Description

Accessor inspection system using X-ray image and access pass {SYSTEM FOR ENTRANT INSPECTION USING X-RAY IMAGE AND ACCESS PASS}

The present invention relates to an occupant inspection system using an X-ray image and an access pass.

In general, when checking people at international airports, domestic airports, or businesses, security personnel compare the face image of the pass with the entrants with the naked eye to determine that they are the same person. To solve this problem, the face image taken at the time the pass was issued to the regular pass holder entering the security area and the face image taken at the entrance when entering the security area are compared to confirm that they are the same person, and then allowed to enter. There is no face image taken at the time of issuance, so an airport security area access control system was proposed that allows access to be controlled by confirming that the person is the same person when moving and entering the security area based on the face image first taken at the entrance at the time of entry.

However, since such a system was developed with a focus on the access control function for the number of people entering the protected area, there is a problem that it is not suitable for an access control environment in which a security search by security personnel or the like must be performed.

In addition, it was developed to check only the presence/absence of permission to enter the security area for those waiting to enter the security area without considering the environment that requires security screening, and to allow access to the security area unconditionally. In addition, even though the security screening of the preceding entrants (search examiners) has not been completed, a large number of people waiting to enter the security area at the same time ignore the control of security personnel, and aviation security accidents such as “unauthorized entry into the security area” are occurring. The point is that it is vulnerable to security. Therefore, we tried to solve the problem by controlling and recognizing the pass of the entrant if the security check of the preceding entrant was not completed by additionally deploying a dedicated control agent at the entrance to control and monitor the unauthorized access of the waiting person. However, despite the control of the control personnel during rush hour, cases of recognizing the pass and entering without permission are constantly occurring.

In addition, even though the security screening of the preceding entrants (search examiners) has not been completed, a large number of people waiting to enter the security area at the same time ignoring the instructions of the control personnel, causing accidents such as access violations due to unauthorized entry into the security area. have.

In addition, due to a synchronization problem with the image display system, a large number of entrants entered the security area without permission, and a system error in which the pass information and the image at the time of issuance was displayed so that the security check officer confirms that the entrant is the same person continues to occur. In addition, although X-ray inspection of belongings is carried out at some exits, there is no system that displays pass information and images at the time of issuance so that the security check officer confirms that the person entering and leaving is the same person. Therefore, the level of security is significantly lower compared to the entrance.

In addition, it is difficult to detect terrorist goods and smuggling, and even after detection, it is difficult to accurately identify the owner of the goods (identified by the ability of evidence, x-ray images, etc.) There is a problem with contraband, and if it is not possible to detect contraband at the exit, it is practically impossible to detect after the fact as it is necessary to investigate all stored and managed information such as CCTV (closed-circuit television) and access records.

In addition, since there is no function to inquire information at the time of entry such as X-ray images and entry records for each entry, even if a suspected smuggling product is detected, if the exporter claims that the product was brought in when entering the security area, whether There is a problem that it is difficult to determine the data, and since it is a method that stores the generated data unconditionally, it is not possible to accurately classify the visitors and store the data individually, so there is a problem that it cannot be used efficiently.

The technology that is the background of the present invention is disclosed in Republic of Korea Patent Registration No. 10-1658484 (2016.09.21. Announcement).

The present invention has been derived to solve the above problems, and it is an object of the present invention to provide an occupant inspection system using an X-ray image and an access pass for restricting access using an X-ray image and a user's access card. .

According to an embodiment of the present invention, an access door, a card reader provided on one side of the door and recognizing an identification card from the person entering the door, a baggage scanner for photographing the inside of the luggage of the person using X-ray, the card reader, It is provided together and includes an image photographing device for photographing the occupants and a management server for matching and storing the occupant information, the X-ray image of the photographed baggage, and the photographed image of the occupant.

It may further include a CCTV provided at the entrance and exit of the baggage search machine and an alarm alarm provided on the upper side of the baggage search machine.

