<First Embodiment>

  Next, the unlocking control process in the first embodiment of the present invention will be described with reference to FIG.

  3 is a process in which the CPU 201 of the information processing apparatus 101 reads and executes a predetermined control program.

  In step S <b> 301, the CPU 201 of the information processing apparatus 101 acquires a video shot by an imaging device (camera). Further, information (ID) identifying the imaging device that has captured the video is acquired from the imaging device.

  In step S302, the CPU 201 of the information processing apparatus 101 analyzes the video acquired in step S301. Specifically, the two-dimensional code shown in the video acquired in step S301 is detected, and processing for acquiring an ID (identification information) indicated by the two-dimensional code is executed. In the analysis, for example, the acquired video data is extracted for each frame and analyzed as image data (still image).

  Note that the two-dimensional code in the embodiment of the present invention refers to a code configured by arranging a plurality of cells as disclosed in, for example, Japanese Patent Laid-Open No. 2012-78973. When the two-dimensional code described in JP 2012-78973 A is included in a still image, the ID (identification information) of the two-dimensional code and the still image of the two-dimensional code are included. The position (coordinates) inside is obtained. In this embodiment, it is assumed that the information processing apparatus 101 has an application that detects a two-dimensional code and acquires its ID and a position (coordinates) in a still image.

  Any two-dimensional code may be used as long as a plurality of two-dimensional codes can be recognized at a time. An example of the two-dimensional code is shown in FIG.

  In step S303, the CPU 201 of the information processing apparatus 101 determines whether all the IDs acquired in step S302 are registered in the master table (for example, FIG. 6).

  That is, it is determined whether a person who is not registered as a user who uses the conference room is included.

  When all the acquired IDs are registered in the master table (step S303: YES), the process proceeds to step S304.

  If there is an ID that is not registered in the master table (step S303: NO), the processing shown in this flowchart is terminated. That is, the entrance is not unlocked so that a person other than the user who uses the conference room cannot use the conference room. At this time, error information indicating that unlocking cannot be performed may be transmitted. The same applies to cases where NO is determined in steps S304, S305, and S306.

  In step S304, the CPU 201 of the information processing apparatus 101 determines whether or not all IDs acquired in step S302 belong to the same group using the master table.

  As shown in FIG. 6, in the master table, it is assumed that two-dimensional code information (ID) and a group are associated with each other.

  If all IDs belong to the same group (step S304: YES), the process proceeds to step S305.

  If an ID belonging to a different group is included (step S304: NO), the process of this flowchart ends.

  In step S305, the CPU 201 of the information processing apparatus 101 determines whether the number of IDs acquired in step S302 matches the number of IDs belonging to the group determined in step S304. That is, it is determined whether all IDs belonging to the same group have been acquired (whether there are any missing IDs).

  If they match (step S305: YES), the process proceeds to step S306.

  If they do not match (step S305: NO), the processing shown in this flowchart is terminated.

  In step S306, the CPU 201 of the information processing apparatus 101 determines whether the number of IDs acquired in step S302 matches the number of persons shown in the analysis target video.

  That is, it is determined whether one person has two or more two-dimensional codes. For example, even if it is determined in step S305 that there are no missing IDs, if one person possesses two or more two-dimensional codes, not all persons entering the room are available. Become. Therefore, it is confirmed by the processing in this step that all the members are prepared.

  Note that the number of persons can be determined by using a known face detection technique or the like.

  If they match (step S306: YES), the process proceeds to step S307.

  If they do not match (step S306: NO), the process of this flowchart is terminated.

  In step S307, the CPU 201 of the information processing apparatus 101 issues an instruction to unlock to the locking system. And the process of this flowchart is complete | finished.

  In the locking system, the entrance is unlocked in accordance with the unlocking instruction from the information processing apparatus in step S307.

  Note that the entrance to be unlocked is based on a data table (FIG. 11 as an example) in which the identification information of the network camera is associated with the entrance monitored (in charge) by the network camera. , Determined by the ID acquired in step S301. That is, the entrance associated with the network camera (camera ID acquired in step S301) that captured the video acquired in step S301 is unlocked.

FIG. 6 is an example of a master table stored in the information processing apparatus 101 according to the first embodiment of this invention. As shown in FIG. 6, it is composed of groups, two-dimensional code information (ID), and sections.
<Second Embodiment>

  Next, unlocking control processing in the second embodiment of the present invention will be described with reference to FIG.

  Note that the process shown in the flowchart of FIG. 4 is a process in which the CPU 201 of the information processing apparatus 101 reads and executes a predetermined control program.

  Here, the processing of steps S301 to S307 in FIG. 4 is the same as the processing of S301 to S307 in FIG. The present embodiment (second embodiment) is an embodiment in which the process shown in S401 is added after the process in step S306 in the first embodiment.

  In the second embodiment, the master table shown in FIG. 7 is used.

  In step S401, the CPU 201 of the information processing apparatus 101 determines the face included in the video analyzed in step S302 and the face image specified by the ID acquired in step S302 (face image specified by the master table shown in FIG. 7). To determine whether the faces of the same person. Specifically, for example, the similarity between the facial image feature amount shown in FIG. 7 and the facial feature amount included in the video analyzed in step S302 is calculated, and the calculated similarity satisfies a predetermined value. It can be determined by whether or not.

  If it is determined that the faces are the same person (step S401: YES), the process proceeds to step S307.

  If it is determined that the faces are not the same person (step S401: NO), the processing of this flowchart is terminated.

Thus, in this embodiment, face recognition processing is performed based on the face image registered in the master table. Thereby, for example, even when a two-dimensional code is copied and another person tries to enter the room, it is possible to prevent another person from entering the room by combining with face recognition.

The present embodiment (third embodiment) is an embodiment in which the process shown in S501 is added after the process of step S401 in the second embodiment.

  In the third embodiment, the master table shown in FIG. 8 is used.

  In step S501, the CPU 201 of the information processing apparatus 101 determines whether the number of faces determined to be the same person in step S401 satisfies the numerical value set in the security level shown in FIG.

  For example, in FIG. 10, entering the 206 meeting room means that there must be two or more faces determined to be the same person. Similarly, one 302 meeting room and three or more reception rooms are required.

  Which conference room is to be entered can be specified from the identification information of the network camera acquired in step S301.

  If it is determined that the security level is satisfied (step S501: YES), the process proceeds to step S307.

  If it is determined that the security level is not satisfied (step S501: NO), the processing shown in this flowchart is terminated.

  Further, as shown in FIG. 9, may be registered or previously which groups utilize any conference room, the registered group can be controlled not only available conference rooms that have been registered.
