Description

  The present invention relates to a digital disaster prevention wireless system that transmits a photographed image photographed by a photographing apparatus that can freely move in a photographing direction to a disaster prevention management server via wireless, a position control method for the photographing apparatus, and a program.

  A conventional digital disaster prevention broadcast radio system (for example, Patent Document 1) includes a plurality of outdoor loudspeakers for a loudspeaker broadcast to an outdoor loudspeaker from an operation console that is a master station of the digital disaster prevention broadcast radio system. This is a method in which two districts are set and broadcasting is performed for the set districts.

In this digital disaster prevention broadcast wireless system, when transmitting images in digital disaster prevention, a camera is installed in advance in the direction you want to shoot, and if this camera is movable, the digital disaster prevention broadcast wireless system is in operation. In addition, the camera is moved up and down and left and right to perform shooting.
Japanese Patent Laid-Open No. 05-175961

  However, since the digital disaster prevention broadcast wireless system is the main system that broadcasts by sound, the image transmission is terminated when the audio broadcast notified from the master station starts even during image transmission on the digital disaster prevention system. . Therefore, the conventional digital disaster prevention broadcast wireless system has the following problems.

  The first problem is that when image transmission is completed in a state where the direction is changed from the shooting direction when the camera is installed, next time transmission is started with an image shot in that shooting direction.

  The second problem is that when the audio broadcast starts during image transmission, the shooting ends. Therefore, if the place where you want to shoot is not in front of the camera installation in the event of a disaster, Although the direction has to be corrected, since the wireless system is used, it is difficult to correct the direction of the camera because it is impossible to see a complete moving image as in the case of using a Web camera.

  The third problem is that when the camera can only move relative to the current position, it recognizes not the shooting direction (position) when the camera is installed but the position at the end of shooting as the center. The point is that the camera can be moved in the shooting direction, which is outside the operating range of the camera.

(the purpose)
An object of the present invention is to provide a digital disaster prevention broadcast wireless system capable of easily correcting the shooting direction of a camera.

  The present invention provides a digital disaster prevention wireless system that transmits a photographed image photographed by a photographing apparatus that can freely move in a photographing direction to a disaster prevention management server via wireless, in which the photographing apparatus stores position control information stored in advance or Means for adjusting the shooting start position based on the position control information transmitted from the disaster prevention management server, and means for transmitting the shot images sequentially shot from the adjusted shooting start position to the disaster prevention management server. It is characterized by.

(Function)
With the above configuration, the imaging apparatus of the present invention transmits captured images sequentially captured from the adjusted imaging start position to the disaster prevention management server.

  According to the present invention, the following effects can be achieved.

  The first effect is that, since the imaging device sequentially transmits captured images taken from the adjusted imaging start position to the disaster prevention management server, it is possible to always start imaging from the position (imaging direction) where the imaging device is installed. .

  The second effect is that the image capturing apparatus transmits captured images sequentially captured from the adjusted capturing start position to the disaster prevention management server, so that even if only relative movement is possible, the permitted operating range is not exceeded.

Hereinafter, the operation of the digital disaster prevention broadcast radio system according to the present embodiment will be described in detail with reference to the drawings.

  4 and 5 are flowcharts showing the operation of the digital disaster prevention broadcast wireless system according to this embodiment. FIG. 4 shows the operation at the start of shooting, and FIG. 5 shows the operation at the end of shooting. is there.

  First, as an initial setting, the imaging unit 10, the audio output unit 20, the imaging side communication unit 30, the control unit 40, and the control side communication unit 50 are installed at predetermined positions with respect to the imaging target 60. The reference position information 171 of the photographing unit 10 is stored in the storage unit 171 of the photographing unit 10, and the photographing start position control information 421 for controlling the photographing start position of the photographing unit 10 is held by the holding unit 42 of the control unit 40. And

  2 and 4, when the control unit 40 instructs the imaging unit 11 of the imaging unit 10 to start (step S101), the imaging start position control information 421 held by the holding unit 42 is acquired. (Step S102) The start instruction for the photographing means 11 and the obtained photographing start position control information 421 are notified to the control side communication unit 50 (Step S103). That is, the control unit 40 may notify the shooting start position control information 421 indicating the shooting direction when the shooting unit 10 is installed, or notify the shooting start position control information 421 indicating another predetermined shooting direction. May be. In step S102 and step S103, the control unit 40 may notify the activation instruction to the imaging unit 11 and the input imaging start position control information 421 on the control side communication unit 50.

