Description

The present invention relates to a security inspection confirmation system for confirming whether or not a security inspection has been carried out during boarding procedures at an airport, a security inspection confirmation device, and a security inspection confirmation method.

A system has been introduced to confirm whether or not a security checkpoint has been inspected at a security checkpoint that inspects baggage at the airport by checking the security checkpoint distributed to passengers. However, even though the security checkpoint was issued at the security checkpoint, there was a problem that some people passed through the security checkpoint without undergoing the security inspection. Therefore, techniques for strengthening security inspections at airports have been studied (for example, Patent Document 1 and Non-Patent Document 1).

Patent Document 1 discloses a boarding security check system that performs a security check of passengers and carry-on baggage performed when boarding an aircraft at an airport by a computer. This boarding security check system reads the data recorded on the boarding pass or customer card and the biometric information of the passenger, and collates the boarding reservation information registered at the time of boarding reservation to perform admission authentication.

The technology described in Non-Patent Document 1 conducts security inspections at security checkpoints for flight passengers and hands them a security inspection certificate for boarding for the purpose of strengthening security at security checkpoints and boarding gates at airports. I have confirmed my possession of a security checkpoint by mouth.

International Publication No. 2005/051511

ANA, "Issuance of Security Inspection Certificate / Boarding Information Form from December 2016", [Search on October 2, 2017], Internet <URL: https://www.ana.co.jp/domestic /prepare/checkin/proof/renewal.html ＞

In the technique described in Patent Document 1, by registering a face image and passenger information in advance at a security checkpoint or the like, it is possible to restrict admission at the boarding gate after that. It is not possible to confirm whether or not the security inspection has been carried out. Further, in the technique described in Non-Patent Document 1, at the security checkpoint, the passage of the passenger through the gate provided at the security checkpoint and the issuance of the inspection certificate to the passenger are not linked, so that the security inspection certificate is used. It is possible to slip through without conducting a security check on what you have.

Therefore, there is a need for technology that can confirm whether or not a security inspection has been conducted at an airport.

The feature configuration of the security inspection confirmation system according to the present invention is a security inspection confirmation system for confirming whether or not a security inspection has been performed during boarding procedures at an airport, and includes at least the face of a person who has undergone the security inspection. The first image pickup unit that acquires the first image pickup image and the face image of the person included in the first image pickup image acquired by the first image pickup unit or the first face image data that is a feature amount of the face image. A storage unit for storing, a second imaging unit that acquires a second captured image including at least the face of a passenger boarding an aircraft in the passenger passage passage of the airport, and the passenger included in the second captured image. The face image or the second face image data which is the feature amount of the face image is collated with the first face image data, and the notification unit for notifying the collation result in the collation unit is provided . The first imaging unit is at the point of acquiring only the first captured image of a person who conforms to the security inspection .
With such a feature configuration, by collating the first face image data of the person who has undergone the security inspection with the second face image data of the passenger, it is easy to determine whether or not the security inspection has been performed based on the collation result. You can check. Then, it is notified that the first face image data matching the second face image data is not stored in the storage unit and that the first face image data matching the second face image data is stored in the storage unit. Since the department notifies you, you can identify people who have not undergone security inspections and those who have undergone security inspections. Therefore, it is possible to strengthen security inspections at airports.
Further, with such a configuration, since the first captured image of the person who does not conform to the security inspection is not acquired, the first face image data that is not used for collation is not generated. Therefore, it is possible to suppress an increase in the amount of data stored in the storage unit.

Another characteristic configuration of the security inspection confirmation system according to the present invention is a security inspection confirmation system for confirming whether or not a security inspection has been performed during boarding procedures at an airport, and at least the face of a person who has undergone the security inspection. A first image pickup unit that acquires a first image captured image including the above, and a face image of the person included in the first image pickup image acquired by the first image pickup unit, or a first face image that is a feature amount of the face image. A storage unit that stores data, a second imaging unit that acquires at least a second captured image including at least the face of a passenger boarding an aircraft in a passenger passage passage of the airport, and the second imaging unit included in the second captured image. A collation unit that collates the occupant's face image or the second face image data, which is a feature amount of the face image, with the first face image data, and a notification unit that notifies the result of the collation in the collation unit. The storage unit stores only the first face image data of the person conforming to the security inspection among the first face image data of the person included in the first image captured image acquired by the first image pickup unit. There is a point to do.
With such a feature configuration, by collating the first face image data of the person who has undergone the security inspection with the second face image data of the passenger, it is easy to determine whether or not the security inspection has been performed based on the collation result. You can check. Then, it is notified that the first face image data matching the second face image data is not stored in the storage unit and that the first face image data matching the second face image data is stored in the storage unit. Since the department notifies you, you can identify people who have not undergone security inspections and those who have undergone security inspections. Therefore, it is possible to strengthen security inspections at airports.
Further, even with such a configuration, since the first face image data of the person who does not conform to the security inspection is not stored, it is possible to suppress an increase in the amount of data stored in the storage unit.

