To provide an aerial photographing system of a farm field capable of reducing the reshooting of an image or the like by appropriately evaluating an image obtained by imaging a farm field.SOLUTION: An aerial photographing system of a farm field comprises: an imaging device 30e provided at a multicopter 30 for imaging a farm field; an illuminance detection device 42 for detecting an illuminance at least during imaging by the imaging device; and an imaging evaluation part 18 for evaluating imaging by the imaging device on the basis of the illuminance during imaging. The aerial photographing system of the farm field comprises a display device 19 for displaying evaluation by the imaging evaluation part 18. The aerial photographing system of the farm field comprises an inclination detection device 44 for detecting an inclination of the multicopter 30. The imaging evaluation part 18 evaluates imaging by the imaging device on the basis of the inclination detected by the inclination detection device 44 and the illuminance.SELECTED DRAWING: Figure 1
