目标/星空背景光学特性仿真方法研究

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.

Optical characteristic simulation approach of targets/stars background

Research of optical simulation approach on targets optical environment simulation system was necessary for the requirement of new generation imaging missile weapon system development. The simulation system was usually composed of the computer image generation sorftware/hardware, video/ visible image convertor, and optical projector system. Effects of the above components on the optical characteristics simulation were analyzed, and the calibration methods of optical characteristics of the simulator were presented. With certain simulator hardware, adjusting the factors such as materials and textures assigned to the models, and the brightness of light source and ambient in image generation software was an efficient way to keep the optical characteristics of the simulating targets to be consistent with the real ones. The approach had been applied and verified in relevant missile test of hardware-inthe-loop simulation.
