| 摘 要： | 空间区域拓扑关系建模是空间推理、地理信息系统(GIS)和计算机视觉等领域一个非常重要的主题，模糊区域的拓扑关系建模正日益受到相关领域研究者的重视，在分析现有模型的基础上，提出了一种模糊区域的拓扑关系模型，该模型利用模糊集来表示模糊区域，通过三个谓词的真值来判断区域间的拓扑关系，将分明区域作为特例统一处理，根据谓词的多种真值能够实现多层次上的拓扑关系分析．

| Abstract: | The modeling of topological relations between spatial regions is an important topic in spatial reasoning, geographic information systems (GIS) and computer vision. The modeling of topological relations between fuzzy regions is getting more imperative and thus has attracted plenty of attentions from researchers. A topological relations model is proposed based on existing models between fuzzy regions. The model represents fuzzy regions as fuzzy sets and determines the topological relation with the values of three predications. It can deal with crisp regions as a specific case and analyze topological relations on multiple levels according to the values of the predications. |
