| 摘 要： | 提出了一种基于环搜索的盲台阶类特征识别方法。首先建立机械工程图二维正交投影视图的环描述,通过对盲台阶类特征的环构成的分析,定义能够反映盲台阶类特征的种子环,确定种子环的识别规则,从环集合中搜索符合特定规则的种子环,为盲台阶类结构特征的识别做好准备,然后,通过多视图的环匹配,实现盲台阶特征的识别。这种方法在实际 应用中取得良好效果,并可推广应用到具有类似特点的特征识别。

| Abstract: | Proposed a method for notch feature recognition based on chain description of 2D orthographic views of mechanical parts. First, chains are searched from input drawing data, and chain library is built Then notch feature is analyzed to obtain its special chain representations. After that, the chains that may reflect the notch feature are extracted from chain library according given rules, and used as seeds tn notch feature recognition process. By chain matching between corresponding orthographic views, the notch features are ex- tracted from input drawing data. The method gained a good effect in our experiment and could be applied for other feature recognitiom. |
