DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building for displaying the name of a building on a building shape map on which the shape of the building is displayed by a coordinate sequence, and searching for and guiding information belonging to the building and surrounding information. The present invention relates to an information guide device having object information.

[0002]

2. Description of the Related Art When a map is displayed and various kinds of guidance are performed on the map, the name of a place, the name of a building, a facility, or another building is displayed along with the map as the minimum necessary information. When such a place name or the name of a building is to be displayed and displayed, it is necessary to prepare display coordinates and a display area separately from map data as data for name display in order to display in advance. Conventionally, name data is stored together with map data.

[0003] A vehicular navigation device performs a route search from a current position or a designated departure point to a destination based on a point input such as a destination, and provides route guidance based on the searched route. A map is used for point input and route guidance. Therefore, when setting a point such as the current position and destination, or when you want to see where the destination is located on the map, the prefecture name,
A wide-area map is displayed by inputting a place name such as a city name, and a desired map is displayed by sequentially switching from a wide-area map to a detailed map using a map scale, or a registration point is input by inputting a telephone number. The map centered on the was displayed.

In the address input method, for example, when an attempt is made to input a point "3-16-3 Ueno, Taito-ku, Tokyo", "Tokyo" is first selected according to the hierarchical data structure in the prefecture. , And then select "Taito-ku" as the city and "3-chome" as the representative address.
The map of "Ueno 3-chome near Taito-ku, Tokyo" is read from the memory and displayed on the screen. Then, the user inputs a point by searching for and instructing a point "3-16-3 Ueno, Taito-ku, Tokyo" on the map.

[0005]

However, in the conventional method of preparing data for map display and data for name display, respectively, the amount of data is large, and further, in a device for displaying a map by changing the scale, Since it is necessary to store the data for displaying the name for each display scale, there is a problem that the data amount is remarkably increased and a memory having a large storage capacity is required.

When displaying the names of districts and buildings on a map, it is necessary to prevent the names from overlapping so as not to impair the visibility of the map. On the other hand, for example, in an urban area where buildings are densely populated, many tenants are occupying one building, and when an attempt is made to check the building in which such a tenant is occupying, information on the tenants occupying each building Without it, you will not be able to find or confirm the building in which the tenant is located. Conventionally, there is no search or guidance for detailed information belonging to such a building or the like.

In the case of the address input method as described above, if a menu is prepared so that all addresses can be input even if the number of the address is known, the hierarchical level of the menu is increased. There is a problem that operation becomes complicated. Also, if the corresponding point cannot be accurately indicated on the map even when the map around the desired point is displayed, the desired point cannot be input, and even if the desired point is input, the point may not be accurate. . Similarly, if you search for a map using a telephone number near a desired point using the telephone number input method, if the corresponding exact position on the map is not known,
I can't enter that point.

FIG. 5 is a diagram for explaining a display process of a building shape map, and FIG. 6 is a diagram showing an example of a display screen of a building shape map.

In FIG. 1, a map data storage device 100
Draws the shapes of buildings (general houses, office buildings, condominiums, fire departments, department stores, hospitals, stations, etc.), facilities (towers, parks, amusement parks, playgrounds, etc.), bridges, roads and various other so-called buildings. It stores data of a building shape map to be displayed, and may further store data of a road map, data of a house map, and the like. The data of the building shape map includes a coordinate sequence of a plurality of coordinate values for drawing and displaying the shape of the building, a name of the building, an address (address), various information belonging to the building, for example, a type,
It has information such as height, composition (resident), and its telephone number.

The central processing unit 200 reads the data of the building shape map in the display range from the map data storage device 100 and, for example, displays the building type and height and other detailed information (such as the scale of the configuration) as a display mode. A shape display processing unit 200a that determines the color of the shape and draws and displays the shape of the building and its name as a building shape map for each name based on the coordinate sequence.
When a building is selected on the displayed building shape map, the information and peripheral information belonging to the building are searched and output as guidance, or conversely, from the information belonging to the building. A search guidance processing unit 200c for displaying a shape map centering on a building is provided.

