摘要: 目前很多现有应用系统采用的是方向关系和拓扑关系的独立描述模型,影响了空间推理和空间表达的精度。在分析了拓扑关系和方向关系模型的基础上,提出了一种基于Voronoi图的拓扑关系和方向关系的组合模型,使其能较全面地描述对象的空间关系。

关键词: Voronoi图, 拓扑关系, 方向关系, 空间关系, 组合模型

Abstract: At present, most current application systems use independent description model of direction relations and topologic relations, they influence the precision of spatial reasoning and spatial expression. The ultimate aim of this paper is to work out a combined model for topologic relations and direction relations based on Voronoi diagram, so that spatial relationship can be described more integrated.

Key words: Voronoi diagram, topologic relations, direction relations, spatial relationship, combined model
