摘要：

传统村落的布局优化是室外场景辅助设计建模的重要环节，由此提出了一种预测网络辅助下徽派 村落街坊布局生成方法。首先根据 CAD 测绘图提出徽派村落街坊的结构化数据构建方法；其次对局部布局中房 屋的各类别、位置和朝向分别设计预测网络；最后使用预测结果在已有的房屋数据集合中先根据面积和形状分类 进行房屋类别预测，再在相应类别中搜索最优生成结果，并满足区域内和房屋不重叠约束条件。通过一系列的定 量和定性实验结果表明，该方法能生成符合徽派村落街坊布局特征和规律的房屋布局，从而为设计者提供一个徽 派聚落场景的创作手段。

Abstract:

The layout optimization of traditional villages was an important part of the modeling of outdoor scene-aided design. Thus a generation method was proposed for neighborhoods layout in Hui-style villages with the aid of prediction network. Firstly, a structured data construction method was proposed for neighborhoods layout in Hui-style villages based on CAD mapping. Secondly, prediction networks were designed for each type, location, and orientation of houses in the local layout. Finally, the prediction results were used to predict the type of houses, which was conducted by firstly according to the area and shape classification in the existing house data set, and then by searching for the optimal generation results in the corresponding categories, and could satisfy the non-overlapping constraints within the region and houses. A series of quantitative and qualitative experimental results show that this method can generate a house layout that conforms to the characteristics and rules of the neighborhoods layout in Hui-style villages, so as to provide designers with a creative means for Hui-style settlement scenes. 

Key words: Hui-style villages, village layout, automatic layout, prediction network, layout optimization
