Embodiments for Carrying Out the Invention

[0014] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings.

[0015] <First Embodiment> The outline of the search support device of the present disclosure will be described.

[0016] FIG. 1 is a diagram schematically showing an example of the configuration of a search support system including a search support device. As shown in FIG. 1, the search support system 1000 includes a search support device 100 and mobile bodies 200-1, 200-2, ···, 200-n (n is a natural number of 1 or more). Here, when not distinguishing each of the mobile bodies 200-1, 200-2, ···, 200-n, the mobile bodies 200-1, 200-2, ···, 200-n are referred to as the mobile body 200. The search support device 100 and the mobile body 200 are communicably connected via a wireless or wired network.

[0017] In the present disclosure, the mobile body is, for example, an unmanned aircraft. The mobile body may be, for example, an airplane, a helicopter, an airship, and a multicopter (also called a multi-rotor helicopter or a multi-rotor, etc.). The unmanned aircraft may also be called a UAV (Unmanned Aerial Vehicle), a small unmanned aircraft, or a drone. In the present disclosure, an example in which the mobile body is an unmanned mobile body will be described, but other examples are not excluded. The mobile body may be, for example, a manned aircraft or a vehicle traveling on the ground.

[0018] The mobile object 200 transmits the transmission information. The transmission information includes location information and identification information of the mobile object 200. The transmission information may further include other information, such as information indicating the time when the mobile object 200 transmitted the transmission information. The mobile object 200 may acquire its own location information using a positioning signal receiving device mounted on the mobile object 200. The positioning signal receiving device receives signals transmitted from positioning satellites of the Global Navigation Satellite System (GNSS), such as Global Positioning System (GPS) satellites, and acquires location information indicating its own location based on the received signals. The location information may include information indicating the altitude of the mobile object. The altitude is acquired, for example, by an altimeter mounted on the mobile object 200. The transmission information may be transmitted, for example, by a remote ID (remote identification) device mounted on the mobile object. The mobile object 200 may transmit the transmission information periodically. For example, the mobile object 200 may transmit the transmission information once per second.

[0019] Furthermore, the mobile object 200 transmits abnormality notification information. The abnormality notification information is information that is transmitted when an abnormality occurs in the mobile object 200, such as the battery running out of charge, a malfunction, or a fall. The abnormality notification information includes identification information of the mobile object 200. The abnormality notification information may further include other information, such as information indicating the time when the mobile object 200 transmitted the mobile object notification information.

[0020] 2 is a block diagram showing an example of the functional configuration of the search support device 100 according to the first embodiment. As shown in FIG. 2, the search support device 100 includes an acquisition unit 110, an identification unit 120, and a calculation unit 130.

[0021] The acquisition unit 110 acquires transmission information and abnormality notification information from the moving body 200. For example, the acquisition unit 110 acquires transmission information from the moving body 200 at any time. At this time, the acquisition unit 110 stores, for example, the identification information and the position information in the storage means in association with each other. And when an abnormality occurs in at least any one of the plurality of moving bodies 200, the acquisition unit 110 acquires abnormality notification information from the moving body 200 in which the abnormality has occurred. In this way, the acquisition unit 110 acquires the abnormality notification information transmitted from the moving body in which the abnormality has occurred among the plurality of moving bodies. The acquisition unit 110 is an example of an acquisition means.

[0022] The specifying unit 120 specifies the attribute of the moving body that has transmitted the abnormality notification information. Here, the moving body that has transmitted the abnormality notification information is also referred to as a search target. The specifying unit 120 specifies the attribute of the search target from the attribute information stored in a storage device (not shown). The storage device is a device that stores various kinds of information. The storage device may be provided in the search support device 100, or may be an external device that can communicate with the search support device 100. The storage device is an example of a storage means. The attribute information is information regarding the attribute of the moving body 200. The attribute information is associated with the identification information of the moving body 200. The attribute includes, for example, the position information of the moving body 200, information regarding the load of the moving body 200, and information indicating whether the owner of the moving body 200 has joined insurance or not. The position information of the moving body 200 may be updated at any time based on the transmission information acquired by the acquisition unit 110, for example. Also, the information regarding the load of the moving body 200 and the information indicating whether the owner of the moving body 200 has joined insurance or not are, for example, information input in advance by the owner of the moving body 200. Note that the attribute is not limited to this example. The attribute may include, for example, information regarding the model such as the size and moving speed of the moving body 200, and information regarding the owner such as the name, address, and contact information of the owner.

[0023] The specifying unit 120 specifies, for example, from the attribute information, the attributes of the search target associated with the identification information of the search target. In this way, the specifying unit 120 specifies the attributes of the search target, which is the moving body that transmitted the abnormality notification information, based on the attribute information regarding the attributes of the moving body stored in the storage means. The specifying unit 120 is an example of a specifying means.

