Description

Technical Field

[0001] The present invention relates to a disaster monitoring device, a disaster monitoring system, a disaster monitoring method, and a recording medium, and more particularly to a disaster monitoring device, a disaster monitoring method, and a recording medium for monitoring the occurrence of disasters in a monitoring target area.

Background Art

[0002] In related technologies, the occurrence of disasters is monitored using surveillance cameras and sensor devices. In one example, a large number of surveillance cameras are installed around a river (for example, on a riverbed or a levee). The data of the surveillance videos captured by each surveillance camera is transferred by wireless communication to a monitoring center such as a civil engineering office or a management office.

[0003] The surveillance videos transmitted from the surveillance cameras are displayed on a video monitor in the monitoring center. While looking at the surveillance videos displayed on the video monitor, an operator discovers natural disasters such as increased water levels, external water flooding, internal water flooding, debris flows, levee breaches, or floods in the river, as well as man-made disasters such as illegal dumping. The monitoring system described in Patent Document 1 enables an operator to quickly grasp the monitoring location where a disaster has occurred by displaying map data indicating the monitoring location on a display device together with the surveillance videos.

Modes for Carrying Out the Invention

[0013] One or more embodiments of the present invention will be described below with reference to the drawings.

[0014] (Disaster Monitoring System 1) Referring to FIG. 1, an example of the configuration of a disaster monitoring system 1 including any one of the disaster monitoring devices 10, 20, and 30 according to Embodiments 1 to 3 described below will be first described. In FIG. 1, "disaster monitoring device 10(20, 30)" represents any one of the disaster monitoring devices 10, 20, and 30 according to Embodiments 1 to 3.

[0015] As shown in FIG. 1, the disaster monitoring system 1 includes a monitoring camera 100, a sensor device 100A, a monitoring center 200, a video monitor 300, and a monitoring video recording device 400. Except for the monitoring video recording device 400, each component of the disaster monitoring system 1 may be plural. In particular, the plurality of monitoring cameras 100 and the plurality of sensor devices 100A may be distributed and arranged in disaster risk areas within the monitoring target area. The monitoring target area is an area designated to be monitored by the disaster monitoring system 1. The monitoring target area is designated based on administrative divisions such as prefectures, cities, towns, and villages, for example.

[0016] The monitoring camera 100 is installed in a disaster risk area within the monitoring target area, such as a river or a forest road. The monitoring camera 100 photographs a disaster risk area such as a river or a forest road and generates monitoring video data. For example, the monitoring camera 100 is a general video camera for outdoor use. Alternatively, the monitoring camera 100 may be a street camera, a security camera, or an in-vehicle camera mounted on a public vehicle.

[0017] The monitoring camera 100 can be connected to the Internet through a wireless network. The monitoring camera 100 transmits the monitoring video, together with the identification information of the monitoring camera 100, to the disaster monitoring device 10(20, 30) through the wireless network and the Internet. In addition, real-time monitoring video (live video) may be webcast from the monitoring camera 100.

[0018] The sensor device 100A is also installed in disaster-prone areas within the monitoring target area, such as rivers and forest roads. For example, the sensor device 100A is a general IoT device. The sensor device 100A may be integrated with the monitoring camera 100. The sensor device 100A is, for example, a temperature sensor, a humidity sensor, a snow accumulation sensor, a light sensor, a water level sensor, an acceleration sensor, a gyro sensor, an infrared sensor, a radiation sensor, or a gas detector. The sensor device 100A may be a combination of those exemplified here.

[0019] The sensor device 100A can be connected to the Internet through a wireless network. The sensor device 100A transmits sensor data (for example, data of the measured water level) to the monitoring center 200 and the disaster monitoring devices 10(20, 30) through the wireless network and the Internet.

[0020] The monitoring center 200 is a facility for monitoring the occurrence of disasters within the monitoring target area, such as a civil engineering office or a management office. A video monitor and an alarm (both not shown) are arranged in the monitoring center 200. The monitoring video taken by the monitoring camera 100 is transferred from the disaster monitoring devices 10(20, 30) to the monitoring center 200. Also, real-time monitoring video may be distributed to the monitoring center 200 from the monitoring camera 100 through the Internet.

