Description

  The present invention relates to an entrance / exit management apparatus, an entrance / exit management method, and an entrance / exit management program for managing entrance / exit to / from a predetermined area.

  In a predetermined area where only a certifier with entry / exit authority can enter / exit, it is necessary to eliminate entry / exit to the predetermined area by an unauthenticated person without entry / exit authority for security reasons. In view of this, the entrance / exit is managed by checking whether or not the person who wishes to enter and leave the predetermined area is an authenticator.

  However, in recent years, entry and exit of unauthenticated persons due to sharing has become a problem. Co-payment means that an unauthenticated person enters and leaves a predetermined area following an authenticator.

  For example, there is a risk that an unauthenticated person who has entered a predetermined area due to sharing will acquire information existing in the predetermined area. On the other hand, when the date and time when a person in a predetermined area leaves is managed as a history, the leaving of an unauthenticated person due to a companion cannot be accumulated as a history.

  Therefore, in order to prevent companionship at entrance and exit, a flapper gate and a circle gate are installed. For example, it is a technique that allows a certifier to pass one by one by installing a flapper gate outside or inside a predetermined area.

  However, the installation of flapper gates and circle gates requires high equipment costs and large-scale construction. Therefore, it is not easy to introduce an entrance / exit management system using a flapper gate or a circle gate.

  Therefore, there is a technique for preventing an unauthenticated person from entering a predetermined area based on an image taken by a surveillance camera. The installation of the surveillance camera has an advantage that it is cheaper and easier than a flubber gate or a circle gate.

  For example, in Patent Document 1, the entrance / exit management device compares the number of persons permitted to enter by operating a card reader with the number of persons photographed by a monitoring camera that photographs the vicinity of the entrance. And when the number of people corresponds, the entrance / exit management apparatus discloses the technique of unlocking an electric lock.

  Moreover, in patent document 2, an entrance / exit management system detects an ID non-holding person who does not have an ID card. Then, the entrance / exit management system tracks non-ID holders around the entrance / exit by image processing. A technique is disclosed in which the entrance / exit management system does not unlock the door when it is detected that the non-ID holder has exceeded the reference line for determination of passage.

  Patent Literature 1 and Patent Literature 2 are technologies that do not permit the door to be opened when an unauthenticated person exists in the monitored area. In other words, as long as there is an unauthenticated person who happens to pass through the monitored area, opening the door is not permitted.

  If the monitored area is not an independent space, opening of the door may be unnecessarily hindered by detecting an unauthenticated person who passes through the monitored area. That is, the certifier who wishes to enter and leave cannot pass through the door indefinitely. Here, the independent space is, for example, an accumulating portion for authentication specially provided inside or outside a predetermined area.

  A case where the monitoring target area is not provided in an independent space will be described. For example, this is a case where a door provided in a predetermined area faces a corridor through which an unspecified person passes. In this case, entry / exit of a predetermined area is managed with a part of the corridor as an area to be monitored. In the techniques of Patent Document 1 and Patent Document 2, an unauthenticated person who only passes through the corridor is included in the monitored area, and the computer prohibits the door from being opened.

Therefore, when the area to be monitored cannot be set as an independent space as in the above example, entry and exit by the authenticator may be unnecessarily prevented in Patent Document 1 and Patent Document 2.
An object of the present invention is to provide an entrance / exit management apparatus, an entrance / exit management method, and an entrance / exit management program that help an efficient entry / exit by an authenticator.

In order to solve the above problems, an entrance / exit management device disclosed in the present invention is permitted to pass through a door of a tracking unit that tracks the movement of a monitoring target person existing in the monitoring target area and the monitoring target person. it will unauthenticated who is not Zui correspondence with the authentication information indicating the said tracking unit based on a result of tracking by the determination unit that determines a moving state within said monitored area, wherein the determining unit, the non If authenticator it is determined that away from the door, opening instructions with respect to the door opening and closing control device for controlling the opening and closing of the door, commands the opening of said door when the certifier is present in the monitored area And a command transmission unit for transmitting .

  According to the present invention, even if an unauthenticated person exists in the monitoring target area, the door can be opened based on the movement state of the unauthenticated person. Therefore, it is possible to prevent unauthorized entry / exit due to sharing, etc., and to prevent the door from being closed unnecessarily, thereby assisting the efficient entry / exit by the authenticator.

  Detailed examples of the present invention will be described below.

  FIG. 1 is a functional diagram of an entrance / exit management apparatus according to an embodiment of the present invention.

  When the door is open, entry / exit is permitted. On the other hand, when the door is closed, entry / exit is prohibited. It is good also as what manages entrance / exit not only according to this but the state of the unlocking | locking of the lock | rock provided in a door. That is, if the lock provided on the door is unlocked, entry / exit is permitted. On the other hand, if the lock is locked, entry / exit is prohibited.

  Here, the case where the opening / closing of a plurality of doors is controlled by one entrance / exit management device 1 will be described. However, the present invention is not limited to this, and one door control device 1 may control the opening and closing of one door.

  The entrance / exit management system includes an entrance / exit management device 1, one or more imaging devices 2, one or more authentication devices 3, and one or more opening / closing devices 4. Furthermore, the entrance / exit management device 1 and the imaging device 2, the entrance / exit management device 1 and the authentication device 3, and the entrance / exit management device 1 and the opening / closing device 4 are connected to each other in a communicable state. The communication line may be either a wireless line or a wired line.

  The entrance / exit management device 1 includes a communication unit 100, an analysis unit 11, a tracking unit 12, a determination unit 13, an area information database (hereinafter referred to as DB) 14, and a tracking information DB 15. The communication unit 100 is connected to a communication line. Further, the communication unit 100 includes functional units including an image reception unit 101, an authentication information reception unit 102, a door opening request reception unit 103, and a command transmission unit 104.

  The image receiving unit 101 is a processing unit that performs processing for receiving a captured image from the imaging device 2 connected via a communication line. The authentication information receiving unit 102 is a processing unit that performs a process of receiving authentication information from the authentication device 3 via a communication line. The authentication information is information including the content that the authentication of the unauthenticated person is successful. Further, the authentication information may include an authentication device ID for identifying the authentication device 3.

  The door opening request receiving unit 103 is a processing unit that performs a process of receiving a door opening request from the opening / closing device 4. The command output unit 103 is a processing unit that performs a process of outputting an opening / closing command related to opening / closing of the door 9 to the opening / closing device 4 connected via a communication line.

  The analysis unit 11 is a processing unit that analyzes the captured image received by the image reception unit 101 and extracts a monitoring target person existing in the monitoring target area. The tracking unit 12 is a processing unit that tracks the monitoring target person extracted by the analysis unit 11 and analyzes the movement of the unauthenticated person when the monitoring target person is an unauthenticated person. For example, the position coordinates are specified for each person to be monitored, or the distance from the unauthenticated person to the door is calculated.

