摘要:

针对传统9交模型对移动目标空间拓扑关系表达及量化描述的不足,基于格网化思想,提出了度量参数量化描述的方法。首先对移动目标和参考目标进行格网化,划分为固定大小的格网阵列;然后利用9交模型确定空间目标间拓扑关系的形式化描述;最后引入内部分量、边界分量、外部分量3种度量参数对移动目标空间拓扑关系进行度量化描述。试验证明,该方法计算简单、直观,能更加有效地度量移动目标间的拓扑关系。

Abstract:

Aiming at the deficiency of the traditional 9-intersection model to express and quantify the spatial topological relations of moving objects, a method of quantitative description of metric parameters is proposed based on the idea of gridization. Firstly, the moving object and the reference object are grid-processed and divided into fixed-size grid arrays; then the 9-intersection model is used to determine the formal description of the topological relations among the spatial objects; finally, the internal components, boundary components, and external components are introduced to describe the spatial topological relations of the moving objects. Experiments show that this method is simple and intuitive to calculate and can more effectively measure the topological relations between moving objects.

Key words: topological relations, gridization, 9-intersection model, metric parameters