  The activation instruction and the imaging start position control information 421 notified to the control side communication unit 50 are notified to the imaging unit 10 via the imaging side communication unit 30 (step S104).

  When the shooting start position control information 421 is notified, the shooting direction recognizing unit 13 adds the recognized shooting direction of the shooting unit 10 itself and the notified shooting start position control information 421 based on the reference position information 171. A difference from the indicated position (photographing direction) is recognized (step S105).

  If there is a difference in step S105, the control unit 14 rotates, for example, based on the current shooting direction of the shooting unit 10 recognized by the shooting direction recognition unit 13 and the notified shooting start position control information 421. The shooting start position is adjusted (step S106), and when the predetermined shooting start position is reached (when the shooting unit 10 faces the set shooting start direction) (step S107), the shooting unit 11 is activated to set the shooting target. Shooting of the object 60 is started (step S108).

  If there is no difference in step S105, the control means 14 activates the photographing means 11 at the position (direction) to start photographing the photographing object 60 (step S108).

  Next, referring to FIG. 2 and FIG. 5, during the photographing of the photographing object 60 by the photographing unit 11, when the control unit 40 instructs the stop of the photographing unit 11, or the sound output unit 20 outputs the sound. When the operation of the photographing unit 11 is terminated by the operation ending unit 16 (including the case where the photographing unit 11 is forcibly terminated) (step S201), the photographing direction recognition unit 13 recognizes based on the reference position information 171. A difference between the current shooting direction of the shooting unit 10 itself and the position (shooting direction) indicated in the shooting start position control information 421 notified when the shooting unit 11 is activated is recognized (step S202).

  If there is a difference in step S202, the control unit 14 compares the current shooting direction of the shooting unit 10 recognized by the shooting direction recognition unit 13 and the shooting start position control information 421 notified when the shooting unit 11 is activated. Based on this, the position (direction) of the photographing unit 10 after photographing is adjusted by, for example, rotational movement (step S203), and when the photographing unit 10 reaches a predetermined position (direction) (of the photographing unit 10 after photographing is finished). When the position (direction) faces the set shooting start direction (step S204), the movement of the shooting unit 10 is stopped (step S205), and the shooting unit 10 is set in a standby state (step S206).

  On the other hand, if there is no difference in step S202, the control unit 14 places the photographing unit 10 in a standby state at the position (direction) (step S206).

(Effects of the first embodiment)
According to the present embodiment, the photographing unit 10 can automatically move to the photographing start position simultaneously with the end of image transmission.

  Further, according to the present embodiment, the photographing unit 10 can automatically move to the photographing start position simultaneously with the end of the image transmission, and therefore the photographing object 60 is at the photographing start position (front) of the photographing unit 10. Can start photographing the object 60 from the front as it is at the start of the next photographing. For example, when the position (shooting direction) where the shooting unit 10 is installed is set as the shooting start position control information 421, the shooting unit 10 automatically sets the position (shooting direction) where the shooting unit 10 is installed simultaneously with the end of image transmission. ), The shooting can always be started from the position (shooting direction) where the shooting unit 10 is installed at the start of the next shooting.

  In addition, according to the present embodiment, the imaging unit 10 can always start imaging from the position (imaging direction) where the imaging unit 10 is installed at the time of the next imaging start, and thus is allowed even when only relative movement is possible. The operating range is not exceeded.

  The reason is indicated by the current shooting direction of the shooting unit 10 recognized by the shooting direction recognition unit 13 based on the reference position information 171 and the shooting start position control information 421 notified when the shooting unit 11 is activated. Recognizing the difference from the position (shooting direction), the control unit 14 controls the current shooting direction of the shooting unit 10 recognized by the shooting direction recognition unit 13 and the shooting start position control notified when the shooting unit 11 is activated. Based on the information 421, the position (direction) of the photographing unit 10 after photographing is adjusted by, for example, rotational movement, and when the photographing unit 10 reaches a predetermined position (direction) (of the photographing unit 10 after photographing is finished). This is because the movement of the photographing unit 10 is stopped and the photographing unit 10 is set in a standby state (when the position (direction) is directed to the set photographing start direction).

(Second Embodiment)
Hereinafter, a digital disaster prevention broadcast wireless system according to a second embodiment of the present invention will be described with reference to the drawings. The configuration and operation of the digital disaster prevention broadcast radio system according to the present embodiment are the same as the configuration and operation of the first embodiment.