  The determination unit 13 is a processing unit that determines how the unauthenticated person is moving with respect to the door based on the movement of the unauthenticated person analyzed by the tracking unit 12. Further, the determination unit 13 is also a processing unit that generates a door opening / closing command transmitted by the command transmission unit 103 based on the determination result.

  The movement state is information on how the unauthenticated person has moved within a predetermined time. For example, if the determination unit 13 determines that the distance to the door of the unauthenticated person is small, the command transmission unit 103 is caused to transmit a command to close the door.

  The area information DB 14 is a storage unit that stores information related to the monitoring target area. The tracking information DB 15 is a storage unit that stores information about the monitoring target person existing in the monitoring target area.

  FIG. 2 shows a supplementary diagram for explaining one embodiment of the present invention. FIG. 2 is a view of the vicinity of the monitoring target area as seen from above.

  A range between the wall 10A and the wall 10B is a corridor, a room, and the like, and a part thereof is extracted and shown in FIG. In addition, the passage of the door 9 from the area between the wall 10A and the wall 10B is managed. That is, only the authenticator can pass through the door 9 from the side sandwiched between the wall 10A and the wall 10B.

  A monitoring target area 81 is set on the side sandwiched between the wall 10A and the wall 10B. Here, a range corresponding to the coordinates P1, P2, P3, and P4 on the captured image by the imaging device 2 is set as the monitoring target area 81.

  The monitoring target area 81 may be arbitrarily set by the administrator. For example, in the monitoring target area 81, when an unauthenticated person who visually recognizes that the door is opened and tries to pass through the door, the unauthenticated person moves to the door 9 within the time required to close the door of the entrance / exit management system. It may be a range that cannot be reached.

  Persons 61, 62, 63, 64, and 65 that exist in the monitoring target area 81 are monitoring target persons. On the other hand, the person 7 existing outside the monitoring target area 81 is not a monitoring target person. Further, a monitoring target person whose passage authority of the door 9 is authenticated by the authentication device 3 is an authenticator, and an unauthenticated monitoring target person is an unauthenticated person.

  The entrance / exit management device 1 identifies an authenticator and an unauthenticated person based on information received from the imaging device 2 and the authentication device 3. Specific processing will be described later. In FIG. 2, the following description will be made assuming that the monitoring target persons 61 and 62 are authenticators and the monitoring target persons 63, 64 and 65 are unauthenticated persons.

  If there is no unauthenticated person in the monitoring area 81, the entrance / exit management device 1 commands the opening / closing device 4 to open the door 9. On the other hand, when there are unauthenticated persons 63, 64, 65 in the monitoring area 81 as shown in FIG. 2, the entrance / exit management device 1 opens and closes the door 9 based on the movement state of the unauthenticated persons 63, 64, 65. Is commanded to the switchgear 4.

  In addition to the monitoring target area 81, the monitoring required area 82 may be set as one example. A range corresponding to the coordinates P5, P6, P7, and P8 on the captured image by the imaging device 2 is set as a monitoring target area 82.

  For example, a range closer to the door 9 may be set as a monitoring required area. Then, the entrance / exit management device 1 may always close the door 9 when the unauthenticated person 65 is detected in the monitoring required area 82.

  By installing the monitoring required area 82, it is possible to prevent a risk that an unauthenticated person existing in a range where the passage of the door 9 is easier will pass through the door 9. Hereinafter, it is assumed that the setting and monitoring of the monitoring required area 82 can be applied to other embodiments.

  The imaging device 2 is a device that images the monitoring target area 81. The imaging device 2 is installed on a ceiling, a wall surface, or the like, for example, with the lens facing in the direction of the monitoring target area. Furthermore, a plurality of imaging devices 2 may be provided for one monitoring target area.

  In addition, the imaging device 2 captures the monitoring target area 81 at, for example, 30 frames per second, and transmits the captured image to the entrance / exit management device 1. Furthermore, the imaging device 2 may transmit an imaging device ID for identifying the imaging device 2 together with the captured image to the entrance / exit management device 1.

  Furthermore, the authentication device 3 is provided in the monitoring target area 81. The authentication device 3 is a device that performs an authentication process for an unauthenticated person who wants to pass through a door connecting a plurality of areas. The entrance / exit management device 1 detects that authentication by the authentication device 3 has been established, and recognizes an unauthenticated person as an authenticator.

  The authentication device 3 transmits authentication information to the entrance / exit management device 1 when the authentication is successful. The authentication method can be appropriately used from conventional techniques. The authentication device 3 determines the right to pass through the door based on the biometric information and password entered by the person who wants to enter or leave, or information read from a storage area of a portable storage medium such as an IC card carried by the person who enters or leaves. Authenticate.

  For example, the authentication device 3 refers to a DB that stores information related to a person who has the authority to pass through the door, and collates the input information or the read information. If the verification is successful, the authentication device 3 authenticates as an authenticator.

  The opening / closing device 4 is a device that controls the opening / closing of the door 9 based on a command from the entrance / exit management device 1. An opening / closing device 4 is connected to a door 9 provided at a boundary with a predetermined area. The opening / closing device 4 is a computer and includes an electric lock 41, a drive unit 42, and a door opening / closing control unit 43. Further, a human sensor for detecting a person existing near the door 9 may be provided. Moreover, the opening / closing device 4 may have some of these functional units.

  The electric lock 41 is a device that performs a lock function. The electric lock 41 is unlocked and locked by an electrical signal. For example, the electric lock 41 is brought into a locked state by projecting a dead bolt called a hook. That is, when the electric lock 41 is in a locked state with the door 9 closed, the opening of the door 9 can be prohibited.

  The drive unit 42 is a device that supplies power for opening and closing the door 9 by performing parallel movement and rotation of the door 9 when the door 9 is an automatic door. For example, the drive unit 42 is a motor. As the motor rotates, the door 9 moves and rotates.

  The door opening / closing control unit 43 is a functional unit that controls opening / closing of the door 9. That is, both or one of the electric lock 41 and the drive unit 42 is controlled based on a command from the entrance / exit management device 1.

  Subsequently, FIG. 3 will be used to describe the opening / closing control of the door 9 in more detail. FIG. 3 is a diagram showing the mechanism of the door 9 and the opening / closing device 4 in this embodiment. Moreover, FIG. 3 has shown the figure which looked at the door from the front. Here, the door 9 will be described as a sliding door type automatic door, but is not limited thereto. For example, the door 9 may be a hinged door having an electric lock 41.

  In FIG. 3, the door 9 is opened by horizontally moving in the direction 1 of the frame 95. Moreover, each door 9 moves horizontally in the direction 2 of 91 per door, and the door 9 will be in a closed state when the two doors 9 contact 91 per door. On the other hand, when the number of doors 9 is one, it will be in a closed state because one door 9 contacts the door.

  Based on a command from the entrance / exit control device 1, the door opening / closing control unit 43 drives the driving unit 421 in the direction of opening or closing the door 9, whereby the door 9 moves horizontally.

