摘    要:设计了一种新型"助降灯臂"的图形界面,它通过2台大屏幕显示器来中心对称地显示角度指针光带,从而精确地指示横摇角度.设计在基于TMS320C6416双通道视频显示系统的基础上进行,采用了硬件上实现效率较高的改进的Bresenham多点直线生成算法,用C语言分别对左向和右向指针屏幕进行了编制了相应的直线生成程序,并给出了结果,实现了横摇指示的可视化.

关 键 词:中心对称  角度指针  横摇角度  Bresenham算法

Abstract:This paper designed a new type of graphic interface of landing-assistant device. It displays the angle signal pointing photic zone centrosymmetricly through a pair of big screen displays, so that it can show the transverse swing exactly. The design is based on the dual-channel video display system based on TMS320C6416, which adopts the effective improved Bresenham line-building algorithm on hardware, programming the line-building process in C language for the left -directed and fight-directed screens. The result shows that the transverse swing pointing can be visualized.
Keywords:centrosymmetry  angle signal pointer  transverse swing angle  Bresenham algorithm
