[0003]

However, for example,
In facilities such as condominiums and condominiums where multiple rooms are grouped together, a person who is allowed to access only a part of the facility once enters the facility from the common entrance of the entire facility. Thus, there is a problem that it becomes possible to access a room to which access is not permitted, and it is possible to try to access even if access is not possible.

[0004] For example, once an apartment has been entered into a multi-family residence by permission from the inside, it is possible to visit a room other than the permitted room, or to a room where no one is inside. It was possible to find and unlock the doors illegally.

[0005] Therefore, the present invention manages entry without sacrificing security, even when a person who is not normally permitted to enter a facility or room, such as a visitor, is temporarily permitted to enter. And by prohibiting access to places other than those where entry is permitted, thereby minimizing the influence on persons who are not directly related to the person. The purpose is to provide.

Further, the present invention automatically detects that a person who is temporarily permitted to enter a part of a plurality of rooms has access to a place other than a previously permitted place. It is another object of the present invention to provide an entrance management apparatus and an entrance management method for preventing entry permission for the person.

In addition, the present invention performs face authentication not only when entering a room but also when exiting a room, and by storing the result, it is possible to perform appropriate face authentication according to specific room presence / absence information. It is an object to provide an entrance management device and an entrance management method capable of performing access management.

Further, in the present invention, in which a door is unlocked by face authentication, a daily authentication history is held so that the authentication history can be browsed at any time and the number of authorized persons grows. It is an object of the present invention to provide an entrance management device and an entrance management method that can automatically create a record, a diary, and the like.

It is installed in the room 3 and sends a door unlock signal to the door control devices 17 and 27 as needed by the operation of a person in the room 3.

Hereinafter, each part will be described in detail.

First, each unit of the reception server 4 will be described.

The camera 11 is composed of, for example, an ITV camera, and shoots a face image of a person standing in front of the door 2a of the common entrance 2, and the shot face image is A / D converted. Thereafter, the image data is stored in an image memory provided in the face area detection unit 31.

The number of cameras 11 is not particularly limited, and may be one instead of a plurality. Further, by using a camera having a pan / tilt / zoom function in addition to a fixed camera, a wider range is provided. It is also possible to input an image of the area or to increase the resolution of the attention area by zooming. When a plurality of cameras are used, the processing up to the similarity determination unit 33 described below is repeated for the input image in the image memory captured by each camera.

The face area detecting section 31 moves the template image data of an average face prepared in advance on the input image input by the camera 11 and stored in the image memory while moving the template image data on the input image data. ,
The face area is detected by setting the position giving the highest correlation value as the face area.

In addition to the method of evaluating the correlation value with the template image data, a method of evaluating the similarity with the template image of the face using the subspace method can be also realized. Depending on the detection result of the face area, not only one face area but a plurality of face areas will be detected. In this case, the processing up to the similarity determination unit 33 described below will be repeated.

The face feature extraction unit 32 first detects face parts such as eyes, nose, and mouth from the face area detected by the face area detection unit 31. The detection method is described, for example, in the literature (Kazuhiro Fukui, Osamu Yamaguchi: "Face feature point extraction by combination of shape extraction and pattern matching", IEICE Transactions (D),
vol. J80-D-II, No. 8, pp2170-
2177 (1997)).

Next, based on the detected position data of each part, the previously detected face area is cut out to a fixed size and shape, and the inclination and size are corrected to form an area of m × n pixels. Created, and m × n-dimensional information is used as a face feature vector.

Here, information such as the fact that face parts such as eyes and nose are difficult to detect and face areas can be easily detected if the face direction is different from the current one,
In the case where the detection has been made but there is no fluctuation as in a photograph or the like, a guidance message “Please turn in a predetermined direction” can be output from the output device 12.

The registration information holding device 16 holds a face feature amount used for identifying a person. For the feature amount of a face used to identify a person, data obtained by accumulating images obtained through the camera 11 and the face area detection unit 31 in time series is prepared, and a known KL is used for the data. By calculating an orthonormal vector by expansion, a subspace is calculated together with the dictionary.

It is also possible to prepare a plurality of dictionary data (feature values) for one person. It is also possible to prepare the dictionary data (feature amount) and to determine that the collation has been successful if any of the dictionary data can be identified.

The storage medium in the registration information holding device 16 may be any storage medium such as a silicon disk, an optical disk, or a hard disk as long as it can store digital information. The registration information holding device 16 of the reception server 4 is a server viewed from the registration information holding device 26 of the room terminal device 5, and a person who is temporarily permitted to enter (hereinafter referred to as a “visitor”) comes and is newly registered. When the face information is registered, the face information is broadcast to each room terminal device 5 so that each room terminal device 5 can identify the face of the visitor.

