摘要
重点研究了三维空间中拓扑关系和方向关系间的混合空间关系推理。用Allen区间关系对描述基于投影的空间划分方法得到的方向区域和用九交矩阵描述的拓扑关系,用定义法研究混合空间关系推理,推理结果用组合推理表表示。
Spatial relationship reasoning is an importance topic in the spatial relation studies. The mixed spatial relation qualitative reasoning between topological relation and directional relation in three dimensional space is studies in the paper. The directional regions based on the projection system and the topological relation based on the nine intersection matrix model are described with Alien＇s interval relation pairs. The presented method is used to make the mixed spatial reasoning between topological relation and directional relation, and reasoning results were shown by the composition tables.