[0021] The monitoring video received from the disaster monitoring devices 10(20, 30) is displayed on the video monitor of the monitoring center 200. The alarm in the monitoring center 200 receives sensor data from the sensor device 100A. The alarm compares the measured value indicated by the sensor data with a threshold value corresponding to the type of the sensor data. When the measured value exceeds the threshold value, the alarm issues a warning. Alternatively, the alarm may receive a notification from the sensor device 100A when the measured value indicated by the sensor data exceeds the threshold value. In this case, the alarm immediately issues a warning in response to the notification from the sensor device 100A.

[0022] At the monitoring center 200, a monitoring operator monitors disaster risk areas (such as rivers and forest roads) shown in the monitoring video while looking at a video monitor. Also, when the warning device issues a warning, the monitoring operator provides disaster information to disaster prevention organizations such as local governments or warns of the occurrence of a disaster.

[0023] The video monitor 300 is a display device used by a monitoring assistant. The video monitor 300 is an example of a display device corresponding to the monitoring assistant. The monitoring assistant is located at a place away from the monitoring center 200. The monitoring assistant communicates with the monitoring operator at the monitoring center 200 to support the monitoring of disaster risk areas. The monitoring assistant is, for example, a staff member of a local government responsible for the command of a disaster prevention organization.

[0024] The video monitor 300 is connected to the Internet and can communicate with the disaster monitoring devices 10(20, 30) and the monitoring center 200. The monitoring video captured by the monitoring camera 100 is transferred from the disaster monitoring devices 10(20, 30) to the video monitor 300.

[0025] The monitoring video recording device 400 stores the monitoring video received by the disaster monitoring devices 10(20, 30) from the monitoring camera 100. Also, the identification information of the monitoring camera 100 that captured the monitoring video is linked to the monitoring video and stored in the monitoring video recording device 400.

[0026] The disaster monitoring devices 10, 20, 30 will be described in Embodiments 1 to 3 described later.

[0027] 〔Embodiment 1〕 Referring to FIGS. 2 to 3, Embodiment 1 will be described.

[0028] (Disaster Monitoring Device 10) Referring to FIG. 2, the configuration of the disaster monitoring device 10 according to the present Embodiment 1 will be described. FIG. 2 is a block diagram showing the configuration of the disaster monitoring device 10. As shown in FIG. 2, the disaster monitoring device 10 includes an acquisition unit 11, a selection unit 12, and a transfer unit 13.

[0029] The acquisition unit 11 acquires information regarding the occurrence of a disaster or the prediction of the occurrence of a disaster within the area to be monitored. The acquisition unit 11 is an example of acquisition means. Information regarding the occurrence of a disaster or the prediction of the occurrence of a disaster within the area to be monitored includes at least information indicating that a disaster has occurred within the area to be monitored (e.g., a meteorological warning) and information indicating that it is predicted that a disaster will occur within the area to be monitored (e.g., an earthquake early warning).

[0030] In one example, the acquisition unit 11 receives sensor data (e.g., data of a measured water level) from the sensor device 100A (FIG. 1) through a wireless network and the Internet. The acquisition unit 11 compares the measured value indicated by the sensor data with a threshold value corresponding to the type of the sensor data.

[0031] The acquisition unit 11 acquires, as information regarding the prediction of the occurrence of a disaster, that the measured value (e.g., the water level) has exceeded a first threshold value. Further, the acquisition unit 11 acquires, as information indicating the occurrence of a disaster, that the measured value has exceeded a second threshold value that is larger than the first threshold value.

[0032] The acquisition unit 11 notifies the selection unit 12 that it has acquired information regarding the occurrence of a disaster or the prediction of the occurrence of a disaster within the area to be monitored.

