[Configuration of the flow line management device 4]
Next, the configuration of the flow line management device 4 will be described. FIG. 4 is a diagram illustrating a configuration of the flow line management device 4 according to the first embodiment. The flow line management device 4 includes a communication unit 41, a storage unit 42, and a control unit 43.

The communication unit 41 communicates with the terminal 3 via a communication network such as a wireless LAN (Local Area Network).
The storage unit 42 is a storage medium including a ROM and a RAM. The storage unit 42 stores a program executed by the control unit 43. For example, the storage unit 42 converts the flow line management device 4 into a moving image acquisition unit 431, a speed information acquisition unit 432, a reception history acquisition unit 433, a flow line management unit 434, a removal unit 435, a calculation unit 436, a person identification unit 437, In addition, a flow line management program that functions as the connection unit 438 is stored.

  The storage unit 42 stores user information in which a terminal ID that identifies the terminal 3 possessed by the target person and a user ID that identifies the target person are associated with each other. In addition, the storage unit 42 stores transmitter position information indicating the installation positions of the plurality of transmitters 2.

  The control unit 43 is a CPU, for example. The control unit 43 executes the program stored in the storage unit 42, thereby moving the moving image acquisition unit 431, the speed information acquisition unit 432, the reception history acquisition unit 433, the flow line management unit 434, the removal unit 435, the calculation unit 436, It functions as a person specifying unit 437 and a connecting unit 438.

  The moving image acquisition unit 431 functions as a person position information acquisition unit. The moving image acquisition unit 431 acquires person position information from the photographing apparatus 1 as a generation apparatus that generates person position information indicating the position of the person for each time in the action area via the communication unit 41. Specifically, the moving image acquisition unit 431 acquires moving image information as person position information from the imaging device 1 that captures an action area and generates moving image information at predetermined time intervals. The moving image acquisition unit 431 stores the acquired moving image information in the storage unit 42. Here, the moving image information includes a plurality of photographed images, and the plurality of photographed images are associated with photographing times that are times when the photographed images are photographed.

  In the present embodiment, the moving image acquisition unit 431 acquires the moving image information from the photographing apparatus 1, but the present invention is not limited to this. In the action area, a rider (LIDAR: light detection and ranging) that specifies the position of a surrounding object is installed instead of the photographing device 1, and the control unit 43 determines the position of the surrounding object detected by the rider at each time. The information shown may be acquired as person position information.

  The speed information acquisition unit 432 acquires speed information generated in the terminal 3 from each of the plurality of terminals 3 via the communication unit 41. The speed information acquisition unit 432 stores the acquired speed information in the storage unit 42.

  The reception history acquisition unit 433 acquires the reception history information generated in the terminal 3 from each of the plurality of terminals 3 via the communication unit 41. The reception history acquisition unit 433 causes the storage unit 42 to store the acquired reception history information.

  The flow line management unit 434 specifies a flow line indicating the movement locus of the person in the action area based on the moving image information as the person position information acquired by the moving image acquisition unit 431. Specifically, first, the flow line management unit 434 analyzes a plurality of captured images included in the moving image information stored in the storage unit 42 to identify a person shown in each of the plurality of captured images. To do. In addition, the flow line management unit 434 specifies the position of the person in the action area based on the position of the person in the captured image. For example, the flow line management unit 434 specifies coordinate information indicating the position of the person in the action area. The flow line management unit 434 specifies the position of the person at each time in the action area by specifying the person shown in each of the plurality of captured images and the position of the person. The flow line management unit 434 specifies the positions of a plurality of persons for each time in the action area.

  Based on the position of the person at each specified time, the flow line management unit 434 generates flow line information that associates information related to the time with position information indicating the position of the person at the time, thereby Identify the flow line. The flow line management unit 434 associates the positions of the two persons, assuming that the persons at the two times are the same person when the positions of the persons at two adjacent times are within a predetermined distance. The flow line management unit 434 generates flow line information by associating the positions of persons at all two adjacent times. The flow line management unit 434 specifies the flow lines of each of a plurality of persons in the action area.

