YOU Hong-jian, LIU Tong, SU Lin, et al. Fast Acquiring Urban DSM Image and Displaying 3D Image[J]. Journal of Remote Sensing, 2001,(1):8-12. DOI: 10.11834/jrs.20010102.
urban digital surface models (DSM) are widely used in many fields. Airborne 3D imager which is developed by the Institute of Remote Sensing Applications
Chinese Academy of Sciences can acquire DSM in quasi-real-time without any ground control points. The data processing technology to acquire urban DSM by 3D imager is presented in this paper. How to display urban DSM which is different from natural surface in 3D is discussed in detail. An example of data processing and 3D displaying of urban DSM is given at the end. According to the fly test the efficiency of 3D imager is several times higher than that of traditional methods to acquire urban DSM
and the method to display urban DSM in 3D is feasible.
