Description

  The present invention relates to an entrance / exit management system at an entrance / exit that permits entry and exit of only authorized personnel, and in particular, simplifies personal authentication for the purpose of restricting entrance and does not perform personal authentication. The present invention relates to a system that can detect unauthorized visitors.

  An example of a first method of a conventional entrance / exit management system is described in Patent Document 1. In this conventional entrance / exit management system, when a card is inserted into a card reader installed on the entrance side of the entrance / exit, the unlocking permission information stored in the entrance / exit management device and the card information are authenticated. The electric lock is unlocked to enter the room, and at the same time, the number of people who enter the room is counted with an optical sensor that detects the person entering the room. At this time, when there are a plurality of people entering the room, a warning buzzer is sounded to try to alert the surrounding people.

  Next, an example of the second method of the conventional entrance / exit management system is described in Patent Document 2. An entrance having an electric lock, a card reader, a registrant storage means, an admission permission judging means, comparing personal information when an admission application is made by the card reader, discriminating admission permission, and storing the number of admission permitted, and an entrance An image captured by a monitoring camera that monitors the vicinity is processed to measure the number of people, and the electric lock is unlocked by matching the number of people allowed to enter and the number of people counted from the image. In addition, an alarm is issued when the number of persons identified by the image processing means increases during unlocking of the electric lock.

  An example of a similar third method is described in Patent Document 3. Similar to the second method, an authentication means such as a card reader or a biometric information authentication device and an image pick-up by a monitoring camera or a means for monitoring by a passage sensor using infrared rays or laser light are provided. When a change is detected by the monitoring camera image or the passage sensor in an area where the authorized passerby does not pass or an area where an illegal passer may pass in the openable / closable entrance of the area It is determined that illegal traffic occurred. When unauthorized passers are detected, door unlock control, warning, and history information are recorded.

  In other words, both methods detect that unauthorized traffic has occurred in the vicinity of the entrance / exit from the comparison of the authentication result by the authentication device used in close proximity and the number of authenticated persons, and the change in the number of people by the camera or passing sensor monitoring the vicinity of the entrance. It performs unlocking control, alarms, and history information recording.

The first problem is that, in the first method and the third method, the method of detecting by a passage sensor such as an optical sensor may not be able to accurately detect the entrance of a plurality of people.
The reason is that, when a plurality of people try to enter the room, it is difficult to accurately grasp the number of people because the overlap cannot be detected and they are detected in a lump without interruption.

The second problem is related to the first problem, in that a stay may occur in front of a room for a plurality of people entering the room.
The reason for this is that the process is basically based on the process of entering a single person with one person being authenticated, so when multiple persons try to enter the room, the next person will be authenticated and passed if one person's passage process is not completed. Because there is no. In particular, in the third method, even if a person who intends to pass normally is approaching a person who is performing an authentication act to determine areas where illegal passers may pass, it is determined whether or not This is because if it exists in the area, it is detected as an unauthorized passer.

  The third problem is that in the second method and the third method, there is a high possibility that a person who approaches the vicinity of the entrance is detected as illegal traffic regardless of the intention of entering the room.

Furthermore, for the same reason, the fourth problem is that the person who performed the authentication act leaves without entering the room, or a third party who does not perform the authentication act immediately after performing the authentication act passes instead. However, it cannot be detected.
The reason for this is that the determination of unauthorized traffic is simply based on the comparison of the number of people authenticated by the authenticator and the number of people detected by image processing, or the change in the number of people in the area.

  SUMMARY OF THE INVENTION An object of the present invention is to provide an entrance / exit management system that can reliably detect the occurrence of unauthorized traffic for the passage of a plurality of people at the entrance, which is a problem of the prior art as described above.

  Another object of the present invention is to provide an entrance / exit management system that reduces false detection of an authorized passer or a passerby in the vicinity of an entrance as an illegal passer.

  Still another object of the present invention is to improve the convenience of reducing the conscious authentication act of a passer-by without causing stagnation even at an entrance / exit with a high pass frequency, and the high security of detecting the unauthorized passer-by. The purpose is to provide a compatible entrance / exit management system.

  Still another object of the present invention is to reduce the conscious authentication act, that is, on which floor the ID card holder who is the target to be managed exists by performing the entrance / exit authentication unconsciously, and The object is to provide an entrance / exit management system that enables location management of existing locations.

  Therefore, in the entrance / exit management system of the present invention, the traffic control means for controlling the passage of the entrance / exit through electrical control such as automatic doors and electric locks, and various information of the person permitted to enter the entrance / exit are registered. Passer information storage means, personal authentication means for collating identification information held by the passer and identification information registered in the passer information storage means, and a camera for photographing a predetermined range around the entrance / exit And image processing means for detecting a person from the image information of the camera and outputting the position of the person as coordinate information in a spatial coordinate system of a predetermined range captured by the camera, and authentication authenticated by the personal authentication means A person who individually outputs coordinate information from the image processing means to a non-authenticated person and a non-authenticated person, and tracks the positions of the authenticator and the non-authenticated person based on the output coordinate information. And tracking means, characterized in that it comprises a and determining traffic determination means the passage propriety based on the output results of the person tracking means and the personal authentication unit.

  The first effect is that it is possible to reliably detect the occurrence of unauthorized traffic for the traffic of a plurality of people at the doorway.

