| 摘 要： | 为了将二雏图纸在计算机中自动转换成三维模型并进行交互式显示和各种操作，必须首先从二维图纸中读取所有线条、标注等信息。将这些信息以合适的数据结构进行组织，然后根据这些数据识别相应的几何元素及其位置、尺寸等信息，即进行三维重建。该文对已有的多种三维重建算法进行分类和剖析，归纳出三维重建算法的主要技术难点，并给出了核心的内部数据结构。

| Abstract: | To automatically transform a 2D drawing to a 3D object and to display them interactively （or other operation）, the 2D drawing＇ s information such as all the lines and the labels should be read firstly. The information should be organized in a proper data structure, and then a 3D reconstruction can be carried on, which means to identify the corresponding geometric elements and their information. Various present 3D reconstruction algorithms have been classified and analyzed in this paper, then the main technique difficulties of 3D reconstruction algorithm have been concluded. A reasonable interior data structure is offered at the same time. |
