摘要建筑群模式识别对于理解和建模城市空间具有重要意义。然而,现有的许多方法不能充分利用空间信息,难以有效地处理复杂程度较高的地形数据。设计能够直接作用于地形数据以提取空间特征的智能计算模型是至关重要的。为此,我们提出了一种新的基于图卷积的深度神经网络来自动识别任意形状的建筑群模式。该方法首先利用一般图对建筑物进行建模,然后利用神经网络同时学习建筑物的结构信息和顶点属性来对建筑物进行分类。将该方法应用于实际建筑数据,实验结果表明,该方法能够有效地获取空间信息,比传统方法做出更准确的预测。
ABSTRACT Recognition of building group patterns is of great significance for understanding and modeling the urban space. However, many current methods cannot fully utilize spatial information and have trouble efficiently dealing with topographic data with high complexity. The design of intelligent computational models that can act directly on topographic data to extract spatial features is critical. To this end, we propose a novel deep neural network based on graph convolutions to automatically identify building group patterns with arbitrary forms. The method first models buildings by a general graph, and then the neural network simultaneously learns the structural information as well as vertex attributes to classify building objects. We apply this method to real building data, and the experimental results show that the proposed method can effectively capture spatial information to make more accurate predictions than traditional methods.
