[0003] [Patent Document 1] JP 2017-117005 A Summary of the Invention [Problem to be solved by the invention]

[0004] The above-mentioned technology is based on the premise that a vehicle equipped with a drive recorder having a function for detecting the occurrence of an accident is present near the scene of the accident. However, when some event such as an accident (hereinafter referred to as "event" in this specification) occurs, a vehicle having a function for detecting the event is not always present at the scene.

[0005] The present invention has been made in consideration of these points, and has an object to provide a technique for promoting the provision of information about events such as accidents. [Means for solving the problem]

[0012] A third aspect of the present invention is a program that causes a computer to perform the following functions: acquiring event location information indicating a location where an event occurred, acquiring event date and time information indicating the date and time when the event occurred, referring to a recorder database that associates and stores a recording device identifier for identifying an information recording device that is mounted on a vehicle and records external information indicating information outside the vehicle, date and time information acquired from the information recording device, and vehicle location information indicating the location of the vehicle at the date and time, and identifying a recording device identifier of an information recording device mounted on a vehicle that was present within a predetermined range including the event location information during a predetermined time period including the date and time indicated by the event date and time information, and notifying a contact associated with the recording device identifier of a message requesting the provision of external information captured during a predetermined time period including the date and time indicated by the event date and time information.

[0013] In order to provide this program or to update a part of the program, a computer-readable recording medium having this program recorded thereon may be provided, or this program may be transmitted over a communication line.

[Figure 7] 4 is a flowchart illustrating a flow of information processing executed by an information processing device according to an embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] <Outline of the embodiment> An overview of an information processing device according to an embodiment of the present invention will be described. The information processing device according to the embodiment is, for example, a server under the management of a company that includes automobile insurance as one of its products. The information processing device according to the embodiment periodically collects location information indicating the location of each of a plurality of vehicles together with time information, and identifies a vehicle that was traveling near a location around the date and time when some event, such as a hit-and-run, a hit-and-run accident, a property damage accident, a home invasion, or a fire, occurred. Thereafter, the information processing device 1 requests the user of the identified vehicle to provide information generated by an information recording device, such as a drive recorder, mounted on the vehicle. In this way, the information processing device 1 according to the embodiment can promote the provision of information about events such as accidents.

[0018] 1 is a diagram for explaining an overview of the flow of information processing executed by an information processing device 1 according to an embodiment. The flow of information processing executed by the information processing device 1 will be explained below in the order of (1) to (5), and the numbers correspond to (1) to (5) in FIG. 1.

[0019] (1) The information processing device 1 periodically collects information from an information recording device installed in a vehicle C of a user who has given consent in advance to the provision of information. The information recording device is a device known as a drive recorder, dashcam, or the like, and records information such as video and audio outside the vehicle in which it is installed in association with date and time. The information generated by the information recording device may be video generated by a normal imaging element for capturing images in the visible light region, video in the infrared region generated by an infrared camera for capturing images in the infrared region, or point cloud data acquired by a three-dimensional laser scanner. The information recording device may also include information not only about the front of the vehicle C in which it is installed, but also about the rear and sides.

[0020] The information that the information processing device 1 according to the embodiment periodically collects from the information recording device mounted on the vehicle C is location information indicating the location where each vehicle C was present, and date and time information indicating the date and time when the vehicle C was present at that location. The location information is information acquired by the information recording device using a satellite positioning system (Global Navigation Satellite System; GNSS). Since the date and time information and the date information are at most several tens of bytes of information, even if the information processing device 1 collects information every minute from one million vehicles, the amount of information collected in one day (24 hours) is on the order of 10 gigabytes.

[0021] 1 shows four vehicles C, from a first vehicle C1 to a fourth vehicle C4, communicating with an information processing device 1. Specifically, each vehicle C transmits information to the information processing device 1 via a base station B and a communication network N that constitute a mobile phone communication network. For this reason, the vehicle C is equipped with a known mobile phone communication module (not shown). Each device equipped in the vehicle C, including the information recording device, can communicate with devices outside the vehicle C via the mobile phone communication module.

[0022] (2) The information processing device 1 stores the information acquired from each vehicle C in the recorder database 100 in association with a recording device identifier for identifying the information recording device installed in each vehicle C. Although only four vehicles C, from the first vehicle C1 to the fourth vehicle C4, are illustrated in FIG. 1, the number of vehicles C with which the information processing device 1 communicates is more than four, for example, on the order of one million, and distributed over a wide area (for example, all over Japan). In this way, the information processing device 1 collects information indicating when and where the vehicle C of a user who has given consent was located from the information recording device, and accumulates the information in the recorder database 100.

