Description

[0001]
BACKGROUND OF THE INVENTION
According to the present invention, in a navigation device or the like that guides a vehicle to a destination along a guidance route, a user inputs an address when inputting a waypoint or a destination or displaying a map screen of a specific point. The present invention relates to an address search method and apparatus capable of easily and reliably performing an address search when a specific point is designated.
[0002]
[Prior art]
In a navigation device, a map / information storage medium such as a CD-ROM, DVD-ROM, or hard disk in which map data for drawing a map, place names displayed on the map, or information data for searching facilities, etc. is recorded Detecting the vehicle's current position and direction of travel with a playback device that reads data from this map information storage medium, a display device that displays a map, etc., a self-contained navigation device such as a distance sensor or gyro, and a GPS receiver A vehicle position detection device that reads out map data including the current position of the vehicle from the map / information storage medium, draws a map image around the vehicle position on the screen of the display device based on the map data, and The position mark is superimposed on the display screen and the map image is scrolled as the vehicle moves. Or, in or moving the vehicle position mark is fixed a map image on a screen, so that seen whether the vehicle is traveling where the current at a glance.
[0003]
In addition, the navigation device has a route guidance function for allowing the user to easily travel on the road toward a desired destination without making a mistake. According to this route guidance function, the most appropriate route is automatically searched and presented in consideration of distance, time, fee, etc. among many routes connecting from the starting point to the destination using map information, After the selection by the user, the selected route is stored as a guidance route, and while driving, the guidance route is drawn on the map image with a different color from other routes and displayed on the screen, or the vehicle guides When approaching an intersection where the course on the route should be changed within a certain distance, the intersection is enlarged and displayed on the screen by drawing an arrow indicating the direction in which the course should be changed. To guide the user to the destination.
[0004]
In order to perform the route guidance function of such a navigation device, it is necessary to first input and indicate the current location and the destination, and further, if necessary, the waypoint. At the time of the input, an accurate point can be easily instructed with respect to the current location by receiving, for example, a GPS signal. On the other hand, in order to input a destination or waypoint (hereinafter abbreviated as “destination”), for example, a method for scrolling the map screen to search for an intended point and a genre related to the destination are designated. Further, a method for searching for a destination by specifying a region, a method for specifying the latitude and longitude by directly inputting the latitude and longitude when the location or the latitude and longitude of the location in advance are known, and a purpose for inputting the postal code A method for specifying the vicinity of a place, a method for specifying a point by inputting a telephone number of a destination or a facility in the vicinity thereof, a method for specifying a point by directly inputting a point name, a facility name, an individual name, etc., a purpose Various methods have been proposed, such as a method of selecting and instructing the local address in order from the prefecture displayed on the screen to the detailed spot name.
[0005]
Each of these methods has advantages and disadvantages, but many of them are used in daily life and children in order to specify the destination address in order from the prefecture displayed on the screen. When dealing with postal items, requesting transportation of goods, etc., the location is specified by address in various cases, etc., and since this is familiar, this address search when specifying the destination This method is often used.
[0006]
There are various methods for performing address search, for example, a method of directly inputting an address using the character keys of the remote control, or after first displaying a selection screen of a prefecture and the user selecting one By displaying the list of subordinate place names on the monitor screen in order, such as presenting the municipality existing in the prefecture, scrolling appropriately and selecting the desired municipality, the final selection is made. There are methods for inputting a desired point.
[0007]
In addition, when performing address search, in the navigation device as described above, in addition to inputting the destination of the guidance route, when displaying a map screen of a specific point, or when displaying facilities at a specific point, etc. There are such requirements in various cases. Furthermore, such a display of a map screen or a search based on the address of a specific facility is not limited to the navigation device as described above. For example, a map of a specific point is displayed on a map information providing site on the Internet, or a specific site is searched. It is also used in the same manner when searching for a facility and displaying a map screen centering on the facility or displaying information.
[0008]
For example, Patent Literature 1 discloses a technique in which a wide-area address portion is designated by selecting a map display portion and a boundary-area address portion is selected from a list-displayed address when searching for an address.

