【摘要】：平顯(Head Up Display,HUD)是飛行員了解飛行狀態(tài)參數(shù)的重要儀器。它可以將飛行狀態(tài)信息直接疊加在外界環(huán)境視景上,飛行員可以在兼顧外界環(huán)境的情況下了解動態(tài)飛行的狀態(tài)。由于外界環(huán)境視景的顏色較為復(fù)雜,平顯字符的顏色受外界視景的影響比較大,例如有戰(zhàn)斗機會超低速飛行在森林等大面積綠色外界環(huán)境中時,常規(guī)的綠色平顯字符顏色對比度低,容易造成飛行員的失誤操作。所以研究平顯字符信息的合理配色,改變不同平顯字符顏色,可以減少飛行員的操作誤差和視覺疲勞,提高完成作戰(zhàn)任務(wù)的精準(zhǔn)度和有效性。為了平顯信息配色績效進行考察,設(shè)計了一套模擬飛行測試系統(tǒng),通過模擬動態(tài)飛行的過程中改變平顯的字符信息顏色,飛行員在模擬測試中對平顯的信息捕獲容易性、顏色顯示協(xié)調(diào)性、長時飛行適合性、整體畫面效果進行評價,研究人員根據(jù)飛行員的績效評價研究得出合理的配色方案,為平顯的設(shè)計提供一定的試驗依據(jù)。本測試系統(tǒng)采用OSG視景仿真軟件對動態(tài)飛行場景進行開發(fā),構(gòu)建一個虛擬的飛行外部視景,OSG場景庫提供高效的場景管理和圖形渲染優(yōu)化功能,可以滿足動態(tài)飛行的真實感受,為飛行模擬提供了一個視景環(huán)境基礎(chǔ)。然后采用IData軟件對平顯畫面進行建模,主要對平顯字符信息進行分塊和顏色變量的定義,建模完成后加載到飛行視景仿真程序中,以平顯作為第一視角在飛行視景中進行動態(tài)飛行。IData作為一套提供快速開發(fā)動態(tài)交互式的圖形工具,它能夠快捷地創(chuàng)建儀表,并能實時響應(yīng)應(yīng)用程序變量和控制事件,減少仿真中的圖形開發(fā)和集成時間。最后采用JSBJim飛行方程解算飛行的姿態(tài),對飛行員的各種飛行操作進行準(zhǔn)確的動力學(xué)解算,使飛機的運動軌跡極可能的接近真實的飛行狀態(tài)。試驗結(jié)果表明,飛行員在測試過程中能很好的感受到顏色信息視覺對帶來的影響,顯示畫面質(zhì)量無抖動,無畸變,平顯信息配色過程中無明顯的視覺延遲,完全可以滿足飛行員的測試需要。
[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.
