Embodiment 1.
FIG. 1 is a diagram showing a configuration example of a disaster response support device according to the first embodiment of the present invention. As shown in FIG. 1, the disaster response support device 1 of the present embodiment is a device that supports emergency response, which is an emergency response, and determines the priority of emergency response and outputs the priority. The generator 2 is provided. The emergency is, for example, the time when a disaster occurs, but is not limited to the time when a disaster occurs, and may be the time when an abnormality that is expected to lead to a disaster occurs. In the following, an emergency will be described by taking as an example a disaster.

The disaster response support device 1 is connected to the sensor information providing device 3 that provides sensor information and the geographical attribute providing device 4 that provides geographical attribute information, respectively, by a communication line. These communication lines may be a wired line or a wireless line, and a wireless line and a wired line may be mixed. Here, an example in which the disaster response support device 1 acquires information from the sensor information providing device 3 and the geographical attribute providing device 4 via a communication line will be described. However, the disaster response support device 1 is a sensor information providing device. The method of acquiring information from the geographical attribute providing device 4 and the geographical attribute providing device 4 is not limited to the example via the communication line. For example, the sensor information providing device 3 may record the sensor information on the recording medium, and the disaster response support device 1 may read the information from the recording medium. Similarly, the geographical attribute information may be provided from the geographical attribute providing device 4 to the disaster response support device 1 via the recording medium.

Further, the sensor information providing device 3 and the geographical attribute providing device 4 may be an external device managed by an administrator other than the organization that operates and manages the disaster response support device 1, or the disaster response support device 1 may be used. It may be a device managed by an organization that operates and manages the device. For example, when the disaster response support device 1 supports disaster response of a plurality of local governments, the sensor information providing device 3 and the geographical attribute providing device 4 are managed by an organization that operates and manages the disaster response support device 1. Obtain sensor information and geographical attribute information over a wide area such as the entire country from an external device. Then, the disaster response support device 1 may acquire the corresponding information from the sensor information providing device 3 and the geographical attribute providing device 4 for each local government to be supported.

The disaster response support device 1 uses sensor information to extract change regions on the surface of the earth, and when there are multiple extracted change regions, the disaster response support device 1 uses sensor information and geographical attribute information to create a plurality of change regions. Determine the priority of each. The change area is a candidate area that is a candidate for an area to be dealt with in an emergency. The surface of the earth includes the surface of land, the surface of the sea, the surface of lakes and rivers, and buildings built on the surface of the earth. Further, the disaster response support device 1 may extract a change region of the atmosphere on the earth. As described above, the sensor information is the information obtained by the observation of the sensor, and is the data acquired by the sensor or the data processed by the data. Further, the sensor information includes information indicating the position of the observation place observed by the sensor. The sensor may be a sensor mounted on an artificial satellite, an aircraft, a drone, or the like, a sensor mounted on a vehicle or the like, or a sensor fixed to the ground surface, a building, or the like.

The sensor may be a passive sensor or an active sensor. Examples of the passive sensor include an image sensor that observes visible light, infrared light, ultraviolet light, and the like. An example of the active sensor is a laser scanner that acquires SAR and three-dimensional point cloud data. The sensor may be a sensor other than these.

Further, the sensor information may be the sensor information of one sensor, or may be a plurality of sensor information corresponding to each of the plurality of sensors. When the disaster response support device 1 uses a plurality of sensor information corresponding to each of the plurality of sensors, the change region is used by using the data obtained by the plurality of sensors in an aligned manner to improve the accuracy. May be extracted. Alternatively, the disaster response support device 1 may acquire from the sensor information providing device 3 that the data obtained by the plurality of sensors are aligned and the accuracy is improved.

Geographical attribute information is information indicating geographical attributes that are attributes for each geographical location such as land use use, population, and road type. That is, the geographical attribute information is information indicating the correspondence between the geographical attribute and the geographical position. The details of the geographical attributes will be described later.

FIG. 2 is a diagram showing a SAR image which is an example of the sensor information of the present embodiment. The SAR image is an image obtained by processing data acquired by SAR mounted on an artificial satellite, an aircraft, or the like. There is known a technique for detecting an area where an abnormality such as a disaster has occurred by using an image acquired by a sensor such as a SAR image. When the change area extracted by using the SAR image is used for a response such as disaster countermeasures, when there are a plurality of change areas, it is desirable to appropriately determine the priority of the response. For example, when an earthquake occurs, even if the value of acceleration measured by a seismograph is large, if the forest is far from the house, it is not necessary to give priority to the response. In addition, since it is considered that elderly people will take time to evacuate, it is desirable to give priority to areas with many elderly people over areas with few elderly people. In addition, there are cases where areas that are judged to have a large impact in the event of a disaster, such as hazard maps, should be given priority over areas that have a small impact. In this embodiment, geographical attributes are used to determine the priority. FIG. 3 is a diagram showing on a map the land use use of the area corresponding to the SAR image of FIG. 2. Land use is an example of geographical attributes. As shown in FIG. 3, there are types of land use such as housing, forests, agricultural land, and highways. For example, in the case of emergency response in the event of a disaster, it is desirable to prioritize the residential area over the forest area. Therefore, if the priority is set for each land use use, the priority order for each change area can be determined by obtaining the land use use of the change area extracted by using the SAR image. In the disaster response support device 1 of the present embodiment, the priority of the changing area is determined by using the geographical attribute in this way. Hereinafter, a configuration example and operation of the disaster response support device 1 will be described.

Returning to the explanation of FIG. 1, the disaster response support device 1 includes a selection unit 10, a sensor information acquisition unit 11, a geographical attribute acquisition unit 12, an analysis unit 13, a processing information storage unit 14, a priority order determination unit 15, and a priority information storage unit. A unit 16, a planning unit 17, and a condition storage unit 18 are provided. Of these, the selection unit 10, the sensor information acquisition unit 11, the geographical attribute acquisition unit 12, the analysis unit 13, the processing information storage unit 14, the priority order determination unit 15, and the priority information storage unit 16 use the priority generation device 2. Constitute.

