According to the invention described in claim 4, the designated building is three-dimensionally displayed, and the entire floor selected in the building is highlighted in the three-dimensionally displayed building and is included in the selected floor. Since the name list of the facilities to be created is created and the name list is displayed, the facilities included in the selected floor can be easily confirmed.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a diagram showing an embodiment of an information guide device using a building shape map according to the present invention, and FIG. 2 is a diagram for explaining display guidance processing of a shape map by the information guide device using a building shape map according to the present invention. FIG. 3 is a diagram showing an example of the data structure of a building shape map.

  In FIG. 1, the storage device 100 includes buildings (general houses, office buildings, condominiums, fire departments, department stores, hospitals, stations, etc.), facilities (towers, parks, amusement parks, playgrounds, etc.), bridges, roads, etc. It stores building shape map data 100a for drawing and displaying various so-called building shapes, and display form change data 100b for changing the display form of the destination point for easy recognition. Road map data, building shape map data, and the like may be stored. The building shape map data 100a includes a coordinate string composed of a plurality of coordinate values for drawing and displaying the shape of the building, the name, address (address) of the building, and various information belonging to the building, for example, type , Height, configuration (residents), and information such as its phone number. The display form change data 100b is displayed according to the type, area, or the like of whether the set building is a condominium, a private house, or a facility when a point is set in a building shape map described later. Data (for example, data such as different marks according to the type and area), data that can also display the height direction and floor of the building, and the like.

  The central processing unit 200 reads the data of the building shape map in the display range from the storage device 100, and based on the coordinate sequence, the shape of the building based on the type and height of the building and other detailed information (such as the scale of the configuration). When a map is drawn and displayed and a building is selected on the displayed building shape map, the display form change data is read from the storage device 100 and the display form of the building is changed and highlighted. Three-dimensional display is performed, information belonging to the building and surrounding information are searched and guided and output, and conversely, a shape map centered on the building is displayed from the information belonging to the building. For example, the shape display processing unit 200a draws a building shape map on the basis of the type, height, and configuration scale of the building, and draws and displays the name of the main shape object on the shape map. Is what you do. The display form change display processing unit 200b selectively displays different marks according to the type, area, etc. of the building, or performs a three-dimensional display process to draw and display the marks. The search guidance processing unit 200c can provide various information related to the building, for example, a list of names of companies, offices, stores, etc. that move into the building, telephone numbers, and similar information existing in the vicinity of the building (peripheral information ), And a building is searched from a telephone number and a name and guided on a shape map. The output device 300 is a building shape map by the central processing unit 200, a display for displaying guidance information output, a printer for printing out, or the like. The input instructing device 400 is used to input an output range (region) of a building shape map, a building area on the map, information guidance on the building, selection of search for surrounding information, and instructions, for example, an output device. A touch panel combined with 300 display screens, a pointing device such as a joystick and a mouse, and a remote controller are used.

  In the central processing unit 200, for example, when a building shape map is selected in a state where a road map of a selected scale is displayed as shown in FIG. 2 (step S1), first, a display process of the shape map is performed. This is executed (step S2), and a building name display process is executed on the shape map (step S3). After that, if the information belongs to a building, for example, if it is a building, the shape of the building with respect to the resident's specific name, type of business, business details, telephone number, etc. A map search guidance process is executed (step S5). The shape of the building is a flat shape if it is a general house, building, or other building, and is a flat shape if it is a park or road.

As for the data structure of the building shape map stored in the map data storage device 100, for example, as shown in FIG. The data of each building includes information on the name, address (address), type, shape, height, and details of the building. The name is the name of a building, the resident name of a private house, the name of a facility of a facility, the name of a facility such as “Chuo-dori” or “National Highway 1”. It is a street name, and the address (address) is the address of the building. The shape of the building is the coordinate number n representing the shape and its coordinate values (x ₀ , y ₀ ), (x ₁ , y ₁ ), ..., (x _n-1 , y _n-1 ), The type is information on general houses, apartments, office buildings, public facilities, roads, parks, and the like. The height is information on the floor number and the height (m). For example, in the case of a building for rent, the details are information on each resident. For the number of names and each resident, the name, telephone number, room number, number of occupancy floors, classification (restaurant, convenience store, etc.) Business type, business content). Therefore, as shown in FIG. 3B, coordinate values are sequentially read out as information relating to the shape of the building, and connected and drawn with lines to display, for example, the planar shape of a building or a house or the topography of a park can be output. it can.

