摘　　要：利用倾斜摄影测量创建实景三维模型的技术已日趋成熟,但无法应用于地下空间,如地铁站的三维建模。本文利用三维激光扫描仪获取地铁站高精度的三维激光点云数据,在3ds Max软件中建模,获得地铁站精细化的实景三维模型,并检核模型的精度。试验证明,该方法建立的三维模型既能保证精度,也能达到逼真、美观的三维效果,能够助力地下空间三维建模技术的发展。The technique of using oblique photogrammetry to create three-dimensional model of real scene is becoming more and more mature,but it can not be applied to underground space,such as subway station.In this paper,the high-precision 3D laser point cloud data of subway station are obtained by using 3D laser scanner,and the real scene 3D model of subway station is obtained by using 3ds Max,and check the accuracy of the model.The experiment shows that the 3D model can not only ensure the precision,but also achieve the realistic and beautiful 3D effect,which can help the development of 3D modeling technology in underground space.
