  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings as appropriate.

(Embodiment 1)
<Configuration of entrance / exit management system>
First, the configuration of the entrance / exit management system 1 according to Embodiment 1 of the present invention will be described in detail with reference to FIG.

  As shown in FIG. 1, the entrance / exit management system 1 includes a camera 11, an authentication terminal 12, a management database 13, an authentication device 14, a monitor 15, a door control device 16, and a door 17. ing. The authentication device 14 includes a video monitoring unit 141, an entrance / exit management unit 142, a verification unit 143, and an authentication unit 144.

  Note that the recording medium P1 shown in FIG. 1 is held by the person to be authenticated, and records identification information and a face image of the owner. The identification information is typically an ID code unique to the person to be authenticated. Usually, the owner of the recording medium P1 matches the authentication target person who holds the recording medium P1.

  The camera 11 is a surveillance camera and photographs (captures) a predetermined range around the door 17. The camera 11 captures at least a part including the face of the person entering and leaving the room, and outputs the captured image data to the image monitoring unit 141.

  The authentication terminal 12 is installed around the door 17, reads the identification information and the face image from the recording medium P <b> 1 held by the person to be authenticated, and outputs it to the entrance / exit management unit 142.

  The management database 13 stores in advance permission information that indicates who is allowed to enter and leave the room. The permission information is typically an ID code unique to the person who enters and leaves the room.

  The authentication device 14 is based on the image data output from the camera 11 and the image data output from the authentication terminal 12, and the face image recorded by the camera 11 and the face image recorded on the recording medium P1. Is displayed and displayed on the monitor 15. The authentication device 14 collates the identification information output from the authentication terminal 12 and the permission information stored in the management database 13 and performs control to drive the door control device 16 based on the collation result.

  When the video monitoring unit 141, which is an image control unit, is notified from the entrance / exit management unit 142 that the authentication terminal 12 has read, the video monitoring unit 141 uses the video data output from the camera 11 for a predetermined period including that time. The best shot process is performed to detect the face and cut out the image around the face. The video monitoring unit 141 outputs the best shot data of the image around the face cut out by the best shot process to the matching unit 143. In addition, when the video monitoring unit 141 detects a plurality of face images of the same person from video data in a predetermined period including the time point when the authentication terminal 12 reads the identification information, the video monitoring unit 141 selects the clearest face image among the plurality of face images. The best shot data is used.

  When the entry / exit management unit 142 inputs data from the authentication terminal 12, the entry / exit management unit 142 notifies the video monitoring unit 141 that the authentication terminal 12 has read the data. Further, the entrance / exit management unit 142 outputs the face image output from the authentication terminal 12 to the collation unit 143, and outputs the identification information output from the authentication terminal 12 to the authentication unit 144.

  The collation unit 143 that is a display control unit collates the face image output from the entrance / exit management unit 142 and the face image of the best shot data output from the video monitoring unit 141 to calculate the degree of match. Specifically, the collation unit 143 extracts and digitizes a plurality of feature points in each face image, and calculates the degree of match according to the difference between the numeric values of the digitized feature points. In this case, the smaller the difference is, the higher the matching degree is, and the higher the matching degree is, the higher the possibility of being the same person. Then, the collation unit 143 outputs the two face images that have been collated and the degree of match to the monitor 15. The collation unit 143 may enlarge and display the face image of the best shot data on the monitor 15.

  The authentication unit 144 performs authentication processing by collating the identification information output from the entrance / exit management unit 142 with the permission information stored in the management database 13. As a result of the authentication process, the authentication unit 144 controls the door control device 16 to open the door when the identification information matches any permission information.

  The monitor 15 displays the two face images output from the matching unit 143 side by side, and further displays the degree of match.

  The door control device 16 is driven by the control of the authentication unit 144 to open and close the door 17.

<Operation of entrance / exit management system>
Next, operation | movement of the entrance / exit management system 1 which concerns on this Embodiment is demonstrated in detail using FIG.

  First, the camera 11 photographs a person entering or leaving the room (S1), and outputs video data to the video monitoring unit 141.

  Next, the video monitoring unit 141 performs best shot processing based on the video data, and cuts out the best shot (S2).

  Next, the authentication terminal 12 reads identification information and a face image from the recording medium P1 (S3).

  Next, the collation unit 143 calculates the degree of coincidence between the face image of the best shot data cut out by the best shot processing in the video monitoring unit 141 and the face image read from the recording medium P1 (S4).

  Next, the monitor 15 displays the face image of the entering / leaving person photographed by the camera 11 and the face image of the identification information read from the recording medium P1 side by side by the display control process of the matching unit 143 (S5). At this time, the matching unit 143 may display the calculated degree of match on the monitor 15 together with the face image. Thereby, the supervisor can compare and judge the face image displayed on the monitor 15 with reference to the degree of match.

  Note that the collation unit 143 determines that when there are a plurality of cut-out best shot face images and there are a plurality of best-shot face images whose degree of match with the face image read from the recording medium P1 is equal to or greater than a threshold value. All the face images of the best shot whose matching degree is equal to or greater than the threshold value are displayed on the monitor 15. At this time, the collation unit 143 causes the monitor 15 to display the face images having a high degree of match in order. As a result, the manager who manages the entrance / exit can simply look at the face images having the highest degree of match in order, and can efficiently compare and judge the face images. Further, even in a situation where a plurality of people including a person behind the door are shown with the door open, the manager who manages the entrance and exit can efficiently compare and judge the face image.

<Effect>
As described above, according to the present embodiment, the face image cut out from the video data by the best shot process is displayed on the monitor 15, so that the monitor can easily compare with the face image read from the recording medium P1. It can be carried out. Further, if the face image cut out from the video data by the best shot process is enlarged and displayed, the supervisor can more easily compare with the face image read from the recording medium P1.
