Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to information provision using electronic map data that can be displayed three-dimensionally.
[0002]
[Prior art]
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.
[0003]
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.
[0004]
[Problems to be solved by the invention]
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.
[0005]
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. .
[0006]
[Means for solving the problems and their functions and effects]
  In order to solve at least a part of the above-described problems, the present invention employs the following configuration.
  The data structure of the electronic map data of the present invention is as follows:
  A data structure of electronic map data used to display the electronic map three-dimensionally on 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;
  A virtual movable object that is arranged with the fixed object on the electronic map,Move a position in a three-dimensional virtual space generated based on the electronic map dataMovable object data for three-dimensionally displaying the movable object 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;
  With
  The gist is 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.
[0007]
  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. “Moving objects” are virtual things that are not actually placed in the real world,Move position in 3D virtual spaceMeans things. Examples of movable objects include humans, animals, and travelingInvehicleVoyageAircraft, ship,cloudEtc. are included.
[0008]
In addition to the fixed object data, the electronic map data of the present invention includes movable object data for representing the movable object in three dimensions 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 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.
[0009]
  By doing so, it is possible to visually provide additional information to the viewer of the electronic map data 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.
Further, in the data structure of the present invention, at least one of the movable object data and the additional information data is associated with a display condition that should 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.
[0010]
In the above data structure, additional information that does not directly contribute to the display of the map includes building names, topography (elevation, river length, etc.), weather (weather forecast, temperature, UV information, pollen information, etc.) Various information such as information on
The additional information may be information for advertisement / advertisement.
[0011]
By doing so, it is possible to promote and advertise without losing reality.
[0014]
  The present invention can also be configured as an invention of an electronic map data supply device.
  That is, the electronic map data supply device 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,
  A fixed object data storage unit for storing fixed object data for three-dimensionally displaying the fixed object that exists on the electronic map on the electronic map;
  A virtual movable object that is arranged with the fixed object on the electronic map,Move a position in a three-dimensional virtual space generated based on the electronic map dataA movable object data storage unit for storing movable object data for three-dimensionally displaying the movable object on the electronic map;
  An input unit for inputting a display request for the electronic map including whether or not the movable object can be displayed on the electronic map from the display device;
  A movable object display control unit that specifies whether or not the movable object can be displayed based on the display request, and a position in a three-dimensional virtual space generated based on the electronic map data;
  An output unit that outputs the fixed object data and the movable object data to the display device based on the identified result and the display request;
  It is a summary to provide.
[0015]
Thus, based on the display request from the display device, whether to display the movable object and where to display the movable object on the map is specified, and the fixed object data and the movable object data are displayed on the display device. Can be supplied to. 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.

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.
[0017]
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 an appropriate position 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 moving out of the field of view as the vehicle moves.
[0018]
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.
[0019]
  Moreover, this invention can also be comprised as invention of a map display apparatus. That is,
  The map display device of the present invention comprises:
  A map display device that three-dimensionally displays an electronic map based on electronic map data that can be three-dimensionally displayed,
  The electronic map data is
  Fixed object data for three-dimensionally displaying a fixed object actually existing on the electronic map on the electronic map;
  A virtual movable object that is arranged with the fixed object on the electronic map,Move a position in a three-dimensional virtual space generated based on the electronic map dataMovable object data for three-dimensionally displaying the movable object on the electronic map;
  Additional information data storing additional information to be provided visually to a viewer of the electronic map in a state integrated with at least a part of the movable object,
  The map display device
  A reference unit for referring to the electronic map data;
  A display unit that three-dimensionally displays the electronic map on which the fixed object and the movable object are arranged in a state where the additional information data is integrated with the movable object data based on the referenced electronic map data. When,
  An instruction input unit for inputting a user instruction regarding whether or not to display the additional information;
  The gist of the display is to switch whether or not the additional information can be displayed based on the instruction.
[0020]
By doing so, electronic map data including a fixed object, a movable object, and additional information can be displayed three-dimensionally while maintaining the reality of the map. The electronic map data referred to by the reference unit may be data supplied from the electronic map data supply device of the present invention described above, or a record in which the electronic map data of the present invention described above is recorded. It may be data supplied from a medium.
[0022]
  Further, in the present invention, the display unit can switch whether or not the additional information can be displayed based on a user instruction regarding whether or not the additional information can be displayed.The convenience of the map display device can be improved. The map display device may download electronic map data from a predetermined server via a network such as the Internet. In such a map display device, for example, when the map display device downloads information for advertisement / advertisement as additional information, it is possible to obtain a benefit such as a discount on the communication fee, which is useful to the user. In the case of downloading such information, a mode of providing information such as charging separately may be considered.
[0023]
The present invention can be configured as an invention of a method for supplying electronic map data and a method for displaying an electronic map, in addition to the structure of the electronic map data, the electronic map data supply device, and the map display device described above.

[0048]
FIG. 8 shows a state where the map is seen from a diagonally upper side. As shown in the figure, it is possible to display a movable object as a mark at a branch point (intersection) on the route from the current location to the destination.
[0049]
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.
[0050]
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.
[0051]
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.
[0052]
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).
[0053]
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.
[0054]
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.
[0055]
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.
[0056]
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.
[0057]
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.
[0058]
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.
[0059]
F. Variations:
As mentioned above, although several embodiment of this invention was described, this invention is not limited to such embodiment at all, and implementation in various aspects is possible within the range which does not deviate from the summary. It is. For example, the following modifications are possible.
[0060]
F1. Modification 1:
In the above embodiment, the starting point in the route search is the point detected by the current position detection unit 233 provided in the navigation device 200. However, as with the destination, the user inputs by operating the operation panel 220 or the remote controller 225. It may be.
[0061]
In the above embodiment, the current position detection unit 233 detects the current position based on the radio wave from the artificial satellite received by the GPS antenna. However, a method using a DGPS (differential GPS) or a mobile phone The current position may be detected by a method using radio waves from a wireless base station such as PHS or a method using or using a gyro sensor.
[0062]
F2. Modification 2:
In the above embodiment, the navigation device 200 can select whether or not to display additional information. However, this selection may not be possible. In this case, the navigation device 200 is always provided with movable object data and additional information data.
[0063]
F3. Modification 3:
In the first embodiment, the map distribution server 100 distributes the fixed object data, the movable object data, and the additional information data. However, the present invention is not limited to this. In general, according to the present invention, electronic map data used in a map display device only needs to include fixed object data, movable object data, and additional information data. Therefore, for example, the navigation device 200 may hold the movable object data in advance, and the map distribution server 100 may distribute the fixed object data and the additional information data.
[0064]
F4. Modification 4:
Although the case where the present invention is applied to a so-called car navigation device mounted on a vehicle has been described in the above embodiment, the present invention is not limited to this. For example, the present invention can be applied to a personal computer capable of displaying an electronic map, a portable information terminal, a portable navigation device, and a mobile phone.