  Here, the drive unit 421 is a rotary motor 421. The rotation of the driven motor 421 is decelerated by a reduction gear (not shown) and transmitted to the belt 93. Since the door 9 is connected to the belt 93 via the suspension portion 92, the door 9 translates in a predetermined direction based on the operation of the belt 93. The moving range of the door is a range not exceeding the door pocket 94.

  Further, the rotation of the motor 421 is reversed when the door 9 is opened and closed. The door opening / closing control unit 43 opens and closes the door by controlling the driving and rotating direction of the motor 421 based on the command of the entrance / exit management device 1. Furthermore, by controlling the rotation speed of the motor 421, the door opening range can be limited.

  Here, the flow in which the door 9 opens in the present embodiment will be described. When a sensor (not shown) connected to the switchgear 4 detects an object or when a switch (not shown) is pressed by a person who wants to enter or leave, the switchgear 4 opens the door to the entrance / exit management device 1. Send release request information.

  Although details will be described later, the entrance / exit management device 1 performs processing described later when door opening request information is received. When the monitoring target person existing in the monitoring target area 81 satisfies a predetermined condition, the entrance / exit management device 1 outputs a door opening command to the opening / closing device 4. Then, the opening / closing device 4 opens the door 9 by the above-described method or the like based on the door opening command.

  Next, the flow of closing the door 9 in this embodiment will be described. There are cases of closing regardless of the control of the entrance / exit management device 1 and cases of closing based on a command from the entrance / exit management device. The former corresponds to, for example, a case where a sensor connected to the opening / closing device 4 no longer senses an object, or a case where a predetermined time has passed since opening. The latter corresponds to, for example, when the entrance / exit management device 1 outputs a door closing command to the opening / closing device 4 while the door is open. Details will be described later.

  Further, the door opening / closing control unit 43 transmits an electrical signal to the electric lock 41 based on a command to open or close the door 9 from the entrance / exit management device 1. The electric lock 41 is unlocked or locked. However, in the case of a door that does not have the electric lock 41, this process is not performed. When the door 9 is not an automatic door, the opening / closing device 4 controls the electric lock 41 without controlling the motor 421.

  Although the case where the door 9 is a sliding door was demonstrated, the case where the door 9 is a hinged door is demonstrated hereafter. The door 9 opens or closes when the door 9 rotates in an arc around a hinge (not shown) connecting the door 9 and an outer frame (not shown). A state where the door 9 is detached from the outer frame is an open state. On the other hand, the state in which the door 9 is housed in the outer frame is an open state.

  Further, the manager may provide the door 9 with an angle control device (not shown) that can control the opening range of the door 9. In this case, it is assumed that the opening / closing device 4 can also control the angle control device. Then, the angle control device limits the opening angle of the door 9 to limit the opening range of the door 9 and allow the door to be opened. Details of the restriction of the open range in the embodiment will be described later.

  An example of a data table stored in the area information DB 14 is shown in FIG. The area information DB 14 includes “monitoring area ID” 141, “monitoring area coordinates” 142, “door position coordinates” 143, “opening / closing device ID” 144, “opening / closing device address” 145, “imaging device ID” 146, “authentication” Information regarding each of “device ID” 147, “authentication device coordinates” 148, and “door open / closed state” 149 is stored in association with each other.

  The area information DB 14 may include a part of these items, and necessary items may be appropriately installed in the embodiment. In addition, FIG. 6 is used to explain the information stored in the area information DB 14. FIG. 6 is an overhead view in which two captured images at different times continuously received from the imaging device 2 are synthesized.

  The item “monitoring target area ID” 141 of the area information DB 14 is a data area for storing information for uniquely identifying the monitoring target area 81. For example, “A001” is stored.

  The item “monitoring target area coordinates” 142 in the area information DB 14 is a data area for storing the coordinates of each vertex forming the outline of the monitoring target area 81 on the captured image. A plurality of coordinates are stored depending on the shape of the monitoring target area 81. For example, in the case of a rectangular monitoring target area 81 as shown in FIG. 6, four vertices “P1, P2, P3, P4” are stored.

  It suffices if a specific position in the subject area can be specified on the image. When a plurality of imaging devices 2 are installed, the captured images received from the plurality of imaging devices 2 may be combined and specified as coordinates on the combined image. Moreover, although it demonstrates using a coordinate in order to pinpoint a position after that, it is not restricted to this.

  The item “door position coordinates” 143 of the area information DB 14 is a data area for storing coordinate data indicating the position of the door. For example, when the door 9 exists as shown in FIG. 6, the center point “(X9.Y9)” of the door is stored.

  The item “opening / closing device ID” 144 of the area information DB 14 is a data area for storing information for uniquely identifying the opening / closing device 4. That is, the information stored in the “opening / closing device ID” 144 specifies the opening / closing device 4 of the door 9 provided in the corresponding monitoring target area. For example, “B001” is stored.

  The item “opening / closing device address” 145 of the area information DB 14 is a data area for storing address information of communication means included in the opening / closing device 4. For example, the communication address “12.34.56.78” of the switchgear corresponding to the switchgear ID “B001” is stored.

  The item “imaging device ID” 146 in the area information DB 14 is a data area for storing information for uniquely identifying the imaging device 2. That is, the information stored in the “imaging device ID” 146 identifies the imaging device 2 that is capturing the corresponding monitoring target area. For example, when two imaging devices 2 are provided for one monitoring target area 81 as shown in FIG. 6, the imaging device IDs “C001, C002” are stored in association with the monitoring target area. .

  The item “authentication device ID” 147 of the area information DB 14 is a data area for storing information for uniquely identifying the authentication device 3. That is, the information stored in the “authentication device ID” 147 specifies the authentication device provided in the corresponding monitoring target area. For example, when two authentication devices 2 are provided as shown in FIG. 6, each authentication device ID “D001, D002” is stored.

  The item “authentication device coordinates” 148 of the area information DB 14 is a data area for storing data of center coordinates of the front surface of the authentication device 3. As shown in FIG. 6, the front surface 31 of the authentication device 3 is a surface of the authentication device 3 that faces the authentication device 3 in order for the unauthenticated person 60 to perform an authentication operation. And the center coordinate 32 is a coordinate of the center in the authentication apparatus 3 front when the authentication apparatus 3 is seen from the top like FIG. For example, the central coordinate “(X11, Y11)” of the front face of the authentication device 3 corresponding to the authentication device ID “D001” is stored.

  The item “door opening / closing status” 149 of the area information DB 14 is a data area for storing information on the opening / closing status of the door 9 that is controlled by the opening / closing device 4. For example, “0” is stored when the door 9 is closed, and “1” is stored when the door 9 is opened. When the entrance / exit management device 1 outputs a door opening command to the opening / closing device 4, “1” is stored in the door opening / closing status.

  On the other hand, when the entrance / exit management device 1 outputs a door closing command to the opening / closing device 4, or when the entrance / exit management device 1 detects that the door is closed regardless of the control of the entrance / exit management device 1, "0" Is stored.