[0024] The calculating unit 130 calculates the search priority for the moving body 200 that transmitted the abnormality notification information. The calculating unit 130 calculates, based on a predetermined rule, the priority corresponding to the attributes specified by the specifying unit 120. The predetermined rule may indicate, for example, the degree of priority determined in advance according to the content of the attribute. For example, when the moving body 200 has fallen in an urban area, the possibility of an accident occurring due to the fall is higher than when it has fallen into a river. Therefore, when the moving body 200 where an abnormality has occurred is located in an urban area (or above an urban area), it is considered that the search should be performed more quickly than when it is located in a river (or above a river). Thus, the predetermined rule includes, for example, a rule of increasing the priority when the latest position information of the search target indicates an urban area compared to when the position information indicates a river. Also, for example, assume that there is a load on the moving body 200. In this case, the predetermined rule may include, for example, a rule of increasing the priority of the search target when the load of the search target is an emergency support material in the event of a disaster or the like. Not limited to this example, the predetermined rule may include rules for calculating the priority according to the content of various attributes. Also, the predetermined rule may be information in which a numerical value is determined for each content of various attributes. The calculating unit 130 may calculate, for example, as the priority, a value obtained by adding numerical values corresponding to the contents of various attributes of the search target. In this way, the calculating unit 130 calculates the search priority corresponding to the attributes of the search target based on a predetermined rule determined in advance. The calculating unit 130 is an example of a calculating means.

[0025] Next, an example of the operation of the search support device 100 will be described with reference to FIG. 3. In the present disclosure, each step of the flowchart is expressed using the number assigned to each step, such as "S1".

[0026] Figure 3 is a flowchart for explaining an example of the operation of the search support device 100. The acquisition unit 110 acquires abnormal notification information transmitted from a mobile body in which an abnormality has occurred among a plurality of mobile bodies (S1). The specifying unit 120 specifies the attribute of the search target, which is the mobile body that transmitted the abnormal notification information, based on the attribute information regarding the attributes of the mobile bodies stored in the storage means (S2). Then, the calculation unit 130 calculates the search priority corresponding to the attribute of the search target based on a predetermined rule (S3).

[0027] As described above, the search support device 100 according to the first embodiment acquires abnormal notification information transmitted from a mobile body in which an abnormality has occurred among a plurality of mobile bodies. Further, the search support device 100 specifies the attribute of the search target, which is the mobile body that transmitted the abnormal notification information, based on the attribute information regarding the attributes of the mobile bodies stored in the storage means. Then, the search support device 100 calculates the search priority corresponding to the attribute of the search target based on a predetermined rule. Thereby, for example, when an abnormality occurs in a plurality of mobile bodies, the search support device 100 can present to the monitor of the mobile body which mobile body should be preferentially searched by providing the search priority. Therefore, the monitor of the mobile body can promptly start searching for the mobile body based on the priority. That is, the search support device 100 according to the first embodiment can support the search for the mobile body.

[0028] <Second Embodiment> Next, a search support system including the search support device according to the second embodiment will be described. In the second embodiment, the search support device 100 described in the first embodiment will be described in more detail. Note that the description of the content overlapping with that described in the first embodiment will be partially omitted.

[0029] FIG. 4 is a diagram schematically illustrating an example of the configuration of the search support system 1000. A mobile object 200 moves through a specific area. A specific area formed in the air for the mobile object 200 to travel through is also referred to as a corridor. The corridor functions as a road for the mobile object 200. The corridor may include a dedicated airspace for the mobile object 200, where services are provided to enable the mobile object 200 to travel safely. Such a dedicated airspace, especially an airspace specialized for drones, is sometimes called a drone highway. In the example of FIG. 4, mobile objects 200-1 and 200-2 are traveling through a corridor formed above a river. An observation device 300 may be placed around the corridor. The observation device 300 is a device capable of communicating with the search support device 100 and the mobile object 200. The observation device 300 and the mobile object 200 communicate with each other using a communication method such as Bluetooth (registered trademark). The communication method is not limited to this example and may be any known method. The observation device 300 receives transmission information and abnormality notification information transmitted from a mobile object 200 passing through a corridor or an area around the corridor. The observation device 300 transmits the transmission information and abnormality notification information to the search support device 100. In this way, the search support device 100 acquires the information transmitted from the mobile object 200. A user of the search support device 100 is, for example, a corridor manager. The user of the search support device 100 begins a search based on, for example, the information provided by the search support device 100.

[0030] 5 is a block diagram showing an example of the functional configuration of a search support system 1000 according to the second embodiment. As shown in FIG. 5, the search support system 1000 includes a search support device 100, a moving object 200, and an observation device 300.

[0031] [Moving Object 200 Details] The mobile body 200 includes a position information acquisition unit 210, an abnormality detection unit 220, and a transmission unit 230. The position information acquisition unit 210 acquires the position information of its own device. The position information acquisition unit 210 has, for example, the function of the positioning signal receiving device described above. The position information acquisition unit 210 periodically acquires the position information. The position information acquisition unit 210 is an example of a position information acquisition means.

