The scope of the present invention is defined by the appended claims.
The technical scheme provided by the invention is based on the fact in the prior art that an electronic map service provider already reduces an administrative district address library and a detailed address library, wherein the administrative district address library comprises databases of provinces, cities, districts/counties and streets/towns, and the detailed address library comprises databases of addresses of subdistricts (such as No. 22, building 1, unit 17, layer 01 of a peony garden), addresses along streets (No. 56 of a college road) and the like. In order to perform accurate goods delivery, information such as a cell, a building name, a building number, a unit number, a floor, a room number and the like needs to be provided in the logistics system. In an indoor navigation application scene, the target address can be also divided into a building name, a building number, a floor, a room number and the like, the same building name, building number and floor information in the address of the facility are edited into one floor, the information is displayed in a map according to different coordinates of each facility, and meanwhile, the detailed room number information of the facility can be displayed, so that people can conveniently and visually browse the facility of each floor.
By splitting the address, the accurate address of goods delivery can be selected from the address library, the efficiency of goods delivery can be improved in a logistics system, and the goods are guaranteed to be distributed to corresponding delivery points. In the navigation map, the addresses of points of interest (POI) are split, so that when a courier uses the map for navigation delivery, the addresses filled in by the user can be accurately matched with the addresses in the navigation map, and the courier can plan the route by means of navigation software and deliver the goods to the home of the consumer in time.
Fig. 1 shows a flowchart of an address refinement processing method for positioning and navigation provided by the present invention, which includes:
105, acquiring a target address full name; the target address can be an address input by a user or an address collected by a service provider;
and step 115, aiming at the matching result, adopting different splitting modes according to different conditions, splitting the matching result into a plurality of parts, and carrying out address structure refinement treatment on the parts by utilizing a preset keyword table to obtain a refined target address for carrying out precise positioning navigation and storing the refined target address into map data.
For example, if there is a matching one, the road name may be taken as a part, the address after the road name as a part, and the address before the road name as a part; if a plurality of matched road names exist, taking the road names and characters between the road names as a part, taking the address before the first road name as a part, and taking the address after the last road name as a part; if there is no matching road name, but the destination address has a keyword related to the road name, such as a road, street, lane, road, etc., the address following the keyword is a part, and the remaining part containing the keyword is a part; if there is no matching road name and the target address also has no keywords related to road names, such as road, street, lane, road, etc., then the target address is integrated into one part; after splitting into one part, two parts or three parts, the parts are respectively split according to keywords, for example, the parts after the road name are split into house numbers, types, prefixes, suffixes, auxiliary facilities, building numbers, unit numbers, room numbers, additional information and the like, the part containing the keywords, the part before the road name or the whole address name is according to province names, city names, districts/counties, towns/streets and place names/cell names, and the split address can be used for positioning or navigation.
At present, the mobile phone can only be split to a township, and the detailed address below the township is not split as a part, so that the mobile phone is not beneficial to accurate positioning. The embodiment not only splits province, city, district/county and township, but also splits information such as street, building and indoor facilities, and not only facilitates more accurate positioning, but also can perform accurate navigation.
According To the embodiment, the target address is split through the road name database and the keywords, the split address can be used for improving the efficiency and accuracy of the logistics sorting service, and the accurate navigation of the To Door can be realized.
As an optional implementation manner, based on the foregoing embodiment, the address refinement processing method for positioning and navigating may further include:
step 120, establishing position coordinates of indoor facilities in a hierarchical level in advance, and embedding indoor map data correspondingly in advance;
and step 125, performing refinement processing on the address of the indoor facility to obtain a refined target address of the indoor facility.
As an optional implementation manner, based on the foregoing embodiment, the address refinement processing method for positioning and navigating may further include:
step 130, according to the refined target address, detecting that a navigation target address is partially or completely the same as the refined target address, and generating an alternative navigation address for a user to select;
as an optional implementation manner, based on the foregoing embodiment, the address refinement processing method for positioning and navigating may further include:
and 135, performing accurate positioning navigation detection according to the refined target address, and displaying the information of the indoor facilities by floors when performing indoor accurate positioning navigation detection.
Therefore, by the address refinement processing method for positioning and navigation disclosed by the embodiment, not only is the address structure refined and graded, and the efficiency and the accuracy of the logistics sorting service are improved, but also the automatic selection of the online shopping address can be realized based on the POI address structure refinement, and the intuitive layered display of the indoor map can be realized based on the POI address structure refinement, so that people can intuitively and quickly browse each layer of facilities, and the accurate navigation of the indoor map is realized.
