摘要 研究了基于视图特征的机械类网格模型的搜索,为确定视图的投影方向和剖切位置,首先给出了改进的最大法线分布方法来生成模型的三个旋转无关主轴,并将该三个主轴方向分别作为模型三个正交剖视图的投影方向。在此基础之上,提出了一种基于轮廓图的序列剖视图自适应创建方法,用于生成有代表性的序列剖视图。通过实验验证了上述两种方法的可行性和有效性。 View-based feature for mechanical mesh model search was studied.In order to determine projection directions and cutting positions of sectional drawings of models,an approach named Modified Maximum Normal Distribution（M-MND）was proposed firstly for generating rotation invariant principal axes.Then three projection directions of model＇s orthogonal sectional drawings were set as directions of three principal axes respectively.On that basis,for the purpose of creating representative sequential sectional drawings,an algorithm named Silhouette-based Self-adaptive Creation Method（SSCM）for sequential sectional drawings was presented.The results from the experiments demonstrated the feasibility and effectiveness of proposed approaches.
