摘　　要：针对以前红外仿真方法细节差、实时性不高等技术难点,提出了一种新的红外物理模型实现方法。该方法将物理信息与物体的几何模型顶点绑定,提高了对红外场景的描述细节。该方法对物理模型的计算在CPU与GPU之间进行了分配,充分利用了可编程GPU的强大运算能力,有效提高了红外场景生成的实时性。讨论了几种典型探测器效应的添加方法。使用仿真图像来说明所提出方法的有效性,同时分析了该方法的优缺点。Considering the unsatisfied simulation details, low real-time quality and other technical difficulties of previous infrared scene simulation methods, a new implementation method of infrared physical model was proposed. In the method proposed, objects＇ physical information is bound to the vertices of their geometry model, which improves the description details of infrared scene. By distributing physical model＇s computation load between CPU and GPU, the new method makes full use of GPU＇s powerful computation ability, which effectively improves the real-time quality of infrared scene generation. Besides that, the add methods of several typical detector effects were also discussed. Finally, simulation images were used to illustrate the effectiveness of the proposed method, and the advantages and disadvantages of the proposed method were also analyzed.
