Description

The present invention relates to a disaster monitoring device, a disaster monitoring system, a disaster monitoring method, and a recording medium, and in particular to a disaster monitoring device, a disaster monitoring method, and a recording medium for monitoring the occurrence of disasters within a monitored area.

In a related technology, surveillance cameras and sensor devices are used to monitor the occurrence of disasters. In one example, a large number of surveillance cameras are installed around a river (e.g., on the riverbed or on the levee). The surveillance video data captured by each surveillance camera is transferred via wireless communication to a monitoring center such as a civil engineering office or management office.

Video monitors in the monitoring center display surveillance footage transmitted from surveillance cameras. While viewing the surveillance footage displayed on the video monitors, operators can detect natural disasters such as rising river levels, external flooding, internal flooding, debris flow, levee collapse, and flooding, as well as man-made disasters such as illegal dumping. The monitoring system described in Patent Document 1 displays map data showing the monitoring location on a display device along with the surveillance footage, enabling operators to quickly identify the monitoring location where a disaster has occurred.

Japanese Patent Application Publication No. 11-102495

Typically, multiple surveillance footage captured by multiple surveillance cameras is displayed at once on a video monitor at a monitoring center. Operators must continue to monitor multiple surveillance footage for long periods of time. There is a need for a mechanism to reduce the burden of monitoring based on surveillance footage so that operators do not miss natural disasters.

The present invention has been made in consideration of the above problems, and its purpose is to reduce the burden of surveillance based on surveillance footage.

A disaster monitoring device according to one embodiment of the present invention includes an acquisition means for acquiring information regarding the occurrence of a disaster or the prediction of a disaster occurring within a monitored area, a selection means for selecting one or more surveillance images from the surveillance images monitored by the surveillance performer after the information regarding the occurrence of a disaster or the prediction of a disaster occurring within the monitored area has been acquired, and a transfer means for transferring the selected one or more surveillance images to a display device corresponding to a surveillance assistant.

In one embodiment of the disaster monitoring method of the present invention, a computer acquires information regarding the occurrence of a disaster or a prediction of a disaster occurring within a monitored area, and after the information regarding the occurrence of a disaster or a prediction of a disaster occurring within the monitored area has been acquired, the computer selects one or more surveillance images from the surveillance images monitored by the surveillance performer, and transfers the selected one or more surveillance images to a display device corresponding to the surveillance assistant.

A recording medium according to one embodiment of the present invention stores a program for causing a computer to obtain information relating to the occurrence of a disaster or the prediction of a disaster occurring within a monitored area, select one or more surveillance images from among the surveillance images monitored by the surveillance performer after the information relating to the occurrence of a disaster or the prediction of a disaster occurring within the monitored area has been obtained, and transfer the selected one or more surveillance images to a display device corresponding to the surveillance assistant.

One or more embodiments of the present invention are described below with reference to the drawings.

(Disaster monitoring system 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 the first to third embodiments will be described first with reference to Fig. 1. In Fig. 1, "disaster monitoring device 10 (20, 30)" refers to any one of the disaster monitoring devices 10, 20, and 30 according to the first to third embodiments.

As shown in FIG. 1, the disaster monitoring system 1 includes a surveillance camera 100, a sensor device 100A, a monitoring center 200, a video monitor 300, and a surveillance video recording device 400. There may be more than one of each component of the disaster monitoring system 1, except for the surveillance video recording device 400. In particular, the multiple surveillance cameras 100 and the multiple sensor devices 100A may be distributed and placed in disaster risk areas within the monitored area. The monitored area is an area designated to be monitored by the disaster monitoring system 1. The monitored area is designated based on administrative districts such as prefectures and cities, towns, and villages, for example.

The surveillance camera 100 is installed in disaster danger areas within a monitored area, such as rivers and forest roads. The surveillance camera 100 captures images of disaster danger areas, such as rivers and forest roads, and generates surveillance video data. For example, the surveillance camera 100 is a general-purpose video camera for outdoor use. Alternatively, the surveillance camera 100 may be a street camera, a security camera, or an on-board camera mounted on a public vehicle.

