摘要
采用基于开源三维渲染引擎Open Scene Graph(OSG)平台,利用目标与背景的几何特征模型、红外辐射特征模型、大气辐射传输模型、探测器光电转换模型、探测器噪声模型等,实现了一个参数可调的红外场景仿真系统。它能根据战情及被试装备的视角方向生成红外侦察告警注入式和辐射式仿真试验所需的红外场景图像。
Based on the principles of infrared imaging system, a 3 D infrared simulation framework was implemen- ted with OSG rendering engine in this paper. It includes the geometric characteristics of the target and background model, the infrared radiation characteristics of the model, atmospheric radioactive transfer model, the detector photoelectric conversion model and the detector noise model. This system can generate the IR scene image varying with the target speed, weather and the location of observer.