The shape display processing unit 200a performs a process of drawing and displaying a shape map of a building in a so-called display mode having different colors, densities, and patterns thereof based on, for example, the type, height, and scale of the configuration. Is what you do. Name display processing unit 2
00b performs processing of drawing and displaying the names of the main shape objects on the shape map displayed by the shape display processing unit 200a. Information such as names displayed in this case may be restricted according to the vehicle speed, that is, as the vehicle speed increases. For that purpose, the vehicle speed is set to a predetermined speed (for example, 0, 20, 40, 60, 80, 100 km).

In addition, as a content of editing in this case, a predetermined distance may be calculated, and information searched according to the distance may be edited. For example, the information is rearranged and displayed in a list in ascending order of distance, or a condition of the number of pieces of information to be displayed is determined, and only a predetermined number of pieces of information are edited and displayed. Further, in the case of a navigation device for a vehicle, information may be edited and displayed with priority given to the vehicle in the traveling direction, based on the traveling direction of the vehicle.

The output device 300 is a display for displaying a building shape map, guidance information output by the central processing unit 200, a printer for printing out, and the like. Input device 40
Numeral 0 is for inputting the output range (area) of the building shape map, the area of the building on the map, information guidance on the building, selection of the search of the peripheral information, etc., and input of instructions. A touch panel combined with a screen, a pointing device such as a joystick or a mouse, and a remote controller are used.

In the central processing unit 200, as shown in FIG. 2, for example, when a building shape map is selected in a state where a selected scale road map is displayed (step S1).
First, a shape map display process is executed (step S2),
A display process of a building name is executed on the shape map (step S3). After that, the information belonging to the building, for example, in the case of a building, information such as the specific name, business type, business content, telephone number, etc. A search guidance process based on a building shape map is executed for information on genres and addresses within the range (step S5). The shape of a building is its planar shape if it is a general house, building, or other building, and its planar topography if it is a park or road. Therefore, in the case of a building having a large number of residents, there is information on the residents of the building, and even if it is the shape of one building, it has a lot of information. In the display processing of the building and the display processing of the building name in step S3, for a building or a public facility with a lot of such information, the shape is displayed in a display mode that is easily recognizable and different from ordinary houses, and priority is given. The name is displayed, and if the name overlaps, the name is not displayed. Furthermore, the names of the towns and the public facilities are displayed in the order of the town name, the public facilities, and the name with the largest information in the building by setting a higher priority.

The data structure of the building shape map stored in the map data storage device 100 is such that, for example, as shown in FIG. You. The data of each building includes information on the name, address (address), type, shape, height, and details of the building. The name is the building name if it is a building,
If it is a private house, it is the name of the resident, if it is a facility, it is the name of the facility, if it is a road, it is the type of street or street name such as "Chuo Dori" or "National Route 1". It is the address of the building. The shape of the building is represented by the number of coordinates n representing the shape.
And its coordinate values (x ₀ , y ₀ ), (x ₁ , y ₁ ),.
..., (x _n-1 , y _n-1 ), and the type is a general house,
Information on condominiums, office buildings, public facilities, roads, parks, etc. The height is information on the floor number and the height (m).
For example, in the case of a tenant building, the details are information on each resident. For the number m of names and each tenant, the name, telephone number, room number, classification (type of business such as restaurant, convenience store,..., Business content). Information. Therefore, as shown in FIG. 3B, by sequentially reading out coordinate values as information relating to the shape of the building, connecting and drawing with a line, and displaying it, for example, the planar shape of a building or a house or the topography of a park can be output. it can.

Next, the display of the building shape map will be described. As described above, the building shape map is drawn and displayed by sequentially reading a coordinate sequence stored as shape data in the data of the building shape map, connecting the lines, and displaying the name thereon. In the shape display process, as shown in FIG. 4A, the data of the building shape map in the display range is retrieved and read from the map data storage device 100 (step S11), and the display form of the building shape to be displayed is displayed. Is determined (step S12). The display mode is the color of the shape to be displayed, its density, their pattern, and the like as described above, and is determined based on the type, height, and configuration scale. For example, by type, public facilities, stations, theaters, museums, amusement parks, towers, condominiums, buildings other than ordinary houses, etc. can be distinguished. In public facilities, public institutions such as government offices, police stations, public halls and parks And public facilities such as sports grounds, and even buildings other than ordinary houses can be distinguished by height (number of floors), number of tenants, and the like. After the display mode is determined in this way, a building shape map is displayed (step S13), and the inside of the shape is displayed in the determined display mode (step S14).