The functions of each part of the disaster response support device 1 will be described. The selection unit 10 selects a target area, which is a target area for emergency response. The selection unit 10 selects the target area based on the information input from the operator, for example. The target area may be designated by the operator by the location information which is the information indicating the position, or may be designated by the information indicating the area such as the name of the city, town, or village, and the address. That is, the selection unit 10 may accept the designation of the position information indicating the position of the target area which is the target of the emergency response. It should be noted that the position information may be indicated by the XYZ coordinate values of the 3-axis Cartesian coordinate system with the center of gravity of the earth as the origin even if it is the latitude and longitude, and the format is not particularly limited. Further, the coordinate system of the information indicating the position may be the world geodetic system or the Japanese geodetic system, and the coordinate system is not particularly limited. However, as will be described later, the sensor information and the geographical attribute are also associated with the position information indicating the position. If there is a coordinate value with a different definition among the position information corresponding to the target area, sensor information, and geographical attribute, it is converted to the coordinate value in the coordinate system that is the predetermined reference. Perform processing. There are no particular restrictions on the coordinate system that serves as a predetermined reference.

The sensor information acquisition unit 11 acquires sensor information from the sensor information providing device 3. The sensor information acquisition unit 11 acquires sensor information for each predetermined data size, for example. The defined data size is, for example, the minimum data unit when the sensor information is distributed from the sensor information providing device 3, but is not limited to this. Further, the sensor information acquisition unit 11 may acquire the sensor information for each size of the specified observation area instead of acquiring the sensor information for each specified data size. A set of sensor information determined by the size of the data or the size of the observation area is also hereinafter referred to as sensor information for one image. When the target area is wider than the area corresponding to the sensor information for one image, the sensor information acquisition unit 11 acquires the sensor information for a plurality of images. In this way, the sensor information acquisition unit 11 acquires the sensor information obtained by observing the area including the target area. The sensor information acquisition unit 11 stores the acquired sensor information in the processing information storage unit 14. When the sensor is an artificial satellite, the sensor information providing device 3 calculates the position observed by the sensor based on the orbital position of the artificial satellite, the operating conditions of the sensor, and the like, and the sensor together with the information indicating the position. The observed data or the processed data is processed to provide the data. When the sensor is an artificial satellite, the sensor information acquisition unit 11 acquires sensor information including the target area from the sensor information acquisition unit 11. In the present embodiment, as will be described later, since the change region is calculated by using the difference between the sensor information before and after the occurrence of the disaster, the sensor information acquisition unit 11 at least in the normal time when the disaster does not occur. Once, the sensor information corresponding to the target area is acquired. Alternatively, if the sensor information providing device 3 also provides past sensor information, the sensor information acquisition unit 11 determines the priority of the response after the occurrence of the disaster, and the sensor information after the occurrence of the disaster. At the same time, sensor information in the past, that is, before the occurrence of a disaster may be acquired.

Satellite observation data is generally provided at various levels, from raw data to higher-order products. In the present embodiment, since image data for calculating the change region is required, it is desirable to acquire the image data after calibration and geometric correction peculiar to the sensor have been performed. The image data is, for example, brightness, scattering intensity, altitude, and the like for each pixel. The sensor information acquisition unit 11 may acquire any level of data from the sensor information providing device 3. When low-order level data such as raw data is acquired from the sensor information providing device 3, the analysis unit 13 may perform sensor-specific calibration, geometric correction, or the like to generate image data. Not limited to satellite observation data, sensor-specific calibration and geometric correction are performed on data that is not projected onto a reference plane in a plane.

Similarly, sensor information of sensors mounted on aircraft, vehicles, and the like is also acquired from the sensor information providing device 3 together with position information. However, satellite observation data is acquired regardless of whether or not a disaster has occurred, but sensors mounted on aircraft, vehicles, etc. are in areas where a disaster is expected to occur after a disaster has occurred. May be observed. In this case, the sensor information before the disaster may not be obtained. If the sensor information before the disaster occurs, the sensor information of a similar sensor mounted on the artificial satellite may be used as the sensor information before the disaster occurs. Alternatively, even in normal times, for example, sensors mounted on aircraft, vehicles, etc. may be observed periodically, and the sensor information acquisition unit 11 may acquire sensor information in normal times from the sensor information providing device 3. ..

When the sensor is a sensor with a fixed position, the sensor information providing device 3 may be the sensor itself, a processing device connected to the sensor, or the like. For example, when the sensor is a roadside sensor, a camera installed in a building, or the like, the sensor information acquisition unit 11 may acquire sensor information from a sensor that observes a target area. Alternatively, when the sensor information of a plurality of fixed sensors is aggregated and managed by a server or the like, this server or the like becomes the sensor information providing device 3.

The geographical attribute acquisition unit 12 acquires the geographical attribute information from the geographical attribute providing device 4, and stores the acquired geographical attribute information in the processing information storage unit 14. Geographical attribute information is information in which geographical attributes such as land use, population, and road type are shown for each position. The geographical attribute acquisition unit 12 acquires the geographical attribute information corresponding to the area including the target area. A specific example of the geographical attribute will be described later, but the attribute may be shown for each mesh at equal intervals such as a 100 m mesh, or the attribute is shown for each area such as a municipality or a character. It may be the one.

