| 摘 要： | 智慧城市发展迅速，各地开展城市信息模型（CIM）基础平台建设的步伐不断加快，因而需要高效高质地构建不同类型场地的城市三维实景模型。本文针对传统航摄建模方法在突兀大高差场地三维模型重建中的不足，提出一种基于消费级无人机对突兀大高差场地进行阶梯式环绕拍摄航片并运用倾斜摄影技术对其进行三维建模的方法。同时运用该方法和传统模仿五镜头航摄的五架次航摄建模方法对桂林市南洲大桥进行对比试验。本文方法所重建的模型精度更高，效率得到提升，模型细节完整度更好。该方法能够高质高效地对突兀大高差场地进行三维重建，为CIM的创建提供更优的选择，促进智慧城市的发展。

| Abstract: | Smart cities are developing rapidly, and the pace of city information modeling (CIM) basic platform construction in various places is accelerating. Therefore, it is necessary to construct high-efficiency and high-quality three-dimensional city models of different types of sites. In view of the shortcomings of the traditional aerial photography modeling method in 3D model reconstruction of the abrupt large elevation difference site, this paper puts forward a method that uses consumer UAV to take aerial photos of the abrupt large elevation difference site in a ladder way, and uses the tilt photography technology to build the 3D model. At the same time, the comparative study of Guilin Nanzhou bridge is carried out by using this method and the traditional five shot aerial photography modeling method. The model reconstructed by this method has higher accuracy, improved efficiency, and better model details. This method is capable of high-quality and efficient three-dimensional reconstruction of the abrupt and large height difference site, which provides a better choice for the creation of CIM and promotes the development of smart cities. |
