Description

Information Processing Apparatus, Information Processing Method, and Information Processing Program 【0001】 The present disclosure relates to an information processing apparatus, an information processing method, and an information processing program. 【0002】 Since tires for mining vehicles (hereinafter also referred to as "mining tires") travel on rough roads, there are situations where they hit, ride over, or penetrate rocks or the like that have fallen on the travel route, or when loading and unloading minerals. Due to these, the tires are likely to be damaged such as cut wounds. Continuing to use the tire in a damaged state will cause the damage to progress, leading to an early arrival of the usage limit. 【0003】 On the other hand, since mining tires are large and expensive, measures are also taken to extend the life of the tires by repairing them (hereinafter also referred to as "repair") when the damage is shallow. However, when performing repair, depending on the skills of the operator and the state of the damage, there are also tires that reach their life immediately even after repair. 【0004】 Japanese Unexamined Patent Application Publication No. 2024 - 85257 discloses a tire management device aimed at enabling long - term use of repaired tires for construction vehicles. 【0005】 This tire management device is a tire management device that manages tires mounted on a construction vehicle, and includes an acquisition unit that acquires tire management data, which is data related to the tire including repair history, and vehicle management data, which is data related to the construction vehicle used at the work site; and a determination unit that identifies the repair history of a repair target tire, which is a target for repair among the tires, based on tire ID information read from a transmitter built into the repair target tire, and determines the construction vehicle suitable for mounting so that the load on the repair target tire is reduced based on the repair history. 【0006】However, the technology disclosed in Japanese Patent Publication No. 2024-85257, while capable of extending the lifespan of repaired tires, does not involve repairing the tire itself, and therefore has the problem of not being able to effectively repair damage to the tire. This problem can occur not only with mining tires but also with other types of tires. 【0007】 This disclosure is made in view of the above circumstances and aims to provide an information processing device, an information processing method, and an information processing program that can more effectively repair damage to tires. 【0008】 The information processing device according to the first aspect of this disclosure includes: a registration unit that, for each of several existing tires that have been previously repaired for scratches, associates existing scratch image information showing an image of the scratch, repair content information showing the repair content of the scratch, and repair effect information showing the effect of the repair of the scratch with each of the scratches in the past and registers them in a storage unit in advance; an acquisition unit that acquires repair scratch image information showing an image of the scratch of a repair tire that is to be repaired; an extraction unit that derives proposed repair content information for the repair tire using the existing scratch image information showing an image of a scratch whose degree of agreement with the scratch image shown by the acquired repair scratch image information is above a predetermined threshold, and the repair content shown by the repair content information registered in the storage unit in association with the existing scratch image information showing the highest effect shown by the repair effect information registered in the storage unit in association with the existing scratch image information; and a presentation unit that presents the derived proposed information. 【0009】An information processing device according to a second aspect of the present disclosure is an information processing device according to a first aspect, wherein the registration unit further registers in the storage unit a first additional information which is at least one additional piece of information, including vehicle information indicating a vehicle on which the existing tire is fitted, mounting position information indicating the mounting position of the existing tire to the vehicle, history information indicating the history of at least one of the internal pressure and temperature of the existing tire, and load information indicating the load on the existing tire; the acquisition unit further acquires a second additional information corresponding to the additional information relating to the repair tire; and the derivation unit derives the proposed information using, in addition to the degree of agreement of the scratch image, the degree of agreement of the second additional information with respect to the first additional information as the degree of agreement. 【0010】 An information processing device according to a third aspect of this disclosure is an information processing device according to the first or second aspect, wherein the derivation unit derives the proposed information by taking into account at least one of the subsequent mileage of the repair tire, the remaining tread thickness of the repair tire, and the specifications of the repair tire. 【0011】 An information processing device according to a fourth aspect of this disclosure is an information processing device according to a third aspect, further comprising a determination unit that determines whether or not it is necessary to present the proposed information using at least one of the mileage, the remaining tread thickness, and the specifications. 