  The reason is that an unauthorized passer who does not have an ID card is tracked up to the entrance / exit by image processing, and it is determined that the unauthorized passer-up is made with the intention of unauthorized intrusion.

  The second effect is that it is possible to reduce erroneous detection of a regular passerby or a passerby near an entrance as an illegal passer.

  The reason is that the ID card holder and non-holder are separately tracked up to the entrance / exit in the image.

  The third effect is that it is possible to achieve both the improvement of convenience that can reduce the conscious authentication act of a passer-by and the high security of the detection of the unauthorized passer-by without causing stay even at an entrance / exit with a high pass frequency. is there.

  The reason is that an ID card capable of long-distance communication and an RFID reader are used, authentication is possible without the need for conscious authentication, and the vicinity of the entrance / exit including the authentication communication range is photographed with an upper camera. This is because the unauthorized passer detection means by the individual tracking process can cope with simultaneous continuous passage of a plurality of persons.

  The fourth effect is that the ID card holder can manage the floor on which the ID card holder exists and the location of the ID card holder.

  The reason is that ID cards and RFID readers capable of long-distance communication are used, and authentication is possible without the need for conscious authentication. This is because it is possible to manage not performing authentication by detecting unauthorized traffic.

  Next, the best mode for carrying out the invention will be described in detail with reference to the drawings.

  Referring to FIG. 1, in the first embodiment of the present invention, traffic control means 110 such as an automatic door or an electric lock, an ID card 120 held by a regular passer, and information on the ID card are 2 to 3 m. An RFID reader 130 that communicates at a distance, an upper camera 140, an image processing device 150 that processes image information of the upper camera, a control computer 160 that controls and processes the operation of the present invention, and detects unauthorized passers-by An alarm display 170 that alerts the surroundings based on the alarm notification when the alarm is issued, a monitoring camera 180 that captures the vicinity of the entrance when the alarm is received, and a monitoring computer 190 that captures and stores the monitoring camera image. .

  The traffic control means 110 includes a door 111 and a door control unit 112.

  The image processing apparatus 150 includes a person detection unit 151 that detects a person from the image data and converts it into a symbol, and a coordinate output unit 152 that outputs a coordinate value of the person symbol A01.

  The control computer 160 includes an ID authentication database 161, an ID authentication unit 162, an image tracking comparison unit 163, and a passage permission determination unit 164.

  Each of these means generally operates as follows.

Means included in the image processing apparatus 150 will be described with reference to FIG.
The person detection means 151 may be a person detection method based on a general difference method from continuous still images from the upper camera 140, or a distance image camera, a thermograph camera, or the like is used as the upper camera 140, and distance data or Detection may be performed by taking into account human-specific data from the body temperature profile. A symbol A0n of a person (n is a variable depending on the number of people) is set at the center of gravity position from the graphic data determined and detected as a person. The coordinate output unit 152 outputs the coordinate value of the human symbol A0n to the control computer 160 at a time interval that defines the coordinate value of the person symbol A0n in the spatial coordinate XY1 to be defined.

  The ID authentication database 161 included in the control computer 160 stores and saves an ID and personal information for which application for permission to pass through the entrance is made in advance. The ID authentication database 161 updates and updates the latest information when a re-application for registration occurs or periodically from the host system. The ID authentication unit 162 compares the ID transmitted from the RFID reader 130 with the passage permission ID registered in the ID authentication database 161 when the RFID reader 130 reads the information on the ID card 120, and temporarily determines the passage permission. Make a decision.

The image tracking comparison unit 163 will be described with reference to FIG. The image tracking / comparison unit 163 defines a spatial coordinate XY2 equivalent to that of the image processing apparatus 150, and defines a communication boundary line Z1 and a traffic will determination reference line Z2 with the communication range of the RFID reader as a threshold value in the spatial coordinate XY2. . The ID card data acquisition time t0n from the RFID reader is compared with the timing of the coordinate value acquisition time t1n when the human symbol A0n output from the image processing device 150 passes through the communication boundary line Z1, and the ID holder or not holds It is determined whether it is a person. In the case of an ID holder, the symbol of a person is defined as A1n, and in the case of a non-holder, it is defined as A2n. Since the coordinate values of A1n and A2n are periodically transmitted from the image processing apparatus 150, they are plotted on the space coordinates XY2.
The passage permission determination means 164 issues an alarm notification when A1n or A2n exceeds the passage intention determination reference line Z2 when A1n is unlocked, and when A2n is not permitted.

  The door control unit 112 included in the traffic control unit 110 receives the unlocking permission from the control computer 160, opens the door 111, and informs the control computer whether the door 111 is unlocked.

  Next, the operation of the best mode for carrying out the present invention will be described using specific examples.

  FIG. 12 shows an arrangement example of components around the entrance / exit in the first embodiment. Here, the communication range Z1 of the RFID reader 130 is arranged to be included in the imaging range W1 of the upper camera 140. At this time, it is sufficient that this relationship is established at the height of the ID card 120 worn by the passerby. In addition, when the ceiling height is low and the upper camera 140 cannot take a sufficient imaging range, it is installed obliquely upward like the RFID reader 130 and replaced with the space coordinate XY1 by coordinate conversion. In addition, although the traffic will determination reference line Z2 is arranged on the virtual coordinates, it is arranged slightly nearer when convenience is emphasized near the door 111, and is arranged near the door 111 when importance is placed on security.
