针对现有CAD领域的检索算法对模型的局部细节特征描述不足的现状
提出了一种基于最大公共子图的三维CAD模型检索算法
通过提取CAD模型的B-Rep信息
将模型用属性邻接图来表示.根据如果2个CAD模型存在相似的特征或局部结构
CAD模型所对应的属性邻接图应存在公共子图的原理
通过检测属性邻接图中的公共子图
得到了2个与CAD相似的局部细节特征
并利用这2个相似的局部细节特征对CAD模型进行了相似性评价.实验表明
该方法能够实现三维CAD模型检索
且检索的效率能够满足工程检索的要求
因此可以实现CAD模型设计和制造知识的重用.
Since the current retrieval algorithms cannot describe local features of CAD models detailed in the CAD field
a new one of 3D CAD model retrieval based on maximum common subgraph is proposed. Extracting B-Rep information of CAD models
the models are represented by the attribute adjacent graph(AAG). If two CAD models contain similar sub-parts
the corresponding AAGs ought to have common subgraph. According to this principle
the similar sub-parts are obtained by detecting the common subgraph of AAG. The similarity of the CAD models is evaluated by comparing the similar sub-parts. The experimental results show the efficiency of 3D CAD model retrieval to meet the requirements of engineering retrieval and reuse of design and manufacture.
