Level Classification Algorithm of Line Width Attributes Based on Borderline Dot Matching
Yongping Wang · Machine Design and Research · 2012
A layer recognition method of engineering drawings was presented.According to line width characteristic of engineering drawing,using contour tracing technology and matching algorithm to get borderline dot pair of target object.Introducing line width attribute characteristic factor,recognizing information of graphic element contour and linetype width gained in the process of picking by means of fuzzy recognition in order to achieve layering recognition of contour layer and assistant layer of graphic elements.The algorithm is validated by a instance,and it shows that the algorithm has good veracity,strong anti-disturbing,and little distortion,etc.
