群组目标空间方向关系研究进展

The Modeling of Spatial Direction Relations between Object Groups

群组目标空间方向关系是空间方向关系的重要组成部分,对其相关概念、特点、影响因素及研究模型进行了阐述,探讨了已有的4种模型的基本思路及其优缺点,提出了群组目标空间方向关系研究的不足以及以后发展的方向。

The spatial direction relation between object groups is an important part of spatial direction relationship. The related concepts, characteristics, influencing factors and research models are represented, and the basic ideas and merits and demerits of the existing four models are discussed. At last, the research deficiency and the developing direction of the spatial direction relationships between object groups are proposed.