The analysis unit 13 uses the sensor information to extract a plurality of change regions that are candidates for regions for emergency response. Specifically, the analysis unit 13 extracts the change area in the target area based on the sensor information stored in the processing information storage unit 14, and stores the change area information indicating the change area in the processing information storage unit 14. do. The analysis unit 13 extracts, for example, a change region based on the difference between the sensor information before the occurrence of a disaster and the sensor information after the occurrence of a disaster. For example, the analysis unit 13 extracts a region in which the above difference is equal to or greater than a threshold value as a change region. The change region information includes at least information indicating the position of the change region, and may include a displacement amount, that is, a difference within the change region. Further, the analysis unit 13 aligns the sensor information and the geographical attribute information. When the position information corresponding to the change area information and the position information of the geographical attribute information are indicated by coordinate values having different definitions, the analysis unit 13 arranges the coordinates so that they have the same definition. , Performs coordinate conversion of at least one of the position information corresponding to the change area information and the position information of the geographical attribute information. The analysis unit 13 may determine a reference coordinate system and perform coordinate conversion so that both the position information corresponding to the change area information and the position information of the geographical attribute information become values in the reference coordinate system. , Either one of the position information corresponding to the change area information and the position information of the geographical attribute information may be coordinate-converted to the coordinate values in the other coordinate system. When at least one of the position information corresponding to the change area information and the position information of the geographical attribute information is changed by the coordinate transformation, the analysis unit 13 has changed the information stored in the processing information storage unit 14. Update to information.

Further, when the sensor information acquisition unit 11 acquires a plurality of sensor information corresponding to each of the plurality of sensors, the analysis unit 13 extracts a change region using the plurality of sensor information.

The priority information storage unit 16 holds priority information indicating the correspondence between the value of the geographical attribute and the priority. Specific examples of priority information will be described later. The priority determination unit 15 obtains the geographical attributes corresponding to each of the plurality of change areas using the geographical attribute information, and uses the obtained geographical attributes to obtain the priority of each emergency response of the plurality of change areas. To decide. Specifically, the priority determination unit 15 obtains the geographical attribute corresponding to each change area based on the geographical attribute information and the change area information stored in the processing information storage unit 14, and obtains the geography. The priority of each change area is determined based on the target attribute and the priority information stored in the priority information storage unit 16. The priority order determination unit 15 outputs the determined priority of each change area to the plan creation unit 17.

The condition storage unit 18 stores information such as conditions used by the plan creation unit 17 to create a plan. The condition storage unit 18 stores, for example, conditions related to personnel, supplies, equipment, etc. in the emergency response when the plan creation unit 17 creates a plan for the emergency response. For example, the personnel, supplies, and the like required for one change area that is assumed to be the location where a disaster occurs are stored in the condition storage unit 18. Further, information indicating a list of work to be performed in the emergency response may be stored in the condition storage unit 18. Further, the total amount of supplies held in the target area and the total number of personnel that can be dispatched may be stored in the condition storage unit 18.

The planning unit 17 creates a disaster response plan based on the priority of each change area output from the priority determination unit 15 and the information stored in the condition storage unit 18. For example, first, a plan is created in which the work is performed in chronological order so that the emergency response work is performed on the change area having the priority of 1 and then the emergency response work is performed on the change area having the priority of 2. Alternatively, the work of emergency response in the change area with priority 1 and the work of emergency response in the change area with priority 2 can be started at the same time, and more personnel in the change area with priority 1 than in other change areas. It may be a plan to allocate supplies. If there are a plurality of change areas with a priority of 1 and there is a shortage of personnel for emergency response in the change areas with a priority of 1, a plan may be made such as requesting relief. In addition, a condition may be set such that no emergency response is provided for a change region in which the numerical value of the priority is equal to or higher than the threshold value, that is, a change region in which the priority is lower than a certain level. The method of creating a plan in the plan creating unit 17 is not particularly limited, and may be created according to the type of disaster, the policy predetermined by the local government, etc. using the priority order created by the priority determination unit 15.

The plan created by the planning unit 17 may be a plan for emergency response after a disaster occurs, a plan for disaster countermeasures, or a reconstruction plan. Further, when the disaster response support device 1 detects an abnormal location where a disaster is expected to occur, the plan creation unit 17 creates a plan such as disaster prevention measures for responding to these abnormalities.

The disaster response support device 1 may be installed in a local government such as a prefecture or a municipality, or may be installed in a company or a service center that supports the local government. It may also be installed in a company that is outsourced to respond to disasters. Note that FIG. 1 shows an example in which the disaster response support device 1 includes the plan creation unit 17 and the condition storage unit 18, but the disaster response support device 1 does not include the plan creation unit 17 and the condition storage unit 18. May be good. When the planning unit 17 and the condition storage unit 18 are not provided, the disaster response support device 1 is the same as the priority generation device 2. When the disaster response support device 1 is the same as the priority generation device 2, the disaster response support device 1 is installed in a company or service center that supports the local government, and the disaster response support device 1 is an organization that handles the response such as the local government. Provide priorities to. Local governments, etc. formulate emergency response plans based on the priorities received from the disaster response support device 1.

Here, an operation example of the computer system until the program in which the processing of the disaster response support device 1 is described among the response support programs of the present embodiment becomes executable will be described. In the computer system having the above-described configuration, for example, a first program is installed from a CD-ROM drive or a DVD-ROM set in a CD (Compact Disc) -ROM drive or a DVD (Digital Versatile Disc) -ROM drive (not shown). It is installed in the storage unit 103. Then, when the first program is executed, the first program read from the storage unit 103 is stored in the area serving as the main storage device of the storage unit 103. In this state, the control unit 101 executes the process as the disaster response support device 1 of the present embodiment according to the first program stored in the storage unit 103.

In the above description, a program describing the processing in the disaster response support device 1 is provided using a CD-ROM or a DVD-ROM as a recording medium, but the present invention is not limited to this, and the configuration and provision of a computer system are provided. Depending on the capacity of the program and the like, for example, a program provided by a transmission medium such as the Internet via the communication unit 105 may be used.

The selection unit 10 shown in FIG. 1 is realized by the control unit 101 shown in FIG.