  The removal unit 435 performs a removal process of removing position information generated when the person is hardly moving from the flow line information generated by the flow line management unit 434. Specifically, the removing unit 435 calculates the distance from the position indicated by the predetermined position information in order from the position information corresponding to the time closest to the time corresponding to the predetermined position information included in the flow line information. The position information whose distance is less than the predetermined distance is removed from the position information used for calculating the movement distance by the calculation unit 436.

  FIG. 5 is a flowchart showing a flow of processing corresponding to the removal processing performed by the removal unit 435 according to the first embodiment. First, the removal unit 435 sets the start position of the flow line indicated by the flow line information as the reference position (S51). Here, the start position of the flow line is the position indicated by the position information associated with the oldest time among the times included in the flow line information.

  Subsequently, the removing unit 435 specifies the next position after the specified position (S52). Specifically, the removal unit 435 specifies the position indicated by the position information associated with the time next to the time associated with the position information indicating the identified position as the next position.

Subsequently, the removing unit 435 calculates the distance between the identified position and the reference position as the movement distance corresponding to these two positions of the person corresponding to the flow line (S53).
Subsequently, the removing unit 435 determines whether or not the moving distance is less than a predetermined distance (S54). If the removal unit 435 determines that the moving distance is less than the predetermined distance, it moves the process to S55, and if it determines that the moving distance is greater than or equal to the predetermined distance, it moves the process to S56.

In S55, the removal unit 435 removes the position information corresponding to the position specified in S52 and the time information associated with the position information from the flow line information.
In S56, the removal unit 435 sets the position specified in S52 as a new reference position.

  In S57, the removal unit 435 determines whether or not the position specified in S52 is the end position of the flow line indicated by the flow line information. If the removal unit 435 determines that the specified position is the end position of the flow line, the removal unit 435 ends the process according to this flowchart, and if it is determined that the specified position is not the end position of the flow line, moves the process to S52.

  By doing in this way, the flow line management device 4 can remove the position information generated by being regarded as moved even though the person has not moved from the flow line information. The calculation accuracy of the movement distance of the person by 436 can be improved.

  The calculation unit 436 calculates the movement distance of the person indicated by the flow line specified by the flow line management unit 434. Specifically, the calculation unit 436 refers to the flow line information corresponding to the flow line, and based on the position information that is not removed by the removal unit 435, the calculation unit 436 calculates the two positions indicated by the two position information adjacent to each other. By calculating the total distance, the movement distance of the person indicated by the flow line is calculated.

  The person specifying unit 437 specifies a target person corresponding to each of the specified plurality of flow lines. When the movement distance calculated by the calculation unit 436 is equal to or greater than the first distance, the person specifying unit 437 specifies a target person corresponding to the flow line based on the flow line pattern of the person indicated by the flow line. Here, the flow line pattern is, for example, a time-series change of position information included in the flow line information.

  Specifically, when the movement distance calculated by the calculation unit 436 is greater than or equal to the first distance, the person specifying unit 437 determines each of the plurality of terminals 3 indicated by the plurality of speed information acquired by the speed information acquisition unit 432. A target person corresponding to the flow line is specified based on the movement speed and the movement speed of the person indicated by the flow line.

  More specifically, the person specifying unit 437 calculates the speed at each time of the person indicated by the flow line based on the time indicated by the time information included in the flow line information and the position indicated by the position information. The person specifying unit 437 calculates the similarity between the speed of the person indicated by the flow line at each time and the speed of the terminal 3 at each time indicated by the speed information corresponding to the time zone corresponding to the flow line. The terminal ID included in the speed information having the highest degree is specified. Then, the person specifying unit 437 specifies the target person corresponding to the flow line by referring to the user information stored in the storage unit 42 and specifying the user ID associated with the specified terminal ID. The person specifying unit 437 stores the specified user ID in association with the flow line information corresponding to the flow line stored in the storage unit 42.

