摘要 以投影视图模型理论为基础,通过对矢量工程图图元信息的智能化处理,依据各投影视图蕴涵的内在关联机理及工程图表达产品设计信息的规律,提出了投影域的概念并对其进行技术获取。根据工程图的投影规律和表达规则,研究了投影域间的逻辑关联关系。以投影域之间的逻辑关联关系为基础,给出了逻辑关系的判别算子;并研究了投影域逻辑关系获取算法。通过对投影域关联关系的获取,以投影域逻辑关联关系模型为基础,达到对工程图的检索评价。 Taking the theory of projective view model as the foundation, through the intelligent processing for the primitive information of vector engineering drawings, according to the intrinsic associative mechanisms implicating in the projective view, and the rules expressing the product design information of engineering drawings, the concept of projective region is put forward, and it be obtained. According to the projective sire disciplinary of engineering drawings, the logical associative relationships among the regulations and expres-projection domains are studied. Based on the logical associative relationship among the projection regions, the operator determining the spatial position relationship among projective regions is acquired. The acquisition algorithms of the logic associative relationship among the projective regions are studied.
