Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building shape map display device and a storage medium for searching a building from a telephone number and displaying a building shape map centering on the building.

[0002]

2. Description of the Related Art A vehicular navigation apparatus searches for a route from a current position or a designated departure point to a destination based on a point input such as a destination, and displays a screen or voice based on the searched guidance route. By providing the route guidance by using the information, the information along the guide route of the driver is provided when the vehicle travels on an unfamiliar road. Therefore, in the vehicular navigation device, a search function for searching a route from the current position to the destination by inputting the destination, a current position detecting function for detecting the current position and the direction of the own vehicle, It has a guidance function and the like that matches the current position with the route and guides the route to the destination according to the searched route.

By the way, in the case where the destination is an unfamiliar area, for example, it is common to first check the place (destination) and then the route from the current position to the destination. Is. Vehicle navigation devices are no exception, and to provide route guidance, it is necessary to search for and set the guidance route. To search for and set the guidance route, the departure point, destination, transit point, etc. It is necessary to enter a point. When the starting point and the destination are determined by this point input, the route searching process is performed for the first time from the road data around the starting point and the destination and between them, and the guide route is set.

Conventionally, when setting a point such as a current position and a destination, or when it is desired to see where the destination is on the map, a wide area map is created by inputting a place name such as a prefecture name or a city name. A wide area map is displayed and a detailed map is sequentially switched using a map scale to display a desired map, or a telephone number is input to display a map centered on the registered point.

[0005]

However, in the vehicular navigation device, not only when setting a point such as a destination or a waypoint, there are cases where it is desired to confirm where the point is. In such a case, , In the conventional method, the prefecture name, city name, code, menu, coordinates, etc. are selected and input to display the map, and at this time, the wide area map is specified to the detailed map by operating multiple keys. There is a problem that the operation for reading out the detailed map is complicated and not easy, and it takes time. Also, in the method of inputting a telephone number and displaying a map centered on that point, a desired detailed map can be displayed only by inputting a telephone number, but further information cannot be obtained.

That is, even if a detailed map can be displayed by inputting a telephone number, if there is a plurality of detailed information at that point, such as a complex building, it is not possible to confirm whether it is one of them. However, it is not possible to check or confirm what kind of features buildings, facilities, etc. are at a desired point and its surroundings, and what shape they are. For example, in an urban area where buildings are densely populated, many tenants are occupying one building, and when trying to find a building in which such a tenant is located, there is no information on the tenants occupying each building. And, it is not possible to find or confirm the building in which the relevant tenant resides.
Conventionally, there is no map information whose main purpose is to provide rough information, such as the above-mentioned complex building or a multipurpose facility composed of various residents, for searching and confirming information.

[0007]

The output device 200 is a display for displaying a menu screen by the central processing unit 400, a telephone number input screen, a building shape map, a guide information output screen, a printer for printing out, or the like.

The information storage device 300 stores telephone number data 300a having coordinate values corresponding to each telephone number, information on the shape of each building or facility and various structures, and information on the building including the telephone number. Map data with 3
00b is stored. Phone number data 300a
Has the coordinates of the representative point and the coordinates of the point of each subscriber number for each area / city code. The map data 300b is for buildings (general houses, office buildings, apartments, fire stations,
Department store, hospitals, stations, etc.), facilities (towers, parks, amusement parks, playgrounds, etc.), bridges, roads and other various so-called building shapes. It may also have map data, house map data, 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 400 obtains coordinates from the telephone number data 300a by inputting a telephone number, determines a certain range, retrieves the telephone number from the map data 300b within the range, and finds the building of that telephone number. The processing for displaying the building shape map as the center is performed, and the map data 300 based on the building shape map also displayed.
A process for searching and guiding the information held by b is also performed. The telephone number search unit 400a of the central processing unit 400 is
The telephone number data 300a is searched from the input telephone number to obtain the coordinates. The map data search unit 400b determines a fixed range around the coordinates searched by the telephone number search unit 400a and searches for a telephone number from the map data 300b. The building shape map display processing unit 300c draws and displays a building shape map in a so-called display mode having different colors, densities, their patterns, and the like based on, for example, the type, height, and configuration scale. The processing for drawing and displaying the names of the main shaped objects is performed above. The search guidance processing unit 300d includes various types of information about a building, such as a list of names of companies, offices, stores, etc. that move in the building, telephone numbers, and similar information existing around the building (peripheral information). Is used to search for and guide, or a building is searched based on its name and the like to be guided on a shape map.

