摘　　要：针对复杂地面的红外仿真的需求,对地面的红外特性建模和仿真的效果进行了研究。针对复杂的地面场景,预先设置好材质编号和对应材质红外属性之间的映射关系,通过指定材质编号的方式手动对不同材质的区域进行分类。这样对于同一数据,针对不同的仿真谱段进行一次建模通过替换查找表的方式即可满足工程的需求。最后为了充分提高计算的效率,在GPU中进行红外辐射的实时计算,渲染输出的图像能满足工程需求。According to the demand of infrared simulation of complex ground, the modeling of infrared characteristic and effect of simulation have been studied. For the complex scene of ground,at first the material ID is maped to the infrared properties, then the material ID is specified to different regions of material manually. By the way, it can just model the data once and can satisfy the demand of different channels by replacing the look up table. Finally, in order to improve the computational efficiency, the calculation of infrared radiation is in the GPU, the output images satisfy the demand of project.