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

The sensor device 100A is also installed in disaster-prone areas within the monitored 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 surveillance camera 100. The sensor device 100A is, for example, a temperature sensor, a humidity sensor, a snow 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 the examples given here.

The sensor device 100A can be connected to the Internet via a wireless network. The sensor device 100A transmits sensor data (e.g., water level measurement data) to the monitoring center 200 and the disaster monitoring device 10 (20, 30) via the wireless network and the Internet.

The monitoring center 200 is a facility such as a civil engineering office or management office for monitoring the occurrence of disasters within a monitored area. Video monitors and alarms (neither shown) are installed in the monitoring center 200. Surveillance footage captured by the surveillance camera 100 is transferred to the monitoring center 200 from the disaster monitoring device 10 (20, 30). In addition, real-time surveillance footage may be distributed to the monitoring center 200 from the surveillance camera 100 via the Internet.

The video monitor of the monitoring center 200 displays the monitoring footage received from the disaster monitoring device 10 (20, 30). The alarm of the monitoring center 200 receives sensor data from the sensor device 100A. The alarm compares the measurement value indicated by the sensor data with a threshold value according to the type of sensor data. If the measurement value exceeds the threshold value, the alarm sounds an alarm. Alternatively, the alarm may receive a notification from the sensor device 100A when the measurement value indicated by the sensor data exceeds the threshold value. In this case, the alarm immediately sounds an alarm in response to the notification from the sensor device 100A.

At the monitoring center 200, the monitoring executor watches the video monitor and monitors disaster danger areas (i.e. rivers, forest roads, etc.) shown on the monitoring footage. When the alarm goes off, the monitoring executor provides disaster information to disaster prevention organizations such as local governments or warns of the occurrence of a disaster.

The video monitor 300 is a display device used by the monitoring assistant. The video monitor 300 is an example of a display device corresponding to the monitoring assistant. The monitoring assistant is located away from the monitoring center 200. The monitoring assistant contacts the monitoring executor at the monitoring center 200 and supports the monitoring of disaster-prone areas. The monitoring assistant is, for example, a local government employee in charge of directing a disaster prevention organization.

The video monitor 300 is connected to the Internet and can communicate with the disaster monitoring device 10 (20, 30) and the monitoring center 200. The video monitor 300 receives surveillance footage captured by the surveillance camera 100 from the disaster monitoring device 10 (20, 30).

The surveillance video recording device 400 stores the surveillance video received by the disaster monitoring device 10 (20, 30) from the surveillance camera 100. The surveillance video recording device 400 also stores the identification information of the surveillance camera 100 that captured the surveillance video, linked to the surveillance video.

The disaster monitoring devices 10, 20, and 30 will be described in embodiments 1 to 3 below.

[Embodiment 1]
The first embodiment will be described with reference to FIGS.

(Disaster monitoring device 10)
The configuration of the disaster monitoring device 10 according to the first embodiment will be described with reference to Fig. 2. 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.

The acquisition unit 11 acquires information regarding the occurrence of a disaster or the prediction of a disaster occurring within the monitored area. The acquisition unit 11 is an example of an acquisition means. The information regarding the occurrence of a disaster or the prediction of a disaster occurring within the monitored area includes at least information indicating that a disaster has occurred within the monitored area (e.g., a weather warning) and information indicating that a disaster is predicted to occur within the monitored area (e.g., an earthquake alert).

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

The acquisition unit 11 acquires information regarding the prediction of the occurrence of a disaster when a measurement value (e.g., water level) exceeds a first threshold. The acquisition unit 11 also acquires information indicating the occurrence of a disaster when a measurement value exceeds a second threshold value that is greater than the first threshold.

The acquisition unit 11 notifies the selection unit 12 that information regarding the occurrence of a disaster or the prediction of the occurrence of a disaster within the monitored area has been acquired.

After acquiring information about the occurrence of a disaster or the prediction of the occurrence of a disaster in the monitored area, the selection unit 12 selects one or more surveillance images from among the surveillance images monitored by the surveillance performer. The selection unit 12 is an example of a selection means.

