摘要
地面沉降是一种潜在的地质灾害。随着城市化进程加快,地表形变监测有着重要意义。本文提出基于空天地多源监测技术构建地表形变分级监测体系,即“一级”基于遥感技术开展地表形变大范围普查、“二级”基于高精度实景三维模型与人工巡检进行安全排查、“三级”基于GNSS技术定点实时监测,实现地表形变空天地协同监测。并基于Cesium框架、Spring Boot框架、MySQL数据库构建三维可视化平台,实现多源形变监测数据三维动态展示。
Surface subsidence is a potential geological disaster.With the acceleration of urbanization,it is of great significance to carry out surface deformation monitoring.This paper proposes a hierarchical monitoring system for surface deformation based on multi-source monitoring technology of air-space and earth.The“first-level”is based on remote sensing technology to carry out a large-scale census of surface deformation,the“second-level”is based on high-precision real-world 3D models and manual inspections for safety inspection,and the“third level”is based on GNSS technology to conduct fixed-point real-time monitoring.The air-space and earth collaborative monitoring of surface deformation is thus realized.Meanwhile,a 3D visualization platform based on Cesium framework,Spring Boot framework and MySQL database to realize 3D dynamic display of multi-source deformation monitoring data.