  Next, the change process of the display format of the destination point will be described with reference to FIG. The display format of the destination point is changed with respect to the set destination point in the building shape map. 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 them with lines as described above. For example, FIG. A building shape is displayed on the road map as shown in FIG. 5B.

  This building shape map data is not necessarily prepared for every region. Therefore, when the destination point is input by coordinates or a telephone number, the input x and y coordinates are searched, and it is searched whether or not the coordinates are within a certain range of the building shape map (steps S11 to S13). If the building shape map is within a certain range, the building shape map is displayed (S14), and if it is not within the building shape map, a conventional road map is displayed (S15). Then, the cursor is moved on the screen, the position of the point where the cursor stops is detected, and the point is set (S16 to S19). When the building shape map is displayed, the building shape corresponding to the input (x, y) coordinates is searched, the type and area of the searched building shape are determined (S20 to S21), and displayed. The form is determined (S22). When a conventional road map is displayed, the display form is determined after setting the points.

  For example, a display form when a building shape map is displayed will be described with reference to FIGS. 6 and 7 taking mark display as an example.

FIG. 6 shows an example of the mark selection condition table. For example, the mark No. a to d, and mark numbers “0”, “1”, “2”, “3” to “10”, and 11 or more names such as personal names and telephone numbers. a to d, and mark Nos. with respect to areas (m ² ) 0 to 150, 151 to 250, 251 to 600, 601 to 1200, 1201 or more. a to e are made to correspond.

  Mark No. For example, marks a to e are registered in a mark table as shown in FIG. 7, and are registered to mean a private house, a two-storied house, an apartment, a condominium, and a villa, respectively.

Therefore, the type of the searched building is determined. For example, if the number of floors is 3 to 5, the mark No. is referred to the mark selection condition table. As a result, the mark indicating the apartment is called up and displayed with reference to the mark table of FIG. If the number of searched building names is 11 or more, the mark No. is selected from the mark selection condition table. d is known, and a mark indicating the apartment is displayed with reference to the mark table. In addition, if the area of the searched building is 1201 m ² or more, the mark no. e is known and the mark of the villa is displayed with reference to the mark table.

  In addition, by displaying only the set buildings, and deleting the shape of other buildings (buildings, houses, factories, etc.) from the shape map display, roads, rivers, tracks, etc. Only the buildings and destination points related to the land are displayed, the destination points are highlighted and displayed, and the roads, rivers, tracks, etc. are displayed, so the positional relationship between the destination points can be clearly understood.

  In addition, when the position of the cursor is detected and the point is set, the corresponding building is searched, and the three-dimensional shape mark selected by the central processing unit from the plane section of the building is displayed. By performing display processing as if a building was built at that point, the corresponding building can be more easily recognized.

  Not only the mark display but also the corresponding building may be easily recognized by three-dimensional display as shown as A in FIG.

  Next, search / guidance using a building shape map will be described. FIG. 9 is a diagram for explaining search guidance processing using a building shape map, FIG. 10 is a diagram illustrating an example of a screen during a building selection operation using a building shape map, and FIG. 11 is a diagram illustrating an example of an information display screen. FIG. 12 is a diagram showing an example of an information guidance screen by a building shape map, FIG. 13 is a diagram showing an example of a list display screen for peripheral information search of a building, and FIG. 14 is a diagram showing an example of a genre search screen. is there.

