城市地下空间资源质量评估基本单元体的研究

On Cell Cube for Quality Evaluation of Urban Underground Space Resource

  • 摘要: 提出了基于Grid+Voxel的基本单元体划分方法及不同类型属性信息提取的量化模型,有效地解决了地下空间资源质量评估最小近似均质体的3D剖分,及基于基本单元体不同类型的属性信息定量提取问题,修正了传统的以地面为参照的2D平面单元划分方法,是城市地下空间资源质量评估基本分析单元划分的一种有效的新方法。

     

    Abstract: The division method for cell cube is put forward based on Grid + Voxel.Further,the attribute of cell cube is analyzed,and quantitative models for attribute information extraction are also built.So the problem on cell cube is resolved,which includes the division for basic approximate homogenic three-dimensional spatial cell cube and the quantitative extraction for corresponding attribute information.Taking the central business district(CBD) of Beijing as an application case,the cell cube and the visualization result for underground space resource quality evaluation are showed.