[0023] (3) The information processing device 1 acquires event location information indicating the location where some event I (e.g., a hit-and-run accident) for which eyewitness information is desired occurred, and event date and time information indicating the date and time when the event I occurred. The information processing device 1 acquires the event location information and the event date and time information based on an information collection request, for example, from an accident victim or a public institution such as the police investigating the accident. In the example shown in Fig. 1, a collision accident that occurred near a pedestrian crossing at an intersection is illustrated as event I.

[0024] (4) The information processing device 1 refers to the recorder database 100 to identify a specific vehicle, which is vehicle C that was present within a predetermined range including the position identified by the event position information within a predetermined time period before and after the date and time identified by the event date and time information. More specifically, the information processing device 1 identifies the recording device identifier of the information recording device mounted on the specific vehicle.

[0025] In the recorder database 100, contact information for contacting a user is registered, linked to the recording device identifier of the information recording device mounted in the vehicle C of a user for whom consent has been obtained in advance. The contact information may be, for example, the user's email address, telephone number, or address, or may be a series of information including an API (Application Programming Interface) for displaying a message on the display unit of the information recording device and an API for outputting sound on the sound output unit of the information recording device, or may be a series of information including an API for displaying a message on a car navigation system mounted in the user's vehicle C and an API for outputting sound on the sound output unit of the car navigation system.

[0026] (5) The information processing device 1 notifies the contact point corresponding to the recording device identifier of the information recording device mounted on the specific vehicle of a message requesting the provision of information recorded by the information recording device. This allows the information processing device 1 to call for the provision of information from users of information recording devices that are likely to have recorded information related to event I. This allows the information processing device 1 to efficiently call for the provision of information from people who are likely to have information related to event I, such as an accident, and therefore promotes the provision of information.

[0027] <Functional configuration of information processing device 1 according to the embodiment> FIG. 2 is a diagram showing a schematic functional configuration of an information processing device 1 according to an embodiment. The information processing device 1 includes a storage unit 10, a communication unit 11, and a control unit 12. In FIG. 2, arrows indicate main data flows, and there may be data flows not shown in FIG. 2. In FIG. 2, each functional block indicates a functional unit configuration, not a hardware (device) unit configuration. Therefore, the functional blocks shown in FIG. 2 may be implemented in a single device, or may be implemented separately in multiple devices. Data may be exchanged between functional blocks via any means, such as a data bus, a network, or a portable storage medium.

[0028] The storage unit 10 is a large-capacity storage device such as a ROM (Read Only Memory) that stores the BIOS (Basic Input Output System) of the computer that realizes the information processing device 1, a RAM (Random Access Memory) that serves as the working area of ​​the information processing device 1, an HDD (Hard Disk Drive) or an SSD (Solid State Drive) that stores the OS (Operating System), application programs, and various information referenced when the application programs are executed.

[0029] The communication unit 11 is a communication interface for the information processing device 1 to communicate with external devices, such as a user terminal owned by a user whose consent has been obtained in advance, an information recording device, a car navigation system, a recorder database 100, etc., and is realized by a known communication module such as a LAN (Local Area Network) module or a Wi-Fi (registered trademark) module. Hereinafter, in this specification, the description of the communication unit 11 may be omitted on the assumption that communication between the information processing device 1 and external devices is performed via the communication unit 11.

[0030] The control unit 12 is a processor such as a CPU (Central Processing Unit) or GPU (Graphics Processing Unit) of the information processing device 1, and functions as an event information acquisition unit 120, an identification unit 121, a notification unit 122, a database management unit 123, a consent acquisition unit 124, an information acquisition unit 125, and an extraction unit 126 by executing programs stored in the memory unit 10.

[0031] 2 shows an example in which the information processing device 1 is configured as a single device. However, the information processing device 1 may be realized by a plurality of processors, memories, and other computing resources, such as a cloud computing system. In this case, each unit constituting the control unit 12 is realized by at least one of a plurality of different processors executing a program.

[0032] The event information acquisition unit 120 acquires event location information indicating the location where the event I occurred, and event date and time information indicating the date and time when the event occurred. The event location information is specified by, for example, a combination of latitude and longitude. The event date and time information is specified by a year, month, day, and time. The event information acquisition unit 120 acquires the event location information and the event date and time information via the communication network N, for example, from the terminals of the victims and related parties who are requesting information about the accident.

