Accordingly, it is possible to suppress a blurry and blurred image when a subject is photographed by the camera.

  In addition, when a subject is photographed with a camera even in an environment where the surroundings tend to be dark, such as under a bridge girder, by irradiating light to the photographing range of the camera with an irradiation member attached to the tip of the support pole In addition, a sufficiently bright image can be obtained.

According to a second invention, in the first invention,
A support member is provided between the irradiation member and the support pole, and supports the irradiation member so that the irradiation angle can be adjusted.

  In the second invention, since the irradiation angle of the irradiation member can be adjusted, the irradiation angle can be adjusted so that the captured image of the camera has sufficient brightness.

  According to the present invention, even when the tip of the support pole is tilted, the camera is automatically maintained in a horizontal posture by the posture maintaining member. Can be suppressed. In addition, by irradiating light to the shooting range of the camera with the irradiation member, an image with sufficient brightness can be obtained even in an environment where the surroundings tend to be dark, such as under a bridge girder.

The operator operates the second motor 39 (see FIG. 2) and turns the camera 30 in the vertical direction while viewing the video displayed on the monitor 15, so that the elevation angle of the camera 30 is increased. Can be adjusted.

  As will be described later, in this embodiment, the first motor 37 (see FIG. 2) is automatically controlled so that the camera 30 is always maintained in a horizontal posture. The tilt angle of the camera 30 can also be manually adjusted by operating the motor 37 and rotating the camera 30 in the horizontal direction.

  Further, by operating the controller 16, the shutter shooting of the camera 30 can be performed. When the monitor 15 is configured with a touch panel tablet or the like, the shutter shooting of the camera 30 may be performed by touching a shutter button displayed on the screen of the monitor 15.

  As shown in FIGS. 2 and 3, the photographing unit 20 includes a pole side pedestal 21 attached to the tip of the support pole 11, a camera side pedestal 31 on which a camera 30 is mounted, a pole side pedestal 21, and a camera side. And a mount member 40 as a posture maintaining member provided between the base 31 and the base 31.

  The pole side pedestal 21 is provided with four pole side arms 22 that project outward in the radial direction. The pole-side pedestal 21 is provided with a battery mounting table 23 having an L-shaped cross section that extends downward along the support pole 11 and then projects forward. A battery 24 is mounted on the battery mounting table 23.

  The battery 24 supplies power to the control unit 36, the first motor 37, and the second motor 39. The battery 24 is detachably held with respect to the battery mounting table 23 by a holding metal fitting 25. A lever switch 26 for turning on / off the power supply of the battery 24 is provided on the opposite side of the battery mounting base 23 across the support pole 11 in the pole side base 21.

  The camera side pedestal 31 is provided with four camera side arms 32 that project outward in the radial direction. The camera-side base 31 is provided with two antennas 33 extending in the horizontal direction. The antenna 33 is used for wireless communication of signals between the ground monitor 15 and the controller 16, and an image captured by the camera 30 is transmitted to the monitor 15 via the antenna 15 a or output from the controller 16. Control signal is received and transmitted to the receiver 35.

  A support column 34 extending upward is provided at the center of the camera side pedestal 31. A receiving unit 35 that receives a control signal via the antenna 33 is provided on the back surface of the column unit 34. Below the central portion of the camera-side pedestal 31, various controls such as driving the first motor 37 and the second motor 39 and performing shutter photographing of the camera 30 based on the control signal received by the receiver 35. The control part 36 to perform is attached.

  A first motor 37 is attached to the upper end portion of the column portion 34. The first motor shaft 37a of the first motor 37 extends in the horizontal direction (left-right direction in FIG. 5). A camera holding portion 38 is attached to the distal end portion of the first motor shaft 37a.

  A second motor 39 is attached to the camera holding unit 38. The second motor shaft 39a of the second motor 39 extends in the horizontal direction so as to be orthogonal to the first motor shaft 37a (the direction orthogonal to the paper surface in FIG. 5). A camera 30 is attached to the tip of the second motor shaft 39a.

  Here, the first motor 37 is automatically controlled so that the camera 30 is always maintained in a horizontal posture, and constitutes a posture maintaining member. Specifically, when the tilt sensor or the like (not shown) detects that the camera 30 is tilted by a predetermined angle with respect to the horizontal direction, the control unit 36 sets the first motor 37 in the direction in which the camera 30 is in the horizontal posture. Drive. Thereby, the camera 30 can be rotated in the horizontal direction together with the camera holding unit 38, and the horizontal inclination angle of the camera 30 can be automatically adjusted.

