基于视觉注意力分配的飞机驾驶舱人机界面布局优化

Layout Optimization for Aircraft Cockpit Man-Machine Interface Based on Visual Attention Distribution

以优化飞机驾驶舱人机界面布局设计为目的,提出了一种基于飞行员视觉注意力分配的布局优化模型。首先分析了计算机辅助三维交互应用软件(Computer aided three-dimensional interactive application,CATIA)中的可视域分析模块,给出不同视野区域的可视性等级,并对驾驶舱人机界面所在的视野范围进行栅格化处理;然后用G1法分析人机界面上各个设备的重要程度,并给予定量赋值;最后建立以飞机驾驶舱人机界面布局的视觉注意分配达到最优为目标函数的优化模型,并引入带有惯性权重的粒子群算法进行模型的求解。利用飞机模拟驾驶舱的人机界面布局为例,进行模型验证,结果表明该模型具有一定的可行性。