The similarity judgment section 33 will be described. The similarity determination (person recognition) method in the present embodiment is described in, for example, literatures (Kenichi Maeda, Seiichi Watanabe: "Pattern matching method introducing local structure", IEICE Transactions (D), vol. J68-D, No. 3, pp345-
352 (1985)) and the mutual subspace method in "person authentication apparatus and method" disclosed in Japanese Patent Application Laid-Open No. 9-251534, but other pattern recognition methods may be used as the recognition method. Absent.

The similarity determination unit 33 includes a face feature extraction unit 32
Is obtained by accumulating a certain number of feature values obtained in the time series in a time series, obtaining an orthonormal vector by KL expansion for the data, calculating a subspace, and storing a dictionary held in the registration information holding device 16 in advance. Compared with the data (reference feature amount), if the similarity has the highest value and is higher than a predetermined threshold, it is determined that the person corresponds to the registered dictionary that gives the similarity. When the highest similarity does not exceed the predetermined threshold, the person who is allowed to enter the building 1 in advance (hereinafter referred to as “registrant”) is temporarily allowed to enter. Is determined to be a visitor.

Output device (LCD monitor 12, speaker 1
3) feeds back the detection result of the face to the person to be authenticated, gives guidance such as the start of authentication, and displays the authentication result and outputs guidance voice (see FIG. 6A). As the display means, in addition to the liquid crystal monitor, a normal C
Any device capable of displaying images and characters, such as an RT display, may be used, and the input means according to the display content may be realized by a liquid crystal monitor with a touch panel, or by separately providing a numeric keypad. Further, a method of outputting a mark using a speaker, an LED, or a lamp as an audio output unit is also conceivable.

When it is determined that the user is a “visitor” in the authentication result up to the similarity determination, a screen for inputting information (room number) indicating the target room as shown in FIG. Is displayed, the information is input, the visitor's face image is transferred to the room terminal device 5 corresponding to the destination, and a notification screen as shown in FIG. 6C is displayed on the liquid crystal monitor 22b. And informs that a visitor is coming.

In the destination place input screen of FIG. 6B, 51 is a photographed face image of the visitor, 52 is an operation button for inputting a room number and the like, and 53 is a display section of the input room number. Is shown. In the room notification screen of FIG. 6C, reference numeral 54 denotes a visitor's face registration image, 55 denotes an admission permission button, 56 denotes an entrance validity period setting button, and 57
Indicates an entry reject button.

The face feature registration unit 34 includes a similarity determination unit 33
Is determined to be a “visitor”, and if entry to the building 1 from the target room 3 side is permitted, the feature amount of the face obtained by the face feature amount extraction unit 32 is stored in the registration information holding device 1.
Register in 6. At the same time, the broadcast is also broadcast to the registration information holding device 26 of each room terminal device 5.

The door control device 17 controls the door 2 of the common entrance 2 of the whole building 1 according to the judgment result of the similarity judgment section 33.
control a. When the similarity determination unit 33 determines that the person is a “registrant”, the door 2a is unlocked immediately and the building 1
If you are allowed to enter and are determined to be "Visitors,"
The door 2a is unlocked after the facial feature information is registered in the registration information holding device 16 by the door unlocking section 46 of the room terminal device 5 from the target room side.

The information input unit 35 enables a user to input information by installing a touch panel on the screen of the liquid crystal monitor 12 or preparing a separate numeric keypad for inputting desired room information. In addition, a means for inputting voice such as a microphone is prepared as a means for the visitor to access the target room. If information transmission to each room 3 is necessary, the visitor can be input by voice. Can convey audio. As a sound transmission means, in addition to a method of transmitting with a normal analog signal, it is also possible to perform transmission using a network by performing digital compression.
Note that the microphone 14 can be used as the means for inputting the voice.

Next, each part of the room terminal device 5 will be described.

The camera 21 is for inputting a face image again when the person registered in the reception server 4 enters the building 1 and arrives at the target room 3. The entrance means 3 is outside the door 3a, and the realization means may be the same as that of the reception server 4.

The face area detecting section 41 detects a face area from an image input by the camera 21, and its realizing means may be the same as that of the reception server 4.

The face feature quantity extraction unit 42 is the same as that of the reception server 4.

