Embodiments of the present disclosure are described in detail below with reference to the drawings. In the drawings, the same or corresponding elements are labeled with the same reference numerals. Duplicate explanations are omitted as necessary for clarity of explanation.

The configuration of a recording system 1000 according to this embodiment will be described with reference to FIG. FIG. 1 is a block diagram showing the configuration of a recording system 1000 according to this embodiment. The recording system 1000 includes an in-vehicle device 100 mounted on a vehicle 50 , a sensor section 200 , a storage section 300 , a lock control section 350 , an imaging section 400 , and a recipient terminal 80 communicating with the in-vehicle device 100 .

The recording system 1000 is an example of a storage device that captures an image of the vicinity of a storage unit that stores a delivery when the recipient of the delivery receives the delivery without facing the delivery person, and records the captured image. be. A delivery can be anything, such as a package, parcel, letter, or groceries, for example. In addition, the sender, deliverer, and recipient of the delivered item may each be an individual or a corporation.
In this embodiment, a case where a delivery person who is an employee of a delivery company delivers a package to an individual recipient will be described as an example.

Each configuration of the recording system 1000 will be described.
The recipient terminal 80 is a terminal used by the recipient of the parcel. The recipient terminal 80 is, for example, an information terminal such as a PC (Personal Computer), a mobile phone terminal, a smart phone, or a tablet terminal. The recipient terminal 80 wirelessly communicates with the in-vehicle device 100 . For wireless communication, communication methods such as Bluetooth (registered trademark) and Wi-Fi (registered trademark) can be used. Also, the recipient terminal 80 may communicate with the in-vehicle device 100 using a communication line such as the Internet.

The recipient uses the recipient terminal 80 to change the method of receiving the parcel. Also, the recipient uses the recipient terminal 80 to register the slip number of the package in the in-vehicle device 100 in advance. Registration of the slip number will be described later.

Next, the in-vehicle device 100 will be described.
The in-vehicle device 100 includes a registration unit 110 , an authentication unit 120 , a storage detection unit 130 , an imaging control unit 140 , a communication unit 150 and a recording unit 190 .

The registration unit 110 preliminarily registers identification information for identifying a package or a delivery person in the in-vehicle device 100 . The identification information for identifying the package is, for example, the slip number of the slip attached to the package. Further, the identification information for identifying the delivery person is, for example, the biometric information of the delivery person, the employee number, or the like.

The slip number is a number used for management from shipment of the package to completion of delivery. The slip number may include, for example, multiple numbers and letters. The slip number may be represented by a one-dimensional code such as a bar code, or may be represented by a two-dimensional code such as a QR code (registered trademark).

The slip number is previously notified to the recipient terminal 80 by e-mail or the like from the sender or the delivery person of the parcel. Alternatively, the payee may obtain the voucher number from a copy of the voucher. The recipient or the delivery person can check the delivery status of the parcel at a desired timing based on the slip number via a tracking web page or the like.

When the recipient wishes to receive the package using the recording system 1000 , the recipient uses the recipient terminal 80 to perform a registration process of pre-registering the slip number in the in-vehicle device 100 . A predetermined application or the like may be used for the registration process. The recipient inputs the slip number from the input unit (not shown) of the recipient terminal 80 and transmits the slip number to the in-vehicle device 100 . The registration unit 110 receives the transmitted slip number and registers it in the recording unit 190 as slip number information 191 . This completes the slip number registration process. The recipient may register the storage location of the parcel and the desired delivery date and time together with the slip number.

In addition to directly inputting the slip number and sending it as described above, the recipient can display the slip number, barcode, etc. on the display screen of the recipient terminal 80 and cause the image capturing unit 400 to read the displayed content. You can register the slip number by the following method. Alternatively, the photographing unit 400 may read a bar code or the like written on a copy of the slip. Since the recipient terminal 80 and the in-vehicle device 100 can communicate with each other via the Internet without communicating with an external server, the slip number can be registered safely with a simpler configuration.

The registration unit 110 may register biometric information, an employee number, or the like of a delivery person as identification information for identifying the delivery person. Biometric information is information that indicates physical characteristics unique to an individual. Biometric information is, for example, information that indicates features such as the delivery person's face, fingerprints, or iris. Not limited to these, other biometric information may be used. Further, feature information indicating these features may be used as biometric information.
The employee number is a number for identifying the delivery person in the company to which the delivery person belongs. Any information that identifies the delivery person may be used, not limited to the employee number.

The registration unit 110 receives biometric information and employee number information of the delivery person from, for example, an information terminal used by the corporation to which the delivery person belongs, and registers them in the recording unit 190 as delivery person information 192 . For example, the registration unit 110 registers facial feature information indicating facial features of the delivery person as the delivery person information 192 . Alternatively, the registration unit 110 registers the employee number of the delivery person as the delivery person information 192 . This completes the process of registering the biometric information of the delivery person and the employee number.

In the following description, the slip number information 191 or the delivery person information 192 registered in advance in this manner may be referred to as "registered information".

The authentication unit 120 authenticates a package to be delivered or a delivery person who delivers the package. The authentication unit 120 authenticates the package or the delivery person by comparing the identification information for identifying the package or the delivery person acquired from the captured image of the imaging unit 400 with pre-registered registration information.

