摘要
针对座舱内的多功能显示器和平视显示器(HUD)的结构特征,设计了一个结构简单的瞄准线测量系统,它由装在头盔上的摄像机、座舱结构特征和处理器组成。首次提出了利用可以高精确提取的HUD和多功能显示器的结构特征配合正交迭代算法(OI)解算相机位姿,最后转化为瞄准线的测量方法。根据座舱特点,进行了一系列的仿真实验。仿真结果显示该系统的测量精度很高,并且验证了所设计的基于座舱结构特征的瞄准线测量方法是合理的和有效的。
Taking the structural features of Multi-Function Displays（ MFDs） and the Head-Up Display（ HUD） in the cockpit into consideration,we designed a Line of Sight（ LOS） measurement system with simple structure,which was composed of a camera fixed on the helmet,a processor,and cockpit structural features. A new method was proposed which used the accurate structural features of MFDs and HUD together with Orthogonal Iterative（ OI） algorithm to obtain the camera pose,which was then translated into LOS. A series of simulation experiments were made according to the cockpit structural features. The simulation results showed that： 1） the system has a high measurement accuracy; and 2） the method based on cockpit structural features is rational and effective.