  An example of a data table stored in the tracking information DB 15 is shown in FIG. The tracking information DB 15 includes “monitoring person ID” 151, “authentication status” 152, “previous coordinate” 153, “latest coordinate” 154, “previous distance” 155, “latest distance” 156, “number of times of movement” 157, “ Information relating to each of the “movement state flags” 148 is stored in association with each other.

  Further, each monitoring target person ID may be stored in association with the monitoring target area ID in which the monitoring target person corresponding to the monitoring target person ID is detected. FIG. 5 shows only information related to the monitoring target persons 61, 62, 63, 64, and 65 detected in the monitoring target area 81 corresponding to the monitoring target area ID “A001”.

  The tracking information DB 15 may include some of these items, and necessary items may be appropriately installed in the embodiment. Further, FIG. 6 is used as appropriate in order to explain the information stored in the tracking information DB 15. FIG. 6 is a conceptual diagram of the present embodiment, and schematically shows a state where the monitoring target area is viewed from above. It is assumed that the monitoring target persons 61 and 62 are authenticators and the monitoring target persons 63, 64 and 65 are unauthenticated persons.

  The item “monitoring person ID” 151 of the tracking information DB 15 is a data area for storing information for uniquely identifying the monitoring person. For example, “11111” is stored. Although details will be described later, each time a person is detected in the monitoring target area, a monitoring target person ID is uniquely assigned.

  Thereafter, in order to correspond to FIG. 6, the monitoring target person 61 is the monitoring target person ID “11111”, the monitoring target person 62 is the monitoring target person ID “22222”, the monitoring target person 63 is the monitoring target person ID “33333”, The monitoring target person 64 is set as a monitoring target person ID “44444”, and the monitoring target person 65 is set as a monitoring target person ID “55555”.

  Further, in FIG. 6, the latest image is shown as a monitoring target person 642 corresponding to the monitoring target person ID “44444”. Furthermore, in the photographed image received immediately before, it is shown in the same figure as the monitoring subject 641 corresponding to the monitoring subject ID “44444”.

  The item “authentication status” 152 of the tracking information DB 15 is a data area for storing information as to whether or not the monitoring subject has been authenticated by the authentication device 3. For example, “1” is stored for the authenticator and “0” is stored for the unauthenticated person. That is, an authenticator whose “authentication status” 152 stores “1” is permitted to pass through the door 9. On the other hand, unauthenticated persons whose “authentication status” 152 stores “0” are prohibited from passing through the door 9. In the initial state, “0” is stored.

  The item “previous coordinates” 153 of the tracking information DB 15 is a data area for storing coordinate data indicating the position of the monitoring subject in the previous captured image received by the image receiving unit 101. For example, as shown in FIG. 6, if the monitoring subject 641 exists in “(X4, Y4)” in the previous captured image, “(X4, Y4)” is stored. At this time, for example, central coordinates may be stored as coordinates for specifying the position of the person detected from the captured image.

  The item “latest coordinates” 154 of the tracking information DB 15 is a data area for storing coordinate data indicating the position of the monitoring subject in the latest photographed image received by the image receiving unit 101. For example, as shown in FIG. 6, when the monitoring target person 642 exists in “(X24, Y24)” in the latest photographed image, “(X24, Y24)” is stored.

  The item “previous distance” 155 of the tracking information DB 15 is a data area for storing distance information between the unauthenticated person and the door in the previous captured image received by the image receiving unit 101. For example, as shown in FIG. 6, when the unauthenticated person 64 exists in “(X4, Y4)” in the previous captured image, (X4, Y4) and the coordinates of the door (X9, Y9) The distance “10 (meters)” is stored.

  Here, the distance is not calculated for the authenticator and the “previous distance” 155 is blank, but the distance may be calculated for all the monitoring target persons.

  The item “latest distance” 156 of the tracking information DB 15 is a data area for storing distance information between the monitoring target person and the door 9 in the latest photographed image received by the image receiving unit 101. For example, as shown in FIG. 6, when the monitoring subject 64 is present at “(X24, Y24)” in the captured image received this time, (X24, Y24) and door coordinates (X9, Y9) Is stored as “8 meters”.

  The item “number of times of movement” 157 of the tracking information DB 15 is a data area for storing the number of times information in which the information stored in the previous distance 155 and the information stored in the latest distance 156 are the same. For example, in FIG. 6, the monitoring target person 65 has the previous distance “2 m” with respect to the position (X5, Y5) where the monitoring target person 65 is detected at the time of the previous captured image and the current entry / exit management. The latest distance “2 m” with respect to the position (X5, Y5) where the monitoring subject 65 is detected is the same. Accordingly, the number of times of movement is increased by 1, and the cumulative number of times “10” is stored.

  Here, it is determined that the distance coincides with the movement pear, but the present invention is not limited to this, and the number of movement pears may be counted based on the coordinate coincidence. Further, if the change in distance is equal to or smaller than a predetermined value, it is possible to determine that the monitoring subject is hardly moving and that the person is not moving.

  The item “movement state flag” 158 of the tracking information DB 15 is a data area for storing flag information regarding the movement state of the unauthenticated person. For example, when an unauthenticated person moves away from the door 9 during a predetermined time, the flag “0” is stored. Further, when an unauthenticated person moves closer to the door 9 during a predetermined time, a flag “1” is stored. Further, a flag “2” is stored when the unauthenticated person has not moved for a certain period of time. It is blank in the initial state.

  Since the unauthenticated person 63 in FIG. 6 is moving away from the door 9, the movement state flag “0” is stored. Since the unauthenticated person 64 is moving in the direction approaching the door 9, the movement state flag “1” is stored. Since the unauthenticated person 65 is not moving, the movement state flag “2” is stored.

  Next, movements related to the processing units shown in FIG. 1 of the entrance / exit management device 1 will be described with reference to FIGS. FIG. 7 is a processing flow for performing image analysis and monitoring of a monitoring target person.

  The image receiving unit 101 receives a captured image together with the imaging device ID from the imaging device 2 (S1). Then, the analysis unit 11 refers to the area information DB 14 and identifies the monitoring target area coordinates corresponding to the accepted imaging device ID. And the analysis part 11 detects the monitoring subject who exists in the monitoring target area based on the specified monitoring target area coordinate (S11). As a technique for extracting a person from an image, a conventional technique is used.

  The tracking unit 12 sequentially calls the detected monitoring target person and determines whether the monitoring target person can be specified (S12). That is, if it is not a monitoring target person who has newly entered the monitoring target area, it can be identified as the monitoring target person in the previous captured image.

  The process in which the tracking unit 12 specifies the monitoring target person identifies the monitoring target person extracted from the captured image between the captured images that are temporally continuous. A conventional technique may be used as a technique for identifying and tracking the person to be monitored. Specific examples are shown below, but are not limited thereto.

