Embodiments for Carrying Out the Invention

[0012] Hereinafter, with reference to the drawings, the configuration of a departure and arrival time display system 10 according to an embodiment of the present invention will be described. The departure and arrival time display system 10 according to this embodiment displays, on the display 5 which is the screen of the mobile terminal 1, the departure and arrival times of buses at the bus stop pole (also called a pole) imaged by the mobile terminal 1, as shown in FIGS. 5 and 8. Thereby, when the user arrives at the bus stop where they intend to board a bus, as shown in FIG. 11, by photographing the bus stop pole with the camera 4 of the mobile terminal 1, as shown in FIGS. 5 and 8, the departure and arrival times of the bus can be confirmed on the display 5 of the mobile terminal 1. Therefore, the user can confirm the departure and arrival times of the bus without looking at the timetable posted on the pole.

[0013] As shown in FIG. 1, the departure and arrival time display system 10 includes, for example, a mobile terminal 1 and an information processing device 2, etc., and the mobile terminal 1 and the information processing device 2 are connected via a network.

[0014] The mobile terminal 1 is a smartphone, a tablet terminal, a personal computer, etc. For the display of departure and arrival times, an application may be executed via a web browser, or an application may be installed and executed on the mobile terminal 1. The mobile terminal 1 includes a control unit 3 by a CPU etc., a camera 4, a display 5, an operation unit 6, a transmission / reception unit 7, a storage unit 8 by a ROM, a RAM, etc. Various functions of the mobile terminal 1 are realized by a program. The transmission / reception unit 7 transmits the image data imaged by the camera 4 to the information processing device 2. Also, the transmission / reception unit 7 receives the departure and arrival time information determined by the information processing device 2, or receives information regarding candidate poles or candidate buses extracted by the information processing device 2, etc.

[0015] The information processing device 2 may be a server device composed of a single or multiple computers, or may be a cloud system. The information processing device 2 includes a control unit 9 by a CPU etc., a transmission / reception unit 11, a storage unit 12 by a ROM, a RAM, etc. Various functions of the information processing device 2 are realized by a program. The transmission / reception unit 11 receives image data from the mobile terminal 1, or transmits departure and arrival time information etc. to the mobile terminal 1.

[0016] As shown in FIG. 2, the control unit 9 includes a character recognition unit 13, a signpost identification unit 14, a first time information acquisition unit 15, a second time information acquisition unit 16, a destination information acquisition unit 17, and the like.

[0017] The character recognition unit 13 recognizes characters included in an image obtained by imaging a signpost of a bus stop transmitted from the mobile terminal 1 by OCR (Optical Character Recognition) processing, and acquires character information based on the recognized characters.

[0018] The signpost identification unit 14 collates the character information acquired by the character recognition unit 13 with the operator information, stop / signpost information, schedule information, departure / arrival time information, etc. recorded in the storage unit 12, and identifies one or more signposts.

[0019] Based on the one or more signposts identified by the signpost identification unit 14, the departure / arrival time information recorded in the storage unit 12, and the current time, the first time information acquisition unit 15 acquires one or more pieces of departure / arrival time information at the identified signposts.

[0020] Based on the signposts identified by the signpost identification unit 14 and the departure / arrival time information recorded in the storage unit 12, the second time information acquisition unit 16 acquires departure / arrival time information having a passing order later than that of the signposts identified by the signpost identification unit 14.

[0021] The destination information acquisition unit 17 acquires, as the destination of the bus departing / arriving at the signposts identified by the signpost identification unit 14, the information on the signposts included in the departure / arrival time information acquired by the second time information acquisition unit 16.

