【摘要】 提出了一种草地的真实感红外纹理生成方法:首先综合考虑材质组成、环境、气象等因素求解草地的温度分布.由于草地内部土壤和植被两组分的光谱特性存在较大差异,对二者的红外辐射特性进行分别求解;然后,从真实草地的纹理特征出发,建立纹理结构模型;最后,将已求解的草地的红外辐射数据映射到图像空间,得到具有真实感的草地红外纹理图像.实验结果表明,利用该方法生成的草地仿真红外纹理与自然界中草地的实拍红外纹理具有相似的细节特征,从而验证了提出的草地红外纹理生成方法的有效性.更多还原

【Abstract】 A new method is introduced to simulate realistic infrared texture of grassland.First,the radiative temperature of grassland is solved by integrating material composition,environmental and meteorological factors.As the spectroscopic properties of grass and soil vary greatly,the infrared radiation characteristics are computed respectively.Next,the texture structure of grassland is modeled based on the analysis of spatial distribution of natural grassland.Finally,the infrared radiance of grass and soil are mapped to image space and a realistic grassland texture is generated.Experiment results show that similar visual features exhibit between simulated textures and actual grassland textures,which justifies the effectiveness of the proposed method.更多还原