  The tracking unit 12 compares the previous photographed image with the latest photographed image, and specifies the portion having the highest correlation using the normalized correlation of the gray values. And based on this part, the monitoring subject who is judged to be the same as the monitoring subject of the latest photographed image in the previous photographed image is specified. The tracking unit 12 recognizes a monitoring target person that has not been correlated with the previously captured image as a new monitoring target person.

  When the tracking unit 12 cannot identify a monitoring target person and determines that the detected monitoring target person is a new monitoring target person (S12 NO), the tracking unit 12 assigns a monitoring target person ID to the new monitoring target person. To do. Then, the assigned monitoring target person ID is stored in the monitoring target person ID 151 of the tracking information DB 15 (S13). Further, the tracking unit 12 stores the coordinates of the monitoring subject in the latest photographed image in the latest coordinates 154 of the tracking information DB 15 in association with the monitoring subject ID (S14).

  Subsequently, the tracking unit 12 refers to the door opening state 149 of the area information DB 14 and determines whether “1” indicating that the door is open is stored (S15). Here, the tracking unit 12 refers to the area information DB 14 and refers to the door opening / closing state 149 corresponding to the monitored area ID being monitored.

  When “1” is stored in the door opening situation 149 of the area information DB 14 (S15 YES), the tracking unit 12 generates a door closing command for closing the door. The command output unit 104 transmits a door closing command to the opening / closing device address of the opening / closing device 4 of the door 9 (S16).

  That is, when the door is being opened, the entrance / exit management device 1 closes the door when a new unauthenticated person to be monitored is detected in the area to be monitored. By this mechanism, it is possible to prevent a newly detected monitoring target person from entering or leaving the monitoring target area.

  Here, in the case of closing the door based on the door closing command, it is not necessary to translate the door 9 until it contacts the door stop 91. In other words, there may be a state where there is a gap that does not allow people to pass. Furthermore, after the entrance / exit management device 1 detects that the unauthenticated person no longer exists in the monitoring target area, the opening device 4 may open the door 9 immediately.

  On the other hand, when “1” is not stored in the door opening situation 149 of the area information DB 14 (S16 NO), the process proceeds to S17. The tracking unit 12 calculates the distance between the unauthenticated person to be monitored and the door based on the latest coordinates 154 in the tracking information DB 15 and the door position coordinates 143 in the area information DB 14. Then, the tracking unit 12 stores the calculated distance in the latest distance 156 of the tracking information 15 (S17). Then, the process proceeds to S23.

  When the tracking unit 12 can identify the monitoring subject (S12 YES), the tracking unit 12 stores the coordinate of the monitoring target in the latest image as the latest coordinate in the latest coordinate 154 of the tracking information DB 15 (S18). At that time, the coordinates stored in the latest coordinates 154 of the tracking information DB 15 at the start of the image analysis / tracking process are stored in the previous coordinates 153. Then, the process proceeds to S19.

  In the case of using the technique exemplified in S12, the tracking unit 12 calculates the coordinates in the previous captured image of the monitoring subject identified as being identical between the two captured images. Then, the tracking unit 12 refers to the tracking information DB 15 and identifies a monitoring target person ID having the latest coordinates of the monitoring target person in the previous captured image. The tracking unit 12 stores the coordinate data initially stored in the latest coordinates 154 in the previous coordinates 153 in association with the identified monitoring subject ID. Further, the tracking unit 12 newly stores the coordinates of the monitoring target person in the latest photographed image in the latest coordinates 153.

  Subsequently, the tracking unit 12 refers to the authentication status 152 of the tracking information DB 15 and determines whether “1” indicating that the monitoring subject is authenticated is stored (S19). If “1” is stored in the authentication status 152 of the tracking information DB 15 (S19 YES), the process proceeds to S23.

  On the other hand, if “1” is not stored in the authentication status 152 of the tracking information DB 15 (S19 NO), the tracking unit 12 has not yet performed based on the latest coordinates 154 of the tracking information DB 15 and the door position coordinates 143 of the area information DB 14. The distance between the certifier and the door is calculated. Then, the tracking unit 12 stores the calculated distance in the latest distance 156 of the tracking information 15 (S20). At that time, the tracking unit 12 stores the data stored at the latest distance 156 in the previous distance 155 in the tracking information DB 15 at the start of the image analysis / tracking process.

  Subsequently, the tracking unit 12 refers to the tracking information DB 15 and determines whether or not the latest distance 156 and the previous distance 155 are the same (S21). Although it is the same here, it may be considered that it is the same as long as it moves within a predetermined range.

  When the latest distance 156 and the previous distance 155 are the same (S21 YES), the tracking unit 12 increments the number of movement pears in the tracking information DB 15 by 1 (S22). On the other hand, if the latest distance 156 and the previous distance 155 are not the same (NO in S21), the process proceeds to S23.

  If the answer is NO in S21, the tracking unit 12 may delete the information stored in the number of times of movement 157. If not deleted, an unauthenticated person who has stopped many times in the monitored area can be tracked.

  Subsequently, the tracking unit 12 determines whether or not the tracking process for all the monitoring target persons detected in the monitoring target area has been completed. If it is determined that the tracking unit 12 has not ended (NO in S23), the process returns to S12. On the other hand, when it is determined that the tracking unit 12 has ended (S23 YES), the processing ends.

  Here, this processing is performed every time images taken continuously are received. However, only the process for tracking the monitoring target person may be performed, and the distance calculation may be performed once for reception of a plurality of images.

  Hereinafter, FIG. The flowchart of the image analysis / tracking process of FIG. 7 will be described with reference to FIGS. Here, entry / exit in the monitoring target area corresponding to the monitoring target area ID “A001” in FIG. 4 is managed, and the monitoring target person 642 (FIG. 6) corresponding to the monitoring target person ID “44444” in FIG. 5 is tracked. It shall be.

  In FIG. 6, the monitoring target person 642 corresponding to the monitoring target person ID “44444” in the latest image is shown. In the previous photographed image that was accepted one time ago, the monitoring subject ID “44444” is shown as the monitoring subject 641 in the same figure.

  The image receiving unit 101 receives a captured image together with the imaging device ID “C001” from the imaging device 2 (S10). Then, the analysis unit 11 refers to the area information DB 14 and identifies the monitoring target area coordinates “P1, P2, P3, P4” corresponding to the received imaging device ID “C001”. And the analysis part 11 detects the monitoring subject "61, 62, 632, 642, 65" which exists in the monitoring target area based on the specified monitoring target area coordinate (S11).

  The tracking unit 12 determines that the detected monitoring target person 642 is not a new monitoring target person (NO in S12). Then, the tracking unit 12 specifies that the detected monitoring target person is the monitoring target person ID “44444”. Further, the tracking unit 12 stores the coordinates (X24, Y24) of the monitoring target person 642 in the latest image as the latest coordinates in the latest coordinates 154 of the tracking information DB 15 (S18).

  Then, at the start of the image analysis / tracking process (corresponding to the monitoring subject 641 in FIG. 6), the coordinates (X4, Y4) stored in the latest coordinates 154 of the tracking information DB 15 are stored in the previous coordinates 153.

