虚拟空间模型是由空间对象及其之间的空间关系构成,它为虚拟场景的构建提供了重要的语义信息。然而,由于空间对象和空间关系本身的复杂性,构建的虚拟空间模型通常是不全面的、非具体的。针对这种问题,在充分研究本体以及UML的基础上,提出了利用本体标记虚拟空间对象及对象之间的空间关系,从而构建了虚拟空间本体。论文首先提出虚拟空间中方向关系的计算方法,然后使用UML描述虚拟空间本体的空间结构,并使用OCL描述虚拟空间本体中虚拟对象的约束信息。最后通过一个虚拟办公室的实例,证明了该方法的可行性以及有效性。
The virtual space model is composed of spatial objects and their spatial relationship, which provides important semantic information for the construction of virtual scenes. However, due to the complexity of the spatial objects and the spatial relations themselves, the constructed virtual spatial models are usually incomplete and unspecific. In order to solve this problem, on the basis of fully studying ontology and UML, this paper proposes to use ontology to mark the spatial relationship between objects and objects in virtual space, and to construct the ontology of virtual space. The dissertation first proposes the method of calculating the directional relationship in virtual space, then uses UML to describe the spatial structure of virtual space ontology, and uses OCL to describe the constraint information of virtual objects in virtual space. Finally, through an example of a virtual office, it proves the feasibility and effectiveness of the method.
