建筑物目标三维红外场景仿真

提出了建筑物目标三维红外场景仿真方法。首先分析了三维场景模型的生成方法,采用软件绘制的方法获取三维场景,并将其加载至OpenGL环境中进一步处理;然后分析了三维红外场景的生成方法,对辐射源进行三维模拟,建立红外成像模型,得到目标表面红外辐射特性;最后模拟红外热像仪生成目标三维红外场景,给出了仿真结果和温度对比曲线。实验结果表明,仿真图像真实地反映了建筑物目标的红外辐射特性,各部分温度与实测温度变化规律基本一致。本文所述仿真方法切实可行,达到了场景仿真的效果。

Simulation of building 3D infrared scene

This paper presents a simulation method of building 3D infrared scene.Firstly,analyzes the method of 3D scene model,which gains 3D scene by software drawing and loads it into OpenGL environment for further disposing.Secondly,analyzes the method of 3D infrared scene,which simulates the radiant point,builds infrared imaging model and obtains the infrared radiation characteristic of building surface.Finally,produces building infrared 3D scene by simulating infrared thermal instrument.It can be seen from the experiment results that simulation images truly reflect the infrared characteristics of building target and the change law between simulation temperature and measuring temperature is basically consistent.The simulation method is practical and feasible,which has reached the effect of scene simulation.
