基于智能组件的虚拟场景建模

Virtual Scene Modeling Based on Intelligent Components

针对目前三维虚拟场景建模效率低下的问题,提出了基于智能组件的虚拟场景建模方法.将场景建模设计为三个层次:概念建模层、映射层和场景生成层.在概念层使用本体对场景对象及对象间的关系进行描述,构建场景对象本体知识库,与最底层的组件模型库一起构成智能组件库.通过中间的关联层对概念建模层及底层实现层进行映射.将该方法应用于三维组态软件场景组态过程,结果表明,使用该方法降低了三维组态软件建立三维监控场景的复杂度和难度,即使没有三维开发经验的自动化工程师也能很轻松地建立三维监控场景,便于三维组态软件的推广.

The virtual scene modeling method based on intelligent components is proposed aiming at the low efficiency of the present 3D virtual scene modeling methods. This method divides the scene modeling process into three layers： the conceptual modeling level, the mapping level, the scene generation level. In the conceptual layer, scene objects and the relations between objects is described using ontology, and scene objects knowledge base is built which constitutes the intelligent component base with the lowest level. This method maps between the conceptual modeling level and the lowest generation level by means of the intermediate link level. It is applied to the scene configuration process of the 3D configuration software, which can reduce the complexity and difficulty of creating 3D monitoring scene. This makes the automation engineers create 3D monitor scene so easily who has no 3D experience in the 3D development. And it is easy to implement.
