[Technical field]

[0001] The present invention relates to an information processing device that records acquired information and performs data processing to provide the information, although the use of the present invention is not limited to information processing devices. [Background technology]

[0002] Conventionally, a technique has been disclosed that provides identifiable information about facilities that are frequently designated as destinations for mobile objects, allowing users to easily grasp popular facilities (see, for example, Patent Document 1 below). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2008-14669 A Summary of the Invention [Problem to be solved by the invention]

[0004] In the above conventional technology, since a facility is searched for simply based on the number of times it has been set as a destination, the destination to be set varies greatly depending on the point from which the user departs and the direction from which the user is heading to the destination. This causes a problem in that it is not possible to know to which destination a mobile object traveling on a certain road is heading, and for example, it is not possible to know popular facilities when traveling in the same direction as the user's own vehicle. [Means for solving the problem]

[0005] In order to solve the above-mentioned problems and achieve the object, the information processing device of the invention of claim 1 is characterized in that it comprises an acquisition unit that acquires at least information indicating a position of a departure point and information indicating a position of a destination from a terminal as route information when a route is searched by the terminal, a memory unit that stores the route information acquired by the acquisition unit, a generation unit that generates ranking information regarding the destination based on the route information stored in the memory unit, and a transmission unit that transmits the ranking information regarding the destination generated by the generation unit to the terminal.

[0007] (Embodiment) DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of an information processing apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

[0008] 1 is a block diagram showing an example of a functional configuration of an information recording system according to an embodiment. The information recording system according to the embodiment can be configured with an information recording device 100 and an information acquiring device 110 that are communicatively connected to each other.

[0009] The information recording device 100 includes an acquisition unit 101, an association unit 102, and an output unit 103. The information acquisition device 110 includes a designation unit 111, a transmission unit 112, and an acquisition unit 113.

[0010] The information recording device 100 can be configured using a single server, but is not limited to this. The information recording device 100 may be configured using a plurality of servers distributed according to the functions of the acquisition unit 101, association unit 102, and output unit 103.

[0011] The acquisition unit 101 of the information recording device 100 acquires movement history information, which is information on the movement history of a mobile object, and destination information on destinations visited by the mobile object. The movement history is, for example, information in which the position of the mobile object is recorded at every predetermined time, or information in which the roads traveled by the mobile object are recorded at every predetermined time.

[0012] When the movement history is information that records the position of the mobile object at every predetermined time, the acquisition unit 101 acquires date and time information when the mobile object moved its position together with the movement history, and acquires date and time information when the destination was set together with the destination information. When the movement history is information that records the roads on which the mobile object traveled at every predetermined time, the acquisition unit 101 acquires date and time information when the mobile object moved on the road together with the movement history.

[0013] The associating unit 102 associates the road on which the mobile object was traveling when the destination was set with the destination based on the movement history information and the destination information, and also associates the road with the destination based on date and time information when the mobile object moved on the road.

[0014] When the output unit 103 receives an acquisition request for road-related information or destination information from the information acquisition device 110, it outputs statistical information obtained by statistically processing the destination information associated with the road based on the association by the associating unit 102. This statistical information is output to the information acquisition device 110 that made the acquisition request.

[0015] The output unit 103 also has a function of matching the movement history with roads on the map information to specify the roads on which the moving object has traveled, and a function of outputting, as statistical information, a ranking of destination information by road direction and a ranking of roads by destination.

[0016] This information acquisition device 110 can be configured using, for example, an information processing device mounted on a moving body, a portable information processing device that can be moved, or an information processing device that is fixedly installed at home, a facility, etc. As these information processing devices, personal computers (PCs), notebook PCs, smartphones, tablet terminals, navigation devices, etc. can be used.

[0017] The designation unit 111 designates a road or a destination through a user's operation, etc. The transmission unit 112 transmits an acquisition request for the designated road or destination to the information recording device 100. The acquisition unit 113 acquires, from the information recording device 100, information on facilities visited by a user who traveled along a road, or information on roads traveled by a user who visited the destination.