[0010]
[Problems to be solved by the invention]
Among various methods for performing such address search, the key input method can accurately input a desired point when the destination address is accurately known in advance. However, it is difficult to accurately input complicated place names, and it is often troublesome because it is necessary to frequently convert kana-kanji characters. On the other hand, the method of selecting the place names in order by selecting place names displayed on the monitor screen is appropriate by selecting from the place names displayed even if the place names are not remembered correctly. A place name can be specified. However, when the place name is not remembered very accurately, the above selection cannot be performed, and the place name cannot be input thereafter.
[0011]
In particular, Japan's place names are formed by the hierarchy of prefectures → municipalities → large letters → small letters chome → branch numbers → house numbers, but among the above, it is a wide area address to prefectures, municipalities, and large letters. Top addresses are maintained throughout Japan, and map data for navigation devices is created almost exactly correspondingly, so there is little problem in practical use.
[0012]
However, the following sub-addresses, branch numbers, and low-order addresses that are narrow addresses of house numbers are not necessarily arranged in this order. There are cases where there are only branch numbers and house numbers after the large letters. In addition, in the case of Yamamura, there is no small chome and branch number after the large character, and there is data that becomes a door number immediately after the large character. Similarly, there is a case where there is no branch number after the small crest and a house number follows.
[0013]
As mentioned above, in particular, the address hierarchy of the lower address of the small chome → branch number → house number may not always be given the actual place name itself, but for map data used in the navigation device, When the data is created, data is not correctly assigned to these hierarchies and may be mistakenly assigned to other hierarchies.
[0014]
Therefore, when the method of directly inputting an address by key input as described above is adopted for address search, especially for the address hierarchy of the lower address, even if the user inputs without error, the data recording medium is used. Since it may not match the recorded address data, the point cannot be indicated. In addition, even if there is a slight error in the hierarchy at the lower address of the address that the user has previously described as a postal address, the error is often obvious to the local postman and is definitely delivered. There are many. Therefore, the user may misunderstand that the address is correct. Even in such a case, if the user performs a search by keying in the address, a search result that there is no matching data when the map data is accurate will be obtained.
[0015]
For the method of displaying place names in order from the prefecture to the lower address on the monitor screen and sequentially specifying by the user, for example, the address stored as “XX city △△ town 11-12” is stored. When inputting, there is a case where it is not known which address hierarchy should be assigned to 11-12, which is not preferable. In addition, when inputting, it is necessary to select from a large number of address candidates for each layer, and there is a problem that an operation such as screen scrolling is necessary and the number of operations increases.
[0016]
Therefore, the present invention provides an address search method capable of reliably and easily searching for a point even when a user does not accurately remember a lower address when performing an address search, and an apparatus for implementing the method. The main purpose is to do.
[0017]
[Means for Solving the Problems]

[0024]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a functional block diagram showing the mutual relationship by blocking various functions in an example in which the address search method according to the present invention is applied to a navigation device, particularly focusing on various functional units that implement the address search method according to the present invention. FIG. In addition, each function part in the figure can be paraphrased as means for performing each function.
[0025]
In the navigation apparatus shown in FIG. 1, a vehicle position detection unit 3 that detects the current position of a vehicle by inputting signals from a GPS receiver 1 and a travel distance / orientation detection unit 2. An instruction signal input unit 4 for inputting an instruction signal by recognition or the like is provided. Therefore, it is possible to move the cursor displayed on the monitor screen by the instruction signal input unit 4, move the operation unit, make various selections and confirmations, and search for an address as will be described later using a numeric keypad or a character key of a remote controller or the like. It is possible to input various numbers.
[0026]
Further, for example, a map / information data recording medium 5 in which map data and various facility information are recorded on a CD-ROM, DVD-ROM, hard disk or the like, and data capture for reproducing the map data and facility information by reproducing it. Part 6 is provided. Further, the guidance route calculation unit 7 records the current position detected by the vehicle position detection unit 3, the destination and waypoints input by the user from the instruction signal input unit 4 by various methods such as address search, and the map / information record Data of the medium 5 and the like are input through the system control unit 20, and various guidance routes such as the shortest distance, the shortest time, and the shortest expense are calculated and presented to the user.
