摘要： 提出一种基于知识的高精度机械工程图二维重建方法。在研究中,充分利用图纸中所蕴含的知识型信息,注重整体识别、模糊推理技术的运用,将图纸标准字符的理解和尺寸对图形的制约作用统一考虑。通过尺寸驱动方法,实现了从图像中重建几何信息及拓扑信息,进而对扫描图像进行精确的智能校正。

Abstract: A new method of reconstruction the higly precise 2-D engineering drawings based on know-ledge is investigated. During the research,we fully utilize knowledgeable information implied in the drawings,and focus on using the technique of fuzzy reasoning. Using the method of dimension drive, the geometrical and topological information is reconstructed from the image. Therefore,we rectify the engineering drawings with intelligent methods precisely.