  In the present embodiment, for example, when the shooting target 60 moves to the position of the shooting target 70 or when the shooting target 60 is changed to the shooting target 70, the shooting unit 10 starts shooting at the start of shooting. A case where the object to be imaged cannot be imaged at the position will be described.

(Configuration of Second Embodiment)

  When receiving a notification from the holding means 42 that the new shooting start position control information 421 has been held (step S302), the control unit 40 moves to the position of the shooting target 70 indicated by the new shooting start position control information 421. Then, the control side communication unit 50 is notified of an instruction to restart the photographing unit 11 (step S303). That is, the control unit 40 notifies the control-side communication unit 50 of an activation instruction for the imaging unit 11 and new imaging start position control information 421 in step S303.

  The activation instruction and new imaging start position control information 421 notified to the control side communication unit 50 are notified to the imaging unit 10 via the imaging side communication unit 30 (step S304).

  When the new shooting start position control information 421 is notified, the shooting direction recognizing means 13 is notified of the current shooting direction of the recognized shooting unit 10 itself based on the reference position information 171 and the notified shooting start position control information. It is recognized that there is a difference from the position (photographing direction) indicated by 421 (step S305).

  Based on the current shooting direction of the imaging unit 10 recognized by the shooting direction recognition unit 13 and the notified new shooting start position control information 421, the control unit 14 sets the shooting start position by, for example, rotational movement. When adjustment is made (step S306) and a new shooting start position is reached (when the shooting unit 10 faces in the set new shooting start direction) (step S307), the shooting unit 11 is activated to shoot the shooting target 60. Is started (step S308).

  When the holding unit 42 holds a plurality of shooting start position control information 421 for each shooting direction in advance, the control unit 14 sequentially sets each shooting start position control information 421 in step S301, or By notifying the photographing unit 10 of appropriate photographing start position control information 421 via the control side communication unit 50 and the photographing side communication unit 30, the photographing unit 10 can be moved in an appropriate photographing start direction. .

  In step S301 to step S303, the control unit 14 selects any one of the reference position information 171 and the shooting start position control information 421 in the storage unit 17 and instructs to adjust the shooting position of the shooting unit 10. May be.

  In step S303, the control unit 40 gives an instruction to stop the photographing unit 11 before the movement of the position of the photographing unit 10 in addition to the start instruction of the photographing unit 11 and the new photographing start position control information 421. You may notify with respect to the communication part 50. FIG.

  FIG. 8 is a schematic diagram for explaining the digital disaster prevention broadcast wireless system according to the present embodiment. By the above-described operation, the photographing unit 10 moves at the start of photographing, and the photographing object is at a new photographing start position. FIG.

(Effect of the second embodiment)
According to the present embodiment, when the shooting target 60 has moved to the position of the shooting target 70, or when the shooting target 60 has been changed to the shooting target 70, the shooting unit 10 is predetermined at the start of shooting. Even when the photographing object cannot be photographed at the photographing start position, or when the photographing unit 10 stops moving at a position other than the photographing start position due to the start of the audio broadcasting, the photographing unit 10 does not change the position (shooting direction). ) Can be easily corrected, so that shooting can be performed from a specific position (shooting direction) set by the controller 40 at the start of shooting.

  In addition, according to the present embodiment, since the shooting direction at the start of shooting can be easily corrected, the shooting unit 10 can be installed without worrying about the position (shooting direction) at the start of shooting.

  Further, according to the present embodiment, since the shooting direction at the start of shooting can be easily corrected, it is necessary to re-install the shooting unit 10 in order to change the position (shooting direction) at the start of shooting. Absent.

  The reason is that the holding unit 42 newly holds shooting start position control information 421 indicating the position of the shooting target 70 or holds a plurality of shooting start position control information 421 for each shooting direction in advance. 14, for example, notifies each photographing start position control information 421 sequentially or appropriate photographing start position control information 421 to the photographing unit 10 via the control side communication unit 50 and the photographing side communication unit 30. This is because the photographing unit 10 can be moved in an appropriate photographing start direction. That is, according to the present embodiment, it is possible to easily change the initial direction of the start of photographing only by changing the setting of the control unit 40.

  Further, according to the present embodiment, the control unit 14 selects any one of the reference position information 171 and the shooting start position control information 421 in the storage unit 17 and instructs the adjustment of the shooting position of the shooting unit 10. This is because the initial direction of the start of photographing can be easily changed.
