<Description of FIG. 3>

  FIG. 3 is a flowchart showing processing executed by the server 101 according to the embodiment of the present invention.

  The processing of each step shown in steps S301 to S305 is executed by the CPU 201 of the server 101 in accordance with control by a program recorded in the external memory 211 of the server 101.

  First, each network camera (103 to 114) sequentially transmits captured video data to the server 101. In this example, captured video data is transmitted at predetermined time intervals (for example, 1 minute).

  Here, since each network camera stores identification information for identifying the network camera (individual) in the memory, each network camera stores not only video data but also each memory. The identification information is transmitted to the server 101.

  Then, the server 101 receives video data from each network camera and identification information for identifying the network camera from each network camera (S301).

  Here, the video data includes not only still image data but also moving image data. Similarly to the still image data, the frame image data constituting the moving image data can be a target of processing to be described later.

  Step S301 is an application example of an acquisition unit that sequentially acquires image data (video data) continuously captured by each camera with the passage of time from each camera.

  Then, the server 101 analyzes the video data received in S301, and acquires identification information for identifying the subject (S302). For example, the server 101 identifies the color code attached to the subject from the received video data, and reads and analyzes the identified color code, thereby identifying information (color) for identifying the subject. The code ID (identification information for identifying an individual)) is acquired. By acquiring this identification information, the user who has taken the image can be specified.

  That is, step S301 is an application example of a user specifying unit that specifies a user photographed in the image data by analyzing the image data acquired by the acquiring unit.

Next, the server 101 specifies the area of the network camera (the area where the subject is located) according to the identification information of the network camera received in step S301 and the correspondence table shown in FIG.
<Description of FIG. 11>

  FIG. 11 is a diagram illustrating an example of a correspondence table in which identification information of a network camera is associated with an area name of an area where the network camera is arranged.

  In the table of FIG. 11, area information (area name) indicating an area where a camera is installed is stored in a storage unit (memory) for each camera.

  The correspondence table shown in FIG. 11 includes identification information (001, 002, 003,...) Of each network camera and area names (area A, area B, area C) where each network camera is installed. ,...) Are associated with each other in advance and registered in the memory.

  For example, the area in which the network camera having the network camera identification information 001 is installed is area A.

  In step S303 in FIG. 3, by acquiring the area name stored in the correspondence table (FIG. 11) corresponding to the network camera identification information received in step S301, the area where the network camera is installed is determined. Identify.

  That is, in step S303, based on the area information (FIG. 11) indicating the area where the camera acquired in step S301 is the image data specified in step S302, the area in which the user is specified in step S302. This is an application example of the area specifying means for specifying.

  The server 101 then identifies the area name of the area identified here, identification information for identifying the subject (color code ID (identification information for identifying an individual)) acquired in step S302, Each time (current time) is associated and registered in the management table shown in FIG. 8 or FIG. 9 (S303).

In step S303, the area information indicating the area where the user (parent) specified in step S302 is specified, and the user specified in step S302 specified in step S303 are led by the user. This is an application example of storage means for storing area information indicating an area where another user (child) is present in each memory (storage means) for each shooting time when the image data was shot by the camera.
<Description of FIGS. 8 and 9>
FIG. 8 is a diagram illustrating an example of the management table.
FIG. 9 is a diagram illustrating another example of the management table.

  The management tables shown in FIGS. 8 and 9 are configured by associating items of “ID”, “family ID”, “guardian flag”, “notification destination”, and “time”.

  “ID” is identification information (color code ID) (for example, 100) for identifying the subject.

“Family ID” is an ID (for example, 1) for identifying a group such as a family. Here, subjects (persons) in which the same value is stored indicate that they are the same family (group).

  The “guardian flag” is a flag indicating whether or not the person is a guardian. Here, “1” indicates that the person is a guardian, and “0” indicates that the person is not a guardian (for example, a child).

  “Notification destination” stores information of a notification destination. Here, as the notification destination, for example, an e-mail address (for example, aaa@a.ne.jp) that can be distributed to the guardian's portable terminal 102 is stored.

  In the item of “time”, time (..., “10:55”, “10:56”, “10:57”, “10:58”, “10: 59 ”,“ 11:00 ”(current time)) are provided as items, and at each time, the area name of the area where the subject identified by“ ID ”(for example, 100) was stored is stored. Yes.