  Subsequently, the tracking unit 12 refers to the tracking information DB 15 and determines that “1” is not stored in the authentication status 152 corresponding to the monitoring subject ID “44444” (NO in S19). Then, the tracking unit 12 calculates the distance “8 m” between the monitoring subject 642 and the door 9 based on the latest coordinates 154 (X24, Y24) of the tracking information DB 15 and the door position coordinates 143 (X9, Y9) of the area information DB 14. Calculate (S20).

  Further, the tracking unit 12 stores the calculated distance in the latest distance 156 of the tracking information DB 15. At that time, the data “10 m” stored in the latest distance 156 in the tracking information DB 15 at the start of the image analysis / tracking process is stored in the previous distance 155.

  Subsequently, the tracking unit 12 refers to the tracking information DB 15 and determines that the latest distance 156 “8 m” and the previous distance 155 “10 m” are not the same (NO in S21). Subsequently, the tracking unit 12 determines whether or not the tracking process for all the monitoring target persons detected in the monitoring target area has ended (S23).

  Next, a process for changing the authentication status will be described. FIG. 8 is a processing flow for changing the authentication status.

  The authentication device 3 performs an authentication process on an unauthenticated person who wishes to pass through the door 9 (S31). The authentication process uses a conventional method. If the authentication is successful, the authentication device 3 transmits authentication information to the entrance / exit management device 1 (S32). The authentication information includes the authentication device ID of the own device and information indicating that the authentication has been established.

  The authentication information receiving unit 102 of the entrance / exit management device 1 receives the authentication information (S33). Then, the analysis unit 11 analyzes the latest photographed image, and the tracking unit 12 specifies the authenticated monitoring subject ID (S34). Subsequently, the tracking unit 12 refers to the tracking information DB 15 and changes the authentication status corresponding to the identified monitoring target person ID to information “1” indicating that the authentication has been completed. And it ends.

  Hereinafter, the authentication status change process in the entrance / exit management device 1 will be described with reference to FIGS. 4, 5, and 6 exemplarily. Based on the authentication device ID “D001” included in the authentication information, the central coordinates are read from the area information DB. Then, when the tracking unit 12 receives the authentication information, the tracking unit 12 specifies the coordinates (X1, Y1) of the monitoring subject that is closest to the center coordinates 32 (X11, Y11) of the authentication device 3.

  Then, the tracking unit 12 refers to the tracking information DB 15 and specifies the monitoring target person ID “11111” having the coordinates (X1, Y1) of the monitoring target person 61 as the latest coordinates 156. Then, the tracking unit 12 rewrites the authentication status 152 corresponding to the monitoring target person ID “11111” from “0” indicating unauthenticated to “1” indicating that authentication is established.

  Further, the authentication process is not limited to the above technique, and it is only necessary to be able to grasp the authentication status and the position in association with each other. For example, it is assumed that the person to be monitored holds an IC card lent only to an authenticator. Then, the reader device reads the electronic tag built in the IC card and specifies the position of the electronic tag. Then, it is managed in association with the coordinate position on the captured image. That is, a technique for tracking the position of the IC card as the position of the authenticator as it is can be applied.

  Next, processing for managing entry / exit will be described. FIG. 9 is an entrance / exit management processing flow. The door opening request receiving unit 103 receives a door opening request from the opening / closing device 4 (S1). The door opening request is an instruction for starting an entrance / exit management process, and is information including an opening / closing device ID for identifying the transmitted opening / closing device 4.

  That is, when a sensor (not shown) connected to the opening / closing device 4 detects an object, or when a switch (not shown) is pressed by a person who wants to pass through the door, the opening / closing device 4 makes a door opening request. Generate. Then, the opening / closing device 4 transmits the door opening request reception unit 103 of the entrance / exit management device 1. Thereby, the entrance / exit management process is started. Further, while the door is open, the following processing may be continuously executed.

  Next, the determination unit 13 refers to the tracking information DB 15 to determine whether or not an unauthenticated person exists in the monitoring target area (S2). When an unauthenticated person exists (S2YES), the determination part 13 performs a movement state determination (S4).

  On the other hand, when there is no unauthenticated person (S2NO), the command transmission part 104 transmits a 1st door opening command with respect to the opening / closing apparatus 4 which transmitted the said door opening request (S3). Further, the determination unit 13 changes the door opening state 149 of the area information DB 14 to “1” which is information indicating that the door is open. Here, the first door opening command is a command for opening the door without limiting the door opening range.

  If YES in S2, the process proceeds to S4. As the details of S4, the process flow of the movement state determination process will be described with reference to FIG. First, the determination unit 13 sequentially detects a monitoring target person who stores “0” indicating that the authentication status 152 is not authenticated from the tracking information DB 15 (S401). And the determination part 13 acquires the information of the newest distance stored in the newest distance 154 of tracking information DB15 (S402).

  Further, the determination unit 13 determines whether or not information related to the previous distance is stored in the previous distance 155 (S403). When the information regarding the previous distance is not stored (S403 NO), the determination unit 13 stores “1” in the movement state flag 158 of the tracking information DB 15 (S405).

  An unauthenticated person having the movement state flag “1” indicates a movement state approaching the door. Therefore, this unauthenticated person may recognize that the authenticator is trying to open the door and move toward the door. That is, such an unauthenticated person should not open the door because there is a risk of passing the door at the moment when the door is opened.

  If the determination unit 13 determines NO in S403, the unauthenticated person detected in S401 is an unauthenticated person who has newly entered the monitoring target area with the latest image. Therefore, for the new unauthenticated person, information for determining the movement state is lacking.

  Therefore, in order to ensure security, “1” indicating that the movement state of the unauthenticated person is moving toward the door is stored. However, if more importance is placed on the efficiency of entry / exit of the certifier, another flag may be set.

  On the other hand, when information on the previous distance is stored (YES in S403), the determination unit 13 compares the previous distance with the latest distance (S404). When the latest distance is smaller than the previous distance (S404 previous distance> latest distance), the determination unit 13 stores “1” in the movement state flag 158 of the tracking information DB 15 (S405). That is, it is determined that the movement state of the unauthenticated person is movement in a direction approaching the door. Then, the process proceeds to S409.

  Next, when the latest distance is larger than the previous distance (S404 previous distance <current distance), the determination unit 13 stores “0” in the movement state flag 158 of the tracking information DB 15 (S406). That is, it is determined that the movement state of the unauthenticated person is movement in a direction away from the door. Then, the process proceeds to S409.

  Next, when the latest distance is equal to the previous distance (S404 previous distance = latest distance), the determination unit 13 refers to the number of times of movement 157 in the tracking information DB 15. And the determination part 13 determines whether the number of movement pears is more than a threshold value (S407). When the number of times of movement is greater than or equal to the threshold (YES in S407), the determination unit 13 stores “2” in the movement state flag 158 (S406). That is, it is determined that the movement state of the unauthenticated person is not moving. Then, the process proceeds to S409.