【0012】 An information processing device according to the fifth aspect of this disclosure is an information processing device according to any one of the first to fourth aspects, wherein the repair content is at least one of the following repairs: repair by filling the damaged portion, repair by covering the damaged portion, and repair by cleaning the wound and then closing it. 【0013】 The information processing device according to the sixth aspect of this disclosure is an information processing device according to any one of the first to fifth aspects, wherein the repair effect information is information indicating the mileage traveled from the time of repair to disposal of the existing tire. 【0014】The information processing method according to the seventh aspect of this disclosure involves a computer pre-registering in a storage unit, for each of several existing tires that have been previously repaired for scratches, existing scratch image information showing an image of the scratch, repair content information showing the repair content of the scratch, and repair effect information showing the effect of the repair of the scratch, in association with each of the scratches. The computer then acquires repair scratch image information showing an image of the scratch of the tire to be repaired. Using the existing scratch image information showing an image of a scratch whose degree of agreement with the scratch image shown by the acquired repair scratch image information is above a predetermined threshold, and the repair content shown by the repair content information registered in the storage unit in association with the existing scratch image information showing the highest effect indicated by the repair effect information registered in the storage unit in association with the existing scratch image information, the computer derives proposed repair content information for the tire to be repaired, and presents the derived proposed information. 【0015】 The information processing program according to the eighth aspect of this disclosure pre-registers in a storage unit, for each of several existing tires that have been previously repaired for scratches, existing scratch image information showing an image of the scratch, repair content information showing the repair content of the scratch, and repair effect information showing the effect of the repair of the scratch, in association with each of the scratches. The program then acquires repair scratch image information showing an image of the scratch of the tire to be repaired. The program uses the existing scratch image information showing an image of a scratch whose degree of agreement with the scratch image shown by the acquired repair scratch image information is above a predetermined threshold, and the repair content shown by the repair content information registered in the storage unit in association with the existing scratch image information showing the highest effect indicated by the repair effect information registered in the storage unit in association with the existing scratch image information showing the highest effect, to derive proposed repair content information for the tire to be repaired, and then causes the computer to execute a process to present the derived proposed information. 【0016】 The technology disclosed herein has the effect of being able to repair tire damage more effectively. 【0017】This is a block diagram showing an example of the hardware configuration of an information processing system according to the embodiment.

This is a diagram showing an example of a suggestion information presentation screen displayed in an information processing device according to the embodiment. This is a diagram showing an example of a suggestion information presentation screen displayed in a vehicle terminal according to the embodiment. This is a cross-sectional view used to explain the problems of the prior art. 【0018】 Hereinafter, with reference to the drawings, examples of embodiments for carrying out the technology of this disclosure will be described in detail. In this embodiment, the case in which the technology of this disclosure is applied to an information processing system including an information processing device and various devices mounted on each of a plurality of vehicles equipped with the target tire will be described. Furthermore, in this embodiment, the case in which a mining tire is applied as the tire of this disclosure will be described, but the invention is not limited to this, and the tire of this disclosure can be applied to any tire, whether pneumatic or non-pneumatic. 【0019】 First, the configuration of the information processing system 90 according to this embodiment will be described with reference to Figure 1. Figure 1 is a block diagram showing an example of the hardware configuration of the information processing system 90 according to this embodiment. 【0020】 As shown in Figure 1, the information processing system 90 according to this embodiment includes an information processing device 10, each of which is able to access the network 80, and a communication device 20, a plurality of TPMS (Tire Pressure Monitoring Systems) 25, and a camera 30, each of which is mounted on a plurality of vehicles 50. Examples of information processing devices 10 include various terminal devices such as personal computers and server computers. In this embodiment, a visible light camera is used as the camera 30, but the system is not limited to this configuration, and a thermal camera may also be used as the camera 30. 【0021】The information processing device 10 according to this embodiment is a device that plays a central role in the information processing system 90. As shown in Figure 1, the information processing device 10 includes a CPU (Central Processing Unit) 11 as a computer according to this disclosure, a memory 12 as a temporary storage area, a non-volatile storage unit 13, an input unit 14 such as a keyboard and mouse, a display unit 15 such as a liquid crystal display, a media read / write device (R / W) 16, and a communication interface (I / F) unit 18. The CPU 11, memory 12, storage unit 13, input unit 14, display unit 15, media read / write device 16, and communication I / F unit 18 are connected to each other via bus B. The media read / write device 16 reads information written on the recording medium 17 and writes information to the recording medium 17. 