【Abstract】 In view of the problems in the integrity and accuracy of the external fine modeling of complex stadium,this paper proposes a high-precision modeling method which integrates ground control,ground laser scanning and UAV modeling control. Firstly,a highprecision integrated coordinate system of control,scanning and UAV in the area is established by using special signs. Secondly,the whole adjustment and registration of the area is carried out by combining the control coordinates of the multi station laser scanning point cloud on the ground to generate the high-precision ground point cloud model under the integrated coordinate system. Thirdly,the highprecision top data under the integrated coordinate system is generated by using the UAV data and control points. Finally,fusion of two kinds of data to generate a complete,high-precision and fine model of the object. The experiment shows that the whole adjustment method can achieve high-precision registration of multi-site cloud,and the integrated control can achieve high-precision fusion of heterogeneous data,which solves the problem of high-precision modeling of complex building objects,and has great practical value.更多还原
