摘要
以天宫二号伴星对组合体的观测任务为需求, 采用了一种基于OpenGL的伴星可见光相机成像仿真方法, 根据组合体、伴星的星历和姿态数据以及组合体3 ds格式三维模型, 设置了OpenGL透视投影成像模型参数, 结合组合体表面材质特性和可见光相机成像性能模型进行了处理和计算, 生成了组合体可见光仿真图像。通过与伴星实际拍摄的图像比较, 验证了文中方法的有效性和可信性。可为天基光学成像载荷设计与系统仿真、飞控任务安排等提供参考和依据。
Abstract
Aiming at the TG-02 accompanying satellite′s observation mission, the imaging simulation method of visible camera based on OpenGL was introduced. Based on the ephemeris and attitude data of the complex and the accompanying satellite, and 3 ds format of the complex 3D model, the parameters of OpenGL perspective projection model were set properly. Combined with the complex surface material properties and the visible camera imaging performance model, the complex′s visible image sequences were simulated. By being compared with actual observation images, the simulation method was proved to be effective and credible. This research can provide references for design and system simulation of space-based optical imaging payload, as well as the flight control task arrangement.