  Here, the unauthenticated person who has not moved is stopped and waiting for the door to be opened by the authenticator, and there is a risk of passing through the door at the moment when the door is opened. Therefore, when such a movement state is detected, the door should not be opened.

  Therefore, a threshold is used to determine how long it should be determined that there is a risk when unauthenticated persons who have not moved are continuously detected. The administrator who operates this system sets a threshold value in advance, and specifies an unauthenticated person who has not moved beyond the threshold value.

  On the other hand, when the number of times of movement is less than or equal to the threshold (NO in S407), the determination unit 13 stores “0” in the movement state flag 158 of the tracking information DB 15 (S406). By doing so, it is possible to improve the efficiency of entry / exit of the authenticator.

  However, when the previous distance is equal to the latest distance (S404 previous distance = latest distance), the determination unit 13 may store “2” in the movement state flag 158 without comparing with the threshold value. In this way, security can be further ensured.

  And the determination part 13 determines whether the movement state determination with respect to all the unauthenticated persons was performed (S409). In other words, in the tracking information DB 15, it is determined whether there is a monitoring target person whose movement state flag 158 is blank among monitoring target persons whose authentication status 152 stores “0”. When the movement state determination for all unauthenticated persons has not been executed (NO in S409), the determination unit 13 returns to S401, and reads undetermined unauthenticated persons.

  On the other hand, when the movement state determination for all unauthenticated persons is executed (YES in S409), the determination unit 13 determines whether the movement state flag of all unauthenticated persons is “0” (S410).

  If the movement status flags of all unauthenticated persons are not “0” (NO in S410), the command transmission unit 104 transmits a door closing command to the opening / closing device 4 that has transmitted the door opening request (S411). That is, since an unauthenticated person in a moving state that may be aiming to pass through the door is detected, the entrance / exit management device 1 does not permit the door to be opened. And it ends.

  When the movement status flag of all unauthenticated persons is “0” (S410 YES), the command transmission unit 104 transmits a second door opening command to the opening / closing device 4 that has transmitted the door opening request (S412), finish. Here, the second door opening command may be a command similar to the above-described first door opening command. Further, the second door opening command may be a content that limits the opening range of the door and opens the door.

  As a control for limiting the opening range of the door, for example, in FIG. 3, the door 9 can be translated (direction 1) to the extent that one person can pass under the control of the opening / closing device 4. Or, if it is a hinged door, the opening angle may be limited and the door may be opened.

  By doing in this way, even if it is one person at a time, since the authenticator can pass through the door, it is possible to prevent the authenticator from staying near the door. Furthermore, since the open range is limited, the door can be closed in a short time when an unauthenticated person with the movement state flag “1” or “2” is detected.

  This is because the motor 421 of the automatic door can be in an idling state while the half-open state is maintained. Therefore, the motor startup time can be reduced when the half-open door is fully opened or closed to the extent that it cannot pass. Furthermore, the moving distance of the door can be shorter than when the door is fully opened from the fully opened state.

  Hereinafter, FIG. The flowchart of the entrance / exit management process and the movement state determination process of FIGS. 9 and 10 will be described with reference to FIGS. 5 and 6. Here, it is assumed that entry / exit from the monitoring area corresponding to the monitoring target area ID “A001” in FIG. 4 is managed.

  The door opening request receiving unit 103 receives a door opening request including the opening / closing device ID “B001” from the opening / closing device 4 (S1). The determination unit 13 refers to the tracking information DB 15 and determines whether or not an unauthenticated person exists in the monitoring target area (S2). Since there is an unauthenticated person (monitored person IDs “33333”, “44444”, “55555”) (S2 YES), the determination unit 13 determines the movement state (S4).

  Turning to FIG. 10, it is assumed that the movement state of the monitoring target person 642 (FIG. 6) corresponding to the monitoring target person ID “44444” in FIG. 5 is determined. The determination unit 12 detects a monitoring target person (monitoring target person ID “44444”) storing “0” indicating that the authentication status 152 is not authenticated from the tracking information DB 15 (S401). Then, the determination unit 13 acquires the latest distance “8 m” stored in the latest distance 154 of the tracking information DB 15 (S402).

  Furthermore, since the previous distance “10 m” is stored (YES in S403), the determination unit 13 compares the previous distance “10 m” with the latest distance “8 m” (S404). Since the latest distance “8 m” is smaller than the previous distance “10 m” (S404, previous distance> latest distance), the determination unit 13 stores “1” in the movement state flag 158 of the tracking information DB 15 (S405). And the determination part 13 determines whether the movement state determination with respect to all the unauthenticated persons was performed (S409).

  Here, it is assumed that the movement state flag “0” is stored in association with the monitoring subject ID “33333” and the movement state flag “2” is stored in association with the monitoring subject ID “55555”.

  Since the movement state determination for all unauthenticated persons has been executed (YES in S409), the determination unit 13 determines that there is an unauthenticated person whose movement state flag is not “0” (NO in S410). The command transmission unit 104 transmits a door closing command to the opening / closing device 4 (opening / closing device ID “B001”) that has transmitted the door opening request (S411).

  In the present embodiment, the moving state of the monitoring subject is determined using the distance between the monitoring subject and the door at a predetermined time, but the present invention is not limited to this. For example, it is sufficient if the determination unit 13 can determine the movement state of the monitoring target person with respect to the door by calculating a direction vector.

  With the configuration described above, entry / exit can be managed while helping an efficient entry / exit by the certifier and further ensuring security. That is, even if an unauthenticated person exists in the monitoring target area, the door is permitted to be opened based on the movement state of the unauthenticated person. Therefore, waiting time by the authenticator can be reduced, and entrance / exit can be made efficient.

  Furthermore, the present embodiment requires a small amount of equipment and construction costs compared to entrance / exit management with a flapper gate and a circle gate.

  Next, a second embodiment will be described with reference to FIG. In FIG. 11, it is assumed that the authenticator 67 exists in the monitoring target area 812 (monitoring target area ID “A003”) and desires to leave the monitoring target area 812. At this time, in the second embodiment, the state of the monitoring target area 811 on the opposite side across the door 9 (monitoring target area ID “A001”) is determined. And the opening and closing of the door 9 is controlled based on the determination result of both the monitoring target areas.

  FIG. 12 is an entrance / exit management processing flow in this embodiment. The associated movement of each processing unit in the present embodiment will be described with reference to FIG.

  The door opening request receiving unit 104 receives a door opening request from the opening / closing device 4 (S90). The door opening request includes an opening device ID for identifying the opening device 4 and information indicating from which monitoring target area the door opening request is made. And the entrance / exit management apparatus 1 performs the 1st entrance / exit management of the 1st monitoring object area where the monitoring subject who desires entrance / exit exists. Since the processing contents are the same as those in FIGS. 9 and 10, they are omitted.

