摘要
使用基于真实物体的方向关系模型,通过一系列的定义和定理,研究了一种基于真实物体的主方向关系的合成方法。在此基础上,提出了一种新的合成算法,该算法能够更有效地合成真实物体间更为复杂的主方向关系。
In this paper we used a model for real objects.By a series of definitions and lemmas,we studied a composition method which was applied to Cardinal direction relations based on real objects.According to our study,we put forward a new composition algorithm,which can be used to compose more complex cardinal direction relations of real objects availably.
