基于粗集的面实体动态空间方向关系研究

Dynamic spatial direction of spatial entities based on Rough set

为了研究不确定面实体与确定面实体之间的动态方向关系的性质,利用粗集理论和方向关系矩阵模型进行分析。分析结果表明:随着不确定面实体动态变化,其方向关系也是变化的。其结果更能表达客观的实际情况。因此,该成果可以完善方向关系研究的内容,具有一定的理论价值。

In order to study the nature of the relationship between the dynamic direction uncertain plane entity and determine surface entities,analysis was made by using rough set theory and direction relation matrix model. The results showed that with the dynamic changes of uncertain plane entity,the relationship is also changing its direction. The results are better able to express an objective reality. Thus,the results of research can improve the content of direction relations,which has some theoretical value.