  In addition, when the movement distance calculated by the calculation unit 436 is less than the first distance, the person specifying unit 437 specifies the position where the person is staying based on the flow line. And the person specific | specification part 437 is based on the reception log information acquired from the transmitter 2 installed in the position relatively close to the specified position among the several reception log information which the reception log | history acquisition part 433 acquired. The target person corresponding to the flow line is specified.

  Specifically, first, the person specifying unit 437 specifies the position where the person stays based on the position information indicated by the flow line information. When the movement distance calculated by the calculation unit 436 is less than the first distance, it indicates that the person hardly moves and stays at a specific position. Therefore, the person specifying unit 437 specifies the center of the position indicated by the plurality of pieces of position information included in the flow line information as the position where the person is staying. In addition, the person specifying unit 437 specifies the time zone in which the person is staying based on the time indicated by the flow line information.

  Subsequently, the person identifying unit 437 refers to the transmitter location information stored in the storage unit 42, identifies the transmitter 2 closest to the identified location, and identifies the beacon ID of the transmitter 2. Subsequently, the person specifying unit 437 specifies the terminal ID of the terminal 3 that has received a relatively large number of the specified beacon IDs in the specified time zone among the plurality of reception history information acquired by the reception history acquiring unit 433. . For example, the person specifying unit 437 calculates the number of reception times of the specified beacon ID in the specified time zone for each terminal ID included in the extracted reception history information.

  Further, based on the extracted reception history information, the person specifying unit 437 specifies the terminal ID of the terminal 3 having a relatively high radio wave intensity associated with the specified beacon ID in the specified time zone. For example, the person specifying unit 437 calculates the average value of the radio field intensity associated with the specified beacon ID in the specified time zone for each terminal ID included in each of the plurality of reception history information.

And person specific part 437 calculates evaluation value V based on the following formula (1) for every terminal ID. Here, Ravg is the average value of the radio field intensity, and Nr is the number of times the beacon ID is received. Nt is the theoretical number of reception times of the beacon ID of the terminal 3 in the time period specified by the person specifying unit 437.
V = (− Ravg * (Nt * 2−Nr)) (1)

  The person specifying unit 437 specifies the terminal ID corresponding to the smallest evaluation value V among the evaluation values V calculated for each terminal ID as the terminal ID of the terminal 3 possessed by the person corresponding to the flow line. And the person specific | specification part 437 refers to the user information memorize | stored in the memory | storage part 42, By specifying the user ID linked | related with the identified terminal ID, the target person linked | related with the said terminal ID is identified. Identify. The person specifying unit 437 stores the specified user ID in association with the flow line information corresponding to the flow line stored in the storage unit 42.

  When the person specifying unit 437 specifies a target person based on the reception history information, the terminal 3 of the terminal 3 that has not moved relatively in the specified time zone based on the acceleration information included in the reception history information An ID may be specified, and a target person corresponding to the terminal ID may be specified as a target person corresponding to the specified flow line. By doing in this way, the flow line management apparatus 4 can improve the identification accuracy of the target person when specifying the target person based on the reception history information. In addition, the person specifying unit 437 may specify a target person corresponding to the flow line based on the number of times the beacon ID is received in the specified time zone, the radio wave intensity, and the acceleration of the terminal 3.

  In addition, since the flow line with a long movement distance has more information indicating the speed change at each time than the flow line with a short movement distance, the target person can be specified with high accuracy. Therefore, when the flow line management unit 434 identifies a plurality of flow lines with overlapping time zones, the person specifying unit 437 starts from a flow line having a long movement distance calculated by the calculation unit 436 among the plurality of flow lines. In order, the target person corresponding to the flow line may be specified so as not to overlap with other flow lines.

