Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram showing an overall configuration of a monitoring system 1 according to an embodiment of the present invention. The monitoring system 1 is a system for monitoring a place where an event such as a marathon event is held. The monitoring system 1 includes a server device 10, a plurality of monitor terminals 20, a plurality of mobile terminals 30, a plurality of camera devices 40, and an operation terminal 50. The server device 10 communicates with each of the plurality of supervisor terminals 20, the plurality of portable terminals 30, and the plurality of camera devices 40 via the communication line NW1. The communication line NW1 is a public communication line including, for example, the Internet and a wireless communication network. The server device 10 communicates with the operation terminal 50 via the communication line NW2. The communication line NW2 is a communication line including, for example, a LAN (Local Area Network). The server device 10 and the operation terminal 50 are arranged in a monitoring center for monitoring the place where the event is held.
Note that the communication lines NW1 and NW2 may be either wired or wireless communication lines.

  When an abnormality occurs at the event location, the server device 10 performs a process for instructing the supervisor U to deal with the abnormality. The monitoring person U is a person who performs monitoring at a place he is in charge of under a predetermined monitoring system. The monitoring system indicates the arrangement of a plurality of monitoring personnel U. If any abnormality occurs, the monitoring staff U takes measures against the abnormality. In the present embodiment, “abnormal” refers to an event that may prevent the event or the participant from proceeding, such as a suspicious person, a suspicious object (for example, a dangerous object), and an injured person. It may be decided how to determine which event is abnormal. The monitoring staff U includes various personnel such as personnel responsible for security, personnel responsible for medical rescue, or personnel involved in event management. In FIG. 1, four monitoring personnel U1 to U4 are shown as the monitoring personnel U.

  The monitor terminal 20 and the portable terminal 30 are terminal devices carried by the monitor U in the monitored area. The supervisor terminal 20 is a wearable terminal device having a communication function and an imaging function. In this embodiment, the monitor terminal 20 is attached to a chest position that is a part of the body part of the monitor U. For this reason, the supervisor terminal 20 captures images with the direction of the line of sight of the supervisor U as the imaging direction. In the present embodiment, the imaging range is regarded as equivalent to the field of view of the monitoring person U. The mobile terminal 30 is, for example, a smartphone. However, the mobile terminal 30 may be a mobile terminal having a communication function, such as a tablet computer.

  The plurality of camera devices 40 are installed (fixed) at predetermined locations. The camera device 40 images the monitoring area assigned to the device itself, and transmits image data indicating the captured image to the server device 10. The camera device 40 is installed at a high place such as a street lamp or a utility pole, for example, and images an oblique downward direction, for example. However, the installation location of the camera device 40 may be any location, and the imaging direction may be any direction.

  The operation terminal 50 is a computer device used by an operator in the monitoring center. The operation terminal 50 displays an image of the place where the event is held based on the image data collected by the server device 10 from the plurality of camera devices 40 and the plurality of monitor terminals 20. The operation terminal 50 is used for inputting / outputting information to / from the server device 10.

  FIG. 2 is a diagram illustrating an example of the configuration of the server device 10. As shown in FIG. 2, the server device 10 includes a control unit 11, a first communication unit 12, a second communication unit 13, and a storage unit 14. The control unit 11 controls each unit of the server device 10. The control unit 11 includes a processor including a central processing unit (CPU), a read only memory (ROM), and a random access memory (RAM) as an arithmetic processing unit. The CPU controls each unit of the server device 10 by reading the program stored in the ROM or the storage unit 14 into the RAM and executing the program. The first communication unit 12 communicates with the monitor terminal 20, the mobile terminal 30, and the camera device 40 via the communication line NW1. The second communication unit 13 communicates with the operation terminal 50 via the communication line NW2. The first communication unit 12 and the second communication unit 13 include, for example, a modem. The storage unit 14 stores a program executed by the control unit 11 and a monitoring system table 141. The monitoring system table 141 is a table for managing a monitoring system plan indicating the arrangement (monitoring system) of a plurality of monitoring personnel that changes with the passage of time. In this embodiment, the monitoring system plan changes as the event progresses. The storage unit 14 includes, for example, a hard disk.

