| 摘 要： | 方向关系推理是定性空间推理领域的一项重要的研究内容，得到了国内外许多学者的关注，其中，主方向关系的合成又是方向关系推理的基石。本文以Goyal和Egenhofer提出的“井”方向关系模型为基础，考虑了关系合成中的两种情况，即基于一致性的合成（Consistency-based Composition）与实体论合成（Existential Composition），给出了一种基于一致性的关系合成的新方法，同时从理论上证明了该方法的正确性。

| Abstract: | Reasoning on direction relation is most important to research in the field of qualitative spatial reasoning,and has received a lot ofattention ofresearehers home and abroad.Ofthese,composition of cardinal direction relation is the foundation of reasoning on direction relation.Based on the direction model presented by Goyal and Egenhofer,two cases,consistency-based and existential composition,are considered in this paper.A new solution on consistency-based composition is given,and it's correctness is proved formally. |
