Description

  The present invention relates to information provision using electronic map data that can be displayed three-dimensionally.

  Conventionally, methods for advertising and advertising products and services have been diversified. In general, advertisements and advertisements for products and the like are performed through media such as television, radio, newspapers, magazines, or using advertising billboards. In recent years, along with the spread of the Internet, advertisements and advertisements using electronic data have also spread. Examples of advertisements / advertisements using electronic data include character advertisements displayed on Web pages, so-called banner advertisements, moving image advertisements, advertisements using three-dimensional images using computer graphics, and the like.

  By the way, since the three-dimensional image can represent the space three-dimensionally, it is used for representing a virtual space or simulating a real space. In particular, the three-dimensional image is applied to an image of a computer game, various simulation images using virtual reality, and the like. Three-dimensional images are also used in electronic maps that are digitized so as to be usable by computers. By using a three-dimensional image for an electronic map, a bird's-eye view of a city and a three-dimensional intersection can be expressed realistically. An electronic map using a three-dimensional image has an advantage that it is easy to grasp the map based on this reality.

  In recent years, it has been studied to promote and advertise on an electronic map using a three-dimensional image. In this advertisement / advertisement, it is conceivable to provide an advertising signboard on an electronic map. However, providing advertising billboards indefinitely, such as attaching a billboard different from reality, to the building, has a problem of deteriorating the displayed cityscape and reality. In particular, it is a problem that cannot be overlooked in electronic map data used in navigation devices that perform route search and route guidance. This is because if the image displayed on the navigation device is different from the sight actually seen by the user's eyes, the user feels uncomfortable or feels anxiety that the route may be wrong.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a technique for visually providing information without sacrificing reality in electronic map data that can be displayed three-dimensionally. .

In order to solve at least a part of the above-described problems, the present invention employs the following configuration.
The electronic map data supply apparatus of the present invention is
An electronic map data supply device that supplies electronic map data that can be three-dimensionally displayed to an electronic map display device,
Fixed object data for three-dimensionally displaying a fixed object actually existing on the electronic map on the electronic map;
Movable object data for three-dimensionally displaying a virtual movable object arranged with the fixed object on the electronic map on the electronic map;
Additional information data storing additional information to be visually provided to a viewer of the electronic map displayed on the display device in an integrated state with at least a part of the movable object;
An electronic map data storage unit for storing electronic map data including:
A request receiving unit for receiving a display request for electronic map data including a supply request for at least the fixed object data of the electronic map data from the display device;
A movable object display control unit for specifying a position of the movable object in a three-dimensional virtual space generated based on the electronic map data when the display request includes a supply request for the movable object data;
An electronic map data transmission unit for transmitting electronic map data including at least the fixed object data and the movable object data to the display device based on the specified position and the display request;
With
The movable object display control unit, even when the display request includes the supply request for the movable object data, when the display request does not include the supply request for the additional information data, Without specifying the position of the movable object in the three-dimensional virtual space,
The gist of the electronic map data transmission unit is to transmit electronic map data not including the movable object data and the additional information to the display device.

  Here, “electronic map data” means map data generated based on the real world, and does not include a completely virtual world map in a computer game or the like. The electronic map data includes map data representing a narrow area such as a map inside a building and a map of an underground mall, in addition to map data representing a wide area such as a national map and a city map. “Fixed object” means something that is not easily moved or changed. Examples of the fixed object include a road, a building, a signboard attached to the building, a river, a bridge, and the like. This fixed object actually exists mainly in the real world. The “movable object” means a virtual object that is not actually arranged in the real world and can be easily moved or moved. Examples of movable objects include humans, animals, traveling or parked vehicles, standing signs, aircraft, ships, ad balloons, clouds, and the like.

  In the present invention, the electronic map data includes movable object data for representing the movable object in three dimensions and additional information data in addition to the fixed object data. In the electronic map displayed three-dimensionally, the fixed object is the one that the viewer of the map pays most attention, and has a great influence on the reality. In contrast, movable objects generally do not affect reality as much as fixed objects. That is, even if a moving object different from the actual one is displayed in the electronic map data displayed three-dimensionally, the reality of the map is not impaired. In the present invention, additional information is provided in a state of being integrated with at least a part of the movable object.