Next, the details of the operation of the present embodiment will be described. FIG. 5 is a flowchart showing an example of disaster response support processing in the disaster response support device 1 of the present embodiment. The disaster response support process shown in FIG. 5 is carried out after an abnormality such as a disaster occurs. As described above, when the sensor information in normal times is acquired in order to extract the change region, the sensor information in the target area is acquired even before the abnormality before the processing shown in FIG. 5 occurs. And store it in the processing information storage unit 14. As shown in FIG. 5, the disaster response support device 1 first selects a target area (step S1). Specifically, the selection unit 10 selects a target area based on an input from an operator or the like or information transmitted from another device. The target area is the area where the disaster response support device 1 is targeted for emergency response. For example, when the disaster response support device 1 is installed in a local government or the like or provides information to the local government or the like, the area corresponding to the local government is selected as the target area.

The disaster response support device 1 acquires sensor information and geographical attributes of the target area (step S2). That is, step S2 includes a sensor information acquisition step for acquiring sensor information and a geographical attribute acquisition step for acquiring geographical attribute information. Specifically, the sensor information acquisition unit 11 acquires sensor information in the target area from the sensor information providing device 3, and stores the sensor information in the processing information storage unit 14. Further, the geographical attribute acquisition unit 12 acquires the geographical attribute information of the target area from the geographical attribute providing device 4, and stores the geographical attribute information in the processing information storage unit 14.

The disaster response support device 1 analyzes the sensor information _{and extracts the change region Ri} (i = 1, 2, ..., N) (step S3). Step S3 is an analysis step in which the disaster response support device 1 uses sensor information to extract a plurality of candidate regions that are candidates for regions for emergency response. n is the number of extracted change regions. In step S3, the analysis unit 13 has, for example, the brightness and scattering of the sensor information observed after the disaster and the sensor information observed before the disaster, which are stored in the processing information storage unit 14, for each pixel. Differences such as intensity and altitude are calculated, and pixels whose difference is equal to or greater than the threshold are extracted. As described above, in the present embodiment, not only disasters but also abnormalities in which a disaster is expected to occur, and abnormalities that are not disasters but somehow may be targeted for response support. In order to extract the area where such anomalies are expected to occur as a change area, the sensor information observed at the time of the anomaly monitoring target is used instead of the sensor information observed after the above disaster. Instead of the sensor information observed before the occurrence of the disaster, the sensor information observed at the time when it is assumed that no abnormality has occurred may be used.

If the difference is equal to or greater than the threshold value in the continuous pixels, the analysis unit 13 sets the portion corresponding to these continuous pixels as one change region. The sensor information includes information on which pixel corresponds to which position. For this information, for example, the position of each pixel and the position of each pixel are calculated based on this position for each image. Consists of information to do. The information on which pixel corresponds to which position is not limited to this format, and may be in any format. The analysis unit 13 can obtain the position of the change region by extracting the pixel whose difference is equal to or larger than the threshold value and then calculating the position corresponding to this pixel based on the above information. The analysis unit 13 stores the position of the change region, that is, the position of the pixel whose difference is equal to or larger than the threshold value, in the processing information storage unit 14 as the change region information. The change region information may include the displacement amount for each change region, that is, the above difference. In general, since the change region includes a plurality of continuous pixels, when the difference differs depending on the pixel, the average value of the plurality of pixels may be used as the displacement amount, or the maximum value may be used as the displacement amount.

Further, the analysis unit 13 uses the information calculated by the survey results, analysis, etc. so far as a reference instead of the sensor information observed before the occurrence of the disaster, which is the reference value for obtaining the change, that is, the difference for each pixel. The difference may be obtained by using it as information. Further, here, an example of comparing the brightness, the scattering intensity, etc. for each pixel is shown, but the present invention is not limited to this, and when the sensor information includes the altitude, the analysis unit 13 may use the sensor acquired in the past. The difference in elevation between the information and the latest sensor information may be obtained, and the portion where the difference is equal to or greater than the threshold value may be obtained as a change region. Further, the analysis unit 13 extracts contours of buildings, rivers, roads, etc. by image processing from both the sensor information acquired in the past and the latest sensor information, and obtains the corresponding contours of the two sensor information. By comparing, the difference between the positions of buildings, rivers, roads, etc. in the direction along the surface of the earth may be obtained, and the region where this difference is equal to or greater than the threshold value may be obtained as the change region.

Further, in the above description, the change region is extracted by comparing with some reference information and obtaining the difference, but the change region may not be extracted by using the reference information. For example, when the sensor information is an infrared image obtained by a sensor that detects infrared light, it is possible to extract a region where the temperature corresponding to the pixel is equal to or higher than the threshold value as a region of change due to fire, volcanic activity, or the like. can. The analysis unit 13 extracts not only an infrared image but also a region of an image obtained as sensor information in which the brightness, scattering intensity, etc. corresponding to the pixels deviate from a predetermined range as a change region. May be good. Alternatively, when the area where the temperature is equal to or higher than the threshold value is equal to or higher than a certain value, the region may be extracted as a change region. Alternatively, a region higher than the average ambient temperature by a certain value or more may be extracted as a change region. As described above, the change region is a region where a change has occurred from the past or a normal state due to some phenomenon, or a region where a difference has occurred from the surroundings. The disaster response support device 1 of the present embodiment treats the change area extracted in this way as a candidate area which is a candidate of the area requiring a response, and determines the priority of the response for each candidate area. The method for calculating the change region is not limited to these examples, and any generally used method may be used. The change region is also referred to as a deformed region.

Next, the disaster response support device 1 performs alignment (step S4). Specifically, when the analysis unit 13 indicates that the change area information and the position information of the geographical attribute are indicated by the coordinate values of different definitions, the analysis unit 13 is represented by the coordinate values of the same definition. Convert at least one of the coordinates. The analysis unit 13 overwrites the coordinate-converted information among the change area information and the position information of the geographical attribute information with the information before the coordinate conversion and stores it in the processing information storage unit 14. The alignment process may be performed by the priority determination unit 15. Further, the coordinate transformation in step S4 may be performed after step S2 and before step S3. In this case, at least one of them is coordinate-transformed so that the position information of the sensor information and the position information of the geographical attribute are represented by the coordinate values of the same definition. Instead of performing the coordinate conversion, the analysis unit 13 adds information for performing the coordinate conversion to at least one of the change area information and the geographical attribute information that require the coordinate conversion, and the processing information storage unit 14 May be stored in. In this case, in the process of determining the priority of the later, the priority order determination unit 15, using the result of coordinate conversion using the information for performing coordinate transformation, obtains a geographic attribute corresponding to the change area R _i ..

