摘要
应用海洋学和红外辐射理论的研究成果建立海面背景红外图像的仿真模型。在海面几何建模中,实现了对风浪和涌浪的模拟,同时增加了三角浪模型以增强真实感;红外辐射建模中,在保证图像质量要求下对辐射方程进行了适当简化。应用OpenGL技术实现海面红外图像的仿真,只需几个输入参数就可确定红外辐射特性,结果表明所提出的仿真模型是正确可行的。
Based on the research results of oceanography and infrared radiance theory, a simulation model of IR image with background of sea surface was proposed. In the geometrical modeling of the sea surface, the choppy waves were included to improve the quality of the simulated image besides the consideration of the wind waves and swell waves. In the modeling of IR radiance, the radiance equations were simplified with little deterioration of the image quality. OpenGL was used for simulation of the sea surface infrared image. The infrared radiation feature could be fixed with only a few input parameters. The result verified the validity of the proposed model.