[0033] The recorder database 100 stores, in association with one another, a recording device identifier for identifying the information recording device installed in vehicle C, date and time information obtained from the information recording device, and vehicle position information indicating the position of vehicle C at the date and time identified by the date and time information.

[0034] FIG. 3 is a diagram showing an example of the data structure of the recorder database 100 according to the embodiment. In the example of the recorder database 100 shown in FIG. 3, it is shown that the information recording device having the recording device identifier DID0000001 was present at 36 degrees 12 minutes 45.28 seconds north latitude and 140 degrees 6 minutes 0.8 seconds east longitude at 12:34:56 on January 23, 2023. In addition, in the example of the recorder database 100 shown in FIG. 3, the user's contact information and the vehicle registration number plate (so-called "number plate") of the user's vehicle C are also recorded in association with the recording device identifier. For example, in FIG. 3, the contact information of the user of the vehicle C equipped with the information recording device having the recording device identifier DID0000001 is an email address, specifically "abc@def.com". In addition, the vehicle registration number plate is Shinagawa 330 XX-XX.

[0035] Returning to the explanation of FIG. 2, the identification unit 121 refers to the recorder database 100 and identifies the recording device identifiers of the information recording devices mounted on vehicles that were present in a predetermined range including the event location information during a predetermined time period including the date and time indicated by the event date and time information acquired by the event information acquisition unit 120. Here, the "predetermined time period" is a time range for identifier identification that the identification unit 121 refers to in order to identify the recording device identifier. The larger the time range is, the more recording device identifiers the identification unit 121 will identify, but the number of information recording devices that do not hold information related to the event I may also increase. For this reason, the specific size of the predetermined time period may be determined taking into consideration the nature of the event I that is the subject of the information provision, and an example is 5 minutes before and after the date and time indicated by the event date and time information.

[0036] The "predetermined range" is a spatial range for identifying an identifier that the identifying unit 121 refers to in order to identify a recording device identifier. As with the time range, the larger the spatial range, the more recording device identifiers the identifying unit 121 will identify, but the number of information recording devices that do not hold information related to the event I may also increase. Therefore, the specific size of the predetermined time period may be determined taking into consideration the nature of the event I for which information is provided, and as an example, it may be a circular range with a radius of 3 kilometers centered on the position indicated by the event position information. In addition, if the event I is a contact accident on a specific road, the predetermined range may be a circular range with a radius of 10 kilometers from the position indicated by the event position information, provided that the information is installed in the vehicle C that was traveling on the road on which the accident occurred during the predetermined time period.

[0037] The notification unit 122 notifies the contact associated with the recording device identifier of a message requesting the provision of outside information captured during a predetermined time period including the date and time indicated by the event date and time information. This enables the information processing device 1 to promote the provision of information about the event I such as an accident.

[0038] 3, the recorder database 100 records date and time information and vehicle position information in association with each of the multiple recording device identifiers. To achieve this, the information processing device 1 is equipped with a database management unit 123. The database management unit 123 acquires date and time information and vehicle position information from each of the multiple information recording devices via the communication network N, and stores the information in the recorder database 100 in association with each recording device identifier. This allows the information processing device 1 to collectively manage the locations of the multiple vehicles C together with the locations.

[0039] 4 is a diagram illustrating an internal configuration of the identification unit 121 according to the embodiment. As illustrated in FIG. 4, the identification unit 121 includes a trajectory identification unit 1210 and an identifier identification unit 1211.

[0040] The trajectory identification unit 1210 identifies the trajectory of the position information associated with each recording device identifier by referring to the recorder database 100. The identifier identification unit 1211 identifies, from the trajectories identified by the trajectory identification unit 1210, the recording device identifiers of the information recording devices mounted on vehicles that were present in a predetermined range including the event position information during a predetermined time period including the date and time indicated by the event date and time information.

[0041] Fig. 5 is a diagram showing a schematic diagram of the location of a vehicle C equipped with a recording device identifier identified by the identifier identification unit 1211 according to the embodiment, and shows the location of the vehicle C superimposed on a map showing roads. Although not all of the diagrams are shown to avoid complication, the white arrows marked with the symbols C (Ca and Cb) in Fig. 5 represent the vehicle C equipped with the recording device identifier identified by the identifier identification unit 1211, and the direction of the arrow indicates the traveling direction of the vehicle. The white star marked with the symbol I indicates the location where the event I occurred. Fig. 5 shows the location of the vehicle C at the date and time when the event I occurred.

