景系统建模周期慢、仿真效果差等特点,提出了一种利用仿真软件Vega开发视景系统的方法,使用Creator中的"贯通面"、LOD、DOF技术建立了逼真的无人机和地景模型,Lynx搭建底层模型文件,基于MFC的Vega编程控制无人机位姿、视点、舵面偏转等,至此完成无人机视景系统的驱动;无人机试飞实验证明,该视景系统取得了比传统视景系统更好的效果。

Development of Visual System of UAV by Vega

UAV flight simulation system is a system used for simulating UAV's behaviors through whole tasks.The visual simulation system,which is the terminal of the whole simulation system,has a great effect on the quality of the whole system.As the traditional modeling method of visual simulation system takes too much time but still performances bad,thus the paper develops a visual system by using software Vega.Thus,technologies like LOD and DOF are utilized to build a vivid UAV model and a ground scenery model in Creator,and the substrate models files are edited by Lynx,while the attitude of UAV,the leaning of its control surface,and the settings of watching position are all managed by Vega based on MFC.Till now,the design of a visual system of UAV is completed conveniently,and the test result of UAV flight experiment shows it works better than visual systems built in traditional methods.