[0027]
Of the various routes calculated in this manner, the route selected by the user is determined and stored as a guidance route, and the voice output unit 11 continues until the vehicle arrives at the destination from the current location by the guidance route guidance unit 8. Guidance is performed by guidance by the speaker 10 or by outputting a guide image from the image output unit 13 to the monitor 12. In addition, an instruction related to the search specified by the user using the instruction signal input unit can be displayed on the screen of the monitor 12 from the image output unit 13 after the search described later.
[0028]
The address search processing unit 21 that performs an address search according to the present invention includes an address input detection unit 22 that detects data related to an address input by the user from the instruction signal input unit 4 as an overall configuration. Data relating to the address designated by the operator is sent to the search condition output unit 30, and the address data search unit 31 stores the data in the map / information data recording medium 5 in accordance with the search condition output from the search condition output unit 30. 6. The data is retrieved via the system control unit 20 and the corresponding data is retrieved from the address data.
[0029]
The address searched by the address data search unit 31 is output to the search result list creation unit 32, a predetermined image is formed by the search result list image creation unit 33, and the monitor 12 passes through the system control unit 20 and the image output unit 13, respectively. Is displayed. Further, when the user selects a predetermined address by looking at the search result list and designates it as a confirmed address, the user inputs this in the confirmed address instruction input unit 34 and a plurality of candidates existing in the search result list creation unit 32 The fixed address output unit 35 selects and outputs a specific address among the addresses. This confirmed address is output as data of a destination or waypoint of, for example, the guidance route calculation unit 7 connected to the system control unit 20. Further, for example, when a specific point map screen display request is made, the fixed address is used as a display instruction point, and a map of the point is read from the map / information data recording medium 5 by the data acquisition unit 6 and displayed on the monitor 12. Done.
[0030]
The address input detection unit 22 includes “prefecture, city, etc.” corresponding to a wide-area address in an address hierarchy such as “prefecture → city / town → large letter → small letter chome → branch number → house number” in the address. Upper address input detection unit that detects the upper address selected and input by the user according to the selection screen in which the lower address is displayed in order from the prefecture, for example, on the monitor screen. 23 and a lower address input detection unit 24 that detects lower-layer address inputs such as “small letters, branch numbers, and house numbers” corresponding to addresses in a narrow area by a method described later.
[0031]
The lower address detection unit 24 includes a lower address ambiguous input detection unit 25. In the illustrated example, the lower address ambiguous input detection unit 25 is provided with a delimiter mark “-” as described later in order to enable various types of ambiguous input. An input detection unit 27, a wild card “*” input detection unit 27, and a kana input detection unit 28 are provided.
[0032]
The address search processing unit 21 including the various functional units as described above can be operated in sequence by, for example, an operation flow shown in FIG. The operation flow will be described below with reference to the functional block diagram of FIG. 1 and the examples of FIGS. FIG. 2 shows the ambiguous address search process in which the user can mainly search for an address that the address is only ambiguously remembered in the address search process. First, a high-order address that is a wide-area address in prefectures, cities, towns, and villages, which is a range that is almost certainly remembered by the user, is input by various conventional input operations.
[0033]
When inputting the upper address, for example, as shown in the monitor screen example of FIG. 4A, the user scrolls appropriately from a list in which prefectures are arranged in alphabetical order as shown in the left screen of FIG. Thus, for example, a desired upper address such as “Tokyo 23 Wards” is selected. When the selection is confirmed, a map of the point as shown in the right screen of the figure is displayed so as to be distinguishable from others, and is confirmed by the user. Thereafter, a selection screen for the wards included in the 23 wards of Tokyo as shown in FIG. 4B is displayed. After appropriate scrolling, “Shinagawa ward” is selected from the screen in the illustrated example. As a result, on the right screen, the position of Shinagawa Ward in Tokyo 23 Ward is displayed so as to be distinguishable from others, and is confirmed by the user.
