Abstract：Unmanned Aerial Vehicle(UAV)oblique photography technology is a rapidly developing new technique that has been increasingly applied across various industries.By processing and modeling the acquired data,high-quality,high-precision 3D real-scene models can be created quickly and effectively.Traditional manual surveying methods are time-consuming,labor-intensive,and costly.In contrast,UAV oblique photography technology offers advantages such as flexibility,strong timeliness,and the ability to improve image quality to some extent.This technology has achieved remarkable results in applications such as water conservancy construction and the delineation of protected areas.In this study,a portion of the Longzi Lake Campus of North China University of Water Resources and Electric Power was selected as the research area.A DJI drone was used to capture aerial images of the study area,and ContextCapture software was employed to construct a 3D real-scene model of the experimental zone.Subsequently,the accuracy of the model was enhanced by incorporating coordinates of ground control points obtained through field measurements.