In one example, the selection unit 12 is notified by the acquisition unit 11 that information regarding the occurrence of a disaster or the prediction of the occurrence of a disaster in the monitored area has been acquired. After receiving the notification from the acquisition unit 11, the selection unit 12 selects one or more surveillance videos from among the surveillance videos monitored by the surveillance performer.

For example, the selection unit 12 selects surveillance footage shot at a location close to the assistant monitor from among multiple surveillance footage monitored by the monitoring performer at the monitoring center 200.

In this example, the selection unit 12 acquires identification information of the surveillance camera 100 linked to the surveillance video from the surveillance video recording device 400 (Figure 1). The selection unit 12 also refers to a map database (not shown) indicating the position of the surveillance camera 100. The selection unit 12 then identifies the position of the surveillance camera 100 based on the identification information of the surveillance camera 100.

Next, the selection unit 12 identifies the position of the monitoring assistant (i.e., the position of the video monitor 300). The position information of the monitoring assistant may be stored in advance in the map database described above. The selection unit 12 measures the distance from the position of the monitoring assistant to the position of the surveillance camera 100 that captured the surveillance footage. Then, from among the multiple surveillance footage, the selection unit 12 selects the surveillance footage that was captured at the location closest to the position of the monitoring assistant.

In another example, the selection unit 12 selects, from among the surveillance footage monitored by the surveillance executor, surveillance footage captured in an area in which disaster prevention weather information is issued. Disaster prevention weather information is forecasts and information related to weather, earthquakes, volcanoes, etc., such as weather warnings, weather advisories, or earthquake alerts.

In this example, the selection unit 12 collects disaster prevention weather information published on the Internet. The selection unit 12 identifies the area for which the disaster prevention weather information is to be announced. Then, the selection unit 12 selects, from among the multiple surveillance videos, surveillance videos taken within the area for which the disaster prevention weather information is to be announced. Note that the selection unit 12 may select one or multiple surveillance videos based on the rank (importance) of the surveillance camera 100 or the surveillance video.

The selection unit 12 outputs the selected surveillance video or videos to the transfer unit 13.

The transfer unit 13 transfers the selected surveillance video or videos to a display device corresponding to the surveillance assistant. The transfer unit 13 is an example of a transfer means.

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

When a certain condition is satisfied, the transfer unit 13 may transmit one or more surveillance images received from the selection unit 12 to the video monitor 300 used by the assistant monitor. For example, when the number of surveillance images captured in the area where disaster prevention weather information is announced among the surveillance images monitored by the monitor exceeds a threshold, the transfer unit 13 transfers the selected surveillance images to the display device corresponding to the assistant monitor. This is because the more surveillance images captured in the area where disaster prevention weather information is announced, the greater the mental or physical burden on the monitor, since the monitor needs to focus on several surveillance images.

When there are multiple candidates for a monitoring assistant, the transfer unit 13 may determine the monitoring assistant candidate who is suitable for monitoring the selected one or more surveillance videos. For example, the transfer unit 13 determines the monitoring assistant according to a priority order among multiple predetermined monitoring assistant candidates. This priority order may be determined according to how much burden the monitoring assistant candidate can withstand (the level of burden capacity), such as how light the load currently placed on the monitoring assistant candidate is. One or more specific examples other than the above examples will be described in the second and third embodiments described below.

(Operation of the disaster monitoring device 10)
The operation of the disaster monitoring device 10 according to the first embodiment will be described with reference to Fig. 3. Fig. 3 is a flow chart showing the flow of processes executed by each unit of the disaster monitoring device 10.

As shown in Figure 3, the acquisition unit 11 acquires information regarding the occurrence of a disaster or the prediction of a disaster occurring in the monitored area (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 a disaster occurring in the monitored area.

After acquiring information about the occurrence of a disaster or the prediction of the occurrence of a disaster in the monitored area, the selection unit 12 selects one or more surveillance videos from among the surveillance videos monitored by the surveillance performer (S2). The selection unit 12 outputs the selected one or more surveillance videos to the transfer unit 13.