[0033] After information regarding the occurrence of a disaster or the prediction of the occurrence of a disaster within the area to be monitored is acquired, the selection unit 12 selects one or a plurality of monitoring videos among the monitoring videos monitored by the monitoring operator. The selection unit 12 is an example of selection means.

[0034] In one example, the selection unit 12 is notified by the acquisition unit 11 that it has acquired information regarding the occurrence of a disaster or the prediction of the occurrence of a disaster within the area to be monitored. After receiving the notification from the acquisition unit 11, the selection unit 12 selects one or a plurality of monitoring videos among the monitoring videos monitored by the monitoring operator.

[0035] For example, the selection unit 12 selects a surveillance video captured at a location close to the surveillance assistant from among a plurality of surveillance videos monitored by the surveillance operator of the surveillance center 200.

[0036] In this example, the selection unit 12 acquires the identification information of the surveillance camera 100 associated with the surveillance video from the surveillance video recording device 400 (FIG. 1). Further, the selection unit 12 refers to a map database (not shown) indicating the position of the surveillance camera 100. Then, the selection unit 12 specifies the position of the surveillance camera 100 based on the identification information of the surveillance camera 100.

[0037] Next, the selection unit 12 specifies the position of the surveillance assistant (i.e., the position of the video monitor 300). The position information of the surveillance assistant may be stored in advance in the above-mentioned map database. The selection unit 12 measures the distance from the position of the surveillance assistant to the position of the surveillance camera 100 that captured the surveillance video. Then, the selection unit 12 selects a surveillance video captured at the location closest to the position of the surveillance assistant from among the plurality of surveillance videos.

[0038] In another example, the selection unit 12 selects a surveillance video captured in the area where disaster prevention meteorological information is announced from among the surveillance videos monitored by the surveillance operator. The disaster prevention meteorological information is forecasts and information related to meteorology, earthquakes, volcanoes, etc., and is, for example, a meteorological warning, a meteorological caution, or an earthquake early warning.

[0039] In this example, the selection unit 12 collects disaster prevention meteorological information published on the Internet. The selection unit 12 specifies the area where the disaster prevention meteorological information is announced. Then, the selection unit 12 selects a surveillance video captured within the area where the disaster prevention meteorological information is announced from among the plurality of surveillance videos. Note that the selection unit 12 may select one or a plurality of surveillance videos based on the rank (importance) of the surveillance camera 100 or the surveillance video.

[0040] The selection unit 12 outputs the selected one or a plurality of surveillance videos to the transfer unit 13.

[0041] The transfer unit 13 transfers the selected one or more surveillance videos to a display device corresponding to the surveillance assistant. The transfer unit 13 is an example of transfer means.

[0042] In one example, the transfer unit 13 receives one or more surveillance videos selected by the selection unit 12 from the selection unit 12. The transfer unit 13 transfers the received one or more surveillance videos to the video monitor 300 (FIG. 1) used by the surveillance assistant via the Internet.

[0043] The transfer unit 13 may transmit the one or more surveillance videos received from the selection unit 12 to the video monitor 300 used by the surveillance assistant when a certain condition is satisfied. For example, when the number of surveillance videos taken in the disaster prevention weather information announcement area among the surveillance videos monitored by the surveillance executor exceeds a threshold, the transfer unit 13 transfers the selected surveillance videos to the display device corresponding to the surveillance assistant. This is because as the number of surveillance videos taken in the disaster prevention weather information announcement area increases, the surveillance executor needs to pay attention to several surveillance videos, so the mental or physical burden increases.

[0044] When there are multiple candidates for the surveillance assistant, the transfer unit 13 may determine, as the surveillance assistant, a candidate for the surveillance assistant who is suitable for monitoring the selected one or more surveillance videos. For example, the transfer unit 13 determines the surveillance assistant according to the priority order among a plurality of predetermined candidates for the surveillance assistant. This priority order may be determined according to how much burden the candidate for the surveillance assistant can bear (the level of burden capacity), such as the smallness of the load currently imposed on the candidate for the surveillance assistant. One or more specific examples other than the above examples will be described in Embodiment 2 and Embodiment 3 described later.