【0022】 The storage unit 13 is implemented by an HDD (Hard Disk Drive), SSD (Solid State Drive), flash memory, etc. The storage unit 13, as a storage medium, stores an information processing program 13A. The information processing program 13A is stored (installed) in the storage unit 13 when the recording medium 17 on which the program 13A is written is set in the media read / write device 16, and the media read / write device 16 reads the program 13A from the recording medium 17. The CPU 11 reads the information processing program 13A from the storage unit 13, loads it into the memory 12, and sequentially executes the processes contained in the information processing program 13A. As a result, the CPU 11 performs information processing, which will be described in detail later. 【0023】 Furthermore, the storage unit 13 stores an existing tire information database 13B and a repair tire information database 13C. The existing tire information database 13B and the repair tire information database 13C will be described in detail later. 【0024】On the other hand, the TPMS 25 mounted on each of the multiple vehicles 50 according to this embodiment is provided corresponding to each tire of each vehicle 50. The TPMS 25 according to this embodiment includes a temperature sensor 25A that detects the internal temperature of the corresponding tire (hereinafter also referred to as "internal temperature"), a pressure sensor 25B that detects the internal pressure of the tire (hereinafter also referred to as "internal pressure"), and a transmitter 25C that is connected to these sensors and is capable of communicating with the communication device 20. The detection of internal temperature and internal pressure by the temperature sensor 25A and the pressure sensor 25B according to this embodiment is performed at a preset sampling interval. 【0025】 Furthermore, the cameras 30 mounted on each of the multiple vehicles 50 according to this embodiment are also provided to correspond to each tire of each vehicle 50 and to capture the surface of the corresponding tire to be photographed (in this embodiment, the tread and side of the tire). The camera 30 according to this embodiment comprises an imaging unit 30A that captures an image of the surface to be photographed, and a transmitter 30B that is connected to the imaging unit 30A and is capable of communicating with a communication device 20. 【0026】 On the other hand, the communication device 20 mounted on the vehicle 50 according to this embodiment is capable of communicating with the TPMS 25 and camera 30 provided on each tire of the vehicle 50, and is also capable of communicating with external devices via the network 80. Therefore, the information processing device 10 can acquire the internal temperature and internal pressure of each tire of the multiple vehicles 50, as well as image information showing captured images, via the network 80. 【0027】 Incidentally, since mining tires and the like are large and expensive, measures are taken to extend their lifespan by repairing them while the damage is still minor. However, depending on the skill of the worker performing the repair and the condition of the damage, some tires may quickly reach the end of their lifespan even after being repaired. Figure 8 shows a cross-sectional view to illustrate this problem. 【0028】For example, as shown in Figure 8, when repairing a tire by scraping away the rubber around a scratch and filling the resulting dent with unvulcanized rubber, if too much rubber is scraped away, the base may be significantly damaged, as shown in the upper right of Figure 8. Conversely, if too little rubber is scraped away, the scratch may remain, as shown in the lower right of Figure 8. If the scratch remains in this state, it may spread again. 【0029】 The information processing system 90 according to this embodiment is designed to address these problems and repair tire damage more effectively. 【0030】 Next, with reference to Figure 2, the functional configuration of the information processing device 10 according to this embodiment will be described. Figure 2 is a block diagram showing an example of the functional configuration of the information processing device 10 according to this embodiment. 【0031】 As shown in Figure 2, the information processing device 10 according to this embodiment includes a registration unit 11A, an acquisition unit 11B, a determination unit 11C, a derivation unit 11D, and a presentation unit 11E. The CPU 11 of the information processing device 10 executes the information processing program 13A, thereby enabling the acquisition unit 11B, determination unit 11C, derivation unit 11D, and presentation unit 11E to function. 【0032】 In this embodiment, the registration unit 11A pre-registers existing damage image information showing an image of the damage, repair content information showing the details of the repair, and repair effect information showing the effect of the repair for each of several tires that have been previously repaired for damage (hereinafter referred to as "existing tires") in the storage unit 13. 【0033】 The repair details shown in the repair information may include, for example, the following: 【0034】 Example 1: The rubber around the damaged area is scraped off (using a grinder, etc.), unvulcanized rubber is filled into the resulting depression, and the area is repaired by heating and pressurizing it with a tool such as an iron. 【0035】 Example 2: Repair by applying a patch made of organic fibers covered with rubber. 