一种定量化表达的空间关系模型

A Quantified Model for Spatial Relationships

  • 摘要: 目前已有的空间关系模型(拓扑关系、方向关系以及度量关系)基本上是相对独立的,同时这些模型(度量关系除外)主要是定性的形式化描述,其表达精度还有待提高,因此有必要研究定量化的、组合表达的空间关系模型。提出了一种定量化表达的空间关系直方图模型,它能同时表征两个面目标之间的拓扑关系、方向关系以及度量关系,并可以定量化地分类(概率表征)空间关系类型。实验结果验证了该模型的有效性。

     

    Abstract: Existing spatial relationship models(topological,directional and metric relations) are generally separated from each other.Furthermore,these models are qualitative descriptions,with low precision.Thus,it is necessary to develop quantified and integrated spatial relationship model.This paper proposes a histogram to represent spatial relationships,the topological,directional,and metric relations between objects,and can quantitatively classify these spatial relationships.Experimental results illustrate the validity of this model.