FIG. 3 is a diagram illustrating an example of the configuration of the monitoring system table 141. In the monitoring system table 141, information such as “date and time”, “monitoring person ID”, “monitoring position”, “monitoring direction”, “duty”, and “moveability” is associated with each other. In the “date and time” field, the date and time when monitoring in the monitoring system is executed is stored. The identifier of the supervisor U is stored in the “monitorer ID” field. The supervisor IDs “UID001”, “UID002”, “UID003”, and “UID004” indicate the supervisors U1, U2, U3, and U4 in this order. In the “monitoring position” field, information on the position (location) where the monitoring staff U should be monitoring is stored. Here, the monitoring position is expressed using identifiers such as A point, B point,... For example, an expression using latitude and longitude, or an expression using a place name such as “XX building” can be considered. In the “monitoring direction” field, information on the direction in which the supervisor U should face during monitoring is stored. In the present embodiment, the monitoring direction is expressed using a direction. In the “task” field, information on the task of the supervisor U is stored. In this embodiment, it is assumed that there are “security”, “medical relief”, and “management”, but there may be other duties. Information on whether or not to permit the monitoring staff U to leave the monitoring position planned in the monitoring system table 141 when an abnormality occurs is stored in the “Moveability” field. In the present embodiment, the mission of the supervisor U and whether or not the supervisor U can move correspond to “role” in the surveillance of the supervisor U, respectively.
The monitoring system table 141 is created before the event is held and is stored as a monitoring system plan. However, the monitoring system table 141 may be updated by the function of the server device 10.

Returning to FIG. 2, the function of the control unit 11 will be described. The control unit 11 includes an abnormality detection unit 111, an acquisition unit 112, a selection unit 113, an update unit 114, and a notification unit 115. Each function of the control unit 11 is realized by cooperation of a processor and a program executed by the processor.
The abnormality detection unit 111 executes an abnormality detection process that is a process of detecting an abnormality that may occur at the event location. For example, the abnormality detection unit 111 performs an abnormality detection process by analyzing image data acquired from the camera device 40 using the first communication unit 12. A known image analysis can be used for this analysis. Moreover, the abnormality detection part 111 can also acquire the information input by the operator from the operation terminal 50 using the 2nd communication part 13, and can detect abnormality based on this information. An abnormality detection method is not particularly limited.

  The acquisition unit 112 uses the first communication unit 12 to acquire imaging range information that identifies the imaging range of each of the monitoring personnel terminals 20 of the plurality of monitoring personnel U. The imaging range information is information for specifying a range included in an image captured by the supervisor terminal 20. The imaging range changes depending on the position of the supervisor terminal 20 or the direction (orientation) in which the supervisor terminal 20 faces.

  When determining that an abnormality has been detected by the abnormality detection unit 111, the selection unit 113 selects, from among the plurality of monitoring staff U, the monitoring staff U as a handling staff who issues a handling instruction for the abnormality that has occurred. The selection unit 113 performs this selection based on the imaging range information acquired by the acquisition unit 112. It should be noted that the monitoring staff U who is instructed to deal with the abnormality that has occurred corresponds to the “handling staff” of the present invention, whereas the monitoring staff U who has not performed the handling instruction corresponds to the “non-handling staff” of the present invention. To do.

  The update unit 114 updates the monitoring system table 141. The updating unit 114 updates the monitoring system table 141 based on the monitoring system plan of the other monitoring personnel U when the monitoring personnel U selected by the selection unit 113 are dealing with the abnormality.

  The notification unit 115 uses the first communication unit 12 to instruct the monitoring staff U selected by the selection unit 113 to deal with the abnormality. Further, based on the result of the update of the monitoring system table 141 by the update unit 114, the notification unit 115 notifies the monitor U who is affected by the update to that effect. Here, the monitoring terminal U's mobile terminal 30 is the notification destination.

