The invention provides an unmanned aerial vehicle aerial photography method for post-earthquake emergency, which comprises the following steps: acquiring seismic source parameters, simulating a three-dimensional co-seismic deformation field by adopting an okada model according to the seismic source parameters, and dividing disaster levels according to the three-dimensional co-seismic deformation field; carrying out superposition analysis on the three-dimensional seismic deformation field and vector diagrams of buildings and roads in a disaster area to obtain an aerial photography range; in combination with parameters of an unmanned aerial vehicle, performing air route layout on the aerial photography range, performing aerial photography on an area with the serious disaster grade preferentially, a planar ground object aerial photography method is adopted for a building area, and a strip-shaped ground object aerial photography method is adopted for a road area; after the air route is obtained, calculating the exposure point position of the camera according to the parameters of the camera carried by the unmanned aerial vehicle and the topographic data in the three-dimensional resonance deformation field; and enabling the unmanned aerial vehicle to fly along the air route, and shooting at the camera exposure point position by using the camera. The method can obviously improve the aerial photography efficiency of the unmanned aerial vehicle.