[0042] In Fig. 5, circle A marked with a symbol A indicates a part of the above-mentioned predetermined range, specifically, the boundary line of a range with a radius of 3 kilometers centered on the occurrence position of event I. In the example shown in Fig. 5, event I is an accident that occurred near a pedestrian crossing on a public road. If the average speed of vehicle C on the public road is assumed to be 36 kilometers per hour (10 meters per second), and the predetermined time period is 5 minutes (300 seconds) before and after the date and time indicated by the event date and time information, the identifier identifying unit 1211 will identify the recording device identifier of the information recording device mounted on vehicle C that was present within a range of 3 kilometers (10 meters per second x 300 seconds = 3000 meters) centered on the occurrence position of event I on the date and time of event I.

[0043] 5 shows that the number of vehicles C identified inside the circle A was six. More specifically, the number of vehicles C of users who have given prior consent to the provision of information inside the circle A was six, and the possibility that there were more than six vehicles C inside the circle A cannot be denied.

[0044] Among the six vehicles identified by the identifier identification unit 1211, vehicle Ca, which is marked with a symbol Ca, is traveling in the direction of event I near the location where event I occurred at the date and time of event I. Therefore, there is a high probability that the information recording device mounted on vehicle Ca has recorded information about event I (for example, a video image showing event I).

[0045] Here, in FIG. 5, the vehicle Cb indicated by the symbol Cb is located at a position more than 3 kilometers away from the occurrence position of the event I and is moving in a direction away from the event I. For this reason, it is unlikely that the information recording device mounted on the vehicle Cb itself records information about the event I. However, since the vehicle Cb is traveling on the same road as the road on which the event I occurred, it is possible that the vehicle Cb is equipped with an information recording device that is not registered in the recorder database 100 and holds information about another vehicle C that was traveling in the oncoming lane toward the direction in which the event I occurred. For example, if the information recording device mounted on the vehicle Cb records a video showing the self-propelled vehicle registration plate of the other vehicle, a person who wants information about the event I can request the user of the other vehicle C to provide the information.

[0046] In this way, the identifier specifying unit 1211 specifies, from among the recording device identifiers of information recording devices registered in the recorder database 100, the recording device identifier of an information recording device mounted on a vehicle C that was present within a predetermined range from the location where event I occurred during a predetermined time period including the date and time of event I, and the recording device identifier of an information recording device mounted on a vehicle C that was traveling on the road on which event I occurred during a predetermined time period including the date and time of event I. This enables the notification unit 122 to efficiently request the provision of information from the user of the vehicle C mounted with an information recording device that is highly likely to have recorded information about event I.

[0047] The information recorded by the information recording device mounted on each vehicle C is information indicating when and where the user of the vehicle C was, and is private information. Therefore, even if there is a high probability that information related to the event I is recorded, there may be cases where the information processing device 1 should not obtain the information recorded by the information recording device without the user's consent.

[0048] Therefore, in order to obtain consent from the user, the consent acquisition unit 124 displays a message prompting consent on, for example, the display unit of a mobile terminal or information recording device owned by the user. Fig. 6 is a diagram showing an example of a message presented to the user by the consent acquisition unit 124. Specifically, Fig. 6 shows an example of a case where the consent acquisition unit 124 displays a message on the display unit of a car navigation system installed in a vehicle C. In this example, if the user who has checked the message consents to the provision of information, he or she can consent by accessing a website (not shown) from a web link in an email received on his or her mobile phone and checking a predetermined checkbox.

[0049] The consent acquisition unit 124 acquires consent for the provision of external information from the method associated with the recording device identifier identified by the identification unit 121. The "method associated with the recording device identifier" may be, for example, a method of checking a checkbox on a website, or, for example, a method of the user mailing a signature indicating consent. Alternatively, consent may be obtained in advance from the user when purchasing a product such as insurance. The information acquisition unit 125 receives external information for a predetermined time period including the date and time of occurrence of event I from the information recording device corresponding to the recording device identifier, on condition that the consent acquisition unit 124 acquires consent. This makes it possible for the information processing device 1 to suppress acquisition of external information such as video without the user's consent.

[0050] Note that the information acquisition unit 125 may acquire the external information from the information recording device via a route other than the route for receiving the external information from the information recording device via a communication line. For example, if the information recording device is equipped with a memory card for storing the external information, the information acquisition unit 125 may read the external information directly from the memory card. In this case, the notification unit 122 notifies the contact associated with the recording device identifier identified by the identification unit 121 of a message requesting the provision of the memory card together with the delivery destination information. This allows the information acquisition unit 125 to acquire the external information by reading it from the memory card that has been mailed.

