(Embodiment)
FIG. 1 is a diagram showing an example of a hardware configuration of the selection device 1 of the embodiment. The selection device 1 selects a pilot who inspects the inspection target using an unmanned aerial vehicle such as a drone. The selection device 1 includes a control unit 10 including a processor 91 such as a CPU (Central Processing Unit) connected by a bus and a memory 92, and executes a program. The selection device 1 functions as a device including a control unit 10, an input unit 11, a communication unit 12, a storage unit 13, and an output unit 14 by executing a program.

More specifically, in the selection device 1, the processor 91 reads out the program stored in the storage unit 13, and stores the read program in the memory 92. When the processor 91 executes the program stored in the memory 92, the selection device 1 functions as a device including the control unit 10, the input unit 11, the communication unit 12, the storage unit 13, and the output unit 14.

The control unit 10 controls the operation of various functional units included in the selection device 1. The control unit 10 selects, for example, a candidate for a pilot who inspects the inspection target (hereinafter referred to as “inspection pilot”). The control unit 10 records, for example, the selection result obtained by executing the program in the storage unit 13. The control unit 10 controls the operation of the output unit 14, for example, and causes the output unit 14 to output the selection result obtained by executing the program.

The input unit 11 includes an input device such as a mouse, a keyboard, and a touch panel. The input unit 11 may be configured to include an interface for connecting these input devices to its own device. The input unit 11 receives input of various information to its own device. For example, information instructing the start of operation of the selection device 1 is input to the input unit 11. For example, information related to the inspection target (hereinafter referred to as “inspection target related information”) is input to the input unit 11.

The inspection target-related information is information including at least information indicating the position of the inspection target (hereinafter referred to as “inspection target position information”). The date and time indicated by the inspection date and time information and the date and time when the inspection is carried out is, for example, the date and time when the owner to be inspected wishes to carry out the inspection.

For example, information indicating the date and time when the inspection is performed (hereinafter referred to as "inspection date and time information") is input to the input unit 11. The inspection date and time information does not necessarily have to be input to the input unit 11, and may be input to the communication unit 12 from an external device, or may be stored in the storage unit 13 in advance.

The communication unit 12 includes a communication interface for connecting the own device to an external device. The communication unit 12 communicates with the external device to be connected via wired or wireless. The external device is, for example, a terminal operated by a registered pilot (hereinafter referred to as a “pilot terminal”) such as a personal computer or a smartphone operated by the registered pilot. The registered pilot is a pilot stored in advance in the storage unit 13 as a pilot capable of operating the unmanned aerial vehicle for inspection. The registered information means the information stored in the storage unit 13. In such a case, the communication unit 12 receives, for example, the information input by the registered pilot to the pilot terminal.

The information that the registered pilot inputs to the pilot terminal may be any information as long as it is information about the registered pilot. The information that the registered pilot inputs to the pilot terminal is, for example, information indicating the position of the registered pilot itself. Hereinafter, the information indicating the position of each registered pilot is referred to as registered pilot position information.

The registered pilot position information does not necessarily have to be input via the communication unit 12, and may be input to the input unit 11. Further, the registered pilot position information does not necessarily have to be input to the input unit 11 or the communication unit 12, and may be stored in the storage unit 13 in advance. Further, the inspection target-related information and the inspection date / time information do not necessarily have to be input to the input unit 11, and may be input to the communication unit 12 from an external device.

Hereinafter, for the sake of simplicity, the selection device 1 will be described by exemplifying a case where the inspection target-related information, the inspection date and time information, and the registered pilot position information are input to the input unit 11 or the communication unit 12.

The storage unit 13 is configured by using a non-temporary computer-readable storage medium device such as a magnetic hard disk device or a semiconductor storage device. The storage unit 13 stores various information related to the selection device 1.