For example, the passenger passageway can be configured as a boarding gate.

With such a configuration, it is determined whether or not the passenger has undergone a security inspection at a boarding gate that can identify the passenger, so that it is possible to reliably prevent a person who has not undergone the security inspection from boarding the aircraft. It will be possible.

Further, the notification unit can be configured to display the face image of the passenger at the time of notification. At this time, the storage unit may store the face image of the passenger included in the second captured image as face image data.

With such a configuration, it is possible for airport personnel to easily identify people who have not undergone security inspections.

Further, the notification unit can be configured to display an entire image including the entire image of the passenger. At this time, the storage unit may store the entire image including the entire image of the passenger included in the second captured image as the entire image data.

With such a configuration, it is possible for airport personnel to easily grasp the whole picture of people who have not undergone security inspections.

Further, the first face image data is preferably stored in the storage unit without being associated with the boarding ticket information of the person included in the first captured image.

With such a configuration, it is possible to suppress an increase in the amount of data stored in the storage unit.

Alternatively, the first face image data may be associated with the boarding ticket information of the person included in the first captured image and stored in the storage unit.

With such a configuration, the number of first face image data collated by the collation unit can be reduced according to the boarding ticket, so that the load related to collation can be reduced. In particular, since the boarding ticket information is associated with the boarding gate, the number of first face image data required for collation can be limited to the second face image data acquired at a specific boarding gate, which is required for collation. It is possible to shorten the time.

1. 1. Security Inspection Confirmation System The security inspection confirmation system according to the present invention has a function of confirming whether or not a security inspection has been carried out during boarding procedures at an airport. Hereinafter, the security inspection confirmation system 1 of the present embodiment will be described.

FIG. 1 is a diagram schematically showing the configuration of the security inspection confirmation system 1. As shown in FIG. 1, the security inspection confirmation system 1 is configured to include each functional unit of a first image pickup unit 11, a storage unit 12, a second image pickup unit 13, a collation unit 14, and a notification unit 15. The functional unit is constructed of hardware, software, or both with a CPU as a core member in order to perform processing related to confirmation of whether or not a security inspection has been performed.

Here, at the airport, for the safe operation of the aircraft, it is obligatory to carry out a security inspection to inspect the passengers on the aircraft and carry-on baggage before boarding. At the security checkpoint, the boarding pass and passport are first checked. Next, the passenger is subjected to metal detection by a metal detector, and the baggage is X-ray inspected by an X-ray inspection device.

The metal detection is performed, for example, by one person who is about to board the aircraft passing through the metal detection gate 2 constituting the metal detector. A plurality of such metal detection gates 2 are provided at the airport, and a person who intends to board an aircraft need only pass through any one of the plurality of metal detection gates 2.

The first imaging unit 11 acquires a first captured image including at least the face of a person who has undergone a security inspection. The person who has undergone the security inspection is a person who has passed through the metal detection gate 2 described above. The first image pickup unit 11 is arranged so that the face of a person who has passed through the metal detection gate 2 is included in the image pickup range. As a result, the first imaging unit 11 can acquire the first captured image including the face of a person who has passed through the metal detection gate 2. Such a first image pickup unit 11 can be configured by a camera.

FIG. 2 shows a mode in which the first imaging unit 11 acquires a first captured image including a human face passing through the metal detection gate 2. As shown in FIG. 2, the metal detection gate 2 is provided with a passage sensor 3 for detecting the passage of a person at the metal detection gate 2, and when the passage sensor 3 detects the passage of a person at the metal detection gate 2, the passage sensor 3 is provided. It is preferable that the first imaging unit 11 is configured to acquire the first captured image. In such a passage sensor 3, for example, the passing portion of the metal detection gate 2 is irradiated with infrared rays (indicated by a alternate long and short dash line in FIG. 2), and when the infrared rays are blocked, the passenger enters the metal detection gate. It can be configured to detect that it has passed 2. Of course, it is also possible to detect the passage of the occupant through the metal detection gate 2 by another method. With this configuration, it is possible to acquire the first captured image including the face of a person passing through the metal detection gate 2 by a walkthrough.

