摘要: 本文利用三维激光扫描技术,非接触式获取高速公路监测区域内三维点云数据,利用三维点云面与面的差异比对方式计算出不同周期断路面的变形差异值,将计算结果汇总并以直观性色带图形成三维数据成果图与最终报告。实践结果表明,三维激光扫描仪测得的高速公路路面数据精度、测量效率均比较高,可满足高速公路路面监测的要求,为快速、高效地进行高速公路路面变形监测提供了技术支持。

Abstract: Use 3D laser scanning technology to obtain 3D point cloud data in the highway monitoring area in a non-contact manner in this paper. Use the difference comparison method of 3D point cloud between the surface to calculate the deformation difference value of different periods of broken roads. The intuitive color band diagram forms a three-dimensional data result diagram and final report. The results show that the accuracy and measurement efficiency of highway pavement data measured by the three-dimensional laser scanner are relatively high, which can meet the requirements of highway pavement monitoring and provide technical support for fast and efficient highway pavement deformation monitoring.

Key words: 3D laser scanning technology, non-contact, point cloud data, deformation monitoring
