| 摘 要： | 针对运动轨迹等有向线对象的特点,提出了细节拓扑关系模型,以解决现有模型不能区分复杂细节的问题。首先基于空间推理中4交模型的方法,定义了DLO矩阵。进而根据交分量的类型,对DLO进行细化,给出空间语义更丰富的DDLO模型。对比分析显示,与HBT等现有经典模型相比,DDLO模型能够精确描述有向线对象多次相交的细节,能区分相交与相切,而HBT模型只能分辨固定的68种简单关系。 |

| Abstract: | According to the characteristics of directed line objects,such as track,a detailed topological relation model is proposed,thus the complex details can be captured.First,DLO matrix is defined based on the 4-intersection method of spatial reasoning.Then,by apply the intersection types to DLO,the DDLO model with rich spatial semantics is obtained.Finally,the analysis and comparison with classical models(HBT etc.) show that DDLO can precisely describe the detailed intersection of directed line objects and disti... |
