摘要:
针对现有三维装配模型检索方法存在语义不符、准确性低、检索效率低等问题,提出一种融合装配信息的三维装配模型检索方法.首先,进行装配信息检索,利用符号化的编码表示装配信息,查找零件的编码以找出符合装配设计意图的三维模型.然后,利用装配零件之间存在的共轭关系,将装配零件的几何检索转化为查找符合共轭子图的属性邻接图,通过零件的属性邻接图进行模型检索.最后,利用频繁子图挖掘方法,提取出满足共轭子图的属性邻接图,用作模型的重用.实验结果表明:该方法能够较好地实现三维装配模型的检索,可以有效地支持面向装配零件的模型重用.
Abstract:
A 3D assembly model retrieval method based on 3D assembly information was proposed to deal with semantic mismatch, poor accuracy, and low efficiency in existing 3D assembly model retrieval methods. First, for assembly information retrieval, the assembly information was represented by the symbolic coding and the 3D models which conform to the design intention of the assembly were found by searching the code. Then, on the basis of the conjugation relationship among the assembly parts, the assembly model geometric retrieval was translated into a problem of finding attributed adjacency graph of conforming to conjugated sub-graph, and models were searched by model’s attributed adjacency graph. Finally, the frequent sub-graph mining method was used to search the attributed adjacency graph conforming to conjugated sub-graph for models reuse. Experimental results show that the method can effectively support 3D assembly model retrieval for assembly models reuse.
