摘　　要：通过分析目前三维重建的现状、方法及存在的问题,提出了一种新的三维重建的方法—工艺信息驱动下的三维工序模型重建。不再单从三视图出发,而从降低理解工程图纸难度方面着手,考虑图文结合,即利用电子工艺卡片中包含的大量工艺信息和工序图,通过语义理解、图纸识别理解以及知识推理等方法,重构出基于特征的中间工序模型。下面着重介绍工艺语言理解在重建中的应用。By analyzing the current status ,methods and problems of 3D reconstruction,Put forward a new method of 3D reconstruction the reconstruction of 3D process model driving by technical information. Not only start from three views ,but also think about reduce the difficulties of engineer drawings and combine the information of graphics and words. Using a lot of process information and sketches in the electronic process sheets,the process model based on features can be reconstructed through semantics understanding,drawing recognitions and understanding and knowledge reasoning. The applications of semantics understanding in the 3D reconstruction are mainly introduced.