The specific structure of the telephone number data 300a is, for example, as shown in FIG. 2, for the number n of the area / city code, the area / city code, representative point east longitude / north latitude, registered telephone number address / size. With each data of, the registered telephone number 300b can be searched from the area / city code. The registered telephone number has the subscriber number and the east longitude / north latitude data for the registered telephone number m.

The concrete data structure of the building shape map stored in the information storage device 300 is, for example, as shown in FIG. Remembered. The data of each building is composed of information such as the name, address (address), type, building shape, height, and details of the building. The name is the name of the building if it is a building, the name of the resident if it is a private house, the name of the facility if it is a facility, the type of road such as "Chuo-dori" or "National Route 1" if it is a road. The street name, and the address (address) 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 information such as ordinary houses, condominiums, office buildings, public facilities, roads, and parks. The height is information on the number of floors 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.

FIG. 4 is a diagram for explaining the process of displaying a building shape map by a telephone number according to the present invention, FIG. 5 is a diagram for explaining the process of displaying a building shape map, and FIG. 6 is a building name. FIG. 7 is a diagram for explaining the display processing of FIG. 7, and FIG. 7 is a diagram showing an example of a display screen of the building shape map.

Next, the process of displaying the building shape map by telephone number will be described. When the telephone number is input on the telephone number input screen, as shown in FIG. 4, first, coordinates are searched from the telephone number (step S1), and a range centered on the coordinates is set (step S2). Here, the telephone number data shown in FIG. 2 is searched to find the coordinates of the point east longitude / north latitude of the registered telephone number, or if there is no registered telephone number, the coordinates of the representative point east longitude / north latitude are searched and the A range for searching the data of the building shape map shown in FIG. 3 is set. In this case, if the coordinates of the registered eastern longitude / north latitude of the registered telephone number are obtained, it is possible to set a narrow search range. This is a setting for a wide search range. Next, a telephone number is searched within the set range (step S3), and it is checked whether or not the telephone number is found (step S4). Here, the telephone number is searched from the data of the building shape map shown in FIG. 3. However, since the coordinates are searched in step S1 and the search range centered on it is set in step S2, the building is directly searched. The amount of information to be searched can be narrowed down far more than the case where a telephone number is searched from the data of the shape map. Especially,
In the building shape map data shown in FIG. 3, various information is stored and a telephone number is searched from detailed information that has a large amount of information. Therefore, if a telephone number is directly searched from the building shape map data, the search is required. Although the time becomes very long, the search time can be shortened and the information stored in the detailed information can be used for the spot search by adopting the present invention. If the telephone number is found, the center position of the building shape in which the telephone number is registered is set to the map center coordinates (step S5). If the telephone number is not found, the coordinates searched by the telephone number are set to the map center coordinates. (Step S6), and the shape map and name of the building are displayed (step S7). As described above, the coordinates are searched from the telephone number by the telephone number data, the search range is set around the coordinates, and the data of the building shape map is searched, so that the useless search is performed with the data of the building shape map. This makes it possible to efficiently search for a telephone number and increase the search speed. Furthermore, since a point can be searched using the detailed information of a building, a point search with high search accuracy can be performed.

