Description

Wearable device and photography control method

[0001] The present disclosure relates to a wearable device and a photography control method.

[0002] For example, a technology for capturing images of on-site workers working using a wearable device carried by the workers has been known for some time. However, when capturing images of on-site work using such a wearable device, a problem arises in that the battery of the wearable device runs out.

[0003] Patent Document 1 describes a technique for reducing the power consumed by a head-mounted display by lowering the resolution of an image captured by a camera module.

[0004] Japanese Patent Application Laid-Open No. 2020-96285

[0005] For example, in an information processing system that uses video captured by a wearable device carried by a field worker to support field work or secure evidence of field work, the captured data may continue to be saved or transmitted not only while the field worker is working near the equipment that is the target of the work, but also while the field worker is away from the equipment (for example, while the field worker moves from the location where the equipment that is the target of the work is installed to his / her car to get his / her tools).

[0006] If the on-site worker continues to save or transmit image data even when the worker is far from the facility equipment, the battery consumption of the wearable device increases compared to when the worker stops saving or transmitting image data during the time when the worker is far from the facility equipment. When stopping saving or transmitting image data during the time when the worker is far from the facility equipment, the on-site worker has to go through the trouble of starting and stopping the saving or transmission of the image data. When stopping image capture during the time when the worker is far from the facility equipment, the on-site worker has to go through the trouble of starting and stopping the image capture. Furthermore, it has often been difficult to determine, using a uniform rule, whether the on-site worker is working near the facility equipment or far from the facility equipment, and then control the start and stop of image capture, the start and end of saving the image data, or the start and end of transmitting the image data. Patent Document 1 does not describe such issues.

[0007] The present disclosure aims to provide a wearable device and a photography control method that reduce battery consumption in a wearable device that is carried by a field worker and captures images of the field work performed by the field worker.

[0015] According to a fourth aspect of the present disclosure, after stopping shooting, ending saving of shooting data, or ending transmission of shooting data, if you approach within a predetermined range from the shooting position, you can resume shooting, restart saving of shooting data, or restart transmission of shooting data.

[0016] A fifth aspect of the present disclosure is the wearable terminal of the fourth aspect, wherein the control unit records, in the storage unit, a plurality of shooting positions at the time of starting to save or start to transmit the shooting data.

[0017] According to a fifth aspect of the present disclosure, by recording multiple shooting locations at the time when saving or transmission of shooting data begins, when approaching within a predetermined range of any of the multiple shooting locations, saving of the shooting data or transmission of the shooting data can be resumed.

[0018] A sixth aspect of the present disclosure is a wearable terminal described in any one of the first to fifth aspects, wherein the control unit starts saving the photographed data or starts transmitting the photographed data in accordance with an operation by the field worker.

[0019] According to the sixth aspect of the present disclosure, the saving of the photographed data or the transmission of the photographed data can be started in accordance with the operation of the field worker.

[0020] A seventh aspect of the present disclosure is a wearable terminal according to any one of the first to sixth aspects, wherein the control unit controls the notification unit to notify the field worker of the start of the shooting, the end of the shooting, the start of saving the shooting data, the end of saving the shooting data, the start of transmission of the shooting data, or the end of transmission of the shooting data.

[0021] According to the seventh aspect of the present disclosure, a field worker can be notified of the start of photography, the end of photography, the start of saving the photography data, the end of saving the photography data, the start of transmitting the photography data, or the end of transmitting the photography data.

[0022] An eighth aspect of the present disclosure is a wearable terminal described in any one of the first to seventh aspects, wherein the control unit, while continuing the photographing, terminates saving of the photographed data or terminates transmission of the photographed data based on the deviation.

[0027] Next, embodiments of the present disclosure will be described in detail.

[0028] 1 is a configuration diagram of an example of an information processing system 1 according to this embodiment. The information processing system 1 shown in FIG. 1 includes a wearable device 10, an information processing device 20, and an analysis operator terminal 30.

[0029] The wearable device 10 is a device carried by or worn by a field worker performing field work at the field site 2. The wearable device 10 carried by or worn by the field worker can capture video from the field worker's first-person perspective. The video from the field worker's first-person perspective may be video captured in the field worker's line of sight, or may be video captured in front of the field worker.

[0030] For example, the wearable terminal 10 is worn at any location, such as on the field worker's arm, around the eyes, around the ears, or around the neck, or on clothing worn by the field worker. The wearable terminal 10 may be a dedicated terminal or a smartphone with a dedicated application installed. The dedicated terminal of the wearable terminal 10 is, for example, a neck-worn wearable terminal 10 worn around the neck of the field worker to capture video from the field worker's first-person perspective. The smartphone with the dedicated application installed may be attached to the field worker by, for example, a smartphone harness or a smartphone holder. In this embodiment, a neck-worn wearable terminal 10 worn around the neck of the field worker to capture video from the field worker's first-person perspective will be described as an example.

[0031] The wearable terminal 10 is communicatively connected to the information processing device 20 via a network 50. The wearable terminal 10 may be communicatively connected to the information processing device 20 via the network 50 by using a communication function of a mobile terminal such as a smartphone of a field worker. The network 50 is, for example, the Internet. The network 50 may also be a local area network (LAN) or a dedicated communication line.

[0032] The wearable terminal 10 has a control unit 12. The control unit 12 is a hardware configuration that executes programs, such as a central processing unit (CPU), an application specific integrated circuit (ASIC), or a field programmable gate array (FPGA). The CPU, which is an example of the control unit 12, executes programs, allowing the wearable terminal 10 to perform various processes, which will be described later.

[0033] The information processing device 20 is communicably connected to the wearable terminal 10 and the analysis operator terminal 30 via a network 50. The information processing device 20 receives data (photographed data) of moving images or still images captured by the wearable terminal 10. The information processing device 20 stores the photographed data received from the wearable terminal 10. The information processing device 20 may use the stored photographed data, for example, for annotation work processing or remote support processing.

