摘要
本文介绍一种面向工程图样的图形预处理方法,利用工程图样语义分析的两方面对图形进行预处理,其一,通过尺寸标注中的文本信息判断轮廓线的特征属性;其二,利用图线信息理解剖视图类型。经过图形预处理,工程图样中被破坏的体素轮廓线得到补全,为后续的三维重建打下了良好的基础。
A new oriented—3D reconstruction preprocessing of engineering drawings is presented in this paper.First,with the help of dimension text,the feature styles of outlines is judged auto- matically.Second,styles of sections are understood by using meaning of lines in engineering drawings.The broken outlines of primitives are repaired after the preprocessing,which is the basis of 3D—reconstruction.
