摘　　要：通过纹理处理技术来弥补图形绘制上的不足,是解决仿真场景中三维对象表面真实感的有效手段。在实际仿真场景中大面积纹理都是采用重复贴图技术,若需实现纹理多样化,需要美工手工制作,耗费大量时间和人力。提出了一种基于编码的大面积多样化纹理生成的方法,通过对源纹理图定义编码规则产生多个样图实例,在编码约束下根据场景需要可以随机无缝拼接成大面积的纹理贴图。为了增加拼接而成的纹理多样性,我们根据每个样图实例的编码规则在该样图中随机撒点拟合成噪声区域,再基于噪声区域进行该样图实例与噪声纹理的合成,使所产生的样图实例形态各异。It is an effective way to show realistic simulation scene by texture processing technology other than by graphic technology. Duplicate map technology, which wastes lots of time and human power, is used to generate large area textures in realistic simulation scene. A method of large area real texture synthesis was proposed based on random noise. This method firstly generated several samples by encoding the source texture graphics, and then randomly seamlessly spliced diverse large area texture maps under the constraint of the code rules according to the scene. With the purpose of increasing the texture diversity of slice textures, the noise area with random points was fitted under the constraint of different encoding rules of samples, then the synthesis of source texture and noise texture were made based on the noise area to generate diverse samples.
