What is the reason why the photos of UAV flight are expected to be reduced by half?

The reason why UAV flight is expected to reduce the number of photos by half: because cameras are generally hung in the bottom area of drones. For photographic imaging, the brightness of the scene only affects the exposure in the photo, and the important thing is the density difference between adjacent ground objects in the photo. If there is no density difference between images of ground objects, that is, there is no image contrast, it is impossible to distinguish ground objects from images. In addition to the characteristics of the scene itself, the factors that determine the image contrast mainly depend on the illumination difference between the sun part and the shadow part. If you choose to shoot in bad weather conditions, the picture quality will inevitably deteriorate.