[0045] (Operation of the disaster monitoring device 10) Referring to FIG. 3, the operation of the disaster monitoring device 10 according to the first embodiment will be described. FIG. 3 is a flowchart showing the flow of processing executed by each part of the disaster monitoring device 10.

[0046] As shown in FIG. 3, the acquisition unit 11 acquires information regarding the occurrence of a disaster or the prediction of the occurrence of a disaster within the area to be monitored (S1). The acquisition unit 11 notifies the selection unit 12 that it has acquired information regarding the occurrence of a disaster or the prediction of the occurrence of a disaster within the area to be monitored.

[0047] After information regarding the occurrence of a disaster or the prediction of the occurrence of a disaster within the area to be monitored is acquired, the selection unit 12 selects one or more monitoring videos from among the monitoring videos monitored by the monitor (S2). The selection unit 12 outputs the selected one or more monitoring videos to the transfer unit 13.

[0048] The transfer unit 13 transfers the selected one or more monitoring videos to the display device corresponding to the monitoring assistant (S3). Specifically, the transfer unit 13 transfers some of the monitoring videos monitored by the monitor to the video monitor 300 (FIG. 1) used by the monitoring assistant.

[0049] Thus, the operation of the disaster monitoring device 10 according to the first embodiment ends.

[0050] (Effect of this embodiment) According to the configuration of this embodiment, the acquisition unit 11 acquires information regarding the occurrence of a disaster or the prediction of the occurrence of a disaster within the area to be monitored. After information regarding the occurrence of a disaster or the prediction of the occurrence of a disaster within the area to be monitored is acquired, the selection unit 12 selects one or more monitoring videos from among the monitoring videos monitored by the monitor. The transfer unit 13 transfers the selected one or more monitoring videos to the display device corresponding to the monitoring assistant.

[0051] After information regarding the occurrence of a disaster or the prediction of the occurrence of a disaster within the area to be monitored is acquired, the monitor needs to continuously focus on the monitoring video, so the physical and mental burden is large. At this time, one or more monitoring videos among the monitoring videos monitored by the monitor are selected and transferred to the display device corresponding to the monitoring assistant. Thereby, monitoring can be shared between the monitor and the monitoring assistant, so that the burden of monitoring based on the monitoring video can be reduced.

[0052] 〔Embodiment 2〕 Referring to FIGS. 4 to 5, Embodiment 2 will be described. In this Embodiment 2, components that execute the same processing as the components described in Embodiment 1 are given the same reference numerals as in Embodiment 1, and the description of those components will be omitted.

[0053] In this Embodiment 2, an example of a configuration for determining, as a monitoring assistant, a candidate for a monitoring assistant who is suitable for monitoring one or more selected monitoring videos according to the type of disaster when there are a plurality of candidates for the monitoring assistant will be described.

[0054] In this Embodiment 2, it is assumed that the disaster monitoring system 1 (FIG. 1) includes a plurality of video monitors 300 according to the number of candidates for the monitoring assistant in response to there being a plurality of candidates for the monitoring assistant.

[0055] (Disaster monitoring device 20) Referring to FIG. 4, the configuration of the disaster monitoring device 20 according to this Embodiment 2 will be described. FIG. 4 is a block diagram showing the configuration of the disaster monitoring device 20. As shown in FIG. 4, the disaster monitoring device 20 includes an acquisition unit 11, a selection unit 12, and a transfer unit 13'. The transfer unit 13' of the disaster monitoring device 20 is partially different from the transfer unit 13 of the disaster monitoring device 10 according to Embodiment 1 in the content of the processing it executes. The processing executed by the transfer unit 13' will be described below.

[0056] Similar to the transfer unit 13, the transfer unit 13' transfers one or more monitoring videos selected by the selection unit 12 to a display device corresponding to the monitoring assistant. At this time, the transfer unit 13' determines the type of disaster that has occurred or is predicted to occur within the monitoring target area.

