摘要
提出轴类回转体的分层识别方法,该方法首先提出工程图的基本图元几何关系的描述;其次先识别出轴类图形如通孔、键槽之类的细节特征和折断线省略画法,然后去除它们;最后识别回转圆柱体。
A method about hierarchical recognition to the objects of shtrfi revolution is presented. In this method, firstly a description about geometric relation of the basic drawing elements in engineering drawing is provide＆ Secondly, after recognized the detail feature- such as hole, keyway -and the splint brushwork, a work to clear them is done. Finally a recognized work to the revolution cylinder is completed.
