Abstract
Most of infrared scene models deal with backgrounds, they can't simulate infrared urban scene. This paper presents a global infrared image synthesis model for large-scale complex urban scene which can be applied to various weather conditions and suitable for various parts of the urban scene. We first analysis the influence of all kinds of meteorological and environmental factors on the infrared characteristic of urban scene. Then based on principle of energy equilibrium we propose a global infrared image synthesis model for urban scene, discuss the specific forms for various parts of the scene and compute their surface temperature. As the rendering principle for infrared scene differs from that for visible scene, we propose a novel rendering criterion for infrared scene. Finally by the method of Gouraud Shading of Computer Graphics, infrared images of urban scene from different viewpoints at different time are presented. Field measurement further shows that our model is robust and feasible.
