[First embodiment]
Hereinafter, a first embodiment of the present invention will be described with reference to FIGS.

  FIG. 1 is a system configuration diagram of a communication system including an information processing apparatus 100 according to the present embodiment. As shown in FIG. 1, the information processing apparatus 100 is a server computer connected to a network 300 such as the Internet or a dedicated line. Similarly to the information processing apparatus 100, when the mobile terminal 200 connected to the network 300 in a wired or wireless manner (mobile terminals 200A to 200D are collectively referred to as the mobile terminal 200) is set to be communicable with each other. A communication system is configured.

First, the outline of the communication system will be described.
The communication system is a system that provides a service that uses location information transmitted from a user. Specifically, the information processing apparatus 100 included in the communication system determines the user's travel route using the user's position information, and the route information that is the result of the determination is displayed on the user's mobile terminal 200. To the map. The information processing apparatus 100 not only uses this movement route in a plane but also in a place where a plurality of routes such as general roads and highways are running in parallel vertically (hereinafter referred to as determination target sections), etc. In order to three-dimensionally determine which route the user has passed, barometric pressure information that is data representing the barometric pressure value measured from the mobile terminal 200 is used.

  The portable terminal 200 is a portable terminal device that can be carried by the user and has a function of uploading position information obtained by measuring the current position and atmospheric pressure information at predetermined time intervals or based on user input. Specifically, a mobile phone, a smart phone, a notebook PC, a PDA, etc. are mentioned, for example. Although not shown in FIG. 1, the mobile terminal 200 includes a main control unit including a CPU and a memory 113, a communication unit for connecting to the network 300, an input unit such as a touch panel that receives an operation from a user, and a display for displaying a screen. A positioning unit such as a GPS function for positioning the current position information, a pressure sensor for positioning the current atmospheric pressure information, and the like. In addition, in this embodiment, although a user demonstrates as what accesses the information processing apparatus 100 using the portable terminal 200, the terminal which a user uses does not necessarily need to provide portability, for example, an in-vehicle terminal etc. Also good.

  Each configuration of the information processing apparatus 100 will be described with reference to FIG. FIG. 2 is a block diagram of the information processing apparatus 100. As illustrated in FIG. 2, the information processing apparatus 100 includes a control unit 110, an input unit 120, a storage unit 130, and a communication unit 140.

  The control unit 110 includes an arithmetic processing unit 111 such as a CPU or MPU, an image processing unit 112, and a memory 113 such as a RAM. The arithmetic processing unit 111 operates various functional units by executing a program recorded in the storage unit 130 based on various inputs. This program may be stored in a storage medium such as a CD-ROM, or distributed via the network 300 and installed in a computer. The memory 113 is for temporarily storing a server program, a game program, and various types of data necessary for calculation during execution of processing in these programs.

  The image processing unit 112 generates an image to be transmitted to the user's mobile terminal 200. The image processing unit 112 desirably creates an image related to a map displayed on the mobile terminal 200 and a movement route displayed on the map. Existing techniques can be used to create these images.

  The input unit 120 indicates a keyboard, a mouse, a touch panel, or the like, and receives an operation from an administrator of the information processing apparatus 100.

  The storage unit 130 is configured by a storage device such as a hard disk, and records various programs necessary for executing processing in the control unit 110, data necessary for executing various programs, and the like. Specifically, the storage unit 130 preferably includes a user information table 130A, a network information table 130B, and an atmospheric pressure information table 130C. 3A shows the user information table 130A, and FIG. 3B shows the network information table 130B. FIG. 3C shows the atmospheric pressure information table 130C. For example, in the user information table 130A, as shown in FIG. 3A, the user ID, the atmospheric pressure information ID, the user position information, the position information, and the time when the atmospheric pressure information is acquired (acquisition time) are stored in association with each other. It is desirable that Further, it is desirable that information regarding roads is stored in the network information table 130B in units of routes. As shown in FIG. 3B, the network information table 130B includes position information indicating the route ID and route range, altitude, an identifier (group ID) of an atmospheric pressure group (to be described later), and an atmospheric pressure classified into each group. The period (predetermined period) during which information is acquired may be stored in association with each other. Further, as shown in FIG. 3C, the atmospheric pressure information table 130C may store the atmospheric pressure information ID, the atmospheric pressure value, and the atmospheric pressure group ID in association with each other.