When a package is authenticated using a slip number, the authentication unit 120 acquires the slip number included in the captured image from the image captured by the imaging unit 400 by image recognition. The authentication unit 120 refers to the slip number information 191 and determines whether or not the acquired slip number matches the slip number registered in the slip number information 191 . The authentication unit 120 determines that the package authentication has succeeded when it is determined that the acquired slip number and the registered slip number match, and otherwise determines that the package authentication has failed.

Note that the authentication unit 120 may acquire the slip number by any method other than image recognition. For example, the delivery person terminal used by the delivery person may transmit the slip number to the in-vehicle device 100 . The delivery person terminal is, like the recipient terminal 80, a PC, a mobile phone terminal, or the like.

Also, when biometric authentication of the delivery person is performed, the authentication unit 120 acquires biometric information of the delivery person included in the captured image from the captured image acquired by the imaging unit 400 . Here, it is assumed that the face image of the delivery person is photographed and face authentication is performed. The authentication unit 120 acquires the face image of the delivery person from the acquired photographed image by image recognition, and extracts facial feature information of the delivery person from the face image. The authentication unit 120 refers to the courier information 192 and determines whether or not the extracted facial feature information matches the registered facial feature information in the courier information 192 . Note that, when the extracted facial feature information and the registered facial feature information match each other by a predetermined value or more, the authentication unit 120 may determine that the two match each other. An authentication part 120 determines that the authentication of the delivery person is successful when it is determined that the extracted facial feature information and the registered contents match each other, and determines that the authentication of the delivery person is unsuccessful otherwise.

The authentication unit 120 may recognize the delivery person's employee ID card from the photographed image, for example, and authenticate the delivery person from the employee number.
If the parcel or delivery person is successfully authenticated, the authentication unit 120 outputs a request to unlock the storage unit 300 to the lock control unit 350 of the vehicle 50 .

The authentication unit 120 may manage the slip numbers so that re-authentication cannot be performed using the slip numbers that have been successfully authenticated. For example, the authentication unit 120 deletes the slip number information 191 corresponding to the authenticated slip number. As a result, it becomes impossible to unlock the storage section 300 using the same slip number after the delivery is completed, so that the crime prevention effect can be further enhanced.

The storage detection unit 130 detects that a package has been stored in the storage unit 300 . For example, the storage detection unit 130 detects that a package is stored in the storage unit 300 by acquiring the weight of the object stored in the storage unit 300 from the weight sensor 230 .

The storage detection unit 130 may detect that the luggage has been stored in response to the storage unit 300 being locked. Further, the storage detection unit 130 may detect that the luggage has been stored when the locked storage unit 300 is unlocked by a predetermined procedure and then locked. A predetermined procedure is, for example, a parcel or carrier authentication procedure, as described above. The storage detection unit 130 unlocks the storage unit 300 by successfully authenticating the package or the delivery person in the authentication unit 120, and stores the package in the storage unit 300 when the storage unit 300 is subsequently locked. detect that

Alternatively, the receipt detection unit 130 may detect receipt of the package upon receiving a notification that the package has been delivered from the delivery person's terminal. The delivery person may make the notification by communicating with the in-vehicle device 100 via Bluetooth (registered trademark) or the like immediately after receiving the package, or may make the notification at an arbitrary timing via the Internet or the like.

Further, the storage detection unit 130 may compare the number of packages stored and the number of packages registered in advance, and notify the receiver terminal 80 of the comparison result. For example, the storage detection unit 130 counts the number of parcels stored in the storage unit 300, and if the number is different from the number of pre-registered parcels, notifies the recipient terminal 80 to that effect. The stored number is, for example, the number of slip numbers read by the imaging unit 400 and successfully authenticated.

Alternatively, the storage detection unit 130 may photograph the packages in the storage unit 300 with the imaging unit 400 and use the number of packages recognized from the captured image as the storage number. Not limited to these, the storage detection unit 130 may acquire the weight of the luggage with the weight sensor 230 and count the number of storage. In this case, the approximate weight of the packages may be registered in advance, and the number of stored packages may be obtained by comparing the weight of the packages stored with the approximate weight.

The imaging control section 140 controls the imaging section 400 according to the detection result of the storage detection section 130 . The photographing control unit 140 controls the photographing unit 400 so that when it is detected that the luggage is stored in the storage unit 300, the photographing is performed under different photographing conditions from when the storage of the luggage is not detected. The shooting conditions may include conditions related to shooting in the vicinity of the storage unit 300 . The shooting conditions may include, for example, the timing to start or stop shooting, the shooting image quality, the type of recording start trigger, the sensitivity of the recording start trigger, and the like. The recording start trigger is a trigger for starting recording of the captured image in the recording unit 190 .

The photographing control unit 140 controls the photographing unit 400 so that the ability to monitor the vicinity of the storage unit 300 can be enhanced after the storage of luggage is detected than before the storage of luggage is detected. . In this embodiment, the in-vehicle device 100 is capable of setting two monitoring modes for monitoring the vehicle 50 . The in-vehicle device 100 performs monitoring in the "normal monitoring mode" before detection of storage of the luggage, and switches the monitoring mode to the "load monitoring mode" after detection of storage of the luggage. The parcel monitoring mode is a monitoring mode capable of enhancing the ability to monitor the vicinity of the storage unit 300 compared to the normal monitoring mode.

