摘　　要：论文重点考虑近贴聚焦式像管结构的ICCD图像传感器,利用OSG渲染引擎设计了一套完整的微光视景仿真系统,支持实时并大量地生成多条件任意视角下逼真的微光影像,已基本达到国外成熟商业软件的要求。针对微光系统易受干扰的问题,论文模拟出场景依次叠加传感器调制传递效应、噪声因子和强光干扰后的成像效果,引入了图像的灰度均值、均方误差、信噪比、相关度等指标,完成对ICCD夜视系统抗干扰特性的定量评价。This article focuses on the ICCD image sensor with a close-to-focus image tube structure,and uses the OSG rendering engine to design a complete low-light-level(LLL)scene simulation system,which supports real-time and large-scale generation of realistic LLL images under multiple conditions and arbitrary viewing angles.Basically meet the requirements of mature foreign commercial software.Aiming at the problem of LLL system being susceptible to interference,this paper simulates the imaging effect after the scene is sequentially superimposed on the sensor modulation transfer effect,noise factor and strong light interference,and introduces the image's gray average,mean square error,signal-to-noise ratio,correlation,and other indicators,to complete the quantitative evaluation of the anti-interference characteristics of ICCD night vision systems.