[0022] The transmission / reception unit 11 transmits the departure / arrival time information acquired by the first time information acquisition unit 15 to the mobile terminal 1. The transmission / reception unit 11 transmits the destination of the bus obtained by the destination information acquisition unit 17 in association with the plurality of departure / arrival time information acquired by the first time information acquisition unit 15. Thereby, on the mobile terminal 1, the departure times of a plurality of buses can be displayed separately for each destination, or the destinations can be displayed so as to be selectable by the user, and when the destination is selected by the user, the departure time of the bus related to the selected destination can be displayed.

[0023] The storage unit 12 stores a departure / arrival time database related to the departure / arrival times of transportation means and position information (geographical information) such as stops. The departure / arrival time database is stored in a format such as GTFS (General Transit Feed Specification), for example.

[0024] As shown in FIG. 3, for example, the departure / arrival time database has operator information, stop / landmark information, route information, bus information, departure / arrival time information, operation section information, operation date information, and the like.

[0025] The operator information is information related to a transportation means, for example, a bus company that operates the operation of a route bus. The operator information includes an operator ID (identification number, identification symbol, etc.) for identifying the operator, an operator name, and the like.

[0026] The stop / landmark information (departure / arrival place information) is information related to a stop (bus stop) that is a departure / arrival place of a transportation means, for example, a route bus, and a landmark. The landmark means a pole of a stop. When there are a plurality of landmarks with the same stop name, the stop / landmark information is set as another landmark. For example, when there are landmarks for going up and down with the same stop name, or when there are a plurality of landmarks at a terminal or the like, the stop / landmark information is set for each of the plurality of landmarks. The stop / landmark information includes a stop / landmark ID for identifying the stop / landmark, a stop / landmark name, the latitude and longitude of the stop or landmark, and the like.

[0027] The stop and post information may include the stop and post classification (whether it is a stop or a post), the parent stop information (the parent-child relationship between stops and posts), and the platform information (information such as platform symbols and numbers within the terminal). As a result, as the setting patterns for posts and stops, only three patterns are available: representative points only, posts only, and parent-child settings.

[0028] Route information is information regarding the operating routes of transportation means, such as route buses. Route information is set for each route that users of transportation means, such as route buses, recognize as one operating unit. When the fare, system number, route name, route color, route character color, etc. are different, they are set as separate routes. Route information includes a route ID for specifying the route, an operator ID (referenced from operator information), a route abbreviation (such as a system number or route name), a route name (information regarding a route including destinations and via points, etc.). The route ID is associated with the trip IDs of multiple buses operating on the same route. As a result, multiple trips operating on the same route are managed collectively. Either the route abbreviation or the route name may be used.

[0029] Trip information is information regarding trips operating along the operating routes of transportation means, such as route buses. Trip information is set for each trip, where one continuous ride that passengers can take is considered one trip. Trip information includes a trip ID for specifying the trip, a route ID (referenced from route information), and an operating day ID (referenced from operating classification information or operating day information). Trip information may also include the trip destination (such as the destination and via points of each trip).

[0030] The arrival / departure time information is information regarding the passing time (arrival / departure time) of each stop for each bus. The arrival / departure time information is set for each bus at each stop's passing time. The arrival / departure time information includes a bus ID (referenced from bus information), arrival time, departure time, stop / kilometer post ID (referenced from stop / kilometer post information), passing order (the order of stops / kilometer posts through which the bus specified by the bus ID passes), and so on. Since the bus ID is included in the arrival / departure time information, all stops / kilometer posts through which each operating bus passes are associated based on the bus ID. Also, based on the passing order included in the arrival / departure time information, the next bus stop, destination, via points, and other destinations of each bus at the specified stop / kilometer post can be identified.

[0031] The operation classification information is information regarding operation classifications such as weekdays and holidays. The operation classification information includes an operation day ID (a value representing the operation classification), operation / non-operation on each day of the week, and so on.

[0032] The operation day information is information regarding exceptional operation days such as holidays that are not based on the operation classification. The operation day information includes an operation day ID, date, application / non-application of the operation classification, and so on. The operation day information is not limited to the definition of exceptional operation days, and all days may be defined by the operation day information instead of the above-described operation classification information.

