为满足仿真实验对高真实感目标红外图像的需求，提出了一种基于实测图像与三维数字仿真相结合的红外图像生成方法。通过测量获得物体表面实际辐射分布，以此为基础数据，建立真实温度分布的数学反演模型，生成目标红外纹理。再将纹理映射到几何模型，利用三维渲染技术生成高真实感红外图像。实验结果表明:该方法仿真灵活性高，生成的目标红外特征自然、准确，纹理细节丰富，图像实用性强。

Realistic infrared image generation method of target

To meet the great demand of realistic infrared images of target for simulation experiments, a realistic infrared target image generation method was proposed, which based on the combination of measured data and three-dimensional simulation. The surface radiation distribution of target was measured, which was used as input data to a retrieval model for target temperature distribution. Then the infrared textures of target were created using the retrieved temperature distribution, and mapped to a three-dimensional geometry model. The realistic infrared image was generated by 3D rendering technique. The experiments demonstrate that the generation method is good flexibility, and the infrared images are accurate in infrared feature, rich in texture detail and strong in practicality.