  The subject (person) whose “ID” is 100 in FIG. 8 will be described as an example. In FIG. 8, the subject (person) whose “ID” is 100 is the same family (person) as the subject (person) whose “ID” is 101. Group) and a guardian (a subject (person) whose ID is 101 is not a guardian (child)), and a notification destination is aaa @ a. ne. jp, “10:55” in area F, “10:56” in area E, “10:57” in area D, “10:58” in area C It indicates that the user was in Area B at “10:59”, and was in Area A at “11:00” (current time).

  The “ID”, “family ID”, “guardian flag”, “notification destination”, and “time” shown in FIG. 8 or FIG. 9 are registered in advance, and in step S303, the “ID” acquired in step S302. "(Area name of the area identified in step S303 is registered in a column in which identification information (color code ID) for identifying a subject is associated with the current time (current time)).

  In this manner, the server 101 generates the management table shown in FIG. 8 or 9 by updating and registering the management table shown in FIG. 8 or 9 every predetermined period (for example, 1 minute). .

  Next, the server 101 executes the lost child alert process shown in FIG. 4 or the lost child alert process shown in FIG. 5 (step S304). Further, in step S304, the server 101 processes the exit vicinity alert process shown in FIG. 6 and the child leaving alert process shown in FIG. 7 in parallel.

  That is, the server 101 processes the lost child alert process shown in FIG. 4 or the lost child alert process shown in FIG. 5, the exit vicinity alert process shown in FIG. 6, and the child leaving alert process shown in FIG.

When the server 101 executes the process of step S304, the server 101 determines whether or not an administrator (user) has received an end instruction. If the server 101 determines that an end instruction has been received (YES), the server 101 ends the process. If it is determined that the end instruction has not been received (NO), the process returns to step S301.
<Description of FIG. 4>

  Next, detailed processing of the lost child alert processing executed in step S304 shown in FIG. 3 will be described with reference to FIG.

  FIG. 4 is a diagram illustrating an example of a detailed process of the lost child alert process executed in step S304 illustrated in FIG.

The processing of each step shown in steps S401 to S404 is executed by the CPU 201 of the server 101 in accordance with control by a program recorded in the external memory 211 of the server 101.
The flowchart shown in FIG. 4 is repeatedly executed for each identical family ID.

  First, the server 101 executes the process shown in FIG. 4 for each identical family ID in order from the top record at the top of the management table (FIG. 8 or FIG. 9).

First, the server 101 stores, from the management table (FIG. 8 or FIG. 9), data “ID”, “family ID”, “guardian flag”, “notification destination” among records having the same family ID, The area name of the current time and the area name for a predetermined time (for example, 6 seconds here) from the current time are acquired (step S401).
For example, a record in which “family ID” is 1 is described as an example.

  In step S401, among the records with “ID” of 100 and 101, information with “ID” of 100 (“ID” is 100, “family ID” is 1, “guardian flag” is 1, and “notification destination” is “notification”). aaa@a.ne.jp, area when "10:55": Area F, area when "10:56": Area E, area when "10:57": Area D, "10:58" area: Area C, "10:59" area: Area B, "11:00" area: Area A), and "ID" is 101 Information (“ID” is 101, “family ID” is 1, “guardian flag” is 0, “notification destination” is NULL, “10:55” area: area F, “10:56” When we were: Area E, “10:57” Area: acquisition area B, and area B) of "11:00", a: area D, the area was in when the "10:58": area C, the area was in when the "10:59".

  Then, the server 101 determines whether or not the area where the current parent and child are located is different according to the area name of the current time of the parent and child acquired in step S401 (S402).

  For example, the area name at the current time (11:00) where the guardian flag is set to 1 is compared with the area name at the current time (11:00) where the guardian flag is set to 0, and the same If it is, it is determined that the parent and child are in the same area (NO). On the other hand, if they are not the same, it is determined that the parent and child are not in the same area (the area where the current parent and child are present is different) (YES).

  If the server 101 determines in step S402 that the parent and child are in the same area (NO), the server 101 proceeds to step S305, and if it is determined that the parent and child are in different areas (YES), The process proceeds to step S403.

  Then, the server 101 has parents and children for the most recent predetermined period (for example, 2 seconds) among the area names of the parent and child for a predetermined time (for example, 6 seconds here) from the current time acquired in step S401. It is determined whether the areas are different (step S403).