  Returning to FIG. 2, the continuation of the configuration of the information processing apparatus 100 will be described. The communication unit 140 is for connecting the information processing apparatus 100 to the network 300. For example, the communication unit 140 may include a LAN card, an analog modem, an ISDN modem, and the like, and an interface for connecting them to the processing unit via a transmission line such as a system bus.

  Furthermore, as illustrated in FIG. 2, the arithmetic processing unit 111 includes, as function units, an atmospheric pressure information acquisition unit 111A, a classification unit 111B, a route determination unit 111C, and an output unit 111D.

  The atmospheric pressure information acquisition unit 111A acquires atmospheric pressure information from the user. Specifically, the atmospheric pressure information acquisition unit 111A acquires atmospheric pressure information of a user determined to have passed around the determination target section from the position information, and stores the ID of the atmospheric pressure information in the user information table 130A of the storage unit 130. The positional information, the acquisition source user ID, and the acquisition time are stored in association with each other, and the atmospheric pressure information table 130C stores the atmospheric pressure information ID and the atmospheric pressure value in association with each other. It is preferable that the atmospheric pressure information acquisition unit 111A acquires atmospheric pressure information from a user who is moving at a speed equal to or higher than a certain speed. Thereby, acquisition object can be narrowed down to the atmospheric pressure information from the user who is moving by car. In other words, since the user who is walking around the determination target section can be excluded from the acquisition target, it is possible to improve the accuracy of the route determination when the determination target route is a car-only road. Become.

  The classification unit 111B has a group classification function and a correspondence determination function. The group classification function is a function for classifying the atmospheric pressure information stored in the atmospheric pressure information table 130C into a plurality of groups. Specifically, with reference to the user information table 130A, a predetermined period is determined based on the time when the user who is the determination target of the movement route passes around the determination target section, and a plurality of pieces of information that have passed around the determination target section around this predetermined period. Is a function for acquiring and classifying the atmospheric pressure information of the user from the atmospheric pressure information table 130C. For example, when the user passes the route to be determined at around 9:00 am on February 10, 2013, the classification unit 111B uses the group classification function to start from 8:00 am on February 10, 2013, which is the same day. It is good also as what classifies the atmospheric pressure information on a plurality of users who passed around the judgment object section by 9:59:59 am. The period to be classified at this time may be, for example, the same time on the same day in the past several years, or the same time in the same season in the same year.

  Further, for example, when the determination target section is one in which two routes are parallel in the vertical direction, the classification unit 111B classifies the atmospheric pressure information into two groups based on the level of the atmospheric pressure value, and five roads Are parallel, the classification unit 111B desirably classifies the atmospheric pressure information into groups corresponding to the number of paths that are three-dimensionally parallel. For this classification, a clustering technique based on the atmospheric pressure value can be used.

  The classification unit 111B may classify the atmospheric pressure information of the users around the determination target section as a classification target. However, by determining only the atmospheric pressure information acquired from a plurality of users that have passed on the determination target path, the classification is performed. It is possible to improve the accuracy.

  The correspondence determination function of the classification unit 111B is a function for associating each group with each route from the relative relationship between the atmospheric pressure values of each group and the relative relationship between the altitudes of each route in the determination target section. For example, as described above, when five roads are arranged in parallel, the correspondence relationship is determined by associating groups with lower atmospheric pressure values in descending order of elevation. At this time, it is preferable that the network information table 130B of the storage unit 130 stores groups corresponding to the respective routes in a predetermined period.

  The route determination unit 111C determines to which group the atmospheric pressure information of the user is classified based on the atmospheric pressure information acquired from the user who is the target of the route determination, and refers to the correspondence between each group and each route. Thus, the movement path of the user who is the target of the path determination is determined.

  The output unit 111D outputs the determined route information. The output destination at this time may be the portable terminal 200 or another system.

  Next, a processing flow of the information processing apparatus 100 when determining a route will be described with reference to FIG. At this time, in the determination target section, as shown in FIG. 5, two routes of a general road 501 having a relatively low altitude and a highway 502 having a relatively high altitude are parallel. In this example, it is assumed that the user U1 who is a target of route determination passes through this determination target section at 15:00 on March 4, 2013. Each processing step included in the processing flow described below can be executed in any order or in parallel as long as there is no contradiction in the processing contents. These steps may be added. Further, a step described as one step for convenience can be executed by being divided into a plurality of steps, while a step described as being divided into a plurality of steps for convenience can be grasped as one step.

