Ground surface deformation determination method and system based on unmanned aerial vehicle measurement

The invention discloses an unmanned aerial vehicle measurement-based earth surface deformation determination method and system. The system comprises an unmanned aerial vehicle, an inspection module, a base station, a write-in module, a resolving processing module, an acquisition module, a settlement map generation module and a mapping module. According to the embodiment of the invention, after the airborne POS data and the high-resolution image shot by the unmanned aerial vehicle are acquired through the unmanned aerial vehicle, the airborne POS data and the high-resolution image are checked; therefore, the unmanned aerial vehicle can shoot distortionless clear images in a normal pose, and the accuracy of orthoimages and digital surface models is improved; compared with a digital surface model or a digital elevation model, the method has the advantages that the earth surface crack observation effect is better by adopting the orthoimage, the crack is observed through the orthoimage, and the area where the crac