First, the normal monitoring mode will be explained. The normal monitoring mode is, for example, a monitoring mode that is set when the vehicle 50 is parked regardless of whether or not luggage is stored. When the in-vehicle device 100 detects that the engine of the vehicle 50 is stopped by an ignition switch (not shown), for example, it starts monitoring in the normal monitoring mode. The normal monitoring mode is, for example, constant recording in which the frame rate is intermittent recording such as one frame per second, or recording started by a recording start trigger, which will be described later.

When a change in the vehicle condition is detected, the photographing control unit 140 uses this as a recording start trigger to record, in the recording unit 190, captured images for a predetermined time (for example, 5 minutes) before and after the change in the vehicle condition is detected. A change in vehicle condition indicates a change in condition that has occurred in the vehicle 50 . Changes in vehicle conditions may include, for example, an impact on the vehicle 50, vibrations in the vehicle 50, sounds generated in the vehicle 50 or in the vicinity of the vehicle 50, people approaching the vehicle 50, and the like. Changes in vehicle conditions may include not only changes related to the main body of vehicle 50 but also changes related to the surroundings of vehicle 50 .

The imaging control unit 140 acquires measured values from the sensor unit 200 and detects changes in vehicle conditions by comparing the measured values with a predetermined threshold value. For example, the imaging control unit 140 detects that the vehicle 50 has received an impact when the measured value of the acceleration sensor 240 is equal to or greater than a predetermined value. The imaging control unit 140 starts recording the captured image using the detection of the impact as a recording start trigger. The photographing control unit 140 may detect changes in the vehicle state using not only the sensor unit 200 but also the photographed image acquired by the photographing unit 400 .

In the normal monitoring mode, the photographing control unit 140 constantly photographs the vicinity of the vehicle 50 before the impact is detected, and temporarily records the photographed image. When detecting a change in the vehicle condition (for example, an impact), the photographing control unit 140 stores photographed images of a predetermined time (for example, 5 minutes) before and after the detection as photographed images 193 in the recording unit 190 . Thereby, the photographing control unit 140 can record the photographed image from the timing before the change of the vehicle condition occurs.

If a state in which no change in the vehicle condition is detected continues for a predetermined period of time, the imaging control unit 140 may secure a storage area by appropriately deleting captured images that have been temporarily recorded. If the photographed image before the change in the vehicle condition is detected is not recorded, the photographing control unit 140 starts photographing and recording the photographed image in the recording unit 190 at the timing when the change in the vehicle condition is detected. You may do so.

Next, the baggage monitoring mode will be explained. The baggage monitoring mode is a monitoring mode that is started after the storage detection unit 130 detects the storage of the baggage. In the baggage monitoring mode, the imaging control unit 140 controls the imaging unit 400 so as to perform imaging under imaging conditions different from those in the normal monitoring mode. The control of the imaging unit 400 can include, for example, control of timing to start or stop imaging, control of imaging image quality, control of recording start trigger type or sensitivity, and the like.

FIG. 2 is a diagram showing an example of photographing conditions in the normal monitoring mode and the parcel monitoring mode.
The photographing control unit 140 controls the photographing unit 400 so that the photographed image quality becomes higher when the normal surveillance mode is shifted to the parcel surveillance mode. Also, the imaging control unit 140 controls the imaging unit 400 so as to increase the sensitivity of the recording start trigger.

As shown in FIG. 2, for example, the imaging control unit 140 controls the imaging unit 400 so that the bit rate in the parcel monitoring mode is higher than that in the normal monitoring mode. Also, the imaging control unit 140 may control the imaging unit 400 so that the frame rate in the parcel monitoring mode is higher than that in the normal monitoring mode. Further, the imaging control unit 140 may control the imaging unit 400 so that the resolution in the parcel monitoring mode is higher than that in the normal monitoring mode. The imaging control unit 140 may control the imaging unit 400 by combining two or more of these imaging conditions. As a result, the image capturing unit 400 can capture a higher quality image.

The imaging control unit 140 may obtain the position of the package from the captured image using a technique such as image recognition, and may control the imaging unit 400 to change the imaging conditions according to the position of the package. For example, the imaging control unit 140 controls the imaging unit 400 to increase the frame rate only for the angle of view of the window near the position of the package. As a result, the storage area can be efficiently secured while enhancing the crime prevention function.

Further, as shown in FIG. 2, the imaging control section 140 may control the imaging section 400 so as to increase the sensitivity of the recording start trigger. For example, the imaging control unit 140 controls the imaging unit 400 so that the sensor sensitivity and sensor type are different for each monitoring mode with respect to the recording start trigger. For example, the imaging control unit 140 sets the sensitivity with which the sensor unit 200 detects a change in the vehicle condition of the vehicle 50 to be higher in the baggage monitoring mode than in the normal monitoring mode. For example, it is assumed that a predetermined threshold is set for the acceleration detected by the acceleration sensor 240 in order to detect an impact on the vehicle 50 . In this case, a lower threshold value is set in the parcel monitoring mode than in the normal monitoring mode. As a result, the imaging control unit 140 can detect an impact with higher sensitivity in the parcel monitoring mode than in the normal monitoring mode. Therefore, the shooting control unit 140 can detect the occurrence of a smaller impact and start recording a shot image.

