A Quantified Model for Spatial Relationships

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.
