Among the methods of shooting such aerial photographs, the manned aerial photographing method is to shoot a thing or a landscape by attaching a camera to a fuselage which a pilot directly operates, such as an airplane or a helicopter, And the camera can be directly corrected for the focus or angle while viewing the photographed image or the image being photographed, so that an object can be accurately photographed.

However, there is a problem that a photograph or an image photographed due to a camera shake due to a large vibration transmitted from an aircraft is not clear, and in particular, a vibration transmitted from an aircraft and a high altitude The vibration due to the external wind is transmitted to the camera.

In order to solve the above problems, there has been proposed a Korean conventional model registration No. 20-0282808 (2002.07.09.) "Aircraft Camera Mounting-Control System" (hereinafter referred to as "Prior Art 1") The above-described prior art 1 has a base plate, a support frame installed on the base plate, a camera left and right adjustment frame rotatably mounted on the upper part of the support frame, A camera tilting angle adjusting frame installed to be rotatable in a direction of the camera; a camera rolling angle adjusting frame installed inside the camera tilting angle adjusting frame so as to be rotatable in a rolling direction; A camera, a frame for adjusting the angle between the camera and the camera, and a camera tilting angle adjusting frame And a driving means for separately driving a camera rolling angle adjusting frame. The camera can be easily attached to a necessary portion such as a lower portion of a fuselage of a general airplane, and a pilot or a photographer can be controlled by a mechanical drive .

However, in the prior art 1, there is no means for absorbing or compensating for the vibration caused by the operation of the aircraft or the wind caused by the operation of the aircraft in a state where it is installed at a necessary place such as the lower part of the fuselage of the aircraft, there was.

In addition, Korean Patent Registration No. 10-1549380 (2015.08.27.)

So that the vibration absorbing part 70 absorbs the vibration transmitted from the airplane while supporting the body 10 from below, thereby minimizing the shaking of the body 10.

The air buffering means 80 is disposed inside the vibration absorbing portion 70 for canceling the vibration by discharging or sucking the air by the applied pressure. The air buffering means 80 includes a lower end 70b An air cap 81 connected to the air hole 811 and having an inlet communicating with the air hole 811 to discharge air or suck air and disposed inside the lower end of the vibration absorber 811; And a lower plate 84 disposed between the lower portion of the bracket 82 and the steel plate 74. The upper plate 83 is disposed between the upper portion of the bracket 82 and the second vibration- And an air sensor 85 provided on the outside of the air hole 811 and connected to the controller 90 to sense the amount and intensity of air entering and exiting through the air hole 811.

In contrast to the above-described vibration canceling means of the vibration absorbing portion 70, which is formed in the form of a gel, the rib 82 has the following differences.

First, in the case of the gel type, since the mass is not changed even under the pressure applied by the applied pressure, the load is applied downward, and the effect of canceling the vibration by the load may be reduced.

In the case of the ball bearings 82, when the pressure is applied, the air that has been stored is discharged to the outside, so that the weight is lightened and the load is not transmitted downward, thereby increasing the effect of canceling the vibration.

Further, when the applied pressure is released, since the load is supported in the expanded state by sucking the outside air, a higher buffering effect can be obtained.

The upper plate 83 and the lower plate 84 disposed on the upper and lower sides of the boom 82 respectively abut against the boom 82 and press the upper and lower plates 83 and 84, , Rubber, or silicone. However, it is preferable to use a soft silicone to minimize the damage to the ball by friction with the ball.

The air sensor 85 senses the amount and intensity of the air entering and exiting through the air hole 811 formed in the air cap 81 and transmits the detected amount and intensity to the controller 90. The amount and intensity The control unit 80 controls the horizontal rotation unit 20, the first rotation unit 30, the second rotation unit 40, the camera mount unit 50, and the driven rod 60 By displaying the controlled or sensed value to the user through the display, it is possible to induce an action such as stopping the shooting for a while if the sensed value exceeds or continuously occurs.