[0034]
After that, a place name list in this Shinagawa ward is displayed in the same manner as described above, and by selecting a place name intended by the user from the list, the upper address predetermined input operation in step S1 is completed. In the above example, as an upper address predetermined input operation, the address list screen is displayed in order from the prefecture, and the user selects this to input, but in addition, the map screen of the entire Japan first is displayed. The method is conventionally performed, such as a method in which a user designates a region or prefecture in the area, and then displays an enlarged map of the area or prefecture, and then designates the upper hierarchy in order. It can be input by any method. These higher-order address inputs are detected by the higher-order address input detection unit 23 in the address input detection unit 22 shown in FIG. 1, and are output from the search condition output unit 30 to the address data search unit 31. It is used as data for limiting the area.
[0035]
Next, the fuzzy search input of the lower address is performed (step S2). Although the details of the subordinate address ambiguous search input will be described later, the outline is, for example, that the user is an array of the numbers “1112” despite the address that is exactly 1-chome 1-12. If you only remember, enter "1112". In the above example, when the user remembers the sequence of numbers “1112” and the numbers before and after the number separator “−” such as “1-1” in the first part of the sequence, 1-11-2 ".
[0036]
In the above example, when the user only remembers the first 1 and the last 2, the user uses the wild card “*” and inputs “1 * 2”. Furthermore, if you remember that a part of this sub-address contains a kanji called “ko” and remember that the number 1 was connected before that, Enter "*". In addition, these can be combined as necessary, or various fuzzy search inputs of other modes are possible. These lower address ambiguous inputs are performed in the lower address ambiguous input detection unit 25 in the lower address input detection unit 24 in FIG.
[0037]
After the fuzzy search input of the subordinate address is performed in step S2, it is determined whether or not the input of the format "(A)-(B)" is performed using the delimiter mark "-" in the illustrated example. (Step S3). If it is determined that the delimiter mark “-” is not used, the process immediately proceeds to step S4. If it is determined that the delimiter mark “-” is used, the process proceeds to step S8 to instruct to perform an integrated search for “AB” as will be described later, and then proceeds to step S4. The instruction of the search method in step S8 is instructed as a search condition when executing the search in step S7 as will be described later. Whether or not the delimiter mark “−” has been input is determined by the delimiter mark “−” input detection unit 26 in FIG.
[0038]
In step S4, it is determined whether or not an input of the format “(A) * (B)” using the wild card “*” has been performed. If it is determined that the wild card “*” is not used, the process immediately proceeds to step S5. If it is determined that the wild card “*” is used, the process proceeds to step S9 to determine the preceding and succeeding A and B, as will be described in detail later, and to instruct retrieval of all data between them, and then to step S5. Proceed to The search instruction here is also instructed at the time of execution of the search in step S7 as described above. Whether or not the wild card “*” is used is determined by the wild card “*” input detection unit 27 in FIG.
[0039]
In step S5, it is determined whether or not a pseudonym has been input. If it is determined that no pseudonym has been input, the process proceeds to step S6. If it is determined that a kana has been input, the process proceeds to step S10 to instruct to search for data including the reading kana of the input kana as described later, and then the process proceeds to step S6. This search instruction is also instructed when the search is executed in step S7. Whether or not this kana input has been performed is performed by the kana input detection unit 28 of FIG.
[0040]
In step S6, for numbers, kana, or symbols entered by the user, data including both cases where there is a delimiter between the input digits except for the input part with the above-mentioned various conditions. Instruct to search. Step S6 is the basis for this fuzzy search input and search based on the input. The lower address of the area specified by the higher address input is, for example, address data as shown in FIG. When it exists and is stored in a map / information storage medium, etc., if you enter “1112”, it is treated that the numbers and their order are correct, but the separator between the numbers is unknown. Therefore, “1-1-1-2” in which all delimiters “−” exist between the numbers, or “1-1-12”, “1-11-2”, “11-1-” with only two delimiters. 2 ”,“ 111-2 ”,“ 11-12 ”,“ 1-112 ”with only one delimiter, or“ 1112 ”with no delimiters. All addresses that meet An instruction to search from the data. In addition, the order of each process of above step S3, step S4, and step S5 is not ask | required.
