摘　　要：针对机载显示系统中图形变换最为耗时的全姿态指示仪画面,提出一种新的算法.该算法预测地平线各行的像素数,用水平线或竖直线作为扫描线进行填充,并在填充过程中实时计算地平线上各像素点的坐标,避免了建立地平线数组.与原有算法相比,减少了存储空间和计算量,提高了全姿态指示仪画面的图形变换速度.A new Mgorithm is presented for attitude indicator used in an aircraft cockpit to reduce the consumed time for graphics switching. The algorithm gets the coordinates of pixels in a horizontal scanning line and fills the graph with horizontal or vertical lines. This way, the horizontal buffer is not needed. Graphics in the attitude indicator are switched using less memory and less calculation time than the original algorithm.
