为新一代成像导弹武器系统的研制提供目标光学仿真环境,需要进行光学特性仿真方法研究。从目标仿真系统的组成,即计算机图像生成软件、硬件,视频/光学图像转换器以及光学投影系统几方面,分析了各部分对可见光成像光学特性仿真的影响,并对其光学特性标校方法做了说明。在系统硬件确定后,调节图像生成软件中的三维模型的材质和纹理、场景中光源亮度、环境光亮度等是使仿真目标的光学特性与真实的相一致的有效方法。该方法已在导弹半实物仿真试验中得到应用和验证。
To provide the target optical simulation environment for the development of a new generation of imaging missile weapon system, the study of optical characteristics simulation method is needed. The influence of various parts on the simulation of optical characteristics of visible light is analyzed from the composition of the target simulation system, that is, computer image generation software, hardware, video / optical image converter and optical projection system. The calibration of optical characteristics is analyzed The explanation. After the hardware of the system is determined, adjusting the material and texture of the three-dimensional model in the image generating software, the brightness of the light source in the scene and the brightness of the ambient light are effective methods to make the optical characteristics of the simulation target consistent with the real ones. The method has been applied and verified in missile semi-physical simulation.