The output unit 14 outputs various information. The output unit 14 includes display devices such as a CRT (Cathode Ray Tube) display, a liquid crystal display, and an organic EL (Electro-Luminescence) display. The output unit 14 may be configured as an interface for connecting these display devices to its own device. The output unit 14 outputs, for example, the information input to the input unit 11. The output unit 14 may be configured to include a sound output device such as a speaker. The output unit 14 may be configured as an interface for connecting these sound output devices to the own device.

FIG. 2 is a diagram showing an example of the functional configuration of the control unit 10 in the embodiment. The control unit 10 includes an inspection-related information acquisition unit 110, a selection unit 120, a recording unit 130, and an output control unit 140.

The inspection-related information acquisition unit 110 acquires a plurality of inspection-related information including at least inspection target-related information, registered pilot position information, and inspection date / time information. That is, the inspection-related information acquisition unit 110 may acquire not only the inspection target-related information, the registered pilot position information, and the inspection date / time information, but also other inspection-related information. The inspection-related information is information related to the inspection. Therefore, the inspection target-related information, the registered pilot position information, and the inspection date / time information are examples of inspection-related information.

The inspection-related information acquisition unit 110 acquires inspection-related information via the input unit 11 or the communication unit 12. When the inspection target-related information is stored in the storage unit 13, the inspection-related information acquisition unit 110 reads the inspection target-related information stored in the storage unit 13 from the storage unit 13.

Hereinafter, a process in which the inspection-related information acquisition unit 110 acquires a plurality of inspection-related information including at least inspection target-related information, registered pilot position information, and inspection date / time information is referred to as an inspection-related information acquisition process.

The selection unit 120 selects an inspection pilot candidate from the registered pilots based on the inspection-related information acquired by the inspection-related information acquisition unit 110. The inspection pilot candidate is a candidate for an inspection pilot who inspects the inspection target at the date and time indicated by the inspection date and time information. More specifically, the selection unit 120 selects inspection pilot candidates based on at least the inspection target position information and the registered pilot position information. For the sake of simplicity of the following description, the selection device 1 will be described by taking the case where the inspection target related information includes only the inspection target position information as an example.

The selection unit 120 selects, for example, the registered pilot whose position indicated by the registered pilot position information is closest to the position indicated by the inspection target position information as an inspection pilot candidate. The selection unit 120 selects up to a predetermined number of registered pilots as inspection pilot candidates in the order in which the position indicated by the registered pilot position information is close to the position indicated by the inspection target position information.

The selection unit 120 does not necessarily have to select the inspection pilot candidate only based on the inspection target-related information, the registered pilot position information, and the inspection date / time information. The selection unit 120 may select an inspection pilot candidate based on other inspection-related information in addition to the inspection target-related information, the registered pilot position information, and the inspection date / time information. An example of processing of the selection unit 120 when selecting an inspection pilot candidate based on other inspection-related information will be described in a modified example. Hereinafter, the process in which the selection unit 120 selects the inspection pilot candidate based on the inspection-related information is referred to as a selection process.

The recording unit 130 records various information generated by the processing of the control unit 10 in the storage unit 13. The recording unit 130 records, for example, information indicating an inspection pilot candidate in the storage unit 13.

The output control unit 140 controls the operation of the output unit 14. The output control unit 140 controls the operation of the output unit 14 to output, for example, information indicating an inspection pilot candidate by a method such as display.

FIG. 3 is a flowchart showing an example of the flow of processing executed by the selection device 1 in the embodiment.
The inspection-related information acquisition unit 110 acquires a plurality of inspection-related information including at least inspection target-related information, registered pilot position information, and inspection date / time information (step S101). Next, the selection unit 120 selects an inspection pilot candidate based on the inspection-related information acquired in step S101 (step S102). Next, the output control unit 140 controls the operation of the output unit 14 to output the information indicating the inspection pilot candidate of the selection result to the output unit 14 (step S103).

The selection device 1 of the embodiment configured in this way selects inspection pilot candidates based on a plurality of inspection-related information including at least inspection target-related information, registered pilot position information, and inspection date / time information. Therefore, the selection device 1 can assist in determining the schedule of inspection work using the unmanned aerial vehicle.