[0057] The acquisition unit 11 notifies the selection unit 12 that it has acquired information regarding the occurrence or prediction of the occurrence of a disaster within the monitoring target area, and outputs information indicating the type of disaster to the transfer unit 13'.

[0058] Similar to the transfer unit 13, the transfer unit 13' receives one or more selected surveillance videos from the selection unit 12. Also, the transfer unit 13' receives information indicating the type of disaster from the acquisition unit 11.

[0059] The transfer unit 13' determines a surveillance assistant from among a plurality of candidates for surveillance assistants, and transfers the surveillance videos selected by the selection unit 12 to the display device corresponding to the determined surveillance assistant.

[0060] Specifically, when the disaster is an earthquake, a tsunami, or a high tide, the transfer unit 13' determines a candidate for a surveillance assistant who is far from the surveillance target area as the surveillance assistant. On the other hand, when the disaster is a river flood, the transfer unit 13' determines a candidate for a surveillance assistant who is close to the surveillance target area as the surveillance assistant.

[0061] Here, the identification information of the video monitor 300 used by the candidate for the surveillance assistant may be stored in advance in the map database described in the first embodiment. The transfer unit 13' can identify the video monitor 300 used by the determined surveillance assistant by referring to the map database.

[0062] Thereafter, the transfer unit 13' transfers one or more surveillance videos selected by the selection unit 12 to the video monitor 300 (FIG. 1) used by the determined surveillance assistant.

[0063] (Modification example) In one modification example, the transfer unit 13' may transmit information indicating one or more surveillance videos selected by the selection unit 12, together with all the surveillance videos monitored by the surveillance operator, to the video monitor 300 used by the surveillance assistant. The transfer unit 13' causes all the surveillance videos monitored by the surveillance operator to be displayed on the display screen of the video monitor 300, and only the one or more surveillance videos selected by the selection unit 12 are highlighted, for example, by surrounding them with a red frame.

[0064] According to the configuration of this modification example, since only the one or more surveillance videos selected by the selection unit 12 are highlighted, those surveillance videos can be made to be watched by the surveillance assistant.

[0065] (Operation of Disaster Monitoring Device 20) With reference to FIG. 5, the operation of the disaster monitoring device 20 according to the second embodiment will be described. FIG. 5 is a flowchart showing the flow of processes executed by each part of the disaster monitoring device 20.

[0066] As shown in FIG. 5, the acquisition unit 11 acquires information regarding the occurrence or predicted occurrence of a disaster within the monitoring target area (S201). The acquisition unit 11 notifies the selection unit 12 that it has acquired information regarding the occurrence or predicted occurrence of a disaster within the monitoring target area. Further, the acquisition unit 11 outputs information indicating the type of the disaster to the transfer unit 13'.

[0067] After information regarding the occurrence or predicted occurrence of a disaster within the monitoring target area is acquired, the selection unit 12 selects one or more monitoring videos out of the monitoring videos monitored by the monitoring executor (S202). The selection unit 12 outputs the selected one or more monitoring videos to the transfer unit 13'.

[0068] Based on the information indicating the type of the disaster, the transfer unit 13' determines the type of the disaster that has occurred or is predicted to occur (S203).

[0069] In step S203, the transfer unit 13' classifies the disaster that has occurred or is predicted to occur into one of one or more types (for example, earthquake, tsunami, high tide, river flooding). Here, the transfer unit 13' classifies the type of the disaster into either type A including earthquake, tsunami, and high tide or type B including river flooding (external water flooding, internal water flooding).

[0070] When the disaster is an earthquake, a tsunami, or a high tide (type A in S203), the transfer unit 13' determines candidates for monitoring assistants who are away from the monitoring target area as the monitoring assistants (S204A). On the other hand, when the disaster is a river flooding (type B in S203), the transfer unit 13' determines candidates for monitoring assistants who are close to the monitoring target area as the monitoring assistants (S204B).

