DETAILED DESCRIPTION OF THE INVENTION
Next, based on an accompanying drawing, the present invention is explained in detail about an embodiment and an example of the present invention.
[0018]
FIG. 1 is a diagram showing an outline of an image map portable distribution system as an embodiment of the present invention, and FIG. 2 is a diagram showing a configuration of an image map distribution server in the system of FIG. As shown in FIG. 1, the image map mobile distribution system includes an image map distribution server 100. The user can access the image map distribution server 100 through the communication line 1 such as the Internet using the mobile phone 10 possessed by the user and receive a guide service to a desired destination. Further, the image map distribution server 100 can be accessed by a terminal such as a personal computer having a browser function and can receive a guide service.
[0019]
As shown in FIG. 2, the image map distribution server 100 mainly includes an input / output device 110, a database 120 that stores various map image data, photographic image data, and the like as described later, and various types as described later. A memory 130 for storing files and a central processing unit (CPU) 140 for controlling the overall operation are provided.
[0020]
First, map image data, photographic image data, and the like recorded in the database 120 will be described.
[0021]
Map image data includes wide-area map image data with attribute data such as building names at major points on a relatively wide-area map identified by prefecture name, city name, ward name, etc. Map image data added with attribute data such as building names at major points on a relatively narrow area map identified by each area name obtained by dividing a wide area map is made into a database.
[0022]
As photographic image data, oblique aerial photograph image data obtained by adding the attribute data such as the building name on the oblique aerial photograph obtained by photographing the area corresponding to each of the above-mentioned wide-area maps, and the aforementioned narrow-area maps. Similarly, the narrow area aerial photograph image data to which the attribute data such as the building name is added on the oblique aerial photograph of the corresponding area is adjusted to form a database.
[0023]
Furthermore, as another photographic image data, the above-mentioned terrestrial photographic image data photographed at the main location on the wide area map and the narrow area map are also adjusted to form a database.
[0024]
Next, a specific example of the above-described method for acquiring each image data will be described. FIG. 4 shows an example of a wide area map including the Nishi Shinjuku area, the Higashi Shinjuku area, and the Minami Shinjuku area in Shinjuku-ku, Tokyo. As indicated by the numbers in parentheses, for example, the Nishi Shinjuku area is divided into four narrow areas, the Higashi Shinjuku area is divided into five narrow areas, and the South Shinjuku area is divided into two narrow areas. The FIG. 5 shows an example of a narrow area map corresponding to the narrow area section (4) of the Nishi Shinjuku area in the wide area map of FIG. By adjusting the map image data by adding attribute data such as building names to each of such a wide area map and narrow area map, attaching the area name etc., and recording it in the database, Prepare map image data over the entire area to be provided with the guide service.
[0025]
At the same time, the oblique aerial photo image data corresponding to the wide area map including the Nishi Shinjuku area, the Higashi Shinjuku area, and the Minami Shinjuku area, and the oblique aerial photo image data corresponding to the Nishi Shinjuku area, the Higashi Shinjuku area, the Minami Shinjuku area, etc. By adjusting and recording in the database, oblique aerial photographic image data is prepared over the entire area where the guide service is to be provided.
[0026]
In addition, as shown by various arrows at various points on the map of FIG. 5, various ground photographs at each point are taken, and the ground photograph image data is adjusted and recorded in the database. By going, the ground photograph image data over the entire area where the guide service is to be provided is prepared.
[0027]
Such a method for acquiring ground photograph image data will be described in more detail with reference to FIGS. This ground photo image data acquisition method can also be referred to as an alley search ground photo acquisition method. In principle, the shooting points are intersections where roads cross, main points on narrow streets, and the like. This point will be further described with reference to FIG. In FIG. 6, reference numerals 1 and 2 indicate shooting points, reference signs A, B, C, and D indicate shooting directions, and arrows indicate zoom stages. As the camera, for example, a CCD camera with zoom or a normal camera with zoom is used, and a zoom photograph of at least three stages is taken from one photographing point. As for the shooting direction, shooting is performed in both directions.
[0028]
Referring to FIG. 6, at the shooting point 1, shooting is performed in the A direction and the B direction, three zoom photographs are taken in the A direction, and four zoom photographs are taken in the B direction. 2, the A direction, the B direction, the C direction, and the D direction are taken. In the A direction, a three-stage zoom photograph is taken, in the B direction, a four-stage zoom photograph is taken, and in the C direction. This shows that three-stage zoom photographs are taken, and four-stage zoom pictures are taken in the D direction. The important thing about taking this ground photograph is to take the photograph from the viewpoint of the pedestrian in several cuts from the entrance to the exit of the lining, for example, in order to provide the user with a guide service to the destination as intuitive as possible Then, it is to prepare a ground photograph in which a signboard or the like on which the name of each store is written is copied as much as possible.
