Abstract: Online direct detection of rolling deformation of fill material is an urgent problem to be solved in continuous compaction control. To study the deformation and its detection, this paper develops an online rolling deformation measurement method and constructs an application system based on the planar laser beam technology. The method uses laser ranging and key point location techniques to determine the relative deformation of rolling. The application system realizes the online direct detection of the relative deformation and obtains certain relative deformation rules for fill material rolling, which helps promote the practical application of intelligent construction technology in filling engineering.