  FIG. 6 is a diagram illustrating an example in which the person specifying unit 437 according to the first embodiment specifies a target person in order from a flow line having a long moving distance. As shown in FIGS. 6A to 6C, it is assumed that the flow lines L1 to L3 are specified. Here, it is assumed that the movement line L1 has a longer movement distance than the movement line L2, and the movement line L2 has a longer movement distance than the movement line L3. In addition, the flow lines L1 to L3 are assumed to have overlapping time zones. Further, it is assumed that target persons P1 to P5 exist.

  In this case, the person specifying unit 437 specifies the target person corresponding to the flow line L1 having the longest moving distance from the target persons P1 to P5. Here, it is assumed that the person specifying unit 437 specifies the target person P1 as the target person corresponding to the flow line L1.

  Subsequently, the person specifying unit 437 specifies a target person corresponding to the flow line L2 having the second longest moving distance. In this case, the person specifying unit 437 specifies the target person corresponding to the flow line L2 from the target persons P2 to P5 excluding the target person P1 already specified as the target person corresponding to the flow line L1. Here, it is assumed that the person specifying unit 437 specifies the target person P3 as the target person corresponding to the flow line L2.

  Subsequently, the person specifying unit 437 specifies a target person corresponding to the flow line L3 having the third longest moving distance. Here, the person specifying unit 437 removes the target persons P1, P3, which have already been specified as target persons corresponding to the flow lines L1, L2, and the target person corresponding to the flow line L3 from the target persons P2, P4, P5. Is identified. Here, it is assumed that the person specifying unit 437 specifies the target person P4 as the target person corresponding to the flow line L3. By doing in this way, the flow line management apparatus 4 can further increase the accuracy of specifying the target person and can prevent the same target person from being specified for a plurality of flow lines. .

  Further, when the movement distance calculated for the flow line is equal to or greater than the first distance, the person specifying unit 437 is based on the movement speed of each of the plurality of terminals 3 and the movement speed of the person indicated by the flow line. The target person corresponding to the specified flow line is specified, but the present invention is not limited to this.

  When the movement distance calculated for the flow line is not less than the first distance and less than the second distance, the person specifying unit 437 determines the position where the person stays for a predetermined time or more based on the flow line. You may specify. The person specifying unit 437 includes reception history information corresponding to the transmitter 2 installed at a position relatively close to the specified position, a person's flow line pattern (moving speed) indicated by the flow line, a plurality of The target person corresponding to the flow line may be specified based on the moving speed of each of the terminals 3.

  In this case, the person specifying unit 437 first determines one or more based on the speed information acquired in advance when the movement distance calculated with respect to the flow line is not less than the first distance and less than the second distance. The moving speed of each target person for each time is calculated. Further, the person specifying unit 437 calculates the movement speed of the person corresponding to the flow line for each time based on the flow line information corresponding to the flow line. Subsequently, the person specifying unit 437 calculates the similarity between the moving speed of each of the one or more target persons at each time and the moving speed of the person corresponding to the flow line at each time.

  Subsequently, when the highest similarity among the similarities calculated for each of the one or more target persons is less than a predetermined value, the person specifying unit 437 determines that the person has a predetermined time based on the flow line. The position where the above stays is specified. Subsequently, the person specifying unit 437 specifies a target person corresponding to the flow line based on reception history information corresponding to the transmitter 2 installed at a position relatively close to the specified position.

  As described above, the flow line management device 4 uses the reception history information when the similarity calculated based on the moving speed is low and the target person corresponding to the flow line cannot be accurately identified. The target person corresponding to is identified. Thereby, the flow line management apparatus 4 can specify the target person corresponding to the flow line with higher accuracy than when the target person is specified based only on the moving speed.