[0032] The abnormality detection unit 220 detects an abnormality. For example, the abnormality detection unit 220 detects an abnormality when the remaining battery level becomes less than a predetermined value. Also, the abnormality detection unit 220 may detect that an impact has been applied to its own device as an abnormality. For example, the abnormality detection unit 220 detects an impact caused by dropping or hitting an object such as a building or an animal. Further, the abnormality detection unit 220 may detect that the inside of the mobile body 200 has been flooded as an abnormality. In this case, for example, a mechanism that is energized when wet with water is provided inside the mobile body 200. Therefore, when the mobile body 200 is flooded, the mechanism is energized. The abnormality detection unit 220 may detect the flooding by being energized. The abnormality detection unit 220 is an example of an abnormality detection means.

[0033] The transmission unit 230 transmits transmission information. The transmission information includes the position information acquired by the position information acquisition unit 210 and the identification information of its own device. The transmission unit 230 may periodically transmit the transmission information. Also, when an abnormality is detected by the abnormality detection unit 220, the transmission unit 230 transmits abnormality notification information. Here, when a mechanism that is energized when wet with water is provided inside the mobile body 200, the transmission unit 230 may include a function of transmitting the abnormality notification information when energized due to flooding. The abnormality notification information includes the identification information of its own device. Further, the abnormality notification information may further include information indicating the type of abnormality detected by the abnormality detection unit 220 and the position information when the abnormality is detected. The transmission unit 230 is an example of a transmission means.

[0034] [Details of the Search Support Device 100] The search support device 100 includes an acquisition unit 110, a specification unit 120, and a calculation unit 130. Further, the search support device 100 may further include a setting unit 140. Also, the search support device 100 may have a storage device 190. Note that the storage device 190 is an example of the storage means described above. That is, the storage device 190 may be an external device capable of communicating with the search support device 100.

[0035] The storage device 190 contains mobile body information. The mobile body information is information in which the identification information and the attribute information of the mobile body 200 are associated. FIG. 6 is a diagram showing an example of the mobile body information. In the example of FIG. 6, as the attribute information, items such as "model", "cargo", "scheduled flight time", "scheduled flight route", "position information", "owner name", and "presence or absence of insurance subscription" are set. For example, the record in the first row indicates that the mobile body with the identification information "001" has a model of "α", no cargo, and will fly in the order of location E, location F, location G, and location H from 9:00 to 11:00 on November 15th. Here, the "position information" item indicates at least the position where the mobile body with the identification information "001" is currently flying. The "position information" item may indicate the route of the position flown up to the current time. The "position information" item may be updated, for example, in response to the acquisition of the position information by the acquisition unit 110. Also, the record in the first row indicates that the owner name of the mobile body with the identification information "001" is "X", and the owner is "not subscribed" to the insurance. The insurance may be, for example, a service that preferentially conducts the search for the mobile body. When the mobile body of the owner who has subscribed to the insurance is the search target, for example, in the calculation unit 130, a process of raising the priority is performed.

[0036] The mobile body information is stored in the storage device 190. At this time, the mobile body information is generated, for example, according to a flight plan previously input by the owner. The flight plan is information submitted by the owner before the mobile body 200 performs a flight. The flight plan is, for example, filled in advance by the owner and submitted to the corridor administrator. FIG. 7 is a diagram showing an example of the flight plan. The flight plan includes information such as the location and time at which the mobile body 200 is scheduled to fly, in addition to the identification information of the mobile body 200. In the example of FIG. 7, the flight plan shows the departure point, the scheduled departure time, the arrival point, the scheduled arrival time, the corridor entry point, the corridor exit point, and the flight route. Further, the flight plan may also include information on whether the owner has insurance coverage and information on the cargo carried by the mobile body 200. The mobile body information is generated in advance based on such a flight plan. At this time, the search support device 100 may have a function of receiving the input of the flight plan and a function of generating the mobile body information.

[0037] The acquisition unit 110 includes a transmission information acquisition unit 1101 and an abnormality notification information acquisition unit 1102. The transmission information acquisition unit 1101 acquires the transmission information transmitted by the mobile body 200 via the observation device 300. The transmission information acquisition unit 1101 stores the acquired position information in the storage device 190 in association with the identification information. At this time, the transmission information acquisition unit 1101 may update, for example, the position information item of the mobile body information. The abnormality notification information acquisition unit 1102 acquires the abnormality notification information transmitted by the mobile body 200 via the observation device 300.

[0038] The specific part 120 identifies the attributes of the search target, which is the mobile body that sent the abnormal notification information. For example, when the abnormal notification information acquisition unit 1102 acquires the abnormal notification information, the specific part 120 refers to the identification information included in the abnormal notification information. Then, the specific part 120 identifies the attributes associated with the same identification information as the referred identification information from the mobile body information. For example, assume that the identification information shown in the abnormal notification information is "002". Here, when the mobile body information shown in the example of FIG. 6 is stored in the storage device 190, the specific part 120 identifies the attributes shown in the attribute information of the second row record of the mobile body information. At this time, the specific part 120 may identify only the attributes related to the calculation of the priority. For example, when the calculation unit 130 described later uses the load, location information, and insurance among the attributes for the calculation of the priority, the specific part 120 may identify only the information shown in the items of "load", "location information", and "insurance" in the attribute information.