As described above, the building shape map is drawn and displayed by sequentially reading out the coordinate sequence stored as shape data in the building shape map data and connecting the lines with a line, and displaying the name on it. Is displayed. Of these, the shape display processing is performed by the map data storage device 10 as shown in FIG.
Data of the building shape map in the display range from 0 is retrieved and read (step S11), and the display mode of the building shape to be displayed is determined (step S12). This display mode means the color of the shape to be displayed as described above, its density,
These are the patterns, etc., and are decided based on the type, height, and scale of the composition. 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, the building shape map is displayed (step S13), and the inside of the shape is displayed in the determined display mode (step S14).

As for the display mode in step S12, if a display mode determination table as shown in FIG. 5B is registered, the data of the building shape map to be displayed and this display mode determination table are referred to. , Can be determined. In FIG. 5 (B), when the building to be displayed is a public facility, the color is a, and when there is detailed information instead of a public facility, it is divided into shades of b according to its scale. Other than the above, if the height is equal to or more than a predetermined value, an example in which the display mode of colors, their densities, those patterns, etc. is set in correspondence with the type, height, and scale of the configuration, such as a c-color mesh pattern Is. Therefore, when this display mode determination table is used, the following processing is performed in step S12. As shown in FIG. 5C, the data of each building shape map is referred to the 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. For things like roads and parks, there is no height or detailed information.

The names displayed on the building have different lengths, and it is not possible to display all the names depending on the size of the screen and the display range. Therefore, as described above, for example, the priority order according to the type and the priority order depending on the amount of the detailed information are provided and displayed within the range where they do not overlap. FIG. 6 shows an example of the processing. First, names are stored in the range of data to be displayed in descending order of the number m of names in the detailed information (step S31). 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 S3).
6) Return to step S32 and repeat the same processing.
Here, the display range of the name is determined by sorting 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 spacing, and is stored by the coordinates of the upper left and lower right positions of the character string. . 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 upper and lower sides of the character string are α times the character size, and the left and right sides are β
This can be realized by setting the double as the display range or setting a predetermined number of characters in the upper, lower, left, and right directions as the allowable interval.

The shape of a building is a planar shape for general houses and buildings and other buildings, and a planar terrain for parks and roads. 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 a single building, it has a lot of information. , And in the display processing of the building name, for such buildings and public facilities with a lot of information, the shape is displayed in an easily recognizable display mode different from ordinary houses, and the name is displayed with priority, and the name is displayed. Is displayed, the name is not displayed. further,
By setting the priority of the names of the towns and the public facilities to be higher, the names of the towns, the public facilities, and the names with the largest information in the building are displayed in this order.

FIG. 7 shows a display example of the building shape map.
In addition to displaying the cross-shaped cursor KL in the center of the map, the building shape at the center is highlighted to display the names of major buildings such as public facilities, parks, street names, etc. It was done. 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 the building shape map will be described. FIG. 8 is a diagram for explaining a search guidance process based on a building shape map, FIG. 9 is a diagram illustrating an example of a screen at the time of a building selection operation using a building shape map, and FIG. 10 is a diagram illustrating an example of an information display screen. FIG. 11 is a view showing an example of an information guide screen based on a building shape map, FIG. 12 is a view showing an example of a list display screen for searching for surrounding information of a building, and FIG. 13 is a view showing an example of a genre search screen. is there.

From the information belonging to the building, for example, in the case of a building, information such as the specific name and industry of the tenant, such as the store or office occupying the building, business content, telephone number, etc., is the building shape. It is possible to search and guide on the map. That is, by using the building shape map displayed as described above, it is possible to search not only for the building but also for the surrounding information based on the data described in FIG. You can guide the information inside. For example, in a building shape map, a cursor in the shape of a cross is displayed in the center as shown in FIG. 9, and by inputting a building selection instruction from the input device,
The structure is selected. Therefore, in the search / guidance process, as shown in FIG. 8, the selection of the building is waited (step S41), and if the building is selected, the destination, the passing point, the memory, the information as shown in FIG. ,
The options for each mode of peripheral information search are displayed (step S42). The destination, the passing point, and the memory are used for setting a point for a route search when the present invention is incorporated in a vehicle navigation device described later, and a description thereof is omitted here. Description will be made only for each mode of search.

