摘要: 针对室内精细化管理的需求,提出了一种顾及精细层级的室内拓扑模型。该模型首先将室内空间构件分为“主体对象-连通对象-虚拟对象”三种类型;接着以主体对象为基准,在垂直方向上又将室内空间划分为“楼栋-楼层-房间-设备”4个级别,并抽象出虚拟对象实现对对象的二次划分;然后针对同级别对象和跨级别对象建立了拓扑组织规则;最后结合三维引擎Cesium.js对模型进行了管理可视化验证。结果表明,该数据模型能够有效地满足精细场景的数据管理需求。

Abstract: To meet the demand of refined management, a kind of fine-hierarchy-considered indoor topology models is proposed. First of all, the model classifies indoor components into three categories "main object-connecting object-virtual object". Based on main object, the model classifies indoor space into four levels of "building-floor-room-equipment" and abstract virtual object in order to re-divide object. Secondly, the model builds topological rules between main objects. Finally, the experiment of data management and isualization is conducted on the basis of Cesium.js. The result shows the mode is effective in terms of fine scene management.

Key words: indoor space, main object, fine, topology, levels