Moreover, the sound pressure sensor 250 or the human sensor 260 may be used to detect changes in the vehicle condition, instead of the acceleration sensor 240 described above. For example, when the sound pressure sensor 250 detects a sound having a predetermined sound pressure or more, the imaging control unit 140 detects the occurrence of an abnormal sound as a change in vehicle conditions. The abnormal sound is, for example, a sound generated when a person enters the vehicle 50, a sound of forcing a door lock, or a sound of breaking a windshield or a window glass. In this case, the photographing control unit 140 sets the threshold value for detecting abnormal sound generated by the sound pressure sensor 250 as a change in vehicle condition to be lower in the baggage monitoring mode than in the normal monitoring mode.
In addition, the photographing control unit 140 may detect a change in the vehicle condition when the human sensor 260 detects the approach of a person.

As shown in FIG. 2, the imaging control unit 140 may perform control according to the types of these sensors. For example, in the normal monitoring mode, only the acceleration sensor 240 is used to detect changes in the vehicle status, and in the cargo monitoring mode, both the acceleration sensor 240 and the human sensor 260 are used to detect changes in the vehicle status. In the baggage monitoring mode, the imaging control unit 140 performs control to start recording when either the acceleration sensor 240 or the human sensor 260 detects a change in vehicle conditions. By providing a plurality of recording start triggers in this way, it is possible to increase the sensitivity of the sensor that serves as the recording start trigger.

In this embodiment, the normal monitoring mode and the package monitoring mode are used to describe the control of the photographing control unit 140 after package storage, but the present invention is not limited to this. Before the luggage is stored, it may be in a state in which monitoring by the normal monitoring mode or the like is not performed. For example, the photographing control unit 140 may start the luggage monitoring mode from a state in which no monitoring is performed when storage of luggage is detected.

Further, the imaging control unit 140 may control the imaging unit 400 according to the content of the parcel. For example, the imaging control unit 140 may control the imaging unit 400 so that the higher the value of the parcel, the higher the imaging quality, or the higher the sensitivity of the recording start trigger.

Returning to FIG. 1, the description is continued.
The communication unit 150 connects the recipient terminal 80 and the in-vehicle device 100 by wireless communication. The communication unit 150 is a communication interface for performing communication according to wireless standards such as Bluetooth (registered trademark) and Wi-Fi (registered trademark). The communication unit 150 may be configured to be able to communicate with the recipient terminal 80 and the delivery person terminal via the Internet or the like.

The recording unit 190 stores the slip number information 191 and the delivery person information 192 described above. Also, the recording unit 190 records an image captured after the package is stored as a captured image 193 . The photographed image 193 may include information such as the photographing date and time. Also, the recording unit 190 may temporarily record an image constantly captured by the imaging unit 400 . These pieces of information recorded in the recording unit 190 may be appropriately deleted after a predetermined period of time has elapsed.

The sensor unit 200 includes a trunk opening/closing sensor 210 , a door opening/closing sensor 220 , a weight sensor 230 , an acceleration sensor 240 , a sound pressure sensor 250 and a motion sensor 260 .
Trunk opening/closing sensor 210 and door opening/closing sensor 220 detect opening/closing of doors corresponding to trunk 301 and seating space 302, respectively. Weight sensor 230 detects the weight of an object stored in storage unit 300 . Acceleration sensor 240 detects the acceleration of vehicle 50 .

The sound pressure sensor 250 detects sounds generated inside the vehicle 50 or near the vehicle 50 . Sound pressure sensor 250 is, for example, a microphone.
Human sensor 260 is a sensor that detects the approach of a person to vehicle 50 .
These are examples, and the sensor unit 200 may include other sensors.

The storage unit 300 is a space for storing delivered items. Here, a trunk 301 and a seating space 302 are shown as an example. Trunk 301 is an independent trunk. A seating space 302 is a space in which a passenger is seated. The storage unit 300 is not limited to this, and may be of any type as long as the storage unit 300 can store items to be delivered.

Also, in the present embodiment, an example in which the storage unit 300 is provided in the vehicle 50 has been described, but the present invention is not limited to this. A space other than the vehicle may be used as the storage unit 300 . Storage unit 300 may be, for example, a delivery box, a mailbox, a storeroom, or a house. In this case, the in-vehicle device 100 may be a recording device that is not mounted on the vehicle, and may be a device that captures and records the storage section 300 .

In this embodiment, the delivery person authenticates the parcel or the delivery person by means of a slip number, face authentication, or the like, and upon successful authentication, the lock control unit 350 unlocks the storage unit 300 . This allows the delivery person to store the package in the storage section 300 . When the delivery person locks the storage unit 300 after storing the package, the storage detection unit 130 detects the storage of the package. For these reasons, it is desirable that the storage unit 300 can be unlocked and locked.

