The external intruder detection apparatus 100 according to the embodiment of the present invention may be installed in any place requiring security such as a school or a security zone. In the following description, an external intruder detection apparatus 100 that is installed in a school and is capable of monitoring an unauthorized visitor by determining whether or not an intruder intruding into the school is intruded will be described.

Referring to FIGS. 1 and 2, an external intruder detection apparatus 100 according to an embodiment of the present invention includes an image acquisition unit 10, a reader 20, and a control unit 30.

The image acquiring unit 10 can acquire image information by photographing a visitor. For example, the image acquiring unit 10 may be a dome camera, a square camera, a PTZ (Pan-tilt-zoom) CCTV camera, a pinhole camera, or the like,

The image acquiring unit 10 may be installed at a plurality of intervals at predetermined intervals to acquire images with respect to the entire area of the campus. Here, the image obtaining unit 10 may detect the motion of a user using a motion detection method.

For example, when the temporally stored image information is compared with the current screen and the previous screen, the image obtaining unit 10 may collect the image information and transmit the collected image information to the control unit 30 when the changed part occurs over the reference value.

The reader 20 is a device capable of data communication with an apparatus such as an RFID tag possessed by a visitor.

Although the reader 20 can be installed at a doorway entering or leaving the campus, the reader 20 can be arranged at regular intervals in the outskirts of the campus in case of intruding into a place other than the entrance door.

In this manner, the reader 20 can be disposed at predetermined intervals around the exterior of the campus to form RF fields. Here, the interval at which the reader 20 is installed is set such that the RF signal area covered by each reader 20 can be partially overlapped so that no empty space is generated in the RF signal area.

The reader 20 receives the unique identification information for primarily determining whether or not the user enters the RF field. That is, the reader 20 requests unique identification information from the passenger detected by the image acquisition unit 10.

The reader 20 transmits the unique identification information received from the user to the controller 30. In addition, even when the reader 20 requests unique identification information to the user, but does not receive the requested unique identification information, the controller 20 transmits a corresponding signal indicating that the unique identification information is not received to the controller 30.

In the present embodiment, the reader 20 capable of recognizing the RFID tag is used. However, the present invention is not limited to this, and a mobile phone, a tablet PC, or the like may be used instead of the RFID tag, A reader 20 capable of authenticating a terminal such as a reader can be used. Here, the reader 20 may be an active RFID tag or an active RFID tag that exchanges information with a terminal, or may be a passive RFID tag or receiving information from the terminal.

The alarm sound output unit 42 may be constituted by a siren or the like so as to recognize the emergency situation.

Also, when the passenger has the RFID tag, the reader receives the authentication data from the passenger, and the controller receives the data from the passenger and determines that the passenger is the unauthorized passenger by judging that the passenger is the same as the previously stored data.

If it is determined that the user is not an unauthorized person through the reader 20, the control unit 30 extracts a character part of the visitor from the photographed image information, compares the character part with the previously stored character part, The second judgment is made. Here, the feature may be the key or face of the guest.

If the second judgment is made based on the key of the visitor, the control unit 30 extracts the key information about the visitor from the image information, extracts key information about the extracted visitor, predetermined key information And judges that the user is an unauthorized person if the key of the user exceeds the preset key information.

For example, in the case of an elementary school, the control unit sets the key information as a reference for distinguishing the adult from the student to 160 cm, judges that the student is 160 cm or less in height, and judges the student as an unauthorized person if the height of the student is 160 cm or more have.

On the other hand, when the second judgment is made through the face of the passenger, the control unit 30 extracts the minutiae of the face of the passenger from the image information, and judges that the minutiae are unauthorized passengers when the minutiae are not minutiae points of the previously registered face.

For example, the control unit 30 extracts the feature points of the face of the user from the image information acquired from the image acquisition unit 10 using the SURF (Speed Up Robust Features) algorithm, and matches the extracted feature points with the previously stored feature point information It is possible to judge whether or not the user is unauthorized access.

On the other hand, the control unit 30 may include a storage unit 31 for storing unique identification information on an interested party, key setting information on a visitor, and minutia information about the face of a person concerned in order to judge whether or not the first trespass has been invaded .

The control unit 30 makes a secondary determination based on the key or the face of the passenger, and when it is determined that the passenger is an unauthorized passenger, the control unit 30 can output video information or alarm sound to the passenger through the control server 40 described above.