[0071] The transfer unit 13' transfers the selected one or more surveillance videos to the display device corresponding to the surveillance assistant (S205). Specifically, the transfer unit 13' transfers some of the surveillance videos monitored by the surveillance operator to the video monitor 300 (FIG. 1) used by the surveillance assistant.

[0072] Thus, the operation of the disaster surveillance device 20 according to the second embodiment ends.

[0073] (Effect of this embodiment) According to the configuration of this embodiment, the acquisition unit 11 acquires information regarding the occurrence or predicted occurrence of a disaster within the surveillance target area. After information regarding the occurrence or predicted occurrence of a disaster within the surveillance target area is acquired, the selection unit 12 selects one or more surveillance videos from among the surveillance videos monitored by the surveillance operator. The transfer unit 13' transfers the selected one or more surveillance videos to the display device corresponding to the surveillance assistant.

[0074] After information regarding the occurrence or predicted occurrence of a disaster within the surveillance target area is acquired, the surveillance operator needs to continue to focus on the surveillance videos, so the physical and mental burden is large. At this time, one or more surveillance videos from among the surveillance videos monitored by the surveillance operator are selected and transferred to the display device corresponding to the surveillance assistant. Thereby, since the surveillance can be shared between the surveillance operator and the surveillance assistant, the burden of surveillance based on the surveillance videos can be reduced.

[0075] Furthermore, according to the configuration of the present embodiment, when the disaster is an earthquake, a tsunami, or a high tide, the transfer unit 13' determines a candidate for a monitoring assistant who is away from the area to be monitored as the monitoring assistant. This is because the farther the monitoring assistant is from the site of a disaster such as an earthquake, the lower the possibility that the monitoring assistant will be affected by a secondary disaster. On the other hand, when the disaster is a river flood, the transfer unit 13' determines a candidate for a monitoring assistant who is close to the area to be monitored as the monitoring assistant. This is because the closer the monitoring assistant is to the river, the easier it is for the monitoring assistant to respond to the site of emergency civil engineering work or the like. In this way, by determining an appropriate monitoring assistant from among a plurality of candidates for the monitoring assistant according to the type of disaster, the monitoring assistant can more reliably monitor the occurrence of the disaster.

[0076] 〔Embodiment 3〕 Referring to FIG. 6, Embodiment 3 will be described. In this Embodiment 3, components that execute the same processing as the components described in the above Embodiment 1 or Embodiment 2 are given the same reference numerals as in Embodiment 1 or Embodiment 2, and the description of those components is omitted.

[0077] In this Embodiment 3, an example of a configuration for defining the conditions for entrusting a monitoring assistant will be described.

[0078] (Disaster monitoring device 30) The configuration of the disaster monitoring device 30 according to this Embodiment 3 is the same as the configuration of the disaster monitoring device 20 (FIG. 4) according to the above Embodiment 2. However, the transfer unit 13' of the disaster monitoring device 30 is partly different from the transfer unit 13' of the disaster monitoring device 20 according to the above Embodiment 2 in the content of the processing it executes.

[0079] Similar to the transfer unit 13, the transfer unit 13' transfers the selected one or more monitoring videos to the display device corresponding to the monitoring assistant. At this time, the transfer unit 13' determines the magnitude of the monitoring burden.

[0080] The acquisition unit 11 notifies the selection unit 12 that it has acquired information regarding the occurrence or predicted occurrence of a disaster within the area to be monitored, and outputs information indicating the type of the disaster to the transfer unit 13'.

[0081] Similar to the transfer unit 13, the transfer unit 13' receives one or more selected surveillance videos from the selection unit 12. Also, the transfer unit 13' receives information indicating the type of disaster from the acquisition unit 11.

[0082] The transfer unit 13' determines a surveillance assistant from among a plurality of candidates for surveillance assistants, and transfers the surveillance videos selected by the selection unit 12 to the display device corresponding to the determined surveillance assistant.

