在载人飞船的航天模拟中,正确而逼真的星象视觉模拟有助于航天员利用星位来判断飞船本身轨道飞行的情况,标识自身的空间方位,以及赖以进行机动飞行。 本文针对航天视觉模拟中,如何实现逼真的星象模拟问题进行了探讨。提出了一种采用星象仪实现星象模拟的方法。并应用矩阵理论,建立了一套星象模拟的数学模型。通过计算机解算数学模型,并实时地控制星象仪运动,将能使受训者在航天模拟中,看到精确而逼真的星空景象。
In spacecraft simulations of manned spacecraft, correct and realistic simulations of astrology help astronauts use the stars to determine the orbital orbit of their own spacecraft, identify their spatial orientation, and rely on maneuvers. In this paper, how to realize realistic star image simulation is discussed in space visual simulation. A method of star image simulation using star image instrument is proposed. Applying the matrix theory, a mathematical model of astrological simulation is established. Solving the mathematical model by computer and controlling the astronomical movement in real time will enable trainees to see accurate and realistic images of the stars in space flight simulations.