[0034] The information processing device 20 also has a control unit 22. The control unit 22 is a hardware configuration that executes programs, such as a CPU, an ASIC, or an FPGA. For example, the information processing device 20 can perform various processes described below by having a CPU, which is an example of the control unit 22, execute the programs.

[0035] The analysis worker terminal 30 is a device operated by an analysis worker such as an annotator or a remote supporter to process the captured data stored in the information processing device 20. The analysis worker terminal 30 is equipped with various tools used by the analysis worker, such as annotation tools or remote support tools.

[0036] The analysis worker operates the analysis worker terminal 30 to perform annotation work or remote support. The analysis worker terminal 30 accepts a request from the analysis worker and transmits the request to the information processing device 20. The analysis worker terminal 30 receives a response to the request from the information processing device 20 and displays the response.

[0037] The analysis operator terminal 30 is a hardware configuration that executes a program and includes a control unit such as a CPU, an ASIC, or an FPGA. The analysis operator terminal 30 can perform various processes described below by having the CPU, which is an example of a control unit, execute the program.

[0038] The information processing device 20 is, for example, a personal computer (PC) or a workstation. The information processing device 20 may be realized by using an application service provider (ASP) or cloud computing. The analysis operator terminal 30 is, for example, a PC, a smartphone, or a tablet terminal.

[0039] 1 is an example. For example, the information processing system 1 may be configured with one or more information processing devices 20. It goes without saying that the information processing system 1 may have various system configuration examples depending on the application and purpose.

[0040] <Device Configuration> The information processing device 20 in Fig. 1 is realized, for example, by a computer 500 having the hardware configuration shown in Fig. 2. Furthermore, the analysis operator terminal 30 in Fig. 1 may be realized by the computer 500 having the hardware configuration shown in Fig. 2.

[0041] 2 is a diagram showing an example of the hardware configuration of a computer 500 according to this embodiment. The computer 500 includes an input device 501, a display device 502, an external I / F 503, a RAM (Random Access Memory) 504, a ROM (Read Only Memory) 505, a CPU 506, a communication I / F 507, and an HDD (Hard Disk Drive) 508, all of which are interconnected by a bus B. The input device 501 and the display device 502 may be connected and used when necessary.

[0042] The input device 501 is a touch panel, operation keys, buttons, a keyboard, a mouse, etc. The display device 502 is composed of a display that displays a screen, a speaker that outputs sound, etc.

[0043] The communication I / F 507 is an interface through which the computer 500 communicates data via the network 50. The HDD 508 is an example of a non-volatile storage device that stores programs and data. The programs and data include an operating system (OS), which is basic software that controls the entire computer 500, and applications that provide various functions on the OS. The computer 500 may use a solid state drive (SSD) instead of the HDD 508.

[0044] The external I / F 503 is an interface with an external device. The external device may be a recording medium 503a. The computer 500 reads and writes data from and to the recording medium 503a via the external I / F 503.

[0045] The recording medium 503a is a flexible disk, a CD (Compact Disc), a DVD (Digital Versatile Disc), an SD (Secure Digital) memory card, a USB (Universal Serial Bus) memory, or the like.

[0046] The ROM 505 is an example of a non-volatile semiconductor memory (storage device) that can retain programs and data even when the power is turned off. The ROM 505 stores programs and data such as a Basic Input Output System (BIOS) that is executed when the computer 500 starts up, OS settings, and network settings. The RAM 504 is an example of a volatile semiconductor memory (storage device) that temporarily retains programs and data.

[0047] The CPU 506 is a computing device that reads programs and data from a storage device such as the ROM 505 or the HDD 508 onto the RAM 504 and executes processing to realize overall control and functions of the computer 500. The CPU 506 is an example of the control unit 22 of the information processing device 20 and an analysis control unit.

[0048] The wearable terminal 10 of Fig. 1, for example, in the case of a neck-worn type wearable terminal 10, is realized by the hardware configuration shown in Fig. 3 and Fig. 4. Fig. 3 is an external view of an example of the wearable terminal 10 according to the present embodiment. Fig. 4 is a functional configuration diagram of an example of the wearable terminal 10 according to the present embodiment.

[0049] The housing that constitutes the wearable terminal 10 includes a left arm section 110, a right arm section 120, and a main body section 130. The left arm section 110 and the right arm section 120 extend forward from the left end and the right end of the main body section 130, respectively. The wearable terminal 10 has a structure that forms a roughly U-shape as a whole when viewed from above. For example, when a field worker, who is an example of a wearer, puts on the wearable terminal 10, the main body section 130 touches the back of the neck and the left arm section 110 and the right arm section 120 hang down from the side of the neck toward the chest, and the device is hooked around the neck.

[0050] The left arm 110 and the right arm 120 are each provided with a plurality of sound collection units 141 to 145. The sound collection units 141 to 145 are, for example, microphones. The sound collection units 141 to 145 are arranged mainly for the purpose of acquiring the voices of the wearer and the interlocutor. The sound collection units 141 and 142 are provided on the left arm 110. The sound collection units 143 and 144 are provided on the right arm 120. The left arm 110 and the right arm 120 may be provided with one or more additional sound collection units.

[0051] 3, in addition to the sound collection units 141 and 142, a sound collection unit 145 is provided on the left arm 110. The sound signals acquired by the sound collection units 141 to 145 are transmitted to the control unit 12 provided in the main body 130, where predetermined processing is performed. For example, the sound signals acquired by the sound collection units 141 to 145 are used to control the imaging unit 160 by voice recognition, such as starting imaging, stopping imaging, starting saving of the image data, ending saving of the image data, starting transmission of the image data, and ending transmission of the image data.