[0051] When the information recording device is a so-called drive recorder and the external information acquired by the information acquisition unit 125 is an image capturing the outside of the vehicle C, the image may include an image of the vehicle registration plate of the vehicle C (including the vehicle C traveling in the oncoming lane) traveling ahead of the vehicle C in the traveling direction. When the information recording device has a function of capturing an image of the rear of the vehicle C, the external information acquired by the information acquisition unit 125 may include an image of the vehicle registration plate of the vehicle C traveling behind the vehicle C in the traveling direction.

[0052] Therefore, the extraction unit 126 analyzes the video acquired by the information acquisition unit 125 and extracts the vehicle registration plate of the vehicle C shown in the video. The extraction unit 126 can realize the function of extracting the vehicle registration plate by using a character recognition module generated by a known machine learning method such as a deep neural network.

[0053] When the vehicle registration plate extracted by the extraction unit 126 is stored in the recorder database 100, the database management unit 123 can identify the contact information of the user of the vehicle C by using the vehicle registration plate as a key. Even if consent to the provision of information has not been obtained from the user, depending on the severity of the event I, the administrator of the information processing device 1 can request the user to provide information again.

[0054] Furthermore, if the vehicle registration plate extracted by the extraction unit 126 is not stored in the recorder database 100, that is, if the user of the vehicle C to which the vehicle registration plate extracted by the extraction unit 126 is attached is not a customer of the administrator of the information processing device 1, it is generally difficult for the administrator of the information processing device 1 to obtain the contact information of the user. However, for example, if the requester of the information provision is a specific public institution, it may have a means of identifying the owner of the vehicle C from the vehicle registration plate. In such a case, the vehicle registration plate extracted by the extraction unit 126 becomes a clue for providing information.

[0055] In this way, the extraction unit 126 extracts the vehicle registration plate from the video, and the information processing device 1 can obtain a clue to provide information in addition to the recording device identifier identified by the identification unit 121. As a result, the information processing device 1 can promote the provision of information about events such as accidents.

[0056] <Processing flow of the information processing method executed by the information processing device 1> 7 is a flowchart for explaining the flow of information processing executed by the information processing device 1 according to the embodiment. The processing in this flowchart starts, for example, when the information processing device 1 is started.

[0057] The event information acquisition unit 120 acquires event position information indicating the position where the event I occurred (S2). The event information acquisition unit 120 also acquires event date and time information indicating the date and time when the event I occurred (S4).

[0058] The identifying unit 121 refers to the recorder database 100 and identifies the recording device identifier of the information recording device mounted on the vehicle that was in a predetermined range including the event position information during a predetermined time period including the date and time indicated by the event date and time information (S6). The notifying unit 122 notifies the contact associated with the recording device identifier of a message requesting the provision of outside information captured during a predetermined time period including the date and time indicated by the event date and time information (S8).

[0059] If the consent acquisition unit 124 acquires consent for the provision of external information from a method associated with the recording device identifier identified by the identification unit 121 (Yes in S10), the information acquisition unit 125 receives external information for a specified time period including the date and time indicated by the event date and time information from the information recording device corresponding to the recording device identifier (S12).

[0060] When the information acquisition unit 125 receives the external information or consent to the provision of the external information is not obtained (No in S10), the process in this flowchart ends. The information processing device 1 repeats the above-mentioned steps 8 to 12 for all recording device identifiers identified by the identification unit 121, thereby acquiring the external information from the information recording device of the user who has consented to the information provision.

[0061] In addition, if the external information acquired by the information processing device 1 from the user's information recording device contains facts related to an event, it is preferable to obtain the user's consent again as to whether or not to provide the external information to an agency such as the police. For this reason, for example, when the extraction unit 126 extracts a vehicle registration plate from a video that is the external information, the notification unit 122 may notify the contact associated with the recording device identifier of a message for obtaining consent to provide the external information to an external agency. In this way, the information processing device 1 can prevent the external information, which is the user's private information, from being provided to an external agency without the user's consent.

[0062] <Advantages of the Information Processing Device 1 According to the Embodiment> As described above, the information processing device 1 according to the embodiment can promote the provision of information about events such as accidents. Furthermore, the information processing device 1 records date and time information and vehicle position information, which usually have a much smaller amount of data compared to video and other data, in the recorder database 100, and receives only external information for which provision is desired from the information recording device, thereby reducing the amount of data recorded in the recorder database 100 and the amount of data communicated using the communication network N.