FIG. 4 is a diagram illustrating an example of the configuration of the supervisor terminal 20. As shown in FIG. 4, the supervisor terminal 20 includes a control unit 21, a camera 22, a sensor unit 23, a storage unit 24, and a communication unit 25.
The control unit 21 controls each unit of the camera device 40. The control unit 21 has a processor including a CPU, a ROM, and a RAM as an arithmetic processing unit. The CPU controls each unit of the camera device 40 by reading the program stored in the ROM or the storage unit 24 into the RAM and executing it. The camera 22 images the monitoring area and generates image data indicating the captured image. The camera 22 includes an image sensor and a lens exemplified by a CCD (Charge Coupled Device). The camera 22 typically generates image data indicating a moving image, but may generate image data indicating a still image (photograph).

  The sensor unit 23 includes one or a plurality of sensors. The sensor unit 23 includes, for example, an acceleration sensor, a gyro sensor, a GPS (Global Positioning System) sensor, and an orientation sensor. The position of the monitoring person U is specified using, for example, a GPS sensor. The direction monitored by the monitoring person U is specified by using, for example, a direction sensor. The storage unit 24 stores a program executed by the control unit 21 and image data generated by the camera 22. The storage unit 24 stores information related to the performance of the camera 22 including the angle of view of the camera 22 and the imageable distance. The storage unit 24 includes, for example, a flash memory. The communication unit 25 communicates with the server device 10 via the communication line NW1. The communication unit 25 includes, for example, a wireless communication circuit and an antenna.

FIG. 5 is a sequence chart showing processing executed in the monitoring system 1.
In the server device 10, the abnormality detection unit 111 executes abnormality detection processing (step S1). Next, the abnormality detection unit 111 determines whether an abnormality has occurred based on the result of the abnormality detection process (step S2). If it is determined “NO” in step S2, the abnormality detection unit 111 repeatedly performs the processes of steps S1 and S2.

When it is determined by the abnormality detection unit 111 that an abnormality has occurred (step S2; YES), the acquisition unit 112 uses the first communication unit 12 to capture an image of the monitoring terminal 20 carried by a plurality of monitoring personnel U Is acquired (step S3). For example, when it is determined in step S2 that an abnormality has occurred, the acquisition unit 112 requests the plurality of monitor terminals 20 to transmit imaging range information for specifying the imaging range, and acquires the imaging range information. When the imaging range information is spontaneously transmitted from each of the plurality of monitor terminals 20, the acquisition unit 112 may acquire the latest imaging range information. As described above, the imaging range information is information that specifies an imaging range at a timing when an abnormality has occurred or an imaging range at a timing that can be regarded as a timing at which an abnormality has occurred. In the monitor terminal 20, the control unit 21 generates imaging range information based on information from the sensor unit 23, characteristics of the camera 22, and information related to settings. The imaging range information includes, for example, an imaging position, an imaging distance, an imaging direction, an angle of view, and the like, but may include information other than these, or may not include some information. Further, the imaging range information may include image data of a captured image. The control unit 21 transmits imaging range information to the server device 10 using the communication unit 25.
Note that only the imaging position and the imaging direction are transmitted from the monitor terminal 20 to the server device 10, and the server device 10 receives the camera 22 characteristic data such as the angle of view of the camera 22 and the imaging distance set in advance. It may be used to generate imaging range information of each monitor terminal 20.

Next, the selection unit 113 selects a monitor U to deal with the abnormality that has occurred based on the imaging range information of each monitor terminal 20 acquired by the acquisition unit 112 (step S4).
Here, a case where a monitoring system of “2017/02/01 9:00 to 9:20” is laid out based on the monitoring system table 141 will be considered. In this case, as shown in the upper diagram of FIG. 6, the monitoring personnel U1 to U4 are arranged. The monitoring personnel U1, U2, U3, and U4 are arranged so as to face the “south” which is the monitoring position at substantially equal intervals and the same monitoring direction. The imaging ranges specified by the imaging range information about the supervisors U1, U2, U3, and U4 are sequentially expressed as imaging ranges T1, T2, T3, and T4. Here, the imaging ranges T1, T2, T3, and T4 are fan-shaped ranges.

