| Abstract: | In order to make up for the limitation that the traditional single point monitoring method based on GPS / GNSS can not reflect the overall deformation of tailings dam,a method for monitoring the surface deformation of tailings dam slope by using the unmanned aerial vehicle (UAV) combined with the existing displacement monitoring system was proposed.The single-lens light and small multi-rotor UAV and computer vision technology were used to collect the spatial three-dimensional geographic information of the tailings dam and reconstruct the tailings dam.Based on the displacement manual monitoring points (cement piles) set on the surface of dam slope,the multi-period point cloud data of tailings dam were registered,and the overall monitoring of the slope surface deformation was realized by calculating the distances of point cloud data of the tailings dam in different periods.The results showed that after the rainy season flushing,the local slope of a tailings dam in Shandong appeared the gully,slump,surface slip and other phenomena.This method can finely reflect the overall deformation and detailed change of the tailings dam slope,and it can provide reference for the development of the monitoring method of overall deformation of the tailings dam slope. |
