摘要
提出并实现了一种应用于深空探测自主光学导航地面仿真实验的光学信号模拟器。该模拟器以高性能图形工作站、高分辨率LCD显示器和光学准直器为主要硬件,通过软件实现深空中光学信号源(恒星、大行星、小行星)的精确位置与光学特性的计算,利用OpenGL实现深空中天体的三维重建并投影到LCD显示器上,最后使用光学准直器实现平行模拟光信号的输出。实验证明该模拟器简单有效,可为新一代深空光学导航相机地面测试实验提供可靠的输入信号。
An optical signature simulator was proposed and developed for simulations and ground experiments of optical-based autonomous navigation sensors for deep space exploration. The simulator is mainly composed of high-class graphic workstation, high-resolution LCD monitor and optical collimator. The positions and optical characters of the signature sources such as stars, planets and asteroids in deep space are calculated by software firstly. Then, the 3d scenes including all illuminant celestial bodies in deep space are rebuilt using OpenGL and project to the LCD monitor. Finally, an optical collimator is applied to construct analog parallel signatures. The experiments show that the simulator is simple and efficient, and can be applied in simulations and experiments of optical navigation sensor for deep space explorations.