[0033] Next, with reference to FIG. 4, the operation of the arrival / departure time display system 10 according to the present embodiment will be described. First, the bus user uses the camera 4 of the mobile terminal 1 to image the kilometer post of the bus stop where they intend to board (step S11). In the arrival / departure time display system 10, the image captured by the user is used for the purpose of identifying the bus stop based on the characters recognized by the OCR process and displaying the arrival / departure time of the identified bus stop on the mobile terminal 1.

[0034] For the above object, it is desirable that the image of the signpost to be imaged includes the name of the bus stop. However, when the name of the bus stop is not indicated on the signpost at a terminal or the like, an image including the route symbol or route number indicated on the signpost may also be used. In addition, the image of the signpost may include the name of the bus company, the name of the destination (hereinafter, the general term for the destination and the via point is referred to as the destination), and the name of the next bus stop.

[0035] The mobile terminal 1 transmits the image captured by the camera 4 to the information processing device 2 using an application via a web browser or an application installed in the mobile terminal 1 (step S12).

[0036] The information processing device 2 receives the above image from the mobile terminal 1 (step S21), and the character recognition unit 13 performs OCR processing (step S22). By the OCR processing, the characters included in the image are recognized and character information is obtained. The character information obtained by the OCR processing is, for example, the name of the bus stop, the name of the bus company, the name of the destination, the name of the next bus stop, or the route symbol or route number.

[0037] Next, in the information processing device 2, the signpost identification unit 14 collates the character information obtained by the OCR processing with the operator information, the stop / signpost information, the route information, the schedule information, the departure / arrival time information, the operation section information, the operation date information, etc. recorded in the storage unit 12 of the information processing device 2 (step S23).

[0038] For example, when the name of the bus company and the name of the bus stop are indicated on the signpost, the signpost identification unit 14 collates the characters recognized by the OCR processing in the image of the signpost with the operator information and the stop / signpost information, thereby identifying the name of the operator such as the bus company and the name of the bus stop (step S24).

[0039] When the name of the operator is specified, the operator ID is obtained, and thus the route information, flight information, departure / arrival time information, stop / pillar information, etc. associated with the operator ID are referred to. As a result, when the departure / arrival time display system 10 includes the departure / arrival time databases of a plurality of operators, extraction processing within a limited range becomes possible. For example, when the same bus stop name exists in different bus companies, it becomes easy to distinguish between the two.

[0040] When the bus stop name is specified, the stop / pillar ID is obtained based on the stop / pillar information (step S25). When only one pillar is provided at one stop, only one stop / pillar ID is obtained by the collation process by the pillar identification unit 14. When two or more pillars are provided at one stop, a plurality of stop / pillar IDs are obtained by the collation process by the pillar identification unit 14. The case where two or more pillars are installed at one stop includes, for example, the case where one pillar is installed on each side of the road, the case where there are bus stops with the same name in different locations, the case where a plurality of pillars are installed at the bus terminal, and the like.

[0041] Based on the one or more obtained stop / pillar IDs, the departure / arrival time information recorded in the storage unit 12, and the current time, the first time information acquisition unit 15 acquires the departure / arrival time information including the stop / pillar ID (step S26). As a result, the departure / arrival time information regarding the flights departing / arriving at the specified stop / pillar is obtained. In the first time information acquisition unit 15, by acquiring the departure / arrival time information after the current time, the arrival times and departure times of a plurality of flights arriving after the current time are obtained. When dynamic data can be acquired, it is also possible to acquire the departure / arrival time information of flights that are scheduled to arrive before the current time but have not yet arrived. When a plurality of stop / pillar IDs are obtained, the departure / arrival time information is obtained for all of the obtained stop / pillar IDs, and the arrival times and departure times of the obtained plurality of flights are obtained.