The transfer unit 13 transfers the selected one or more surveillance images to a display device corresponding to the assistant monitor (S3). Specifically, the transfer unit 13 transfers some of the surveillance images monitored by the surveillance performer to a video monitor 300 (FIG. 1) used by the assistant monitor.

This completes the operation of the disaster monitoring device 10 of this embodiment 1.

(Effects 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 a disaster in a monitored area. After the information regarding the occurrence of a disaster or the prediction of a disaster in a monitored area is acquired, the selection unit 12 selects one or more surveillance videos from among the surveillance videos monitored by the surveillance performer. The transfer unit 13 transfers the selected one or more surveillance videos to a display device corresponding to the surveillance assistant.

After obtaining information about the occurrence or prediction of a disaster in the monitored area, the surveillance executor must continue to watch the surveillance footage, which places a heavy physical and mental burden on the surveillance executor. At this time, one or more surveillance images are selected from the surveillance images monitored by the surveillance executor and are transferred to the display device corresponding to the assistant surveillance. This allows the surveillance responsibilities to be shared between the surveillance executor and the assistant surveillance, thereby reducing the burden of surveillance based on the surveillance footage.

[Embodiment 2]
A second embodiment will be described with reference to Figures 4 and 5. In the second embodiment, the same reference numerals as those in the first embodiment are used for components that execute the same processes as those in the first embodiment, and descriptions of those components will be omitted.

In this embodiment 2, when there are multiple candidates for monitoring assistants, an example of a configuration is described in which a candidate for monitoring assistant suitable for monitoring one or more selected surveillance footage depending on the type of disaster is selected as the monitoring assistant.

In this embodiment 2, the disaster monitoring system 1 (Figure 1) is equipped with multiple video monitors 300 in accordance with the number of candidates for monitoring assistants, in response to the presence of multiple candidates for monitoring assistants.

(Disaster monitoring device 20)
The configuration of the disaster monitoring device 20 according to the second embodiment will be described with reference to Fig. 4. 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 partially differs from the transfer unit 13 of the disaster monitoring device 10 according to the first embodiment in the content of the processing it executes. The processing executed by the transfer unit 13' will be described below.

The transfer unit 13', like the transfer unit 13, transfers one or more surveillance images selected by the selection unit 12 to a display device corresponding to the assistant monitor. At this time, the transfer unit 13' determines the type of disaster that has occurred or is predicted to occur within the monitored area.

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

The transfer unit 13' receives one or more selected surveillance videos from the selection unit 12, similar to the transfer unit 13. The transfer unit 13' also receives information indicating the type of disaster from the acquisition unit 11.

The transfer unit 13' determines a monitoring assistant from among multiple candidates for monitoring assistants, and transfers the surveillance video selected by the selection unit 12 to a display device corresponding to the determined monitoring assistant.

Specifically, if the disaster is an earthquake, tsunami, or high tide, the transfer unit 13' selects a candidate for a monitoring assistant who is far from the area to be monitored as the monitoring assistant. On the other hand, if the disaster is a river flood, the transfer unit 13' selects a candidate for a monitoring assistant who is close to the area to be monitored as the monitoring assistant.

Here, the identification information of the video monitor 300 used by the candidate for the monitoring 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 to be used by the determined monitoring assistant by referring to the map database.

Then, the transfer unit 13' transfers one or more surveillance images selected by the selection unit 12 to the video monitor 300 (Figure 1) used by the determined surveillance assistant.

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

According to the configuration of this modified example, only one or more surveillance images selected by the selection unit 12 are highlighted, so that the assistant surveillance person can focus on those surveillance images.

(Operation of disaster monitoring device 20)
The operation of the disaster monitoring device 20 according to the second embodiment will be described with reference to Fig. 5. Fig. 5 is a flow chart showing the flow of processes executed by each unit of the disaster monitoring device 20.

