介绍了红外成像仿真的基本理论,讨论了利用Vega传感器模块将输入的可见目标图像生成红外图像的技术。该技术使用Creator软件进行三维几何建模和纹理映射,使用TMM软件进行红外材质建模;然后,用Mat软件进行大气衰减的计算;最后,用SensorWorks软件进行传感器特性建模,通过光电转换生成红外图像。以阿帕奇AH6直升机为例进行了红外图像仿真,结果表明,利用Vega传感器模块进行传感器建模,建模效果较好,成本低,易于工程实现。

Infrared imaging simulation based on Vega

The basic principles of infrared imaging simulation was introduced, and a method for generating infrared images from visible images based on Vega was discussed. By the proposed method, the Creator was used to establish a 3D gemetric model and to realize a texture mapping, then the Texture Material Mapper(TMM) was applied to modelling for infrared materials. Furthermore, by using the Mat software, the atmospheric attenuation was calculated. A characteristic model of sensor was established by SensorWorks and infrared images were generated with photoelectric conversions. Finally, Apache AH6 helicopter was used in infrared simulation in this paper. The results show that the module established by Vega sensor has advantages in effective modeling, low costs, and the method is suitable for engineering practice.