  Then, as a result of the first entrance / exit management, when it is determined that the door opening is not permitted in the first monitoring target area (NO in S91), the command transmitting unit 104 transmits a door closing command to the opening / closing device 4. (S92). On the other hand, as a result of the first entrance / exit management, when it is determined that the door opening is permitted in the first monitoring target area (YES in S91), the determination unit 13 further performs the second entrance / exit in the second monitoring target area. Perform management.

  At this time, the determination unit 13 reads the monitoring target area coordinates in the area information DB 14 in which the same opening / closing device ID is stored in the opening / closing device ID 144. In this way, the determination unit 13 identifies the monitoring target area existing on the opposite side of the door as the second monitoring area.

  Then, as a result of the second entrance / exit management, when it is determined that the door opening is not permitted in the second monitoring target area (NO in S93), the command transmitting unit 104 transmits a door closing command to the opening / closing device 4. (S92). As a result of the second entrance / exit management, when it is determined that the door opening is permitted in the second monitoring target area (YES in S93), the command transmission unit 104 transmits a door opening command to the switchgear 4 (S94). ).

  At this time, the content of the door opening command may limit the door opening range based on the results of the first entry / exit management and the second entry / exit management.

  Hereinafter, an example will be described with reference to FIG. For example, the door opening request receiving unit 104 receives a door opening request from the opening / closing device 4 “B001” (S90). The door opening request includes information indicating that the door opening request is from the monitoring target area 812 having the opening device ID “B001” for identifying the opening device 4 and the monitoring target area ID “A003”.

  Then, the entrance / exit management device 1 performs first entrance / exit management of the first monitoring target area 812 where the monitoring target person who desires to enter / exit exists. As shown in FIG. 11, it is assumed that only the monitoring target person 67 exists in the monitoring target area 812, and the monitoring target person 67 has been authenticated.

  Therefore, as a result of the first entrance / exit management, the determination unit 13 determines to permit door opening in the first monitoring target area (YES in S91). Subsequently, the determination unit 13 further performs second entrance / exit management in the second monitoring target area 811 installed on the opposite side across the door from the first monitoring target area.

  At this time, in the area information DB 14, the monitoring target area coordinates (P 1, P 2, P 3, P 4) of the monitoring target area ID “A001” in which the same switching apparatus ID “B001” is stored in the switching apparatus ID 144 are read. In this way, the monitoring target area 811 existing on the opposite side of the door is specified.

  As a result of the second entrance / exit management, the monitoring target person 68 and the monitoring target person 69 are detected in the second monitoring target area 811. Here, it is assumed that the monitoring target person 68 and the monitoring target person 69 are both unauthenticated persons. Further, assuming that the monitoring subject 68 is moving in a direction approaching the door 9, the determination unit 13 determines that the door opening is not permitted (NO in S93). Then, the command transmitting unit 104 transmits a door closing command to the opening / closing device 4 (S92).

  Further, in FIG. 1, it is described that any area is monitored as a monitoring target area for entrance / exit management. However, the entrance / exit management device 1 may execute the entrance / exit management process shown in FIG. 12 only when it is desired to enter / exit from one of the monitoring target areas. For example, when a door opening request is received from an area with a high security level, passage of an unauthenticated person's door in an area with a low security level can be prevented.

  With the above configuration, unauthorized entry / exit by an unauthenticated person can be prevented more reliably. For example, it is assumed that an unauthenticated person existing in the monitoring target area 811 waits for the door to be opened to enter the monitoring target area 812 side. In this embodiment, when an authenticator existing in the monitoring target area 812 wishes to enter / exit, entrance / exit management is also performed for the monitoring target area 811 on the other side of the door. Therefore, entry / exit by an unauthenticated person with malicious intent can be prevented more reliably.

  Further, in the present embodiment, an example in which a person is detected from an image has been described. However, any method that can detect the movement state of a person can be used as an alternative. For example, by laying a pressure sensor on the entire floor of the monitoring target area, it is possible to identify a person and to detect a moving state.

  Therefore, a pressure sensor is provided instead of the imaging device 2, and the image receiving unit 101 receives information from the pressure sensor. The tracking unit 12 may store the position coordinates of the pressure sensor that has detected the pressure in association with the monitoring subject ID. The subsequent entrance / exit management process is the same as the process described above, and is therefore omitted.

  The embodiment of the present invention is not limited to the above.

  Hereinafter, a computer that executes an entrance / exit management program having the same function as the entrance / exit management device 1 and the entrance / exit management device 1 described in the above embodiment will be described as an example with reference to FIG. FIG. 13 is a diagram illustrating an example of a hardware configuration of the entrance / exit management device 1. The entrance / exit management device 1 includes a CPU 1001, a ROM 1002, a RAM 1003, a communication unit 1004, an HDD 1005, an input unit 1006, a medium reading unit 1007, and a display unit 1008, and these units are connected to each other via a bus 1009. Data can be transmitted and received with each other under the control of the CPU 1001.

  The CPU 1001 is a central processing unit that controls the operation of the entire entrance / exit management device 1. The communication unit 1004 receives a signal from the outside and passes the content of the signal to the CPU 1001. Further, the communication unit 1004 transmits a signal to the outside in response to an instruction from the CPU 1001.

  The HDD 1005 stores at least a program for causing the computer to execute each process of FIG. 10 as a program for causing the computer to perform the same function as the entrance / exit management device 1 shown in the above-described embodiment.

  The CPU 1001 reads out and executes this program from the HDD 1005, thereby functioning as the analysis unit 11, the tracking unit 12, and the determination unit 13 illustrated in FIG. This program may be stored in the ROM 1002 or the RAM 1003 accessible to the CPU 1001.

  Further, the HDD 1005 stores an area information DB 14 and a tracking information DB 15 shown in FIG. Like the program, these DBs may be stored in the ROM 1002 or the RAM 1003 accessible to the CPU 1001. The input unit 1006 receives data input under the control of the CPU 1001.

  The program describing the processing content shown in the flowchart can be recorded on a computer-readable recording medium. Examples of the computer-readable recording medium include a magnetic recording device, an optical disk, a magneto-optical recording medium, and a semiconductor memory. Examples of the magnetic recording device include an HDD, a flexible disk (FD), and a magnetic tape (MT).

  Examples of the optical disc include a DVD (Digital Versatile Disc), a DVD-RAM, a CD-ROM (Compact Disc-Read Only Memory), and a CD-R (Recordable) / RW (ReWriteable). Magneto-optical recording media include MO (Magneto-Optical disk). When this program is distributed, for example, a portable recording medium such as a DVD or CD-ROM in which the program is recorded may be sold.

  In the computer that executes the program, for example, the medium reading unit 1007 reads the program from a recording medium that records the program describing the processing contents shown in the flowchart. The CPU 1001 stores the read program in the HDD 1005, the ROM 1002, or the RAM 1003. Then, the computer reads the program from the HDD 1005, the ROM 1002, or the RAM 1003, which is its own storage device, and executes processing according to the program.