[0029]
The ground photograph image data acquired and adjusted in this way may be organized as a ground photograph database index table as exemplified in FIG. According to such an index table, as will be understood from the description to be described later, the following can be performed as a method for selecting a ground photograph (alley back photograph).
(1) When a point on the screen is specified (point search)
Switch to zoom-in image display from the same point (screen size is the same)
(2) When you want to move to a place that is not visible on the screen (street search)
Move shooting point 1 → 2 → 3
(3) When you want to see the street at once (entire street monitor)
By automatic setting, the image is switched in the order of 1 → zoom 1, zoom 2, zoom 3 → 2 → zoom 1.
When a smooth moving image is to be created by batch processing, a digitally enlarged image is created during the change from one image to the next zoom image, an interpolated image is created, and the number of frames is added.
[0030]
Next, a method for giving relevance to various image data recorded in the database 120 as described above will be described. It is important to associate the mutual links of the map image data, the oblique aerial image data, and the ground image data while maintaining the consistency of the position. For this reason, as shown in FIG. Map image-diagonal aerial photo image mutual link file 131, oblique aerial photo image-ground photo image mutual link file 132, and map image-ground photo image mutual link file 133 for enabling mutual link between the image data and the oblique aerial photo image data Is created and stored in the memory 130. By using these reciprocal link files, by clicking a desired point on the image displayed on the display, it becomes possible to replace and display the images displayed on the display in a mutually related state. .
[0031]
Further, a difference in scale of the target point, which is a disadvantage of the oblique aerial photograph, is calculated in advance, and a diagonal aerial photograph address scale file 134 is created to add a scrollable function at the same scale, and the memory 130 It is good to memorize. The oblique aerial photo address scale file 134 associates the X and Y image addresses with the scale value so that the oblique aerial photograph image can be scrolled at the same scale.
[0032]
Furthermore, a ground photo route network file 135 is created and stored in the memory 130 for associating the ground photo with the route to the destination (the route through the road, street, street, road, etc.). It is good to keep. In accordance with this, a selection image file 136 corresponding to the route X and Y addresses and a scale file 137 corresponding to the address in the ground photograph may be created and stored in the memory 130. By using these files, roads in road photographs and the like can be used. As with oblique aerial photos, signs are also taken for images taken for each alley unit, such as those that were taken in consideration of the prospects so that the signs of all side road buildings were imprinted according to the degree of bending of It is also possible to select an optimal photograph that can be confirmed, and to automatically select and display a scale that allows character confirmation.
[0033]
Next, a method for enabling various image map distribution modes as described later will be described. The above-described ground map image data, oblique aerial photo image data, and the like are added with attribute data such as region names and building names. These attribute data can be organized and associated with each image data. Then, it is possible to efficiently and sequentially deliver images according to the purpose desired by the user. As one method for doing this, it is conceivable to create a building attribute classification file 138 and store it in the memory 130 as shown in FIG. 8 to 11 show examples of such building attribute classification files.
[0034]
To explain the role of such a building attribute classification file 138, when a user wants to go to “KDD Building” in Shinjuku-ku, Tokyo, the user can display an index displayed on his / her display, for example, FIG. You can click on the part corresponding to “Communication / Information Service” in the file. As a result, a list of building names related to communication / information services is displayed on the display. When the user clicks “KDD building in Shinjuku-ku, Tokyo” from the display, for example, in Shinjuku-ku, Tokyo Since a map image (index map or screen) of the area is displayed, it is possible to enter a more detailed destination search mode by searching for the building name “KDD building” pasted on the map image. it can.
[0035]
Of course, the present invention is not limited to such divisions, and various other division methods are possible. For example, it is possible to prepare a division file for each region, not for each application. In this case, the user clicks “Shinjuku Ward” from among the area names such as “Chiyoda Ward”, “Shibuya Ward”, “Ota Ward”, and “Shinjuku Ward” displayed on the display. An image (index map or screen) can be viewed.
[0036]
Next, an operation method by the user when using the image map distribution system having the above-described configuration will be described for each usage.
