摘要 根据几何元素间的典型关系 ,提出多种将面邻接属性图分解为更小的子图的方法 ,如利用内环、夹在几个邻接面之间的环等来分解面邻接属性图 为提高识别的速度和稳定性 ,依次采用如下步骤 :提取可识别的简单特征 ;根据序列的规则来区别未识别的子图并识别出复杂特征 ;最后用ACIS5 0中REM模块相应的函数检验所识别的特征 According to the specific relationship of geometrical elements, several methods are presented to decompose face adjacency attribute graph (FAAG) into smaller sub graphs For instance, inner loops, loop across several adjacent faces, etc are used to decompose FAAG To enhance the speed and stability of further processing subsequent steps involve: sorting sub graphs; extracting recognizable simple features; reorganizing the remaining sub graphs according to a set of rules and extracting complex features; validating the final feature model by REM (Remove Faces Component) function of ACIS 5 0 Benchmarks from NIST parts library are used to verify the effectiveness of our approach
