Description

  The present invention relates to an aerial photographing apparatus capable of photographing a target place from above using a balloon.

  Conventionally, aerial photography has been dependent on, for example, a Cessna machine, but due to the high cost, it was difficult to obtain the desired image immediately. In addition, aerial photography with a radio control helicopter is also used, but skill is required for maneuvering and there is a risk of crash. On the other hand, aerial photography using a balloon using helium gas has a high degree of freedom of photography, and can obtain images in real time at low cost, and even if it falls, the possibility of an accident is low Is generally used. This aerial photography device using a balloon is a device in which a camera is attached to a balloon and floats in the air so that a target location can be photographed. The shape extended in the direction is used (for example, refer to Patent Document 1).

  However, since the wind is often blowing in the sky, there is a problem that when the balloon is made into a spherical shape, it is easy to be blown by the wind, and shooting is not possible if a little strong wind is blowing. Also, when the balloon is extended in one direction, it is strong against the wind in the extension direction but weak against the wind in the lateral direction, so if the wind is blowing a little, move it to the target location. There was a problem that it was difficult to achieve the desired shooting.

  The present invention has been made based on such a problem, and an object thereof is to provide an aerial photographing apparatus that can improve wind resistance and can be easily moved to a target place.

  An aerial photographing apparatus of the present invention is formed in a spheroid shape, and a ratio of a length in a minor axis direction to a length in a minor axis direction is in a range of 0.55 or more and 0.65 or less. A radio control helicopter attached, an imaging device attached to the radio control helicopter and operated by the radio control, and a tether for tethering the balloon to the ground are provided.

  According to the aerial photographing apparatus of the present invention, since the balloon has a spheroid shape, the ratio of the length in the minor axis direction to the length in the major axis direction is set to 0.55 or more and 0.65 or less. Wind resistance in the direction can be improved. Also, since a radio control helicopter is attached to the balloon, it can be easily moved to the desired location during aerial photography. Further, since the balloon and the radio control helicopter are used, even if the battery of the radio control helicopter runs out, the balloon can be lowered slowly.

It is a figure showing the structure of the aerial imaging device which concerns on one embodiment of this invention.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows a configuration of an aerial imaging apparatus 10 according to an embodiment of the present invention. The aerial imaging device 10 includes, for example, a balloon 11, a radio control helicopter 12 attached to the balloon 11, and an imaging device 13.

  The balloon 11 is formed in a spheroid shape and is filled with helium gas. The ratio L2 / L1 of the length L2 in the minor axis direction to the length L1 in the major axis direction of the balloon 11 is in the range of 0.55 or more and 0.65 or less, and is 0.58 or more and 0.62 or less. It is more preferable if it is within the range. If the ratio L2 / L1 of the length L2 in the short axis direction to the length L1 in the long axis direction is larger than 0.65, the wind becomes difficult to separate because it is close to a sphere, and it is susceptible to wind resistance. This is because the performance is lowered. Further, if the ratio L2 / L1 of the length L2 in the minor axis direction to the length L1 in the major axis direction is smaller than 0.55, the thickness is reduced and the buoyancy is reduced. With such a configuration, the conventional balloon can only take aerial photography up to a wind speed of about 2 m, whereas it can take aerial photography up to a wind speed of about 4 m.

  In the balloon 11, for example, one or a plurality of ring-shaped locking tools 14 are disposed on the lower side with the major axis direction being horizontal and the minor axis direction being vertical. For example, one end of a suspension rope 15 is attached to the locking tool 14, and the other end of the suspension rope 15 is attached to the radio control helicopter 12. Thereby, the balloon 11 and the radio control helicopter 12 are connected by the suspension rope 15, and the balloon 11 floats in the air with the major axis direction being horizontal and the minor axis direction being vertical. For example, the suspension cord 15 is preferably configured by covering a wire with a tube, and the tube is preferably made of vinyl. This is because it can withstand shaking and play a gyroscopic role.

  The radio control helicopter 12 is for freely moving the balloon 11 and the imaging device 13 to a desired location during aerial photography. The radio control helicopter 12 includes, for example, a battery and is configured to be driven by the battery. In addition, the radio control helicopter 12 is configured to be operated by radio.

  The imaging device 13 is attached to the radio control helicopter 12 and configured to be operated by radio control, that is, by radio. Examples of the imaging device 13 include a camera and a video, which are configured to be driven by power supplied from a battery built in the radio-controlled helicopter 12. Thus, weight reduction is achieved by making the power supply of the radio controlled helicopter 12 and the imaging device 13 common.

  The aerial imaging apparatus 10 includes a tether 16 for tethering the balloon 11 to the ground. One end of the tether 16 is attached to, for example, the radio control helicopter 12 or the imaging device 13, and the other end of the tether 16 is wound around a winding drum 17 made of a reel or the like. Thereby, if the tether 16 is rewound, the balloon 11 will rise, and conversely, if the tether 16 is wound up, the balloon 11 will descend. Further, since the mooring line 16 is attached to the radio controlled helicopter 12, the mooring line 16 is moved outside the imaging range of the imaging device 13 by moving the radio controlled helicopter 12, so that the mooring line 16 is not reflected in the image. Be able to.

  This aerial imaging apparatus 10 can be used as follows, for example. First, for example, the balloon 11 is filled with helium gas, and the balloon 11 is floated in the air. Next, the tether 16 is rewound, the balloon 11 is raised, the radio control helicopter 12 is operated by radio, and the balloon 11 and the imaging device 13 are moved to a desired desired location. Thus, in this aerial imaging device 10, since the radio control helicopter 12 is used, it can be easily moved to a desired place. Further, in this aerial imaging device 10, since the shape of the balloon 11 is a spheroid, and the ratio L2 / L1 of the length L2 in the minor axis direction to the length L1 in the major axis direction is within a predetermined range, Even when a wind with a wind speed of about 4 m is blowing, the balloon 11 can be lifted and moved.

  Subsequently, an image is picked up by operating the imaging device 13 with a radio control. At that time, it is preferable that the radio controlled helicopter 12 is operated so that the tether 16 is adjusted to a position that does not fall within the imaging range of the imaging device 13. When imaging is completed, the radio controlled helicopter 12 is operated by radio and returned to the vicinity of the operator. After that, the tether 16 is wound up and the balloon 11 is lowered. In this aerial imaging apparatus 10, since the balloon 11 and the radio control helicopter 12 are used, even if the battery of the radio control helicopter 12 is exhausted or misoperated, the balloon 11 can be lowered slowly.

  Thus, according to the present embodiment, the balloon 11 has a spheroid shape, and the ratio L2 / L1 of the length L2 in the minor axis direction to the length L1 in the major axis direction is set to 0.55 or more and 0.65 or less. Since it did in this way, the wind resistance in all the directions can be improved. Moreover, since the radio control helicopter 12 is attached to the balloon 11, it can be easily moved to a desired place during aerial photography. Furthermore, since the balloon 11 and the radio control helicopter 12 are used, even if the battery of the radio control helicopter 12 runs out, the balloon 11 can be gently lowered.

  The present invention has been described with reference to the embodiment. However, the present invention is not limited to the above embodiment, and various modifications can be made. For example, in the above embodiment, each component has been specifically described. However, not all the components may be provided, and other components may be provided. Each component may have other configurations.

  Can be used for aerial photography.
