【摘要】 说明了三牙轮钻头特征识别系统的研究内涵，并通过阐述三牙轮钻头特征识别的一般过程，介绍了其识别特征的方法，即基于规则的模板匹配方法。本系统研究与开发的为回转类零件2D工程图的特征识别，以及为开发其他应用领域的特征识别系统提供了实用化范例。更多还原

【Abstract】 The feature recognition system for three-cone bit is studied. On the basis of analyzing the process of the feature rccognition for threecone bit, the method of recognizing fcature-tem-platc matching based on rules is proposed. This system developcd is a practical exaniple of the feature recognition system for 2D engineering drawing of rotational parts and other application areas.更多还原