(Modification example)
The number of inspection pilot candidates selected by the selection unit 120 may not be one but may be plural. Therefore, the selection device 1 is a device for selecting N inspection pilot candidates (N is the number of inspection pilot candidates and is an integer of 1 or more). The date and time indicated by the inspection date and time information may not be one but may be plural.

As described above, the selection unit 120 does not need to select the inspection pilot candidate only based on the inspection target-related information, the registered pilot position information, and the inspection date / time information. The selection unit 120 may further select inspection pilot candidates using other inspection-related information. In such a case, the inspection pilot candidate is selected using, for example, a selection index. The selection index is a predetermined index whose value is determined according to the combination of the contents of each inspection-related information. The value of the selection index is, for example, the value of a predetermined function having a numerical value representing each content of inspection-related information as an independent variable.

When there are a plurality of registered pilots having the same selection index value and N = 1, the selection unit 120 executes the next-stage selection process. In the next-stage selection process, the selection process is executed again for the registered pilots with the same selection index value, using only the inspection-related information from the one with the highest importance to the predetermined number. The importance ranking is a predetermined ranking for the importance of each inspection-related information. By repeating this process, the selection unit 120 selects one inspection pilot candidate from the registered pilots having the same selection index value.

An example of processing of the selection unit 120 when there are a plurality of registered pilots having the same selection index value has been described by taking the case of N = 1, but the number of registered pilots having the same selection index value has been described. The same applies to the case where is larger than N.

If the number of registered pilots whose all inspection-related information has the same content is larger than N, a random number generator may be used to determine N inspection pilot candidates.

The inspection target-related information may be, for example, information indicating the size of the inspection target (hereinafter referred to as “inspection target size information”). The inspection target size information may indicate, for example, the total length of the inspection target. The inspection target size information may indicate, for example, the smallness of the inspection target. The inspection target-related information may include, for example, information indicating the conditions satisfied by the inspection target portion. The condition satisfied by the part to be inspected is, for example, information that the part to be inspected is a rusted part. The inspection target-related information may include, for example, information indicating the type of inspection target (hereinafter referred to as “inspection target type information”). The inspection target type information may indicate, for example, that the inspection target is a bridge, or may indicate, for example, that the inspection target is a steel tower.

One of the inspection-related information acquired by the inspection-related information acquisition unit 110 may be, for example, information indicating the performance of the unmanned aerial vehicle operated by each registered pilot (hereinafter referred to as “unmanned aerial vehicle performance information”). In such a case, the selection unit 120 may use the unmanned aerial vehicle performance information as one of the inspection-related information in addition to the inspection target-related information, the registered pilot position information, and the inspection date / time information in the selection process.

The performance of the unmanned aerial vehicle indicated by the unmanned aerial vehicle performance information is, for example, the maximum speed. The performance of the unmanned aerial vehicle indicated by the unmanned aerial vehicle performance information may be, for example, the resolution of the mounted camera.

An example of the operation of the selection unit 120 when the unmanned aerial vehicle performance information is included in one of the inspection-related information acquired by the inspection-related information acquisition unit 110 will be described. In particular, an example of the operation of the selection unit 120 will be described by taking the case where the first explanatory condition and the second explanatory condition are satisfied as an example. The first explanatory condition is that the inspection target-related information includes only information indicating how small the size of the inspection target is (hereinafter referred to as "inspection target size information"). The second explanatory condition is that there are a plurality of inspection pilot candidates having the same selection index value.

When the first explanatory condition and the second explanatory condition are satisfied, the selection unit 120 determines the operator of the unmanned aerial vehicle equipped with a camera capable of shooting the inspection target at a resolution higher than a predetermined resolution based on the inspection target size information. Select a pilot as an inspection pilot candidate with priority over other pilots.

