Japanese Patent Laid-Open No. 11-129996 JP 2000-326899 A

  By the way, in the conventional aerial photographing apparatus, since the camera is rotated by a rotation drive device composed of a drive motor and a gear mechanism, vibration is generated at the time of rotation, and about one rotation is required. There was a problem that it took about 20 seconds and the rotation speed was very slow. In particular, when performing 360-degree all-round shooting, if the camera is rotated and rotated while taking a picture, the shot image is easily blurred due to vibrations, and the rotating speed is slow. It is easy to move by the wind, and there is a problem that if the shooting position is moved, a positional shift occurs between the shooting frames.

  It is an object of the present invention to provide an aerial photographing apparatus that can solve the conventional problems.

  The present invention relates to a balloon that floats in the air, a fixed part that is suspended from the balloon and is non-rotatably connected to the balloon, and a movable part that is horizontally rotatable with respect to the fixed part. A support member suspended horizontally from the movable part of the joint member, a camera disposed on the support member, and an operation control means for controlling the operation of the camera. A thrust generated by the rotation of the propeller, the driving device provided on the support member at a position deviated from the center thereof, and a propeller that is pivotally supported on the rotation drive shaft of the drive motor. An aerial imaging apparatus comprising: a rotation drive device that horizontally rotates a support member by a remote control device; a remote control device that remotely controls the operation of the drive motor; and a tether that anchors the balloon to the ground. It is.

  Here, a digital camera and a digital video camera are preferably used as the camera. In the case of a digital camera, the operation control means of the camera can be composed of a wireless controller including a transmitter and a receiver. The operation of the camera is controlled by the receiver on the support member that receives the operation control signal transmitted from the ground by the transmitter of the wireless controller, and the captured image can be transferred to the ground by the wireless file transmitter. In the case of a digital video camera, the camera operation control means may be constituted by a remote control device that controls the operation of the camera on the ground, and a DV cable that connects the remote control device and the camera. Further, the remote control device for remotely controlling the operation of the drive motor can be constituted by a radio control transmitter on the ground side that transmits a control signal and a radio control receiver on a support member that receives the transmitted control signal. Further, a small and light brushless DC motor can be suitably used as the drive motor.

  In the aerial imaging device, a pair of drive motors of the rotation drive device are arranged on both the left and right sides of the support member, and the thrust generated by the rotation of the propeller supported by the rotation drive shafts of both drive motors is supported. A configuration is proposed in which the member is rotated in the opposite direction.

  Moreover, in such a configuration, a configuration is proposed in which the pair of left and right drive motors are disposed in protruding portions that protrude outward from the opposing edges of the support member.

  In addition, the joint member includes a rotation drive mechanism that rotationally drives the support member, and a remote rotation drive control device that remotely controls the operation of the rotation drive mechanism. A configuration is proposed in which the support member can be rotationally controlled by the drive control device.

  In addition, a plurality of drive motors having propellers pivotally supported on a rotation drive shaft are disposed at the periphery of the sub-support member stepped on the lower portion of the support member, and are supported by an outward blowing action by the rotation of each propeller. A configuration is proposed in which the member is stabilized.

  In the present invention, as described above, the drive motor is disposed at a position offset from the center of the support member suspended from the movable portion of the joint member that can be rotated horizontally. Since the support member is horizontally rotated by the thrust generated by the rotation of the propeller supported on the shaft, when the thrust generated by the rotation of the propeller acts as a rotational moment force on the support member, the support member is suspended. The movable portion of the joint member is horizontally rotated, and the support member is horizontally rotated through the horizontal rotation of the movable portion. For this reason, there is almost no vibration when the support member is horizontally rotated, and the support member can be rotated very smoothly, and the time required for one rotation is about 2 seconds. Can be speeded up. As a result, when 360-degree shooting is performed, even if the support member on which the camera is arranged is rotated in the horizontal direction and shooting is performed, vibration due to vibration does not occur, so the shot image may be blurred. In addition, by increasing the rotation speed, depending on the strength of the wind, if the wind is about 3 winds (less than 5.5 m / s), the movement of the floating balloon is affected by the wind. All-round photographing that is not received is possible, and no positional deviation occurs between the photographing frames.

  In the aerial imaging device, a pair of drive motors of the rotation drive device are arranged on both the left and right sides of the support member, and the thrust generated by the rotation of the propeller supported by the rotation drive shafts of both drive motors is supported. In the configuration in which the member is rotated in the opposite direction, the support member is moved in both the forward and reverse directions by selectively driving a pair of drive motors arranged on the left and right sides of the support member. It can be selectively rotated horizontally, and the photographing direction adjustment in which the lens of the camera is directed in the direction where the subject to be photographed is quickly performed.

