为研究动态飞行中外界环境色彩对平显显示信息的视觉影响,研制了一套平显信息配色绩效评价模拟系统。首先,采用IData软件对飞行导航平显界面进行建模,设置平显颜色字符块变量;其次,将建模生成的平显画面导入模拟飞行视景中进行飞行模拟测试,在模拟飞行过程中调用JSBSim模型对飞行操作数据进行动力学解算;最后,在测试过程中根据不同的飞行视景改变不同的平显字符块颜色进行模拟操作绩效的考察。模拟系统使用了OSG视景仿真软件包进行高逼真度视景仿真开发,大幅度降低了模拟系统的开发周期与难度。经过若干飞行员的模拟飞行试验,显示画面无抖动、无畸变,平显信息配色过程中无明显的视觉延迟,完全满足飞行员的测试需要。
In order to study the visual influence of external environment color on the information of flat display in dynamic flight, a set of simulation system of flatness information color matching performance evaluation was developed. First of all, using IData software to model the flight navigation flat display interface, setting the flat display color character block variable. Secondly, the model-generated flat display screen is imported into the flight simulation scene to simulate the flight simulation. During the simulation flight, JSBSim model is used to solve the flight operation data. Finally, the performance of simulation operations is investigated by changing the color of different flat display character blocks according to different flight scenes during the test. The simulation system uses the OSG visual simulation package for high-fidelity visual simulation development, greatly reducing the simulation system development cycle and difficulty. After a number of pilots simulated flight test, showing no jitter, no distortion, flat display information color matching process no obvious visual delay, fully meet the testing needs of pilots.
