| 中文摘要: |
| 提出了一种基于机械零件模型骨架的检索方法.将零件库中提取的机械零件进行预处理去倒角、圆角以及圆孔等，保证处理之后得到无中空结构的零件模型；运用电场法对预处理后的零件模型骨架提取，得到完整的骨架模型；利用骨架树匹配计算出零件模型相似度.试验证明该方法能够快速实现零件模型骨架检索. |
| 英文摘要: |
| A method of skeleton retrieval based on machinery parts model is proposed.The mechanical parts extracted from the parts library are pretreated,such as chamfering,fillet and round hole,to ensure that the parts are not hollow after processing.The skeleton model is obtained by using the electric field method to extract the part model after the pretreatment.The similarity degree of the part model is calculated by using the skeleton tree matching test.The test proves that the method can quickly realize the skeleton retrieval of the part model. |
