摘要
针对文物建筑安全监测无接触这一特点,本文提出了一种无接触连续监测方法。首先根据监测对象的具体情况,建立了三维虚拟空间格网;然后根据空间格网与地面监测基准点严密的空间几何关系,建立了严密的测量基准网络,并利用高精度全站仪无接触式测量功能,实现了连续监测;最后,根据空间格网点和地面基准点之间严密的空间几何关系和每次测量的距离变化,确定空间格网点所对应的监测点的变化,并利用仿真和实际监测案例验证了本文方法的可行性与有效性,为文物监测提供了一种可行的监测方案。该方法也同样适用于其他类似建筑物、构筑物的连续监测。
Considering the non-contact characteristics of safety monitoring for cultural heritage buildings,this paper proposes a non-contact continuous monitoring method.The method first establishes a 3D virtual spatial grid according to the specific conditions of the monitoring object,then constructs a rigorous surveying reference network based on the strict spatial geometric relationships between the spatial grid and ground monitoring benchmarks.Continuous monitoring is achieved using the non-contact measurement function of high-precision total stations.The deformation of monitoring points corresponding to spatial grid nodes is determined through the rigorous spatial geometric relationships between spatial grid nodes and ground benchmarks,combined with distance changes from each measurement.Simulations and actual monitoring cases verify the feasibility and effectiveness of this method,which provides a practical monitoring solution for cultural heritage monitoring.This method is also applicable to continuous monitoring of other similar buildings and structures.
