空间红外下视系统的真实感红外场景仿真一直以来都是研究的一个难点。提出了一种基于卫星红外遥感反演数据的空间下视红外场景仿真方法。利用红外遥感反演数据,通过匹配算法获得仿真波段内地表红外纹理,建立了下视红外观测模型,对地表红外纹理图像在传感器焦平面上重采样,最后按照辐射传输理论,计算生成光学入瞳前红外场景。仿真结果表明:该方法可以逼真地模拟地物场景红外纹理特征。将热红外遥感反演技术应用于红外场景仿真,极大简化了大规模地表场景仿真过程,为空间下视系统红外场景仿真提供了一种直观、有效的新方法。
Realistic IR Infrared Scene Simulation of Space Infrared Vision System It has always been a difficult point to study. A simulation method of scene under infrared scene based on satellite infrared remote sensing inversion data was proposed. By using infrared remote sensing inversion data, the infrared texture in the simulation band is obtained by the matching algorithm. The infrared observation model is set up, the infrared image of the surface is resampled on the focal plane of the sensor, and finally the optical entrance pupil is calculated according to the radiation transmission theory Front infrared scene. The simulation results show that this method can simulate the infrared texture features of the ground objects vividly. The application of thermal infrared remote sensing inversion technology to infrared scene simulation greatly simplifies the large-scale surface scene simulation process and provides an intuitive and effective new method for system infrared scene simulation in space.