  The connection unit 438 connects the same flow lines of the target person specified by the person specifying unit 437 among the plurality of flow lines. The connecting unit 438 refers to the plurality of flow line information associated with the user ID, and connects the plurality of flow line information associated with the same user ID and having continuous time indicated by the flow line information. One flow line information is generated. The connection unit 438 stores the generated flow line information in the storage unit 42. By doing in this way, the flow line management apparatus 4 can manage a several continuous flow line as one flow line.

[Flow of processing in flow line management device 4]
Next, the flow of processing in the flow line management device 4 will be described. FIG. 7 is a flowchart showing the flow of processing in the flow line management device 4 according to the first embodiment. This flowchart is executed every predetermined time.

Subsequently, the flow line management unit 434 generates a flow line by generating the flow line information of the person based on the moving image information acquired in S1 (S4).

  Subsequently, the removal unit 435 performs a removal process for removing position information generated when the person is hardly moving from the flow line information indicating the generated flow line (S5). Since the removal process has been described with reference to FIG. 5, a detailed description thereof will be omitted.

Subsequently, the calculation unit 436 calculates the movement distance of the person indicated by the flow line (S6).
Subsequently, the person specifying unit 437 executes a target person specifying process for specifying a target person corresponding to each of the specified plurality of flow lines.

FIG. 8 is a flowchart showing a process flow corresponding to the target person specifying process executed by the person specifying unit 437 according to the first embodiment.
First, the person identifying unit 437 selects an unselected flow line (S71).

  Subsequently, the person specifying unit 437 determines whether or not the moving distance corresponding to the selected flow line is equal to or greater than the first distance (S72). If the person identification unit 437 determines that the movement distance is equal to or greater than the first distance, the process proceeds to S74. If the person identification unit 437 determines that the movement distance is less than the first distance, the process proceeds to S73.

  In S73, the person specifying unit 437 specifies the position where the person stays for a predetermined time or more based on the flow line, and the target person based on the reception history information corresponding to the transmitter 2 installed at the position. Is identified. When the process of S73 ends, the person identification unit 437 moves the process to S77.

  In S74, the person specifying unit 437 determines whether or not the moving distance corresponding to the selected flow line is equal to or longer than the second distance longer than the first distance. If the person identification unit 437 determines that the movement distance is equal to or greater than the second distance, the process proceeds to S76. If the person identification unit 437 determines that the movement distance is less than the second distance, the process proceeds to S75.

  In S75, the person specifying unit 437 specifies the target person based on the moving speed of the person indicated by the flow line, the moving speed of each of the plurality of terminals 3, and the reception history information. When the process of S75 ends, the person identification unit 437 moves the process to S77.

In S <b> 76, the person specifying unit 437 specifies the target person based on the moving speed of the person indicated by the flow line and the moving speeds of the plurality of terminals 3.
Subsequently, the person specifying unit 437 determines whether there is an unselected flow line (S77). If it is determined that there is an unselected flow line, the person specifying unit 437 moves the process to S71, and if it is determined that there is no unselected flow line, the process related to this flowchart ends.

By doing in this way, the flow line management apparatus 4 can specify the person corresponding to the flow line with high accuracy even when the person corresponding to the flow line hardly moves.

Second Embodiment
[The removal unit 435 adjusts a predetermined distance used for erasing position information]
Next, the second embodiment will be described. A person included in an image photographed by the photographing apparatus 1 appears larger as the person is closer to the photographing apparatus 1. For this reason, the noise included in the flow line of the person specified by the imaging apparatus 1 by the flow line management unit 434 decreases as the person is closer to the imaging apparatus 1. Further, the closer the person is to the transmitter 2, the more accurate the terminal 3 can receive the beacon ID. For this reason, the identification accuracy of the flow line based on the reception history information by the flow line management unit 434 becomes higher as the person corresponding to the flow line is closer to the transmitter 2.