[0039] The calculation unit 130 includes a rule acquisition unit 1301 and a priority calculation unit 1302. The rule acquisition unit 1301 acquires rule information. The priority calculation unit 1302 calculates the priority of the search target based on the rule information. The rule information indicates a predetermined rule. More specifically, the rule information is information indicating the degree of priority to be given according to the content of the attribute. The rule information is stored in, for example, the storage device 190. The rule information will be described with reference to FIGS. 8A, 8B, and 8C.

[0040] FIG. 8A is a diagram showing a first example of rule information. In the example of FIG. 8A, items of "location information" and "priority" are set in the rule information. That is, the rule information includes a value indicating the priority according to the location indicated by the location information. For example, in the record of the first row, when the location information of the search target indicates a location where there is a railway line, it is shown that the priority is increased by 5. For example, when the search target falls on the railway line, there is a possibility that a train running on the railway line collides with the search target and an accident occurs. Therefore, when the location information of the search target indicates a location where there is a railway line, the priority calculation unit 1302 increases the priority. In this way, the priority calculation unit 1302 calculates the priority according to the location information of the search target. Note that the priority calculation unit 1302 may specify the location indicated by the location information of the search target based on, for example, the location information of the search target and the map information. At this time, the map information may be stored in the storage device 190 or may be acquired through the Internet.

[0041] FIG. 8B is a diagram showing a second example of rule information. In the example of FIG. 8B, items of "cargo" and "priority" are set in the rule information. That is, the rule information includes a value indicating the priority according to the cargo. For example, in the record of the first row, when the cargo of the search target is emergency support supplies, it is shown that the priority is increased by 5. For example, in the event of a disaster, it is assumed that emergency support supplies are delivered to the disaster area or the like by the mobile body 200. The emergency support supplies need to be delivered quickly. Therefore, when the search target has emergency support supplies as the cargo, the priority calculation unit 1302 increases the priority. In this way, the priority calculation unit 1302 calculates the priority according to the information indicating the cargo of the search target.

[0042] FIG. 8C is a diagram showing a third example of rule information. In the example of FIG. 8C, items of "insurance" and "priority" are set in the rule information. That is, the rule information includes information indicating the priority according to whether the owner has joined insurance or not. In this example, it is shown that when the owner has joined insurance, the priority is increased by 3, and when the owner has not joined insurance, the priority is not increased. In this way, the priority calculation unit 1302 calculates the priority according to whether the owner of the search target has joined insurance or not.

[0043] Note that the rule information may include a value indicating the priority according to an attribute other than the above-described attributes. Further, the calculation unit 130 may calculate the priority in consideration of a plurality of attributes. For example, the rule acquisition unit 1301 acquires the rule information of FIGS. 8A to 8C. Here, it is assumed that the moving body with the identification information "002" shown in FIG. 6 is the search target. In this case, since the load of the moving body with the identification information "002" is food with an expiration date of November 18, the priority calculation unit 1302 increases the priority by 2. Further, since the owner of the moving body with the identification information "002" has joined insurance, the priority calculation unit 1302 increases the priority by 3. And if the latest position information of the moving body with the identification information "002" indicates a location in the urban area, the priority calculation unit 1302 increases the priority by 3. That is, the priority calculation unit 1302 calculates the priority of the moving body with the identification information "002" as 8.

[0044] Here, the content of the attribute and the value of the priority corresponding to the content are not limited to the examples in FIGS. 8A to 8C. For example, when the load is a dangerous good, the priority may be higher than when it is an emergency support good. Also, the rule information described with reference to FIGS. 8A to 8C is merely an example. For the sake of simplicity of explanation, an example of calculating the priority of a search target by adding the priority determined according to the attribute has been described, but the rule information is not limited to this example. For example, the rule information may include a rule of increasing the priority regardless of other attributes for the content of a specific attribute. For example, assume that there is one search target whose load is a dangerous good and another search target whose load is not a dangerous good. At this time, the priority calculation unit 1302 may increase the priority of the one search target compared to the other search targets regardless of the content of the attributes of the other search targets.

[0045] The setting unit 140 sets the priority in the search target management information. The search target management information is information indicating the mobile bodies that have become search targets among the plurality of mobile bodies 200. FIG. 9 is a diagram showing an example of the search target management information. In the example of FIG. 9, the items of "identification information", "abnormality flag", and "priority" are set in the search target management information. The abnormality flag is information indicating whether the mobile body is a mobile body in which an abnormality has occurred, that is, whether it has transmitted abnormality notification information. The abnormality flag is updated by the abnormality notification information acquisition unit 1102, for example, when the abnormality notification information acquisition unit 1102 acquires the abnormality notification information. The record in the first row indicates that the mobile body with the identification information "001" has an abnormality flag of "0". This indicates that the mobile body with the identification information "001" has not transmitted the abnormality notification information, that is, it is not a search target. The record in the second row indicates that the mobile body with the identification information "002" has an abnormality flag of "1". This indicates that the mobile body with the identification information "002" has transmitted the abnormality notification information, that is, it is a search target. The setting unit 140 sets, for example, a priority of 8 for the mobile body with the identification information "002". The search target management information is output, for example, to the display of a terminal (not shown) that can communicate with the search support device 100. The user of the search support device 100 can grasp the priority, for example, via the terminal.