As shown in Fig. 5, the acquisition unit 11 acquires information regarding the occurrence of a disaster or the prediction of a disaster occurring in the monitored area (S201). The acquisition unit 11 notifies the selection unit 12 that it has acquired information regarding the occurrence of a disaster or the prediction of a disaster occurring in the monitored area. The acquisition unit 11 also outputs information indicating the type of disaster to the transfer unit 13'.

After acquiring information about the occurrence of a disaster or the prediction of the occurrence of a disaster in the monitored area, the selection unit 12 selects one or more surveillance images from among the surveillance images monitored by the surveillance performer (S202). The selection unit 12 outputs the selected one or more surveillance images to the transfer unit 13'.

The transfer unit 13' determines the type of disaster that has occurred or is predicted to occur based on the information indicating the type of disaster (S203).

In step S203, the transfer unit 13' classifies the disaster that has occurred or is predicted to occur into one or more types (e.g., earthquake, tsunami, storm surge, river flooding). Here, the transfer unit 13' classifies the type of disaster into either type A, which includes earthquakes, tsunamis, and storm surges, or type B, which includes river flooding (external flooding, internal flooding).

If the disaster is an earthquake, tsunami, or high tide (type A in S203), the transfer unit 13' determines the candidate for monitoring assistant who is far from the area to be monitored as the monitoring assistant (S204A). On the other hand, if the disaster is a river flood (type B in S203), the transfer unit 13' determines the candidate for monitoring assistant who is close to the area to be monitored as the monitoring assistant (S204B).

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

This completes the operation of the disaster monitoring device 20 of this embodiment 2.

(Effects 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 a disaster in the monitored area. After the information regarding the occurrence of a disaster or the prediction of a disaster in the monitored area is acquired, the selection unit 12 selects one or more surveillance videos from among the surveillance videos monitored by the surveillance performer. The transfer unit 13' transfers the selected one or more surveillance videos to a display device corresponding to the assistant surveillance performer.

After obtaining information about the occurrence or prediction of a disaster in the monitored area, the surveillance executor must continue to watch the surveillance footage, which places a heavy physical and mental burden on the surveillance executor. At this time, one or more surveillance images are selected from the surveillance images monitored by the surveillance executor and are transferred to the display device corresponding to the assistant surveillance. This allows the surveillance responsibilities to be shared between the surveillance executor and the assistant surveillance, thereby reducing the burden of surveillance based on the surveillance footage.

Furthermore, according to the configuration of this embodiment, when the disaster is an earthquake, tsunami, or high tide, the transfer unit 13' determines a candidate for a monitoring assistant who is far from the area to be monitored as the monitoring assistant. This is because the further the monitoring assistant is from the site of a disaster such as an earthquake, the less likely the monitoring assistant is to 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 closer 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 on-site issues such as emergency civil engineering work. In this way, by determining an appropriate monitoring assistant from among multiple monitoring assistant candidates depending on the type of disaster, the monitoring assistant can more reliably monitor the occurrence of a disaster.

[Embodiment 3]
A third embodiment will be described with reference to Fig. 6. In the third embodiment, components that execute the same processes as those described in the first or second embodiment are denoted by the same reference numerals as those in the first or second embodiment, and descriptions of those components will be omitted.

In this embodiment 3, an example of a configuration for specifying the conditions for entrusting a monitoring assistant is described.

(Disaster monitoring device 30)
The configuration of the disaster monitoring device 30 according to the present embodiment 3 is the same as the configuration of the disaster monitoring device 20 (FIG. 4) according to the above-mentioned embodiment 2. However, the transfer unit 13′ of the disaster monitoring device 30 differs from the transfer unit 13′ of the disaster monitoring device 20 according to the above-mentioned embodiment 2 in part of the contents of the processing executed.

The transfer unit 13' transfers the selected surveillance video or videos to the display device corresponding to the assistant surveillance person, in the same manner as the transfer unit 13. At this time, the transfer unit 13' determines the magnitude of the surveillance burden.

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

The transfer unit 13' receives one or more selected surveillance videos from the selection unit 12, similar to the transfer unit 13. The transfer unit 13' also receives information indicating the type of disaster from the acquisition unit 11.