Then, it is checked whether the selection key is information or peripheral information search (step S43). When the information column is selected as shown in FIG. 9, the number of names of detailed information of the corresponding building data is selected. And each name are read to create a list of names in the order of Japanese syllabary, and the information is displayed as shown in FIG. 10 (step S4).
4). Then, when one of the name columns in the list, for example, AIUE CORPORATION is selected as shown in FIG. 10 (step S45), the address (address) from the building data, the selected name, telephone number, classification Etc. are read and the name, telephone number and address of AIUE CORPORATION are displayed as shown in FIG. 11 (step S46). The return, destination, passing point, and memory displayed on this screen are operation keys, and when such other operation keys are selected, the respective processes are executed by interruption. Also, in the case of an instruction other than the selection of the name column, similarly, other processing corresponding to the instruction is interrupted and executed.

In step S43, if the field for searching peripheral information is selected, first, as shown in FIG. 12, in order to specify the search range of peripheral information, "manufacture and sale of textiles / fabric", "fiber" Display a genre list (classification list) such as "dying and design of textiles" ... (Step S47). Then, when a category (genre) column is selected (step S48), the selected category is searched from the detailed information of the data, and the distance to the selected building is obtained (step S49), and the search is performed. The names within the specified predetermined distance are sorted in ascending order of distance, and as shown in FIG. 13, a list of the genre name, the number of cases, each searched name and the distance from the search point is displayed (step S5).
0). When one of the name columns is selected (step S5
1) As in the case of FIG. 11, the address (address), the selected name, telephone number, classification, etc. are read from the building data and displayed (step S52). Here, when the return key is input, a building shape map around 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. Step S48
In step S51, if the instruction is other than the selection of the name field in step S51, another process corresponding to the instruction is interrupted.

When the information guide device for building shape maps according to the present invention is used, information on companies, offices, stores, various institutions, etc., which reside in the building can be obtained from the building shape map, as well as the individual information. It is possible to check the telephone number of the company, etc., and to search and list various companies, stores, various institutions, etc. within a certain range from the building to check the building. 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.

The output values of the various sensors are constantly corrected. Here, the route guidance is configured so that the driver can select either the screen display or the voice output.

The program required for navigation may be stored in the ROM of the central processing unit 4 in advance, or may be stored in the information storage device (storage medium) 3. When the program is stored in the information storage device 3, for example, when the program is read from the information storage device 3 and stored in the flash memory, a new program is updated by replacing the information storage device 3, It becomes possible to execute. The program read from the information storage device 3 is temporarily stored in the RA
It can also be stored in M to handle the navigation function.

The telephone number data file stored in the information storage device 3 of the vehicle navigation system is shown in FIG.
As shown in (1), it consists of telephone number data, registered telephone number, mark data, and spot data. The telephone number data points the registered telephone number and mark data, respectively, and the mark data points the spot data. Phone number data is
Area / city code, representative point east longitude / north latitude, map display scale,
Registered phone number address, size, landmark data address,
With size data, it is possible to search registered telephone numbers from area / city code and spot data by genre name. The registered telephone number has data of a subscriber number, a subscriber name, a point east longitude / north latitude, a map display scale, and a registered telephone number. The landmark data has genre name, location data address, and size data, and the location data has location data name and its reading, east longitude / north latitude, map display scale, and registered location number. . As shown in FIG. 16, the registration point number data includes information on whether the registration place type is a general registration point or a town page, and each type internal number data. As shown in FIG. 17, the address data has a lower left east longitude coordinate and a north latitude data address meshed at a predetermined distance, and a lower left north latitude coordinate and address name data for each point destination.
Address names can be searched from the coordinates of the north latitude.