[0037]
First, in the point search image map distribution mode (point mode), the entire image is first displayed, and then a partially enlarged image of the destination is obtained and distributed. As this application, a meeting mode, a destination introduction mode, etc. can be considered.
[0038]
Next, in the destination route search distribution mode (line mode), an image map including the destination point and neighboring stations is created and distributed. In the distribution image, a name such as a remarkable high building can be transmitted as necessary. That is, in this mode, the user specifies the destination (building name, government office name, etc.), and searches for the nearest station image displayed to include the nearest station and destination. You can receive image distribution.
[0039]
Next, there is a distribution map for each purpose (surface mode), and this mode is used to obtain a determination of where to go when the destination is not clear. The distribution by purpose (hospital, convenience store, department store, etc.) is divided in advance in the attribute database as described above, so this distribution (position) is displayed on the image map and distributed. This mode is a point search mode that cannot be pinpointed. After the determination, the mode is the point search mode, and after the determination, the mode is shifted to the point search image map distribution mode. In this mode, the user selects a building use in the entire image to be displayed, and a point is pasted and distributed.
[0040]
In order to further organize and simplify the distribution modes as described above, the processing procedure of each distribution mode is shown in the block diagrams of FIGS. FIG. 12 shows a processing procedure in the point confirmation mode (point), FIG. 13 shows a processing procedure in the route confirmation mode (line), and FIG. 14 shows a processing procedure in the destination building search mode (plane). 15 shows the processing procedure of the alley search mode. This mode is a mode for finding micro building information that is not on the map by using an advertising signboard or the like. Data is utilized.
[0041]
Next, with reference to FIGS. 16 to 29 in particular, each use mode by the user as described above will be described more specifically, particularly with a focus on display screens of personal computers and mobile phones used by the user. To do.
[0042]
First, FIG. 16 is a diagram for exemplifying a case where the map image displayed on the display shifts to the corresponding oblique aerial photograph image. When the map image shown on the left side of Fig. 16 is displayed on the display of my terminal, I would like to see a diagonal aerial photo image centered between the Tokyo Metropolitan Government Building 1 and the Keio Plaza Hotel South Building. In such a case, the user only has to double-click the part with a + sign on the screen. Accordingly, as shown in the right side of FIG. 16, the oblique link aerial photograph image corresponding to the above-described map image centered on the Keio Plaza Hotel South Building is displayed on the display by the position interlocking function as described above. It becomes like this. Therefore, the user can grasp the situation of the area more intuitively by looking at the oblique aerial photograph image.
[0043]
FIG. 17 is a diagram for exemplarily explaining a case where the oblique aerial photograph image displayed on the display shifts to a corresponding map image. When the oblique aerial photograph image shown on the right side of FIG. 17 is displayed on the display of its own terminal, when the user wants to see a map image centered on the KDD building, the user adds a + sign on the screen. Just double-click on the marked part. Thereby, as shown on the left side of FIG. 17, the map image corresponding to the above-mentioned oblique aerial photograph image centered on the KDD building is displayed on the display by the position interlocking function as described above. Become.
[0044]
18 and 19 are diagrams for explaining the image enlargement and reduction functions in the present system. The left side of FIG. 18 exemplifies an enlarged map image. By double-clicking a portion with a + sign on the enlarged map image, a corresponding enlarged oblique air as shown on the right side of FIG. You can see photographic images. The left side of FIG. 19 exemplifies a reduced map image. By double-clicking a portion with a + sign on the reduced map image, a reduced diagonal image corresponding to a grab as shown on the right side of FIG. You can see aerial photo images.
[0045]
FIG. 20 is a diagram for explaining a building attribute selection display function in the present system. When the user wants to search for a destination by a building name, the target building name is selected in an attribute selection menu as shown in the upper part of FIG. 20 displayed on the display. For example, assuming that “Seven-Eleven”, “Family Mart”, and “Lawson” are selected, an attribute display setting menu as shown in the middle part of FIG. 20 is displayed on the display for each building name. For example, if “display symbol” is selected in the attribute display setting menu for each building name, a map image as shown on the left side at the bottom of FIG. 20 is displayed on the display. The symbol is affixed to the target building. Therefore, the user can intuitively grasp the location of the target building with these symbols. Then, in the same manner as described above, by double-clicking the portion with the + sign on the left map image at the bottom of FIG. 20, the corresponding oblique aerial photograph image as shown on the right side can be viewed. it can.