Next, the disaster response support device 1 determines the priority of emergency response for each change area based on the geographical attributes corresponding to the change area (step S5). Details of the process of step S5, which is a priority determination step, will be described later. Next, the disaster response support device 1 creates a plan such as emergency response and disaster countermeasures using the priority order for each change area and the information stored in the condition storage unit 18 (step S6). The condition storage unit 18 may store predetermined information in normal times, or may store information input by an operator or the like after an abnormality such as a disaster occurs. The combination may be stored. Further, after step S5, the disaster response support device 1 displays the change area and the corresponding priority on the map on the display unit 104, and the operator or the like confirms this display to create a plan. You may be able to enter the required information. As described above, step S6 may be performed by a device other than the disaster response support device 1. In this case, the disaster response support device 1 outputs the priority order for each change area determined in step S5 and ends the process.

Next, the details of the priority determination process, which is the process of step S5, will be described. FIG. 6 is a flowchart showing an example of the detailed processing procedure of step S5 of the present embodiment. As shown in FIG. 6, the priority order determination unit 15 of the disaster response support device 1 first sets i, which is a variable indicating a change region, to 1 (step S11).

Then, the priority determining unit 15 acquires the geographical attribute corresponding to the change area _{R i} (step S12). In particular, the priority determining unit 15, by using the change area information and geographic attribute information stored in the processing information storage unit 14, obtains the geographic attribute corresponding to the change area R _i. Here, the correspondence between the geographical attribute and the change area will be described using a schematic diagram. FIG. 7 is a schematic diagram showing an example of the change region extracted in step S3 of the present embodiment. Figure 7 is a diagram schematically showing a change region _R 1 to R ₅ which is extracted using a SAR image shown in FIG. 2, the change region _R 1 to R ₅ as shown in FIG. 7 actually SAR It does not correspond to the result calculated using the image. FIG. 8 is a diagram showing the schematic diagram of the change region shown in FIG. 7 and the type of land use use shown in FIG. 3 superimposed. As shown in FIG. 8, the change region R ₁ is farmland and forest, change region R ₂ is forest, the change area R ₃ is highway and forest change region R ₄ is residential and forest, change region _{R 5} is forests. As shown in FIG. 8, if the change area R ₁ to R ₅ and geographical attributes long as it is the alignment, the priority order determination unit 15 determines the respective geographic attributes of the changing area R ₁ to R ₅ be able to.

The geographical attribute information indicating the geographical attribute may be information in which the attribute corresponding to each mesh is indicated in a mesh shape, or information in which the position of an area having the same attribute is indicated. FIG. 9 is a diagram showing an example of land use use shown in a mesh shape, which is an example of geographical attribute information of the present embodiment. In the example shown in FIG. 9, one mesh, that is, one square corresponds to a 100 m square, and the numerical value shown in each mesh indicates the land use use. For example, in the example shown in FIG. 8, 5 indicates a forest, 7 indicates a house, and H indicates a highway. When geographic attributes are shown as such mesh-like information, for example, geographic attribute information includes these matrix-like values and information indicating the location of a reference point on the mesh. .. Therefore, the priority determination unit 15 can determine the position of each mesh based on the geographical attribute information. As described above, depending on the content of the alignment by the analysis unit 13, even if the original mesh is evenly spaced, the mesh may not be evenly spaced in the geographical attribute information acquired by the priority determination unit 15. be.

FIG. 10 is a diagram schematically showing the predicted inundation depth on a map, which is another example of the geographical attribute information of the present embodiment. In FIG. 10, the region 201 shows a region where the predicted inundation depth, which is the predicted inundation depth at the time of flood damage, is _{less than H 1} m, and the region 202 is a region where the predicted inundation depth is H ₁ m or more and _{less than H 2} m. The region 203 shows a region where the predicted inundation depth is H ₂ m or more. FIG. 11 is a diagram showing an example of geographical attribute information of the present embodiment showing the predicted inundation depth. In the example shown in FIG. 11, the coordinates indicating the boundary of the corresponding region are shown for each stage of the predicted inundation depth. FIG. 10 shows on the map each region corresponding to each stage of the predicted inundation depth shown in FIG.

In FIGS. 10 and 11, the predicted value of the inundation depth of flood damage is shown as the predicted value of the damage at the time of the disaster. Not limited to the inundation depth, local governments may prepare predicted values such as the degree of shaking at the time of an earthquake and the degree of damage caused by an earthquake as a hazard map. Predicted values such as the degree of disaster at the time of such a disaster can be used as geographical attribute information.

FIG. 12 is a diagram showing statistical information such as population, which is another example of the geographical attribute information of the present embodiment. As shown in FIG. 12, statistical information such as the population of each region, the number of households, the foreign population, and the elderly population can also be used as geographical attribute information. The item of statistical information shown in FIG. 12 is an example, and the item of statistical information used as geographical attribute information is not limited to the example shown in FIG. For example, a population under the age of 3 may be used as geographical attribute information. These statistical information may be shown in units of cloves as illustrated in FIG. 12, or may be shown in units of areas such as cities, towns and villages. In such a case, the disaster response support device 1 also acquires information indicating the positions of these areas as geographical attribute information. That is, in such a case, the geographical attribute information includes the first information indicating the correspondence between the name of the area and the geographical attribute information, and the second information indicating the position of the area for each name of the area. FIG. 13 is a diagram showing information indicating the position of the area corresponding to the statistical information shown in FIG. The information indicating the position of each area is represented by data in which each area is represented by polygons, data in which boundaries are represented by a plurality of position coordinates, and the like. Priority determining unit 15, for example, determine the name of the corresponding zone to change region R _i by using the second information and the change area information indicating the position of each section illustrated in FIG. 13, by using the first information , The geographical attributes corresponding to the requested area can be obtained.

