由三视图重建三维形体的研究

RESEARCH ON RECONSTRUCTING 3D OBJECT FROM THREE-VIEW DRAWING

本文提出了一个应用于工程图自动理解与重建的基于规则的专家系统。系统由动态事实库，静态规则库，推理控制和三维重建等四部分组成，通过采用规则表示法描述专家阅读工程图的知识和规则，根据读图思路建立推理机制。最后将理解结果在ＡｕｔｏＣＡＤ中进行三维重建。

In the paper, the auther put forward a regulation-based expert system which isused in auto -recognition and reconstruction of engineering graph. It collsists of four parts dynamic fact library, static regulation library, inference control and 3D reconstruction, it scribes the knowledge and regulations to recognize engineering graph with regulation expressing method, and sets up the inference mechanism according to its recognition thoughts.at last, it introduces recognition results of 3D reconstruotion with AutoCAD.