[0046]
FIG. 21 exemplifies an image displayed on the display when “display buildings over 30 floors” is selected in the attribute selection menu as shown in the upper part of FIG. The left side of FIG. 21 is the map image. In this map image, buildings of 30 floors or more are displayed together with the building names. When a portion with a + sign is double-clicked on the map image, a corresponding oblique aerial photograph image as illustrated on the right side of FIG. 21 can be viewed.
[0047]
FIG. 22 similarly illustrates an image displayed on the display when “display buildings of 10 floors or higher” is selected in the attribute selection menu as shown in the upper part of FIG. The left side of FIG. 22 is the map image, and buildings on the 10th floor and above are displayed together with the building names in the map image. By double-clicking a portion with a + sign on the map image, a corresponding oblique aerial photograph image as illustrated on the right side of FIG. 22 can be viewed.
[0048]
FIG. 23 is a diagram for explaining the scale bar display function in the present system. When the user wants to know the distance to the destination in the image displayed on the display, “scale bar display” is set in the scale bar display menu as shown in the upper part of FIG. 23 displayed on the display. Select and enter the desired “scale interval”. For example, an oblique aerial photograph image displayed when 100 m is input as the “scale interval” is illustrated in the lower part of FIG. This scale bar has a scroll automatic scale bar interlocking function.
[0049]
FIG. 24 is a diagram for explaining the distance grid display function in the present system. When the user wants to know the distance to the destination in the image displayed on the display, in the distance grid display menu as shown in the upper part of FIG. "And select the desired" grid spacing ". For example, an oblique aerial photograph image displayed when 100 m is input as the “grid interval” is illustrated in the lower part of FIG. Since the grid lines displayed on this image are mesh-like, they are more convenient for estimating the distance between buildings than the scale bar displayed on the image of FIG.
[0050]
Next, using this system that can deliver various images as described above, detailed destinations that are not clearly displayed on the map (here, collectively referred to as alley destinations) Explain the case of trying to reach.
[0051]
For example, the user wants to go to the “Atsugi Culture Center” located in the east side alley of “Nomura Shinjuku Building” and “Shinjuku L Tower” in the Shinjuku area. First, the user accesses the image map distribution server 100 of the present image map distribution system through the Internet 1 using a terminal such as the personal computer 20 or the mobile phone 10 owned by the user, and selects the Shinjuku area. The oblique aerial photograph image of the area can be seen on the display. The upper image in FIG. 25 is such a diagonal aerial photograph image. By selecting the enlargement function of this system, the user can display an enlarged oblique aerial photograph image as shown in the middle part of FIG. 25 on the display, and access more detailed points on the image. It becomes possible. On this enlarged image, it is possible to easily recognize which one is “Shinjuku Nomura Building” or “Shinjuku L Tower” by the building name or the like attached thereto. The destination “Atsugi Culture Center” is not clearly displayed in this enlarged image, and cannot be recognized from this enlarged oblique aerial photo image. However, since the user has the knowledge that the “Atsugi Culture Center” is located behind the alley on the east side of “Shinjuku Nomura Building” and “Shinjuku L Tower”, based on this, an enlarged oblique view in the middle part of FIG. If a portion indicated by an arrow on the aerial photograph image is clicked (alley back designation), a ground photograph image corresponding to the back alley as illustrated in the lower part of FIG. 25 is displayed on the display.
[0052]
In order to determine the location of “Atsugi Culture Center”, the user further clicks on the selected ground photograph image shown in the lower part of FIG. A terrestrial photograph image corresponding to that part can be seen. It is assumed that the user notices that there is a character that can be read as “Atsugi Culture Center” on the signboard of the building located at the back of the road in this ground photograph image. In this case, the user clicks (specifies the cursor) a portion indicated by a triangle mark on the ground photograph image on the left side of FIG. 26, so that the enlarged ground photograph of that portion as illustrated on the right side of FIG. An image can be displayed on the display, and it can be confirmed that the character displayed on the sign is “Atsugi Culture Center”, and the location of the destination can be confirmed.
[0053]
In the above example, the alley back is designated from the oblique aerial photograph image, but this system is not limited to this. You can also specify the back alley from the map image. FIG. 27 exemplifies this case, and the left side of FIG. 27 exemplifies a map image displayed in the map selection mode, and the mouse designation as indicated by an arrow on this map image is shown. The corresponding ground photograph image as illustrated on the right side of FIG. 27 can be displayed.