  For example, in step S403, the area name at the time (10:58) when the guardian flag is set to 1 matches the area name at the time (10:58) when the guardian flag is set to 0. And the area name at the time (10:59) at which the guardian flag is set to 1 matches the area name at the time (10:59) at which the guardian flag is set to 0. It is determined whether or not.

  In the server 101, the area name at the time (10:58) when the guardian flag is set to 1 matches the area name at the time (10:58) when the guardian flag is set to 0. And the area name at the time (10:59) when the guardian flag is set to 1 matches the area name at the time (10:59) when the guardian flag is set to 0. If it is determined, it is determined that the area where the parent and child are in the last predetermined period (for example, 2 seconds) is not different (the area where the parent and child are the same) (NO), while the guardian flag is set to 1. The area name at the current time (10:58) does not match the area name at the time (10:58) when the guardian flag is set to 0, or the guardian flag is set to 1 Area name (10:59) If it is determined that the area name at the time (10:59) at which 0 is set to 0 does not match, the area where the parent and child are in the latest past predetermined period (for example, 2 seconds) is different (YES) ).

  Steps S402 and S403 are the past from the last shooting time (for example, 11:00 (current) in FIG. 8) when the area information specified in step S303 (area specifying means) is stored in the memory (storage means). Area information (area name) indicating the area where the parent (user) is stored and area information (area name) indicating the area where the child (other user) is stored in step S303 (storage means) within the predetermined time It is an application example of the determination means which determines whether each is different.

If it is determined in step S403 that the parent and child areas of the most recent past predetermined period (for example, 2 seconds) are different (YES), the server 101 indicates that the child is lost with the same family ID. Notification is made to a notification destination (for example, aaa@a.ne.jp) whose flag is set to 1.
An example of the content notified here is shown at 1001 in FIG.

  For example, when the family ID in FIG. 8 is 1, the travel route of the parent (parent) (guardian flag is 1) and the child (guardian flag is 0) is the same from 10:55 to 10:59. However, at 11:00, the area where the parent and child are located is different.

  Thus, even if the area where the parent and the child are different at the current time, the area where the parent and the child are the same within the predetermined period immediately after the current time is determined as NO in S403, The parent is not notified that the child is lost.

  Therefore, for example, even when the parent moves to an area different from that of the child at the update timing of the management table, it is possible to reduce erroneous determination that the child is lost.

  In this way, by performing the processing shown in FIG. 4, for example, when the color code cannot be recognized temporarily due to an obstacle, or when the parent and child are moving together, Even if it is recognized that the user is in a different area, the misjudgment of the lost child can be reduced.

  Also, for example, as in the case of family ID 4 in FIG. 8, when the color code cannot be captured due to an obstacle or the like and the area where the parent or child is present cannot be recognized (when the current area is NULL) ), It is possible to reduce erroneous determination that the child is lost because the child is not notified that the child is lost.

  Thus, taking the management table shown in FIG. 8 as an example, when the lost child alert process shown in FIG. 4 is executed, for the family IDs 1 and 4, the parent is not notified that the child is lost, but the family ID In the case of 2 or 3, the parent is notified that the child is lost.

  However, if the walking speed of the child is slower than the walking speed of the parent, and if the parent happens to be in an area ahead of the area where the child is, the parent / child is as in the case where the family ID in the management table shown in FIG. May be detected.

That is, in the case of the process of FIG. 4, the parent / child route is the same, but even when the parent / child area at each time is different, the parent is notified that the child is lost. A mechanism for reducing such erroneous determination will be described later with reference to FIG.
<Description of FIG. 10>
FIG. 10 is a diagram illustrating an example of notification contents notified by the server 101.

  At 1001 in FIG. 10, the child is lost and the position of the network camera where the child is currently photographed is notified as the current location where the child is.

  If the server 101 determines in step S403 that the parent and child areas of the most recent past predetermined period (for example, 2 seconds) match (NO), the server 101 proceeds to processing step S305.

The server 101 can also execute the lost child alert process shown in FIG. 5 instead of the lost child alert process shown in FIG.
<Description of FIG. 5>

  Next, detailed processing of the lost child alert processing executed in step S304 shown in FIG. 3 will be described with reference to FIG.

