Application of 3D laser scanning technology in contactless deformation monitoring for expressway operation

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.