One of the inspection-related information acquired by the inspection-related information acquisition unit 110 may be, for example, weather information (hereinafter referred to as “weather information”). In such a case, the selection unit 120 may use the weather information as one of the inspection-related information in addition to the inspection target-related information, the registered pilot position information, and the inspection date / time information in the selection process.

The weather information is acquired from a computer of an organization that provides information on the weather, such as the Japan Meteorological Agency, via, for example, the communication unit 12. For example, when the inspection date and time information indicates a plurality of dates and times and the weather information indicates that a storm will occur at the position to be inspected at one of the dates and times indicated by the inspection date and time information, the selection unit 120 causes a storm. Select inspection pilot candidates only on days other than the date and time.

One of the inspection-related information acquired by the inspection-related information acquisition unit 110 may be, for example, information indicating the number of years of experience of the registered pilot (hereinafter referred to as “years of experience information”). In such a case, the selection unit 120 may use the inspection target-related information, the registered pilot position information, the inspection date / time information, and the years of experience information as one of the inspection-related information in the selection process.

When the contents of the inspection-related information other than the years of experience of the registered pilot are the same, the selection unit 120 selects, for example, a registered pilot with less years of experience as an inspection pilot candidate based on the years of experience information. By making such a selection, it is possible to raise the level of inspection technology for a group of registered pilots. If the content of inspection-related information other than the years of experience of the registered pilot is the same, the selection unit 120 selects, for example, a registered pilot with more years of experience as an inspection pilot candidate based on the years of experience information. May be good.

One of the inspection-related information acquired by the inspection-related information acquisition unit 110 may be, for example, information indicating the achievements of the registered pilot (hereinafter referred to as “actual information”). In such a case, the selection unit 120 may use the performance information as one of the inspection-related information in addition to the inspection target-related information, the registered pilot position information, and the inspection date / time information in the selection process.

When the contents of inspection-related information other than the actual information are the same, the selection unit 120 selects a registered pilot with a better achievement as an inspection pilot candidate, for example, according to the type of inspection target. For example, if the type of inspection target is a bridge, the selection unit 120 selects a registered pilot who has a better track record in inspecting the bridge as an inspection pilot candidate.

It should be noted that the quality of the actual results is determined by the selection unit 120 based on the results of inspections performed by the registered pilots in the past, for example, according to a predetermined rule. For example, the selection unit 120 determines whether the registered pilot's performance is good or bad depending on whether or not the image taken by the registered pilot in the past inspection has an image quality satisfying a predetermined criterion.

The results of inspections performed by previously registered pilots may include, for example, images taken by registered pilots in past inspections. The result of the inspection performed by the registered pilot in the past may include, for example, a three-dimensional image of the inspection target generated based on the image taken by the registered pilot in the past inspection.

The content of the performance information is, for example, a questionnaire conducted to customers who have been inspected by one or more registered pilots in the past, and a questionnaire in which each registered pilot answers the degree of satisfaction. The result of may be included.

The selection device 1 may be mounted as the selection system 100 by using a plurality of information processing devices connected so as to be able to communicate via a network. In this case, each functional unit included in the selection device 1 may be distributed and mounted in a plurality of information processing devices. For example, the inspection-related information acquisition unit 110 and the selection unit 120 may be distributed and mounted in different information processing devices.

FIG. 4 is a diagram showing an example of the system configuration of the selection system 100 in the modified example. The selection system 100 includes an inspection-related information acquisition processing execution device 101 and a selection processing execution device 102 connected via a network. The inspection-related information acquisition process execution device 101 includes an inspection-related information acquisition unit 110, and executes the inspection-related information acquisition process. The selection process execution device 102 includes a selection unit 120 and executes a selection process.

All or part of each function of the selection device 1 and the selection system 100 is realized by using hardware such as ASIC (Application Specific Integrated Circuit), PLD (Programmable Logic Device), and FPGA (Field Programmable Gate Array). You may. The program may be recorded on a computer-readable recording medium.
