基于格网点的三维激光扫描技术在边坡监测中的应用

Application of 3D laser scanning technology based on grid in slope monitoring

边坡监测是工程建设过程中的重要环节,传统监测方法需要布设点位配合全站仪、水准仪等设备进行监测,受制于点位布设困难及测量区域受限等因素,传统监测方法在边坡监测中难度较大,利用三维激光扫描仪对边坡监测区域进行扫描,通过建立格网监测点位,设置搜索范围,拟合格网点监测值,通过两期监测数据比较,验证了三维激光扫描技术在边坡监测中应用的可行性,为同类项目实施提供借鉴。

Slope monitoring is an important link in the process of engineering construction.Traditional monitoring methods need to set points to cooperate with total station,level and other equipment for monitoring.Subject to factors such as difficult point layout and limited measurement area,traditional monitoring methods are difficult in slope monitoring.In this paper,three-dimensional laser scanner was applied to scan the slope monitoring area,establish grid monitoring points and set the search range,fitting the monitoring values of grid monitoring points.Through the comparison of the monitoring data of two phases,the feasibility of the application of three-dimensional laser scanning technology in slope monitoring was verified,which could provide reference for the implementation of similar projects.
