The visitor 50 (image user) who performed the image user registration uses the information terminal 70 or the like, for example, among the photographed images photographed in the theme park 10 by the photographer, the photographed image in which he / she is reflected. Can be acquired from the image management apparatus 20.

  The visitor 50 who performs image user registration inputs the authentication information 112 and the face information 113 to the image management apparatus 20 using, for example, the information terminal 70 or the like. When such information is input from the visitor 50, the image management apparatus 20 assigns a unique image user ID 111 to the visitor 50 and associates the input information with the image user ID 111. Store in database 110. At this time, nothing is recorded in the movement trajectory data 114 and it is set to an empty state.

3. Entrance The photographer enters the theme park 10 with the camera 40. The image user also enters the theme park 10 with the portable terminal 80. The camera 40 and the portable terminal 80 possessed by the photographer or image user in the theme park 10 may be owned by the photographer or image user, or loaned from the operator of the theme park 10 or the like. It may be what was done.

  When the photographer shoots in the theme park 10, the camera 40 records the captured image data in the memory card 45 and transmits the image data to the image management apparatus 20 through data communication via the communication unit 48. . Metadata relating to the image data is added to the image data recorded in the memory card 45 and transmitted to the image management apparatus 20. The metadata includes, for example, the shooting date and time, the camera ID of the camera 40 used for shooting, the position of the camera 40 (shooting position) detected during shooting by the position detection unit 49a, and the posture detection unit 49b detected during shooting. The direction (photographing direction) of the camera 40 is included.

  When the image management apparatus 20 receives the image data and the metadata, the image management apparatus 20 performs a known face recognition process on the image data. By the face recognition process, the image management apparatus 20 detects face information related to the facial appearance included in the image data. Thereafter, the image management apparatus 20 associates the detected face information with the received image data and metadata and stores them in the image database 120. The same data in the metadata is stored in the shooting date / time 121, the camera ID 122, the shooting position 125, and the shooting direction 126, the received image data itself is stored in the image data 123, and the detected face information is stored in the face information 124, respectively. Stored.

  When the image user is moving in the theme park 10, the portable terminal 80 periodically detects the current position by the position detection unit 86 and records it in the memory card 82. Thereby, the movement trajectory data of the image user is recorded in the memory card 82.

4). Exit When the photographer and the image user who have received the loan of the camera 40 or the portable terminal 80 leave the theme park 10, they return the loaned camera 40 or the portable terminal 80 to the operator of the theme park 10.

  When leaving the theme park 10, the image user inputs movement trajectory data recorded on the memory card 82 of the portable terminal 80 to the image management device 20. For example, when leaving the theme park 10, the mobile terminal 80 is temporarily deposited with the staff of the theme park 10, and the movement trajectory data in the mobile terminal 80 is image-managed using the dedicated terminal from the mobile terminal 80 received by the staff. Input to the device 20. At this time, the image user ID 111 of the image user possessing the portable terminal 80 is input to the image management apparatus 20 together with the movement trajectory data. The control unit 22 of the image management apparatus 20 stores the input movement trajectory data 114 in the image user database 110 in association with the input image user ID 111.

5. Image acquisition After leaving the theme park 10, the image user acquires the image data 123 photographed by the photographer from the image database 120 using the information terminal 70 such as a home personal computer or a street kiosk terminal. be able to. Hereinafter, the acquisition procedure of the image data 123 will be described.

  FIG. 6 is a flowchart of image acquisition processing executed by the control unit 22. This process is included in a control program that the control unit 22 reads from the ROM 23 and executes.

  First, in step S <b> 100, the control unit 22 authenticates the image user based on the authentication information input by the image user using, for example, the information terminal 70 and the authentication information 112 of the image user database 110. For example, the input authentication information is searched from the image user database 110, and a record having the matching authentication information 112 is searched. Thereby, the image user ID 111, the face information 113, and the movement locus data 114 of the image user are specified. If the input authentication information is not found in the image user database 110, that is, if the authentication fails, the image user is notified of the fact and the processing in FIG. 6 is terminated.

  In step S120, the control unit 22 searches the image database 120 for the image data 123 in which the image user is reflected, using the specified face information 113. Specifically, a record including face information 124 that matches the specified face information 113 is searched from the image database 120, and image data 123 is extracted from the record.

