| Abstract: | In order to solve the technical problem of point cloud acquisition by station scanner in plant reconstruction,this paper proposes three-dimensional point cloud fusion technology.The station scanner is used to collect the point cloud data of pier,beam,door and window of the plant,and the UAV tilt photography is used to obtain the building facade information.The two measurement results are fused to obtain the complete three-dimensional point cloud data of the plant.The experimental results show that the 3D point cloud fusion technology improves the integrity of the point cloud data,and makes the drawing of design drawings easier to interpret and the size more accurate. |
