摘　　要：分析了建筑结构图的工程对象类型和描述方式特征,针对建筑领域的典型实例提出了与机械三维重建不同的建筑工程三维重建方案。该方案按照最常用的结构制图标准,以DXF格式的结构图纸为处理对象,以AutoCAD二次开发为主要技术路线,选择了标准层平面图为主要对象视图。讨论了建筑工程对象的数据结构设计和重建微观策略,并给出重建结果的实例。The types of engineering objects and the ways of object description in 2D structure drawings of architecture engineering are analyzed. Then a method of 3D model reconstruction for architecture structure drawings is presented. The AutoCAD software is selected to deal with the DXF files of the structure drawings through secondary development manner. The floor drawings of the building are selected as the main objects to be processed. The preprocessing of the drawing data, the data structure of objects and some 3D reconstruction algorithms are discussed. The results of 3D reconstruction are given in the end.