[0042] The arrival / departure time information obtained by the transceiver unit 11 is transmitted to the mobile terminal 1 (step S27), and the mobile terminal 1 receives the arrival / departure time information (step S13). As a result, on the mobile terminal 1, it is possible to display the arrival time and / or departure time of the flight(s) whose arrival is scheduled. The mobile terminal 1 uses an application via a web browser or an application installed in the mobile terminal 1 to display, on the display 5, the arrival / departure time of the flight(s) scheduled to arrive at the bus stop as shown in FIG. 5 based on the received flight information and the arrival / departure time information (step S14). Note that the arrival / departure time displayed on the display 5 may be only the arrival / departure time of the flight immediately after the current time, or the arrival / departure times of multiple flights. Also, the display of the arrival / departure time may be in a list format as shown in FIG. 5, or in a display format using AR (augmented reality) technology that overlays and displays with the image captured by the camera 4.

[0043] Note that the flight information recorded in the storage unit 12 includes a route ID. By using the route ID included in the flight information, route information can be referenced, and a route abbreviation (system number, route name, etc.) and a route name (information about a route including a destination, a via point, etc.) can be obtained. On the mobile terminal 1, by displaying the departure times of multiple flights as well as the route abbreviation and the route name on the display 5, the user can confirm the departure time of the flight(s) scheduled to board together with the route abbreviation and the route name.

[0044] As a result, a user of a bus whose pole has been imaged by the mobile terminal 1 can obtain the time of the flight(s) scheduled to arrive at the bus stop.

[0045] Hereinafter, with reference to FIG. 6, a method for obtaining the destination information of each flight will be described. As shown in FIG. 3, the arrival / departure time information recorded in the memory unit 12 includes the flight ID, arrival time, departure time, stop / pillar ID, and passing order. When a plurality of arrival / departure time information is referenced by the same flight ID, as shown in FIG. 7, all the stops / pillars passed by that flight are grasped together with the passing order, and the departure place, destination, and route of that flight can be known. Therefore, by referring to all the arrival / departure time information with the same flight ID, the destination of each flight is obtained.

[0046] As described above, in step S25, the bus stop name is specified by the pillar specifying unit 14, and the stop / pillar ID of the pillar is obtained. Next, the arrival / departure time information including the obtained stop / pillar ID is referenced (step S31), and the flight ID is obtained from the arrival / departure time information (step S32). By obtaining the flight ID, other arrival / departure time information having the same flight ID is extracted (step S33). Since the passing order is included in the extracted arrival / departure time information, the passing order is obtained from each arrival / departure time information (step S34). As a result, since a plurality of arrival / departure time information is referenced by the same flight ID, as shown in FIG. 7, all the stops / pillars passed by that flight are grasped together with the passing order.

[0047] Then, for a plurality of stops, the departure place, destination, and route are determined based on the passing order. Thereby, the stop / pillar corresponding to the destination (departure place, destination, and route) of that flight is obtained (step S35).

[0048] Note that the flight information recorded in the memory unit 12 may include the flight destination. In this case, regardless of the method for obtaining the destination information of each flight described above, the name of the stop corresponding to the destination (departure place, destination, and route) of the flight can be obtained. However, the flight destination included in the flight information may be limited to only the destination, or there may be a possibility that the destination and the route cannot be distinguished. Therefore, according to the method for obtaining the destination information of each flight, it is possible to refer to all the stops of each flight together with the passing order, so that the destination of each flight can be surely obtained.

[0049] In step S27, when the plurality of arrival / departure time information acquired by the first time information acquisition unit 15 is transmitted to the mobile terminal 1, information regarding the destination of each flight is also transmitted. As a result, on the mobile terminal 1, the departure times of the plurality of flights can be displayed separately for each destination. Thereby, as shown in FIG. 8, the user can confirm the departure time of the flight for which they have a boarding reservation for each destination.

