Abstract: To remedy the deficiency of the 3DR34 relation model, the enhanced 3DR34 relation model is proposed. Based on the new model, a great of 3D direction relations can be presented and distinguished. To predict and analyze the dynamic direction relations, the dynamic adjacent relations of the enhanced 3DR34 model are studied. Application results show that the model can enhance the ability to handle the 3D direction relations of the computer.

摘要： 为了弥补3DR34关系模型在复杂的3D方向关系表示精度上的不足，研究提出了增强型3DR34关系模型，利用新的关系模型可表示和区分大量的3D方向关系。为了便于对动态方向关系的智能预测与分析，进一步对增强型3DR34关系模型的动态邻接关系进行了研究。该研究成果极大地增强了计算机对空间方向关系的分析和处理能力。
