摘　　要：研究和探讨了2D工程图特征识别关键技术之一——图形标注的识别机制和技术,并根据各类牙轮零件图特点分别采用了相应最优的方法进行图形标注的识别,提高了识别效率、准确性和可靠性。在此基础上开发了"三牙轮钻头特征识别系统",为回转类零件2D工程图的特征识别以及开发其他应用领域的特征识别系统提供了实用化范例。The realization mechanisms and technologies of drawing annotations are Studied and elaborated which is one Of keys of 2D engineering drawing feature recognition. Taking account of the characteristic of cone,the optimum approach is used to recognize the drawing annotations rapidly and availably. The three-cone bit feature recognition system is developed, which is a practical example of the feature recognition system for 2D engineering drawing of rotational parts and other application areas.