[0052] The left arm 110 is further provided with an imaging unit 160. The imaging unit 160 is provided on the distal end surface 112 of the left arm 110. The imaging unit 160 captures video and still images of the front side of the site worker. The image data captured by the imaging unit 160 is transmitted to the control unit 12 in the main body 130. The image data captured by the imaging unit 160 is stored in, for example, the storage unit 181. The wearable terminal 10 may also transmit the image data captured by the imaging unit 160 to, for example, the information processing device 20 for storage.

[0053] The right arm 120 is further provided with a non-contact sensor unit 170. The sensor unit 170 is disposed on a distal end surface 122 of the right arm 120 in order to detect, for example, the movement of the hand of the field worker. The detection information of the sensor unit 170 is used to control the imaging unit 160, such as the start of imaging, the stop of imaging, the start of saving the imaged data, the end of saving the imaged data, the start of transmitting the imaged data, and the end of transmitting the imaged data.

[0054] For example, the sensor unit 170 may control the imaging unit 160 by detecting the proximity of a hand or the like of a field worker, or may control the imaging unit 160 by detecting a predetermined gesture made by the field worker within the detection range of the sensor unit 170. Note that in this embodiment, the imaging unit 160 is arranged on the distal end surface 112 of the left arm 110, and the sensor unit 170 is arranged on the distal end surface 122 of the right arm 120, but the positions of the imaging unit 160 and the sensor unit 170 may be interchanged.

[0055] The wearable terminal 10 may also use the detection information of the sensor unit 170 to activate at least one of the image capture unit 160, the sound collection units 141 to 145, and the control unit 12. For example, in a state in which the sensor unit 170, the sound collection units 141 to 145, and the control unit 12 are always active and the image capture unit 160 is stopped, the wearable terminal 10 may activate the image capture unit 160 when the sensor unit 170 detects a specific gesture. For example, in a state in which the sensor unit 170, the sound collection units 141 to 145, and the control unit 12 are always active and the image capture unit 160 is stopped, the wearable terminal 10 may activate the image capture unit 160 when the sound collection units 141 to 145 detect a specific sound.

[0056] 4, the left arm 110 is provided with a sound collection unit 141, a sound collection unit 142, a sound collection unit 145, an operation unit 150, and an imaging unit 160. The right arm 120 is provided with a sound collection unit 143, a sound collection unit 144, and a sensor unit 170. The main body 130 is provided with a control unit 12, a memory unit 181, a communication unit 182, a proximity sensor 183, a notification unit 184, a gyro sensor 185, an acceleration sensor 186, and a battery 190. In addition to the functional configuration shown in FIG. 4, the wearable terminal 10 may be equipped with sensors such as a geomagnetic sensor or a GPS sensor as appropriate.

[0057] The sound collection units 141 to 145 can use known microphones such as a dynamic microphone, a condenser microphone, a MEMS (Micro-Electrical-Mechanical Systems) microphone, etc. The sound collection units 141 to 145 convert sound into an electrical signal, which is then converted into digital information by an A / D conversion circuit and transmitted to the control unit 12.

[0058] The operation unit 150 accepts operation inputs from the field worker. The operation unit 150 can be, for example, a known switch circuit or touch panel. The operation unit 150 accepts, from the field worker, operations to instruct power on or off, and operations necessary to realize the functions of the wearable terminal 10. The operation unit 150 may also accept, from the field worker, operations to control the imaging unit 160, such as starting image capture, stopping image capture, starting saving of captured data, ending saving of captured data, starting transmission of captured data, and ending transmission of captured data. Information input via the operation unit 150 is sent to the control unit 12.

[0059] The imaging unit 160 captures moving images or still images. For example, a general digital camera may be used as the imaging unit 160. The imaging data captured by the imaging unit 160 is transmitted to the control unit 12. The imaging data captured by the imaging unit 160 may be stored in the storage unit 181. The imaging data captured by the imaging unit 160 may also be transmitted to the information processing device 20 and stored in the information processing device 20.

[0060] In this embodiment, the start of image capture by the image capture unit 160 does not necessarily mean the start of storage of the captured image data in the storage unit 181 or the start of transmission to the information processing device 20. The timing of starting storage of the captured image data in the storage unit 181 or the timing of starting transmission to the information processing device 20 is managed separately from the timing of starting image capture by the image capture unit 160.

[0061] The sensor unit 170 is a non-contact detection device for detecting the movement of the worker's fingers, etc. The sensor unit 170 is, for example, a proximity sensor or a gesture sensor. The proximity sensor detects, for example, when the worker's fingers approach within a predetermined range. The proximity sensor may be a known type such as an optical type, an ultrasonic type, a magnetic type, a capacitance type, or a thermal type.

[0062] The gesture sensor detects, for example, the movement and shape of the fingers of a field worker. The gesture sensor is, for example, an optical sensor that detects, for example, the movement and shape of the fingers of a field worker by irradiating an object with light from an infrared-emitting LED and capturing changes in the reflected light with a light-receiving element. Detection information by the sensor unit 170 is transmitted to the control unit 12 and used to control the image capture unit 160, such as starting image capture, stopping image capture, starting saving of image capture data, ending saving of image capture data, starting transmission of image capture data, and ending transmission of image capture data.

[0063] The sensor unit 170 generally consumes little power, and is therefore preferably kept running at all times while the power of the wearable terminal 10 is on. Alternatively, the sensor unit 170 may be started when the proximity sensor 183 detects that the wearable terminal 10 is being worn.

[0064] The control unit 12 performs arithmetic processing to control the wearable terminal 10. The control unit 12 can use a processor such as a CPU. The control unit 12 reads out a program stored in the storage unit 181 and executes predetermined arithmetic processing in accordance with the program. The control unit 12 also writes and reads out the results of the arithmetic processing in accordance with the program to and from the storage unit 181.

[0065] The memory unit 181 stores information used for arithmetic processing and the like in the control unit 12, and the results of the arithmetic processing. The storage function of the memory unit 181 can be realized by a non-volatile memory such as an HDD or SSD. The memory unit 181 may also function as a memory for writing or reading intermediate data of arithmetic processing by the control unit 12. The memory function of the memory unit 181 can be realized by a volatile memory such as a RAM or DRAM.