[0018] At this time, the acquisition unit 101 of the information recording device 100 acquires the acquisition request transmitted from the transmission unit 112 of the information acquiring device 110, and outputs it to the output unit 103. Then, in response to the acquisition request, the output unit 103 outputs, to the acquisition unit 113 of the information acquiring device 110, information on facilities visited by the user who traveled along the road, or information on roads traveled by the user who visited the destination.

[0019] 2 is a flowchart showing an example of a processing procedure of the information recording system according to the embodiment. A description will be given of an information recording process executed by the information recording device 100. First, the information recording device 100 acquires movement history information of a moving object and destination information of destinations visited by the moving object (step S201).

[0020] Next, based on the movement history information and the destination information, the road on which the mobile object was traveling when the destination was set is associated with the destination (step S202). Then, when a request for acquiring information about the road or destination information is received from the information acquisition device 110, statistical information obtained by statistically processing the destination information associated with the road is output to the information acquisition device 110 (step S203).

[0021] According to the above process, the destination and the road used to travel to the destination are associated with the movement history of the moving object. This makes it possible to provide information about the road used to travel to the destination, or information about the destination of the moving object while traveling on the road. For example, the information acquisition device can obtain information about roads suitable for travel to the destination, and information about destinations (popular facilities) when traveling in the same direction as the vehicle itself. EXAMPLES

[0022] An embodiment of the present invention will be described below. In this embodiment, a configuration will be described in which a navigation device 300 is mounted on a moving body (vehicle), and each user's navigation device 300 accesses a server serving as the above-mentioned information recording device 100.

In addition, this navigation device 300 has a function as the above-mentioned information acquisition device 110, and can issue an acquisition request for road and destination information to the information recording device 100 (server).

[0023] (Hardware configuration of the navigation device 300) Next, the hardware configuration of the navigation device 300 will be described. Fig. 3 is a block diagram showing an example of the hardware configuration of the navigation device. In Fig. 3, the navigation device 300 includes a CPU 301, a ROM 302, a RAM 303, a magnetic disk drive 304, a magnetic disk 305, an optical disk drive 306, an optical disk 307, an audio I / F (interface) 308, a microphone 309, a speaker 310, an input device 311, a video I / F 312, a display 313, a communication I / F 314, a GPS unit 315, various sensors 316, and a camera 317. The components 301 to 317 are connected to each other via a bus 320.

[0024] The CPU 301 is responsible for the overall control of the navigation device 300. The ROM 302 stores a boot program and an information processing program. The RAM 303 is used as a work area for the CPU 301. That is, the CPU 301 is responsible for the overall control of the navigation device 300 by executing various programs stored in the ROM 302 while using the RAM 303 as a work area.

[0025] The magnetic disk drive 304 reads data from the magnetic disk 305 under the control of the CPU 301. The magnetic disk 305 records data written under the control of the magnetic disk drive 304. As the magnetic disk 305, for example, a HD (hard disk) or a FD (flexible disk) can be used.

[0026] Further, optical disk drive 306 controls reading / writing of data from / to optical disk 307 under the control of CPU 301. Optical disk 307 is a removable recording medium from which data is read under the control of optical disk drive 306. A writable recording medium can also be used as optical disk 307. In addition to optical disk 307, MO, memory card, etc. can be used as the removable recording medium.

[0027] Examples of information recorded on the magnetic disk 305 and the optical disk 307 include map data, vehicle information, road information, driving history, etc. The map data is used when searching for a route in a car navigation system, and is vector data including background data representing features such as buildings, rivers, the ground surface, and energy supply facilities, and road shape data representing the shape of roads with links, nodes, etc.

[0028] The audio I / F 308 is connected to a microphone 309 for audio input and a speaker 310 for audio output. The audio received by the microphone 309 is A / D converted within the audio I / F 308. The microphone 309 is installed, for example, on the dashboard of the vehicle, and the number of microphones may be one or more. Audio obtained by D / A converting a predetermined audio signal within the audio I / F 308 is output from the speaker 310.

