【摘要】：虚拟家装系统是一种虚拟现实仿真系统,其主要功能包括户型设计、户型装修、户型浏览及其它户型相关的辅助功能。本文的主要工作分为户型虚拟设计和户型虚拟装修这两部分。在户型设计方面,按照户型的设计步骤来描述：墙体的绘制,不同墙体的连接,房间的形成及户型的构造。在户型设计完成后,需进行户型装修。户型装修包括墙体、地板及天花板的装修,主要是在这些对象上铺贴如墙纸、瓷砖及木板等材料纹理,其中墙体装修还包括门窗的放置。同时也可以对户型进行软装修,即在户型中摆设家具模型。最后经过设计与装修可以得到理想效果的户型。同时,本文还对装修过程中使用到的材料纹理进行了比较深入的研究。采用灰度共生矩阵分析了墙纸纹理的周期性特征,并提出了纹理周期单元的自动提取算法。使用提取的周期单元作为户型装修的墙纸纹理,不仅减少了纹理图片的内存占有同时也保证了纹理铺贴效果的连续性。对于瓷砖纹理,主要研究了多个瓷砖材料拼贴问题。本文采用的方法：先计算铺贴规则(几何规则)的周期性,然后通过渲染到纹理的技术形成周期性的几何纹理,最后将几何纹理映射到目标区域。这种方式也能保证瓷砖纹理之间的连续性。同时,讨论了木板纹理的铺贴效果更真实化的情况。这些纹理问题的研究与解决方案的设计使得虚拟场景的材料装修更加真实化。
[Abstract]:Virtual home decoration system is a virtual reality simulation system. Its main functions include household design, decoration, browsing and other auxiliary functions. The main work of this paper is divided into two parts: virtual design and virtual decoration. In the design, according to the design steps: the drawing of the wall, the connection of different walls, the formation of the room and the construction of the household. After the completion of the household design, it is necessary to house decoration. Family decoration includes wall, floor and ceiling decoration, mainly in these objects such as wallpaper, tile and wood materials texture, including wall decoration also includes the placement of doors and windows. Also can carry on the soft decoration to the household type, namely furnishes the furniture model in the household type. Finally through the design and decoration can get the ideal effect of the Huxing. At the same time, the texture of the material used in the decoration process is studied in depth. The periodic feature of wallpaper texture is analyzed by using gray level co-occurrence matrix, and an automatic extraction algorithm of texture periodic unit is proposed. Using the extracted periodic unit as the wallpaper texture not only reduces the memory of the texture image but also ensures the continuity of the texture paving effect. For tile texture, the problem of multiple tile materials collage is mainly studied. The method used in this paper is to calculate the periodicity of the layering rules (geometric rules), then form periodic geometric textures by rendering to textures, and finally map geometric textures to target regions. This approach also ensures continuity between tile textures. At the same time, the more realistic effect of plank texture is discussed. The research of these texture problems and the design of the solution make the material decoration of virtual scene more realistic.
