It is a conceptual diagram of the invention applied to this Embodiment. It is a block diagram showing the content of the entrance / exit processing part which concerns on this Embodiment. It is a figure which shows the external appearance of the entrance / exit processing apparatus which concerns on this Embodiment. It is a flowchart which shows the procedure of the entrance / exit processing by an entrance / exit processing part.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a conceptual diagram of the invention applied to this embodiment.

  As shown in FIG. 1, the entrance / exit processing device 100 includes a human sensor 110, an illuminance sensor 120, a light 130, and an entrance / exit processing unit 140. Further, the entrance / exit processing device 100 is connected to the camera 200 and the reader 210.

  The human sensor 110 is a sensor that detects that a person has entered the vicinity of the camera 200. The illuminance sensor 120 is a sensor that detects the illuminance of the imaging range of the camera 200.

  When the human sensor 110 detects that a person has entered the vicinity of the camera 200, the illuminance sensor 120 detects the illuminance of the imaging range of the camera 200. The light 130 emits light according to the illuminance detected by the illuminance sensor 120.

  Further, when the human sensor 110 detects that a room occupant has come near the camera 200, the camera 200 is activated. The image captured by the camera 200 is sent to the entrance / exit processing unit 140. The entrance / exit processing unit 140 performs processing for determining whether or not an entrance person is allowed to enter when the face of the entrance person is reflected in the image captured by the camera 200. In this embodiment, an appropriate code image is shown. Judgment is made. For example, when entry is permitted, an unlock signal for unlocking the locked door is transmitted to activate the connected unlocking device.

  The reader 210 reads a key for room authentication when a room entrant requests room entry. For example, when the key is a card key with an RFID (Radio Frequency IDentifier) tag, the reader 210 is an RFID reader.

FIG. 2 is a block diagram showing the contents of the entrance / exit processing unit according to the present embodiment.
As shown in FIG. 2, the entrance / exit processing unit 140 includes a face determination unit 141, an authentication unit 142, and a log processing unit 143.

The face determination unit 141 determines whether the room occupant's face is shown in the image captured by the camera 200.
When the face determination unit 141 determines that the face is captured, the authentication unit 142 determines whether the authentication signal read by the reader 210 is appropriate. Note that the reader 210 is replaced with a configuration that reads image data from the camera 200 rather than a single reader as a physical configuration when room authentication is performed using only a code image. Further, even when the room authentication is performed with a code image, a single reader can be provided as a superposed physical configuration, and the room 210 may be authenticated by a method other than the code image by the reader 210.

  When the authentication unit 142 determines that the authentication signal is appropriate, the log processing unit 143 records and stores an image captured by the camera 200 at the time of authentication as a log.

FIG. 3 is a diagram showing an appearance of the entrance / exit processing device according to the present embodiment.
As shown in FIG. 3, the entrance / exit processing apparatus 100 has a camera 200 integrated therein, for example. Around the camera 200, four LED (Light Emitting Diode) lights are incorporated as a set of lights 130.

  Such an entry / exit processing apparatus 100 is used by being installed beside a door installed at an entrance of an area where entry restriction is applied.

  Note that all four lights 130 may be illuminated at once, but some of the four lights 130 may be illuminated according to the illuminance detected by the illuminance sensor 120. Further, for example, irradiation may be performed in the order of total number → upper left → upper right → lower left → lower right → total number. Paper and cards with printed code images may be placed in card cases. At this time, if four lights 130 are irradiated at a time, the code image may not be accurately read due to reflection on the card case. Therefore, by forming a pattern and irradiating the light 130 in order, it is possible to prevent the code image from being read due to reflection of light on the card case or the like, and the code image can be read accurately.

  Furthermore, the light 130 is desirably white. When a color barcode is used as the code image and the entrance / exit processing device 100 is installed in an outer corridor or the like, for example, when the morning sun or sunset red is strong, the color of the color barcode is It may not be read correctly. Therefore, the color of the color barcode can be accurately read by making the light 130 white.

FIG. 4 is a flowchart showing the procedure of the entry / exit processing by the entry / exit processing unit. In the following, the process illustrated in FIG. 4 will be described in order of step number.
[Step S11] The face determination unit 141 determines whether or not a face is included in an image captured by the camera 200. If it is determined that a face is captured, the process proceeds to step S12. If it is determined that no face is captured, the process returns to step S11.