[0029] Examples of the input device 311 include a remote control, a keyboard, a touch panel, etc., which are provided with a plurality of keys for inputting characters, numbers, various instructions, etc. The input device 311 may be realized in any one form of a remote control, a keyboard, or a touch panel, but may also be realized in a plurality of forms.

[0030] The video I / F 312 is connected to the display 313. Specifically, the video I / F 312 is composed of, for example, a graphic controller that controls the entire display 313, a buffer memory such as a VRAM (Video RAM) that temporarily records image information that can be displayed immediately, and a control IC that controls the display 313 based on image data output from the graphic controller.

[0031] Various data such as icons, cursors, menus, windows, characters, images, etc. are displayed on the display 313. As the display 313, for example, a TFT liquid crystal display, an organic EL display, etc. can be used.

[0032] The camera 317 captures video of the inside or outside of the vehicle. The video may be either a still image or a video. For example, the camera 317 captures the outside of the vehicle, and the captured image is analyzed by the CPU 301 or output to a recording medium such as the magnetic disk 305 or the optical disk 307 via the video I / F 312.

[0033] The communication I / F 314 is connected to a network via wireless communication and functions as an interface between the navigation device 300 and the CPU 301. Examples of communication networks that function as networks include in-vehicle communication networks such as CAN and LIN (Local Interconnect Network), public line networks, mobile phone networks, DSRC (Dedicated Short Range Communication), LAN, and WAN. The communication I / F 314 may be, for example, a public line connection module, an ETC (non-stop automatic toll payment system) unit, an FM tuner, a VICS (Vehicle Information and Communication Systems), or the like. tion and Communication System (registered trademark) / beacon receiver, etc.

[0034] The GPS unit 315 receives radio waves from GPS satellites and outputs information indicating the current position of the vehicle. The output information of the GPS unit 315, together with output values ​​of various sensors 316 described later, is used when the CPU 301 calculates the current position of the vehicle. The information indicating the current position is, for example, information that identifies a point on map data, such as latitude, longitude, and altitude.

[0035] Furthermore, the CPU 301 has a map matching function for correcting information indicating the current position so that it matches the roads in the map data while the vehicle is traveling, and displaying the corrected position.

[0036] Various sensors 316 output information for determining the position and behavior of the vehicle, such as a vehicle speed sensor, an acceleration sensor, an angular velocity sensor, and an inclination sensor. The output values ​​of the various sensors 316 are used by the CPU 301 to calculate the current position of the vehicle and the amount of change in speed and direction.

[0037] (Server configuration example) Fig. 4 is a block diagram showing an example of the hardware configuration of a server. The server 400 constituting the information recording device 100 has the same configuration as the navigation device 300 shown in Fig. 3, and is shown with different reference numerals. Note that the server 400 does not require the GPS unit 315, various sensors 316, camera 317, etc. shown in Fig. 3.

[0038] 1 realizes the information recording function (the acquisition unit 101, association unit 102, and output unit 103 in FIG. 1) by having a CPU 401 execute a predetermined program using programs and data recorded in a ROM 402 or the like provided in a server 400. A database of information associating roads with destinations, statistical information obtained by performing predetermined statistical processing, and the like is stored in a magnetic disk 405 or the like of the server 400. The server 400 also communicates with the navigation device 300 via a communication I / F 414, and outputs statistical information to the navigation device 300 in response to an acquisition request from the navigation device 300.

[0039] The server 400 may also have map information based on a digital map, and may have a function of searching for a route for each navigation device 300 and acquiring point information for each point on the map. The route search function searches for a route to a destination based on the current position of the vehicle and the destination. The point information function acquires information about the destination (coordinates on the digital map (latitude and longitude, etc.)), such as information about facilities at the destination (facility name, address, telephone number, facility opening hours, etc.). The server 400 then acquires the destination of each navigation device 300 and information about the roads used to travel to the destination, and associates these destinations with the roads.

