利用数据挖掘技术对尺寸标注的信息提取

The Technique of Dimensions Information Extraction Using Data Mining

讨论了在AutoCAD中利用数据挖掘技术对尺寸标注信息进行提取的方法.通过数据挖掘技术的关联规则算法将搜索到的基本图元提取出来,然后根据其所属尺寸标注集合分别储存.通过这些基本图元可以对其尺寸标注属性进行识别提取,甚至可以还原爆破的尺寸标注.研究结果对实际数控编程中直接利用AutoCAD图形数据具有重要意义.

The technique of dimensions information extraction by data mining is discussed in AutoCAD. All the basic elements are searched and extracted through the association rules algorithm of data mining technology. Then according to the dimensions that they belong to, the basic elements are stored separately. The dimensions properties can be extracted by the basic elements, even the exploded dimensions can be restored. The research result has great significance in the numerical control （NC） programming using AutoCAD data directly.