The storage unit 300 may not require unlocking procedures by the delivery person. In this case, the storage detection unit 130 detects storage of luggage when the unlocked storage unit 300 is locked.

The lock control unit 350 controls locking and unlocking of the storage unit 300 . The lock control unit 350 receives an unlocking request from the authentication unit 120 and unlocks the storage unit 300 when the authentication unit 120 successfully authenticates the parcel or the delivery person. A lock control unit 350 locks and unlocks the doors corresponding to the trunk 301 and the seating space 302 . As a result, the doors of the locked trunk 301 and the seating space 302 are unlocked, so that the delivery person can store the parcel in these spaces in the vehicle 50 .

The photographing unit 400 is a photographing device that photographs the inside of the vehicle 50 and the surroundings of the vehicle 50 to obtain a photographed image. The captured image may be a still image or a moving image. The imaging unit 400 is, for example, a visible light camera or an infrared camera, and is provided inside or outside the vehicle 50 . The photographing unit 400 is provided at a position capable of photographing at least the vicinity of the storage unit 300 .

In this embodiment, the imaging unit 400 includes a front camera 410 , a vehicle interior camera 420 and a rear camera 430 . The front camera 410, the vehicle interior camera 420, and the rear camera 430 are provided at positions capable of photographing the front, interior, and rear of the vehicle 50, respectively. These are examples, and the number of cameras included in the imaging unit 400 is not limited to three.

The above is the description of each configuration of the recording system 1000 . The configuration of the recording system 1000 shown in FIG. 1 is merely an example. The recording system 1000 may be configured using a device or the like in which multiple configurations are integrated. For example, some or all of the functions of the in-vehicle device 100, the sensor unit 200, and the imaging unit 400 may be integrated into the same device. Further, for example, each functional unit of the in-vehicle device 100 may perform distributed processing using a plurality of devices.

Next, the flow of the luggage storage method according to the present embodiment will be described with reference to FIG. FIG. 3 is a diagram showing the flow of a delivery person 60 storing a package (delivery item) 70 in a trunk 301. As shown in FIG. Here, the delivery person 60 who is an employee of the delivery company completes the delivery by storing the package 70 in the trunk 301 of the vehicle 50 owned by the recipient. Although not shown in FIG. 3, the recipient uses the recipient terminal 80 to perform various operations. In the following description, each functional unit described with reference to FIG. 1 will be used as appropriate.

First, the recipient receives, via the recipient terminal 80, a notification that there is a package addressed to the recipient by e-mail or the like. The notification includes, for example, the sender, the name of the delivery person, the slip number, and the scheduled date and time of delivery. The slip number is identification information for identifying the parcel 70 . The slip number is written on the slip 75 attached to the package.

FIG. 3A is a diagram showing an example of the slip 75. As shown in FIG. In addition to the slip number, the slip 75 includes the recipient's name, address, contact information, designated delivery time, and the like. A delivery person 60 delivers the package 70 based on the address written on the slip 75 . Although a plurality of numbers are shown as an example of the slip number in FIG. 3A, the slip number may be represented by a bar code, a QR code (registered trademark), or the like.

The recipient operates the recipient terminal 80 and performs procedures to change the delivery method from the normal face-to-face receiving method to the receiving method by storing in the vehicle 50 . The recipient performs the change procedure via the web page for the procedure from the URL or the like described in the e-mail, for example. Hereinafter, the state in which the procedure is completed will be referred to as a "baggage waiting mode". After transitioning to the parcel waiting mode, the in-vehicle device 100 can accept input of a slip number from the recipient.

The recipient registers the slip number from the recipient terminal 80 to the in-vehicle device 100 via a predetermined application or the like. The recipient inputs the slip number to the recipient terminal 80 and transmits the input contents to the in-vehicle device 100 . The recipient may register the slip number by displaying the slip number, bar code, or the like on the display screen of the recipient terminal 80 and having the photographing unit 400 read the displayed content. Also, if a copy of the slip 75 is at hand, it may be used to cause the photographing unit 400 to read the slip number.

The registration unit 110 receives the slip number from the recipient terminal 80 and records it in the recording unit 190 as slip number information 191 . This completes the registration of the slip number in the in-vehicle device 100 . The recipient may register the desired delivery date and time, storage location, etc. together with the slip number. Here, it is assumed that the trunk 301 is designated as the storage location.

The recipient parks the vehicle 50 at a predetermined location. When the imaging control unit 140 detects that the engine of the vehicle 50 has stopped, the imaging control unit 140 starts monitoring in the normal monitoring mode. Accordingly, the vehicle 50 can be monitored even before the luggage 70 is stored.

FIG. 3(b) is a diagram showing how the delivery person 60 delivers the package 70. As shown in FIG. The delivery person 60 moves to the vicinity of the vehicle 50 in a delivery vehicle or the like according to the address written on the slip 75 and carries the parcel 70 to the vehicle 50 .