The display mode in step S12 is obtained by registering a display mode determination table as shown in FIG. 4B, for example, by referring to the data of the building shape map to be displayed and this display mode determination table. , Can be determined. In FIG. 4B, when the building to be displayed is a public facility, the color is a, and when there is detailed information instead of the public facility, it is divided into shades of b color according to the scale. Other than the above, when the height is equal to or more than a predetermined value, an example in which the display mode of colors, their densities, their patterns, and the like is set according to the type, height, and configuration scale, such as a c-color net pattern, etc. It is. Therefore, when this display mode determination table is used, the following processing is performed in step S12. As shown in FIG. 4C, the data of each building shape map is referred to as a display mode determination table (step S2).
1) First, it is checked whether or not the type is a public facility (step S22). If the type is a public facility, the display mode is determined to be a color (step S23). If it is not a public facility,
Next, it is checked whether or not there is detailed information (step S24).
If there is, whether the number of names in it is equal to or more than α (step S25),
The display mode of the color (step S27), which does not reach α, is determined to be a light b color (step S26). Even if there is no detailed information, the height of the building is further checked (step S28). If the height is equal to or more than a certain height, the display mode is determined to be a c-color net pattern (step S29). In this example, priority is given to whether or not the facility is a public facility, then detailed information, that is, the scale of the structure of the building is prioritized, and finally, the display mode is determined by the height. In the case of a building that is not a building, such as a road or a park, there is no detailed information as information relating to the height or the building.

The names displayed on the buildings vary in length, and not all names can be displayed depending on the size of the screen and the display range. Therefore, as in the case of determining the display mode, for example, a priority order based on the type and a priority order depending on the degree of the detailed information are provided and displayed in a range where they do not overlap. FIG. 5 shows an example of this processing. First, the names are stored in the order of the number m of names in the detailed information from the data in the display range (step S3).
1). Thereafter, the display range of the names on the map is calculated for all the names in descending order of the number m of names (step S32) (step S33), and the display ranges of the names that do not overlap with the display ranges of the names already displayed (step S34). Is displayed on the map (step S35). Then, the display range is stored (step S36), and the process returns to step S32 to repeat the same processing.

Here, the display range of the name is determined by distributing the character from the center of the building to both sides according to the number of characters from the vertical and horizontal size of the character, the character interval, and the coordinates of the upper left and lower right positions of the character string. It is memorized. If the display range is not overlapped, judging only from the vertical and horizontal size of the character and the character spacing, adjacent names are displayed at a short interval on the whole surface, making it difficult to see the map. If the distances are longer than the above, processing may be performed to determine that the display ranges do not overlap. As a method in this case, for example, the character size α
This can be realized by setting the display range to β times on the left and right, and setting a predetermined number of characters on the upper, lower, left and right as the allowable interval.

As described above, in the data of the building shape map of the present invention, the center coordinates and the coordinates of the display range when displaying the name can be determined by calculation from the coordinate sequence of the shapes. Therefore, even when the map data storage device is configured to store not only the building shape map but also data of a map other than the building shape map and switch between the map and the building shape map on the display screen, the map data storage device may be used. Another map such as a map or a house map is displayed, and the name of the data of the building shape map can be displayed in a display range calculated from the coordinate sequence. In this case, the processing of displaying the map and the processing of displaying the name can be executed without being conscious of the others at all, and the display of the map and the display name can be eliminated by making the respective display coordinates coincide. The combination of such processing makes it possible to share the shape coordinate sequence and name in the data of the building shape map with other maps such as a road map and a house map as data for name display, greatly increasing the data amount. Can be reduced.

FIG. 6 shows a display example of a building shape map.
The names of parks, public facilities, and streets are also displayed as building names. Furthermore, what is represented by several patterns in each building has a different display mode, and in the case of color display, it can be distinguished by color, density, and a combination of those patterns. Therefore, the display mode is changed according to data type information, height information, the number of detailed names, and the like. For example, in public facilities such as schools, city halls, and stations, parks, and tenant buildings, buildings with large names are displayed differently from normal display modes, so that landmarks and features in the area displayed as a map can be determined. It can be easier.

