Abstract: With the advancement of real scene 3D modeling in China, the reconstruction of city-level real scene 3D models has become a key focus of research. However, there are challenges in the process of oblique photogrammetric modeling for urban areas, such as large amounts of data processing, complicated and diverse terrains and occlusion of viewpoints leading to model deformation. To address these issues, this paper summarizes a complete technical workflow for city-level real scene 3D model reconstruction by fusing oblique aerial images and airborne LiDAR point clouds. The proposed workflow is validated using data from Zhongshan city, and the results demonstrate that this workflow can effectively improve the efficiency and quality of city-level real scene 3D model reconstruction.

Key words: oblique photogrammetry, city-level 3D model, aerial triangulation, airborne LiDAR