【0036】Example 3: In the case of a cut, the wound is repaired by cleaning the wound and applying adhesive to close it. 【0037】 On the other hand, the acquisition unit 11B according to this embodiment acquires repair damage image information showing an image of the damage to the tire to be repaired (hereinafter referred to as the "repair tire"). 【0038】 Furthermore, the derivation unit 11D according to this embodiment derives proposed repair content information for the repair tire using existing scratch image information that shows a scratch image whose degree of agreement (hereinafter simply referred to as "degree of agreement") with the scratch image shown by the repair scratch image information acquired by the acquisition unit 11B is equal to or greater than a predetermined threshold, and which has the highest effect indicated by the repair effect information registered in the storage unit 13 associated with the existing scratch image information registered in the storage unit 13 associated with the repair content information indicated by the repair content information registered in the storage unit 13. 【0039】 The presentation unit 11E according to this embodiment then presents the proposed information derived by the derivation unit 11D. 【0040】 In this embodiment, the registration unit 11A further registers in the storage unit 13 first additional information, which is additional information including vehicle information indicating a vehicle to which the existing tire is fitted, mounting position information indicating the mounting position of the existing tire on the vehicle (hereinafter referred to as "position information"), history information indicating the history of at least one (both in this embodiment) of the internal pressure and internal temperature of the existing tire, and load information indicating the load on the existing tire. 【0041】 Then, the acquisition unit 11B according to this embodiment acquires second additional information corresponding to the above additional information regarding the repair tire, and the derivation unit 11D according to this embodiment derives proposed information using, in addition to the degree of agreement of the scratch image (hereinafter referred to as "first degree of agreement"), the degree of agreement of the second additional information with respect to the first additional information (hereinafter referred to as "second degree of agreement"). 【0042】 In this embodiment, the derivation unit 11D derives proposed information by taking into account the subsequent mileage of the repair tire, the remaining tread thickness of the repair tire, and at least one (all of them in this embodiment) of the specifications of the repair tire. 【0043】 Incidentally, the above specifications correspond to information described in a catalog such as, for example, the size of a retread tire, load capacity, proper internal pressure, TKPH (tons per kilometer per hour), etc. For example, when the load capacity is large, it is considered that the tire is used for a vehicle with a large amount of cargo, so it is possible to derive proposal information that emphasizes durability even in the case of repair. 【0044】 On the other hand, the determination unit 11C according to the present embodiment determines the necessity of presenting proposal information using at least one (in this embodiment, all) of the above travel distance, the remaining tread thickness, and the above specifications. Therefore, the derivation unit 11D according to the present embodiment derives the proposal information only when it is determined by the determination unit 11C that the proposal information is to be presented. However, the present invention is not limited to this form. For example, regardless of the determination result by the determination unit 11C, the derivation unit 11D derives the proposal information, and in the presentation unit 11E, the proposal information is presented only when it is determined by the determination unit 11C that the proposal information is to be presented. 【0045】 Further, in the information processing system 90 according to the present embodiment, as the above repair content, at least one repair (in this embodiment, all repairs) of repair by embedding in the damaged part, repair by covering the damaged part, and repair by closing after washing the wound is applied. 【0046】 Further, in the information processing system 90 according to the present embodiment, as the above repair effect information, information indicating the travel distance until disposal after repair for an existing tire is applied. 【0047】 Incidentally, in the information processing system 90 according to the present embodiment, the existing tire and the retread tire are both tires mounted on the vehicle 50 included in the information processing system 90, but the present invention is not limited to this form. For example, as the existing tire, a tire mounted on a vehicle other than the vehicle 50 in the information processing system 90 may be applied, or a tire mounted on both the vehicle 50 in the information processing system 90 and a vehicle other than the vehicle 50 may be applied. 【0048】Next, referring to FIG. 3, the existing tire information database 13B according to the present embodiment will be described. FIG. 3 is a schematic diagram showing an example of the configuration of the existing tire information database 13B according to the present embodiment. 【0049】 The existing tire information database 13B according to the present embodiment is a database in which information regarding repairs performed on the above-described existing tires is registered. 【0050】 As shown in FIG. 3, the existing tire information database 13B according to the present embodiment stores a tire ID (Identification), and for each tire ID, the above-described existing damage image information, repair content information, repair effect information, vehicle information, position information, history information, and load information are stored. Here, the vehicle information, position information, history information, and load information correspond to the above-described first additional information. 