Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information guide using a building shape map for displaying information on a building and surrounding information by displaying the shape of the building in a coordinate sequence by changing the color and other display modes. Related to the device.

[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.

A conventional vehicle navigation system sets a guide route to a destination and displays a road map and a set guide route on a display, and a remaining distance and a name of an intersection to be turned based on the guide route. There are those that provide information such as turning right and left, and that teach the features so that the guidance route during traveling can be confirmed, and those that provide not only display but also voice guidance.

When a destination is an unfamiliar area, for example, it is common practice to first check the location (destination), and then check a route from the current position to the destination. It 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 departure place and the destination are determined by this point input, a route search process is performed for the first time from the road information data around the departure place and the destination and between them, and an optimal guide route is set from a plurality of guide routes. .

[0005] The applicant of the present invention has made various proposals for such a point input method such as a departure place and a destination. For example, registration points to be registered, such as a departure place and a destination, are classified into genres such as sightseeing, parking lots, restaurants, and the like, and are separately coded according to regions such as prefectures and cities, and the codes are input. It is. In this case, in addition to directly inputting a code number, a method of displaying a menu and sequentially selecting and inputting from the menu has been proposed. In addition, it has node data, defines a road network by linking this node data, and inputs points by coordinate values of east longitude, north latitude,
A method of inputting locations by telephone number has also been proposed.

Conventionally, when setting a point such as a current position or a destination, or when it is desired to see where a destination is located on a map, the user inputs a place name such as a prefecture name or a city name as described above. To display a desired map by sequentially switching from a wide-area map to a detailed map using the scale of the map, or to display a map centered on the registered point by inputting a telephone number. Was.

[0007]

However, among the conventional methods of inputting points such as a departure point and a destination which are indispensable as initial operations in a vehicle navigation apparatus, a code input method uses a special code number. Since each point is defined, a code book is required, and the point input cannot be performed unless the code book is referred to one by one. In addition, the code book is enormous because all the codes are mounted, and must be carried.

In the menu system, a desired point cannot be input on one screen, and a desired point cannot be input unless a plurality of screens are sequentially switched and a predetermined item is selected on each screen. That is, since the display device used in the vehicle navigation device is mounted in a relatively easy-to-see space near the driver's seat, a compact device is adopted, and the amount of information that can be displayed at one time is small. Therefore, there is a problem that the screens are finely classified and the number of menu screens increases, and the input operation takes time and labor.

The method of inputting coordinates is also troublesome in that a point cannot be input without a coordinate table, and the coordinate value of the point to be input must be retrieved from the coordinate table.

[0010] On the other hand, in the method of inputting a telephone number, a telephone number that is used every day can be input as it is, so that there is no trouble in inputting. However, unless the telephone number is memorized or checked accurately. No.

However, in any of the above methods, when a desired point is to be input, what kind of building, facility, etc. are present at that point and its surroundings, and what shape they are. Can not be checked or confirmed. Also, for example, in an urban area where buildings are densely populated, many tenants are occupying one building,
When trying to check the building in which such a tenant is occupied, it is not possible to search for or confirm the building in which the corresponding tenant is occupied without information on the tenant occupying each building. Conventionally, there is nothing that can search and confirm such information.

[0012]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide an easy-to-understand display of the shape and characteristics of a building for guiding information on the building. . Therefore, the present invention, as an information guide device by a building shape map, stores map data having information on the shape of each building, facility and other various structures and information belonging to the building, and belongs to the building. It is characterized in that the display mode is determined based on the information, the shape of the building is displayed according to the display mode, and information relating to the building and surrounding information is searched and guided.

It is a figure showing the example of the display screen of a 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 includes the map data storage device 1
From 00, the data of the building shape map in the display range is read, and for example, the color of the shape is determined as a display mode from the type and height of the building and other detailed information (scale of the configuration, etc.), and for each name based on the coordinate sequence. The building shape and its name are drawn and displayed as a building shape map, and when a building is selected on the displayed building shape map, information and peripheral information belonging to the building are searched and guidance output. Or, on the contrary, a shape map centering on a building is displayed from information belonging to the building. The shape display processing unit 200a includes, for example, a type, a height,
It performs a process of drawing and displaying a shape map of a building in a so-called display mode having different colors, densities, and their patterns based on the scale of the configuration. The name display processing unit 200b

The search guidance processing unit 200c includes various information related to the building, such as a list of names of companies, offices, stores, and the like occupying the building, telephone numbers, and similar information existing around the building (peripheral information). Or search for a building, or search for a building based on a telephone number or name and guide it on a shape map. 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. The input instruction device 400 is for inputting an output range (area) of a building shape map, an area of a building on the map, information guidance on the building, searching for peripheral information, and the like, and inputting an instruction. A touch panel, a joystick, a pointing device such as a mouse, and a remote controller combined with the 300 display screens are used.

