Description

Detailed Description of the Invention

The present invention is applied to disaster investigation, road design,
The present invention relates to a method of shooting a target subject from the air using a remote-controlled aircraft according to various uses such as advertising, and more specifically, relates to an aerial shooting method using a TV monitor or the like while reducing the oscillation of the aircraft after takeoff and landing. It is a thing.

[0002]

2. Description of the Related Art Conventionally, various aerial photographing methods of this type have been proposed. However, in such a conventional example, manned flight causes high cost, and restrictions on airspace, terrain, etc. Had the problem of. As a solution to this problem, there is known one using a balloon (for example, JP-A-60-86531 and JP-A-60-53942).
Reference). In addition, an aerial photographing method using a remote-controlled helicopter, which does not rely on a balloon, has also been proposed (see, for example, Japanese Patent Publication No. 3-8320).

[0003]

In the former one of the conventional aerial photographing methods, the balloon oscillates due to the wind, and the camera also oscillates accordingly, and it takes time to stand still, which causes a problem in photographing efficiency. It is caused by the weight of the support member, the suspension member, and the support frame that are suspended to prevent rocking, but the structure is complicated and high accuracy is required, resulting in high cost. , There was a problem that it was difficult to respond immediately to changes in airspace.

Further, in the latter case, although it is possible to immediately respond to a change in location or air space, since the camera shake is absorbed,
The balance mechanism is arranged so that the balance bars are arranged at the top and bottom of the front and rear sides to elastically hold it using a piano wire, and it is lightweight and has a simple structure, but it is not enough to prevent swinging, and even during shooting. Since the camera box is fixed at the center position of the horizontal rod, it is not easy to change the camera angle.
It also had some uncertainties.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is, in a method of photographing an object from the air by a remote control aircraft, shaking the aircraft after takeoff and landing. An object of the present invention is to provide a photographing method in which the movement of the camera box, that is, the swing of the camera box is reduced, while the monitor is used to accurately capture the subject and reduce the cost of aerial photography.

Subject by communication of 28
The camera can be photographed at a fixed height position.

[0008]

First, at the destination, the altitude of the remote-controlled aircraft is sequentially increased by the remote-control operation (shown in FIG. 4), but when the position of the subject is restricted by the ground type or the air space, that is, the subject is adjacent to the mountain. When it is not located in a plane (shown in FIG. 3), the remote-controlled aircraft is directed in the direction opposite to the shooting method in the normal state and raised to a certain angular position height. At this time, although it is flying at the optimal climb angle, the resolution of the subject, the aperture of the camera, etc. are connected to the monitor lens tube terminal provided in the camera box and the antenna of the transmitter attached and the transmission set on the ground. The image is received on the monitor TV by communication with the machine antenna, and it is performed by confirming this.

In the camera box, the elastic member is also sandwiched by the vibration prevention plate so as to be sandwiched, and the shock absorber and the spring are connected to the upper prevention plate, so that the shocks during takeoff and landing are sufficiently absorbed, but the lower prevention plate is absorbed. The horizontal rod attached to the and the horizontal frame that slides left and right through the long holes provided at both ends of the horizontal rod and the bracket make the tilt angle of the camera firmly fixed to the left and right. After checking the image, when it is dropped to the ground, adjustment is made to obtain the optimum image.