  FIG. 5 is a diagram illustrating an example of a detailed process of the lost child alert process executed in step S304 illustrated in FIG.

The processing of each step shown in steps S401 to S404, S405, and S406 shown in FIG. 5 is executed by the CPU 201 of the server 101 according to control by a program recorded in the external memory 211 of the server 101.
The flowchart shown in FIG. 5 is repeatedly executed for each identical family ID.

First, the server 101 executes the process shown in FIG. 5 for each identical family ID in order from the top record at the top of the management table (FIG. 8 or FIG. 9).
In FIG. 5, steps that perform the same processing as in FIG.
Therefore, in FIG. 5, only processing different from that in FIG. 4 will be described.

  The flowchart shown in FIG. 5 is different from the flowchart shown in FIG. 4 only in that step S405 and step S406 are added.

  If the server 101 determines in step S403 that the parent and child areas in the most recent predetermined period (for example, 2 seconds) are different (step S403: YES), the server 101 obtains each time of the parent and child acquired in step S401. From the area name, the movement path for a predetermined time (for example, 5 seconds) of each parent and child is specified (step S405).

In step S405, area information (area name) indicating the area where the parent (user) is stored, area information (area name) indicating the area where the child (other user) is stored, stored in step S303 (storage means) ( 8 or 9), the last shooting time (for example, FIG. 8) in which the area information (area name) specified by step S303 (area specifying means) is stored in the memory (storage means) by step S304 (storage means). 8: 11:00 (current)) within a predetermined time in the past, this is an application example of specifying means for specifying the movement route of the parent (user) and the movement route of the child (other users).
Here, a specific example of step S405 will be described.

  For example, when the record having the family ID 2 shown in FIG. 8 (the record with the color code ID 102 and the record with the color code ID 103) is acquired in step S401 and is the processing target, the color code ID is The subject (person) of 102 moves in the area F (10:56), area E (10:57), area D (10:58), area C (10:59), and area B (11:00). The subject (person) whose color code ID is 103 is area F (10:55), area E (10:56), area D (10:57), and area C (10: 58), the area is moved along the movement route of area B (10:59). That is, a subject (person: parent) with a color code ID of 102 and a subject (person: child) with a color code ID of 103 are moving on the same movement path with a shift of one minute.

  As described above, in step S405, it is possible to specify a movement path for a predetermined time (for example, 5 seconds) of each parent and child from the area name obtained at each time of the parent and child acquired in step S401.

  Next, the server 101 determines whether or not the movement paths for a predetermined time (for example, 5 seconds) of the parent and child specified in step S405 are different (step S406). If it is determined that they are different (YES) ) To notify that the child is lost (step S404). On the other hand, when it is determined that the movement paths for a predetermined time (for example, 5 seconds) of the parent and child are the same (NO), the process proceeds to step S305 without notifying that the child is lost. Since step S404 is the same process as step S404 in FIG. 4, the description thereof is omitted here.

  Step S406 is an application example of the movement path determination means for determining whether or not the movement path of the parent (user) specified in step S405 (specification means) is different from the movement path of the child (other user). .

  In step S404, area information (area name) indicating an area where a parent (user) is present and area information (area name) indicating an area where a child (other user) is present are determined by steps S402 and S403 (determination means), respectively. When it is determined that they are different, and it is determined by step S406 (movement path determination means) that the movement path of the parent (user) is different from the movement path of the child (other user) (step S406: YES). The server 101 controls to notify the terminal operated by the parent or the administrator that the child (other user) is lost (control means).

  Further, step S402 and step S403 (determination means) match the area information (area name) indicating the area where the parent (user) is present with the area information (area name) indicating the area where the child (other user) is present. (Step S402: NO, Step S403: NO) Or, by Steps S402, S403 (determination means), the area information (area name) indicating the area where the parent (user) is present and the area where the child (other user) is present Even when it is determined that the area information (area name) shown is different from each other, the parent (user) movement path and the child (other user) movement path are determined by step S406 (movement path determination means). Are determined to match (step S406: NO), the server 101 does not notify that the child (other user) is lost. To control (control means).

  In step 404, the server 101 indicates that the child (other user) is lost, and the area information (area name) of the other user is stored in the memory (storage unit) by step S303 (storage unit). The area information (area name) of the other user (child) at the last shooting time (for example, 11:00 in FIG. 9 (current)) is notified.