In the central processing unit 200, as shown in FIG. 2, for example, when a building shape map is selected while a road map of the selected scale 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, information on the structure, such as the store or office in the building if it is a building, the specific name of the tenant, the type of business, the business content, the telephone number, etc. (Step S5). The shape of a building is a planar shape for general houses and buildings and other buildings, and the 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 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 towns and public facilities are displayed in descending order of priority by setting the town name, public facilities, and names with a lot of in-building information.

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. 3A, data of each of N buildings is stored next to the number N of data of the building. You. 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 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 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.

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 out the coordinate series stored as shape data in the building shape map data and connecting them with lines, and the name is displayed on it. 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). This display mode is the color of the shape to be displayed, its density, their pattern, etc. as described above, and is determined based on the type, height, and scale of the configuration. 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).

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. For things like roads and parks, there is no height or detailed information.

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 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. 5 shows an example of the process. First, names are stored in the order of the number m of names in the detailed information from the data of the display range (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.

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 the 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 using a building shape map, and FIG. 9 is a diagram showing an example of an information display screen. FIG. 10 is a diagram showing an example of an information guide screen based on a building shape map, FIG. 11 is a diagram showing an example of a list display screen for searching for surrounding information of a building, and FIG. 12 is a diagram showing an example of a genre search screen. is there.

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.
A cross-shaped cursor is displayed on a circle as shown in (1), and the building is selected by inputting a building selection instruction from the input instruction means. Therefore, in the search / guidance process, as shown in FIG. 7, the system waits for the selection of a building (step S41). When the building is selected, as shown in FIG. Then, options of each mode of the peripheral information search are displayed (step S42). When the present invention is incorporated in a vehicle navigation device to be described later,
It is used for setting a point for a route search, and a description thereof is omitted here. Hereinafter, the description will be limited to each mode of information and peripheral information search.

Then, it is checked whether the selection key is information or peripheral information retrieval (step S43). If the information column is selected as shown in FIG. 8, the number of names of detailed information of the corresponding building data is determined. And each name is read to create a list of names in alphabetical order, and the information is displayed as shown in FIG. 9 (step S4).
4). Then, when one of the name fields therein, for example, Iue Co., Ltd. is selected as shown in FIG.
45) The address (address), the selected name, telephone number, classification, and the like are read from the building data, and the name, telephone number and address of Iue Co., Ltd. are displayed as shown in FIG. 10 (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, when the field for searching for peripheral information is selected, first, as shown in FIG. 11, "fiber / woven fabric production and sales", "fiber A genre list (a list of classifications) such as "Dyeing and design of textiles",... 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), and the searched predetermined distance. The names within are sorted in ascending order of distance, and as shown in FIG. 12, a list of the genre name, the number of cases, each searched name and the distance from the search point is displayed (step S50). When one of the name fields is selected (step S51), the address (address), the selected name, telephone number, classification, etc. are read from the building data and displayed as in the case of FIG. 10 (step S51). 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. In the case of an instruction other than the selection of the classification column in step S48 and an instruction other than the selection of the name column 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 organizations, 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.

[0037]

As is apparent from the above description, according to the present invention, when displaying the data of the building shape map stored in the coordinate sequence, the color and the like are determined by the type and height of the building. Is determined, the characteristics of the shape and the characteristics of the building itself, such as the type and height, can be immediately recognized even if the map is a complicated and dense area. In addition, even if the buildings have the same size, differences in their scales can be identified by determining the display mode based on the height, the number of residents, and the like.

For example, when a map is displayed, the shape is displayed, and the color of the shape having specific information is changed to change the color of the shape. When recognizing a point, the identification becomes easy. Further, by changing the color of the shape in accordance with the size of the shape, the size relationship between the buildings can be easily determined, and the feature of the corresponding map area can be recognized. When the color is changed according to the type of shape, the distribution of the shape in the display area can be recognized, and the visibility can be improved when the facility is selected according to the purpose.
