一种采用数学形态学方法的姿态指示器填充算法
A Filling Algorithm for Attitude Indicator Based on Mathematical Morphology
【摘要】 在现代飞机座舱电子飞行仪表系统中 ,全姿态指示器天地区域的实时填充是个非常费时的工作 ,但已有算法不管是在填充速度还是硬件可实现性上都存在缺陷。本文把适于硬件实现的数学形态学方法应用于姿态指示器的实时填充中 ,提出了一种新的区域填充算法 ,在此基础上引入种子概念 ,发挥数学形态学的并行运算能力 ,提高全姿态指示器的填充速度。文中进行了单粒和多粒种子的生长试验 ,在多粒种子并行填充的情况下 ,填充效果和速度性能均优于传统算法。该算法填充速度快 ,能并行处理 ,适用于姿态指示器等实时填充的场合。
【Abstract】 The filling of sky and ground region in the attitude indicator of an aircraft electronic flight instrument system (EFIS) is a time consuming work. However, the old methods are not good in speed and hard to be achieved by hardware. A new filling algorithm is presented. The methods for mathematical morphology is applied to the filling of attitude indicator in real time. The concept of seed is then presented. The speed of attitude indicator filling is improved by the parallel operation of morphology. The growth experiment of single and several seeds is done. The performance of the new algorithm is better than that of the old algorithm in the case of several seeds′ experiment. This new algorithm has the features of high calculating speed, parallel processing and easy realization. Therefore it is adaped to the filling situations in real time, such as attitude indicator.