[0046] [Operation Example 1 of Search Support System 1000] Next, an example of the operation of the search support system 1000 will be described with reference to FIG. 10. This operation example is an example of the operation when the search support device 100 acquires transmission information. The processing of the observation device 300 is omitted.

[0047] FIG. 10 is a sequence diagram for explaining an example of the operation of the search support system 1000. The position information acquisition unit 210 of the moving body 200 acquires its own position information (S101). The transmission unit 230 transmits transmission information including the position information and the identification information (S102). The transmission information acquisition unit 1101 of the search support device 100 acquires the transmission information via the observation device 300 (S103). Then, based on the acquired transmission information, the transmission information acquisition unit 1101 updates the moving body information (S104). Specifically, the transmission information acquisition unit 1101 identifies the identification information identical to the identification information included in the transmission information from the moving body information. Then, the transmission information acquisition unit 1101 updates the position information associated with the identified identification information so as to indicate the position information included in the transmission information.

[0048] This operation example may be repeated at any time. For example, this operation example may be performed every time the moving body 200 acquires position information.

[0049] [Operation Example 2 of Search Support System 1000] Next, another example of the operation of the search support system 1000 will be described with reference to FIG. 11. This operation example is an example of the operation when the search support device 100 acquires abnormality notification information. The processing of the observation device 300 is omitted.

[0050] FIG. 11 is a sequence diagram for explaining another example of the operation of the search support system 1000. The abnormality detection unit 220 of the moving body 200 detects an abnormality (S201). The transmission unit 230 transmits abnormality notification information (S202).

[0051] The abnormality notification information acquisition unit 1102 acquires the abnormality notification information via the observation device 300 (S203). The identification unit 120 identifies the attributes of the mobile object that transmitted the abnormality notification information (i.e., the search target) (S204). For example, the identification unit 120 identifies the attributes of the search target from the mobile object information based on the identification information included in the abnormality notification information. The rule acquisition unit 1301 acquires rule information from the storage device 190 (S205). The priority calculation unit 1302 calculates the priority of the search target (S206). Specifically, the priority calculation unit 1302 calculates a priority according to the attributes of the identified search target based on the rule information. Then, the setting unit 140 sets a priority according to the search target in the search target management information (S207).

[0052] In this way, the search support device 100 of the second embodiment acquires abnormality notification information transmitted from a mobile object in which an abnormality has occurred among multiple mobile objects. Furthermore, the search support device 100 identifies attributes of the search target, which is the mobile object that transmitted the abnormality notification information, based on attribute information related to the attributes of the mobile objects stored in a storage unit. Then, the search support device 100 calculates a search priority according to the attributes of the search target based on a predetermined rule. As a result, when an abnormality has occurred in multiple mobile objects, the search support device 100 can provide the search priority to a person monitoring the mobile objects (e.g., a corridor manager) to indicate which mobile object should be searched first. Therefore, the person monitoring the mobile objects can quickly start searching for the mobile objects based on the priority. That is, the search support device 100 of the second embodiment can support the search of mobile objects.

[0053] Further, in the second embodiment, the attribute information may include at least any one of the position information when the search target transmitted the abnormality notification information, the information indicating the load of the search target, and the information indicating whether the owner of the search target is insured. Then, the search support device 100 may calculate a priority according to the position information, the information indicating the load of the search target, whether the owner of the search target is insured, and the like. In this way, the search support device 100 can calculate a priority according to various attributes.

[0054] Also, the search support system 1000 of the second embodiment includes a moving body and a search support device. The moving body acquires position information, detects an abnormality, and transmits abnormality notification information when the abnormality is detected. Thereby, the search support system 1000 can identify the moving body in which the abnormality is detected.

[0055] [Modification Example 1] The position information may be acquired by a method that does not use GNSS. For example, the moving body 200 position information acquisition unit 210 may receive a signal transmitted from the observation device 300 installed on the ground and acquire position information indicating its own position based on the received signal.

[0056] For example, as shown in FIG. 4, assume that the moving body 200 is passing through a corridor formed over a river. In this case, the position information acquisition unit 210 of the moving body 200 receives signals from a plurality of observation devices 300 installed on both banks of the river. Then, the position information acquisition unit 210 calculates its own position information using the principle of triangulation.

[0057] <Third Embodiment> Next, the search support system 1001 of the third embodiment will be described. In the third embodiment, an example in which the moving body performs photography will be described. Note that parts of the content overlapping with that described in the first and second embodiments will be omitted from the description.

[0058] FIG. 12 is a block diagram showing an example of the functional configuration of the search support system 1001. As shown in FIG. 11, the search support system 1001 includes a search support device 101, a mobile body 201, and an observation device 300.

[0059] [Details of the mobile body 201] The mobile body 201 is the same as the mobile body 200 described in the first and second embodiments. That is, a plurality of mobile bodies 201 may exist. In addition to the processing of the mobile body 200, the mobile body 201 may perform the following processing.