The geographical attribute of this embodiment may be information regarding the type of road indicating the importance in emergency transportation. The national government, local governments, etc. have established road enlightenment plans in the event of a disaster, emergency transportation roads that are defined as emergency transportation roads, and so on. In addition, the order in which roads are opened may be set in order to control areas that are isolated for a long period of time. Therefore, the disaster response support device 1 can determine the road to which the response should be prioritized by using the information regarding the type of such a road as the geographical attribute information. When the information of the road type is used as the geographical attribute information, the information directly associated with the information indicating the position of the corresponding road may be used as the geographical attribute information for each road type. Alternatively, when the road type is associated with the road name, etc., the geographical attribute information includes the first information indicating the correspondence between the road name and the road type, and the relevant road for each road name. Includes a second piece of information indicating the location of. In the latter case, the priority determining unit 15, similarly to the statistical information, such as the population mentioned above, determine the name of the road corresponding to the change area R _i using the second information, corresponding to the name of the road determined road The attribute of may be obtained based on the first information.

As described above, the geographical attribute information may be information indicating the correspondence between the geographical location and the land use use, or may be information indicating the correspondence between the geographical location and the statistical information regarding the population. In addition, the geographical attribute information may be information indicating the correspondence between the geographical position and the damage level expected before the disaster occurred, and the correspondence between the geographical position and the type of the road indicating the importance in emergency transportation. It may be information indicating. The geographical attribute information is not limited to the above-mentioned example, and may be appropriately selected according to the matters to be considered when the disaster response support device 1 determines the priority.

Returning to the description of FIG. Priority determining unit 15, based on a predetermined priority information to determine the priorities of the changing area R _i (step S13). In particular, the priority determining unit 15, extracts from the priority information stored in the priority information storage unit 16, a geographic attribute obtained in step S12, i.e., the priority of the geographical attribute corresponding to the change area R _i by, prioritizing change region R _i. The priority information is set in advance before the start of the disaster response support process shown in FIG. 5, but may be changed by the operator's input or the like at the start of the disaster response support process. Alternatively, the priority information may be changed by the input of the operator or the like before the process of step S5 after the start of the disaster response support process.

14 to 17 are diagrams showing an example of priority information of the present embodiment. The priority order and the classification of each geographical attribute information shown in FIGS. 14 to 17 are examples of schematically showing the priority information, and the specific contents of the priority order and each geographical attribute information are shown in FIGS. 14 to 17. It is not limited to the example shown in 17.

FIG. 14 shows an example of priority information when the land use use is used as a geographical attribute. In the example shown in FIG. 14, the case where the land use use is a house is set as priority 1, the case where the land use use is a highway is set as priority 2, and the land use use is a forest or a river and the distance from the house. When is less than a certain value, the priority is 3. Further, in the example shown in FIG. 14, the case where the land use use is agricultural land is set as priority 4, and the case where the land use use is forest or river and the distance from the house is a certain value or more is set as priority 5. In the example shown in FIG. 14, not only the land use use but also the distance from the house is used to define the priority. In such a case, the priority determining unit 15, when land-use applications of the changing area R _i forest was river, in step S13, also calculates the distance from the housing to the changed region R _i. For example, the priority order determination unit 15 uses the geographical attribute information and changes the area information, the distance of minimum value of the residential area in the target area and the change area R _i from house to change region R _i Calculated as.

FIG. 15 shows an example of priority information when the predicted damage level is used as a geographical attribute. In FIG. 15, the numerical value of the damage level indicates that the larger the numerical value is, the larger the damage level is. In FIG. 15, examples of countermeasures when the damage level is inundation depth are also illustrated in parentheses. As shown in FIG. 15, for example, the damage level 3 is _{the case where the predicted inundation depth is H 2} m or more, and the damage level 2 is the case where the predicted inundation depth is H ₁ m or more and _{less than H 2} m. 1 is a case where the predicted inundation depth is _{less than H 1 m.} As shown in FIG. 15, the priority is set so that the higher the damage level, the higher the priority.

FIG. 16 shows an example of priority information when statistical information such as population is used as a geographical attribute. In FIG. 16, the ratio of the elderly, that is, the ratio of the elderly population to the population of all age groups, is divided into stages, and the value shown in% is divided into stages, and the priority is set for each stage. In the example shown in FIG. 16, the case where the ratio of elderly people is 70% or more is set as priority 1, the case where the ratio of elderly people is 50% or more and less than 70% is set as priority 2, and the ratio of elderly people is 10. The case of% or more and less than 50% is set as priority 3. The elderly population itself may be used as a geographical attribute instead of the proportion of elderly people.

FIG. 17 shows an example of priority information when the road type is used as a geographical attribute. FIG. 17 shows an example of priority information when the first emergency transport road, the second emergency transport road, and the third emergency transport road are defined. The 1st emergency transport road is the road that should be given the highest priority, the 2nd emergency transport road is the road that should be given the highest priority after the 1st emergency transport road, and the 3rd emergency transport road. Is the road that should be given priority next to the second emergency transportation road. In the example shown in FIG. 17, the primary emergency transport road is prioritized 1, the secondary emergency transport road is prioritized 2, and the tertiary emergency transport road is prioritized 3, and the area has a high risk of isolation. The road leading to is given priority 4.

Further, the position of each road may be used as geographical attribute information. For example, when there are a plurality of change areas corresponding to one road so that the correspondence can be sequentially performed in a certain direction along the road, the change area at either end of these is given high priority and adjacent to each other. The priority may be set so that the corresponding change areas are sequentially dealt with. Further, for example, the priority order determination unit 15 may determine the priority order so that the emergency response proceeds along the way by the methods shown in the following (1) and (2).
(1) First, the priority of a plurality of changing areas is determined based on the geographical attribute information, and then the changing areas along the same road are extracted. If the priority of the changing area along the same road is not determined so that the disaster response will proceed along the road, reset the priority so that the disaster response will proceed along the road.
(2) First, the priority of a plurality of changing areas is determined based on the geographical attribute information. As a result, if the priority of the change area A blocking the road is lower (lower priority) than the priority of the change area B at the end of the road, the change area A in which the disaster response should be performed first. The priority of the change areas A and B is set again so that the priority is higher (higher priority) than the change area B. This is to avoid the contradiction that the change area B has high priority even though the disaster response of the change area B cannot be performed unless the disaster response of the change area A is performed.