[0066] The communication unit 182 may employ a communication module for wireless communication according to a known mobile communication standard such as 3G (W-CDMA), 4G (LTE / LTE-Advanced), or 5G. The communication unit 182 may employ a communication module for wireless communication according to a wireless LAN system such as Wi-Fi (registered trademark). The communication unit 182 may also employ a communication module for close proximity wireless communication according to a system such as Bluetooth (registered trademark) or NFC.

[0067] The proximity sensor 183 is disposed inside the main body 130 and detects when the neck of the field worker approaches within a predetermined range. The notification unit 184 notifies the field worker by sound, light, or vibration. The notification unit 184 is, for example, a speaker, an LED, or a vibration motor. The notification unit 184 notifies the field worker by sound from a speaker, light from an LED, or vibration from a vibration motor. The notification unit 184 notifies the field worker of the start of imaging, the end of imaging, the start of saving the imaged data, the end of saving the imaged data, the start of transmission of the imaged data, or the end of transmission of the imaged data. The notification unit 184 may be a bone conduction speaker that notifies the field worker by vibrating the field worker's bones.

[0068] The gyro sensor 185 detects a change in rotation or orientation of the wearable terminal 10 as an angular velocity. For example, the gyro sensor 185 predicts the shooting direction of the wearable terminal 10 from the detected angular velocity. Furthermore, the acceleration sensor 186 detects the acceleration of the wearable terminal 10. For example, the acceleration sensor 186 predicts the shooting position of the wearable terminal 10 from the detected acceleration.

[0069] The battery 190 supplies power to various electronic components included in the wearable terminal 10. The battery 190 may be a rechargeable battery such as a lithium ion battery, a lithium polymer battery, an alkaline storage battery, a nickel-cadmium battery, a nickel-metal hydride battery, or a lead storage battery.

[0070] <Processing> In this embodiment, a field worker performing field work at the field site 2 carries or wears the wearable device 10 and captures video of the field work. The video of the field work captured by the wearable device 10 is video from the field worker's first-person perspective. In this embodiment, an example of field work related to an air conditioner in a house will be described as an example of field work performed at the field site 2.

[0071] FIG. 5 is a diagram illustrating an example of on-site work related to an air conditioner performed in a home. The floor plan shown in FIG. 5 represents a portion of the floor plan of a home where on-site work related to an air conditioner is performed. An indoor unit 1000 of the air conditioner is installed in a room (e.g., a bedroom) of the home. An outdoor unit 1002 of the air conditioner is installed outside the home. For example, a worker performs on-site work related to the air conditioner while moving back and forth between the indoor unit 1000 and the outdoor unit 1002 along a flow line 1020.

[0072] An area 1010 indicated by a dotted line indicates a first work area where on-site work is performed on the indoor unit 1000. An area 1012 indicated by a dotted line indicates a second work area where on-site work is performed on the outdoor unit 1002. The first work area and the second work area are examples of work areas where a first-person perspective video of a on-site worker captured by the wearable terminal 10 is desired to be recorded.

[0073] In the first-person viewpoint video of the field worker captured by the wearable device 10, captured data of the range visible from the field worker's movement path 1020 may be stored, which is undesirable from the viewpoint of privacy. Furthermore, it is a burden for the field worker to operate the wearable device 10 to control the start and end of saving or transmitting the captured data every time the field worker moves back and forth between the indoor unit 1000 and the outdoor unit 1002 along the movement path 1020.

[0074] Therefore, in this embodiment, an operation to start saving or transmitting the first captured image data in the first work area and the second work area is accepted from the field worker. After starting saving or transmitting the captured image data, the wearable device 10 determines a deviation from the capture position or capture direction at which saving or transmitting the captured image data was started, and automatically stops capturing, ends saving of the captured image data, or ends transmission of the captured image data based on the deviation. The wearable device 10 may determine a deviation from the capture position and capture direction at which saving or transmitting the captured image data was started, and automatically stops capturing, ends saving of the captured image data, or ends transmission of the captured image data based on the deviation.

[0075] In addition, in this embodiment, when the camera approaches within a specified range from the shooting location where the saving or transmission of the first shooting data began, the saving or transmission of the second and subsequent shooting data in the first working area and the second working area is automatically resumed.

[0076] In addition, it is generally difficult to determine whether the photographic data was taken in the first work area and the second work area using a uniform rule, because the installation locations of the indoor unit 1000 and the outdoor unit 1002 vary depending on the house.

[0077] In this way, in this embodiment, it is possible to determine a deviation from the imaging position or imaging direction at which saving or transmitting of imaging data was started, and to automatically stop imaging, end saving of imaging data, or end transmission of imaging data based on the deviation. Also, in this embodiment, it is possible to determine a deviation from the imaging position and imaging direction at which saving or transmitting of imaging data was started, and to automatically stop imaging, end saving of imaging data, or end transmission of imaging data based on the deviation. Therefore, in this embodiment, it is possible to store or transmit imaging data in the first work area and the second work area, and to control imaging so that imaging data in a range visible from the flow line 1020 of the on-site worker is not stored or transmitted.

[0078] In this embodiment, photography is controlled so that photographed data from areas other than the first work area and the second work area is not saved or transmitted, which reduces battery consumption of the wearable device 10 compared to continuing to save or transmit photographed data from areas other than the first work area and the second work area. For example, a field worker who is in charge of multiple work sites 2 per day can save or transmit photographed data for a longer period of time by using the wearable device 10 according to this embodiment than with a wearable device 10 that continues to save or transmit photographed data from areas other than the first work area and the second work area. Furthermore, the saved or transmitted photographed data from the first work area and the second work area can be used to support work on site or to secure evidence of work on site.

[0079] In this embodiment, the following processing is provided to control photography so that photographed data within a range visible from the path 1020 along which the field worker moves is not saved or transmitted.

