摘要
在研究空间相机成像效果探测问题时,针对提高探测相机成像真实效果的需要,研究了卫星表面光学反射特性的建模与仿真方法。利用双向反射分布函数(BRDF)仿真卫星表面的光学反射特性,将卫星表面物理特性与其光学反射特性有机地结合起来。在VC.Net环境下开发卫星表面光学反射特性仿真软件,并将软件集成到空间探测相机成像效果仿真平台上。利用平台进行成像仿真实验,生成真实感仿真图片。仿真结果表明,BRDF能够精确仿真卫星表面的光学反射特性,使成像效果仿真更加准确和逼真。
The approaches of modeling and simulating surface optical reflection characteristics of satellites to meet the need for the imaging effect simulation of the space exploration camera are explored in the research,which adopts Bidirectional Reflectance Distribution Function （BRDF） to simulate the optical reflection characteristics of the satellite surface with the organic combination of its physical and optical reflection characteristics,develops the related simulation software by employing the VC.Net,applies the software in the imaging effect simulation system of the space exploration camera and conducts the imaging simulation experiment based on the system to generate the simulation pictures with sense of reality. The Results show that BRDF can simulate the optical reflection characteristics of the satellite surface precisely and make the imaging effects of simulation system more exact and vivid.