  The user U1 has the portable terminal 200A and transmits position information and barometric pressure information to the information processing apparatus 100 as needed at predetermined intervals or by input from a user or an application. The arithmetic processing unit 111 determines whether or not the user U1 is passing the determination target route based on the transmitted position information (S101). When it is determined that the user U1 is passing the determination target route (S101: YES), the classification unit 111B determines a predetermined period from the time when the position information is acquired (S102). Here, the predetermined period is described as 13:00 to 15:00 on the same day, but the predetermined period can be freely set based on the design concept of the system.

  The classification unit 111B refers to the atmospheric pressure information of other users that have passed through the determination target section from 13:00 to 15:00 on March 4, 2013, which is a predetermined period, from the user information table 130A, and based on the atmospheric pressure value It classifies into two groups (S103). FIG. 6 is a diagram schematically showing how the atmospheric pressure information is classified into two by clustering. Group A in FIG. 6 indicates a group having a high atmospheric pressure value, and group B indicates a group having a low atmospheric pressure value. Based on the result of this classification, the ID of the group to which each piece of atmospheric pressure information belongs is recorded in the atmospheric pressure information table 130C of the storage unit 130.

  Next, the classification unit 111B compares the relative relationship between the atmospheric pressure values of the groups A and B with the relative relationship between the altitudes of the highway 502 and the general road 501, and compares the relative relationship with the group having a relatively low atmospheric pressure value. The route with a higher altitude is associated. Specifically, the classification unit 111B associates the group B with the expressway 502, and associates the group A with the general road 501 and determines the correspondence (S104). At this time, the network information table stores the IDs of the groups having a corresponding relationship with each route during a predetermined period.

  When the correspondence relationship is determined, the route determination unit 111C determines whether the atmospheric pressure information of the user U1 acquired by the atmospheric pressure information acquisition unit 111A is included in which group A or group B of the atmospheric pressure information of the user U1. A determination is made based on the atmospheric pressure value (S105). As a result of the determination, if it is determined that the atmospheric pressure information of the user U1 is included in the group B, it is determined that the user U1 passes the highway 502 (S106). On the other hand, when it is determined that the atmospheric pressure information of the user U1 is included in the group A, it is determined that the determination target user passes through the general road 501 (S107).

  Based on the determination result, the output unit 111D outputs the route information of the user U1 to the mobile terminal 200A (S108).

  Thus, since the present invention uses the relative relationship of the barometric pressure information acquired from a plurality of users when determining the movement route, for example, unlike the method of determining altitude with a barometer, the standard barometric pressure is used. It is possible to determine the user's travel route without using.

[Second Embodiment]
The second embodiment of the present invention will be described below with reference to FIGS.
FIG. 7 is a block diagram of the information processing apparatus 100 according to the second embodiment. As shown in FIG. 7, in this embodiment, it is desirable that the arithmetic processing unit 111 further includes an area dividing unit 111E.

  The area dividing unit 111E is a unit that divides a route included in the determination target section into predetermined areas. The area dividing unit 111E may be divided at a point where the routes intersect and the level is changed to form an area, or may be divided at a predetermined distance to form the area. For example, as shown in FIG. 8, in the determination target section, when each route intersects three-dimensionally and the altitude is interchanged, the area dividing unit 111E divides and forms the area at the point where the altitude is interchanged. It is desirable to do. Thereby, for example, when the altitude of each route is switched in the determination target section, it is possible to determine which route the user has passed for each area.

  Information on the divided areas (such as latitude and longitude) is stored in the network information table 130B of the storage unit 130. At this time, in the second embodiment, the classification unit 111B desirably classifies the atmospheric pressure information in area units. The classification unit 111B compares the atmospheric pressure values for each divided area and classifies the atmospheric pressure information, thereby improving the accuracy of association between the route and the group.

  Next, a processing flow of the information processing apparatus 100 in the present embodiment when the user U1 passes the route illustrated in FIG. 10 will be described with reference to FIG. In FIG. 10, since the altitude of each route is not interchanged in the determination target section, each route is divided into three areas 601 to 603 at a predetermined distance. As shown in FIG. 10, the determination target section includes three roads: a highway 503 having a relatively high altitude, a highway 502 having a relatively high altitude, and a general road 501 having a relatively low altitude. Includes one route. Each of the three paths is inclined. In the highway 503, the altitude in the area 602 corresponds to the altitude in the area 601 of the highway 502, and the area 603 corresponds to the altitude in the area 602 of the highway 502. In the highway 502, the altitude in the area 602 corresponds to the altitude in the area 601 of the general road 501, and the altitude in the area 603 corresponds to the altitude in the area 602 of the general road 501.