  Here, as shown in the upper part of FIG. 6, a case where an abnormality occurs at the abnormality occurrence position P in the imaging range T3 of the monitoring person U3 is considered. In this example, the monitoring personnel U1, U2, U3, and U4 are arranged at substantially equal intervals of monitoring positions and facing the same monitoring direction. Therefore, there is no bias in the distribution of the plurality of imaging ranges corresponding to the monitoring personnel U1, U2, U3, U4. In this case, no matter which one of the monitoring personnel U1, U2, U3, U4 leaves the monitoring system, there is no great difference in the bias of the imaging range after the departure, that is, there is no significant difference in the influence on the monitoring system. . In such a case, the selection unit 113 selects, for example, a monitoring person U whose abnormality occurrence position is present in the imaging range from among the monitoring persons U whose “movement possibility” field is “available” in the monitoring system table 141. To do. Here, the selection part 113 selects the monitoring person U3. Even when there are a plurality of monitoring personnel U where an abnormality occurrence position exists in the imaging range, or when the abnormality occurrence location is not included in the imaging range of any monitoring personnel U, the selection unit 113 is the most in the abnormality occurrence position P. It is recommended to select a close monitor U. This is because it is possible to quickly cope with the abnormality.

  Next, the notification unit 115 uses the first communication unit 12 to instruct the monitoring person U selected by the selection unit 113 to deal with the abnormality (step S5). Here, the notification unit 115 sends a notification related to the handling instruction to the mobile terminal 30 of the monitoring person U3. In response to this handling instruction, the monitoring person U3 moves to the abnormality occurrence position P to deal with the abnormality.

  By the way, when the supervisor U3 leaves the original monitoring system, the monitoring system is disturbed. If the monitoring system of the monitoring personnel other than the monitoring personnel U3 is left as it is, a range that does not belong to any imaging range between the monitoring personnel U2 and the monitoring personnel U4, as shown in the lower diagram of FIG. In other words, a “non-monitoring range” B that is a range in which monitoring is not performed is formed. In order to suppress the existence of such a non-monitoring range B as much as possible, the server apparatus 10 performs the following processing.

The update unit 114 updates the monitoring system table 141 (step S6). Here, the update unit 114 updates the monitoring system table 141 shown in FIG. FIG. 8 is a diagram showing an example of a monitoring system plan after the occurrence of an abnormality based on the updated monitoring system table 141.
As can be seen from FIGS. 7 and 8, the updating unit 114 keeps the monitoring position “A point” for the monitoring person U1 with the monitoring person ID “UID001” and changes the monitoring direction from “south” to “south southeast”. Change to Further, the updating unit 114 changes the monitoring position to “A-B point” while the monitoring direction remains “south” for the monitoring person U2 with the monitoring person ID “UID002”. The notation “◯ −Δ point” indicates that a monitoring point is a point between the ○ point and the Δ point, for example, an intermediate point. In addition, the updating unit 114 changes the monitoring direction from “D point” to “CD point” (that is, an intermediate point between the C point and the D point) for the monitoring person U4 with the monitoring person ID “UID004”. Change from South to South South. Accordingly, the imaging ranges T2 and T4 exist in a part of the range where the imaging range T3 existed, and the imaging range T1 exists in a part of the range where the imaging range T2 originally existed. The monitoring range becomes smaller.

  Returning to FIG. The notification unit 115 notifies the monitoring staff U of the changed monitoring system plan based on the monitoring system table 141 updated by the updating unit 114. Here, the notification unit 115 instructs the monitoring personnel U1, U2, U4 affected by the update to change the monitoring system (steps S7, S8, S9). Upon receiving the change instruction, the monitoring personnel U1, U2, and U4 change the monitoring system as shown in FIG. 8 according to the contents of the notification.

  The supervisor U3 who has received the handling instruction returns to the original monitoring system when the handling of the abnormality is completed. At this time, the update unit 114 updates the monitoring system table 141 to the state shown in FIG. And the notification part 115 notifies the monitoring staff U1, U2, U4 so that it may return to the original monitoring system. The timing for completing the handling of the abnormality may be determined based on a notification from the mobile terminal 30 or the monitor terminal 20, or may be determined to be completed after a predetermined scheduled handling time.

