摘要: 为了对建筑物间相互辐射影响的重要性进行评估,为多光谱仿真方法和ATR算法的研究提供理论支持,在3~5 μm和8~12μm两个波段分别进行了研究,并建立了建筑物间相互辐射影响的计算模型。当存在太阳直接辐射时,建筑物相互间的辐射影响在3~5 μm 波段可以忽略不计,而在8~12μm 波段相互影响明显,不能被忽略。建立了有两个冷却塔的虚拟场景,选取了8、9、10、11、12μm为研究波长,针对冷却塔间的相互辐射影响进行了数值模拟计算,其中8、9、10μm 三个波长的相互辐射影响较大,超过了总体辐射能量的10%,而11μm和12μm相对较小。对冷却塔间的辐射影响进行了场景仿真,仿真结果体现了不同波长的辐射影响随辐射距离的变化情况。
英文摘要: In order to evaluate the importance of the radiation influence between buildings and provide theoretical support for the infrared multispectral simulation method and ATR algorithm research, some research in waveband 3-5 μm and 8-12 μm was done and a radiation influence calculation model between buildings was built in this paper. When the direct solar radiation existed, it was not necessary to consider the radiation influence between buildings in 3-5 μm, because the influence was tiny enough to be ignored, while it should not be ignored in 8-12 μm because of the apparent influence. A virtual scene with two cooling towers was build and the radiation in 8 μm, 9 μm, 10 μm, 11 μm and 12 μm were selected to calculate the radiation influence between the cooling towers. According to the result, the radiation influence in 8 μm, 9 μm and 10 μm is greater than 10%, while that in 11 μm and 12 μm was smaller. The scene simulation for the radiation influence between the cooling towers is done, which shows the radiation influence at different wavelength with the changes of radiation distance.