  In subsequent step S <b> 130, the control unit 22 searches the image database 120 for the image data 123 in which the image user is reflected, based on the specified movement locus data 114. A specific search method will be described in detail later.

  Here, in addition to the image search using the specified face information 113, the image search using the specified movement trajectory data 114 is performed in order to cope with a face recognition failure. For example, the comparison between the specified face information 113 and the face information 124 in the image database 120 may fail depending on the lighting condition, face orientation, and the like. Image data is not leaked from the search.

  In step S140, the control unit 22 displays a list of the image data 123 extracted by the image search executed in steps S120 and S130 on the display screen of the information terminal 70. For example, thumbnail images of those image data 123 are displayed as a list on the display screen of the information terminal 70.

  The image user performs an operation of selecting the image data 123 to be acquired from the image data 123 displayed as a list on the information terminal 70. In response to this selection operation, the information terminal 70 transmits an image request signal for requesting the selected image data 123 to the image management apparatus 20.

  In step S150, the control unit 22 receives the image request signal transmitted from the information terminal 70. In step S160, the image data 123 corresponding to the image request signal is transmitted to the information terminal 70. Accordingly, the image user can acquire the image data 123 and use it for various purposes such as printing.

  Next, a search method for the image data 123 based on the movement trajectory data 114 will be described.

  FIGS. 7A and 7B are diagrams in which movement trajectory data 114, shooting position 125, and shooting direction 126 are plotted on a virtual ground surface. The following description will be made with attention paid to one piece of movement trajectory data 114 recorded on a specific day and one piece of image data 123 taken on the same day.

  Points P1 to P6 in FIG. 7A are points included in the moving trajectory data 114 of interest. The point P1 is 13:29, the point P2 is 13:30, and the point P3 is 13:31. The point P4 is recorded at 13:32, the point P5 is recorded at 13:33, and the point P6 is recorded at 13:34. That is, the movement trajectory data 114 shown in FIG. 7A indicates that the image user is moving from the lower left in FIG. 7A toward the upper right in FIG. 7A. On the other hand, the shooting position 125 of the image data 123 of interest is a point P7 located at the lower right of the point P4, and the shooting direction 126 is the direction of the point P4 as indicated by an arrow 131 in FIG. .

  The control unit 22 first specifies the shooting range 130 of the image data 123 based on the shooting position 125 and the shooting direction 126. The shooting range 130 can be specified from the number of pixels of the image data 123, the focal length at the time of shooting, and the like. For example, the lateral expansion of the shooting range 130 is increased as the focal length is shorter. Further, the length of the imaging range 130 in the depth direction is increased as the number of pixels is increased. Note that the shooting range 130 may be specified in consideration of the depth of field and the focus position at the time of shooting. For example, when the depth of field is shallow, only a certain range from the focus position may be considered as the shooting range 130.

  After specifying the shooting range 130, the control unit 22 notices that the point P4 included in the movement trajectory data 114 is in the shooting range 130, and the recording date and time of the point P4 in the shooting range 130 is noticed. Since it coincides with the shooting date 121 of the image data 123 to be determined, it is determined that the image user is reflected in the image data 123.

  In addition, in the comparison between the recording date and time of the moving trajectory data 114 to be noticed and the shooting date and time 121 of the noticed image data 123, the control unit 22 determines that they are the same even if they are not exactly the same. There are things to do. For example, if the difference between the recording date / time of the movement trajectory data 114 and the shooting date / time 121 is within a predetermined time (for example, 3 seconds), the control unit 22 determines that the recording date / time of the moving trajectory data 114 matches the shooting date / time 121. judge.

  Even if the points included in the movement trajectory data 114 are not included in the shooting range 130, as shown in FIG. 7B, the movement trajectory extrapolated from a plurality of points included in the movement trajectory data 114 is provided. If the date and time 132 entered the imaging range 130 estimated from the plurality of points coincides with the imaging date and time 121 of the image data 123 of interest, the control unit 22 It is determined that the user is reflected in the image data 123.