  Further, in the configuration in which the pair of left and right drive motors are disposed in projecting portions that project outward from opposite edges of the support member, respectively, from the rotation center point of the support member Since the distance to the drive motor becomes longer and the rotational moment force due to the thrust can be increased, if the thrust is the same as compared to the case where the drive motor is arranged near the rotation center point, While the support member can be quickly rotated, if the rotation speed is the same, a smaller thrust may be used, so that power consumption can be suppressed.

  In addition, the joint member includes a rotation drive mechanism that rotationally drives the support member, and a remote rotation drive control device that remotely controls the operation of the rotation drive mechanism. In the configuration in which the rotation of the support member can be controlled by the drive control device, the rotation of the support member can be used to assist in adjusting the shooting direction in which the lens of the camera is directed in the direction of the subject to be shot. Fine adjustment can be easily performed.

  In addition, a plurality of drive motors having propellers pivotally supported on a rotation drive shaft are disposed at the periphery of the sub-support member stepped on the lower portion of the support member, and are supported by an outward blowing action by the rotation of each propeller. In the configuration in which the member is stabilized, the sub-support member is obtained by concentrating and balancing the rotational moment force generated by the outward blowing action by the rotation of each propeller at the rotation center point of the sub-support member. Is suppressed, and the support member to which the auxiliary support member is attached can be stabilized.

Hereinafter, a first embodiment of an aerial imaging apparatus according to the present invention will be described with reference to FIGS.
As shown in FIG. 1, the aerial photographing apparatus 1 includes a balloon 2 that floats in the air, a joint member 3 that is suspended from the balloon 2, and a support member 4 that is suspended below the joint member 3. A tether 5 for mooring the balloon 2 to the ground.

  The balloon 2 is formed in an airship shape with a width of about 2.5 m and a length of about 3.5 m, which is filled with helium, and is capable of lifting a weight of about 15 kg. The balloon 2 may have a substantially spherical shape with a diameter of about 2.5 m.

  The upper ends of a plurality of ropes 6 are attached to the left and right side surfaces of the balloon 2, and the lower ends of the ropes 6 are connected to the fixing portion 7 of the joint member 3. Here, as shown in FIG. 2, the joint member 3 includes a fixed portion 7 formed in a bottomed cylindrical shape, a thrust bearing 8 accommodated in the fixed portion 7, and a horizontal position with respect to the fixed portion 7. The movable part 9 provided so that rotation was possible was provided. The movable portion 9 includes a circular substrate portion 10 that is in contact with the upper portion of the thrust bearing 8, a shaft portion 12 that is vertically inserted so as to pass through the centers of the substrate portion 10 and the bottom plate portion 11 of the fixed portion 7, It consists of an annular locking part 13 formed at the lower end of the shaft part 12. The shaft portion 12 is inserted from below into through holes 60 and 61 formed in the bottom plate portion 11 and the substrate portion 10, and a retaining nut 14 is screwed to the upper projecting end of the shaft portion 12. It can be rotated only around the axis through the operation. In addition, a plurality of annular coupling portions 15 project from the outer peripheral surface of the fixed portion 7 at equal intervals in the circumferential direction, and by connecting the lower end of each of the strips 6 to each annular coupling portion 15, The fixing portion 7 can be connected to the balloon 2 so as not to rotate.

  As shown in FIG. 3, the support member 4 is formed in a flat rectangular plate shape, and is suspended horizontally on the movable portion 9 of the joint member 3 via a suspension frame 16. The suspension frame 16 has a gate-shaped main frame 17 having both lower ends fixed to the upper surface of the support member 4, one end fixed to the upper center of the main frame 17, and the other end fixed to the upper surface of the support member 4. The center of the upper portion of the main frame 17 is vertically aligned with the center of gravity of the support member 4 to which required equipment such as a camera 59 (see FIG. 4) described later is attached. Arranged. Further, as shown in FIG. 2, a connecting bolt 19 having an annular portion 20 at its upper end is attached to the center of the upper portion of the main frame 17, and the annular portion 20 of the connecting bolt 19 and the joint member 3 are connected. An annular locking portion 13 of the movable portion 9 is detachably connected via a carabiner type connecting fitting 21.

