A Method of Global Recogniting Circles about Engineering Drawing
Xian Zhang · 2003
In study on recognition of engineering drawings, the recognition for circle is a key technology. A new method of global recognition circle about engineering drawing is presented. Image of engineering drawing is processed. It depends on the circular arc of the image,the circle or circular arc is global recognized by tracing the circle direction and region. Experimental results show that the method is feasibility and availability.