The transfer unit 13' determines a monitoring assistant from among multiple candidates for monitoring assistants, and transfers the surveillance video selected by the selection unit 12 to a display device corresponding to the determined monitoring assistant.

Specifically, when the number of surveillance images captured in an area where disaster prevention weather information (weather warnings, weather advisories, earthquake alerts, etc.) is issued, among the surveillance images monitored by the surveillance executor, exceeds a threshold value, the transfer unit 13' transfers the selected surveillance images to the display device corresponding to the surveillance assistant. The threshold value is set in advance according to the experience, ability, job duties, etc. of the surveillance executor.

For example, the transfer unit 13' checks the position of the surveillance camera 100 by referring to the map database described in the first and second embodiments. The transfer unit 13' determines whether the surveillance video was taken in the announcement area of the disaster prevention weather information based on the announcement area of the disaster prevention weather information and the position of the surveillance camera 100. The transfer unit 13' performs the above determination for each of the surveillance videos monitored by the surveillance executor. Based on the above determination result, the transfer unit 13' calculates the number of surveillance videos that were taken in the announcement area of the disaster prevention weather information among the surveillance videos monitored by the surveillance executor. When the number of surveillance videos taken in the announcement area of the disaster prevention weather information exceeds a threshold, the transfer unit 13' executes a process of transferring the surveillance video to the display device corresponding to the assistant monitor.

(Operation of disaster monitoring device 30)
The operation of the disaster monitoring device 30 according to the third embodiment will be described with reference to Fig. 6. Fig. 6 is a flow chart showing the flow of processes executed by each unit of the disaster monitoring device 30.

As shown in Fig. 6, the acquisition unit 11 acquires information regarding the occurrence of a disaster or the prediction of a disaster in the monitored area (S301). The acquisition unit 11 notifies the selection unit 12 that it has acquired information regarding the occurrence of a disaster or the prediction of a disaster in the monitored area. The acquisition unit 11 also outputs information indicating the type of disaster to the transfer unit 13'.

After acquiring information about the occurrence of a disaster or the prediction of the occurrence of a disaster in the monitored area, the selection unit 12 selects one or more surveillance images from among the surveillance images monitored by the surveillance performer (S302). The selection unit 12 outputs the selected one or more surveillance images to the transfer unit 13'.

The transfer unit 13' determines whether the number of surveillance images captured in the area where disaster prevention weather information is announced exceeds a threshold value (S203).

If the number of surveillance images taken in the area where disaster prevention weather information is announced exceeds the threshold (Yes in S203), the transfer unit 13' transfers the selected one or more surveillance images to the display device corresponding to the assistant monitor (S304). Specifically, the transfer unit 13' transfers some of the surveillance images monitored by the monitor executor to the video monitor 300 (Figure 1) used by the assistant monitor.

This completes the operation of the disaster monitoring device 30 of this embodiment 3.

(Effects 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 a disaster in the monitored area. After the information regarding the occurrence of a disaster or the prediction of a disaster in the monitored area is acquired, the selection unit 12 selects one or more surveillance videos from among the surveillance videos monitored by the surveillance performer. The transfer unit 13' transfers the selected one or more surveillance videos to a display device corresponding to the assistant surveillance performer.

After obtaining information about the occurrence or prediction of a disaster in the monitored area, the surveillance executor must continue to watch the surveillance footage, which places a heavy physical and mental burden on the surveillance executor. At this time, one or more surveillance images are selected from the surveillance images monitored by the surveillance executor and are transferred to the display device corresponding to the assistant surveillance. This allows the surveillance responsibilities to be shared between the surveillance executor and the assistant surveillance, thereby reducing the burden of surveillance based on the surveillance footage.

Furthermore, according to the configuration of this embodiment, when the number of surveillance images captured in the announcement area of disaster prevention weather information among the surveillance images monitored by the surveillance executor exceeds a threshold, the transfer unit 13' transfers the selected surveillance images to the display device corresponding to the surveillance assistant. This makes it possible to entrust the surveillance assistance before the surveillance burden becomes too great for the surveillance executor's experience, ability, etc.