  Therefore, in the flow line management system S according to the second embodiment, the removal unit 435 sets the predetermined distance used for the determination of the removal of the position information as the distance between the person corresponding to the flow line and the photographing apparatus 1, the person and the transmission. The movement distance calculated by the calculation unit 436 is indirectly adjusted based on the distance between the flow line and the imaging device 1 and the distance between the flow line and the transmitter 2 by changing the distance based on the distance to the machine 2. Thus, it is different from the first embodiment. The flow line management system S according to the second embodiment will be described below. In addition, description is abbreviate | omitted suitably about the same part as 1st Embodiment.

  In the second embodiment, the removing unit 435 shortens the predetermined distance when the person indicated by the flow line is present in a predetermined ratio or more in the area within the first range from the position of the photographing apparatus 1, and reduces the predetermined distance within the first range. When there is no predetermined ratio or more in the area, the predetermined distance is increased. Specifically, the removal unit 435 calculates the ratio of the plurality of positions indicated by the plurality of position information included in the flow line information corresponding to the flow line, from the position of the imaging device 1 to the area within the first range. Identify. The removing unit 435 relatively shortens the predetermined distance used for determining the removal of the position information when the specified ratio is equal to or greater than the predetermined ratio, and the position information when the specified ratio is less than the predetermined ratio. The predetermined distance used for the determination of removal is relatively increased.

  Thereby, when the flow line exists in an area within the first range from the position of the photographing apparatus 1, the position information is difficult to be removed. Therefore, when the flow line exists in an area within the first range from the position of the imaging device 1, the movement distance calculated by the calculation unit 436 with respect to the flow line increases, and the speed information is increased. The opportunity to identify the target person based on the number increases.

  In addition, the removal unit 435 increases the predetermined distance when the person indicated by the flow line exists in an area within the second range from the position of the transmitter 2 and increases the predetermined ratio to the area within the second range. When there is no more, the predetermined distance is shortened. Specifically, the removal unit 435 exists in an area within the second range from the position of the nearest transmitter 2 among the plurality of positions indicated by the plurality of position information included in the flow line information corresponding to the flow line. Specify the percentage. The removal unit 435 relatively increases the predetermined distance used for determination of the removal of the position information when the specified ratio is equal to or greater than the predetermined ratio, and the position information when the specified ratio is less than the predetermined ratio. The predetermined distance used for the determination of removal is relatively shortened.

  Thereby, when the flow line exists in an area within the second range from the position of the transmitter 2, the position information is easily removed. Therefore, when the flow line exists in an area within the second range from the position of the transmitter 2, the movement distance calculated by the calculation unit 436 with respect to the flow line increases, and the reception history is increased. Opportunities to identify the target person based on the information increase.

[Effects of Second Embodiment]
As described above, the flow line management device 4 according to the second embodiment sets the predetermined distance when the person indicated by the flow line is present in the area within the first range from the position of the imaging device 1 at a predetermined ratio or more. The distance is shortened, and the predetermined distance is increased when the area within the first range does not exist in a predetermined ratio or more. By doing in this way, when the position of the flow line is close to the position of the imaging device 1, the flow line management device 4 can increase the chances of specifying the target person based on the speed information. When the position of the flow line is close to the position of the image capturing apparatus 1, noise included in the flow line is reduced, so that the matching accuracy between the moving speed based on the flow line and the moving speed of the target person indicated by the speed information is improved. Therefore, the flow line management device 4 can improve the identification accuracy of the target person corresponding to the flow line.

  Further, the flow line management device 4 increases the predetermined distance when the person indicated by the flow line is present in a predetermined ratio or more in the area within the second range from the position of the transmitter 2, and sets the area within the second range. When there is no predetermined ratio or more, the predetermined distance is shortened. By doing in this way, the flow line management apparatus 4 can increase the opportunity to identify the target person based on the reception history information when the position of the flow line is close to the position of the transmitter 2. When the position of the flow line is close to the position of the transmitter 2, the accuracy of specifying the target person based on the reception history information is improved, so the flow line management device 4 improves the specification accuracy of the target person corresponding to the flow line. Can do.
