针对火箭飞行过程中姿态数据的三维可视化绘制方法问题,首先介绍了姿态绘制常用的参考坐标系,然后给出了姿态数据的获取与处理方法,以及基于OpenGL图形库的姿态可视化绘制的三种建模方法及其算法原理(包括多次旋转法、地固系转角法、赤径赤纬法等)。最后给出了采用文中方法实现的原型软件的绘制效果图,证明文中算法是可行的。

As for 3D visualization rendering of rocket flying attitude, in this paper, some reference coordinate systems used for it were first presented. Then the method of getting and processing attitude data was given. Also, three modeling methods for attitude rendering with OpenGL were presented, including multiple rotations, using rotate angle in earth fixed coordinate system and using right ascension and declination angle. Finally, some visualization pictures of software using these methods were showed, which indicate that the algorithms are practicable.