  In the example of FIG. 6, a case where an abnormality has occurred in the imaging range of a certain supervisor U in a situation where there is no non-supervised range among a plurality of supervisors U is shown. The same applies when an abnormality occurs when a non-monitoring range originally exists between the two. The selection unit 113 assumes that any one of the monitoring staff U has left the current monitoring system for coping, and selects the monitoring staff U with the smallest non-monitoring range in that case. That is, the selection unit 113 selects the monitoring person U to deal with the abnormality in consideration of the distribution of the plurality of imaging ranges. Further, even when the abnormality occurrence position is not included in the imaging range of any monitor U, the same processing can be performed.

By the way, there are various methods for selecting the supervisor U in step S4.
(1) The selection unit 113 can also select the monitoring person U to deal with the abnormality based on the deviation of the distribution of the imaging range among the plurality of monitoring persons U. Here, a case where a monitoring system of “2017/02/01 11: 00 to 11:30” is laid out based on the monitoring system table 141 is considered. In this case, as shown in FIG. 9, monitoring personnel U1-U4 are arranged. Here, consider a case where an abnormality occurs at the abnormality occurrence position P within the imaging range T2 of the monitoring person U2. In this case, the selection unit 113 performs monitoring so that the non-monitoring range in response to the abnormality is minimized among the monitoring personnel U whose “movement possibility” field in the monitoring system table 141 is “enabled”. Select person U. Since the imaging region T2 includes the abnormality occurrence position P, when the monitor U2 is selected, the non-monitoring range B1 shown in the upper diagram of FIG. 10 is formed. On the other hand, when the supervisor U3 is selected, a non-monitoring range B2 shown in the lower diagram of FIG. 10 is formed. The supervisor U3 is farther from the abnormality occurrence position P than the supervisor U2. However, the non-monitoring range B2 may be smaller than the non-monitoring range B1. That is, the distribution of the imaging range of the other monitoring person U when the monitoring person U2 deals is more biased than the distribution of the imaging range of the other monitoring person U when the monitoring person U3 deals. Therefore, in this case, if the monitoring person U3 handles the abnormality more than the monitoring person U2, since the distribution of the imaging range by the other monitoring person U is maintained relatively uniform, the disturbance of the monitoring system may be reduced. it can. Therefore, the selection part 113 selects the monitoring person U3.

(2) The selection unit 113 may select the monitoring person U to deal with so that a preset important monitoring point is included in any imaging range other than the monitoring person U dealing with the abnormality. This is because there is a case where it is desired that the important monitoring point does not leak from the imaging range at all. Such points include, for example, important facilities and their surroundings, or points where the degree of crowding of people is likely to increase, such as marathon start points and goal points. Therefore, the selection unit 113 does not select the monitoring staff U whose point that needs to be monitored is included in the imaging range as a monitoring staff to deal with the abnormality. The important monitoring point may be determined in advance. The important monitoring point may be changed with the passage of time, for example, the progress of the event, or may not be changed.

(3) The selection unit 113 may select the monitoring person U in consideration of the movement amount of each monitoring person U other than the monitoring person U. The selection unit 113 obtains the deviation of the distribution of the imaging range of the other monitoring person U (that is, the non-handling person) that occurs when the monitoring person U (that is, the person to deal with) to be dealt with is selected, and calculates the deviation of the distribution. In order to solve the problem, that is, in order to make the distribution uniform, the coping personnel is selected in consideration of the movement amount when the other monitoring person U is moved. Specifically, the selection unit 113 assumes that one monitor U is selected, calculates the movement amount of another monitor U when the one monitor U is dealing with an abnormality, One of the monitoring personnel U is selected as the coping personnel so that the total sum of the movement amounts is minimized or less than a predetermined distance. In this way, it is possible to suppress an increase in the burden on the supervisor U related to the change of the monitoring system. In addition, when the monitor U to be dealt with is selected, the non-monitor range is extracted from the imaging range of the other monitor U, and the movement amount of the other monitor U for minimizing the non-monitor range is considered. Even so, it is the same.