[0083] Specifically, when the number of surveillance videos taken in the announcement area of disaster prevention weather information (such as weather warnings, weather advisories, earthquake early warnings, etc.) among the surveillance videos monitored by the surveillance operator exceeds a threshold value, the transfer unit 13' transfers the selected surveillance videos to the display device corresponding to the surveillance assistant. The threshold value is set in advance according to the experience, ability, duties, etc. of the surveillance operator.

[0084] For example, the transfer unit 13' refers to the map database described in the first and second embodiments to confirm the position of the surveillance camera 100. The transfer unit 13' determines whether the surveillance video was taken in the announcement area of disaster prevention weather information based on the announcement area of disaster prevention weather information and the position of the surveillance camera 100. For each of the surveillance videos monitored by the surveillance operator, the transfer unit 13' performs the above determination. Based on the above determination results, the transfer unit 13' calculates the number of surveillance videos taken in the announcement area of disaster prevention weather information among the surveillance videos monitored by the surveillance operator. Triggered by the fact that the number of surveillance videos taken in the announcement area of disaster prevention weather information exceeds the threshold value, the transfer unit 13' executes the process of transferring the surveillance videos to the display device corresponding to the surveillance assistant.

[0085] (Operation of the disaster monitoring device 30) Referring to FIG. 6, the operation of the disaster monitoring device 30 according to the third embodiment will be described. FIG. 6 is a flowchart showing the flow of processes executed by each part of the disaster monitoring device 30.

[0086] As shown in FIG. 6, the acquisition unit 11 acquires information regarding the occurrence or predicted occurrence of a disaster within the area to be monitored (S301). The acquisition unit 11 notifies the selection unit 12 that it has acquired information regarding the occurrence or predicted occurrence of a disaster within the area to be monitored. Further, the acquisition unit 11 outputs information indicating the type of disaster to the transfer unit 13'.

[0087] After the selection unit 12 acquires information regarding the occurrence or predicted occurrence of a disaster within the area to be monitored, the selection unit 12 selects one or more of the monitoring videos monitored by the monitoring operator (S302). The selection unit 12 outputs the selected one or more monitoring videos to the transfer unit 13'.

[0088] The transfer unit 13' determines whether the number of monitoring videos taken in the area where disaster prevention weather information is announced exceeds a threshold value (S203).

[0089] If the number of monitoring videos taken in the area where disaster prevention weather information is announced exceeds the threshold value (Yes in S203), the transfer unit 13' transfers the selected one or more monitoring videos to the display device corresponding to the monitoring assistant (S304). Specifically, the transfer unit 13' transfers some of the monitoring videos monitored by the monitoring operator to the video monitor 300 (FIG. 1) used by the monitoring assistant.

[0090] Thus, the operation of the disaster monitoring device 30 according to the third embodiment ends.

[0091] (Effect of this embodiment) According to the configuration of this embodiment, the acquisition unit 11 acquires information regarding the occurrence or predicted occurrence of a disaster within the area to be monitored. After the selection unit 12 acquires information regarding the occurrence or predicted occurrence of a disaster within the area to be monitored, the selection unit 12 selects one or more of the monitoring videos monitored by the monitoring operator. The transfer unit 13' transfers the selected one or more monitoring videos to the display device corresponding to the monitoring assistant.

[0092] After information regarding the occurrence or predicted occurrence of a disaster within the area to be monitored is obtained, the monitor must continue to watch the surveillance videos, which places a significant physical and mental burden on them. At this time, one or more of the surveillance videos being monitored by the monitor are selected and transferred to the display device corresponding to the surveillance assistant. As a result, the monitoring can be shared between the monitor and the surveillance assistant, thus reducing the burden of monitoring based on the surveillance videos.

[0093] Furthermore, according to the configuration of the present embodiment, when the number of surveillance videos taken within the disaster prevention weather information announcement area among the surveillance videos monitored by the monitor exceeds the threshold, the transfer unit 13' transfers the selected surveillance videos to the display device corresponding to the surveillance assistant. As a result, the assistance of monitoring can be entrusted before the burden of monitoring becomes too large in relation to the experience, ability, etc. of the monitor.
