Real-time Imaging Simulation of Optical Earth Observation Satellites in Orbit

传感器成像仿真方法无法快速直观的获得给定时间和相应轨道的卫星传感器的成像结果,采用基于虚拟现实的模拟方法进行光学对地观测卫星在轨成像实时模拟,构建卫星在轨运行的虚拟空间环境,依照传感器的成像模型,将卫星传感器映射到虚拟空间环境中,实现卫星在轨成像模拟,加入成像误差模型,完成整个成像仿真。通过实验验证了方法的有效性,实验结果表明:该实时模拟方法高速、有效,能为相关研究提供仿真数据,为全链路动态实时遥感仿真奠定基础。

Currently, sensor imaging simulation method can’t acquire imaging results fast and intuitively, when the time and corresponding satellite orbit are given. For this reason, the method based on virtual reality was used for real-time imaging simulation of optical earth observation satellites in orbit, virtual space environment was built, in accordance with the imaging model of the sensor, the satellite sensors were mapped to the virtual space environment in order to achieve the imaging simulation of satellite in orbit, adding imaging error model, imaging simulation was completed. The experimental was done to verify the validity of the method. The experimental results show that： the real-time simulation method is speed, effective, it can provide simulation data for the research, and lay the foundation for the full link simulation of dynamic real-time remote sensing.