【0051】 The tire ID is information that is pre-assigned as different for each of the corresponding existing tires in order to identify the existing tires. Therefore, in the existing tire information database 13B, for each existing tire, the corresponding existing damage image information, repair content information, repair effect information, vehicle information, position information, history information, and load information are stored in an associated manner. 【0052】 Next, referring to FIG. 4, the repaired tire information database 13C according to the present embodiment will be described. FIG. 4 is a schematic diagram showing an example of the configuration of the repaired tire information database 13C according to the present embodiment. 【0053】 The repaired tire information database 13C according to the present embodiment is a database in which information regarding the above-described repaired tires is registered. 【0054】As shown in Figure 4, the repair tire information database 13C according to this embodiment stores a vehicle ID and a tire ID, and for each tire ID, it stores information indicating the mileage (hereinafter referred to as "mileage information"), information indicating the remaining tread thickness (hereinafter referred to as "remaining tread thickness information"), and information indicating the specifications (hereinafter referred to as "specification information") related to the repair tire described above. Furthermore, the repair tire information database 13C according to this embodiment also stores vehicle information, location information, history information, and load information for each tire ID, similar to the information stored in the existing tire information database 13B. Here, the vehicle information, location information, history information, and load information correspond to the second additional information described above. 【0055】 The above-mentioned vehicle ID is information that is assigned to each vehicle 50 in advance, in order to identify the corresponding vehicle 50. Similarly, the above-mentioned tire ID is information that is assigned to each replacement tire in advance, in order to identify the replacement tire mounted on the corresponding vehicle 50. Accordingly, the replacement tire information database 13C stores the corresponding mileage information, remaining tread thickness information, specification information, vehicle information, location information, history information, and load information associated with each vehicle 50 and each replacement tire. 【0056】 Next, referring to Figures 5 to 7, the operation of the information processing device 10 when executing information processing will be described as the operation of the information processing system 90 according to this embodiment. Figure 5 is a flowchart showing an example of information processing according to this embodiment. The information processing shown in Figure 5 is executed when the CPU 11 of the information processing device 10 executes the information processing program 13A at a predetermined timing (in this embodiment, at 8:00 on weekdays). By executing this information processing, the information processing method of this disclosure is performed. Here, in order to avoid confusion, we will describe the case where the existing tire information database 13B and the repair tire information database 13C have already been constructed by the registration unit 11A of the information processing device 10. 【0057】In step 100 of Figure 5, the CPU 11 obtains all information (hereinafter referred to as the "existing tire information group") by reading it from the existing tire information database 13B. 【0058】 In step 102, the CPU 11 selects one of the tires of any of the vehicles 50 (hereinafter referred to as the "target vehicle") as the tire to be considered for repair (hereinafter simply referred to as the "repair tire"), and obtains all information related to that repair tire (hereinafter referred to as the "repair tire information") from the repair tire information database 13C. 【0059】 In step 104, the CPU 11 determines whether or not to present suggested information using the read repair tire information. If the determination is negative, the system proceeds to step 116; if the determination is positive, the system proceeds to step 106. In this embodiment, the determination in step 104 is made by determining whether the remaining tread thickness indicated by the remaining tread thickness information in the read repair tire information is greater than or equal to a predetermined thickness. The processing in step 104 makes it possible to avoid presenting unnecessary suggested information when the remaining usable period is short and therefore repair is not worthwhile. 【0060】 In this embodiment, the predetermined thickness is a value obtained in advance through experiments or computer simulations, which is considered to be a value for which it is not necessary to present suggested information for repair tires whose remaining tread thickness is less than that thickness. However, this is not the only form; for example, the user of the information processing device 10 may be asked to input a value corresponding to the price and frequency of use of the repair tire. 