摘要
为了弥补3DR27关系模型的不足,详细研究了3DR34关系模型,给出了3DR34关系模型的形式化定义和方向关系交集序列;对3DR34方向关系模型的动态邻接关系进行了详细研究。研究成果增强了空间关系表示模型对3D空间对象方向关系的表示精度和处理能力。
To remedy the deficiency of the 3DR27 model,the 3DR34 direction relations model were studied in detail.The formal definition of the 3DR34 model and the intersection sequence were given.The dynamic direction adjacent relations were also studied..The research results enhanced the ability of the spatial relation models for the representation of the 3D direction relations.