  Protruding portions 22, 22 having predetermined lengths are formed outwardly at opposite edges of the support member 4, respectively, and the protruding portions 22, 22 include a pair of left and right drive motors 23, 23 is arranged. As a result, the drive motors 23 are arranged at positions deviated from the center of the support member 4. Propellers 25 and 25 are pivotally supported on the rotational drive shafts 24 and 24 of the drive motors 23 and 23, respectively, and the support member 4 is movable by the thrust generated by the rotation of the propellers 25 and 25. The unit 9 (see FIG. 2) is horizontally rotated with the fulcrum as a fulcrum. Further, the mutual thrust generated by the rotation of the propellers 25 and 25 causes the support member 4 to rotate in the opposite direction. Thus, by selectively driving one of the drive motors 23, 23, the support member 4 is rotated by the thrust generated by the rotation of the propeller 25 that is pivotally supported by the rotation drive shaft 24 of the drive motor 23. A direction is selected. The drive motors 23 and 23 and the propellers 25 and 25 constitute a rotation drive device that horizontally rotates the support member 4. As the drive motors 23, 23, brushless motors that are small and light and have excellent durability can be suitably used. The support member 4, the suspension frame 16, and the projecting portions 22 and 22 may be made of a light material having a predetermined strength such as aluminum or hard synthetic resin. Among them, carbon fiber reinforced plastic is preferable. Can be used.

  The operation of the drive motors 23, 23 is remotely controlled by a remote control device. The remote control device includes a radio control transmitter (not shown) called “propo” that converts the control amount into a radio signal and transmits it, receives the radio signal, analyzes it, and transmits the control content to an ESC (electric A radio control receiver 26 to be transmitted to the speed controller), an ESC 27 for adjusting the amount of electricity flowing through the drive motors 23 and 23 in accordance with a control signal from the radio control receiver 26, and a battery 28 for supplying power to the ESC 27 Has been. Here, by adjusting the amount of electricity flowing through the drive motors 23 and 23 via the ESC 27, the rotational speeds of the propellers 25 and 25 are adjusted, and the speed of horizontal rotation of the support member 4 is controlled. The radio control transmitter (not shown) is operated on the ground, and the radio control receiver 26, the ESC 27, and the battery 28 are arranged on the support member 4 as a set for each drive motor 23 as shown in FIG. These are connected by a transmission cable (not shown).

  On the support member 4, a pan head 29 is disposed at a substantially central position, and the camera 59 (see FIG. 4) can be attached at an arbitrary angle by the pan head 29. When the camera 59 is a digital camera, for example, EOS-1Ds MarkII, EOS-1D MarkIIN, EOS-1D MarkII, EOS5D, EOS30D, EOS20D, and EOS20Da made by Canon can be preferably used. Can be used. On the support member 4, a wireless file transmitter 30 used for transferring a captured image is disposed near the pan head 29. As the wireless file transmitter 30, for example, WFT-E1 manufactured by Canon can be suitably used. The photographed image transferred by the wireless file transmitter 30 can be received by a ground computer constituting the wireless LAN and confirmed on a monitor. The wireless file transmitter 30 may be provided with a communication distance extension antenna (not shown) as necessary. As the communication distance extension antenna, for example, ERA-E1 made by Canon can be suitably used.

  Further, a receiver 31 of a wireless controller that controls the operation of the camera 59 is disposed on the support member 4. The wireless controller includes a transmitter (not shown) and a receiver 31, and the receiver 31 is connected to the camera 59 via a transmission cable (not shown). The operation of the camera 59 is controlled by a receiver that receives an operation control signal transmitted from the ground by the transmitter of the wireless controller, and the captured image is transferred to the ground by the wireless file transmitter 30 described above. As this wireless controller, for example, LC-5 manufactured by Canon can be suitably used. The wireless controller constitutes an operation control means for controlling the operation of the camera 59, and the camera 59 and the action control means constitute an imaging device.

  As shown in FIG. 5, a connection bolt 33 having an annular portion 32 at the lower end is attached to the lower surface of the support member 4, and a joint is connected to the annular portion 32 of the connection bolt 33 via a carabiner type connection fitting 34. The member 35 is detachably connected. The joint member 35 is composed of a fixed portion 36 connected to the carabiner-type connecting bracket 34 and a shaft portion 38 that can be horizontally rotated via a thrust bearing 37, and an annular locking formed at the lower end of the shaft portion 38. One end of the tether 5 is connected to the portion 39. The joint member 35 can prevent the tether 5 from being twisted when the balloon 2 is rotated by the wind.

