三维虚拟姿态指示器设计

Design of Three-dimensional Virtual Attitude Indicator

姿态指示器指示飞行姿态角信息。提出一种基于三维图形学的三维虚拟姿态指示器实现方法,将姿态指示器的主体部分设计为姿态球结构;通过纹理映射技术绘制相应的刻度信息;使用Blinn-Phong光照模型增强姿态球的立体感。人机工效评价实验表明,三维虚拟姿态指示器人机工效指标评分较好,其中立体性评分为3.95,显著高于对照组得分。在ROC-RK3399-PC主板上进行三维虚拟姿态指示器的移植与验证,实现硬件平台国产化。研究证实,三维虚拟姿态指示器符合人机工效、通用性强,能够稳定运行于国产硬件平台。

Attitude indicator indicates flight attitude angle information.A 3 D virtual attitude indicator based on 3 D graphics was proposed.The main part of the attitude indicator was designed as the structure of the attitude ball.The corresponding scale information was drawn by texture mapping technology.Blinn-Phong illumination model was used to enhance the stereo sense of the attitude ball.The ergonomics evaluation experiment showed that the ergonomics index score of 3 D virtual attitude indicator was better,and the stereoscopic score was 3.95,which was significantly higher than that of the control group.The 3 D virtual attitude indicator was transplanted and verified on the main board of ROC-RK3399-PC to realize the localization of hardware platform.The 3 D virtual attitude indicator was ergonomic and versatile,and could run stably on the domestic hardware platform.