[0080] Fig. 6 is a flowchart of an example of the photographing control process according to this embodiment. Figs. 7A to 7E are explanatory diagrams of an example of the photographing control process according to this embodiment. The wearable device 10 in Figs. 7A to 7E is carried or worn by a field worker.

[0081] In step S10, the control unit 12 of the wearable device 10 carried or worn by the field worker receives an operation input by the field worker to start capturing images, and starts capturing images using the imaging unit 160. The operation input by the field worker to start capturing images may be an operation input to the operation unit 150, voice recognition using sound signals acquired by the sound collection units 141 to 145, or detection of a specific gesture by the sensor unit 170.

[0082] Note that even though the wearable terminal 10 starts capturing images using the imaging unit 160 in step S10, it has not started storing the captured image data in the storage unit 181 or transmitting the captured image data to the information processing device 20. Fig. 7A shows the wearable terminal 10 in a state where it has started capturing images using the imaging unit 160 but has not started storing the captured image data in the storage unit 181 or transmitting the captured image data to the information processing device 20.

[0083] In step S12, the control unit 12 of the wearable terminal 10 determines whether or not it has received an input from the field worker to start saving or transmitting the captured image data. The input from the field worker to start saving or transmitting the captured image data may be an input from the operation unit 150, voice recognition using sound signals acquired by the sound collection units 141 to 145, or detection of a specific gesture by the sensor unit 170. Note that in step S12, the control unit 12 may determine that the timing when a measuring device connects to the wearable terminal 10 via Bluetooth (registered trademark) or the like is the timing when it has received the input from the field worker to start saving or transmitting the captured image data. When it receives the input from the field worker to start saving or transmitting the captured image data, the control unit 12 starts storing the captured image data in the memory unit 181 or transmitting it to the information processing device 20.

[0084] 7B shows a state in which the wearable terminal 10 carried or worn by a field worker approaches a second work area where field work is performed on the outdoor unit 1002. In the state of FIG. 7B, the wearable terminal 10 has not yet started storing the captured image data in the storage unit 181 or transmitting the captured image data to the information processing device 20 because the field worker has not yet input an operation to start saving or transmitting the captured image data.

[0085] For example, in the state of Fig. 7C , when an input of an operation to start saving or transmitting captured image data by a field worker is received, the control unit 12 of the wearable device 10 performs the process of step S14. In step S14, the control unit 12 records the image capturing position or image capturing direction at the time of starting saving or transmitting the captured image data in the storage unit 181 as a reference. For example, the control unit 12 records the image capturing position or image capturing direction in the storage unit 181 as a reference, based on the state of Fig. 7C .

[0086] In step S16, the control unit 12 of the wearable terminal 10 predicts the current shooting position or shooting direction based on the shooting position or shooting direction at the start of saving or transmitting the shooting data recorded in the storage unit 181 in step S14. The shooting position or shooting direction is predicted using the angular velocity detected by the gyro sensor 185 and the acceleration detected by the acceleration sensor 186.

[0087] In step S18, the control unit 12 of the wearable terminal 10 compares the reference shooting position or shooting direction at the start of saving or transmitting the captured image data recorded in the storage unit 181 in step S14 with the current shooting position or shooting direction predicted in step S16, and determines a deviation. The control unit 12 determines a deviation from the reference shooting position or shooting direction at the start of saving or transmitting the captured image data recorded in the storage unit 181 in step S14.

[0088] In step S20, the control unit 12 of the wearable device 10 determines whether the deviation determined in step S18 is equal to or greater than a predetermined value. The control unit 12 repeats the processes of steps S16 to S20 until it determines that the deviation determined in step S18 is equal to or greater than a predetermined value.

[0089] 7D shows an example in which the on-site worker turns sideways from the state shown in FIG. 7C, but the deviation determined in step S18 is not greater than the predetermined value. In FIG. 7D, since the deviation determined in step S18 is not greater than the predetermined value, it is determined that on-site work is continuing in the second work area. Therefore, the control unit 12 continues storing the captured image data in the storage unit 181 or transmitting the captured image data to the information processing device 20.

[0090] Furthermore, if it is determined in step S18 that the deviation is equal to or greater than a predetermined value, the control unit 12 performs processing in step S22. In step S22, the control unit 12 ends the storage of the photographed data or ends the transmission of the photographed data. In step S22, the control unit 12 may end photographing.

[0091] 7E shows an example in which the deviation determined in step S18 is determined to be equal to or greater than a predetermined value because the on-site worker has moved away from the outdoor unit 1002, facing a direction significantly different from the direction of the outdoor unit 1002, from the state shown in FIG. 7C. In FIG. 7E, the deviation determined in step S18 is equal to or greater than a predetermined value, and therefore it is determined that the on-site worker has moved away from the second work area. Therefore, the control unit 12 terminates storage of the captured data in the storage unit 181 or transmission of the captured data to the information processing device 20.

[0092] 7E is an example in which step S18 determines that the deviation is greater than or equal to a predetermined value when the field worker is facing a direction that deviates from the direction of the outdoor unit 1002 by a predetermined value or more and is also farther away from the outdoor unit 1002 by a predetermined value or more. Determining the deviation by taking into account both the shooting position and shooting direction at the start of saving or transmitting the captured data allows for more accurate stopping of shooting, terminating saving of the captured data, or terminating transmission of the captured data than by taking into account either the shooting position or the shooting direction alone. Because the deviation can be accurately stopped, terminating saving of the captured data, or terminating transmission of the captured data, it is possible to reduce battery consumption in the wearable device 10 that is carried or worn by the field worker, captures the field worker's work, and saves or transmits the captured data to the information processing device 20.

[0093] For example, there are cases where a field worker working near the outdoor unit 1002, which is the target of the work, is talking to a customer with his back to the outdoor unit 1002, which is difficult to determine when the deviation is considered only in consideration of the shooting position. In such cases, by considering both the shooting position and the shooting direction, it is possible to treat a case where the shooting direction is significantly deviated as not being photographed, and it is possible to accurately stop shooting, end saving of the captured data, or end transmission of the captured data.

