摘要
采用概率统计方法和分形技术两种随机生成方法构造了天然地形的模拟图像 ;运用传热原理建立了天然地形红外热图像计算模型 ,探讨复杂地形红外热图像的简化计算方法 ,并将计算结果附于随机生成的天然地形图像之上 。
Both the statistical method and the fractal theory were used to numerically construct the simulated images of natural terrains. The IR feature model of natural tereains was established by using the principle of heat transfer, and a simple algorithm was proposed to calculate the IR irradiance of complex terrains. The IR images of natural terrains were simulated by embodying the numerical results of infrared radiation in the generated geometrical pictures of natural terrains.
