摘要/Abstract

摘要： OPRA_m是研究二维相对方位关系的经典模型之一,但解决实际问题通常需要考虑多维空间中的方位关系,为了表达三维空间中点对象间相对方位关系,将xoy平面相对方位和z轴相对方位相结合;通过定义与之相对应的能表达相对方位信息的两个相对角得到3DOPRA_m模型,并给出其在多粒度下的形式化定义及逆关系。给出了3DOPRA_m模型的概念邻域。最后用其基于动作的邻域关系描述汽车导航问题。结果表明,本文提出的模型能够细致、合理地表达三维空间中点对象间的相对方位关系,在实际中有广泛的应用前景。

Abstract: OPRA_m is the classical model in the study of two-dimensional direction relationship. However, to solve practical problems, the multi-directional space relationship should be considered. In order to express the relative direction in three-dimensional space, the relative direction of the xoy plane is combined with the relative direction of the z-axis. A three-dimensional relative direction model, 3DOPRA_m, is proposed by extending the model OPRA_m for two-dimensional direction relationship, and two new relative angles are defined. Moreover, the formal definition of 3DOPRA_m multi-granularity, its reverse relationship and the conceptual neighborhood of 3DOPRA_m are given. Finally, the conceptual neighborhood based on the action of 3DOPRA_m model is applied to describe the car navigation problems. Results show that, compared with existing two-dimensional model, the proposed model is more expressive and can describe more relative directions in three-dimensional space, which has great potential for practical applications.
