| 摘 要： | 3D空间对象方位关系的表示和分析在空间数据库、地理信息系统、人工智能和机器人学等领域具有重要的意义。为了分析和处理复杂的3D空间对象的方位关系，讨论了3种3D空间对象方位关系的立体表示模型：3DR7模型、3DR27模型和3DR39模型，给出了方位关系的交集序列；研究了3D空间对象方位关系的动态邻接关系和处理方法；进一步给出了3D空间对象方位关系的双向映射模型。研究成果为3D空间对象方位关系在空间数据库和地理信息系统等领域的应用奠定了基础。

| Abstract: | Representation and analysis about the direction relations of the 3D spatial objects have important significance in the spatial database，geographic information system，artificial intelligence and the robotics.To analyse and deal with the complex direction of the 3D spatial objects，the three tridimensional representation models such as the 3DR7 model，the 3DR27 model and the 3DR39 model are given，and the intersection sequences are also proposed.Furthermore，the dynamic direction adjacent relations and the bidirectional association representation of the 3D spatial objects are also studied.The research results lay the foundations for the applications of the direction relations of the 3D spatial objects in the spatial database and the geographic information system. |
