空间方向关系的反转运算

反转运算作为空间方向关系最为基础的一种运算,目前对其研究还没有达到形式化和系统化的要求。这里以空间方向关系的集合表示为基础,在严格定义方向关系的前提下,从点状目标间方向关系的反转运算出发,分类研究了各种矩形主方向关系的反转运算规则,对两目标出现重合区域的方向关系进行了重点研究,给出了运算结果并予以证明。

Research for Inverse Operation of Spatial Direction Relation

Inverse operation is one of the basic operations for spatial direction relation.Recently,research for inverse operation cannot meet the need of formalization and systematization.In the paper,spatial direction relation was firstly defined strictly based on the set representation of direction relation.Inverse operations of different rectangle cardinal direction relations were classified and researched on basis of inverse operation of spatial direction relation between two points.And the relation between two objects that had common regions was put stress on.The results were presented and tested finally.