[0041]
In a state in which such various instructions are performed, the search is executed under all the instruction conditions in step S7. In this search, the various search conditions collected in the search condition output unit 30 in FIG. 1 are output to the address data search unit 31, and the address data search unit 31 stores the data in the map / information data recording medium 5 according to those conditions. Use to search. As a result, for example, when it is determined in step S3 that the delimiter mark “-” is not input, it is determined in step S4 that the wild card “*” is not input, and in step S5 it is determined that no kana is input. When “1112” is input as described above, as shown in FIG. 3B, “1-1-1-2”, “1-1-12”, “1-112”, “11-12” “111-2” is retrieved and extracted. This search method is used in the same manner except for the search portion of the specified portion in various fuzzy search inputs described later.
[0042]
On the other hand, in step S3, it is determined that “(A)-(B)” with a delimiter has been input, and the process proceeds to step S7, where “AB” is handled as integral data to be searched. When the user is instructed, for example, in the above example, the user places a sequence of numbers “1112” and a number separator “−” that is “1-1” in the first part of the sequence. If you remember the number “1-1” before and after “,” you would enter “1-112”, but for “1-1” part, the characters before and after the delimiter mark “-” and the delimiter mark And (1-1) as a single character, while the other “112” part has a delimiter between each input digit as described in the description of step S6. If and exist Performing a search as data including both cases are.
[0043]
Therefore, “(1-1) -1-2”, that is, “1-1-1-2”, in which all (two) delimiters are present, and “(1-1) 1-2, in which only one delimiter mark is present, exist. “1-11-2” and “(1-1) -12”, ie “1-1-12”, and “(1-1) 12”, ie, “1-112”, which has no delimiter marks. Assuming any one of the four types in total, all addresses that match these are searched from the stored data. As a result, in the example shown in FIG. 3, "1-1-1-2", "1-1-12", "1-112" are searched and extracted as shown in FIG. Become. In this way, by inputting a delimiter that is slightly known by the user, the amount of search data can be greatly reduced as compared to a case where no input is made at all.
[0044]
In step S4, using the wild card “*”, it is determined that the input of the format “(A) * (B)” has been made, and the process proceeds to step S9. A and B before and after the wild card “*” are When it is confirmed and a search instruction for all data in between is given, the first address of the lower address is “A” and the last is “B”, and there is any data between A and B. Search as possible. Therefore, for example, when “1 * 2” is input in the above example, all the data having “1” at the beginning and “2” at the end of the lower order data are searched. In the example of FIG. As shown in (d), “1-1-1-2”, “1-1-12”, “1-1-2”, “1-1-2” that match the above conditions from the stored data in FIG. “2-2”, “1-112”, “11-12”, and “111-2” are searched and extracted.
[0045]
If it is determined in step S5 that a kana has been input, the process proceeds to step S9. If a search for data including the reading kana of the input kana is instructed, for example, the “k” kana in the input input data for search is input. In the example of FIG. 3A, “Extra”, “Saddle”, etc. are searched and extracted. Therefore, for example, when “1 *” is input, as described above, both “1” and “1” are searched for both when the delimiter mark “-” exists and when it does not exist. Therefore, as indicated in the step S9, all data are to be searched for the portion of “*”. In such conditions, “1” is followed by “ko” or “ Search for kana characters whose reading begins with "ko". In step S7, as a result of the search under such comprehensive conditions, as shown in FIG. 3 (e) from the data in FIG. 3 (a), “1-E-31”, “1-E- 36 ”and“ 1- 紺 -10 ”are retrieved and extracted.
[0046]
After performing a search under the conditions of various search instructions as described above in step S7, a list of the search results is created and displayed (step S11). This list is created in the search result list creation unit 32 in FIG. 1, and the display screen is created in the search result list image creation unit 33.
