Application of Unmanned Aerial Vehicle Image-free Photogrammetry Technology in Land Reclamation Resurvey and Rectification
With the rapid economic growth of our country,the problem of land and ecological environment damage is increasingly promi-nent,land reclamation and ecological recovery has been urgent. How to quickly and accurately complete the land reclamation mapping work is also increasingly critical. In order to obtain the 3D geographic data of reclamation area quickly and improve the measuring efficiency,this pa-per analyzes the accuracy of image-free photogrammetry based on PPK and RTK fusion difference technology. Taking Bengbu as an example,this paper introduces the application process of unmanned aerial vehicle ( UAV-RRB-photogrammetry technology in the project Landl Recla-mation Survey and rectification and investigation of illegal problems in the city.