[0060] The mobile body 201 includes a position information acquisition unit 210, an abnormality detection unit 220, a transmission unit 230, and a photographing unit 240. The photographing unit 240 performs photographing. For example, the photographing unit 240 photographs the periphery of the mobile body 200 while the mobile body 200 is flying. Further, the photographing unit 240 may perform photographing in response to a request from the search support device 101, which will be described later.

[0061] The transmission unit 230 transmits photographing data, which is data corresponding to the image photographed by the photographing unit 240. The photographing data includes identification information. Further, the photographing data may include the time and position information when the photographing unit 240 performs photographing.

[0062] [Details of the search support device 101] In addition to the processing of the search support device 100 described in the first and second embodiments, the search support device 101 may perform the following processing.

[0063] The search support device 101 includes an acquisition unit 111, a specification unit 120, a calculation unit 130, a setting unit 140, and a photographing request unit 150. The search support device 101 also has a storage device 190.

[0064] The imaging request unit 150 requests imaging for one or more moving objects 201. Specifically, the imaging request unit 150 requests the moving object 201 flying around the search target to image the surroundings. For example, the imaging request unit 150 acquires the position information of the search target. Then, based on the position information of the moving object included in the moving object information, the imaging request unit 150 identifies a moving object whose current position is within a predetermined distance from the search target. The moving object identified at this time is a moving object different from the search target. Whether the moving object is the search target is grasped by the abnormality flag in the search target management information. The imaging request unit 150 transmits an imaging request indicating a request for imaging to the identified moving object. The imaging request is transmitted to the identified moving object via the observation device 300.

[0065] The acquisition unit 111 includes a transmission information acquisition unit 1101, an abnormality notification information acquisition unit 1102, and an imaging data acquisition unit 1103. The imaging data acquisition unit 1103 acquires the imaging data transmitted from the moving object 201. At this time, the imaging data acquisition unit 1103 may sequentially acquire the imaging data from the moving object 200. The imaging data acquisition unit 1103 stores the imaging data in the storage device 190.

[0066] The setting unit 141 may associate the imaging data with the search target management information. For example, assume that the moving object 201-1 is the search target. And assume that the moving object 200-2 is flying near the moving object 201-1. In this case, the imaging data acquisition unit 1103 acquires the imaging data from the moving object 200-2. Then, the setting unit 141 associates the imaging data acquired from the moving object 201-2 with the identification information of the moving object 201-1. That is, the setting unit 141 associates the imaging data acquired from the moving object 201 that is not the search target with the identification information of the search target.

[0067] [Operation Example of Search Support System 1001] Next, an operation example of the search support system 1001 will be described with reference to FIG. 13. This operation example is an operation example when the search support device 101 that has acquired the abnormality notification information transmits an imaging request. The processing of the observation device 300 is omitted.

[0068] Since the processes of S301 to S304 are the same as the processes of S201 to S204 in FIG. 11, the description thereof is omitted. The shooting request unit 150 transmits a shooting request to a moving object existing within a predetermined distance from the search target (S305). For example, the shooting request unit 150 calculates the distance between the latest position information of the search target and the latest position information of the moving object included in the moving object information. The shooting request unit 150 transmits a shooting request to a moving object whose distance is within a predetermined value.

[0069] Since the processes of S306 to S308 are the same as the processes of S205 to S207 in FIG. 11, the description thereof is omitted. The shooting data acquisition unit 1103 acquires shooting data (S309). Then, the setting unit 141 stores the acquired shooting data in association with the identification information of the search target (S310).

[0070] As described above, the search support device 101 according to the third embodiment may transmit a shooting request to the search target and a moving object existing within a predetermined distance. Then, the search support device 101 acquires shooting data generated in response to the shooting request from a moving object existing within a predetermined distance. Thereby, the search support device 101 can provide shooting data in which the periphery of the search target is photographed. That is, the search support device 101 can support the search for the moving object.

[0071] [Modification Example 2] In the above embodiment, an example in which the moving object 201 performs shooting in response to the reception of a shooting request has been described. The moving object 201 may perform shooting at all times. For example, the shooting unit 240 performs shooting while the moving object 201 is flying. The transmission unit 230 transmits shooting data at any time. At this time, the shooting data includes position information and shooting time. The shooting data acquisition unit 1103 stores the acquired shooting data in the storage device 190. The setting unit 141 specifies shooting data that is within a predetermined distance from the search target and is shot within a predetermined time from the time when the abnormality notification information is transmitted. Then, the setting unit 141 associates the specified shooting data with the identification information of the search target.

[0072] [Modification Example 3] The search support device 101 may assign value data, which will be described later, to the owner of the moving body that transmitted the imaging data.

[0073] For example, the imaging request unit 150 transmits an imaging request to a moving body 200 different from the search target. Then, the imaging data acquisition unit 1103 acquires imaging data from the moving body 200 to which the imaging request has been transmitted. In this way, the setting unit 141 assigns value data to the owner of the moving body 200 that transmitted the imaging data in response to the imaging request.

[0074] The value data is data indicating an economic value. The value data is, for example, data indicating currency, but is not limited to this example. The value data may be data indicating a value similar to currency that can be exchanged for goods or services. For example, the value data may be points, electronic money, cryptocurrency, and electronic coupons, etc. The setting unit 141 further associates the value data with, for example, owner information associated with the owner's identification information, owner name, and contact information.

