Research on Oblique Photographic 3D City Modeling Based on Layered Display
In recent years,with the development of intelligent cities,3D spatial data has become a new and intui-tive way of data expression that is necessary for social development,and the traditional manual modeling method which is laborious,time-consuming and long-term and the traditional non-contact photogrammetry technology which only obtains modeling image data from the vertical direction can no longer meet the complex requirements of the 3D modeling of smart cities.The emergence of the oblique photogrammetry technology has overturned the limitations of the original modeling shooting angle,and provided an automatic,low-cost,high-efficiency and high-precision modeling process.Based on the oblique photogrammetry technology,this paper designs the process of 3D modeling data collection technology in a city in Jilin Province in detail,collects the oblique photographic 3D modeling data of the modeling area by the aircraft equipped with a five-len aerial camera and a fixed-wing UAV operating platform,and realizes automatic batch modeling and the monomerization of the 3D model by modeling software.