The management server compares the X-ray image of the baggage photographed at the entrance of the occupant with the X-ray image of the baggage photographed by the baggage scanner when the occupant exits, when the entrant exits the door, and determines whether the occupant exits. It can be judged and output to the monitor.

When it is determined that the exit of the person is impossible, the management server may provide a signal for stopping the operation of the baggage search machine and a signal for operating the alarm, etc. to the baggage search machine and the alarm alarm.

According to the present invention having the above method and characteristics, high-level search operation capability such as detection of illegal items or prohibited items by making a DB list of belongings of executives and employees entering and exiting an institution or business site while conducting a normal search operation and management support.

In addition, the system can be additionally set to the generally operated security checkpoint (especially X-Ray search equipment), and by using the secured DB, it is provided for downloading search images and writing reports, and furthermore, for use of educational materials for readers. can do.

In addition, by interlocking with the facial recognition system, it is possible to block the entry of unauthorized persons, and when an entrant exits, the image information retrieved at the time of entry is called at the same time to allow the operator to compare and contrast, thereby blocking the export of unauthorized items. can

In addition, it is possible to grasp the pattern of the goods possessed by the visitor by converting the X-ray scan image of the visitor's belongings into a DB.

1 is a block diagram illustrating an occupant inspection system according to an embodiment of the present invention, and FIG. 2 is a view showing an example of an occupant inspection system according to an embodiment of the present invention. As shown in FIGS. 1 and 2 , the access inspection system 100 according to an embodiment of the present invention includes an entrance door 110 , a card reader 120 , an image capturing device 130 , a baggage searcher 140 , and a management server 150 . ), a CCTV 160 , an alarm light 170 and a display unit 180 .

First, the door 110 determines the temperature of the entrant and the presence or absence of metal possession. In this case, the door 110 may be installed so that one person passes through. 3 is a view showing a door and a baggage search machine of the entrant inspection system according to an embodiment of the present invention. That is, as shown in FIG. 3 , the door 110 according to the embodiment of the present invention may be installed.

Next, the card reader 120 is provided on one side of the door 110, and recognizes the identification card from the person entering. That is, as shown in FIG. 2 , the card reader 120 may be provided on the entrance side and the exit side of the door 110 , respectively. Then, the visitor touches or tags the recognition card on the recognition part of the card reader 120 to recognize the recognition card by the card reader 120 .

Next, the image photographing apparatus 130 is provided together with the card reader 120, and photographs the person entering or leaving. That is, as shown in FIG. 2 , the face of the person who is currently photographing is output on the screen.

Next, the baggage detector 140 photographs the inside of the visitor's portable article through X-ray equipment. At this time, X-ray equipment is divided into small baggage search equipment and large cargo search equipment. It generates X-rays by applying high voltage to the anode of the vacuum tube, and a general cargo detector applies a voltage of 140,000 volts to the anode and cathode. The operation of the X-Ray scanning equipment generates X-Ray of the luggage moving on the conveyor, absorbs the beam with the detector, and displays it as an image. By digitizing two image processing, which is the actual atomic behavior of the retrieved baggage, it is classified as organic and inorganic, and the density of the object determines the color and body shape. Organic/inorganic materials with low density appear faint and pale, and organic/inorganic materials with high density appear dark and dark. The material classification of organic and inorganic materials can be confirmed by the different reactions when X-rays are radiated to the two materials.

Next, the management server 150 matches and stores the occupant information, the X-ray image of the photographed baggage, and the photographed image of the entrant. In this case, the visitor information may be information stored in the management server 140 together with the identification card information. In addition, when the information of the identification card tagged with the card reader 120 and the photographing information are different or absent from the previously stored information, the management server 140 provides an alarm sound to the alarm alarm lamp 170 to be described later.

In addition, when a rule violation or a suspicious article is present in the image captured through the baggage detector 150 , the corresponding information can be provided to the manager in a state in which the article is matched with the occupant information and stored.

