面向扫描图纸的尺寸框架重建方法研究

Reconstruction Method of Dimension Frame for Scanned Engineering Drawings

本文在文本分割和像素矢量化的基础上,针对尺寸文本区域提出了一种尺寸标注框架的几何重建方法。首先介绍所采用的文本分割与扫描像素的矢量化方法,然后分析了机械工程图纸的尺寸标注特征与规律,详细介绍了文本区域驱动的尺寸标注框架的几何重建方法,最后给出了实验分析和结论。

Based on the text segmentation and pixel vectorization, a new approach for reconstructing the dimension frame from extracting text regions of the scanned drawings is put forward. First, text segmentation and pixel vectorization for scanned drawing are outlined, then the dimensioning characteristics and rules for mechanical engineering drawings are analyzed, and geometry reconstructed method for dimension frame driven by text region is described. In the last, experiment analysis and conclusions are given.