Returning to the description of FIG. 6, after step S13, the priority determination unit 15 determines whether or not i = n (step S14). n is the number of change regions extracted in step S3. When i = n (step S14 Yes), the priority determination unit 15 ends the process of step S5. When i = n is not (step S14 No), the priority order determination unit 15 adds 1 to i (step S15) and carries out the processing from step S12.

FIG. 18 is a diagram showing an example of the priority of each change region determined by the process shown in FIG. In the example shown in FIG. 18, using the land use applications as geographic attributes, each of the changing area R ₁ to R ₅ as shown in FIG. 8, in which ranks based on the priority information shown in FIG. 14 .. For example, the change region R ₂ shown in FIG. 8 has a priority of 5 because the land use is for forest and the distance B ₁ from the house is equal to or more than a certain value. It should be noted that the change area _Ri may include a plurality of areas having different geographical attributes. For example, change region R ₁ shown in FIG. 8 includes a region and forest areas of agricultural land. In such a case, the priority determination unit 15 may use the one with the highest priority, that is, the one with the smallest numerical value of the priority among these plurality of geographical attributes, as the priority, or the plurality of these. An average value of a plurality of priorities corresponding to each of the geographical attributes of the above may be used. Further, the priority determination unit 15 weights a plurality of priorities corresponding to each of these plurality of geographical attributes according to the area of the area, and then obtains the average value of the weighted values as the priority. You may. In the example shown in FIG. 18, the change region R _i have used different include a plurality of areas of geographic attributes, the highest-priority ones i.e. the smallest number in the priority, as the priority. Therefore, the area of forest above a certain value is the distance from the housing, the priority of the changing area R ₁ including the area of land is determined in 4 is a priority corresponding to the farmland. Further, the priority of the changing area R ₄ including a residential area, a forest area is determined to 1 is a priority corresponding to the housing.

FIG. 19 is a diagram showing another example of the priority of each change region determined by the process shown in FIG. In the example shown in FIG. 19, using the damage level predicted as geographic attributes, each of the changing area R ₁ to R _5, it is obtained by ranking based on the priority information shown in FIG. 15. Similarly, when other information is used as a geographical attribute, the priority is determined based on the priority information. It is not necessary to prioritize all geographical attributes. For example, when land use is used as a geographical attribute, housing may be prioritized 1, highways may be prioritized 2, and other land use may not be prioritized. In this case, the priority of the response at the time of creating the plan in the change area of the land use use for which the priority is not set is later than the priority of the lowest priority among the land use uses for which the priority is set. It becomes the priority of.

As shown in FIGS. 18 and 19, a plurality of change regions may have the same priority. For example, in the example shown in FIG. 18, the priority of the changing area R ₂ and changing region R ₅ are the same. If the displacement amount of each change area is included in the change area information and a plurality of change areas have the same priority, the priority determination unit 15 may determine these priorities based on the displacement amount. good. Specifically, for example, the priority order determination unit 15 determines the priority order so that the priority is given in descending order of the amount of displacement.

As described above, the disaster response support device 1 of the present embodiment extracts the change area using the sensor information, and when there are a plurality of change areas, the disaster response support device 1 is based on the geographical attributes of each of the plurality of change areas. , Changed to decide the priority of emergency response. Therefore, it is possible to appropriately determine the priority of emergency response. By extracting the change area using the data obtained by multiple sensors aligned and improving the accuracy as sensor information, the change area can be extracted with high accuracy, so it is possible to respond more appropriately in an emergency. Can be prioritized.

Embodiment 2.
Next, the disaster response support process of the second embodiment according to the present invention will be described. The configuration of the disaster response support device 1 of the present embodiment is the same as that of the disaster response support device 1 of the first embodiment. In the present embodiment, the processing in the geographical attribute acquisition unit 12, the priority information stored in the priority information storage unit 16, and the processing in the priority order determination unit 15 are different from those in the first embodiment. Hereinafter, the differences from the first embodiment will be mainly described, and the description overlapping with the first embodiment will be omitted.

In the first embodiment, an example in which one type of information is used as the geographical attribute information has been described. In the present embodiment, the disaster response support device 1 determines the priority using a plurality of types of geographical attribute information. The overall processing of the disaster response support processing of the present embodiment is the same as the processing shown in FIG. 5, except for steps S2 and S5. In step S2 of the present embodiment, the geographical attribute acquisition unit 12 acquires a plurality of geographical attribute information indicating a plurality of types of geographical attributes from the corresponding geographical attribute providing device 4, and acquires the plurality of geographical attributes. The geographical attribute information of the type of is stored in the processing information storage unit 14. For example, the geographical attribute acquisition unit 12 includes geographical attribute information indicating land use, geographical attribute information indicating statistical information such as population, geographical attribute information indicating the predicted damage level, and emergency transportation. The processing information storage unit 14 stores the geographical attribute information indicating the type of the road indicating the importance. Further, in the present embodiment, the content of the priority order determination process, which is the process of step S5, is different from that of the first embodiment.

