| 摘 要： | 拓扑关系在抽象过程中的等价转换是维护多尺度空间关系一致性的基础。本文以空间拓扑关系组合推理所描述的线状目标之间的拓扑关系为例,采用成分抽象的等价转换方法,研究了线之间拓扑关系等价转换的原则,并绘出了相应的等价转换图。

| Abstract: | Abstract:Topological relations are very important in spatial relations,and equivalent transformation of topological relations is the base to maintain topological consistency.In this paper,in order to represent the equivalence of topological relations between two lines in vector space,based on topological relations between two lines,which are depicted by Combinatorial Reasoning of spatial topological relations,the authors investigated the questions of equivalent transformation of the basic topological relations types in abstraction process.The equivalent transformation methods on component abstraction are investigated,and then applied in the abstraction of topological relations between two lines.The corresponding equivalent transformation maps have been drawn. |
