摘要
讨论直线的扫描变换,分析了在矩阵式液晶显示器上走样现象产生的原因,并介绍了几种常用的反走样方法,比较了这些方法的特点,在此基础上针对飞机坐舱系统的特点提出了基于飞机水平状态指示仪的快速精确的反走样算法,给出了未经过反走样处理和经过反走样处理绘制出的直线和圆的对比,此算法成功地解决了EHSI画面中罗盘刻度线在旋转时的扭曲抖动现象。此项算法已应用于多项机载液晶显示器,特别在枭龙飞机大屏幕液晶显示器上的应用取得了良好的效果。
The article discusses the linear scan conversion, analyzes the causation of aliasing, and introduces several ordinary way of anti-aliasing. Based on above research, it discusses the WU antialiasing technique and compares the lines draw by ordinary Bresenham algorithm and by WU antialiasing algorithm. Also the article analyzes the limitation of the WU antialiasing algorithm, and then advances the fast and accurate arithmetic of anti-aliasing about the aircraft horizontal attitude indicator. This accurate and algorithm of anti-aliasing has been realized successfully. This algorithm has been used successfully in the large area LCD, especially in FC-1 aircraft.
