中文摘要：

提出一种结构构件三维信息的渐进式整合和规范化重组方法，将各种示意性的图形元素、多样化的表达方式、分散在多张二维图中的三维结构构件信息进行整合和规范化，得到具有严格几何对应关系的规范化投影图；同时．从构件属性标注中提取三维重建所需的隐含语义信息，在领域知识和经验的辅助下进一步应用到规范化投影图；最后，利用基于投影匹配的方法在规范化后的前视、侧视和水平投影图基础上完成精确重建．

英文摘要：

2D structural drawings are usually necessary to be converted to 3D models in various applications such as architectural design, building simulation, construction processes arrangement or quantity surveying. In this paper, we propose an improved method for 3D buildings reconstruction from construction drawings, which integrates construction information dispersed in multiple drawings based on an analysis to the characteristics of construction drawings.
