ABSTRACT: Traditional topographic map surveying typically uses total stations or RTK, which are complex to operate and time-consuming for data collection. Although traditional photogrammetry and spaceborne remote sensing can compensate for the shortcomings of traditional topographic map surveying, they have drawbacks such as untimely information acquisition, insufficient processing accuracy, significant vulnerability to climate, and high implementation costs. UAV oblique photogrammetry can both improve surveying speed and obtain precise 3D information of the survey area. With the gradual maturity of UAV close-range photogrammetry technology, it has been widely applied in 3D modeling of digital cities. Using UAV close-range photogrammetry technology to create real-scene 3D models has become a trend.