FIG. 20 is a flowchart showing an example of the processing procedure of the priority order determination process of the present embodiment. Step S11 is the same as that of the first embodiment. After step S11, the priority determining unit 15, for each type of geographic attribute, and acquires the geographical attribute corresponding to the change area R _i (step S21). In particular, the priority determining unit 15 uses a plurality of different geographic attribute information of the type stored in the processing information storage unit 14, for each type of geographic attributes, corresponding to the change area R _i geographic Get the target attribute. For example, the geographical attribute information indicating the land use is used as the attribute information of attribute 1, the geographical attribute information indicating the predicted damage level is used as the attribute information of attribute 2, and the geographical attribute information indicating statistical information such as population is used. The attribute information of the attribute 3 is used, and the geographical attribute information indicating the road type is used as the attribute information of the attribute 4. It is assumed that the processing information storage unit 14 stores the attribute information from the attribute 1 to the attribute 4. Priority determining unit 15, based on the respective attribute information from the attribute 1 to attribute 4, to obtain the four geographical attributes corresponding to the change area R _i.

Then, the priority determining unit 15, with respect to change region R _i, determines an evaluation value of each type of geographic feature based on a predetermined priority information (step S22). FIG. 21 is a diagram showing an example of priority information according to the present embodiment. The priority information of the present embodiment shows the correspondence between the value of the geographical attribute and the evaluation value indicating the priority of emergency response for each type of geographical attribute. Here, it is assumed that the higher the evaluation value, the higher the priority. For example, in the example shown in FIG. 21, for the land use use having attribute 1, the evaluation value of the house is 10, the evaluation value of the main road is 7, and the distance from the house is less than a certain value. Rivers have an evaluation value of 5, agricultural land has an evaluation value of 3, and forests and rivers whose distance from houses is a certain value or more have an evaluation value of 1. The priority information shown in FIG. 21 is an example, and the type of geographical attribute and the evaluation value are not limited to the example shown in FIG.

For example, since change region R ₂ as shown in FIG. 8 is a forest distance from housing leaves a predetermined value or more, the use of priority information as illustrated in FIG. 21, the evaluation value of the attribute 1 of the changing area R ₂ is It becomes 1. Further, when the expected damage level of the changing area R ₂ is assumed to be the damage level 1, the evaluation value of the attribute 2 of the changing area R ₂ is 1. Further, it is assumed that the change area R ₂ is a value that is not defined in the priority information for the attribute 3 and the attribute 4. As described above, when the value is not defined in the priority information, the priority determination unit 15 sets the evaluation value corresponding to the attribute to 0. Change region R _i is, with respect to the geographical attribute of one type, if it contains areas of different geographic attribute, the priority determining unit 15, among the plurality of geographic attributes, high most evaluation value the may be used as the evaluation value of the changing area R _i, may be used such as the average value of the plurality of evaluation values respectively corresponding to the plurality of geographic attributes. For example, change region R ₁ shown in FIG. 8 includes a region and forest areas of agricultural land. In such a case, the priority determining unit 15, an evaluation value 3 farmland, evaluation of 3 change area R ₁ is the value of the larger of the distance is an evaluation value 1 forest above a certain value from the housing may be used as the value may be a 2 is the average value of the evaluation values 1 and evaluation value 3 as the evaluation value of the changing area R _1. Further, the priority determination unit 15 may obtain the evaluation value by weighting these evaluation values according to the area corresponding to each of the plurality of geographical attributes.

Returning to the description of FIG. After step S22, the priority determining unit 15 determines an overall evaluation value of the changing area R _i using the evaluation value of each type of geographic attribute (step S23). The comprehensive evaluation value may be the sum or average value of the evaluation values for each type of geographical attribute, or may be a weighted average value of the evaluation values for each type of geographical attribute. When calculating the weighted average value for each type of geographical attribute, the priority determination unit 15 multiplies the weight of the predetermined type of geographical attribute by the corresponding evaluation value, and the evaluation value after multiplying the weights. The average value of is calculated as the comprehensive evaluation value. The weight of the type of geographic attribute is determined so that the higher the priority of the geographic attribute, the larger the value.

Steps S14 and S15 are the same as those in the first embodiment. If Yes at step S14, the priority determining unit 15 uses the comprehensive evaluation value prioritize changed region _R 1 to R _n (step S24), and ends the priority determining process. FIG. 22 is a diagram showing an example of the priority determined by the priority determination process of the present embodiment. As shown in FIG. 22, the evaluation values of the attributes 1 to 4 are determined in step S22 described above for each change region. In the example shown in FIG. 22, the total evaluation value for each type of geographical attribute is used as the comprehensive evaluation value. In the example shown in FIG. 22, _{the comprehensive evaluation values corresponding to the change regions R 1 to} R ₅ are 4, 2, 16, 24, and 11, respectively. Since the higher the priority of the overall evaluation value, the larger the value, the priority determination unit 15 assigns the priority order from 1 in descending order of the overall evaluation value. That is, the priority determination unit 15 sets the priority of the change region having the maximum comprehensive evaluation value to 1, and assigns the priorities to 2, 3, ... In descending order of the comprehensive evaluation values. In the example shown in FIG. 22, the priority of the change areas R1 to R5 is 4, _{5 , 2, 1, 3, respectively.} When the comprehensive evaluation values of the plurality of change regions are the same, the priority may be the same numerical value, or the priority may be determined based on the displacement amount as in the first embodiment.

As described above, in the present embodiment, the priority determination unit 15 obtains and obtains the geographical attributes corresponding to each of the plurality of change areas by using the geographical attribute information for each type of geographical attribute. The evaluation value is determined using the geographical attribute and the priority information. Then, the priority determination unit 15 determines the priority of each of the plurality of change areas by using the evaluation value for each type of geographical attribute.

In the above-mentioned example, the priority determination unit 15 determines the priority by using the four geographical attribute information indicating the four types of attributes from the attribute 1 to the attribute 4. Two or more of these may be used to determine. Further, the priority determination unit 15 may use geographical attribute information other than the four geographical attribute information described above.

In the above-described example, the evaluation value is set to be larger as the priority is higher, but the evaluation value may be set so that the evaluation value is larger as the priority is lower. In this case as well, the priority order determination unit 15 obtains the comprehensive evaluation value in the same manner as in the above example, and assigns the priority order from 1 in ascending order of the comprehensive evaluation value.