The registration information holding device 26 constantly broadcasts face registration information from the registration information holding device 16 of the reception server 4. When a visitor registers a face at the common entrance 2 of the building 1, the visit is made. The registered information of the face feature of the user is stored in the registered information holding device 2 of each room terminal device 5.
6 is forwarded. It goes without saying that the face information of the existing registrant is also held. The storage medium in the registration information holding device 26 may be the same as that of the reception server 4.

The similarity determination unit 43 includes a face feature extraction unit 42
Is compared with the feature amount of the face registered in the registration information holding device 26 to obtain the current room 3
Whether the person standing in front of the entrance door 3a is "registrant who is allowed to enter the room 3" or "registrant who is not allowed to enter the room 3" It is determined whether it is "a visitor who has been permitted to enter from the room 3" or "other".

In this case, if the person who gives the highest similarity among all the registrants and the visitors whose face information is registered is equal to or less than a predetermined threshold value, "other" is determined and the highest similarity is given. If the person who gives the value exceeds a predetermined threshold, it is determined that the person who gives the highest similarity is the person who gives the highest similarity, and the attributes of the person (“registrant who is allowed to enter the room”, “ Registrants who are not permitted to enter ”and“ visitors ”).

Note that the method of comparing with the feature amount of the registration information holding device 26 may be a method of calculating the similarity in the same manner as the similarity determination unit 33 of the reception server 4.

The door control device 27 explains the present embodiment by not preparing a physical unlocking means for locking the door 3a, but always registers face information when unlocking the door 3a. If there is such a condition, physical unlocking means such as a key, which is very difficult to copy and pick, may be provided.

If the similarity determination unit 43 determines that the person is a registrant who is allowed to enter the room, the electronic lock of the door 3a is unlocked at that stage. In other cases, nothing is done except to notify the inside of the room 3 with the output device. FIG. 7 shows the flow of the above processing, and Table 1 below shows the correspondence table.

[0058]

[Table 1] Output device (LCD monitors 22a, 22b, speaker 23
a, 23b) are installed on the outside and inside of the door 3a, respectively, as described above, and output the contents of the judgment result of the similarity judgment unit 43 to the outside of the door 3a as a screen or sound.

In this case, in the case of “registrant permitted to enter the room”, guidance for prompting entry is displayed, and “registrant not permitted to enter the room”, In the case of "a visitor who has been permitted to enter the building from that room", the output device inside the room 3 notifies that an entrance applicant is coming. For example, a chime may sound.

On the other hand, if the room is not the one to which the visitor has given permission when the visitor registers their face in the reception server 4, no action is taken even if the visitor is recognized, including sounding a chime. . This can prevent a visitor from accessing a place other than the target room.

As described with reference to the output device of the reception server 4, when a person who appears in front of the door 2a of the common entrance 2 desires to enter his / her room 3, FIG.
The room notification screen shown in (c) is output by the output device (the liquid crystal monitor 22b) on the indoor side to allow the person to enter the building 1, and the room terminal device 5 to enter the building. When notifying that a candidate is coming,
Similarly, it outputs face information and information on whether to permit or deny entry.

The door unlocking section 46 functions as a means for permitting a visitor to enter the building 1 and a registrant or a visitor who is not permitted to enter the room 3 to enter. FIG. 7 and Table 1 summarize what steps each person with different access rights should take. In the case of the person who has been given the most access rights, the door 3a is opened by face authentication. Locking is possible, and the next is a person who is allowed access. The person who has the least access right does not respond, only giving notification to the inside such as sounding a chime.

When a visitor appears in front of the door 2a of the common entrance 2 and the room number is inputted as the destination room 3 by the information input section 35, or the visitor enters the building 1 When the user arrives in front of the door 3a of the target room 3 input in the reception server 4, or when a registrant who has not been given permission to enter the target room 3 arrives in front of the room, the indoor side Output device (LCD monitor 2
The face image of the arriving person is displayed in 2b) (see FIG. 6C), and the unlocking of the door 3a is controlled by pressing the entrance permission button 55 or the entrance refusal button 57 while viewing the image.

Further, since the permission is given to the visitor to whom permission is temporarily given, as shown in FIG. 6C, even if the admission permission button 55 is pressed, the admission valid period setting button 56 is used. The validity period can be specified.

The information input section 45 is provided for the visitor to the target room 3
If information transmission to each room 3 is required by means of voice input such as a microphone, a voice message of a visitor can be transmitted by voice input. In addition, as the means for inputting the voice, the microphone 24b can also be used.