The process of acquiring at least the first captured image including the face of a person who has undergone such a security inspection is the first imaging in the security inspection confirmation method for confirming whether or not the security inspection has been performed during the boarding procedure at the airport. It is called processing. The first captured image acquired by the first imaging unit 11 is transmitted to the storage unit 12, which will be described later.

Returning to FIG. 1, the storage unit 12 stores the face image of a person included in the first captured image acquired by the first imaging unit 11 or the first face image data which is a feature amount of the face image. The first captured image acquired by the first imaging unit 11 is transmitted to the storage unit 12, and the transmitted first captured image includes at least the face of the occupant. The face image is an image of the passenger's face. The feature amount of the face image is an amount obtained by quantifying the facial features of the person (passenger) in the face image. These face images and feature quantities of the face images are treated as the first face image data in the security inspection confirmation system 1, and the first face image data is stored in the storage unit 12. Therefore, in the following, when it is not necessary to distinguish between the face image and the feature amount of the face image, it will be described as the first face image data.

FIG. 3 shows an example of the first face image data stored in the storage unit 12. As shown in FIG. 3, in the present embodiment, the storage unit 12 stores the first face image data in association with the time (imaging time) when the first image captured image is acquired by the first image pickup unit 11. To go. Therefore, a plurality of first face image data are sequentially stored in the storage unit 12. When a plurality of first image pickup units 11 are provided, identification information that can identify the first image pickup unit 11 may be stored in association with the first face image data.

The process of storing the first face image data included in the first captured image acquired in the first image pickup process in the storage unit 12 is referred to as a storage process in the security inspection confirmation method.

In the storage unit 12, the first face image data is stored without being associated with the boarding ticket information of the person included in the first captured image. The person included in the first captured image is a passenger who has undergone a security inspection and is included in the first captured image. The boarding ticket information corresponds to the identification information of the aircraft on which the passenger can board, that is, the flight number and the seat information on the aircraft, which are associated with the boarding ticket of the passenger. In the present embodiment, the first face image data is stored in the storage unit 12 without associating these information. Therefore, it is possible to suppress an increase in the amount of data stored in the storage unit 12.

Of course, the storage unit 12 is configured to store only the first face image data of the person who conforms to the security inspection among the first face image data included in the first captured image acquired by the first imaging unit 11. It is also possible. As described above, the first captured image is acquired when a person passes through the metal detection gate 2, and is sequentially transmitted to the storage unit 12. On the other hand, in the security inspection, the same person may be re-inspected for some reason, for example, possession of a metal object. In this case, the metal detection gate 2 is passed through again, but the first image pickup image is acquired by the first image pickup unit 11 at that time as well. Therefore, in order to suppress an increase in the amount of data of the first face image data stored in the storage unit 12, the storage unit 12 contains the first face image data included in the first captured image acquired by the first imaging unit 11. Of these, it is preferable to configure so that only the first face image data of the person who conforms to the security inspection is stored, and the first face image data of the person who does not conform to the security inspection (the person who has been re-inspected) is not stored. Is.

Of course, in addition to or instead of the above, the first imaging unit 11 is configured to acquire only the first captured image of a person who conforms to the security inspection recognized by the lamp or the like provided in the metal detection gate 2. It is also possible to do. Even in this case, it is possible to suppress an increase in the amount of first face image data stored in the storage unit 12.

Returning to FIG. 1, the second imaging unit 13 acquires a second captured image including at least the face of the passenger boarding the aircraft in the passenger passage passage of the airport. The passenger passage of an airport is a passage through which a passenger passes, and is a passage through which a passenger who has undergone a security inspection at a security checkpoint passes before boarding an aircraft. Generally, at airports, security-checked passengers are passed through the boarding gate when boarding an aircraft. In this embodiment, this boarding gate corresponds to a passenger passage.

A boarding gate is provided for each gate on which the aircraft is boarded. Therefore, there are multiple boarding gates at the airport. Each boarding gate is provided with a boarding gate 4 for checking the boarding pass of the passenger. The second imaging unit 13 is arranged so that at least the face of the passenger is included in the imaging range when the passenger passes through the boarding gate 4. Therefore, in the present embodiment, a plurality of second imaging units 13 are arranged in the passenger passage passage. As a result, the second image pickup unit 13 can acquire the second captured image including the face of the passenger who has passed through any of the boarding gates 4 among the plurality of boarding gates 4. Such a second image pickup unit 13 can be configured by a camera in the same manner as the first image pickup unit 11.