Thus, in addition to the above-described effects of the process shown in FIG. 4, the process shown in FIG. 5 actually causes the parent and child to move together. However, if the parent and child happen to be in different areas, the process continues. Even if it is recognized, it is possible to reduce the number of misidentifications of lost children.
<Description of FIG. 6>

  Next, the detailed process of the exit vicinity alert process executed in step S304 illustrated in FIG. 3 will be described with reference to FIG.

  FIG. 6 is a diagram showing an example of a detailed flowchart of the exit vicinity alert process executed in step S304 shown in FIG.

The processing of each step shown in steps S601 to S609 is executed by the CPU 201 of the server 101 in accordance with control by a program recorded in the external memory 211 of the server 101.
The flowchart shown in FIG. 6 is repeatedly executed for each identical family ID.

  First, the server 101 executes the process shown in FIG. 6 for each identical family ID in order from the top record at the top of the management table (FIG. 8 or FIG. 9).

  First, similarly to step S401, the server 101 selects “ID”, “family ID”, “guardian flag”, “notification destination” from the management table (FIG. 8 or FIG. 9), among records having the same family ID. ”, The area name at the current time, and the area name for a predetermined time (for example, 6 seconds here) from the current time (step S601).

  Then, the server 101 determines whether or not the area where the current parent and child are located is different according to the area name of the current time of the parent and child acquired in step S601 (S602).

  Since the process of step S602 is the same process as step S402 described above, a description using a specific example is omitted here.

  If it is determined in step S602 that the parent and child are in the same area (NO), the server 101 proceeds to step S305, and if it is determined that the parent and child are in different areas (YES), The process proceeds to step S603.

  Then, the server 101 has the parent and child for the most recent predetermined period (for example, 2 seconds) among the area names of the parent and child for the predetermined time (for example, 6 seconds here) acquired from the current time acquired in step S601. It is determined whether the areas are different (step S603).

  Since the process of step S603 is also the same process as step S403 described above, a description using a specific example is omitted here.

  If the server 101 determines in step S603 that the parent and child areas of the latest past predetermined period (for example, 2 seconds) are different (YES), the server 101 proceeds to step S604. On the other hand, if it is determined that the parent-child areas in the most recent past predetermined period (for example, 2 seconds) are not different (same) (NO), the process proceeds to step S608.

  If the server 101 determines in step S603 that the area where the parent and child are in the most recent past predetermined period (for example, 2 seconds) is different (step S603: YES), the server 101 acquires each time of the parent and child acquired in step S601. From the area name, the movement path for a predetermined time (for example, 5 seconds) of each parent and child is specified (step S604).

  Since step S604 is also the same process as step S405 described above, a description using a specific example is omitted here.

  Then, the server 101 determines whether or not the movement paths for a predetermined time (for example, 5 seconds) of the parent and child specified in step S604 are different (step S605). If it is determined that they are different (YES) The process proceeds to step S606. On the other hand, if it is determined that the movement paths for a predetermined time (for example, 5 seconds) of the parent and child are the same (NO), the process proceeds to step S608.

  Since step S605 is the same process as step S406 of FIG. 5, the description using a specific example is omitted here.

  In step S606, the server 101 determines from the area name acquired in step S601 whether or not the current parent area is not the exit area or the vicinity of the exit, but the child is in the exit area or the vicinity of the exit. .

  For example, when a record with a family ID of 3 (a record with an ID of 104 and a record with an ID of 105) shown in the management table 900 of FIG. 9 is a processing target, the determination process in step S606 is performed. In this case, 11:00 (current), the parent (subject with ID 104) is in area A, and the child (subject with ID 105) is in area C (exit area or near the exit). I understand that.

  Therefore, if the family ID shown in the management table 900 of FIG. 9 is a record of 3, in step S606, the parent area is not the exit area or the vicinity of the exit, but the child is in the exit area or the vicinity of the exit ( Step S606: YES) is determined.

The server 101 determines from the area name acquired in step S601 that the current parent area is not the exit area or the vicinity of the exit, and that the child is in the exit area or the vicinity of the exit (step S606: (Yes), Notify the notification destination of the record in which the guardian flag of the record to be processed is set to 1 that the child is lost and the child may go out of the facility (step) S607).
An example of the content notified in step S607 is shown in 1002 of FIG.

