Realization of visual simulation of an aerial imaging platform

本文研究了基于小型局域网的航空成像平台飞行模拟仿真器视景系统的实现方法。对视景仿真系统的构成、视景仿真软件的开发、提高场景逼真度的建模方法和CRT-LCLV耦合成像机理进行了深入的研究,同时给出了利用离轴球面全反射镜无限远显示系统将产生的动态图像传送给航空成像平台这一行之有效的方案,并将这些技术应用到了航空成像平台飞行模拟器的视景系统当中。实验表明:将这些技术应用到航空成像平台的视景系统之后,视景图像的分辨率、亮度、逼真度和视场都有很大的提高,完全可以满足航空成像平台飞行模拟仿真器的视觉要求。

Based on a small LAN,an implementation method on visual simulation system of an aerial imaging platform on flying simulator is discussed in the paper.The content of visual simulation system is researched deeply including the structure of the visual simulation system,the development of software,the modeling method of increasing reality and the principle of CRT-LCLV integral imaging.At the same time,a better project is presented that the dynamic images are sent to the aerial imaging platform by means of off-axis spherical total reflection infinite display system.The technology is applied to the visual simulation system of the aerial imaging platform on flying simulator.Experiment result shows that resolution capacity,luminance,reality and field of view of scene images are increased obviously.It can meet visual requirement of the aerial imaging platform on flying simulator.