[0075] <Fourth Embodiment> Next, the search support system 1002 of the fourth embodiment will be described. In the fourth embodiment, an example of determining the search range will be described. Note that descriptions of content overlapping with that described in the first, second, and third embodiments will be partially omitted.

[0076] FIG. 14 is a block diagram showing an example of the functional configuration of the search support system 1002. As shown in FIG. 14, the search support system 1002 includes a search support device 102, a moving body 201, and an observation device 300.

[0077] [Details of the Search Support Device 102] In addition to the processing of the search support device 100 described in the first and second embodiments, or the processing of the search support device 101 described in the third embodiment, the search support device 102 may perform the following processing.

[0078] The search support device 102 includes an acquisition unit 111, a specification unit 120, a calculation unit 130, a setting unit 140, a shooting request unit 150, a determination unit 160, and a recovery control unit 170. The search support device 102 also has a storage device 190.

[0079] The determination unit 160 determines the search range. The determination unit 160 is an example of determination means. For example, the determination unit 160 sets the range including the position information included in the moving body information as the search range. That is, the determination unit 160 sets the range including the latest position information of the search target as the search range. The determination unit 160 associates the identification information of the moving body 201 with the information indicating the search range and stores the result in the storage device 190.

[0080] The recovery control unit 170 controls a recovery machine (not shown). The recovery machine is a moving body that recovers the search target. The recovery machine recovers the search target automatically or by the operation of the user of the recovery machine, for example, using a capture arm or net that the recovery machine has. The recovery control unit 170 controls at least the movement of the recovery machine to the search range.

[0081] In addition, the recovery control unit 170 controls the recovery machine based on the priority. For example, assume that the moving body 201-1 and the moving body 201-2 are search targets. Also assume that the priority of the moving body 201-1 is 5 and the priority of the moving body 201-2 is 10. In this case, the recovery control unit 170 controls the recovery machine to move to the search range corresponding to the moving body 201-2 with the higher priority. In this way, the recovery control unit 170 controls the recovery machine to move to the search range of the search target with the highest priority among the plurality of search targets.

[0082] [Operation example of the search support system 1002] Next, an operation example of the search support system 1002 will be described with reference to FIG. 15. This operation example is an operation example when the search support device 102 that has acquired the abnormality notification information determines the search range. Also, the processing of the observation device 300 is omitted.

[0083] The processes of S401 to S407 are the same as those of S201 to S207 in FIG. 11, so the description is omitted. The determination unit 408 determines the search range of the search target (S408). The recovery mechanism control unit 170 controls the recovery machine (S409). For example, the recovery mechanism control unit 170 moves the recovery machine to the search range of the search target with a higher priority among the plurality of search targets.

[0084] Note that in this operation example, the processes related to the transmission of the shooting request and the acquisition of the shooting data described in FIG. 13 are omitted. However, the processes related to the transmission of the shooting request and the acquisition of the shooting data described in FIG. 13 may be performed in this operation example.

[0085] In this way, the search support device 102 of the fourth embodiment determines the latest position information of the search target as the search range of the search target. Then, the search support device 102 moves the recovery machine to the search range corresponding to the search target with a higher priority among the plurality of search targets. Thereby, the search support device 102 can search for the search targets in descending order of priority among the plurality of search targets.

[0086] [Modification Example 4] When an abnormality occurs and the mobile body falls, there is a possibility that the transmission information cannot be transmitted. That is, there may be a case where the position information of the search target is not updated after the search target transmits the abnormality notification information. In this case, the determination unit 160 may estimate the search range.

[0087] For example, the determination unit 160 identifies the position information when the search target transmitted the abnormality notification information from the moving body information. Then, the determination unit 160 acquires information regarding the terrain corresponding to the identified position information. The information regarding the terrain is map information including altitude and slope information. For example, if the search target falls in a sloped place such as a mountainside or a slope, the search target may roll along the slope. Also, for example, if the search target falls into a river, the search target may be washed away by the river. Thus, the search target may move due to the terrain of the place where it fell. The determination unit 160 estimates the range within which the search target moves due to the terrain from the identified position information based on the information regarding the terrain. Then, the determination unit 160 determines the range within which the search target moves due to the terrain as the search range.

[0088] In this way, the search support device 102 may determine the search range of the search target based on the position information when the search target transmitted the abnormality notification information and the information regarding the terrain corresponding to the position information. Thereby, even when the search target does not transmit the transmission information including the position information after transmitting the abnormality notification information, the search support device 102 can provide the search range.

[0089] <Fifth Embodiment> Next, the search support system 1003 of the fifth embodiment will be described. In the fifth embodiment, the processing of the moving body when an abnormality is detected will be described. Note that the description of the content overlapping with that described in the first, second, third, and fourth embodiments will be partially omitted.

[0090] FIG. 16 is a block diagram showing an example of the functional configuration of the search support system 1003. As shown in FIG. 16, the search support system 1003 includes a search support device 102, a moving body 202, and an observation device 300. Note that the search support system 1003 may include the search support device 100 or the search support device 101 instead of the search support device 102.