Hereinafter, the flow of processing until a registrant who has been permitted to enter the building 1 in advance and enters the target room 3 when actually using the present apparatus, and temporarily enters the building 1 The process flow until a visitor permitted to enter the target room 3 will be described.

Registers the visitor's face image in the registration information holding device 16, and then opens the door 2a of the common entrance 2 to permit entry into the building 1 (S16).

When the visitor who has entered the building 1 arrives at the target room 3 in the building 1 and stands in front of the entrance door 3a, the room terminal 5 performs face image authentication again, and the reception server. If the visitor to whom access is permitted is authenticated in step 4, a call is made to the person in the room 3 (S17). This call corresponds to, for example, sounding a chime.

From the inside of the room 3, confirmation is made by displaying the face image captured by the camera 21 on the liquid crystal monitor 22b, and the door 3a is unlocked by the door unlocking section 46 from the inside (S18). It becomes possible for the visitor to enter room 3 which is the purpose of the visitor (S19).

On the other hand, even if an attempt is made to access a room other than the permitted room, the call cannot be made unless the visitor permitted by the reception server 4 is previously authenticated by the face authentication in the room terminal device 5. Thus, it is possible to prevent the visitor from accessing a room other than the permitted room.

As described above, according to the first embodiment,
Temporary entry / exit management for persons other than the registrant becomes possible. In other words, in order to access the door, it is necessary to show the face without fail, and in addition to restricting access to the door according to the result of personal authentication using the face, the door can be unlocked, only internal notification is possible, and no access is allowed. By applying three types of response means, such as possible, even if a person who is not normally permitted to enter a building or room, such as a visitor, is temporarily permitted to enter, without compromising security. In addition to being able to manage admission, by prohibiting access to places other than those where admission is allowed, it is possible to minimize the influence on persons who are not directly related to the person.

Next, a second embodiment will be described.

The second embodiment is an entrance management device for automatically detecting a suspicious behavior of a person who is temporarily permitted to enter and for restricting access thereafter. This will be described in detail below. I do.

FIG. 10 shows an overall schematic configuration of an entrance management device according to the second embodiment and a building such as an apartment house to which the entrance management device is applied. The difference from the first embodiment is that an authentication history server 7 as an authentication history holding means is added, and the other points are the same as in the first embodiment. Are omitted, and only different parts will be described.

The authentication history server 7 is installed, for example, in the vicinity of the reception server 4 and is connected to the reception server 4 and each room terminal device 5 via the network device 6.
All the authentication histories (authentication time, authentication result, authentication location, face image input at that time, and characteristic information of the face) in the reception server 4 and each room terminal device 5 are held (stored). In addition to this authentication history, an unauthorized access person list for registering a person who has performed an unauthorized action is also held at the same time.

The processing flow until the similarity determination unit 33 of the reception server 4 determines what kind of person is standing in front of the door 2a of the common entrance 2 is the first embodiment. Can be realized in the same way as In the second embodiment,
Further, a process of collating with information in the authentication history server 7 is also performed, and when the similarity with a person registered as an unauthorized access person in the unauthorized access person list in the authentication history server 7 becomes equal to or greater than a predetermined threshold value. Is the visitor (visitor)
Is determined to be an unauthorized access person, and any subsequent access (entering / notifying a target room by authentication at each room terminal device 5 or entering the building 1 by authentication at the reception server 4). ) Will not be accepted.

The flow of processing until the similarity determination unit 43 of the room terminal device 5 determines what kind of person stands in front of the door 3a of the room 3 is the same as that of the first embodiment. It can be realized similarly. In the second embodiment, as with the similarity determination unit 33 of the reception server 4, an inquiry is also made with the unauthorized access list in the authentication history server 7, and a specific person in the unauthorized access is identified. If a similarity equal to or greater than the predetermined threshold is given, the person standing in front of the door 3a is determined to be an unauthorized access person.

The authentication time obtained by the authentication (similarity determination), the authentication result, the authentication location (the authenticated room terminal device 5),
The face image input at that time and the feature information of the face are all transmitted to the authentication history server 7 as the authentication history, and are stored therein. As a result, it is possible to recognize an unauthorized access person who has entered the building 1 for the first time as an unauthorized access person and deny access by using the information as a list of unauthorized access users from the next authentication. Become.

For example, let X be the number of times a visitor who has been permitted to access only a specific room attempts to access a room other than the permitted room, and set a threshold value Y for determining an unauthorized access person. When the number of times X becomes equal to or greater than the threshold value Y (> 0), the person is added to the unauthorized access person list as an unauthorized access person.

