摘　　要：城市三维模型的建立能够全方位并直观地给人们提供有关城市的各种具有真实感的场景信息,较之平面二维数据具有更多的优越性。新一代海量影像处理系统"像素工厂"可以生产高精度的DSM和TDOM,为数字城市三维建模提供更为精确的基础数据,本文主要研究了基于DSM和TDOM的城市三维模型构建方法。The establishment of city in three-dimensional model can widely and intuitively provide people with a variety of realistic scenarios information related to the city,which has more advantages compared with two-dimensional data.＂Pixel factory＂ is the new generation massive image processing system,which can produce high-precision DSM and TDOM and provide the more accurate baseline data for digital city three-dimensional modeling.The major research of paper is the approach of building city three-dimensional model based on DSM and TDOM.