Next, the CCTV 160 is provided at the baggage screening counter to photograph the luggage entering the luggage screening station 130, and the X-ray photographing is finished and the discharged luggage is photographed, and the management server 150 is X- Match it with the ray image and save it. At this time, CCTV is classified into a closed circuit system and an open circuit system as a TV television system that allows only a specific person to view an image by using a cable TV in a specific facility. The latter aims to deliver image information to an unspecified number of people, and TV broadcasting generally belongs to this category, whereas the former closed circuit system refers to a system that delivers image information to a specific user for a specific purpose. It is called closed circuit television, or CCTV.

Next, the alarm light 170 is provided above the baggage checker, and turns on a red light when unauthorized baggage or dangerous baggage is detected in the baggage checker 140 .

Next, the display unit 180 displays the X-ray image photographed through the baggage scanner 140 and the user information retrieved by the identification card together using the monitor so that the manager can check it.

Hereinafter, an occupant inspection method of the entrant inspection system according to an embodiment of the present invention will be described with reference to FIGS. 4 to 8 .

4 is a flowchart illustrating a method for inspecting an occupant according to an embodiment of the present invention. As shown in FIG. 4 , the method for inspecting an occupant according to an embodiment of the present invention includes a step of receiving an identification card from the entrant (S410), a step of receiving and photographing the entrant’s baggage (S420), and the identification card information and the photographing information of the luggage. It includes a step of matching and storing (S430) and a step of determining whether access is possible using the stored information (S440).

First, in the step S410 of receiving the identification card from the visitor, if the identification card (which may be an official ID or employee ID) carried by each visitor is recognized by the installed card reader 120, the management server 150 is The image photographing device 130 is used to photograph the person's face, and the photographed face and the information recognized by the card reader 120 are matched and stored. By matching and storing in this way, it can be determined whether the user is already registered. 5 is a diagram illustrating an example of visitor information according to an embodiment of the present invention.

That is, as shown in FIG. 5 , the visitor information obtainable through the identification card can check the name, card number, employee number, date of birth, affiliation and department. Or it could be an unauthorized person. In this way, it is possible to check whether the current entry or exit is approved through the entry and exit information.

Next, in the step (S420) of receiving and photographing the luggage of the visitor, if the luggage is carried by the visitor in step S410, the luggage is photographed through the baggage scanner 130. 6 is a view showing baggage photographed through X-ray according to an embodiment of the present invention, and FIG. 7 is a view showing a screen for inputting the type of baggage photographed through X-ray according to an embodiment of the present invention to be. That is, as shown in FIG. 6 , the management server 150 provides the image photographed through the baggage scanner 130 to the manager through the display unit 180 , and through X-ray from the manager as shown in FIG. 7 . Information about the photographed object is entered. In this way, you can store accurate baggage information by inputting information about your baggage through the manager.

Next, the step (S430) of matching and storing the identification card information and the photographing information of the luggage is stored in the management server 150 by matching the identification card information and the photographing information of the luggage, and is stored in the same identification card information. If there is photographic information of the luggage that is in it, it is saved together in the order of the date of photographing. As the X-ray image of the belongings of the occupant is continuously stored according to each identification card information, the pattern of the goods carried or carried by the entrant can be grasped. By checking the pattern of belongings of the entrant in this way, when the same entrant enters and exits with different belongings, the management server 150 can immediately provide the corresponding fact to the manager.

Next, in the step of determining whether access is possible using the stored information (S440), when an unauthorized item is found among the stored information, the manager turns the alarm light 170 on in green while the baggage scanner 140 is stopped. Change the color to red to prevent current entrants from entering.

In this way, it is possible to support high-level search operation capability and management, such as the detection of illegal items or prohibited items, by making the list of belongings of executives and employees entering and exiting the institution or business site at the same time as carrying out the normal search task.

In addition, the system can be additionally set to the generally operated security checkpoint (especially X-Ray search equipment), and by using the secured DB, it is provided for downloading search images and writing reports, and furthermore, for use of educational materials for readers. can do.

