全罗盘画面是飞机座舱综合显示系统中重要的显示画面之一。其中一部分为随飞行状态变化以指示其正确位置的罗盘刻度盘。在飞机实际飞行中,罗盘跟随状态参数变化而发生旋转的频率很高,为使画面清晰显示,要求刻度盘上的刻度线在静态和动态旋转时不扭曲、不变形,为此,本文重点研究全罗盘刻度线的反走样算法。 (1)反走样算法的引出:用常规方法绘制出的罗盘刻度线会产生明显的锯齿,称之为走样。用于减少或消除走样的技术,称之为反走样。本文是采用算法来消除走样。 The all-compass image is one of the most important displays in the cockpit integrated display system. Part of it is a compass dial that changes with the flight status to indicate its correct position. In the actual flight of the aircraft, the compass rotates frequently with the change of state parameters. In order to make the picture clear, it is required that the tick marks on the dial are not distorted and distorted during static and dynamic rotation. Therefore, this paper focuses on Anti-aliasing algorithm for all-compass scale. (1) Derivation of anti-aliasing algorithm: Compass lines drawn by conventional methods will produce obvious jagged, called as aliasing. The technique used to reduce or eliminate aliasing is called anti-aliasing. This article is the use of algorithms to eliminate aliasing.