【0061】Furthermore, although the above determination is made using remaining tread thickness information in this embodiment, the method is not limited to this form, and the above determination may also be made using the subsequent mileage of the repair tire indicated by the read mileage information, or the specifications of the repair tire indicated by the read specification information. For example, in the form in which the above determination is made using the subsequent mileage of the repair tire, the determination is made by determining whether the mileage is greater than or equal to a predetermined distance. Also, for example, in the form in which the above determination is made using the specifications of the repair tire, the determination is made by determining whether the value of the repair tire indicated by the specifications is greater than or equal to a predetermined value. Furthermore, the above determination may also be made by combining multiple of the remaining tread thickness, mileage, and specifications. 【0062】 In step 106, the CPU 11 obtains repair damage image information, which shows an image of the surface of the repaired tire, from the corresponding target vehicle via the network 80. 【0063】 In step 108, the CPU 11 derives a first degree of agreement as the degree of agreement between the image of the scratch indicated by the acquired repair scratch image information and the image of the scratch indicated by all existing scratch image information included in the existing tire information group. In this embodiment, the derivation of the first degree of agreement is performed using a conventionally known pattern matching technique, but it is not limited to this form. For example, the degree of agreement may be derived using a conventionally known machine learning model. 【0064】 Furthermore, in step 108, the CPU 11 derives the degree of agreement between the second additional information in the read repair tire information and the first additional information in the existing tire information group as the second agreement degree. 【0065】In step 110, the CPU 11 identifies existing damage image information in which the derived first and second degree of matching are each above a predetermined threshold, and which has the highest effect indicated by the corresponding repair effect information (in this embodiment, the longest mileage traveled after repair until disposal). In this embodiment, the threshold is a value obtained from past performance, which indicates that the content of the repair performed on the existing tire corresponding to the existing damage image information in which the first and second degree of matching are each above that value can be considered a candidate for application to the repaired tire. However, this is not the only form, and for example, the user of the information processing device 10 may be asked to input a value corresponding to the reliability of the information registered in the existing tire information database 13B. 【0066】 In step 112, the CPU 11 creates proposed information using the repair details indicated by the repair details information corresponding to the existing damage image information identified by the processing in step 110. 【0067】 In this case, the CPU 11 creates proposal information using not only the repair details but also the mileage information, remaining tread thickness information, and specification information from the read repair tire information. For example, if the remaining tread thickness indicated by the remaining tread thickness information in the repair tire information is relatively large, it will be possible to drive long distances after the repair, so the CPU 11 creates proposal information to perform a more thorough repair. If the remaining tread thickness is relatively small, the CPU 11 creates proposal information indicating a repair that will allow driving for a certain period of time, or proposes not to perform any repairs. 【0068】 In step 114, the CPU 11 presents the created proposal information. In this embodiment, the presentation of the proposal information in step 114 is performed to the information processing device 10 and to the terminal device (hereinafter referred to as "vehicle terminal") held by the passenger of the target vehicle. 【0069】 Figure 6 shows an example of a suggestion information display screen shown in the information processing device 10 according to this embodiment. Figure 7 also shows an example of a suggestion information display screen shown in the vehicle terminal according to this embodiment. 【0070】As shown in Figure 6, the suggested information display screen in the information processing device 10 displays information identifying the target vehicle 50, information identifying the repair tire, and information indicating the repair method suggested by the suggested information. Therefore, the user of the information processing device 10 can grasp this information and take appropriate action using it. 【0071】 Furthermore, as shown in Figure 7, the suggestion information display screen on the vehicle terminal displays information identifying the repair tire on the vehicle's tires and information indicating the repair method suggested by the suggestion information. Therefore, the occupant of the vehicle can grasp this information and either directly perform the repair on the repair tire as indicated by the information, or present the repair details to the tire repair worker. 【0072】 In step 116, the CPU 11 determines whether the above processing has been completed for all tires of the target vehicle. If the determination is negative, it returns to step 102; if the determination is positive, it proceeds to step 118. When the processing in steps 102 to 116 is repeatedly executed, the CPU 11 designates any tires of the target vehicle that have not been processed so far as replacement tires. 【0073】 In step 118, the CPU 11 determines whether the above processing has been completed for all vehicles 50. If the determination is negative, it returns to step 102; if the determination is positive, it terminates this information processing. When the processing in steps 102 to 118 is repeatedly executed, the CPU 11 selects vehicles 50 that have not been processed up to that point as target vehicles. 