提出了一种基于遥感信息的前视末制导地面目标红外场景生成方法。首先,利用遥感信息生成目标区域可见光三维场景,作为场景仿真的基础模型;然后,通过建立目标及背景的温度模型、红外温度-辐射模型,计算出目标及背景的红外辐射值,针对仿真目标区域的特点进行建模仿真。最后,采用了一种基于可见光纹理的背景真实感合成方法,增强场景的仿真效果。通过对比实测温度和红外实时图以及灰度相关匹配实验,结果表明,本文方法真实地反映了目标区红外辐射变化规律,具有较好的逼真程度。
A method of generating target infrared scene based on remote sensing information is proposed. Firstly, using the remote sensing information to generate the three-dimensional scene of visible light in the target area as the basic model of scene simulation. Then, the target and background temperature and infrared temperature-radiation model are established to calculate the infrared radiation value of target and background. The characteristics of modeling and simulation. Finally, a realistic background synthesis method based on visible light texture is adopted to enhance the simulation effect of the scene. The results show that the method of this article truly reflects the change rule of infrared radiation in the target area and has a good realistic degree by comparing measured temperature with infrared real-time image and gray-scale correlation matching experiment.