  In such an aerial photographing apparatus 1, when photographing, the camera 59 is attached to the pan head 29, and the support member 4 is lifted to an arbitrary height by the balloon 2, via the operation of a radio control transmitter (not shown). By selectively driving one of the drive motors 23, 23, the thrust of the movable part 9 of the joint member 3 is generated by the thrust generated by the rotation of the propeller 25 supported by the rotation drive shaft 24 of the drive motor 23. The support member 4 is horizontally rotated in one direction through the horizontal rotation. Then, the horizontal rotation of the support member 4 is stopped through the operation of the radio control transmitter while the lens of the camera 59 is directed to a certain direction of the subject to be photographed. At this time, by driving the other drive motor 23, the horizontal rotation in one direction of the support member 4 is braked by the thrust generated by the rotation of the propeller 25 supported by the rotation drive shaft 24 of the drive motor 23. In addition, since the rotational speeds of the rotary drive shafts 24, 24 of the drive motors 23, 23 can be controlled, the rotation stop position of the support member 4 can be adjusted. In this way, with the lens of the camera 59 facing the direction of the subject, shooting is performed by controlling the operation of the camera 59 through the operation of the transmitter of the wireless controller, and then by the wireless file transmitter 30. By transferring the captured image to the ground, it is possible to acquire the captured image and check the image state of the acquired captured image.

  In such a configuration, as described above, the support member 4 is horizontally rotated by the thrust generated by the rotation of the propellers 25 and 25 supported by the rotation drive shafts 24 and 24 of the drive motors 23 and 23. Therefore, when the thrust generated by the rotation of the propellers 25 and 25 acts on the support member 4 as a rotational moment force, the movable portion 9 of the joint member 3 that suspends the support member 4 rotates horizontally to move the movable member 9. The support member 4 is horizontally rotated through the horizontal rotation of the portion 9. For this reason, almost no vibration is generated when the support member 4 is horizontally rotated, and the support member 4 can be rotated extremely smoothly and the support member 4 can be rotated once in about 2 seconds. As a result, when 360-degree shooting is performed, even if shooting is performed while the support member 4 provided with the camera 59 is rotated in the horizontal direction, no blurring due to vibration occurs, so the shot image is blurred. In addition, by increasing the rotation speed, it is possible to perform all-round imaging without being affected by the movement of the floating balloon 2 due to the wind, and no positional deviation occurs between the imaging frames. .

  In addition, a pair of drive motors 23 and 23 of the rotation drive device are disposed on the left and right sides of the support member 4, and propellers 25 and 25 that are pivotally supported on the rotation drive shafts 24 and 24 of the drive motors 23 and 23. Since the thrust generated by the rotation causes the support member 4 to rotate in the opposite direction, the drive motors 23, 23 arranged in a pair on the left and right sides of the support member 4 are selectively driven, so that The support member 4 can be selectively horizontally rotated in both the reverse and reverse directions, and the adjustment of the photographing direction in which the lens of the camera 59 is directed in the direction where the subject to be photographed can be quickly performed.

  Further, since the pair of left and right drive motors 23 and 23 are disposed on the projecting portions 22 and 22 projecting outward from the opposing edges of the support member 4, the rotation center point of the support member 4. Since the distance from the motor to the drive motors 23 and 23 becomes longer and the rotational moment force due to the thrust can be increased, the thrust is larger than when the drive motors 23 and 23 are disposed near the rotation center point. If the rotation speeds are the same, the support member 4 can be rotated faster. On the other hand, if the rotation speeds are the same, a smaller thrust may be used, so that power consumption can be suppressed.

  FIG. 6 shows a second embodiment, in which the support member 4 can be controlled to rotate by the joint member 3. Here, the joint member 3 is a cylinder fixed to the center of the upper portion of the main frame 17 of the main frame 17 of the suspension frame 16 and a fixed portion 7 having a vertical support shaft 40 with a gear 41 fixed horizontally at the lower end. A movable movable member 9, a rotation control drive motor 42 attached to the lower surface of the main frame 17, and a shaft that is supported by a rotation drive shaft 43 of the rotation control drive motor 42 to mesh with the gear 41. A gear 44 having a diameter smaller than that of the gear 41 is provided. The support shaft 40 is inserted into a cylindrical movable portion 9 from below through a through hole 62 formed at the upper center of the main frame 17 and is attached to a portion protruding upward from the movable portion 9. The C-ring 63 is rotatably held with respect to the movable portion 9. A thrust bearing 65 is interposed between the gear 41 and the reinforcing frame 18 with the support shaft 40 loosely fitted. Further, a tubular head portion 46 provided with a plurality of annular connecting portions 45 is fixed to the upper portion of the support shaft 40 through appropriate fixing means. And the fixing | fixed part 7 can be connected with the balloon 2 so that rotation is impossible by connecting the lower end of each above-mentioned rope 6 to each annular connection part 45 of this tubular head part 46. As shown in FIG. Thereby, the rotation drive mechanism which rotationally drives the support member 4 is comprised.

