摘    要:空间区域的拓扑关系和方位关系是空间推理的重要研究内容,以往的工作集中在单一的空间方面, 这不能满足实际应用领域的需要.基于主方位模型给出了主方位关系的形式化定义,考虑到拓扑与方位间的相互依赖关系,提出了结合拓扑和方位的定性表示与推理算法,能够处理多方面空间信息,在空间数据库和机器人导航等领域具有实际应用价值.

关 键 词:定性空间推理  约束满足问题  拓扑  方位  结合  拓扑关系  定性空间  推理方法  Direction  Topology  Spatial  Reasoning  价值  机器人导航  空间数据库  空间信息  处理  推理算法  定性表示  相互依赖关系  形式化定义  位模型  应用  工作集  研究

Abstract:Topological relations and direction relations between spatial regions are two important research topics in spatial reasoning. Most previous spatial reasoning researches focused on single aspect. Those were inadequate for real world applications. Formal presentation of cardinal direction is defined based on cardinal direction relation matrix model proposed by goyal and egenhofer. The representation and reasoning technology which integrating topology and cardinal direction is proposed, and interdependencies between them is considered. It deals with more than just one spatial aspect, and is valuable in the fields such as spatial database and robot navigation.
Keywords:Qualitative Spatial Reasoning  CSP  Topology  Direction