Next, search / guidance using a building shape map will be described. 7 is a diagram for explaining a search guidance process using a building shape map, FIG. 8 is a diagram showing an example of a screen at the time of a building selection operation based on a building shape map, and FIG. 9 is a list display screen for a peripheral address search.

When the building shape map displayed as described above is used, not only the building but also information on its surroundings can be searched based on the data described with reference to FIG. Guidance of information in the object can be provided. For example, in a building shape map, FIG.
And a cross-shaped cursor is displayed on the circle as shown in FIG.
The building is selected by inputting a building selection instruction from the input instruction means. Therefore, search and
In the guidance process, as shown in FIG. 7, the system waits for the selection of a building (step S41). When the building is selected, the destination, the passing point, the memory, the information, and the peripheral information are searched as shown in FIG. Then, options of each mode such as a peripheral address search are displayed (step S42). Destinations and passing points,
The memory is used for setting a point for a route search when the present invention is incorporated in a vehicle navigation device to be described later, and a description thereof is omitted here. Hereinafter, information, peripheral information search, and peripheral address search will be described. Each mode will be described.

Then, it is checked whether the selection key is information, peripheral information retrieval, or peripheral address retrieval (step S43). When the information column is selected as shown in FIG. The number of names and the names of the detailed information are read to create a list of names in alphabetical order, and the information is displayed as shown in FIG. 11 (step S44). And 1 of the name column in it
For example, when Iue Co., Ltd. is selected as shown in FIG. 11 (step S45), the address (address), the selected name, telephone number, classification and the like are read from the building data and read as shown in FIG. Then, the name, telephone number and address of Aiue Co., Ltd. are displayed (step S46). In addition,
The return, destination, pass point, and memory displayed on this screen are operation keys, and when such other operation keys are selected, respective processes are executed by interruption. Also,
Also in the case of an instruction other than the selection of the name column, other processing corresponding to the instruction is similarly executed by interruption.

In the step S43, when the field of the peripheral address search is selected as shown in FIG. 8, first, the distance of each address is obtained (step S53), and as shown in FIG. The (address) is sorted in the order of the address or in the order of the Japanese syllabary, and the address of the point (the selected building) on the immediately preceding map is displayed together with the number in a manner that is easy to understand and different from other display modes (step S54). . If another desired address field is designated by scrolling the address field (step S55), the address (address), the selected name, the telephone number, etc. are read from the building data as in the case of FIG. Are displayed (step S56). here,
When the return key is input, a surrounding building shape map centering on this building is displayed.

In the case where the field for searching for peripheral information is selected in step S43, first, as shown in FIG. "Dyeing and designing textiles and fabrics", ...
A genre list (a list of categories) such as... Is displayed (step S47). Then, when a certain classification column is selected (step S48), the selected classification is searched from the detailed information of the data, and the distance to the selected building is obtained (step S49). The names within are sorted in ascending order of the distance, and a list of the genre name, the number of the genres, the names searched and the distance from the search point is displayed as shown in FIG. 14 (step S50). When one of the name fields is selected (step S51), FIG.
As in the case of No. 2, the address (address), the selected name, the telephone number, the classification, and the like are read from the building data and displayed (step S52). Here, when the return key is input, a surrounding building shape map centered on this building is displayed. Of course, the building shape map may be displayed using another key (not shown), or the map may be switched to another map such as a road map. In the case of an instruction other than the selection of the classification field in step S48 and the instruction other than the selection of the name field in step S51, other processing corresponding to the instruction is interrupted and executed.

As described above, when the map information guide device of the present invention is used, a map of the point is called by, for example, inputting an address, a telephone number, or the like, and then calling a map of that point, for example, within a range of 500 m. You can list the addresses in the. Then, by selecting a specific address from the address list, a map of the point can be displayed. This function can be used to find a desired address point from a list of neighboring addresses after calling up a map with a simple operation of a town name or telephone number without complicated entry of what number and what number Useful for

Further, when a list is displayed, for example, if an address is entered up to 3-16 Ueno, Taito-ku, Tokyo, the central processing unit determines that the user wants to search in the vicinity of No. 16, Based on the search result of the address search, as shown in FIG. 9, control is performed to display a list from 3-16 Ueno, Taito-ku, Tokyo, so that the user can easily select a desired point.