  By doing so, it is possible to visually provide additional information to the viewer of the electronic map displayed on the display device without impairing the reality. Note that the additional information data and the movable object data may be prepared separately, or may be prepared integrally so as to be identifiable. Further, the additional information data and the movable object data do not necessarily correspond one-to-one. For example, one additional information data may correspond to a plurality of movable object data, or a plurality of additional information data may correspond to one movable object data.

In the above electronic map data, additional information that does not directly contribute to the display of the map includes the name of the building, topography (altitude, river length, etc.), weather (weather forecast, temperature, UV information, pollen information, etc.) ) And various other information, for example,
The additional information may be information for advertisement / advertisement.

  By doing so, it is possible to promote and advertise without losing reality.

  Moreover, it is preferable that at least one of the movable object data and the additional information data is associated with a display condition to be satisfied in order to perform display based on the data.

  By doing so, it is possible to easily extract movable object data and additional information data according to display conditions, and to effectively provide information, for example, advertisement / advertisement. Examples of display conditions include the area to be displayed, the scale, the time for using the electronic map data, the necessity of additional information data from the user, and the like.

  In addition, since the electronic map data supply device of the present invention includes the movable object display control unit, it specifies where the movable object is displayed on the map based on the display request from the display device, and the fixed object data. The electronic map data including the movable object data can be supplied to the display device. The movable object data may or may not be accompanied by the additional information data described above. The shape of the movable object itself may have a function as additional information such as advertising / advertisement.

  Further, in the electronic map data supply device of the present invention, when the display request received by the request reception unit does not include the additional information data supply request, the electronic map data transmission unit transmits the movable object data, the additional information, Since the electronic map data that does not contain is transmitted to the display device, the data size of the electronic map data transmitted from the electronic map data supply device to the display device can be reduced. Therefore, in the electronic map data supply device and the display device, it is possible to reduce a load caused by transmission / reception of the electronic map data.

In the electronic map data supply apparatus of the present invention,
Based on the data size of the electronic map data transmitted by the electronic map data transmission unit, a communication fee calculation unit that calculates a communication fee required for transmission of the electronic map data,
The communication fee calculation unit includes permission information indicating that the display request includes a supply request for the additional information data, and the supply request for the additional information data permits distribution of information for advertisement / advertisement. May be included, a discount process for discounting the communication fee may be performed.

  In this way, when the display device downloads information for advertisement / advertisement as additional information from the electronic map data supply device, the electronic map data supply device can discount the communication fee.

In any of the electronic map data supply devices described above,
The electronic data storage unit stores pay information as the additional information,
The electronic map data supply device further includes:
When the display request includes a supply request for the additional information data, and the supply request for the additional information data includes a supply request for the pay information, an information fee corresponding to the pay information is provided. A billing processing unit that performs billing processing for billing may be provided.

  By doing so, when the display device downloads the pay information as the additional information from the electronic map data supply device, the electronic map data supply device can charge for the pay information.

In any of the electronic map data supply devices described above,
The display device is, for example, a route display device that displays a route to a destination according to a display reference position,
A route storage unit that stores in advance the route to be displayed in the electronic map;
The display request includes the reference position,
The movable object display control unit may specify the display position based on the reference position and the route.

  Here, the “display reference position” corresponds to a so-called display viewpoint and can be arbitrarily set. For example, when the display device is a navigation device, the current location of the display device and the departure location toward the destination correspond to the reference position. The route storage unit may store a route manually designated in advance, or may store a result of route search. In the present invention, the display request from the display device includes the reference position, and the movable object display control unit specifies the display position of the movable object based on the reference position and the route. Therefore, the fixed object and the movable object can be displayed on the route display device at appropriate positions according to the reference position. For example, when the display device is a so-called car navigation device, it can be controlled so that the movable object is displayed without deviating from the field of view as the vehicle moves.

  In addition, as a movable object in this invention, the leading vehicle which performs the route guidance to the destination, a destination display, etc. are mentioned. For example, when the destination is a zoo, the route to the zoo may be guided by a vehicle or an animal. Further, a destination sign may be displayed by setting up a standing signboard at each intersection on the route or installing an ad balloon.

  The present invention can be configured as an electronic map data supply method invention in addition to the above-described electronic map data supply apparatus. Further, the present invention can be realized in various modes such as a computer program that realizes these, a recording medium that records the program, and a data signal that includes the program and is embodied in a carrier wave. In addition, in each aspect, it is possible to apply the various additional elements shown above.

