| Abstract: | Digital city is the inevitable outcome of the development of information age, Urban modeling is the important part of the digital city. Space data acquisition is the city of the most critical part of modeling. But the current technology remains low, the 3D-data acquisition is still difficult in china. This paper discusses the methods used for collecting and updating 3D data in city. And the methods of the photography measurement and 3D-laser scanning are mainly discussed. |
