BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, in all the drawings, the same constituent elements are denoted by the same reference numerals, and the description thereof will be omitted as appropriate.

FIG. 1 is a diagram for explaining the usage environment of an information generating device 10 according to an embodiment. The information generation device 10 is used to notify users of the station of the congestion status of the platform H of the station. Specifically, at least one imaging unit 20 is installed in the home H. As shown in FIG. The information generating device 10 processes the image generated by the imaging unit 20 to generate data indicating the congestion status of the home H (hereinafter referred to as congestion data).

In this embodiment, the home H is connected to a plurality of routes S. Route S is, for example, one of stairs, elevators, and escalators. The information generation device 10 manages the home H by dividing it into a plurality of areas A for each route S. FIG. In other words, in the information generating device 10, the plurality of areas A are linked to different routes S from each other. The congestion data indicates the degree of congestion for each of these plurality of areas A. FIG. Then, the information generation device 10 uses the congestion data to generate information (hereinafter referred to as recommended information) indicating which route S should be taken when going to the home H. FIG.

In the example shown in FIG. 1, the imaging unit 20 is provided for each of the plurality of regions A. In the example shown in FIG. However, a plurality of imaging units 20 may be provided for one region A, and one imaging unit 20 may correspond to a plurality of regions A.

The information generation device 10 outputs the generated recommended information to the display device 30 . The display device 30 displays recommended information acquired from the information generating device 10 . The display device 30 is, for example, a terminal held by a station user, but may be a display installed in the station premises or at the ticket gate, or may be a display installed outside the station. good. A user of the station or a person who intends to use the station can recognize the route to be taken when going to the platform H by viewing the recommended information displayed on the display device 30 .

The information generating device 10 can also use information stored in the server 40 when generating recommended information.

As an example, the server 40 stores schedule information of events held near the station for each station. For example, when it is assumed that a participant of a certain event uses a certain station, the server 40 stores the schedule information of the event in association with the station. Here, the schedule information stores at least information for estimating the date and time of the event, the date and time of the end of the event, and the number of participants in the event. The information for estimating the participants of the event includes at least one of the venue and capacity of the event, and/or the number of participants of the event provided by the organizer of the event. The schedule information may also include the location of the event.

Examples of the server 40 include a server managed by a railway company and a server managed by a local government. It is not limited to these. In addition, if the event is an election speech held in a station square or the like, a live performance on the street, or the like, the server 40 may generate event information using information on the Internet. The information on the Internet used here may be, for example, information posted on an SNS (social networking service) or news posted on an information providing site.

As another example, the server 40 stores weather information for each region. The weather information may be data indicating the current weather, data predicting future weather, or both. Then, the information generation device 10 acquires the weather information of the region to which the target station belongs from the server 40 .

The information generating device 10 then uses the information acquired from the server 40 to predict the congestion situation.

FIG. 2 is a diagram showing an example of the functional configuration of the information generation device 10. As shown in FIG. In the example shown in this figure, the information generation device 10 has an image processing section 110 and an information generation section 120 .

The image processing unit 110 acquires an image from the imaging unit 20 together with information identifying the imaging unit 20 (hereinafter referred to as imaging unit identification information). The image processing unit 110 then processes the image acquired from the imaging unit 20 to generate the congestion data described above.

As described above, the congestion data includes the degree of congestion for each area A. The image processing unit 110 generates, as the degree of congestion, the area ratio of the areas in the image where people can be located but where there are no people. Here, the area in which a person can be positioned is, for example, an area in the area A inside the white line and in which no object such as a pillar or a vending machine is placed. Further, the image processing unit 110 may calculate the number of people present in the area A and divide this number by the capacity set for each area A to generate the degree of congestion.

The image processing unit 110 uses information stored in the area information storage unit 112 when generating congestion data. The area information storage unit 112 stores information necessary for generating congestion data for each area A. FIG. The information stored in the area information storage unit 112 is, for example, the imaging unit identification information of the imaging unit 20 corresponding to the area A, the above capacity, and the like. Then, the image processing unit 110 uses the information stored in the area information storage unit 112 so that for each area A, the imaging unit 20 corresponding to the area A, the image generated by the imaging unit 20, and the area A identify the capacity of

In the example shown in this figure, the area information storage unit 112 is a part of the information generation device 10, but may be located outside the information generation device 10. FIG.