[0054]
FIG. 28 is a diagram for explaining a scale scroll conversion mode that can be used for an alley search in this system. In this mode, in the ground photograph image as illustrated on the left side of FIG. 28, by designating the cursor with a portion indicated by a triangle, the ground photograph image along the road can be scrolled and displayed. When the desired ground photograph image as illustrated on the right side of the screen is reached, it is possible to select and display the ground photograph image by switching to the image selection mode.
[0055]
Furthermore, a continuous enlargement scroll mode can also be used in the alley search in this system. This mode is a mode in which walk-through is performed at the same scale, the viewpoint position is set by X and Y, and the maximum enlarged photo is automatically selected as the ground photo image, and the image is switched.
[0056]
In this system, if the user desires, various images displayed on the display as described above can be printed out. FIG. 3 is an overall flow diagram collectively showing each procedure when a destination is searched using the present system as described above.
[0057]
Further, the above-described map image data may be in various formats in addition to a digital image of a normal analog map. For example, the map image data can be obtained by processing image data from a satellite image, an aerial photograph or the like. It may be a thing. The same is true for oblique aerial photo image data. Furthermore, each image data recorded in the database can be easily accommodated to cope with changes in the size and shape of buildings, redevelopment of new buildings, and new roads by redevelopment of the region. The data can be updated.
[0058]
Here, how to reach the destination at the present time, which is effective by using this system, will be described together.
(1) How to go to the site depending on the other party's lot number (local support)
a. When taking a taxi, the instructions from the landmark (department store, supermarket, etc.) are appropriate from the lot number.
b. The method of searching when walking with only a lot number is supported by a pole number display on the telephone pole (If it is a jump lot number, it enters the maze)
(2) Destination method in advance
a. Search for a road map, take a copy, and bring it to the site.
b. Knowing only the access to the nearest station and searching for the destination by relying on the map at the exit of the station (the risk is great ... the worst case would be to ask others)
c. Listen to the place (building) you know and aim for the destination (although there are few problems)
Various methods other than the method of (1) and (2) are conceivable, but (1) -a. The method of the item is often adopted by businessmen, and (1) -b. There are many other cases where the method of the term is adopted. In addition, (2) -a. And (2) -b. The method of paragraph is often used by businessmen, and (2) -c. It is assumed that there are many students who adopt the method of the section. This system is suitable for the user's preference by selecting map image data, oblique aerial photo image data, and ground photo image data recorded in various databases for reaching these diversified destinations. To make it easy to reach your destination.
[0059]
Finally, a mobile phone compatible image enlargement operation method (destination arrival method) will be described as one method for improving operability when the user accesses the system with a mobile phone.
[0060]
In the case of a mobile phone, since there is no mouse-like screen address acquisition mode, it is programmed using the keyboard so that an enlarged screen can be created at a required location by the following method. FIG. 29 is a diagram showing the same positional relationship between the keyboard layout of the mobile phone and the display screen, which will be described below with reference to FIG. 29, circled numbers 1 to 9 indicate keyboard key numbers. The diagram on the left side of FIG. 29 shows that the entire screen is displayed on the display of the mobile phone. According to this cellular phone compatible image enlargement operation method, when it is desired to enlarge and display a screen segment indicated by a circled number 1 in the entire screen in the left side of FIG. By clicking the number 1 key, a partially enlarged screen of the screen section as shown in the middle part of FIG. 29 is displayed over the entire display screen. Furthermore, when the user wants to enlarge and display the screen segment indicated by the circled number 5 in the partial enlarged screen, the right side of FIG. 29 is displayed by clicking the key of the key number 5 on the mobile phone keyboard. An enlarged screen of the screen section as shown in FIG. 6 is displayed over the entire display screen. In such an operation, when the location of the destination is finally confirmed, the confirmation image can be transmitted by keying in the transmission button.
[0061]
【The invention's effect】
Since the map image, the oblique aerial photo image, and the ground photo image can be selectively displayed, the location of the destination can be intuitively searched with an image closer to the actual situation.
[0062]
Therefore, it is possible to search for the destination without fail in a short period of time compared with the case where the destination is confirmed by relying on the conventional topographic map, house map, or road map.
[0063]
In particular, it is possible to more easily search for alleys and back destinations that are not described on a normal map.
[0064]
Because it is easy to search for such alley back destinations, it is easy for pedestrians to reach nearby destinations while using their mobile phones, and it is difficult to find destinations located in the details such as back alleys. It is possible to reach without fail.