  [Step S12] When the face determination unit 141 determines that a face is captured and receives an authentication signal from the reader 210, the authentication unit 142 determines whether the authentication signal is appropriate. If it is determined that the authentication signal is appropriate, the process proceeds to step S13. If it is determined that the authentication signal is not appropriate, the process returns to step S11.

  [Step S13] When the authentication unit 142 determines that the authentication signal is appropriate, the log processing unit 143 records and stores the image captured by the camera 200 as a log, and ends the process.

  According to the entrance / exit processing apparatus 100 of the present invention, the authentication unit 142 authenticates the entrance / exit only when the face determination unit 141 determines that the face of the authenticator is reflected, and the log processing unit 143 performs the authentication at the time of authentication. Since the image captured by the camera 200 is logged, by logging the face of the erroneous authenticator with a simple configuration device, it is possible to suppress erroneous authentication and thereby perform more appropriate authentication. In other words, the authentication key is copied maliciously, for example, by judging only whether the face of the certifier is visible without performing complex processing such as face authentication using the face of the occupant as a key. Even if authentication is avoided by misauthentication, the face of the miscertified person is always recorded as a log. It is a great merit to suppress erroneous authentication by always logging the face of the erroneous authenticator.

  The above processing functions can be realized by a computer. In that case, an entry / exit processing program describing the processing contents of the functions that the entry / exit processing device should have is provided. By executing the entry / exit processing program on a computer, the above processing functions are realized on the computer. The entrance / exit processing program describing the processing content 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. Magnetic recording devices include HDDs, FDs, magnetic tapes, and the like. Optical discs include DVD (Digital Versatile Disc), DVD-RAM, CD-ROM, CD-R (Recordable) / RW (ReWritable), and the like. Examples of the magneto-optical recording device include an MO (Magneto Optical disk).

  When the entry / exit processing program is distributed, for example, a portable recording medium such as a DVD or CD-ROM in which the entry / exit processing program is recorded is sold. It is also possible to store the program in a storage device of the server computer and transfer the entry / exit processing program from the server computer to another computer via the network.

  The computer that executes the room entry / exit processing program stores, for example, the room entry / exit processing program recorded on the portable recording medium or the room entry / exit processing program transferred from the server computer in its own storage device. Then, the computer reads the entry / exit processing program from its own storage device, and executes processing according to the entry / exit processing program. The computer can also read the room entry / exit processing program directly from the portable recording medium and execute processing according to the room entry / exit processing program. In addition, each time the entrance / exit processing program is transferred from the server computer, the computer can sequentially execute processing according to the received entrance / exit processing program.

  The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present invention.

  The above merely illustrates the principle of the present invention. In addition, many modifications and changes can be made by those skilled in the art, and the present invention is not limited to the precise configuration and application shown and described above, and all corresponding modifications and equivalents may be And the equivalents thereof are considered to be within the scope of the invention.

  The room entry / exit processing apparatus 100 may be configured not to perform room entry / exit processing unless the person entering the room is within a certain distance from the camera 200. If the occupant is within a certain distance range from the camera 200, the size of the occupant's face is necessarily limited to the certain size range. Therefore, at this time, the face determination unit 141 may determine that the face is captured only when the size of the face is within a certain size range. According to this, for example, a face can be prevented from being displayed and disguised on a screen of a smartphone or the like.

  Specifically, as to whether or not the person entering the room is within a certain distance range from the camera 200, it can be considered that the entrance / exit processing cannot be performed unless the human sensor 110 approaches the certain range. Further, this may be done by limiting the focal length of the camera 200. Further, this may be done by limiting the irradiation range of the light 130.

  Moreover, you may mount a thermosensor in the entrance / exit processing apparatus 100. At this time, the face determination unit 141 may determine that the face of the room occupant is reflected only when the temperature detected by the thermosensor is within a certain range for the portion determined to have a face. According to this, even if the size is within a certain range, it is possible to prevent the face from being camouflaged with a mask or the like.

  In addition, when the authentication unit 142 determines that the authentication signal is appropriate, the log processing unit 143 records and stores an image captured by the camera 200 as a log, which is stored in the entrance / exit processing device 100. However, the present invention is not limited to this, and a mode in which data is transmitted to a connected server or the like and recorded / stored in the server or the like can be considered.