(4) The selection unit 113 may select the monitoring person U in consideration of the type of abnormality that has occurred. It is desirable that the selection unit 113 further selects the monitoring person U in consideration of the duties (an example of roles) of each monitoring person.
For example, when the abnormality that has occurred is an injured person, the selection unit 113 selects a monitoring person U whose mission is “medical relief”. When the abnormality that has occurred is the appearance of a suspicious person, the selection unit 113 selects the monitoring person U whose mission is “security guard”. The type of abnormality may be specified by image analysis, or may be specified by the operator of the monitoring center. The selection unit 113 may determine the number of monitoring personnel to be selected based on the type of abnormality that has occurred.
In addition, the selection method of (1)-(4) mentioned above is only an illustration.

  According to the monitoring system 1 described above, since the monitoring person U to be dealt with is selected in consideration of the monitoring range of each actual monitoring person U, the monitoring person who deals with the abnormality while reducing the influence on the original monitoring system. U can be selected. Moreover, according to the monitoring system 1, it is possible to prevent the monitoring system from becoming too short even when the selected monitoring person U is dealing with an abnormality.

The present invention may be implemented in a form different from the above-described embodiment. Moreover, you may combine each of the modification shown below.
It is desirable that the imaging range specified by the imaging range information is closer to the field of view of the monitoring person U. Therefore, in specifying the imaging range, a range that becomes a blind spot may be considered. For example, when a building is included in the imaging range, the back of the building is a blind spot. In addition, the blind spot is behind the area where the degree of congestion is high and people are densely present. The selection unit 113 can also specify an imaging range based on information on a range in which a target that causes a blind spot exists.

The updating unit 114 may sequentially update the monitoring position and the monitoring direction of the monitoring staff in the monitoring system plan. For example, each time the image capturing range information is acquired from the monitor terminal 20, the server device 10 updates the monitoring position and the monitoring direction related to the corresponding monitor in the monitoring system table 141.
In addition, the update unit 114 may change the role of the monitor according to the occurrence state of the abnormality. For example, the updating unit 114 may change the “movement possibility” field of the monitoring system table 141 from “impossible” to “permitted”. For example, the update unit 114 changes the “Moveability” field from “Improper” to “Allowed” when there is a shortage of the monitoring person U whose “Moveability” field is “Available” for the abnormality that has occurred. Change to Moreover, the update part 114 may change the mission of the supervisor U. Thereby, according to the abnormality which generate | occur | produced, the monitoring system can be changed flexibly.

  The notification unit 115 notifies at least one of the monitoring personnel to change the movement or orientation when the imaging ranges of a plurality of monitoring personnel overlap based on the imaging range information even when an abnormality has not occurred. May be. As a result, the monitoring system can be optimized.

  Some of the hardware circuits, functions, or operations described in the above-described embodiments may be omitted. For example, the monitoring system of the present invention may not manage the monitoring system using the monitoring system table 141. In the monitoring system of the present invention, the action performed by the operator may be automated using an artificial intelligence technique. Moreover, the supervisor terminal, the portable terminal, or the operation terminal may have some of the functions that the server device has in the above-described embodiment. Further, the monitoring system of the present invention is not limited to monitoring the place where an event is held, but can be applied to monitoring an arbitrary place such as a public place.

  Each function realized by the monitoring system of the above-described embodiment may be realized by one or a plurality of hardware circuits, may be realized by executing one or a plurality of programs, or a combination thereof. It may be realized. When the function of the monitoring system is realized using a program, the program can be a magnetic recording medium (magnetic tape, magnetic disk (HDD (Hard Disk Drive), FD (Flexible Disk)), etc.), optical recording medium (optical disk, etc.). ), May be provided in a state of being stored in a computer-readable recording medium such as a magneto-optical recording medium or a semiconductor memory, or may be distributed via a network. The present invention can also be grasped as a monitoring method.