FIG. 3(c) is a diagram showing the appearance of the delivery man 60 photographed by the vehicle interior camera 420. As shown in FIG. When delivery man 60 puts his hand on trunk 301, acceleration sensor 240 detects the impact. When the impact is detected, the shooting control unit 140 controls the shooting unit 400 to start recording the shot image. The photographing control unit 140 records the photographed image from before the impact is detected as the photographed image 193 . It should be noted that a sensor other than the acceleration sensor 240 may be used to detect changes in vehicle conditions and start recording.

The delivery person 60 presents the slip 75 attached to the parcel 70 to the rear camera 430 or the like. The rear camera 430 photographs the slip 75, and the authentication unit 120 recognizes the slip number from the photographed image. The authentication unit 120 refers to the slip number information 191 and determines whether or not the photographed slip number has been registered. If the slip number has already been registered, the authentication unit 120 determines that the slip number has been successfully authenticated. Although the slip number is used here, the authentication unit 120 uses the face of the delivery person 60 and the image of the employee ID card captured by the rear camera 430 to perform authentication by face authentication, employee number, or the like. good too.

If the slip number is successfully authenticated, the lock controller 350 unlocks the trunk 301 . The delivery person 60 opens the trunk 301 and stores the package 70 . FIG. 3(d) is a diagram showing how the delivery person 60 stores the package 70. As shown in FIG. Although the vehicle interior camera 420 captures the image of the delivery person 60 here, the front camera 410 or the rear camera 430 may capture the image depending on the storage location.

The delivery person 60 closes the trunk 301 after storing the package 70 . Lock control unit 350 locks trunk 301 . When trunk 301 is locked, storage detector 130 detects that luggage 70 has been stored in trunk 301 . The photographing control unit 140 records the photographed image for a predetermined period of time after detecting the storage of the package 70 .

When there are multiple parcels 70, the delivery person 60 may open and close the trunk 301 multiple times. The delivery person 60 can unlock the trunk 301 again by presenting the slip number of the unpacked package. Further, in the case where one slip number is assigned to a plurality of parcels, it may be set so that the trunk 301 can be unlocked multiple times with one slip number.

When the storage of the package 70 is detected, the imaging control unit 140 switches the monitoring mode from the normal monitoring mode to the package monitoring mode. After this, the monitoring by the baggage monitoring mode continues. When a change in the vehicle condition is detected during the luggage surveillance mode, the imaging control section 140 controls the imaging section 400 based on the imaging conditions set in the luggage surveillance mode. The imaging unit 400 performs imaging under the control of the imaging control unit 140 . The recording unit 190 records the captured image captured in the package monitoring mode as the captured image 193 .

By doing so, it is possible to record a photographed image in the normal monitoring mode before the baggage 70 is stored, and to monitor the baggage in the baggage monitoring mode having a higher monitoring capability after the storage.

Next, processing executed by the recording system 1000 will be described with reference to FIGS. 4 and 5. FIG.
4 and 5 are sequence diagrams showing processing executed by the recording system 1000. FIG. FIG. 4 is a sequence diagram showing the flow until the recipient registers the slip number in the in-vehicle device 100. As shown in FIG. FIG. 5 is a sequence diagram showing the flow of processing after registering the slip number.
In the following description, each functional unit of the recording system 1000 shown in FIG. 1 will be used as appropriate. Also, as in the example of FIG. 3, it is assumed that the delivery person 60 delivers the package 70 .

First, referring to FIG. 4, the flow until the recipient registers the slip number in the in-vehicle device 100 will be described. The recipient terminal 80 receives an operation to switch to the parcel waiting mode from the recipient (S101). The recipient terminal 80 issues a switching request to the in-vehicle device 100 to switch the in-vehicle device 100 to the parcel waiting mode (S102).

In the in-vehicle device 100, the photographing control unit 140 switches the state of the in-vehicle device 100 to the luggage standby mode (S103). The imaging control unit 140 may notify the recipient terminal 80 that switching to the parcel waiting mode has been completed.

The payee terminal 80 accepts a slip number registration operation from the payee (S104). The recipient terminal 80 transmits a registration request together with the slip number to the in-vehicle device 100 (S105). In the in-vehicle device 100, the registration unit 110 registers the transmitted slip number in the recording unit 190 as the slip number information 191 (S106). If multiple storage locations are assumed, the recipient may register the storage location of the parcel 70 along with the slip number. Here, it is assumed that the recipient has registered trunk 301 as the storage location for package 70 .

Next, with reference to FIG. 5, the flow of processing after registering the slip number will be described.
The in-vehicle device 100 starts the normal monitoring mode in the imaging control unit 140 (S201). The imaging control unit 140 may start the normal monitoring mode by detecting that the vehicle 50 is parked, or may start the normal monitoring mode according to an instruction from the recipient terminal 80 .

When the normal monitoring mode is started, the imaging control unit 140 controls the imaging unit 400 so that the imaging unit 400 always performs imaging. The photographing control unit 140 deletes the photographed image when the vehicle condition of the vehicle 50 does not change, and records the photographed images of a predetermined time before and after the change in the recording unit 190 when the vehicle condition changes.

The delivery person 60 moves by a delivery vehicle or the like based on the description contents of the slip 75 attached to the package 70 and carries the package 70 to the vicinity of the vehicle 50 . The delivery man 60 puts his hand on the trunk 301 of the vehicle 50 (S202).

