The precise and real simulation of the star scene in the astronauts training in manned space-flight would help the astronauts to recognize the spacecraft orientation and the orbital coordinates with respect to star positions, and to realize spacecraft maneuvering.In this paper, the problem of visual simulation of the star scene in space-flight training is discussed. A method for star scene simulation by means of planetarium is presented, and a mathematical model based on matrix theory for star scene simulation is developed. If the mathematical model is applied to control the motion of the planetarium with a computer at real-time, the astronaut in cockpit will see the exact and accurate star scene in simulated orbital flight.

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。