[0040] Furthermore, the server 400 may have the map matching function described above in relation to the navigation device 300. If the server 400 is configured to perform map matching and transmit the route to the destination to the navigation device 300, the processing load on the navigation device 300 can be reduced, and the navigation device 300 can display the route to the destination simply by displaying the information distributed from the server 400, allowing the use of a simplified configuration.

[0041] The server 400 performs, broadly speaking, A. an information recording process of collecting information from the navigation device 300 and performing statistical processing, and B. an information output process of outputting the statistically processed information to the navigation device 300 in response to an acquisition request from the navigation device 300.

[0042] (A. Information recording and processing example) FIG. 5 is a flowchart showing an example of the information recording process. The process performed by the server 400 and the process performed by the server 400 are described. First, the navigation device 300 accumulates travel history information during travel and route information during route search. Travel history information is information that associates travel time with travel position. Travel position is, for example, saved as latitude and longitude (x, y coordinates) at regular intervals (for example, every second) and associated with travel time.

[0043] The route information includes the departure time from the departure point, the position of the departure point, the position of the destination, the name of the facility at the destination, etc. The route information is stored when the navigation device 300 searches for a route, when route guidance starts, when route guidance is edited, when a certain time has passed, when the user arrives at the destination, etc.

[0044] Then, the navigation device 300 transmits the accumulated movement history information and route information as travel history data to the server 400 (step S501). The transmission may be performed every time the moving object arrives at the destination, or multiple pieces of movement history information and route information may be transmitted at predetermined regular intervals.

[0045] The server 400 stores the travel history data in a database each time it is transmitted from the navigation device 300 (step S502). Then, the server 400 reads predetermined travel history data from the database (step S503) and performs map matching processing (step S504).

[0046] In this map matching process, based on the movement history information in the driving history data, road information on the map data is used to identify which roads the mobile object has been traveling on, and the processing results are stored in the database (step S505).

[0047] In the above map matching process, the map data, which is made up of digital data in which each row of travel history information is registered as a line segment between intersections, is used to search for the relevant line segment (road). If the route of the road on the matched map data is not a one-way road or has separate inbound and outbound lanes, the travel direction is calculated using information from two or more records of travel history information, or the travel direction of the moving object is specified based on travel direction information transmitted in advance from the navigation device 300. The data saved in step S505 as a result of the map matching process includes the line segment ID of the map data, the user ID (such as the identifier of the navigation device 300), the travel time, the travel direction (upward / downward), etc.

[0048] The server 400 also reads route information from the database (step S506), and based on the route information, identifies the starting point and the destination (and the facility) for the departure and arrival of the mobile object, as well as the start and end times of the movement. Then, the server 400 stores the processing results in the database (step S507).

[0049] In the destination specification process, the time when route guidance to the destination started and the time when route guidance ended are extracted for each navigation device 300 from the route guidance information. At this time, if the end time of the route guidance is not clear, the latest time for the same destination as when the route guidance started and for which there is no other destination in between in the chronological order is used. The data saved in step S507 as the result of the destination specification process includes the user ID, the name of the destination facility, the destination position, the guidance start time, the guidance end time, etc.

[0050] (B. Example of information output processing) 6 is a flowchart showing an example of information output processing, which describes processing performed by the navigation device 300 and processing performed by the server 400. First, the navigation device 300 specifies an acquisition request (step S601).

[0051] In response to the acquisition request from the navigation device 300, the server 400 extracts the route guidance history of the corresponding road from the database (step S602). Then, the server 400 calculates the number of unique users for each destination (the number of users who arrived at the destination) and the number of times all users traveled to the destination (step S603).

[0052] Then, the destinations are sorted in descending order of the number of unique users (step S604), and the sorted destinations are output to the navigation device 300 as ranking information (step S605).

[0053] The navigation device 300 receives the ranking information (step S606), displays the received ranking information on the display 313 (step S607), and ends the series of processes.

[0054] As the above process, the user, via the navigation device 300, 1. Destination ranking by road 2. Request road rankings for each facility.