  It is assumed that the user U1 who is a target of route determination passes through this determination target section at 15:00 on March 4, 2013. Each processing step included in the processing flow described below can be executed in any order or in parallel as long as there is no contradiction in the processing contents. These steps may be added. Further, a step described as one step for convenience can be executed by being divided into a plurality of steps, while a step described as being divided into a plurality of steps for convenience can be grasped as one step.

  When the arithmetic processing unit determines that the user U1 has passed the determination target section (S201: YES), the classification unit 111B determines a predetermined period (S202), and is acquired on the determination target route within the predetermined period. The barometric pressure information of the plurality of other users is clustered in units of areas and classified into three groups (S203).

  FIG. 11 is a diagram schematically illustrating how the classification unit 111B in the divided areas classifies the atmospheric pressure information. The areas 601 to 603 correspond to the areas 601 to 603 in FIG. 10 respectively. There are two groups.

  In this case, the classification unit 111B determines that the groups E1 to E3 having the lowest atmospheric pressure values have the relatively high altitude road 503 and the groups D1 to D3 having the relatively middle atmospheric pressure values are relatively It is determined that the highway 502 having an intermediate altitude and the groups C1 to C3 having the highest atmospheric pressure have a corresponding relationship with the general road 501 having the lowest altitude (S204). Thus, for each area into which the classification unit 111B is divided, the altitude of each route is not constant by comparing the relative relationship between the atmospheric pressure values of each group and the relative relationship between the altitudes of each route. Even in this case, the correspondence between the group and the route can be determined.

  Next, the path determination unit 111C determines in which group the atmospheric pressure information of the user U1 is contained most (S205). In FIG. 11, atmospheric pressure information U11, U12, and U13 indicate atmospheric pressure information acquired from the user U1. As shown in FIG. 11, the atmospheric pressure information U11 is included in the group C1, the atmospheric pressure information U12 is included in the group D2, and the atmospheric pressure information U13 is included in the group C3. Since the three routes of the determination target section are not interchanged, the deviation is considered to be caused by an error in the atmospheric pressure information. As described above, depending on the accuracy of the pressure sensor included in the mobile terminal 200, an error may occur in the atmospheric pressure value of the acquired atmospheric pressure information, and the classification may not be performed correctly. In such a case, the route determination unit 111C estimates that the route having the larger number of times the atmospheric pressure information acquired from the user U1 has been acquired is acquired. For example, when the atmospheric pressure information acquired from the user U1 is the most contained in the group C, it is determined that the general road 501 has been passed (S206). In the case of group D, it is determined that the vehicle has passed through the expressway 502 (S207), and in the case of group E, it is determined that the vehicle has passed through the expressway 503 (S208). In the example of FIG. 11, the route determination unit 111 </ b> C determines that the user U <b> 1 has passed the general road 501 because the group C corresponding to the highway 503 includes more. Based on the route determined by the route determination unit 111C, the output unit 111D outputs the route information to the mobile terminal 200A of the user U1 (S209).

  Other configurations and functions are the same as those in the first embodiment.

[Other embodiments]
As mentioned above, although embodiment of this invention was described, this invention is not limited to above-mentioned embodiment, Based on the technical idea of this invention, a various deformation | transformation and change are possible.

  For example, in the above-described embodiment, the classification unit 111B is configured to perform clustering by clustering the user's barometric pressure information as one point. However, the present invention is not limited to this, and, for example, clustering may be performed for each user using a transition of atmospheric pressure information as a line. FIG. 12 is a diagram showing the atmospheric pressure information acquired from the users U1, U2, and U3. The vertical axis represents the atmospheric pressure value, and the horizontal axis represents the position on the measured path. As shown in FIG. 12, the atmospheric pressure information of each user is connected by a line and represented as a broken line. At this time, it is desirable that the classification unit 111B performs clustering based on a parameter such as an inclination representing a broken line of each user. Thereby, since the atmospheric pressure information is classified as a set along each route, it is possible to improve the accuracy when determining the correspondence. Furthermore, the classification unit 111B may be configured to limit the target for classifying the atmospheric pressure information to the atmospheric pressure information of the user who is moving in the same direction as the user who is the target of the route determination.

  In addition, it is possible to determine whether a pedestrian is on the ground or in an underground city, for example, as a determination target in addition to a road.