Therefore, when the telephone number is input, the area / local area code of the telephone number data is searched, and if there is a subscriber number that matches the registered telephone number, the subscriber name is obtained and the subscriber is subscribed. If there is no person number, the genre name is displayed from the mark data, and the spot data name of the genre name designated from the genre name is displayed. At this time, the spot data names are displayed in the order of the Japanese syllabary so as to be easily searched based on the reading of the spot data, and the head search is performed by the scroll buttons.
When the subscriber name and the location data name are displayed, the address name is acquired from the coordinates of the east longitude and the north latitude based on the address data, and displayed together. In this manner, when the subscriber number is searched, or when the subscriber number is not searched and the points registered by genre are selected, the respective points are centered on the east longitude / north latitude and the map display scale, and the surrounding area is set around the point. Display a map of. However, if the desired point is not registered as a genre-specific point, the representative point of the telephone number data is east longitude / north latitude, and the center is set to the representative point preset by the area / city area code on the map display scale. A map of the surrounding area is displayed, and a desired point is input in coordinates while scrolling the map. The building shape map of the present invention can be adopted as the map displayed here.

Next, the operation will be described. When the program of the route guidance system is started by the CPU 51 of the central processing unit 4, first, as shown in FIG.
The current position is detected by and the peripheral map around the current position is displayed, and the name of the current position is displayed (step S1). Next, telephone number, address, facility name,
Set the destination using the registration point etc. (step S2),
A route search from the current position to the destination is performed (step S
3). When the route is determined, the route guidance / display is repeated until the vehicle arrives at the destination while tracking the current position by the current position detecting device 2 (step S4). If a detour setting is input before arriving at the destination, a search area is set, a re-search is performed in the search area, and route guidance is repeated until the vehicle arrives at the destination.

In the vehicle navigation device as in the present invention, the telephone number data, the building shape map data, and the road data are stored and held, and various points can be obtained by inputting a point by the telephone number. It can be used for various uses. For example, by entering a phone number,
By accessing the data shown in FIG. 3 and performing the display processing shown in FIGS. 4 to 6, the building shape map shown in FIG. 7 is displayed. Therefore, if the location is first confirmed (designated or selected), the location setting, information, and peripheral information search for the building can be selected using the screen shown in FIG. By setting and registering the destination, the passing point, and the memory point, setting and registration of the point, it is possible to perform a route search using the coordinates of the point and perform route guidance by a road map. Figure 1 for information and peripheral information search
Since it is possible to confirm and search information as described with reference to FIGS. 0 to 13, it is possible to further confirm detailed information of the point and peripheral information.

The present invention is not limited to the above embodiment, but various modifications can be made. For example, in the above embodiment, after storing the telephone number data having coordinate values corresponding to each telephone number and obtaining the coordinates from the telephone number,
Although the telephone number of the map data is searched within a certain range around the coordinates, the telephone number of the map data may be directly searched. Further, the following may be performed. The central processing unit sets an area existing in the input telephone number from the road map information stored in the information storage means, based on the telephone number data input by the input means. Next, it is determined whether or not there is building shape map information in this set area, and if there is building shape map information, a search is performed from the building shape map information stored in the information storage means. To do.
If there is no building shape map information, the representative point is searched. In this way, by controlling the telephone number search by the central processing unit, the search data can be shared between the road map information and the building shape map information. Since the search from the map information can be limited to a small area, the time required for the search can be significantly reduced.

In the shape display, colors and other display modes are determined based on information such as height, number of residents, type, and classification.
The display mode may be individually set in advance, or the display mode may be added to the head of the coordinate sequence, for example. Further, although the xy coordinate string is used as the data representing the shape of the building, it also has the coordinate value (z) in the height direction as three-dimensional coordinate data, and in the case of a plan view, the xy coordinate string is shown. It is also possible to use only xyz and use a xyz coordinate sequence in the case of a three-dimensional shape diagram such as a perspective view or a perspective view. 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.