In the vehicle 50, the acceleration sensor 240 detects that the vehicle 50 is impacted by detecting an acceleration equal to or greater than a predetermined threshold. The acceleration sensor 240 notifies the in-vehicle device 100 to that effect (S203).

In the in-vehicle device 100, the photographing control unit 140 starts recording the photographed image when receiving the notification that the trunk 301 has been impacted (S204). As a result, the recording unit 190 records, as a captured image 193, a captured image from before the delivery man 60 puts his hand on the trunk 301. FIG.

The delivery person 60 inputs the slip number to the in-vehicle device 100 (S205). For example, the delivery person 60 brings the parcel 70 closer to the rear camera 430 so that the slip 75 is included in the shooting range of the rear camera 430 . Rear camera 430 captures a range including slip 75 and outputs the captured image to authentication unit 120 .

In the in-vehicle device 100, the authentication unit 120 reads the slip number from the captured image (S206). A well-known image recognition technique may be used to read the slip number. The authentication unit 120 refers to slip number information 191, which is registration information registered in advance. The authentication unit 120 compares the slip number read by the rear camera 430 with the registered slip number information 191 to authenticate the package 70 (S207). If the read slip number matches the slip number information 191, the authentication unit 120 determines that the authentication has succeeded, and otherwise determines that the authentication has failed.

Here, the photographing control unit 140 performs authentication using the slip number, but may perform face authentication of the delivery man 60 or authentication using the employee number. When performing face authentication, the delivery man 60 brings his face closer to the rear camera 430 so that his face is included in the imaging range of the rear camera 430 . Also, when performing authentication by the employee number of the delivery person 60 , the delivery person 60 brings an employee ID card or the like close to the rear camera 430 so that the employee number is included in the imaging range of the rear camera 430 . The rear camera 430 photographs the face of the delivery person 60 or the employee ID card in the same manner as the slip number, and outputs the photographed image to the authentication unit 120 . The authentication unit 120 refers to the delivery person information 192 and authenticates the delivery person 60 . Note that the front camera 410 or the vehicle interior camera 420 may be used instead of the rear camera 430 .

The authentication unit 120 determines whether or not the package 70 has been successfully authenticated (S208). If the authentication unit 120 determines that the authentication has failed (NO in S208), the process returns to step S206. When the authentication unit 120 determines that the authentication has succeeded (YES in S208), the authentication unit 120 requests the lock control unit 350 of the vehicle 50 to unlock the trunk 301 (S209).

The lock control unit 350 receives the unlock request from the authentication unit 120 and unlocks the trunk 301 (S210). The lock control unit 350 notifies the in-vehicle device 100 that the trunk 301 has been unlocked (S211). The delivery person 60 puts the parcel 70 in the trunk 301 and closes the trunk 301 (S212). Lock control unit 350 locks trunk 301 (S213). The locking control unit 350 notifies the in-vehicle device 100 that the trunk 301 has been locked (S214).

In the in-vehicle device 100, the storage detection unit 130 receives a notification that the trunk 301 has been unlocked due to successful authentication and then a notification that the trunk 301 has been locked, so that the luggage 70 is stored in the trunk 301. It detects that it has been done (S215). The imaging control unit 140 terminates recording in the normal monitoring mode (S216). The imaging control unit 140 may continue recording until a predetermined time has passed since the trunk 301 was locked.

The imaging control unit 140 starts the parcel monitoring mode (S217). In the baggage monitoring mode, as described with reference to FIG. 2, the imaging control section 140 controls the imaging section 400 so as to perform imaging under imaging conditions different from those in the normal monitoring mode. For example, the imaging control unit 140 controls the imaging unit 400 so as to increase the bit rate, frame rate, or resolution, and control so as to increase the imaging quality.

Further, the imaging control unit 140 may control the imaging unit 400 so that the sensitivity of the recording start trigger is higher than that in the normal monitoring mode. The imaging control unit 140 sets the sensitivity with which the sensor unit 200 detects changes in vehicle conditions to be higher than in the normal monitoring mode. For example, if a predetermined threshold value is set for acceleration for detecting an impact on the vehicle 50, the imaging control unit 140 sets a lower threshold value in the parcel monitoring mode than in the normal monitoring mode. Thereby, an impact can be detected with higher sensitivity.

Further, the imaging control unit 140 may perform control according to the type of sensor. For example, in the cargo monitoring mode, more sensors than in the normal monitoring mode are used to detect changes in vehicle conditions. As a result, the imaging control unit 140 can increase the sensitivity of the sensor that triggers the start of recording.

In the in-vehicle device 100, the storage detection unit 130 notifies the recipient terminal 80 that the luggage 70 has been stored in the trunk 301 (S218). The in-vehicle device 100 may notify after a predetermined time has passed since the trunk 301 was locked. As a result, even when the trunk 301 is unlocked and locked multiple times, the notification can be made only once.

In addition, the storage detection unit 130 may compare the number of stored parcels with the number of pre-registered parcels, and notify the recipient terminal 80 according to the comparison result. The storage detection unit 130 counts the number of packages stored based on the number of slip numbers successfully authenticated, the number of packages recognized by image recognition, or the number of packages based on the weight detected by the weight sensor 230. good.