[0055] 1. In the case of destination ranking for each road, the user specifies an arbitrary road via the navigation device 300, and the server 400 generates and provides destination ranking information for the specified road by the above-mentioned process.

[0056] In addition, in the case of 2. ranking of roads by facility, the user specifies any facility via the navigation device 300, and in the processing of steps S603 and S604, the server 400 tallys up the roads traveled with the specified facility as the destination, and outputs the roads sorted in order of the number of users to the navigation device 300 as ranking information.

[0057] (Extracting the movement history of moving objects) Next, the extraction process of information used as a movement history when a mobile object of a certain user (user ID: 131425) moves will be described. FIG. 7 is a diagram showing the movement state of a mobile object. The black circles (●) in FIG. 7 are the positions of the mobile object when it moves, and the white circles (○) are the positions of the mobile object when it is guided to a route. The dotted lines indicate road data in the map data, and the solid lines are route guidance sections in the road data. Route guidance starts at the start point 701 of the route guidance (corresponding to the departure point), and the end point 702 is the destination. Note that the positions of the mobile object in the diagram are positions (coordinates) after map matching. Note that "i01" to "ni02" are assigned to each link of the road as the line segment ID of the map data.

[0058] Fig. 8 is a chart showing route guidance information, Fig. 9 is a chart showing a movement history, and Fig. 10 is a chart showing a result of map matching. These Figs. 8 to 10 correspond to the movement history during the movement of the mobile object shown in Fig. 7.

[0059] When searching for a route, the navigation device 300 transmits route guidance information including a departure time, a departure point (departure point coordinates), a destination such as a facility (destination point coordinates), and a destination point name (facility name) to the server 400. Then, the vehicle moves according to the route searched for within the navigation device 300.

[0060] The server 400 acquires route guidance information 800 shown in Fig. 8 from the navigation device 300. Then, from the database, of the movement history information 900 shown in Fig. 9, it scans the movement history 900 of the moving object from departure time (2013 / 1 / 28 12:00:03) t onward, and stops scanning when it reaches coordinates xy within a predetermined threshold value of the destination coordinates (latitude 139.7646, longitude 35.6776). Then, the server 400 scans from time t to coordinates xy. The travel history of the moving object within the range is set as a route guidance section 901, and map matching processing is performed on this route guidance section 901.

[0061] In the map matching process, the spatial connection between the movement coordinates and the roads (links) on the map data is determined, and the traveling direction of the moving object is calculated based on the change between two points of different coordinates (or times) in the movement history information 900. Then, map matching result information 1000 shown in FIG. 10 is generated and stored in a database. The map matching result information 1000 includes a user ID (e.g., an identifier of the navigation device 300, etc.), a line segment ID (each link in FIG. 7), a travel time, and a traveling direction (uphill / downhill). As a result, information on the roads traveled in the route guidance section for each user's route guidance to the destination, including the traveling direction, can be determined and stored in a database.

[0062] Also described is the extraction process of information used as a movement history when a moving object of a different user (user ID: 254245) moves. Fig. 11 is a diagram showing the movement state of the moving object, Fig. 12 is a diagram showing route guidance information, and Fig. 13 is a diagram showing the result of map matching. Similarly to the above, map matching result information 1000 for the route guidance section to the destination is generated for this user as well.

[0063] Then, in correspondence with the different user, a record 1201 is added to the route guidance information 800 in Fig. 12. Also, a record 1301 relating to this user is added to the map matching result information 1000 in Fig. 13.

[0064] (Example of statistical processing of destination rankings by road) 14 is a flowchart of a destination ranking process for each road as an example of information output processing. The above-mentioned 1. An example of the statistical processing of destination ranking for each road will be described. First, the server 400 acquires the travel history 900 including the relevant road based on an acquisition request (destination ranking for each road) from the navigation device 300 (step S1401). Then, the server 400 specifies the road ID corresponding to the requested road from the map matching result information 1000 (step S1402).