In addition, by interlocking with the facial recognition system, it is possible to block the entry of unauthorized persons, and when an entrant exits, the image information retrieved at the time of entry is called at the same time to allow the operator to compare and contrast, thereby blocking the export of unauthorized items. can

On the other hand, the entrant inspection system 100 needs to be enlarged so that the information being output on the stored screen can be further enlarged and viewed.

In order to satisfy the above requirements, the occupant inspection system 100 may include a client including a magnification interface for enlarging a selected area on the screen of the display unit 180 (are installed in the terminal and selected on the screen of the terminal). may include a client that includes an magnification interface that magnifies the .

Conventionally, to enlarge a specific area, the screen size is adjusted by tapping the touch screen (terminal screen) several times or by adjusting the distance between two fingers while touching the touch screen with two fingers (eg, thumb and index finger). control method was used.

When the touch screen is tapped several times, not only the part to be enlarged but also the other parts are enlarged. .

In addition, there is a problem in that it is difficult to grip a terminal (eg, a smartphone) when the distance between the two fingers is adjusted while the touch screen is touched with two fingers.

Also, recently, a terminal having a large size has been used. In particular, a user with a small hand size has a problem in that it is difficult to enlarge a specific part with only one finger, so that it is difficult to grip the terminal.

The magnification interface is designed to overcome the problems of the conventional method, and allows an area to be enlarged to be displayed on one screen, but can be enlarged using one finger. That is, through this, the desired specific part is enlarged, but the terminal is more easily gripped, so that damage to the terminal can be effectively suppressed.

Hereinafter, the enlarged interface will be described in more detail. Referring to FIG. 2 , when a first touch (touching the terminal screen with a finger, etc.) an arbitrary point on the terminal screen and maintaining the touch state for a preset time (for example, 3 seconds), a starting point Z1 is output, and the starting point When the touch (Z1) is re-touched (re-touched) for more than a preset time (for example, 3 seconds) after the touch of Z1 is released, the inner dotted line Z2 surrounding the starting point Z1 may be output.

Conversely, when the touch of the starting point Z1 is released and the touch is made again for less than the preset time, or when a point other than the starting point Z1 is touched on the terminal screen, the starting point Z1 may be deleted.

In addition, when the touch of the starting point Z1 is maintained for a preset time after the inner dotted line Z2 is output, the enlarged interface outputs an outer dotted line Z3 surrounding the inner dotted line Z2. can

In this case, the shapes of the inner region Z21 formed by the inner dotted line Z2 and the outer region Z31 formed by the outer dotted line Z3 may correspond to a reduced shape of the terminal screen.

As shown in [B] of FIG. 2 , the enlarged interface surrounds the outer dotted line Z3 when the touch of the starting point Z1 is maintained for more than a preset time after the outer dotted line Z3 is output. It goes without saying that the outermost dotted line Z4 may be output. That is, the number of dotted lines output according to the touch time of the starting point Z1 is not limited.

Referring to [A] of FIGS. 2 and 3 , the enlarged interface is configured such that the first point in the inner region Z21 (any point in the inner region Z21) exceeds a preset time (for example, 3 seconds). When touched, the first filling icon Z22 covering the inner region Z21 may be output.

In addition, the enlarged interface is dragged from the first point to the area between the inner dotted line Z2 and the outer dotted line Z3 (hereinafter referred to as the area between) (a finger touching a terminal screen such as a touch screen is dragged while touching the screen) ), a second filling icon Z32 covering the outer region Z31 may be output.

Similarly, when the outermost dotted line Z4 is output, the enlarged interface is between the inner dotted line Z2 and the outer dotted line Z3, and the third fill icon is dragged between the outermost dotted line Z4 and the outer dotted line Z3. can be printed out.

The above-described filling icons (the first filling icon Z22, the second filling icon Z32, etc.) may exemplarily have a translucent color.

If the second fill icon Z32 is reached, that is, when the area between the inner dotted line Z2 and the outer dotted line Z3 is touched and dragged to the inner area Z21, the second fill icon Z32 is It may be deleted and the first fill icon Z22 may be output.

