Aerial photogrammetry and aerial photogrammetric system

摘要

Aerial photogrammetry is provided by using two or more flying vehicles, each equipped with a GPS device and an image pickup unit. This method comprises setting up two or more photographing points and setting up a photographing point area, respectively, with each of the photographing points as the center, measuring a position of the flying vehicle by the GPS device, a step where each of the flying vehicle reaches each corresponding photographing point area and maintains the position of the photographing point area, acquiring a time when the flying vehicle finally reaches the photographing point area, setting up a shutter timing time after a predetermined time from the moment when the flying vehicle has finally reached the photographing point area, and taking aerial photographs by the two or more flying vehicles at the shutter timing time.
