摘　　要：针对现有建筑物三维成果缺乏形式化表达,不同专业获取的立面信息尺度单一,缺乏具体采集内容、规范不足的问题,本文从街区-单体-墙面3个尺度构建了建筑物立面特征元素及其之间的关系描述规范,提出了基于混合图模型的多尺度图结构建筑物立面特征表达方法,实现对建筑物立面的多尺度特征描述,并选取试验区域,依托Neo4j图数据库技术,从空间多尺度构建、立面特征实体构建和关联关系构建3方面构建建筑物多尺度特征模型。结果表明,通过将城市建筑物外立面的相关信息存入图数据库,可以实现数据的整合,使得原本分散、难以管理的数据变得集中、有序,同时图结构数据库的建立促进了数据的共享,提高了信息的流通效率和利用率。Addressing the issues of the lack of formal expression in existing achievements of the bulildings 3D model,the uniformity of facade information scales acquired by different disciplines,and the absence of specific norms for collection content,this paper constructs a normative description of building facade feature elements and their relationships from three scales:block,individual building,and wall.It proposes a multi-scale graph structure representation method for building facade features based on the hybrid graph model,which realizes multi-scale feature description of building facades.An experimental area is selected,and relying on Neo4j graph database technology,the construction of a multi-scale feature model for buildings is achieved through spatial multi-scale construction,facade feature entity construction,and relationship construction.The results indicate that by storing relevant information about the exterior facades of urban buildings in a graph database,data integration can be achieved,making originally dispersed and difficult-to-manage data centralized and orderly.The establishment of a graph structure database promotes data sharing and improves the efficiency and utilization of information flow.
