摘　　要：城市三维可视化表达与应用已经成为"数字城市"建设中的重要内容,建筑物的三维模型重建对数字城市的建设具有重要意义。本文以某大楼为例,用全站仪进行特征数据采集,在AutoCAD中构建高精度线框模型,结合3DMax的高效模型创建功能,对其进行三维模型重建,而且所建模型都具有真实的三维坐标。结果表明此方法能够满足建筑物的精度要求,有助于数字城市的建设。Urban 3D visualization applications have become an important part in the construction of ＂digital city＂ , 3D model reconstruction of buildings is of great significance. This paper illustrates the 3D reconstruction of a building by using a total station to acquire characteristic data and combing AutoCAD to create high-precision line-frame model , and the model obtained has real three-dimensional coordinates. The results show that this method can meet the accuracy requirements of the building, and it can contribute to the construction of digital cities.
