回转体线画图标记分析

线画图是人们之间以及人与计算机之间交换三维物体信息的主要来源之一。在计算机视觉研究领域中，线画图标记是对物体进行定性分析的一种有效方法，通过线画图的一致性标记，可排除许多不可能的物体结构，为线画图的定量分析减少工作量。曲面立休的线画图标记是一项非常困难的多作。回转体是一类特残的曲面立体，本文在前人线画图标记的研究成果基础上研究了回转体立体线画图的标记形式，得出了回转体线画图标记的新的节点型式。新的标记方法适用于由平面立体和回转体组合而成的复杂立体的线画图。

Analysing the labels for line drawing of revolving object

Line drawing is one of the resources of changing information on 3-D object between man and computer. In the study of computational vision, the labels of line drawing as an efficient method is to take part in quality-analysise of recovering the 3-D object. Consistent labeling can exclude many impossible configuration. Based on the current theories and previous ones, labels on the forms of junctions of the revolving object are presented in this paper. The rule applies to the compound body that is composed of polyhedron and revolving objection.
