摘要
提出了一种实用的飞行器蒙皮红外辐射图像生成方法。首先是飞行器的几何建模与网格化并通过建立控制方程求解蒙皮温度场;其次,通过飞行器蒙皮红外辐射各单元面按深度排序后依次投影,实现了数据从三维空间到二维平面的转换,生成了各个角度的飞行器蒙皮温度分布图,进而计算辐射亮度并进行规格化处理。利用图像表达方式,实现飞行器蒙皮红外波段辐射亮度成像。实验证明,该方法简单实用,为研究飞行器蒙皮红外辐射分布提供了有效的表现形式。
The method of an aircraft skin infrared radiation imaging is proposed.First,the geometric model of the aircraft skin is built up with a grid.Temperature distribution of the aircraft skin is obtained by solving the control equations.Second,the aircraft skin infrared radiation data is transferred from three-dimensional to two-dimensional by element projections according to the ordering of their depth.The images of the temperature distribution are generated at various angles so that the radiance of aircraft skin can be calculated and normalized.Finally,the aircraft skin infrared radiance is described as a grey image.The experimental results have shown that the method is simple and practical and it provides an effective representation for the study on infrared distributions of the aircraft skin.