In the enlarged interface, when the first fill icon Z22 is output (refer to [A] of FIG. 3), the inner region Z21 is restored as the touch of the first fill icon Z22 is released and re-touched. It can be enlarged by a set magnification (see [C] in FIG. 3).

If the second fill icon Z32 is output (see [B] in FIG. 3), the outer area Z31 is enlarged by a preset magnification as the touch of the second fill icon Z32 is released and re-touched. can

Here, the preset magnification refers to a magnification (eg, 2 times and 3 times, respectively) that becomes the maximum size within the limit in which the selected area (inner area Z21 or outer area Z31) on the terminal screen can be output on one screen. ) can be

As described above, since the present system includes an enlarged interface, even if the terminal is large and the size of a hand gripping the terminal is small, there is an advantage that a specific area can be enlarged with only one finger while holding the terminal with one hand.

To be more specific, the area to be enlarged by outputting dotted lines only by controlling the touch holding time of the starting point Z1 and touching/re-touching one starting point Z1 with one finger is one finger. You can preview with just the movement of your finger.

In addition, since the starting point Z1 is an arbitrary point at which the user selects the terminal screen, a specific part to be enlarged can be set by touching with only one finger while holding the terminal. Through this, there is an advantage that a separate operation for operating the magnification interface is not required because a separate start icon for generating the starting point Z1 is not required.

In addition, as described above, the starting point Z1 is output only when the touch state is maintained for a preset time after the first touch, so that a malfunction in which a part is enlarged by touching the terminal screen with an unintentional operation can be prevented, and the user can use the inner dotted line (Z2) It can be checked whether the touch state is maintained beyond a preset time after touching the starting point Z1 again through the presence or absence of the output of .

In addition, in the state where the malfunction is suppressed in the above manner, the user does not perform the process of releasing the touch of the starting point Z1 and touching again, but only maintaining the touch time of the starting point Z1. You can easily expand and preview a specific area to be enlarged by outputting it, and you can print it out.

Also, as described above, since the inner region Z21 and the outer region Z31 have a reduced shape of the terminal screen, when the inner region Z21 or the outer region Z31 is enlarged, it is enlarged as much as possible to match the shape of the terminal screen. Before the inner area Z21 or the outer area Z31 is enlarged, the user can determine in advance how far the specific part is included in the area to be enlarged (the inner area Z21 or the outer area Z31). There is an advantage that

That is, when the inner region Z21 is output, the part to be enlarged may not all be included in the inner region Z21, and the user can check this through the inner region Z21 in which the terminal shape is reduced. By making the touch of Z1) longer, the output of the outer region Z31 can be induced.

In addition, only by the operation of dragging from the first point to the in-between region and the dragging operation from the in-between region to the inner region Z21, the region to be output (inner region Z21 or outer region Z31) can be set. Since the outer region Z31 and the inner region Z21 are reduced regions on the screen of the terminal, the region between the terminals is formed along the perimeter of the terminal, and the starting point Z1 is farther away from the periphery of the terminal than the region between the regions. It has the advantage that it is possible to move to any convenient point among the regions in between, even while holding the terminal with one hand, so that it is possible to conveniently select an area to be output with one finger.

Through this, even if the outer dotted line Z3 is output by unintentionally touching the starting point Z1 for a longer period of time, it is possible to set the inner dotted line Z2 as an enlarged area without deleting the outer dotted line Z3. There is an advantage.

In addition, since the colors of the filling icons (the first filling icon Z22 and the second filling icon Z32) are semi-transparent colors, the specific part to be enlarged can be visually confirmed even after they are output.

In addition, since the filling icons enlarge the inner region Z21 or the outer region Z31 when the touch is released and the touch is re-touched, there is an advantage in that the enlargement of the selected region due to a malfunction can be suppressed.

The present invention described above with reference to the accompanying drawings is capable of various modifications and changes by those skilled in the art, and such modifications and changes not limited through the claims should be construed as being included in the scope of the present invention.