  Further, by operating the controller 16 to drive the second motor 39, the camera 30 can be rotated in the vertical direction, and the vertical tilt angle of the camera 30, that is, the elevation angle can be manually adjusted.

  An elastically deformable mount member 40 is sandwiched between the camera side arm 32 and the pole side arm 22. The mount member 40 is integrally provided with flange portions 41 at both ends in the vertical direction. The mount member 40 is formed with a through hole 42 penetrating in the vertical direction.

  The pole side arm 22 and the camera side arm 32 are formed with fitting holes 22a and 32a into which both ends of the mount member 40 in the vertical direction are fitted, respectively. The flange portion 41 of the mount member 40 functions as a retainer for preventing the mount member 40 from falling off the fitting holes 22a and 32a.

  The mount member 40 is fastened together between the pole side arm 22 and the camera side arm 32 by a fastening bolt 45 and a fastening nut 46. Specifically, the fastening bolt 45 is inserted from the camera side arm 32 side toward the through hole 42, and the fastening nut 46 is fastened to the shaft portion of the fastening bolt 45 protruding from the pole side arm 22. The mount member 40 is fitted between the camera side arm 32 and the camera side arm 32 so as to be elastically deformable.

  As shown in FIG. 4, the upper end of the support pole 11 may bend due to the influence of the wind, and the pole-side arm 22 may be inclined with respect to the horizontal direction. At this time, the mount side 40 is elastically deformed, so that the camera side arm 32 is automatically maintained in a horizontal posture. That is, the camera 30 mounted on the camera side pedestal 31 integrally formed with the camera side arm 32 is also automatically maintained in a horizontal posture. Further, the first motor 37 also automatically controls the tilt angle of the camera 30 in the horizontal direction, and the camera 30 is automatically maintained in a horizontal posture. Thereby, when the subject is photographed by the camera 30, it is possible to suppress a blurry and blurry image.

  As shown in FIG. 5, an irradiation member 50 is disposed at a position below the battery 24 at the upper end portion of the support pole 11. The irradiation member 50 is for irradiating light to the imaging range of the camera 30, and is configured by, for example, an LED light.

  The irradiation member 50 is supported on the support pole 11 by a pair of support members 51 disposed in a direction orthogonal to the paper surface in FIG. An insertion hole 51 a through which the fastening bolt 55 is inserted is formed in the upper end portion and the lower end portion of the support member 51.

  An irradiation side fixing ring 52 fitted to the outer peripheral surface of the irradiation member 50 is attached to the irradiation member 50. The irradiation side fixing ring 52 is formed with a screw hole (not shown) to which the fastening bolt 55 is screwed, corresponding to the insertion hole 51 a on the upper end side of the support member 51.

  A pole-side fixing ring 53 that is fitted to the outer peripheral surface of the support pole 11 is attached to the support pole 11. The pole-side fixing ring 53 is formed with a screw hole (not shown) to which the fastening bolt 55 is screwed, corresponding to the insertion hole 51 a on the lower end side of the support member 51.

  Then, the fastening bolt 55 is inserted into the insertion hole 51 a at the upper end portion of the support member 51 and fastened to the screw hole of the irradiation side fixing ring 52, while the fastening bolt 55 is inserted into the insertion hole 51 a at the lower end portion of the support member 51. Then, the irradiation member 50 is supported by the support pole 11 by being fastened to the screw hole of the pole-side fixing ring 53.

  Here, the irradiation angle of the irradiation member 50 can be arbitrarily set by tightening the fastening bolt 55 after adjusting the angles of the support member 51 and the irradiation member 50 with the fastening bolt 55 loosened. The configuration of the support member 51 is merely an example, and any configuration may be used as long as the irradiation member 50 can be supported so that the irradiation angle can be adjusted.

  With such a configuration, the surroundings such as the lower position of the bridge girder 1 are likely to be darkened by irradiating the shooting range of the camera 30 with the irradiation member 50 attached to the tip of the support pole 11. Even under the environment, when the subject is photographed by the camera 30, an image with sufficient brightness can be obtained.

  In the present embodiment, it is assumed that the irradiation angle of the irradiation member 50 is set in advance by the operator on the ground. For example, a motor (not shown) is provided on the support member 51 and the operation is performed by the controller 16. Thus, the irradiation angle of the irradiation member 50 may be adjustable by remote control.

  As described above, the present invention provides a highly practical effect that a clearer image can be taken using a camera attached to the tip of the support pole. The possibility is high.