[0094] For example, there are cases where a site worker who has been disassembling the outdoor unit 1002, which is the target of the work, to replace a part turns in a direction other than the outdoor unit 1002 in order to place the disassembled part in another location, which is difficult when determining the deviation by considering only the shooting direction. In such cases, by considering both the shooting position and the shooting direction, it is possible to treat the object as being photographed if it is not far away from the shooting position, and it is possible to continue saving the photographed data or transmitting the photographed data with high accuracy.

[0095] For example, there are cases where a worker disassembles the outdoor unit 1002, which is the target of the work, to replace parts and turns his / her head in a direction other than the outdoor unit 1002 to take out tools, which is difficult to determine when only the shooting direction is taken into consideration. In such cases, by taking into consideration both the shooting position and the shooting direction, it is possible to treat the object as being photographed if it is not far from the shooting position, and it is possible to continue saving the photographed data or transmitting the photographed data with high accuracy.

[0096] The control unit 12 may determine in step S18 that the deviation is greater than or equal to a predetermined value when the on-site worker is facing in a direction that differs from the direction of the outdoor unit 1002 by a predetermined value or more, or when the on-site worker is away from the outdoor unit 1002 by a predetermined value or more.

[0097] The photographing position or photographing direction recorded in step S14 is used to determine whether or not to resume storing or transmitting the photographed data.

[0098] In step S26, the control unit 12 of the wearable terminal 10 controls the notification unit 184 to notify the field worker by sound, light, vibration, or the like that storage of the captured image data in the memory unit 181 or transmission to the information processing device 20 has been completed, and the process proceeds to step S28. Furthermore, if the control unit 12 of the wearable terminal 10 determines in step S12 that it has not received an input from the field worker to start saving or transmitting the captured image data, the process proceeds to step S24. In step S24, the control unit 12 of the wearable terminal 10 determines whether it has received an input from the field worker to stop capturing image data. If the control unit 12 receives an input from the field worker to stop capturing image data, the process ends the processing of the flowchart in FIG. 6. If the control unit 12 does not receive an input from the field worker to stop capturing image data, the process proceeds to step S28.

[0099] In step S28, the control unit 12 of the wearable terminal 10 predicts the current shooting position using the angular velocity detected by the gyro sensor 185 and the acceleration detected by the acceleration sensor 186. If the predicted current shooting position is within a predetermined range from the shooting position recorded in the storage unit 181 in step S14, the control unit 12 proceeds to step S30, and resumes storing the shooting data in the storage unit 181 or transmitting the shooting data to the information processing device 20, and then returns to the processing of step S16.

[0100] A shooting position where an input from a field worker to start saving or transmitting captured data has been received is likely to be a work area where the field worker wants to keep a first-person perspective video captured by the wearable device 10. Therefore, the control unit 12 resumes saving or transmitting the captured data in step S30 when the current shooting position of the wearable device 10 approaches within a predetermined range from a shooting position where an input from a field worker to start saving or transmitting captured data has been received. In step S28, if the predicted current shooting position is not within the predetermined range from the shooting position recorded in the storage unit 181 in step S14, the control unit 12 returns to the processing of step S12.

[0101] According to the processing of the flowchart in Figure 6, if a field worker performs an operation to start saving or transmitting the first captured data in a work area where he or she wants to keep the captured data captured by the wearable terminal 10, the saving or transmission of the second and subsequent captured data in that work area can be automatically resumed.

[0102] For example, in on-site work related to an air conditioner as shown in Figure 5, a worker moves between a first work area where work on the indoor unit 1000 is performed and a second work area where work on the outdoor unit 1002 is performed. Therefore, by using the wearable terminal 10 according to this embodiment, once an operation to start saving or transmitting captured data is performed in the first work area and the second work area, the saving or transmitting of the captured data can be automatically stopped when the worker moves out of the first work area and the second work area. Furthermore, by using the wearable terminal 10 according to this embodiment, once an operation to start saving or transmitting captured data is performed in the first work area and the second work area, the saving or transmitting of the captured data can be automatically resumed when the worker approaches the first work area and the second work area.

[0103] The wearable terminal 10 according to this embodiment can reduce battery consumption by automatically terminating the saving or transmission of captured image data upon moving out of the first working area and the second working area. Furthermore, the wearable terminal 10 according to this embodiment can reduce the storage capacity and communication volume of captured image data. As a result, the wearable terminal 10 according to this embodiment can reduce communication costs. Furthermore, the wearable terminal 10 according to this embodiment can extend the storage life.

[0104] Furthermore, the wearable terminal 10 according to this embodiment can prevent the storage of photographic data of the area visible from the path 1020 along which the field worker moves, which is preferable from the viewpoint of privacy.

[0105] Furthermore, according to the wearable terminal 10 of this embodiment, by suppressing the storage of photographic data within the range visible from the movement path 1020 of the on-site worker, the amount of photographic data stored in the wearable terminal 10 or the information processing device 20 is reduced, thereby reducing the workload of the analysis worker.

[0106] The flowchart in FIG. 6 shows an example in which the timing for accepting an input from the field worker to start shooting is different from the timing for accepting an input from the field worker to start saving or transmitting the shot data.

[0107] The timing at which the wearable device 10 receives an input from the field worker to start shooting and the timing at which the wearable device 10 receives an input from the field worker to start saving or transmitting the shot data may be the same. For example, the wearable device 10 may start storing the shot data in the storage unit 181 or transmitting the shot data to the information processing device 20 by receiving an input from the field worker to start shooting.

[0108] Fig. 8 is a flowchart of an example of the shooting control process according to this embodiment. Note that the process of the flowchart in Fig. 8 is similar to the flowchart in Fig. 6 except for some parts, and therefore the description will be omitted where appropriate.