  When the present invention is configured as a computer program or a recording medium that records the program, the entire program for driving the electronic map data supply device may be configured, or only the portion that performs the function of the present invention is configured. It is good also as what to do. The recording medium includes a flexible disk, a CD-ROM, a DVD-ROM, a magneto-optical disk, an IC card, a ROM cartridge, a punch card, a printed matter on which a code such as a barcode is printed, a computer internal storage device (RAM or Various types of computer-readable media such as a memory such as a ROM and an external storage device can be used.

D. Processing on map distribution server:
FIG. 9 is a flowchart showing the flow of electronic map data distribution in the map distribution server 100. First, various setting data such as a departure point, a destination, and necessity of additional information data shown in FIG. 5 are acquired from the navigation device 200 (step S100). Next, the fixed object data is extracted based on the departure place and the destination of the navigation device 200 (step S110). Next, it is determined whether additional information can be displayed and whether additional information is necessary (step S120). If the additional information cannot be displayed, the fixed data is distributed (step S200), and the process ends. In this embodiment, the movable object data is not distributed when there is no request for additional information data. However, the movable object data may be distributed without distributing the additional information data. Good.

  If the additional information can be displayed in step S120, it is determined whether or not the advertisement can be displayed (step S130). If the advertisement can be displayed, a communication fee discount process is executed (step S140). Here, prior to discount processing, user authentication (not shown) is performed. When the advertisement display is impossible, the process proceeds to the next step 150 without executing the discount process.

  Next, it is determined whether or not pay information is necessary (step S150). If pay information is requested, billing processing is executed (step S160). If the above-described authentication process has not yet been performed, the user is authenticated prior to the billing process. If pay information is not requested, the process proceeds to the next step S170 without executing the billing process.

  Next, extraction of movable object data (step S170) and extraction of additional information data (step S180) are performed according to the requested additional information. Then, the display position of the movable object data is determined with reference to the fixed object data (step S190). For example, the display position is determined so that the movable object is not hidden behind the fixed object and is not deviated from the field of view as the vehicle (navigation device 200) moves. Then, the fixed object data, the movable object data, and the additional information data extracted in the above steps are distributed (step S200).

  The electronic map data of this embodiment includes, in addition to fixed object data, movable object data for representing a movable object three-dimensionally and additional information data. In the electronic map displayed three-dimensionally, the fixed object is the one that the viewer of the map pays most attention, and has a great influence on the reality. In contrast, movable objects generally do not affect reality as much as fixed objects. That is, even if a moving object that is different from reality is displayed on the electronic map displayed three-dimensionally, the reality of the map is not impaired. In the present invention, additional information is provided in a state of being integrated with at least a part of the movable object. By doing so, it is possible to visually provide additional information to the viewer of the electronic map data without impairing the reality.

E. Second embodiment:
In the first embodiment, the electronic map data is distributed from the map distribution server 100 to the navigation device 200. In the second embodiment, the navigation device 200A holds electronic map data in advance.

  FIG. 6 is an explanatory diagram showing the configuration of the navigation system 1000A (navigation device 200A) of the second embodiment. Similarly to the navigation device 200 of the first embodiment, the navigation device 200A includes a display panel 210, an operation panel 220, and a control unit 230A.

  The control unit 230A is configured as a microcomputer including a CPU, a RAM, a ROM, etc. In addition to the configuration of the control unit 230 in the first embodiment, an electronic map data storage unit 236, an electronic map data reference unit 237, A route search unit 238. Each of these functional blocks is configured by software.

  The electronic map data storage unit 236 stores electronic map data provided by a recording medium such as a CD-ROM or a DVD-ROM. This electronic map data includes the above-described fixed object data, movable object data, additional data, and path data used for route search. The path data includes so-called link data, node data, and cost data. The electronic map data reference unit 237 refers to the electronic map data stored in the electronic map data storage unit 236. The route search unit 238 searches for a route from the current location or the departure location to the destination using the passage data by a known Dijkstra method.

  Since the navigation device 200A of the second embodiment holds the electronic map data, the viewer can view the electronic map data visually without losing the reality without communicating with the map distribution server 100. Additional information can be provided. However, the navigation system 1000 of the first embodiment is highly useful in that the latest electronic map data can always be used.