[0065] In the illustrated example, the line segment ID corresponding to the specified road is "I02", and information about this road is extracted from the map matching result information 1000. Then, this map matching result information 1000 is combined with the route guidance information 800, and facility information is added (step S1403). This combination associates the destinations arrived at for each user who traveled along the corresponding road. In the illustrated example, of the two users who traveled along the road (line segment ID: I02), one is traveling uphill and has a destination (facility) of the International Forum, and the other is traveling downhill and has a destination (facility) of Amusement Park A.

[0066] Thereafter, the number of users who arrived at the destination (visited the facility) and the number of visits are counted as ranking information 1400 for each road (step S1404), and this ranking information 1400 is output to the user's navigation device 300 as a statistical result (step S1405).

[0067] This allows the user to obtain information on the number of users and the number of visits to a destination (facility) that has been reached by traveling along a certain road. If the user specifies other items in the acquisition request, such as the direction of travel along the road, information on destinations by the direction of travel along the road can be obtained from the ranking information 1400. If the user specifies a time, information on destinations by travel time (or time period) along the road can be obtained from the ranking information 1400.

[0068] In addition, for 2. Road ranking by facility, the route is calculated by using the facility as a key in the same way as above. The guidance information is combined with the map matching results of the movement history of arrival at the facility to extract the corresponding roads. Then, for each facility, statistical processing is performed to rank the roads traveled with the facility as the destination, and the results are output to the user's navigation device 300.

[0069] In the above embodiment, the server 400 performs the map matching process, but the navigation device 300 may perform the map matching process and output the movement history after map matching to the server 400. Furthermore, the function of the server 400 may be performed by a certain navigation device 300, in which case the server 400 may be unnecessary.

[0070] Although the configuration in which the movement history of the moving object is output to the server using the navigation device has been described, other information processing devices such as a smartphone may be used, or a personal computer installed in the user's home or facility may be used.

[0071] In addition, facility managers will be able to obtain statistical information on which roads customers took to visit the facility. Based on the road ranking for each facility mentioned above (2), the statistical information can be used effectively for promotional purposes, such as by erecting billboards along roads with high rankings or distributing electronic coupons.

[0072] In addition, the user is not limited to using the navigation device 300 described in the embodiment, but may use a simpler configuration. For example, by using an information acquisition device having a GPS function capable of acquiring the current location on the user's terminal, a communication function (transmission / reception unit) with the server 400, and a display function, the user can receive an information output service from the server 400 by transmitting an acquisition request to the server 400 in the same manner as in the above embodiment. In this case, the server 400 side receives information on the current location and destination of the user's information acquisition device and searches for a travel route to the destination. The server 400 then transmits this travel route to the information acquisition device one by one. The information acquisition device displays statistical information on the received route and destination and notifies the user. In this way, even if an information acquisition device with simple functions is used, the information output service similar to that of the embodiment can be received.

[0073] According to the embodiment described above, the movement history of a mobile object is stored in a database in association with a destination, and statistical information on the destination can be output in response to an acquisition request from a user. This makes it possible to obtain information on the destination where a mobile object that has traveled along a certain road has arrived, and on the roads traveled when visiting the destination (facility).

[0074] For example, it is possible to know the statistics of which destination (facility) a moving body traveling on a certain road is heading for, and to know the popular facilities on the road currently being traveled. In particular, on roads such as expressways where you cannot change direction every few kilometers until you reach an interchange, the destinations reached on the uphill and downhill directions are significantly different even on the same road, and the tendency of the number of times a facility is set as a destination is also significantly different. With the above configuration, it is possible to present a ranking of destinations according to the direction of travel on the road, making it possible to provide more detailed information.

[0075] The information processing method described in the present embodiment can be realized by executing a prepared program on a computer such as a personal computer or a workstation. This program is recorded on a computer-readable recording medium such as a hard disk, a flexible disk, a CD-ROM, an MO, or a DVD, and is executed by being read from the recording medium by the computer. This program may also be a transmission medium that can be distributed via a network such as the Internet. [Explanation of symbols]