[0091] [Details of the Moving Body 202] In addition to the processing of the search support device 100 described in the first and second embodiments, or the processing of the search support device 101 described in the third embodiment, the mobile body 202 may perform the following processing.

[0092] The mobile body 202 includes a position information acquisition unit 210, an abnormality detection unit 220, a transmission unit 230, a photographing unit 241, and a control unit 250.

[0093] The photographing unit 241 may perform photographing when an abnormality is detected. For example, the photographing unit 241 starts photographing when an abnormality is detected by the abnormality detection unit 220.

[0094] The control unit 250 controls the own vehicle based on the photographed data. Specifically, the control unit 250 reads control information from the image photographed by the photographing unit 241. Here, the control information is information that can be read by the mobile body 202 and is information for controlling the mobile body 202. FIG. 17 is a diagram showing an example of a situation where the mobile body 202 reads control information. In the example of FIG. 17, the control information is attached to the observation device 300. Here, it is assumed that an abnormality is detected in the mobile body 202. In this case, the photographing unit 241 of the mobile body 202 starts photographing. The surroundings of the mobile body 202 are reflected in the photographed image. When the control information is reflected in the photographed image, the control unit 250 reads the control information. Then, the control unit 250 controls the own vehicle based on the read control information. For example, the control unit 250 approaches the location where the read control information is attached and lands.

[0095] The control information may be a two-dimensional code or a one-dimensional code in which various types of information are recorded. In this case, the control information may include information indicating a location. The control unit 250 may control the own aircraft to land at the location included in the control information by reading the control information. Also, not limited to this example, the control information may be symbols, marks, etc. In this case, the control unit 250 may approach the read control information and land the own aircraft. Also, the control information does not have to be attached to the observation device 300. For example, the control information may be attached or drawn at a location where landing is possible. For example, when the control information exists on the ground, the control unit 250 may control the own aircraft to land on the read control information.

[0096] In this way, the control unit 250 reads the control information included in the image captured by the imaging unit 241 and lands the own aircraft based on the control information. The control unit 250 is an example of a control means.

[0097] [Operation Example of Search Support System 1003] Next, an operation example of the search support system 1003 will be described with reference to FIG. 18. This operation example is an operation example of the moving body 202 in which an abnormality is detected.

[0098] FIG. 18 is a flowchart for explaining an example of the operation of the moving body. The abnormality detection unit 220 detects an abnormality (S601). Then, the transmission unit 230 transmits abnormality notification information (S602). The imaging unit 241 captures the surroundings (S603). The control unit 250 reads the control information from the captured image (S604). The control unit 250 controls the own aircraft according to the read control information (S605). For example, the control unit 250 approaches the read control information and lands the own aircraft.

[0099] As described above, when an abnormality is detected, the search support system 1003 of the fifth embodiment starts imaging, reads control information included in the image captured by the imaging means, and lands the own vehicle based on the control information. As a result, the search support system 1003 can land a moving body in which an abnormality has occurred at a specific location. Therefore, the search support system 1003 can facilitate the search for the moving body in which an abnormality has occurred.

[0100] <Example of the hardware configuration of the search support system> The hardware constituting the search support device or the moving body according to the first, second, third, fourth, and fifth embodiments described above will be described.

Note that the search support device and the moving body may be realized by a plurality of electric circuits.

[0102] The storage device 94 stores a program (computer program) 98. The processor 91 executes the program 98 of the present search support device using the RAM 92. Specifically, for example, the program 98 includes a program that causes a computer to execute the processes shown in FIGS. 3, 10, 11, 13, 15, and 18. When the processor 91 executes the program 98, the functions of the respective components of the present search support device and the present moving body are realized. The program 98 may be stored in the ROM 93. Further, the program 98 may be recorded on a storage medium 80 and read using the drive device 97, or may be transmitted from an external device (not shown) to the computer device 90 via a network (not shown).

[0103] The input / output interface 95 exchanges data with peripheral devices (such as keyboards, mice, display devices, etc.) 99. The input / output interface 95 functions as a means for acquiring or outputting data. The bus 96 connects each component.

[0104] Note that there are various modifications to the search support device and the method for realizing the mobile body. For example, the search support device can be realized as a dedicated device. Also, the search support device can be realized based on a combination of multiple devices.

[0105] A processing method that records a program for realizing each component in the functions of each embodiment on a storage medium, reads the program recorded on the storage medium as code, and executes it on a computer is also included in the scope of each embodiment. That is, a computer-readable storage medium is also included in the scope of each embodiment. Also, the storage medium on which the above program is recorded, and the program itself are also included in each embodiment.

[0106] The storage medium is, for example, a floppy (registered trademark) disk, hard disk, optical disk, magneto-optical disk, CD (Compact Disc)-ROM, magnetic tape, non-volatile memory card, or ROM, but is not limited to this example. Also, the program recorded on the storage medium is not limited to a program that executes processing alone, and programs that operate on an OS (Operating System) and execute processing in cooperation with the functions of other software and expansion boards are also included in the scope of each embodiment.
