Camera for photogrammetry and aerial photographic device
First Claim
1. An aerial photographing device, comprising a flying vehicle having a main frame, and a shaft passing through an opening in said main frame of the flying vehicle, tiltably supported in two perpendicular directions via a gimbal disposed on a flange surrounding the opening and extending in up-to-bottom direction, a GPS device having a GPS antenna installed on an upper end of said shaft, and a photographic device main unit installed on a lower end of said shaft, wherein optical axis of said photographic device main unit is designed so as to direct in vertical and downward direction due to gravitational force applied on said photographic device main unit, said photographic device main unit has an image pickup unit installed in a known relation with said GPS antenna and a control device for controlling image pickup of said image pickup unit, and said control device controls said image pickup unit so that still image is acquired by the image pickup unit, and an image pickup position at the time of image pickup is obtained by said GPS device, wherein damper springs are stretched between the shaft and the body of the flying vehicle, such that tensile force between the shaft and the main frame allows the shaft to maintain its vertical condition.
