摘要
对地面目标红外场景仿真中使用的“点源法”和“面源法”这两种热源模型的计算方法、计算效率和仿真结果进行了比较与分析。仿真使用 Wavefront OBJ 文件目标造型数据,用 C++ 和 OpenGLAPI 实现了两种热源模型红外目标的温度场特性模拟,并绘制了仿真图像。仿真结果具备仿真对象的红外特征并进一步验证了两种热源模型的合理性。
We compare the heat transfer model of point-source method and slice-source method in ground-based object’s IR imaging simulation in term of computational method, algorithm efficiency and simulation results. The rendering pipeline, which is designed using C++ and OpenGL API, takes standard wavefront OBJ file as the object model data, simulates the temperature features of IR objects using the above mentioned heat transfer models, and generates the final IR images based on the simulated temperature data. The images have infrared characteristic of simulated objects and prove the validity of the two heat source models in another way.