  By using the building shape map displayed as described above, it is possible to search not only for the building based on the data described in FIG. Information can be provided. For example, in a building shape map, a crossed-out cursor is displayed at the center as shown in FIG. 10, and the building is selected by inputting a building selection instruction from the input instruction means. . Therefore, in the search / guidance process, the system waits for this building selection as shown in FIG. 9 (step S41), and if there is a building selection, the destination, passing point, memory, information as shown in FIG. Then, options for each mode of the peripheral information search are displayed (step S42). The destination, passing point, and memory are used for setting a point for route search when the present invention is incorporated in a vehicle navigation device to be described later, and will not be described here. Only the search modes will be described.

  Therefore, it is checked whether the selection key is information or peripheral information search (step S43), and when the information column is selected as shown in FIG. 10, the number of names of detailed information and the names of the corresponding building data. Are created in alphabetical order and their information is displayed as shown in FIG. 11 (step S44). Then, when one of the name fields in the list, for example, Aiue Corporation is selected as shown in FIG. 11 (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. 12 (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. In the case of an instruction other than the selection of the name column, other processing corresponding to the instruction is similarly interrupted and executed.

  When the peripheral information search field is selected in step S43, first, as shown in FIG. 13, in order to specify the search range of the peripheral information, “manufacture and sale of fiber / textile”, “fiber / textile A genre list (classification list) such as “dyeing, design”,... Is displayed (step S47). When a certain category field is selected (step S48), the selected category is searched from the detailed information of the data, the distance from the selected building is obtained (step S49), and the predetermined distance searched. Names within are sorted in ascending order of distance, and as shown in FIG. 14, a list of the genre names and the number of cases, and each searched name and 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 FIG. Step S52). Here, when a return key is inputted, a building shape map around the building is displayed. Of course, the building shape map may be displayed using another key (not shown) or 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 an instruction other than the selection of the name field in step S51, other processing corresponding to the instruction is interrupted and executed.

  Next, an example of stereoscopic display of a building will be described.

  FIG. 15 is a diagram for explaining a search / guidance processing flow for three-dimensionally displaying the shape of the building selected by the input instruction means.

  As in the case of FIG. 9, it waits for the building selection from the input instruction means (step 61). If there is a building selection, as shown in FIG. 10, the destination, passing point, memory, information Then, the selection of each mode of the peripheral information search is displayed (step 62). Next, it is checked whether the selection key is information or peripheral search (step 63). If peripheral search is selected, the processing jumps to the processing of step 47 in FIG. 9 and the same processing is performed.

  Next, a description will be given with reference to FIG. 16 showing a case where the selected building has height information and there are a plurality of tenants.

  FIG. 16 (a) shows a screen in which information is selected, and options are displayed on the building shape map. By selecting information, the number of names of detailed information of the corresponding building data and each name are read. A list of names is created and divided into screens and displayed as shown in FIG. 16B (step 64). Next, with the list displayed as it is, as shown in FIG. 16C, the building shape is three-dimensionally displayed (step 65), and then the building floor at the cursor position in the list is highlighted ( Step 66). At this time, by selecting the list item with the cursor, the floor of the selected item is highlighted as shown in FIG. Next, when the name column is selected, as shown in FIG. 16 (f), detailed information such as the address of the building data, the selected name, the telephone number, the classification, the genre of the store, the type of business, etc. is read and displayed. (Step 67, Step 68). Further, when the return key is operated in the state of FIG. 16F, the screen returns to the screen of FIG. Further, the gradation display of the building floor can be moved by the up / down operation of the cursor, and the tenant or private house included in the floor currently displayed in the gradation is displayed in the list.

  Further, a case where there is one tenant will be described with reference to FIG. 17. When information is selected in FIG. 17A, the number of names of detailed information of building data and each name are read to create a list of names. A process of splitting and displaying the screen is performed. In this case, since there is one tenant, the name, telephone number, address, etc. are displayed as shown in FIG. Next, with the list displayed as it is, as shown in FIG. 17C, the building shape is three-dimensionally displayed, and the second floor (tenant floor) of the building is highlighted. In addition, about the three-dimensional display method of a building, the method shown by Unexamined-Japanese-Patent No. 9-62179 is used, for example.

  If there is no height information, the 3D display is naturally not performed, but the other processes are the same.

  FIG. 18 is a diagram for explaining a search / guidance processing flow for three-dimensionally displaying the shape of a building selected by inputting a telephone number or name.