[0109] In step S50, the control unit 12 of the wearable device 10 carried or worn by the field worker determines whether or not it has received an operation input from the field worker to start capturing images. The operation input from the field worker to start capturing images may be an operation input to the operation unit 150, voice recognition using sound signals acquired by the sound collection units 141 to 145, or detection of a specific gesture by the sensor unit 170. When the control unit 12 receives an operation input from the field worker to start capturing images, it starts storing the captured image data in the memory unit 181 or transmitting the captured image data to the information processing device 20.

[0110] In step S52, the control unit 12 records the shooting position or shooting direction at the start of shooting as a reference in the storage unit 181. In step S54, the control unit 12 of the wearable terminal 10 predicts the current shooting position or shooting direction based on the shooting position or shooting direction at the start of shooting recorded in the storage unit 181 in step S52.

[0111] In step S56, the control unit 12 of the wearable terminal 10 compares the reference shooting position or shooting direction at the start of shooting recorded in the memory unit 181 in step S52 with the current shooting position or shooting direction predicted in step S54, and determines the deviation.

[0112] In step S58, the control unit 12 of the wearable device 10 determines whether the deviation determined in step S56 is equal to or greater than a predetermined value. The control unit 12 repeats the processes of steps S54 to S58 until it determines that the degree of deviation determined in step S58 is equal to or greater than a predetermined value.

[0113] If the control unit 12 determines in step S58 that the deviation is equal to or greater than a predetermined value, the control unit 12 proceeds to step S60. In step S60, the control unit 12 stops capturing images. When capturing images is stopped, the control unit 12 stops saving the captured image data or stops transmitting the captured image data.

[0114] The photographing position or photographing direction recorded in step S52 is used to determine whether or not to resume photographing.

[0115] In step S64, the control unit 12 of the wearable terminal 10 controls the notification unit 184 to notify the field worker that image capture has ended by sound, light, vibration, or the like, and proceeds to step S66. Furthermore, if the control unit 12 of the wearable terminal 10 determines in step S50 that it has not received an operation input from the field worker to start image capture, it proceeds to step S62. In step S62, the control unit 12 of the wearable terminal 10 determines whether it has received an operation input from the field worker to stop image capture. If the control unit 12 receives an operation input from the field worker to stop image capture, it ends the processing of the flowchart in FIG. 8. If the control unit 12 does not receive an operation input from the field worker to stop image capture, it proceeds to step S66.

[0116] In step S66, the control unit 12 of the wearable terminal 10 predicts the current shooting position. If the predicted current shooting position is within a predetermined range from the shooting position recorded in the storage unit 181 in step S52, the control unit 12 proceeds to step S68, restarts shooting, and then returns to the processing of step S54.

[0117] The image capturing position where the field worker has previously input an operation to start image capturing is likely to be a work area where the field worker wants to record a first-person perspective video captured by the wearable device 10. Therefore, the control unit 12 resumes image capturing in step S68 when the current image capturing position of the wearable device 10 approaches within a predetermined range from the image capturing position where the field worker has previously input an operation to start image capturing. Also, in step S66, if the predicted current image capturing position is not within the predetermined range from the image capturing position recorded in the storage unit 181 in step S52, the control unit 12 returns to the processing of step S50.

[0118] According to the processing of the flowchart in Figure 8, a field worker can automatically resume taking second and subsequent photographs in the work area by performing an operation to start the first photograph in the work area where he or she wants to keep the photographed data taken by the wearable terminal 10.

[0119] 6 or 8, an existing image recognition technology may be used to predict the shooting position or shooting direction. For example, the wearable terminal 10 can predict the shooting position or shooting direction of the wearable terminal 10 by recognizing the indoor unit 1000, the outdoor unit 1002, etc. that appear in the shooting data while the shooting data is being saved or transmitted. Also, for example, in the flowchart of FIG. 6, the wearable terminal 10 may recognize the indoor unit 1000, the outdoor unit 1002, etc. that appear in the shooting data when saving or transmitting the shooting data is resumed, and predict the shooting position or shooting direction of the wearable terminal 10.

[0120] The prediction of the shooting position or direction using image recognition technology can be used to start saving the photographed data, end saving the photographed data, start transmitting the photographed data, or end transmitting the photographed data, if shooting continues after saving or transmitting the photographed data has finished. Also, the prediction of the shooting position or direction using image recognition technology can be used to stop shooting, end saving the photographed data, or end transmitting the photographed data, if shooting does not continue after saving or transmitting the photographed data has finished.

[0121] The prediction of the shooting position or shooting direction using the image recognition technology may be used in combination with the prediction of the shooting position or shooting direction using the angular velocity detected by the gyro sensor 185 and the acceleration detected by the acceleration sensor 186. Furthermore, the prediction of the shooting position or shooting direction using the image recognition technology may be used instead of the prediction of the shooting position or shooting direction using the angular velocity detected by the gyro sensor 185 and the acceleration detected by the acceleration sensor 186.

[0122] In addition, in this embodiment, as shown in Figure 5, an example has been described in which there are two work areas where the wearable terminal 10 wants to record first-person perspective video of the on-site worker, but this is not limited to two areas and may be one area or three or more areas.

[0123] As described above, according to the information processing system 1 of this embodiment, it is possible to reduce battery consumption of the wearable terminal 10 that is carried or worn by a field worker to photograph the field work of the field worker, and which stores or transmits the photographed data to the information processing device 20.

[0124] [Function] This embodiment is a wearable terminal 10 that has a control unit 12 and is carried by a field worker to take pictures. The control unit 12 determines the deviation from the shooting position or shooting direction when saving or transmission of the captured data begins, and based on the deviation, stops shooting, ends saving of the captured data, or ends transmission of the captured data.