In the in-vehicle device 100, the authentication unit 120 may manage the slip number so that the slip number used for authentication cannot be used for authentication again after a predetermined time has elapsed since the package 70 was received. For example, the authentication unit 120 deletes the slip number information 191 corresponding to the authenticated slip number. As a result, it becomes impossible to unlock the trunk 301 using the same slip number, so the crime prevention effect can be further enhanced.

As described above, in the recording system 1000 according to the present embodiment, the registration unit 110 of the in-vehicle device 100 records in advance the identification information of the item to be delivered or the delivery person as registration information. The authentication unit 120 of the in-vehicle device 100 can authenticate the delivery item or the delivery person by comparing the identification information acquired at the time of delivery with the registered information. Since the slip number of the delivery item can be used as the registration information, the recording system 1000 can perform authentication without separately handing over a code for authentication to the deliverer. In addition, since the in-vehicle device 100 and the recipient's terminal can communicate without going through the Internet, the recipient can safely register the registration information.

Further, in the recording system 1000, the lock control unit 350 unlocks the storage unit 300 in response to successful authentication, and locks the storage unit 300 again after storage of the delivery item. Therefore, the recipient can safely receive the delivery.

The storage detection unit 130 of the in-vehicle device 100 detects that the delivery item has been stored when the storage unit 300 is unlocked due to successful authentication and then locked. The photographing control unit 140 of the in-vehicle device 100 controls the photographing unit 400 so that when the receipt of the delivery is detected, the photographing is performed under different photographing conditions from when the receipt of the delivery is not detected.

For example, the imaging control unit 140 controls the imaging unit 400 so that the captured image has a higher image quality after the storage of the delivery item is detected. Alternatively, the imaging control unit 140 controls the imaging unit 400 so as to increase the sensitivity of the recording start trigger for starting the recording of the captured image after the receipt of the delivery item is detected. By doing so, recording can be started even if the change in the vehicle condition occurring in the vehicle 50 is small after receiving the delivered item compared to before receiving the delivered item.

With such a configuration, according to the recording system 1000 according to this embodiment, it is possible to provide a safe delivery service without changing the current distribution system. Moreover, according to the recording system 1000 according to the present embodiment, it is possible to appropriately monitor and record the baggage not only at the timing before the baggage is stored but also at the timing after the baggage is stored. becomes.

Each functional component of the recording system 1000 described above may be implemented by hardware (eg, hardwired electronic circuit) that implements each functional component, or may be a combination of hardware and software (eg, : a combination of an electronic circuit and a program that controls it, etc.). For example, the present disclosure can also implement arbitrary processing by causing a CPU (Central Processing Unit) to execute a computer program.

A program includes instructions (or software code) that, when read into a computer, cause the computer to perform one or more of the functions described in the embodiments. The program may be stored in a non-transitory computer-readable medium or tangible storage medium. By way of example, and not limitation, computer readable media or tangible storage media may include random-access memory (RAM), read-only memory (ROM), flash memory, solid-state drives (SSD) or other memory technology, CDs -ROM, digital versatile disc (DVD), Blu-ray disc or other optical disc storage, magnetic cassette, magnetic tape, magnetic disc storage or other magnetic storage device. The program may be transmitted on a transitory computer-readable medium or communication medium. By way of example, and not limitation, transitory computer readable media or communication media include electrical, optical, acoustic, or other forms of propagated signals.

Note that the present disclosure is not limited to the above-described embodiments, and can be modified as appropriate without departing from the scope of the present disclosure. For example, in the above description, the configuration in which the recording unit 190 of the in-vehicle device 100 records the captured image is used, but the configuration is not limited to this. The in-vehicle device 100 may transmit the captured image to a predetermined server via a network, and record the captured image in the server. Similarly, the slip number information 191 and the delivery person information 192 recorded in the recording unit 190 may be managed by a predetermined server.

Further, the in-vehicle device 100 may be configured to control various devices mounted on the vehicle 50 according to the type of the delivered item when the storage detection unit 130 detects the delivered item. The delivery item type is information related to the management method of the delivery item, such as refrigerated items, frozen items, or normal temperature items. If the item to be delivered is a refrigerated item or a frozen item, the registration unit 110 registers that fact in advance in association with the slip number or the like.

When the storage detection unit 130 detects the delivery item, the in-vehicle device 100 outputs an operation request to the control device that controls the air conditioner of the vehicle 50 so that the air conditioner performs cooling operation. Upon receiving the operation request from the in-vehicle device 100, the vehicle 50 starts cooling operation. By doing so, it is possible to prevent deterioration in the quality of the items to be delivered.

Note that the in-vehicle device 100 may determine whether or not to operate the air conditioner according to the temperature of the delivered item by providing a sensor capable of detecting the temperature of the delivered item. As a result, the in-vehicle device 100 can start the refrigerating operation without registering in advance that the product is a refrigerated product or a frozen product. Further, the in-vehicle device 100 may determine whether or not to operate the air conditioner according to the temperature inside the vehicle 50 . As a result, even normal temperature products can be prevented from being subjected to unexpected temperature changes.