  The joint member 3 includes a remote rotation drive control device that remotely controls the operation of the rotation drive mechanism. The remote rotation drive control device includes the above-described radio-controlled transmitter (not shown) and a radio-controlled receiver (not shown) that receives and analyzes the radio signal and transmits the control contents to an ESC (electric speed controller). And an ESC (not shown) for adjusting the amount of electricity flowing to the rotation control drive motor 42 according to a control signal from the radio control receiver, and a battery (not shown) for supplying power to the ESC. Yes. The rotation control drive motor 42 is configured to be controlled to rotate in both forward and reverse directions. In addition, the rotation control drive motor 42 can rotate freely when the rotation drive shaft 43 is not loaded when not driven, so that even if the gear 44 meshes with the gear 41, the propeller 25 described above can be operated. The horizontal rotation of the support member 4 due to the rotation is not hindered.

  In this configuration, the rotation control drive motor 42 is driven via the operation of the radio control transmitter, and the rotation drive shaft 43 is rotated in either the forward rotation or the reverse rotation, thereby meshing with the gear 44. Since the gear 41 is in a fixed state together with the support shaft 40, the suspension frame body 16 rotates together with the movable portion 9 around the support shaft 40 via the gear 44 that rotates relative to the gear 41, and The support member 4 suspended through the holding frame body 16 can be horizontally rotated. Therefore, by controlling the rotation of the support member 4 in this manner, auxiliary fine adjustment can be easily performed at the time of adjusting the shooting direction in which the lens of the camera 59 is directed in the direction in which the subject to be shot is located.

  7 and 8 show a third embodiment. In the third embodiment, a rectangular sub-support member 47 is stepped on the lower portion of the support member 4, and a rotary drive shaft is provided on the periphery of the sub-support member 47. 49, a plurality of drive motors 48 on which propellers 50 are pivotally supported are arranged so that the support member 4 is stabilized by an outward blowing action by the rotation of each propeller 50. Here, a pair of drive motors 48 are arranged at point-symmetrical positions with respect to the center of the sub-support member 47 so as not to impair the center of gravity of the sub-support member 47. A total of six pieces are arranged, one at the edge and two at the front and rear end edges. On the sub-support member 47, a radio control receiver 51, a plurality of batteries 53, and the ESC 52 described above for each drive motor 48 are disposed, and these are connected by a transmission cable (not shown). .

  The sub-support member 47 includes a rectangular box-shaped cover body 54 that covers the entire upper portion thereof, and a side peripheral surface of the cover body 54 has a position corresponding to the rotational drive shaft 49 of each drive motor 48. Long holes 55 in the vertical direction through which the rotary drive shaft 49 can be inserted are formed. The cover body 54 is attached to the sub-support member 47 from above, and is fixed to the sub-support member 47 through appropriate fixing means such as screwing. In addition, the cover body 54 includes a plurality of connecting rods 56 protruding upward at the upper position of the side peripheral surface thereof, and the cover body 54 is formed by screws 58 inserted through through holes 57 formed in the respective connecting rods 56. The sub-support member 47 is fixed to the lower part of the support member 4. Further, a flat anti-seismic rubber 64 is attached to the upper surface of the cover body 54.

  When the sub-support member 47 is stepped on the lower portion of the support member 4 as described above, the connecting bolt 33 that connects the joint member 35 (see FIG. 5) is attached to the lower surface of the sub-support member 47.

  In this configuration, each drive motor 48 is driven through the operation of the radio control transmitter, and the rotational moment force generated by the outward blowing action by the rotation of each propeller 50 is used as the rotation center point of the sub-support member 47. By concentrating and balancing, the sub-support member 47 can be prevented from swinging, and the support member 4 to which the sub-support member 47 is attached can be stabilized.

  In addition, this invention is not limited to the structure of each Example mentioned above, In the range which does not deviate from the summary of this invention, it can change suitably. For example, in the first embodiment, a pair of drive motors 23 are arranged on the left and right sides of the support member 4, but the drive motors 23 are arranged in a single position at a position deviated from the center of the support member 4. It is also possible. Moreover, although the camera 59 disposed on the support member 4 has been described as a digital camera, the camera 59 may be a digital video camera. In this case, the operation control means of the camera includes a remote control device that controls the operation of the digital video camera on the ground, and a DV cable that connects the remote control device and the digital video camera. Furthermore, you may comprise the pan head 29 so that it can rotate to an up-down direction and a left-right direction by remote control.
