The invention discloses an unmanned-aerial-vehicle patrol picture classification method and system. The method includes: acquiring camera location information in a picture shot when an unmanned-aerial-vehicle patrols; acquiring pole tower location information of pole towers in an equipment machine account; and calculating and determining a photographed target pole tower in the camera picture according to the camera location information and the pole tower location information. The system includes: a photograph information extraction unit, which is used for acquiring the camera location information in the picture shot when the unmanned-aerial-vehicle patrols; a pole tower information extraction unit, which is used for acquiring the pole tower location information of the pole towers in the equipment machine account; and a picture classification unit, which is used for calculating and determining the photographed target pole tower in the camera picture according to the camera location information and the pole tower location information. According to the method and the system, automatic picture classification work can be completed, massive work of manually arranging pictures can be reduced, work efficiency can be improved, and classification accuracy can be improved.
