LED球幕显示技术在飞行模拟器中的应用

Application of LED Dome Display Technology in Flight Simulators

当前飞行模拟器采用的视景显示系统大都基于投影器和投影技术的投影系统,故介绍一种新型的、以LED(Light Emitting Diode)技术为核心的LED球幕显示系统与应用。在解决了图形通道划分、灯板排布、图像分割和几何变形、高灰度控制驱动、全彩颜色匹配、非均匀度校正等技术问题后,LED技术和显示方法得以在球形屏幕中使用。LED球幕显示系统以超大视场、高分辨率、高亮度、高对比度和易维护等优势,展示出其在飞行模拟器视景系统领域的良好应用前景。

The current visual display systems used in flight simulators are mostly the projection systems base on projectors and projection technology,so a new LED(Light Emitting Diode)dome display system with LED technology as the core and its application are introduced.After solving technical problems such as graphics channel division,light panel arrangement,image segmentation,geometric deformation,high-gray control drive,full-color color matching and non-uniformity correction,LED technology and display methods can be used in dome screens.With the advantages of the super large filed of view,high resolution,high brightness,high contrast and easy maintenance,the LED dome display system shows its good application prospect in the field of the visual system of flight simulators.