  And the server 101 will transfer a process to step S305, if the process of step S607 is performed.

  In step S606, the server 101 determines from the area name acquired in step S601 that the current parent area is the exit area or the vicinity of the exit, or that the child is not in the exit area or the vicinity of the exit. If so (step S606: NO), the process proceeds to step S305.

  In step S608, the server 101 determines from the area name acquired in step S601 whether the area where the parent is currently is not the exit area or the vicinity of the exit, and the child is in the exit area or the vicinity of the exit. .

  Since the process in step S608 is the same as the process in step S606, a description using a specific example is omitted here.

  In step S608, the server 101 determines from the area name acquired in step S601 that the current parent area is not the exit area or the exit vicinity area, and that the child is in the exit area or the exit vicinity area. If yes (YES), the fact that there is a possibility that the child may go out of the facility is notified to the notification destination of the record in which the guardian flag of the record to be processed is set to 1 (step S609).

  An example of the content notified in step S609 is shown in 1003 of FIG. And the server 101 will transfer a process to step S305, if the process of step S607 is performed.

  In step S608, the server 101 determines that the area where the parent is currently is the exit area or the vicinity of the exit from the area name acquired in step S601, or the child is not in the exit area or the vicinity of the exit. (NO), the process proceeds to step S305.

  In steps S606 and S608, the area information (area name) of the parent (user) at the last shooting time (for example, 11:00 (current) in FIGS. 8 and 9) in the table of FIG. Whether the area information (area name) of the child (other user) is area information (area C) indicating the exit area or the vicinity of the exit, not the area information (area C) indicating the exit area or the vicinity of the exit. It is an example of application of the exit determination means for determining.

  In step S607 and step S609, the server 101 notifies that other users will leave the facility.

  By executing the processing shown in FIG. 6, when the area where the parent is not the exit area and the area where the child is located is the exit area, for example, the child goes out of the facility to notify the guardian of an alert. Therefore, it is possible to prevent the color code search from being disabled.

  Furthermore, if the child is lost and has come to the exit area (YES in S602, YES in S603, YES in S605, YES in S606), the child is lost in step S607. In order to notify parents of the fact that the child is going out of the facility, the child who is lost is out of the facility while the parent is inside the facility, making it impossible to search by color code. Can be prevented.

  If the parent and child are moving together, but it happens that the parent and child are recognized to be in different areas (NO in S604 and S605), the notification that the child is lost is not performed in S607. Therefore, misjudgment of a lost child can be prevented.

Further, although the parent and child are moving together, even if it is recognized that the parent and the child are in different areas (NO in S604 and S605), the parent is not in the exit area in step S608. If it is determined that the child is in the exit area (YES), for example, in order to notify that the child will go out of the facility, for example, the child was not lost, but the child suddenly headed for the exit If you run away from your parents and your child is about to leave the facility from the exit, you can see that your child is in the exit area. It is possible to prevent the child from leaving.
<Explanation of FIG. 7>

  Next, the detailed process of the child leaving alert process executed in step S304 shown in FIG. 3 will be described with reference to FIG.

  FIG. 7 is a diagram showing an example of a detailed flowchart of the child leaving alert process executed in step S304 shown in FIG.

The processing of each step shown in steps S701 to S707 is executed by the CPU 201 of the server 101 in accordance with control by a program recorded in the external memory 211 of the server 101.
The flowchart shown in FIG. 7 is repeatedly executed for each identical family ID.

  First, the server 101 executes the process shown in FIG. 7 for each identical family ID in order from the top record at the top of the management table (FIG. 8 or FIG. 9).

  First, similarly to step S401, the server 101 selects “ID”, “family ID”, “guardian flag”, “notification destination” from the management table (FIG. 8 or FIG. 9), among records having the same family ID. ”, The area name at the current time, and the area name for a predetermined time (for example, 6 seconds here) from the current time (step S701).

  Since the process in step S701 is the same as that in step S401 described above, a description using a specific example is omitted here.

  Then, the server 101 determines whether or not the area where the current parent and child are located is different according to the area name of the current time of the parent and child acquired in step S701 (S702).

  Since the process of step S702 is the same process as step S402 described above, a description using a specific example is omitted here.

