基于VB与Matlab编程的边坡监测数据场可视化

实现监测数据场空间监测物理量的三维可视化显示是对边坡安全监测结果进行高效分析的方法之一。在Visual Basic中引入Matrix VB组件,通过编写Visual Basic程序并调用Matlab插值函数,对监测数据场的空间数据进行插值,再运用参数化建模方法和X3D虚拟语言技术,最终在Visual Basic平台下实现了监测物理量的三维显示。该方法集中了Matlab函数和Visual Basic各自的优点,有效解决了边坡监测区域监测点的插值问题。工程实例表明,应用该方法能实现边坡监测数据场的三维云图显示,可为边坡的安全监测结果处理提供理论依据。

Research on visualization of slope monitoring data field based on Matlab and VB hybrid programming

One of the efficient analysis methods for slope safety monitoring results is to achieve 3-d visualization of spatially monitored physical quantity in monitoring data field. Through introducing the MatrixVB component into Visual Basic, the spatial data of monitored data field was interpolated by programming Visual Basic program with calling Matlab interpolation functions, the 3-d visualization of monitoring physical quantity in the slope engineering is realized on the Visual Basic platform by using para-metric modeling method and X3D visual technology. This method combines the advantages of both Matlab interpolation functions and Visual Basic and can solve the interpolation problem of monitoring points in monitored slope area effectively. Taking one slope of a hydropower station for example, the 3-d nephogram of slope monitoring data field in the slope engineering is realized, which can provide theoretical basis for processing the safety monitoring results of slope engineering.