FIG. 4 shows a mode in which the second imaging unit 13 acquires a second captured image including the face of a passenger passing through the boarding gate 4. As shown in FIG. 4, a passage sensor (not shown) for detecting the passage of a person at the boarding gate 4 is provided at the boarding gate 4, and when the passage sensor detects the passage of a person at the boarding gate 4, the passage sensor is provided. It is preferable that the second imaging unit 13 is configured to acquire the second captured image. Further, instead of the passage sensor, it is also possible to detect by presenting the boarding ticket to the reading device (not shown) of the boarding gate 4 when the passenger passes through the boarding gate 4. Of course, it is also possible to detect the passage of the passenger through the boarding gate 4 by another method. With this configuration, it is possible to acquire a second captured image including the face of the passenger passing through the boarding gate 4 by a walkthrough.

The process of acquiring a second captured image including at least the face of a passenger boarding an aircraft in such a passenger passage of an airport is referred to as a second imaging process in a security inspection confirmation method. The second captured image acquired by the second imaging unit 13 is transmitted to the collating unit 14, which will be described later.

Returning to FIG. 1, the collation unit 14 collates the passenger's face image included in the second captured image or the second face image data which is a feature amount of the face image with the first face image data. As described above, in the security inspection confirmation system 1, the passenger's face image and the feature amount of the face image in the first captured image are treated as the first face image data. In the present embodiment, the face image of the passenger and the feature amount of the face image in the second captured image are treated as the second face image data. The collation unit 14 collates the second face image data with the first face image data of the person who has undergone the security inspection included in the first captured image stored in the storage unit 12.

In the collation of the first face image data and the second face image data by the collating unit 14, when the degree of matching between the first face image data and the second face image data is equal to or more than a preset value, the first face image It is determined that the data and the second face image data match. Therefore, in the collation by the collation unit 14, it is determined that not only the matching is perfect but also the matching is performed even if there is a certain difference. As a result, it is possible to determine whether or not the person is the same person even if the elevation / depression angle and the azimuth angle with respect to the image pickup surface of the person's face included in the first image pickup image and the second image pickup image are different from each other. It will be possible.

Here, in the storage unit 12, the first face image data of the number of people (passengers) who have passed through the metal detection gate 2 is stored in the metal detection gate 2 of the security checkpoint at the airport. Therefore, as shown in FIG. 5, the collation unit 14 sequentially collates one second face image data with the plurality of first face image data stored in the storage unit 12, and sequentially collates the second face image data. When the first face image data matching the image data is detected (in the case of the determination “◯” in FIG. 5), the collation of the second face image data is terminated. When the first face image data that matches the second face image data is detected in this way, the collating unit 14 indicates that the first face image data has been detected at the time of detection (hereinafter, the information indicating that the first face image data has been detected). "Inspection information") is transmitted to the notification unit 15 described later. In this case, the remaining first face image data stored in the storage unit 12 is not subject to collation.

On the other hand, as shown in FIG. 6, the second face image data is collated with all the first face image data stored in the storage unit 12, and the first face image data that matches the second face image data is obtained. Even if it is not detected (when all the determinations are "x"), the collation of the second face image data is terminated. When the first face image data matching the second face image data is not detected in this way, the collation unit 14 indicates that the first face image data was not detected (hereinafter, "undetected information"). ”) Is transmitted to the notification unit 15 described later.

Here, the first captured images are sequentially acquired at the security checkpoint of the airport. Therefore, even after the second captured image is acquired, there is a possibility that new first face image data is sequentially stored in the storage unit 12. On the other hand, in the present embodiment, the first face image data is stored in the storage unit 12 in association with the imaging time. Therefore, among the first face image data stored in the storage unit 12, the collation unit 14 collates the first face image data associated with the imaging time before the time when the second face image data is collated. Of the first face image data stored in the storage unit 12, the first face image data associated with the imaging time after the time when the second face image data is collated may be excluded from the collation target. ..

In the collation by the collation unit 14, in addition to the above-mentioned first face image data and the second face image data, for example, wearing objects (for example, glasses, hats, accessories, etc.) worn on the face are also used for collation. Is possible. Further, the collation method is not particularly limited, and a known method can be used. The process of collating the passenger's face image included in the second captured image or the second face image data which is the feature amount of the face image with the first face image data is the collation process in the security inspection confirmation method. Is called.