[0047]
For example, the list is displayed as shown in FIG. FIG. 5 (a) shows a state where an ambiguous address search is instructed in advance, and after selecting and inputting the upper address in accordance with the screen display in order from the prefecture as shown in FIG. This is an example of a screen that is automatically displayed when it becomes, and shows a state where “1112” has already been input as an ambiguous address. In this example screen, “Shinagawa-ku Nishi-Gotanda, Tokyo”, which is the result of the previous high-level address input, is displayed, indicating that subsequent searches will be performed within this range. The example which requested | required to input suitably the address of is shown.
[0048]
As a result of performing the above-mentioned ambiguous address search input, as shown in FIG. 5B, “1-1-1-2”, “1-1-12”, “1-112”, “11-12”, “11-12” "111-2" is retrieved, extracted, listed, and displayed. In such a display, although the user did not memorize correctly, he / she remembered that it was “1-1-12” by seeing this display, and by selecting this with the cursor and confirming it, You can enter a valid address. In the figure, for the convenience of the user, an example is shown in which the upper address input display and the key input performed by the user are displayed on the right screen.
[0049]
The address search method according to the present invention is not limited to the above-described embodiments, and may be implemented in various modes, for example, the upper address is performed at a lower address stage or the upper address stage. can do. Further, such an address search method is not limited to the navigation device as described above, and can be used in a wide range of fields such as search using map software on a personal computer, use on a map search site on the Internet, and the like.
[0050]
【The invention's effect】
The address of the wide area is instructed by the upper address input means according to the present invention, the address of the narrow area is instructed by the lower address input means for inputting characters without a delimiter, and within the range of the upper address designated by the upper address input means The address search method for searching for and listing all of the characters with and without a delimiter between the non-delimited characters from the address data, the high-order address input means for indicating a wide area address, and the narrow area address Lower address input means for inputting characters with no delimiters, and within the range of the upper address designated by the upper address input means, all of the ones with and without delimiters between the non-delimited characters are taken from the address data In the address search device including the address data search means for searching and the search result list creation means for listing the results searched by the address data search means, both of the data are stored in the lower hierarchy. Even if it is difficult to search with the conventional address search method because it often does not exist, you can simply and quickly and accurately search by simply entering the characters stored in the order in which they are stored. It can be performed, and can be used effectively in address search of various devices including a navigation device.
[0051]
In addition, the upper address input means designates a wide area address, the lower address input means for inputting characters or symbols inputs a wild card symbol, and the wild address is within the range of the upper address designated by the upper address input means. An address search method for searching and listing from address data as including all characters and symbols in the part where the card symbol is input, a high-order address input means for indicating a wide area address, and a character or wildcard symbol The address data is assumed to include all characters and symbols in the part where the wildcard symbol is input within the range of the upper address designated by the upper address input means and the lower address input means for inputting the symbol including An address search device comprising address data search means for searching from, and search result list creation means for listing results searched by the address data search means In any case, it is easy to search for a desired address because all addresses are not clearly remembered by simply entering a wildcard symbol, and the corresponding addresses are searched and presented as a list. Can do.
[0052]
Further, in the address search method, a delimiter mark is input by the lower address input unit, and characters before and after the delimiter mark and the delimiter mark are set to one character within the range of the upper address designated by the upper address input unit. In the address search method and the address search device, the lower address input means can input a delimiter mark, and the address data search means allows the upper address specified by the upper address input means In the address search device in which the character is searched with the character before and after the delimiter mark and the delimiter mark as one character within the range, by inputting the delimiter part stored by the user as the delimiter mark , Search data will decrease, search efficiency will improve, and the address of search results will decrease, making it easier for users to use Kill.
[0053]
Further, in another address search device according to the present invention, in the address data search means in the address search device, the address including the pseudonym and the pseudonym are within the range of the higher address designated by the higher address input means. Since the kanji used as the reading kana is searched, even if a kanji exists in the lower address, it is possible to search for an appropriate address only by entering a part of the reading kana, which is highly usable. It can be set as an address search device.
