Jiayi Zhang · Jisuanji gongcheng · 2011
Characteristics of the title panel and title block forms is analyzed in the engineering drawing files.Reasoning and judging can be realized according to certain logic rules,thus it can divide the frame into different region son block forms.Based on characteristics of forms,new methods are proposed to search sub table and recognize corner points of the title panel and title block region.Utilizing methods of sub table searching and words matching,region division and width recognition of the title panel and title block are realized.The application instance shows the validity of the method.