The information generation unit 120 generates the recommended information described above using the congestion data. For example, the area information storage unit 112 stores, for each area A, information specifying the route S corresponding to the area A. FIG. In other words, in the area information storage unit 112, multiple areas A are associated with different routes S from each other. Then, the information generation unit 120 uses the area information storage unit 112 to generate information that can identify the route S linked to the area A with the lowest congestion degree. This information is an example of recommended information.

The information generator 120 may use information stored in the server 40 when generating the congestion data.

For example, the information generation unit 120 reads the schedule information of the event linked to the station having the platform H in the server 40, and generates the recommendation information using this schedule information. As an example, the information generation unit 120 estimates the degree of congestion from the present time forward using the date and time of the event, the date and time of the end of the event, and the number of participants in the event. This estimation may be performed using, for example, the result of statistically processing the past performance, or the result of machine learning of the past performance. The past record used here includes, for example, the date and time of the event, the date and time of the end of the event, the number of participants in the event, and the degree of congestion for each time on the day of the event. An example of the training data for machine learning is the date and time of the event, the date and time of the end of the event, and the number of participants in the event, labeled with the degree of congestion for each time on the day of the event. Then, the information generation unit 120 identifies the route S to be used for each time using the estimated value of the degree of congestion for each time. The method of specifying the route S to be used is as described above.

In addition, when the schedule information includes the venue of the event, the information generation unit 120 may estimate the crowded entrances and ticket gates in the station and cause the display device 30 to display the estimation result. . This estimation may be performed, for example, by machine learning, or may be performed using the positional relationship between the venue of the event and the ticket gate of the station.

In addition, the information generator 120 may read the weather information of the area corresponding to the station having the platform H in the server 40 and generate the recommended information using this weather information. For example, the information generator 120 reads necessary weather information from the server 40, and uses this weather information to estimate the degree of congestion from the present time forward. This estimation may be performed using, for example, the result of statistically processing the past performance, or the result of machine learning of the past performance. Past records used here include, for example, weather conditions (including at least weather) and hourly congestion levels. An example of training data for machine learning is the day's weather information labeled with the degree of congestion for each hour. Then, the information generation unit 120 identifies the route S to be used for each time using the estimated value of the degree of congestion for each time. The method of specifying the route S to be used is as described above.

FIG. 3 shows a first example of recommended information. In the example shown in this figure, the recommendation information includes information specifying the route S to be used.

FIG. 4 shows a second example of recommended information. In the example shown in this figure, the recommended information indicates the degree of congestion of the area A associated with each route S for each of multiple routes S. FIG. The user then recognizes the route S with the lowest degree of congestion as the route S to be used.

In the examples shown in FIGS. 3 and 4, the congestion data includes data indicating the position of the route S to be used (for example, map data of station premises including information indicating the route S to be used). good too. In this case, the congestion data is a diagram showing the platform H, and may include a diagram that is color-coded (or pattern-coded) according to the degree of congestion.

As described above, one example of the installation position of the display device 30 is near an escalator or a staircase in the premises of a station. Here, when the degree of congestion in area A corresponding to a certain escalator or staircase is equal to or greater than a reference value, the information generation unit 120 displays the information on the display device 30 installed on that escalator or staircase to indicate the people who have used the escalator or route S. , a display for guiding the user to an area A that does not correspond to the escalator or the route S may be displayed. An example of this display is "the vicinity of the pillar D, which is 15 meters ahead after getting off the escalator, is vacant".

Another example of the display device 30 is a terminal held by a station user. In this case, the information generator 120 may transmit the congestion degree for each area A to the display device 30 . Based on the position information of the display device 30, the display device 30 can then determine whether the current position is in a crowded place. If the place is crowded, the display device 30 performs processing, such as displaying and/or vibrating, to prompt the user to move to another place.

Each function corresponding to the program module is realized by the processor 1020 reading each program module into the memory 1030 and executing it. The storage device 1040 also functions as the area information storage unit 112 .

The input/output interface 1050 is an interface for connecting the information generating apparatus 10 and various input/output devices. For example, the information generation device 10 communicates with the imaging unit 20 and the display device 30 inside the station via the input/output interface 1050 .

Network interface 1060 is an interface for connecting information generating apparatus 10 to a network. This network is, for example, a LAN (Local Area Network) or a WAN (Wide Area Network). A method for connecting the network interface 1060 to the network may be a wireless connection or a wired connection. The information generating device 10 may communicate with the imaging section 20 and the display device 30 via the network interface 1060 .
