基于交集成分细分的面/面目标拓扑关系扩展模型
Extended models of area/area object topological relations based on intersection component details
由于四交、九交拓扑关系模型未对空间目标的相交细节进行深入分析和详细表达，导致其对面/面目标基本拓扑关系复杂情形的区分能力不足。为此，以四交模型和九交模型为基础，引入空间目标之间交点个数、交线条数、节点贡献值等定量、半定量化元素，扩展其表达矩阵中的交集非空元素，构建基于空间目标交集成分细分的面/面目标拓扑关系扩展模型。剖析了面/面目标之间拓扑相接、拓扑相交和拓扑覆盖3类基本关系的多个复杂情形，分析了基于交集成分细分的拓扑关系模型扩展方法及对复杂拓扑关系分析的计算过程。最后，利用实例分析验证了扩展模型的有效性及优势。结果表明：扩展模型对面/面目标之间基本拓扑关系复杂情形的细节表达得更加准确、直观，同时也增强了拓扑关系模型的定量化、半定量化表达能力。
Because the four-intersection and nine-intersection to pological relation models fail to analyze and express the inter section details of spatial objects in depth,the irability to distinguish the complex cases of the basic topological relations of the area/area objects is insufficient.Therefore,based on the 4-intersection model and the 9-intersection model,quantitative/semi-quantitative elements such as the number of the intersection points,the number of intersection lines and the contribution value of nodes were introduced to extend the inter-sectionnon-empty elements in the expression matrix,and extended models of area/area object topological relations based on the intersection component details of spatial targets were constructed.This paper analyzed several complex cases of three basic relations about area/ area objects,such as topological connection,topological intersection and topological coverage,meanwhile it explored the extension method of topological relation models based on the intersection component details and the calculation process about complex topological relation analysis. Finally,the validity and advantage of the extended models were verified by an example analysis.The results show that the details of the complex cases of the basic topological relations between the area/area objects are expressed more accurately and intuitively by the extended models.Moreover,the ability of the quantitative/semi-quantitative expression of the topological relation models is also enhanced.