According to the example shown in FIG. 11, when the threshold value of the number of times of unauthorized access is Y = 1, when a person permitted to access room A tries to access room B,
Register as an unauthorized accessor in the unauthorized accessor list,
Thereafter, both the reception server 4 and each room terminal device 5 deny access.

The output device of the room terminal device 5 (the liquid crystal monitor 2
2a, 22b and speakers 23a, 23b) can be realized in the same manner as in the first embodiment described above. In addition, based on information in the authentication history server 7, only information corresponding to the room 3 By using the liquid crystal monitor 22b on the indoor side, it is possible to check the authentication history of each room. This makes it possible to confirm whether or not the room 3 has been accessed illegally. Also, in the present embodiment, only the authentication history of the room 3 can be confirmed in consideration of privacy. However, by managing with the password of the administrator or the like, it is possible to check other rooms and all authentication histories. You can do it.

As described above, according to the second embodiment,
Suspicious behavior of temporary visitors can be automatically detected. In other words, in order to access the door, it is necessary to show the face without fail, and in addition to restricting access to the door according to the result of personal authentication using the face, the door can be unlocked, only internal notification is possible, and no access is allowed. By applying three types of response means, such as possible, it is possible to confirm that a person who has been temporarily permitted to enter a part of a plurality of rooms or places has accessed a place other than the place permitted in advance. It is possible to automatically detect the person and prevent the person from being permitted to enter thereafter.

Next, a third embodiment will be described.

In the third embodiment, the face management is performed at the time of leaving, so that it is automatically registered whether or not a certain person is in the room, and the entrance management for restricting access by others while absent is performed. The apparatus will be described in detail below.

FIG. 12 shows an overall schematic configuration of an entrance management device according to the third embodiment and a building such as an apartment house to which the entrance management device is applied. Compared to the first embodiment described above, the room management server 8 as room management information holding means is added, and a camera is also installed on the indoor side of each room terminal device 5 to exit ( The difference is that face authentication is also performed for a person who leaves the room, and the other points are the same as in the first embodiment. Therefore, a description of similar parts is omitted, and only different parts are described. I do.

FIG. 13 schematically shows a configuration of a room terminal device 5 according to the third embodiment. The difference from the first embodiment (FIG. 3) is that two cameras 21b are installed inside the door 3a as image input means for acquiring (inputting) at least a face image of a person. The rest is the same as the first embodiment. In addition,
The sign of the camera installed outside the door 3a is 21a.
And

FIG. 14 is a block diagram showing an overall configuration of a room terminal device 5 according to the third embodiment. The difference from the first embodiment (FIG. 5) is that a processing unit for the camera 21b installed inside the door 3a is added, and the rest is the same as the first embodiment. .

That is, in FIG.
The outdoor area 25a is a face area detecting unit 41a for detecting a face area from a face image input by the camera 21a, and a face feature amount for extracting a face feature amount for the face area detected by the face area detecting unit 41a.

The room management server 8 is installed, for example, near the reception server 4 and is connected to the reception server 4 and each of the room terminal devices 5 via the network device 6.
Room management information on all registrants, for example, whether the registrant is occupied, absent, if not, how long he will be absent, or a registrant who will not be able to access when the registrant is absent Holding a list.

Table 2 below summarizes the correspondence between the registrant's occupancy information and the access right for entry into each room. For example, in the section "room occupancy information", registrant A is occupied, registrant B is scheduled to be absent until February 5, 2001, and registrant Z is scheduled to be absent until February 24, 2001. It can be seen that the information has been registered.

In the column of "response method when the person is absent", what kind of access right is given to other persons when each registrant is absent.
For example, when the registrant A is absent, the setting is such that all other registrants and visitors are refused entry.
That is, in this example, no entry is allowed if no registrant A is present. When the registrant B is absent, the registrant A can enter regardless of the room information of the registrant B, but the registrant Z cannot enter. "Visitor" is a method of handling a person who is temporarily allowed to enter. Regarding "Rejection"
If the person is not present, visitors are prohibited from entering at all.In the case of "dependent on other people's room", even if you are absent, if another person is present, permission or Indicates that the setting is to allow permission.

[0102]

[Table 2] In this way, by preparing a table as shown in Table 2 for all the rooms 3 in the building 1 for which the entrance is restricted, it is possible to set an accurate entrance and exit according to the occupancy information of the person inside. Becomes possible.

If the similarity determination section 33 of the reception server 4 determines that the user is a registrant, the door control device 17 of the reception server 4 directly changes the door 2a of the common entrance 2
