摘要

摘要: 提出一种将OpenGL应用在目标红外辐射特性计算中,从而实现目标红外辐射特性可视化计算的方法.由于OpenGL可用于构造三维模型,进行三维图形交互软件的开发;因而将其引入红外辐射特性计算中可解决复杂目标计算问题,而且图形硬件的消隐能力避免了遮挡计算并使计算以所见即所得的方式实现可视化.针对目标红外辐射特性中的自身辐射和目标对太阳光的反射部分,分别运用光照模型中发射光和漫反射的特性,以像素的颜色获取温度参数和法矢从而实现可视化计算.用一个简单标准体模型进行验证,计算结果表明了该方法的有效性和可行性.

Abstract: A method of computing the infrared radiant intensity of complex target using OpenGL which achieved the visual infrared radiation calculation was presented. For OpenGL is able to be applied to construct the three-dimensional modal of objects and do three dimensional interaction, the evaluation of complex target-s infrared radiant intensity is available. Utilizing the hidden capability of graphics hardware, the computation of shelter was avoided and the radiant intensity then was obtained by WYSWYG(what you see what you get). Different visual light models were applied to get the self-radiation and the reflection of sun energy of target. The parameters of emission and diffuse reflection in light model determined the color of each pixel in computer screen and then the temperature and the normal of each pixel were obtained. So the computation was implemented visually. A simple model was applied to verify this method-s validity and feasibility.