  In step S130 of the process shown in FIG. 6, the control unit 22 compares the movement trajectory data 114 described above with the shooting date / time 121, the shooting position 125, and the shooting direction 126 for each record included in the image database 120. Run. Thereby, the image data 123 in which the image user is reflected is extracted.

(2) When the person who is the subject is performing a predetermined hand sign The control unit 93 of the fixed camera 90 performs a predetermined hand sign (for example, a piece) on the image data by pattern matching or the like every time the image data is created. It is determined whether or not a sign is included. Then, when a hand sign is included in the image data, the image data is transmitted to the image management apparatus 20.

(3) When the facial expression of the person who is the subject is smiling The control unit 93 of the fixed camera 90 performs well-known smile detection processing such as pattern matching on the image data every time image data is created. Run. When at least one of the faces included in the image data is a smile, the image data is transmitted to the image management apparatus 20.

(4) When a predetermined sound is input from the microphone 96 The control unit 93 of the fixed camera 90 performs a well-known sound recognition process on the sound signal output from the microphone 96 in parallel with the photographing. Then, when a predetermined sound (for example, a phrase such as “shooting”) is recognized, the image data is transmitted to the image management apparatus 20.

(5) When a predetermined time has elapsed since the previous transmission The control unit 93 of the fixed camera 90 counts the time that has elapsed since the last transmission of image data to the image management apparatus 20. Then, when a predetermined time (for example, 10 seconds) has elapsed, the image data is transmitted to the image management apparatus 20.

  According to the image management system according to the second embodiment described above, the following operational effects can be obtained.

(1) A fixed camera 90, which is a fixed imaging device fixed in advance at a predetermined position, is provided. Since it did in this way, an image user's image data can be ensured reliably even in an area without a photographer.

  The following modifications are also within the scope of the present invention, and one or a plurality of modifications can be combined with the above-described embodiment.

(Modification 1)
One visitor 50 can also serve as a photographer and an image user. Such a visitor 50 obtains image data provided by another photographer from the image management apparatus 20 while providing image data captured by the camera 40 to the image management apparatus 20.

(Modification 2)
The image management apparatus 20 may give the photographer an incentive for photographing. For example, as many points as the number of image data to be provided to the image management apparatus 20 may be given, and a prize corresponding to the points may be given, or an entrance fee may be discounted according to the points. The numerical value of the point may be stored in the photographer database 100 in association with the photographer ID 101. Further, points may be given not by the number of image data but by the number of image data acquired by the image user. Since the image database 120 stores the camera ID 122 of the camera 40 that captured the image data 123 with respect to the image data 123, the photographer ID 101 of the photographer who captured the image data 123 can be easily identified. Is possible. In this way, it is possible to receive image data more actively from the photographer.

(Modification 3)
The image management apparatus 20 may request the image user for consideration (for example, a predetermined fee) for image user registration. Moreover, you may request | require consideration for acquisition of a picked-up image instead of image user registration. In combination with the above-described modified example 2, the consideration for image user registration may be “providing a photographed image as a photographer”. In this case, in order for the attendant 50 to obtain a captured image of himself / herself from the image management apparatus 20, the photographed image of another attendee 50 must be provided to the image management apparatus 20 as a photographer. . By doing in this way, provision and acquisition of a picked-up image can be promoted.

(Modification 4)
The fixed camera 90 may include a photographing optical system 91 (so-called zoom lens) having a variable focal length. The fixed camera 90 automatically drives the zoom lens to the wide-angle side, for example, when there is a person whose whole body does not enter the shooting screen.

(Modification 5)
The fixed camera 90 does not necessarily have to be fixedly installed. For example, an imaging device that autonomously travels within the theme park 10 using wheels or the like may be used.

(Modification 6)
An image user may be able to acquire image data in the theme park 10. For example, the information terminal 70 may be installed in a store or the like in the theme park 10, or a tablet terminal that functions as the information terminal 70 may be lent to the visitors 50. Alternatively, the mobile terminal 80 described above may function as the information terminal 70. By doing so, the convenience of the system is improved, for example, image data can be searched during a waiting time at a store or the like in the theme park 10.

  As long as the characteristics of the present invention are not impaired, the present invention is not limited to the above-described embodiments, and other forms conceivable within the scope of the technical idea of the present invention are also included in the scope of the present invention. .
