In order to explore the development potential of UAV oblique photogrammetry technology and give full play to the application value of real scene 3D model,multi-rotor UAV is used to carry three lens and five lens cameras respectively,and take a chemical park and key scenic spots in Zhuhai as the monitoring area to automatically produce real scene 3D model;Aiming at the problems of cavities,suspended solids,water surface holes and road unevenness in the original model,this paper establishes a set of refined model construction process,which plays an important role in improving the quality of UAV oblique photography 3D model and the subsequent application of the model.