[0125] The control unit 12 determines a deviation from the shooting position or shooting direction at the time when the shooting data starts to be stored in the storage unit 181 or when the transmission to the information processing device 20 starts. The deviation represents a deviation between the shooting position or shooting direction at the time when the shooting data starts to be stored in the storage unit 181 or when the transmission to the information processing device 20 starts and the current shooting position or shooting direction.

[0126] If the deviation is equal to or greater than a predetermined value, the current shooting position or shooting direction is away from the shooting position or shooting direction at the time when storage of the shooting data in the storage unit 181 started or transmission to the information processing device 20 started. Therefore, if the deviation is equal to or greater than a predetermined value, the control unit 12 stops shooting, ends storage of the shooting data, or ends transmission of the shooting data.

[0127] In this way, according to this embodiment, it is possible to reduce battery consumption of the wearable terminal 10, which is carried or worn by a field worker to photograph the field work of the field worker, and which stores or transmits the photographed data to the information processing device 20.

[0128] In addition, in this embodiment, the wearable terminal 10 captures video from a first-person perspective while being worn by a field worker.

[0129] According to this embodiment, the wearable terminal 10 can be used by a field worker to capture first-person perspective video while being worn by the field worker.

[0130] In addition, in this embodiment, the control unit 12 determines the deviation from the photographing position and photographing direction at the time when the storage or transmission of the photographed data starts.

[0131] The control unit 12 determines a deviation from the shooting position and shooting direction at the time when the shooting data starts to be stored in the storage unit 181 or when the transmission to the information processing device 20 starts. The deviation represents a deviation between the shooting position and shooting direction at the time when the shooting data starts to be stored in the storage unit 181 or when the transmission to the information processing device 20 starts and the current shooting position and shooting direction.

[0132] If the deviation is equal to or greater than a predetermined value, the current shooting position and shooting direction are away from the shooting position and shooting direction at the start of storage of the shooting data in the storage unit 181 or the start of transmission to the information processing device 20. Therefore, if the deviation is equal to or greater than a predetermined value, the control unit 12 stops shooting, ends saving of the shooting data, or ends transmission of the shooting data.

[0133] In this way, according to this embodiment, it is possible to reduce battery consumption of the wearable terminal 10, which is carried or worn by a field worker to photograph the field work of the field worker, and which stores or transmits the photographed data to the information processing device 20.

[0134] In addition, in this embodiment, the control unit 12 records the shooting position when the saving or transmission of the shooting data starts in the memory unit 181, and after stopping shooting, ending the saving of the shooting data, or ending the transmission of the shooting data, if it approaches within a predetermined range from the shooting position, it resumes shooting, restarts the saving of the shooting data, or restarts the transmission of the shooting data.

[0135] According to this embodiment, by recording the shooting position when saving or transmission of the shooting data starts, when the user approaches within a specified range from the recorded shooting position, shooting can be resumed, saving of the shooting data can be resumed, or transmission of the shooting data can be resumed.

[0136] In this embodiment, the control unit 12 records in the storage unit 181 a plurality of shooting positions at the time of starting to save or start to transmit the shooting data.

[0137] According to this embodiment, by recording multiple shooting locations at the time when saving or transmission of the shooting data begins, when the device approaches within a specified range of any of the shooting locations included in the multiple recorded shooting locations, saving of the shooting data or transmission of the shooting data can be resumed.

[0138] In this embodiment, the control unit 12 starts saving or transmitting the captured image data in accordance with an operation by a site worker.

[0139] According to this embodiment, the saving of photographed data or the transmission of photographed data can be started in accordance with the operation of the field worker.

[0140] In addition, in this embodiment, the control unit 12 controls the notification unit 184 to notify the on-site worker of the start of shooting, the end of shooting, the start of saving the shooting data, the end of saving the shooting data, the start of transmitting the shooting data, or the end of transmitting the shooting data.

[0141] According to this embodiment, the wearable terminal 10 can notify the field worker of the start of shooting, the end of shooting, the start of saving the captured data, the end of saving the captured data, the start of transmitting the captured data, or the end of transmitting the captured data.

[0142] In addition, in this embodiment, the control unit 12 continues shooting and terminates saving of the shooting data or terminates transmission of the shooting data based on the deviation.

[0143] According to this embodiment, while continuing to capture images, it is possible to stop saving or transmitting the captured image data based on the deviation. For example, since the wearable device 10 continues capturing images even after stopping saving or transmitting the captured image data, it is possible to use prediction of the capturing position or direction using image recognition technology to start saving or transmitting the captured image data.

[0144] This embodiment is a photography control method executed by a wearable terminal 10 that has a control unit 12 and is carried by a field worker to take photographs. The control unit 12 determines the deviation from the photography position or photography direction at the time when saving or transmission of the photographed data begins, and based on the deviation, stops photography, ends saving of the photographed data, or ends transmission of the photographed data.

[0145] The control unit 12 determines a deviation from the shooting position or shooting direction at the time when the shooting data starts to be stored in the storage unit 181 or when the transmission to the information processing device 20 starts. The deviation represents a deviation between the shooting position or shooting direction at the time when the shooting data starts to be stored in the storage unit 181 or when the transmission to the information processing device 20 starts and the current shooting position or shooting direction.

[0146] If the deviation is equal to or greater than a predetermined value, the current shooting position or shooting direction is away from the shooting position or shooting direction at the time when storage of the shooting data in the storage unit 181 started or transmission to the information processing device 20 started. Therefore, if the deviation is equal to or greater than a predetermined value, the control unit 12 stops shooting, ends storage of the shooting data, or ends transmission of the shooting data.

[0147] In this way, according to this embodiment, it is possible to reduce battery consumption of the wearable terminal 10, which is carried or worn by a field worker to photograph the field work of the field worker, and which stores or transmits the photographed data to the information processing device 20.

[0148] Although the present embodiment has been described above, it will be understood that various modifications in form and details are possible without departing from the spirit and scope of the claims. While the present invention has been described above based on examples, the present invention is not limited to the above examples and various modifications are possible within the scope of the claims.