[0050] Alternatively, before displaying the departure time on the mobile terminal 1, based on the information regarding the destination of each flight acquired, as shown in FIG. 9, the destination that the user wishes to display may be selectively displayed on the display 5 of the mobile terminal 1. When the destination is selected by the user, the mobile terminal 1 displays the departure time of the flight related to the selected destination.

[0051] Hereinafter, with reference to FIG. 10, a case where character information other than the bus stop name is acquired in the characters recognized by the OCR process will be described. When character information of the bus stop name imaged by the user is acquired based on the characters recognized by the OCR process and a plurality of stop / stake IDs are acquired, as described above, arrival / departure time information is acquired for all of the acquired stop / stake IDs, and the arrival times and departure times of the plurality of flights acquired are obtained. On the other hand, if there is character information other than the bus stop name, the number of arrival / departure time information transmitted to the mobile terminal 1 is limited in advance, making it easier for the user to refer to the departure time displayed on the mobile terminal 1.

[0052] Specifically, as shown in FIG. 11, if the captured image includes character information such as the next bus stop name or destination, the necessary arrival / departure time information can be limited. For example, when characters such as "next", "direction", "via", "going" are recognized by the OCR process, in the post identification unit 14, a determination process is performed to determine that the characters adjacent to these characters are the name of the next bus stop or destination. Also, when characters such as "here is" are recognized by the OCR process, in the post identification unit 14, a determination process is performed to determine that the characters adjacent to these characters are the name of the bus stop at the boarding location that was imaged (step S41).

[0053] When characters determined to be the name of the next bus stop or destination are extracted, the stop - post ID corresponding to the name of the next bus stop or destination is acquired based on the stop - post information recorded in the storage unit 12 (step S42).

[0054] As described above, in the destination information acquisition unit 17, based on the stop - post ID of the boarding location and the stop - post information recorded in the storage unit 12, destinations such as the via points and destinations of each bus are separately acquired. Therefore, the stop - post ID corresponding to the separately acquired destination is collated with the stop - post ID corresponding to the name of the next bus stop or destination included in the captured image (step S43).

[0055] As a result of the collation, if there is a stop - post ID corresponding to the name of the next bus stop or destination that matches, only the departure and arrival time information regarding the bus including the matching stop - post ID is acquired (step S44). Then, the acquired departure and arrival time information is transmitted to the mobile terminal 1 (step S45).

[0056] When the character information of the imaged bus stop name is acquired, even if a plurality of stop - post IDs are acquired, since the name of the next bus stop or destination can be obtained from the image, it is possible to limit the departure and arrival time information transmitted to the mobile terminal 1. For example, when posts are installed one by one on both sides of the road, when there are bus stops with the same name in different locations, or when there are multiple posts installed at a bus terminal, a plurality of stop - post IDs are acquired. At this time, if the stop - post ID corresponding to the name of the next bus stop or destination can be acquired, the specific post among the imaged posts can be identified. Thereby, the bus stop for which the departure and arrival time is to be displayed can be accurately specified. As a result, the trouble for the user to specify the destination and route of the bus to board is reduced.

[0057] In addition, the route information recorded in the storage unit 12 may include a line number and a route name. Therefore, if the captured image contains the character names of the line number and the route name as shown in FIG. 11, the flight information can be limited based on the route ID included in the route information. As a result, even when a plurality of departure / arrival time information is acquired in the first time information acquisition unit 15, it is possible to limit the departure / arrival time information transmitted to the mobile terminal 1 by limiting it to only the departure / arrival time information including the flights related to the route information.