  When a destination point is input by telephone number or name (50 sounds), the corresponding point data is searched (steps 71 and 72). If there is building shape data in this search, the building shape is three-dimensionally displayed (step 73, step 74). Next, as described with reference to FIG. 16, after highlighting the building floor at the cursor position in the list, the detailed information of the input point is displayed.

  In the above example, the list of names is divided and displayed on the screen. However, the list may be displayed in a separate window on the map display without dividing the screen. In the above example, the floor of the selected item is highlighted by selecting the item in the detailed information list with the cursor. Conversely, the floor of the three-dimensional building is selected with the cursor. The tenants included in the selected floor may be displayed in a list and selected from the list. As a highlighting method, bold line display, filled display, color-coded display, blinking display, or the like may be employed as appropriate. Further, the floor may be highlighted with a three-dimensional display, and the number of floors highlighted with characters may be displayed.

  Next, an example of a three-dimensional display process will be described with reference to FIGS.

  FIG. 19 is a diagram showing an example of a three-dimensional display processing flow of a building, FIG. 20 is a building shape map, FIG. 21 is a diagram showing an example of three-dimensional display of a building with a constant floor height, and FIG. FIG. 23 is a diagram illustrating an example in which the height of the building is made constant and the floor height is variable, and FIG. 23 is a diagram illustrating the display method of FIG.

  In FIG. 19, the height of the building is searched from the building shape map data (step 81), and it is determined whether or not the searched height can be displayed on the screen at a constant display scale (step 82). If display is possible within the screen, the height per floor is fixed and the building is three-dimensionalized (step 83), and then the plan map is tilted to three-dimensionally display the building (step 85 and step 86). For example, in the plan map of the city as shown in FIG. 20, the selected building is displayed in three dimensions by tilting the plan map with the height per floor fixed as shown in FIG. FIG. 21A shows a case of one floor, FIG. 21B shows a case of two floors, and the corresponding floor is highlighted.

In addition, in step 82 of FIG. 19, if it cannot be expressed in the screen, the height of the building is fixed at the maximum value, the height per floor is changed (step 84), and the plane map is similarly tilted. Display in 3D. For example, FIG. 22 (a) shows a case of 20 stories and FIG. 22 (b) shows a story of 40 stories, and the corresponding floor (FIG. 22 (a) is the 8th floor and FIG. 22 (b) is the 19th floor) is emphasized. It is displayed. In this display method, as shown in FIG. 23, when the height h of the building is greater than or equal to a predetermined value, the height h is matched with the height l ₁ of the setting frame indicated by the broken line, and the display width of the building is displaying to fit within the width l _2. In this case, the image is displayed at a display scale that fits within the setting frame.

  In addition, the method of displaying a building three-dimensionally is not limited to the above example, but may be a bird's-eye view viewed from above or a display that allows the building to be viewed horizontally from the horizontal direction. . The display scale may be a constant scale, but if displayed at a constant scale, it may be difficult to see depending on the size of the building, so the display scale may be changed so that it is easy to see according to the height of the building. Good. Further, only the building portion may be enlarged and displayed, or the building may be enlarged and displayed in a separate frame while leaving the building shape map.

  By using the information guide device by the building shape map of the present invention, information on companies, offices, stores, various institutions, etc. that move into the building from the building shape map, and further, A telephone number or the like can be checked, and various companies, stores, various institutions, etc. within a certain range from the building can be searched and listed to check the building. On the other hand, by entering a telephone number or name and searching for the name or telephone number from the map data name, detailed information name or telephone number shown in FIG. It is easy to display a shape map. 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 occupying building, and the tenant occupying a certain building. Since this can be used for setting the point of the vehicle navigation device, there is a merit that it becomes easy to set the point in an urban area. Furthermore, when a road is targeted as one of the buildings, information on parking when acting by car can be provided if the presence or absence of a parking meter can be provided as information on the road. Below, the structural example of the navigation apparatus for vehicles which can utilize the information guidance apparatus by the building shape map which concerns on this invention is demonstrated.
