虚拟环境红外物理模型研究

Research on Infrared Physics Model of Virtual Environment

分析了影响自然环境和人造建筑红外特性的各种因素,按照红外辐射的基本规律,建立了红外物理模型,环境的红外辐射图像和可见光图像是密切相关的,增添材料和气候信息,配合视景数据库中的环境、实体几何模型,可计算出观测环境的辐射亮度,最后转化为探测器图像。本文方法可提供包括自然背景、人造建筑在内的虚拟环境的红外探测器图像的显示,适用于动态变化的环境和目标。

Most factors effecting on infrared character of natural environment and cultural characteristics were analyzed. Infrared model was established according to essential principals of infrared radiation. Infrared radiation image is closely related to image of visible light. Radiation luminance of natural environment can be calculated using geometry model with material and weather information and converted to detector images. The method adapts to dynamically change environment and targets.