Returning to FIG. 1, the notification unit 15 notifies the result of the collation by the collation unit 14. For example, when the notification unit 15 does not store the first face image data that matches the second face image data in the storage unit 12, the first face image data that matches the second face image data is stored in the storage unit 12. It can be configured to notify that it is not stored in. In such a case, the above-mentioned detection information or undetected information is transmitted to the notification unit 15 as a result of the collation by the collation unit 14. The case where the first face image data matching the second face image data of the passenger included in the second captured image is not stored in the storage unit 12 is the case where the undetected information is transmitted from the collating unit 14. .. That is, it is a case where the first face image data matching the second face image data is not detected. In this case, the notification unit 15 notifies that the passenger with the face included in the second captured image has not undergone the security inspection.

Here, in the present embodiment, the security inspection confirmation system 1 is used to confirm whether or not the passenger on the aircraft passing through the boarding gate 4 has undergone a security inspection at the security checkpoint. As described above, at an airport, a plurality of boarding gates 4 may be provided according to the destinations and boarding gates of a plurality of aircraft. In the present embodiment, since the second captured image is acquired at the boarding gate 4, the notification unit 15 is provided at each of the plurality of boarding gates 4. As a result, the passenger passing through the boarding gate 4 can be notified on the spot whether or not he / she has undergone a security inspection.

As shown in FIG. 7, the notification unit 15 can be configured as, for example, a terminal with a display screen. As a result, when "undetected information" is transmitted, for example, a sound such as "No security inspection history" is output, or a display such as "No security inspection history" is displayed on the display screen. It can be notified and can be known to airport employees, security guards, and even the relevant passengers themselves. It is also possible to simply output a buzzer-like sound, light, or the like for notification. Then, the airport official can request the person who has not undergone the security inspection to show the security inspection certificate and judge whether or not to board. Further, the notification unit 15 can be configured to transmit the collation result of the collation unit 14 to a mobile terminal (for example, a smartphone or a tablet computer) owned by an airport person (for example, a security guard) and notify the notification unit.

The notification unit 15 can also be configured to display a face image of the occupant at the time of notification. Displaying the face image of the passenger means displaying the second captured image on the display screen of the notification unit 15. By displaying such a passenger's face image on the display screen, airport employees and security guards can identify the relevant passenger and not lose sight of it. In this case, the face image of the passenger included in the second captured image may be stored in the storage unit 12 as face image data. By storing the face image of the person (passenger) displayed on the display screen in the storage unit 12 as face image data in this way, it is possible to easily grasp the person as a person requiring attention in the future.

Further, when the first face image data matching the second face image data is stored in the storage unit 12, the notification unit 15 stores the first face image data matching the second face image data in the storage unit 12. It can also be configured to notify that it is stored in 12. In such a case, "detection information" is transmitted to the notification unit 15. When the "detection information" is transmitted, the notification unit 15 outputs, for example, a sound indicating "there is a security inspection history" as shown in FIG. 8, or the "security inspection history" is displayed on the display screen. It can be notified by displaying a message such as "There was a problem", so that airport employees, security guards, and even the relevant passengers themselves can understand it. It is also possible to display the "first captured image" and the "second captured image" on the display screen. As a result, airport personnel can omit the confirmation of the security inspection certificate at the boarding gate, so that it is possible to facilitate boarding and prevent omission of confirmation of the security inspection.

The process of notifying the collation result in such a collation process is referred to as a notification process in the security inspection confirmation method.

2. 2. Security inspection confirmation device Next, the security inspection confirmation device will be described. Similar to the security inspection confirmation system 1 described above, the security inspection confirmation device has a function of confirming whether or not a security inspection has been performed during boarding procedures at an airport. FIG. 9 is a block diagram schematically showing the configuration of the security inspection confirmation device 9 according to the present embodiment.

As shown in FIG. 9, the security inspection confirmation device 9 includes each functional unit of a storage unit 12, a collation unit 14, a first captured image acquisition unit 16, a second captured image acquisition unit 17, and a collation result output unit 18. These functional units are constructed of hardware, software, or both with a CPU as a core member in order to perform processing related to confirmation of whether or not a security inspection has been performed.

The security inspection confirmation device 9 includes a first image acquisition unit 16 in place of the first image pickup unit 11 and a second image acquisition unit 17 in place of the second image pickup unit 13 for the security inspection confirmation system 1. The difference is that the collation result output unit 18 is provided instead of the notification unit 15. Since the storage unit 12 and the collation unit 14 are the same as the security inspection confirmation system 1, the description thereof will be omitted.

The first captured image acquisition unit 16 acquires a first captured image including at least the face of a person who has undergone a security inspection from the first imaging unit 11. The first imaging unit 11 is a camera, and acquires a first captured image including the face of a person passing through the metal detection gate 2 of the airport.
