【摘要】 利用地下工程监测数据的空间特性,对离散监测点和等高线采样点进行混合建模,采用带约束条件的点缓冲及填充算法分析实现了地形图与地表常规形变监测数据的结合,并自编程序实现了地下工程多层空间(不规则三角形网面即TIN面片)的可视化,揭示地形图与地表常规离散点形变监测数据之间的关系和隐藏在相应数据背后的信息。同时,探讨了应用多层TIN面片和其他背景图层的混合空间3维建模。更多还原

【Abstract】 Based on the spatial characteristics of underground engineering monitoring data,this paper carried out the hybrid modeling for discrete monitoring points and contour sampling points.Using the algorithm of point buffering and filling with constraint condition,it realized the combination of topographic map and general deformation monitoring data on land surface,and realized the visualization of underground engineering multi-level space(irregular triangle network surface,TIN surface) by programming.It revealed the relationships between topographic map and general deformation monitoring data on land surface and the information behind the data.Meanwhile,it discussed the 3D hybrid spatial modeling using multi-level TIN surface and other background map.更多还原
