摘要

针对方向关系界定的不确定性

提出基于Vague集的不确定区域方向关系模型

并利用Vague集方向关系矩阵分析不确定空间对象的方向关系隶属程度.讨论了空间对象与其MBR间的方向谓词映射关系

给出了边界不确定对象之间的方向查询实例及算法.结果表明

用Vague集来表示不确定性区域能够体现出空间对象与方向片相交的最大(最小)程度

比用模糊集更确切

不确定查询更符合人类思维的心理特征.

Abstract

The authors discuss the uncertainty in defining direction relationships

and propose the uncertain direction of the relational model of Vague sets.Using the direction of the relationship between Vague sets matrix

we also analyze the uncertainty attached to spatial objects with the direction of the relationship between the degrees.Then the paper discusses the spatial object and its MBR mapping relations between the directions of the predicate

and puts forward the boundary between the uncertain direction of th...
