摘要
在联网飞行模拟训练中,飞机在编队或对抗中在观察邻近飞机时,被观察的实体在视景系统中会出现抖动现象,严重影响虚拟环境的沉浸感和仿真可信度。研究了抖动现象的产生原因和基本解决方法。指出帧不同步和相邻实体视点坐标转换是产生抖动的原因,结合了帧同步和平滑算法,并将算法和软件实现应用在某型飞行仿真器联网系统中。工程应用结果证明算法能有效地消除临近物体视景图像抖动问题。
Image jittering occurs in visual system of networked flight simulators, when fighters watch adjacent others in formation or combat. It destroys the feeling of reality and simulation reliability. The causes of it, frame asynchrony and coordinate transform, will be discussed, and then basic solutions will be investigated. The algorithms and software implementation have been used in a certain networked flight simulators system, with frame synchronization and smoothing algorithm used. The application results show that the methods can reduce image jittering efficiently.