【0074】As explained above, according to this embodiment, for each of the multiple existing tires that have been previously repaired for damage, existing damage image information showing an image of the damage, repair content information showing the repair details of the damage, and repair effect information showing the effect of the repair are pre-registered in the storage unit in association with each other. Repair damage image information showing an image of the damage of the tire to be repaired is acquired, and repair content proposal information for the tire is derived using the existing damage image information showing an image of a damage that matches the acquired repair damage image information at or above a predetermined threshold, and the existing damage image information showing the highest effect indicated by the associated repair effect information registered in the storage unit, and the repair content indicated by the associated repair content information registered in the storage unit. The derived proposal information is then presented. Therefore, for the tire to be repaired, it is possible to perform the proposed repair using the past repair content of an existing tire that has a high degree of match with its own damage and that yielded the highest repair effect, resulting in more effective repair of the tire damage. 【0075】 Furthermore, according to this embodiment, first additional information, which is at least one additional piece of information, is further registered in the storage unit, including vehicle information indicating a vehicle on which the existing tire is fitted, mounting position information indicating the mounting position of the existing tire on the vehicle, history information indicating the history of at least one of the internal pressure and temperature of the existing tire, and load information indicating the load on the existing tire. Second additional information corresponding to the above additional information regarding the repair tire is further acquired, and proposed information is derived using the degree of agreement of the second additional information with respect to the first additional information, in addition to the degree of agreement of the image of the damage. As a result, compared to the case in which the above additional information is not used as the degree of agreement, it is possible to use the repair details of the existing tire that are closer to the condition of the repair tire, and thus the damage to the tire can be repaired more effectively. 【0076】 Furthermore, according to this embodiment, the proposed information is derived by taking into account at least one of the subsequent mileage of the repaired tire, the remaining tread thickness of the repaired tire, and the specifications of the repaired tire. Therefore, compared to the case where the proposed information is derived without taking into account at least one of these factors, more meaningful proposed information can be derived, resulting in more effective repair of tire damage. 【0077】 Furthermore, according to this embodiment, the necessity of presenting proposal information is determined using at least one of the above-mentioned mileage, remaining tread thickness, and specifications. Therefore, it is possible to avoid creating or presenting unnecessary proposal information. 【0078】 Furthermore, according to this embodiment, at least one of the following repair methods is applied: repair by filling the damaged area, repair by covering the damaged area, and repair by cleaning and then closing the damaged area. Therefore, the applied repair method can be applied more effectively to the repaired tire. 【0079】 Furthermore, according to this embodiment, the repair effect information used is information indicating the mileage traveled after repair until disposal of the existing tire. Therefore, by using information indicating the mileage, which can be obtained relatively easily, as repair effect information, the proposed information can be derived more easily. 【0080】 In the above embodiment, the example described was one in which the proposed information is presented to the user of the information processing device 10 and the passengers of the vehicle 50, but the invention is not limited to this. For example, the proposed information may be presented directly to the worker performing the repair work on the tire. 【0081】 Furthermore, although the above embodiment describes a case where the necessity of presenting the proposed information is determined before the proposed information is derived, the invention is not limited to this. For example, the necessity of presenting the proposed information may be determined after the proposed information has been derived, taking into account the content of the proposal based on that information. 【0082】 Furthermore, while the above embodiment describes a case in which the proposed information is created based on at least one of the mileage information, remaining tread thickness information, and specification information in the repair tire information, it is not limited to this. For example, the proposed information may be created based on the remaining durability of the tire as described in Japanese Patent Application Publication No. 2023-131667. In this case, the necessity of presenting the proposed information and the necessity of repair may be determined based on the remaining durability. 【0083】Furthermore, while the above embodiment described the case in which it is necessary to decide whether or not to present proposal information, it is not limited to this. For example, it is also possible to always present some form of proposal information, such as suggesting that the situation be monitored without carrying out repairs, without deciding whether or not to present proposal information. 