【摘要】 建立了空间关系的本体结构,在SRC-Ontology基于点集集合的8种拓扑关系表示的基础上,引入数学形态学算子,用基本的空间拓扑关系进行组合推理拓展,得到了点、直线、面三种空间目标间的6大类共43种拓扑关系表示,并程序实现了所提出的拓扑关系的判定。该表示方法比SRC-Ontology 8种拓扑关系表示更适合点、直线、面三类空间目标表示的需要,为空间拓扑关系建立本体模型提供了更加清晰明确的形式化表示基础,同时使得实际应用成为可能。更多还原

【Abstract】 An ontology knowledge representation model for spatial relation is established.Based on point set denotation of SRC-Ontology,arithmetic morphological operators is adopted,and a spatial topological relation widening representation method including 6 species,43 types of three basic spatial entities,namely points,lines,and areas,is proposed.This representation method not only wides SRC-Ontology’s 8 topological relation representation method,and provides more explicit formalization representation for spatial relation ontology modeling,but also make the practical application possible.The experimental result proves the feasibilities and validity of the proposed method.更多还原
