| 摘 要： | 提出一种从二维视图到三维几何模型转换中视图的包围盒分离方法，通过考察图纸中图元的包围盒之间的相交情况进行视圈分离。与现有的视图分离方法相比，充分利用了转换中所需要的数据结构，与视图的边界曲线状况无关。利用基本视图之间的投影关系进行视图识别。给出一种面向二维视图到三维几何模型转换的数据结构和3个视图分离识别的例子。 |

| Abstract: | A box-based approach is presented for views separation in reconstruction of 3D objects from orthographic views, which separates views through analyzing the intersections between rectangular boxes of edges. It makes use of data structure needed by 3D reconstruction and has no relation with the views boundary compared with other methods existing. Views are identified through the projective relationships of orthographic views. A date structure for reconstruction and three samples of views separation and identification are given. |
| Keywords: | D reconstruction Orthographic views View separation View identification |
