摘要
提出一种对工程图进行层次识别的方法。根据工程图样的线宽特征,利用轮廓跟踪技术和匹配算法,得到图中目标对象的轮廓匹配点对;再引入线宽属性特征因子,运用模糊识别的方法,对拾取过程中得到的图素轮廓信息及线型宽度信息进行模糊识别,实现对图形元素的轮廓层和辅助层的分层标识,并通过实例对该算法进行了验证。实践表明该算法具有准确率高、抗干扰性强、失真很小等特点。
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.
