| Abstract: | Through constructing the surface model of earth-rockfill dam with the 3-D dam surface construction algorithm based on spherical projection， an accurate 3-D surface model of earth-rockfill dam is reconstructed herein， and then by taking the first phase data of it as the reference， the point cloud data collected from various periods are applied to make a comparative analysis with those from the reference model for obtaining the dam deformation information. On the basis of the relevant experiment， it is demonstrated that this method is feasible and practicable. |