【0084】 Furthermore, although the above embodiment describes a case in which information processing is performed in the information processing device 10, the invention is not limited to this. For example, information processing may be performed by a portable terminal carried by a passenger in each vehicle 50. In this case, the information processing device of the technology of this disclosure will be included in the portable terminal. In this case, at least one of the existing tire information database 13B and the repair tire information database 13C may be built into the information processing device 10, and information processing may be performed using the built-in database. 【0085】 Furthermore, although the above embodiment described a case where one camera 30 is provided for each tire, the system is not limited to this. For example, one camera 30 may be provided for multiple tires. 【0086】 As mentioned above, a machine learning model may be used instead of rule-based pattern matching. The information processing device 10 may perform the following processing as an example of using a machine learning model. That is, the information processing device 10 may construct a training dataset based on existing damage image information, repair content information, and repair effect information registered in the existing tire information database 13B. In the training dataset, the information processing device 10 may include images of the damaged part of the tire and label information indicating the type of damage as existing damage image information. The information processing device 10 may also include at least one of the following as repair content information: text information indicating the repair work and an image of the damaged part after repair. Furthermore, the information processing device 10 may include at least one of the following as repair effect information: whether or not the repaired part has failed again and the period until the failure occurred again. 【0087】The information processing device 10 may train an image recognition model that extracts features from images of scratches indicated by the repair scratch image information using the training dataset. In this case, the information processing device 10 may use, but is not limited to, a machine learning model such as a convolutional neural network (CNN) as the image recognition model. The information processing device 10 may also set up a task to estimate repair content information and repair effect information based on the scratch images. This task may include a classification task to estimate the type of repair content, a regression task to estimate an index indicating the repair effect, or a ranking task to estimate the preference order of multiple repair content candidates. 【0088】 The information processing device 10 may generate a trained model by, for example, training an image recognition model based on a training dataset in this manner. The information processing device 10 may then input images of damage indicated by repair damage image information of a repair tire into the generated trained model and estimate a number of repair content candidates applicable to the repair tire. Furthermore, the information processing device 10 may rank the repair content candidates based on the estimation results obtained from the trained model and create proposal information as ranking information arranged, for example, in a preferred order. The information processing device 10 may then display the created proposal information. The trained model may be stored in the storage unit 13 of the information processing device 10 and used by the derivation unit 11D when deriving the proposal information. 【0089】Furthermore, in the above embodiment, for example, the hardware structure of the processing unit that executes the registration unit 11A, acquisition unit 11B, determination unit 11C, derivation unit 11D, and presentation unit 11E can be any of the following types of processors. As mentioned above, these types of processors include a CPU, which is a general-purpose processor that executes software (programs) and functions as a processing unit, as well as a programmable logic device (PLD), such as an FPGA (Field-Programmable Gate Array), which is a processor whose circuit configuration can be changed after manufacturing, and a dedicated electrical circuit, such as an ASIC (Application Specific Integrated Circuit), which is a processor with a circuit configuration specifically designed to execute a particular process. 【0090】 The processing unit may consist of one of these various processors, or it may consist of a combination of two or more processors of the same or different types (for example, a combination of multiple FPGAs, or a combination of a CPU and an FPGA). Alternatively, the processing unit may consist of a single processor. 【0091】 Examples of configuring a processing unit with a single processor include, firstly, a configuration in which one or more CPUs and software are combined to form a single processor, as is common in client and server computers, and this processor functions as the processing unit. Secondly, a configuration using a processor that realizes the functions of the entire system, including the processing unit, on a single IC (Integrated Circuit) chip, as is common in System-on-a-Chip (SoC) systems. Thus, the processing unit is configured as a hardware structure using one or more of the above-mentioned types of processors. 【0092】 Furthermore, the hardware structure of these various processors can more specifically utilize electrical circuits, which are combinations of circuit elements such as semiconductor devices. 【0093】The disclosure of Japanese Patent Application No. 2024-216948, filed on 11 December 2024, is incorporated herein by reference in its entirety. Furthermore, all documents, patent applications, and technical standards described herein are incorporated herein by reference to the same extent as if the incorporation of each individual document, patent application, and technical standard were specifically and individually noted.
