摘要
本文分析了三维模型不同构建方式的优缺点,探讨了三维场景模型地理要素的取舍问题,以及利用DLG数据快速构建城市三维模型的方法,并对城市复杂结构地物的快速建模及与场景的融合也进行了研究。最后以赣州市老城区为例,进行了城市三维场景的快速构建,结果证实,DLG数据快速构建三维模型效率高,渲染速度快,成本低,精度相对高。
This paper analyzes the advantages and disadvantages of different 3D model construction methods, discusses the problem of the choice of Geographical elements of 3D scene model, and the method of rapid construction of 3D scene model by using DLG data, and the integration of modeling of urban complex structure and the 3D scenes are also studied. Finally, taking GANZHOU ancient city District as an example, we build a 3D city scene quickly. The results confirm that DLG data can quickly build 3D models with high efficiency, fast rendering speed, low cost and high accuracy.
