【摘要】：平显(Head Up Display,HUD)是飞行员了解飞行状态参数的重要仪器。它可以将飞行状态信息直接叠加在外界环境视景上,飞行员可以在兼顾外界环境的情况下了解动态飞行的状态。由于外界环境视景的颜色较为复杂,平显字符的颜色受外界视景的影响比较大,例如有战斗机会超低速飞行在森林等大面积绿色外界环境中时,常规的绿色平显字符颜色对比度低,容易造成飞行员的失误操作。所以研究平显字符信息的合理配色,改变不同平显字符颜色,可以减少飞行员的操作误差和视觉疲劳,提高完成作战任务的精准度和有效性。为了平显信息配色绩效进行考察,设计了一套模拟飞行测试系统,通过模拟动态飞行的过程中改变平显的字符信息颜色,飞行员在模拟测试中对平显的信息捕获容易性、颜色显示协调性、长时飞行适合性、整体画面效果进行评价,研究人员根据飞行员的绩效评价研究得出合理的配色方案,为平显的设计提供一定的试验依据。本测试系统采用OSG视景仿真软件对动态飞行场景进行开发,构建一个虚拟的飞行外部视景,OSG场景库提供高效的场景管理和图形渲染优化功能,可以满足动态飞行的真实感受,为飞行模拟提供了一个视景环境基础。然后采用IData软件对平显画面进行建模,主要对平显字符信息进行分块和颜色变量的定义,建模完成后加载到飞行视景仿真程序中,以平显作为第一视角在飞行视景中进行动态飞行。IData作为一套提供快速开发动态交互式的图形工具,它能够快捷地创建仪表,并能实时响应应用程序变量和控制事件,减少仿真中的图形开发和集成时间。最后采用JSBJim飞行方程解算飞行的姿态,对飞行员的各种飞行操作进行准确的动力学解算,使飞机的运动轨迹极可能的接近真实的飞行状态。试验结果表明,飞行员在测试过程中能很好的感受到颜色信息视觉对带来的影响,显示画面质量无抖动,无畸变,平显信息配色过程中无明显的视觉延迟,完全可以满足飞行员的测试需要。
[Abstract]:Head up display HUD is an important instrument for pilots to understand flight state parameters. The flight state information can be directly superimposed on the external environment, and the pilot can understand the dynamic flight state while taking account of the external environment. Because of the complexity of the color of the external environment, the color of the flat-display characters is greatly influenced by the external view.For example, when a fighter plane will fly in a large area of green environment such as a forest or other large areas of green environment, The normal green flattening character color contrast is low, easy to cause the pilot's error operation. Therefore, to study the reasonable color matching of flat-display character information and change the color of different flat-display characters can reduce the pilot's operating error and visual fatigue, and improve the accuracy and effectiveness of completing the combat task. In order to investigate the color matching performance of flat-display information, a set of simulated flight test system is designed. By changing the color of character information of flat-display in the course of simulating dynamic flight, it is easy for the pilot to capture the information of flat-display in the simulation test. Color display coordination, long flight suitability, overall screen effect evaluation, the researchers based on the pilot performance evaluation research to obtain a reasonable color scheme, for the design of flat display to provide a certain experimental basis. The test system uses OSG visual simulation software to develop dynamic flight scene, and constructs a virtual flight external scene database to provide efficient scene management and graphics rendering optimization functions, which can meet the real feelings of dynamic flight. It provides a visual environment basis for flight simulation. Then the IData software is used to model the flat-screen, which is mainly divided into blocks and color variables of the flat-display character information, and then loaded into the flight visual simulation program after the modeling is completed. Using flattening as the first angle of view, dynamic flight in flight scene. IData is a set of graphic tools to provide rapid development and dynamic interaction. It can quickly create instruments, and can respond to application variables and control events in real time. Reduce graphics development and integration time in simulation. Finally, JSB Jim's flight equation is used to calculate the attitude of the flight, and the accurate dynamic calculation of the pilot's various flight operations is carried out, which makes the flight trajectory of the aircraft very likely to be close to the real flight state. The test results show that the pilot can feel the influence of color information vision in the testing process, the quality of the display image has no jitter, no distortion, and there is no obvious visual delay in the color matching process of the display information. It can fully meet the test needs of the pilot.