  If it is determined in step S702 that the parent and child are in the same area (NO), the server 101 proceeds to step S305, and if it is determined that the parent and child are in different areas (YES), The process proceeds to step S703.

  Then, the server 101 has the parent and child for the most recent predetermined period (for example, 2 seconds) among the area names of the parent and child for the predetermined time (for example, for 6 seconds here) acquired from the current time acquired in step S701. It is determined whether the areas are different (step S703).

  If the server 101 determines in step S703 that the areas with the parent and child for the most recent predetermined period (for example, 2 seconds) are different (YES), the server 101 moves the process to step S704, If it is determined that the areas with the parent and child for a predetermined period (for example, 2 seconds) are not different (is the same) (NO), the process proceeds to step S305.

  Since the process in step S703 is the same as that in step S403 described above, a description using a specific example is omitted here.

  Next, the server 101 determines whether or not the current and the latest past predetermined period (for example, 2 seconds) have been recognized by the parent (step S704). Specifically, it is determined whether or not the area that is the parent for the most recent predetermined period (for example, 2 seconds) among the area names acquired in step S701 is NULL. NULL is a value registered in the management table (FIG. 8 or FIG. 9) when the ID cannot be read from the color code.

  If the server 101 determines that the parent area for the current and the latest past predetermined period (for example, 2 seconds) has been recognized (NULL) (YES), the process proceeds to step S705. On the other hand, if it is determined that the parental area for the present and the latest past predetermined period (for example, 2 seconds) can be recognized (NO), the process proceeds to step S305.

  Next, the server 101 determines whether or not the area where the child is present is an area in the facility (step S705).

  Specifically, by determining whether or not the current area of the record with the guardian flag of 0 acquired in step S701 is NULL, it is determined whether or not the area where the child is currently is an area in the facility. Determine whether.

  If the server 101 determines that the area where the child is present is an area in the facility (the current area of the record with the guardian flag 0 acquired in step S701 is not NULL) (YES), When the process proceeds to step S706, on the other hand, it is determined that the area where the child is present is not an area in the facility (the current area of the record with the guardian flag acquired in step S701 is NULL) In step S305, the process proceeds to step S305.

  In step S706, the server 101 determines whether the latest parent area detected in the past is the exit area. Specifically, among the data of the record with the guardian flag of 1 acquired in step S701, the area name where the parent area is detected is the area C (exit area) at the time closest to the present (most recent). It is determined whether or not there is.

In step S706, the server 101 determines that the parent area detected in the past in the past is the exit area (the area name where the parent is detected is the area C (exit area )) (Step S706: YES), the notification destination of the record with the guardian flag being 1 among the records acquired in step S701 that the child has been left in the facility (Step S707).
An example of the content notified in step S707 is shown in 1004 of FIG.

  Steps S704, S705, and S706 include area information (area) indicating an area where a parent (user) is present within a predetermined past time from the last shooting time (eg, 11:00 (current)) in FIGS. Name) is NULL that does not indicate an area in the facility, and area information (area name) that indicates an area where a child (another user) is in the last shooting time is an area in the facility (other than NULL). The area information (area name) of the parent (user) at the last shooting time indicating the area information (area name) indicating the area in the facility (other than NULL) is the area indicating the exit area or the vicinity of the exit in the facility It is an application example of the leaving determination means for determining whether the information (area C).

  In step S707, notification is made that the child (other user) has been left behind in the facility.

  As described above, by executing the processing shown in FIG. 7, the area where the parent is present is NULL and the area where the child is present is the area in the facility at the present and the latest past predetermined period. If the detected parent area is an exit area, the parent can be notified that the child has been left in the facility.

  Therefore, for example, if a child is left in the facility and the parent leaves the facility, the parent can know that the child has been left in the facility, and the color code is indicated by the obstacle. If the child is temporarily unable to recognize, or if the parent and child are moving together, it happens that the parent leaves the facility first and the child later leaves the facility. It is possible to reduce the determination of leaving behind.

  As described above, according to the present invention, the user and the other user led by the user are moving together, but it is continuously determined that the user and the other user led by the user are in different areas. Even if it happens, it is possible to reduce the erroneous determination that the other user is lost.

  Moreover, according to this invention, it can prevent that a child leaves | separates from a parent and goes out of a facility alone, or a parent leaves a child in a facility and goes out of a facility.