[0058] Furthermore, the bus stop and pillar information recorded in the storage unit 12 may include platform information such as platform symbols and platform numbers. Therefore, if the captured image contains the character information of the platform symbol and the platform number, in the pillar identification unit 14, not only the bus stop name but also the bus stop and pillar ID can be acquired based on the platform information. As a result, since the number of bus stop and pillar IDs acquired based on the image is limited, it is possible to limit the departure / arrival time information transmitted to the mobile terminal 1. Depending on the bus company, since the number of bus terminals is limited, the bus stop and pillar information including platform information such as platform symbols and platform numbers may also be limited. In this case, if the platform symbol and the platform number are included in the image, even when the bus stop name of the boarding place is not captured, it may be possible to identify the pillar of the boarding place while using other character information.

[0059] As described above, according to the present embodiment, by capturing the pillar of the bus stop, the pillar is identified and the time of the flight scheduled to arrive at the mobile terminal 1 can be displayed. If the pillar cannot be uniquely identified, the departure times of a plurality of flights are separated and displayed for each destination, or the destinations are displayed so that they can be selected by the user, and when the destination is selected by the user, the departure time of the flight related to the selected destination is displayed.

[0060] Further, according to the present embodiment described above, even when arrival and departure time information is not recorded in the memory unit 12 in the form of a "pillar timetable" for each bus stop pillar, the arrival and departure times of the buses scheduled to arrive at the identified pillar can be displayed. That is, in the arrival and departure time database according to the present embodiment such as GTFS data, arrival and departure time information regarding the arrival and departure times of stops for each bus is recorded in association with bus information and stop / pillar information.

[0061] On the other hand, in order to create and record a pillar timetable, it is necessary to extract the buses scheduled to arrive and depart at each bus stop, and it takes time and effort to create and record the pillar timetable. In contrast, the arrival and departure time database according to the present embodiment can be constructed if there is route information regarding the operation route of a transportation means, for example, a route bus, bus information regarding the buses operating along the operation route, and arrival and departure time information regarding the arrival and departure times of stops for each bus, and it is constructed without creating a pillar timetable. Therefore, the arrival and departure time display system 10 according to the present embodiment can be implemented even by operators who do not construct a pillar timetable for each bus stop.

[0062] Next, a case where an advertisement display function is added to the arrival and departure time display system 10 according to the present embodiment will be described. In the above embodiment, advertisement information to be displayed on the mobile terminal 1 is recorded in the memory unit 12 of the information processing device 2. The advertisement information is advertisement content associated with the above-described route information, bus information, stop / pillar information, and arrival and departure time information. The information processing device 2 includes an advertisement extraction unit 21 that extracts the advertisement information recorded in the memory unit 12 (see FIG. 2). Note that the present invention includes cases where an advertisement display function is not provided.

[0063] In step S24, the pillar of the bus stop used by the user is identified from the captured image, and in step S26, arrival and departure time information regarding the buses scheduled to arrive is acquired. Therefore, the advertisement extraction unit 21 extracts advertisement information associated with the pillar identified by the pillar identification unit 14, the buses included in the arrival and departure time information acquired by the first time information acquisition unit 15, the route information based on the buses, and the like.

[0064] Then, the information processing device 2 transmits information regarding the extracted advertisement content to the mobile terminal 1, and the mobile terminal 1 displays the advertisement on the screen. As a result, advertisements related to bus stops, buses, and routes used by the user are displayed on the mobile terminal 1.

[0065] Thereby, when the arrival and departure times of the bus are displayed on the mobile terminal 1, advertisements with a high degree of relevance to the user and the surrounding area can be displayed on the mobile terminal 1. When the advertisement information is associated with the bus stop - pillar information, advertisements with a high degree of relevance to a specific location near the pillar can be displayed. When the advertisement information is associated with the route information or bus information, advertisements with a high degree of relevance along the route of the transportation means can be displayed. In addition, when there is advertisement information associated with an operator, when the operator such as a bus company is identified in step S24, the advertisement information associated with the operator may be extracted and transmitted to the mobile terminal 1.

[0066] In the above - described embodiment, the case where the transportation means is a bus and the arrival and departure times of the bus are displayed by imaging the pillars of the bus stop has been described, but the present invention is not limited to this example.
