However, in the present embodiment, by selecting the destination on the display unit 10b of the mobile terminal 10 with the GPS & image acquisition device 10c, the optimum route from the current position to the destination and the user possesses at that time The page number describing the optimum route on the road map can be displayed on the display unit 10b.

  The position recognition system according to the present embodiment includes a mobile terminal 10 with a GPS & image acquisition device 10c, a position recognition device 40 provided in a mobile terminal supplier data center 30, and a GPS 50. The mobile terminal 10 with the GPS & image acquisition device 10c is mainly intended for GPS receivers and camera-equipped mobile phones, and the position recognition function by the GPS receiver, the image acquisition function by the camera 10c, the information display function by the display unit 10b, and A communication function is provided via the communication lines 60a and 60b with the position recognition device 40A provided in the portable terminal provider data center 30 using the communication unit 10a. To the road map 20 published as a book, an identification code is added to the road map ID (ID for identifying the product name of the road map) using a two-dimensional barcode 20a or the like. The position recognition device 40A provided in the portable terminal supplier data center 30 includes digital data 45a corresponding to a plurality of published road maps.

  FIG. 12 shows a detailed configuration diagram of the position recognition device 40A. The position recognition device 40A in the present embodiment is connected to the communication interface 42 and communicates with the mobile terminal 10 with the GPS & image acquisition device 10c via the communication lines 60a and 60b, a CPU 44, and a memory 45. And. The communication interface 42, the CPU 44, and the memory 45 are connected by a bus line 43. The memory 45 stores road map digital data 45a obtained by directly converting the map information of a plurality of road maps 20 published as books into digital data, a road map position recognition program 45b, and a road map route search program 45c. is doing.

  Next, an operation flow in the present embodiment is shown based on FIG.

  When the position recognition system according to the present embodiment is activated, the mobile terminal 10 with the GPS & image acquisition device 10c reads the two-dimensional barcode 20a added to the road map 20 using the image acquisition device 10c provided. Road map ID data 80a is acquired. Further, the GPS signal 70 transmitted from the GPS 50 is received via the communication unit 10a (step S21). As a result, the mobile terminal 10 with the GPS & image acquisition device 10c identifies the GPS geodetic data 80b based on the GPS signal 70 indicating the current position of the user and the product name of the road map 20 owned by the user on the spot. The possible road map ID data 80a is stored.

  Next, the road map ID data 80a and the GPS geodetic data 80b acquired in step S21 from the mobile terminal 10 with the GPS & image acquisition device 10c are arranged in the mobile terminal supplier data center 30 via the communication line 60a. It is transmitted toward the position confirmation device 40A (step S22). When the position recognition system 1 is activated, the position recognition device 40 </ b> A provided in the portable terminal supplier data center 30 starts the operation of the CPU 44 and reads and executes the road map position recognition program 45 b stored in the memory 45. When the road map position recognition program 45b is executed, the position recognition device 40A communicates the road map ID data 80a and the GPS geodetic data 80b transmitted from the portable terminal 10 with the GPS & image acquisition device 10c via the communication line 60a. Received by the unit 41. When the road map ID data 80a is captured by the CPU 44, the CPU 44 reads the road map digital data 45a stored in the memory 45 and searches for digital data corresponding to the road map ID data 80a. Then, by comparing the corresponding digital data with the GPS geodetic data 80b, the current position of the portable terminal 10 with the GPS & image acquisition device 10c on the corresponding digital data, that is, the current position of the user is determined (step S23). When the position recognition device 40A determines the current position of the user on the corresponding digital data, the position recognition device 40A transmits the digital data indicating the current position of the user from the communication unit 41 via the communication line 60b. Among them, the electronic data 90b of the section area range that can be displayed on the display unit 10b of the mobile terminal 10 with the GPS & image acquisition device 10c is transmitted to the mobile terminal 10 with the GPS & image acquisition device 10c. Further, the page number on the road map 20 corresponding to the electronic data 90b in the section area and the section number data 90a are simultaneously transmitted to the mobile terminal 10 with the GPS & image acquisition device 10c (step S24). The mobile terminal 10 with the GPS & image acquisition device 10c receives the electronic data 90b of the division area range, the page number on the road map 20 corresponding to the electronic data 90b of the division area, and the division number data 90a by the communication unit 10a. As in the first and second embodiments, the received data is displayed on the display unit 10b as shown in FIG. 5 (step S25). Accordingly, the user can display the electronic map image showing the current position displayed on the display unit 10b of the mobile terminal 10 with the GPS & image acquisition device 10c, the page number on the road map 20 corresponding to the electronic map image, and the section. Referring to the numbers, as shown in FIG. 6, the current position can be easily recognized on the paper.

  In the present embodiment, the destination point on the display unit 10b of the mobile terminal 10 with the GPS & image acquisition device 10c is further based on the current position displayed on the display unit 10b of the mobile terminal 10 with the GPS & image acquisition device 10c. Desired destination information is registered in the portable terminal 10 with the GPS & image acquisition device 10c by designating or inputting a destination name. The mobile terminal 10 with the GPS & image acquisition device 10c transmits the registered destination information to the position recognition device 40A via the communication unit 10a (step S26). When the position recognition device 40A receives the destination information via the communication unit 41, the CPU 44 reads the road map route search program 45c from the memory 45 and executes it. When the road map route search program 45c is executed, the CPU 44 searches for the optimum route from the current position to the destination on the corresponding digital data based on the current position information and the destination information. Further, the page number in the road map 20 corresponding to the searched optimum route is searched. Then, the position recognition device 40A transmits the optimal route and the page number information on the road map 20 corresponding to the optimal route to the mobile terminal 10 with the GPS & image acquisition device 10c via the communication unit 41 (step). S27). The mobile terminal 10 with the GPS & image acquisition device 10c receives the page number information in the road map 20 corresponding to the optimum route and the optimum route by the communication unit 10a. Then, the optimum route from the current position to the destination and the page number on the road map 20 corresponding to the optimum route are displayed on the display unit 10b. By referring to the page number on the road map 20, the user can easily recognize the optimum route from the current position to the destination on the road map 20 he / she owns.

  According to the present embodiment, in addition to the functions and effects of the first and second embodiments, the optimal route from the current position to the destination is displayed as a map image equivalent to a map published as a book. By displaying on the display screen and displaying which page of the map the displayed map image corresponds to, the optimum from the current position to the destination that could not be communicated by the page number alone It is possible to realize a position recognition system that allows a user to easily recognize a route.

  In the description of the present embodiment, the position recognition device 40 is provided in the mobile terminal provider data center 30, but this is provided in the road map publisher data center 100 as described in the second embodiment. May be.