When inputting a request for information search, search conditions may be manually set. For example, when searching for a bookstore, by setting the address and the predetermined number as conditions, such as "Toyota City, Aichi" and a predetermined number of 20, the result of the search by the control means (central processing unit) It is also possible to edit and output so as to satisfy the above conditions.

Further, from the building shape map, information on companies, offices, stores, various organizations, etc. occupying the building,
Furthermore, it is possible to look up the telephone numbers and the like of the individual companies, and to search for and list various companies, stores, and various institutions within a certain range from the building, and list the building. You can find out. Conversely, by inputting a telephone number and a name, and searching for the name and the telephone number from the name of the map data shown in FIG. 3, the name of the detailed information and the telephone number, the building centering on the building is obtained. A shape map can be easily displayed. Therefore, if you know the name and classification information and the general area, but you do not know the building, you can search for the building, for example, the occupied building, and also check the tenant occupying a certain building. Can be provided, and if this is used for setting a point of a vehicle navigation device, there is an advantage that the point setting in an urban area becomes easy. Furthermore, in the case where a road is targeted as one of the buildings, if the presence / absence of a parking meter can be provided as information on the road, it is also possible to provide information on parking when driving by car.

It should be noted that the present invention is not limited to the above embodiment, and various modifications are possible. For example, in the above-described embodiment, the name of a building is described, but the name may include a town name and other district names. Although it has been described that the processing is performed for all the names, it is set in advance that information on the priority to be displayed on the map and the presence or absence of the display is set or added to the name, and the processing is performed so that the name is displayed based on the information. Alternatively, processing may be performed on objects having the number of names equal to or more than a predetermined number and names equal to or more than a predetermined height. In addition, although the xy coordinate sequence is data representing the shape of the building, the coordinate value (z) in the height direction is also included as three-dimensional coordinate data. For example, when a three-dimensional shape such as a diagram viewed obliquely from above or a perspective is used, a coordinate sequence of xyz may be used. Furthermore, the present invention can provide more friendly point guidance by incorporating it into a vehicular navigation device. It goes without saying that it is also possible to carry out. Needless to say, the present invention can be similarly applied to a general road map, a city map, a house map, and the like.

[0048]

As is apparent from the above description, according to the present invention, a coordinate sequence and a name of a shape are stored as data of a building shape map, and a display range of the name is determined from the coordinate sequence to determine a map. Since it is displayed on the upper side, the name of the data of the building shape map can be displayed in the display range determined from the coordinate sequence even when displaying a road map, a house map, or the like. Therefore, even when a plurality of types of maps are switched and displayed, the name of the data of the building shape map can be shared, and the amount of data to be stored can be reduced.

In particular, in an apparatus configured to be able to change the display scale of a map in accordance with the application in order to display the map, in order to display the name of the building on the map,
Since the displayable area and the number of names to be displayed are different based on the scale, it is necessary to store data for name display for each display scale, and the data capacity increases. Further, when storing additional information such as the shape of a building and detailed information as data, the data amount of the additional information is further increased, and it is required to reduce the data capacity. Therefore, adopting the configuration of the present invention in an apparatus having a plurality of map scales can achieve a very large effect in reducing the data capacity.

Further, when the ratio of the data of the building shape map to the display area is large, the display contents are overlapped,
Although the visibility of the map and the name may be reduced, according to the present invention, the display position of the name and the display area are calculated and the display is controlled so that the display areas do not overlap, so that the visibility of the display screen is reduced. Can be prevented. Therefore, when confirming the location from the display map, the visibility of the screen can be improved by the map and the guidance display.

Further, by judging the priority order based on information such as the type, height, structure (resident) of the building, and displaying the name, public facilities are prioritized by omitting ordinary houses from the type information. , Priority on tall buildings from height information,
Buildings with a large number of residents can be processed from the detailed information on the configuration (residents) so that a name with a high information value can be selected and displayed.

Further, by searching for an address within a predetermined distance from a point on the map, listing and displaying the address, the address can be easily searched. Furthermore, by changing the address of a point on the map to another display mode, it becomes easy to recognize the reference address, and the searched addresses are sorted and listed in the order of addresses commonly used as addresses, such as street addresses. By doing so, it is possible to easily search for a desired address from the listed addresses.
