Abstract
Nowadays, in urban area, the buildings are scanned for 3D reconstruction. However, it costs much money and causes dramatic computation. In order to deal with it, InSAR technique is one of the potential ways. In the paper, high revolution SAR data, TerraSAR-X data, are used for 3D reconstruction of clustered building in urban area. Without external DEM, the method based on time series of SAR data is proposed for accurate DEM. The effectiveness of the proposed way is tested by TerraSAR-X data in Xi'an China, which are acquired on June 10, July 2 and July 24, 2014 respectively.