The following further describes an embodiment of the address refinement processing method for positioning and navigation with reference to fig. 2, where fig. 2 is a schematic flow chart of the address refinement processing method for positioning and navigation provided by the embodiment of the present invention, and the address refinement processing method for positioning and navigation includes:
step 225, regarding the road name as a part;
255-270, splitting the address before the road name into a provincial name, a city name, a district/county name, a town/street handling name and a place name/cell name;
275-297, splitting the street name post-address into house number, type, prefix, sub-number, suffix, affiliated facility name, building number, floor number, unit number, room number, and additional information;
All addresses can be split before specific application so as to be applied to specific positioning or navigation scenes, or the addresses input by a user can be split after being received so as to provide accurate positioning or navigation services for the user, such as goods delivery, or the collected addresses are split in data before application, split after being received, and then matched so as to provide the positioning or navigation services for the user.
First, when address splitting is performed before a road name, a place name/cell name can be split according to the following manner.
A. For example, in the case where there is a matching road name:
1.1 get the "place name/cell name" field of the "POI address" list and the administrative division of the POI in the database, if the address name before the road name matches with the "place name/cell name" of the database (preferably takes the longest priority), then the matched place name or cell name is used as the place name/cell name, if there are multiple place names/cell names matching the same, the characters between the multiple place name cell names and cell names are used as the place name/cell name.
1.2, acquiring POI names classified into cells and administrative regions of the POI in a POI table of a database, if addresses before road names are matched with the POI names (the address is the longest in priority), taking the matched region names or cell names as region names/cell names, and if a plurality of matched same region names/cell names exist, taking characters between the region names/cell names and the region names/cell names as characters.
1.3 matching with the place name keywords (district, village, development area, scenic spot and high new district) from right to left. If there is a matching key (subject to the last key), the key and the address before the key are used as the address before the location/cell name.
Through the steps, the following resolution results can be obtained:
the matching place name/cell name exists in the place name/cell name in the POI address table and the POI table, and the matching place name/cell name exists in the POI address table and the POI table.
The matching place name/cell name can not be found in the POI address table and the POI table, but keywords related to the place name/cell name exist, and the method is divided into the following steps: location name/pre-cell name address (containing key).
And finding out no matched place name/cell name in the POI address table and the POI table, and taking the full field as the address before the place name/cell name without splitting when no key words related to the place name/cell name exist.
B. For example, in the case where there is no matching road name, but there is a keyword with the road name:
2.1 get the "place name/cell name" field and the administrative division of the POI in the "POI address" table of the database, if the address before the road name matches with the "place name/cell name" in the database (preferably takes the longest priority), then take the matched place name or cell name as the place name/cell name, if there are multiple same place names/cell names, take the characters between multiple place names/cell names and place names/cell names as the place name/cell name.
And 2.2, acquiring POI names of cells and administrative regions of the POI classified in the POI table of the database, if the addresses before the road names are matched with the POI names (the address is the longest in priority), taking the matched place names or cell names as place names/cell names, and if a plurality of place names/cell names which are matched with each other are the same, taking characters between the place names/cell names and the place names/cell names as the place names/cell names.
2.3 matching with the place name keywords (district, village, development area, scenic spot and high new district) from right to left. If the matched keyword exists (the last keyword is taken as the standard), the matched keyword and the character before the keyword are taken as the address before the place name/the cell name. If not, the whole road pre-name address is used as the location name/cell pre-name address.
Through the steps, the following resolution results can be obtained:
finding out a matched place name/cell name from the cell names in the POI address table and the POI table, and splitting into: location name/cell name, location name/pre-cell name address.
The matching place name/cell name can not be found in the POI address table and the POI table, but keywords related to the place name/cell name exist, and the method is divided into the following steps: the address before the place name cell name (containing the key).
And finding out no matched place name/cell name in the POI address table and the POI table, and taking the full field as the address before the place name/cell name without splitting when no keywords related to the place name/cell name exist.
C. For example, in the case where there is no matching road name and there is no keyword with the road name:
3.1 get the "place name/cell name" field and the administrative division of this POI in the "POI address" table of the database, if the address matches (preferentially takes the longest) with the "place name/cell name" of the database before the road name, regard the place name or cell name that matches as the place name/cell name, if there are multiple place names/cell names that match the same, regard characters between multiple place names/cell names and place names/cell names as the place name/cell name.
And 3.2, acquiring POI names classified into cells and administrative regions of the POI in the POI table of the database, if the address before the road name is matched with the POI name (the address is the longest in priority), taking the matched place name or cell name as the place name/cell name, and if a plurality of place name cell names which are matched with each other are present, taking characters between the place name cell names and the place name/cell names as the place name/cell name.
3.3 matching with the place name keywords (district, village, development area, scenic spot, high new district) from right to left. If the matched keyword exists (the last keyword is taken as the standard), the matched keyword and the character before the keyword are taken as the place name/the cell name. If no matching keyword exists, the road pre-name address is used as the place name/cell name.
Through the steps, the following resolution results can be obtained:
finding out matched place names/cell names in the POI address list and the cell names in the POI list, and splitting the place names/cell names into: location name/cell name, location name/pre-cell name address.
The matched place name/cell name can not be found in the POI address table and the POI table, but the place name/cell name key words exist, and the division is as follows: the address before the place name cell name (containing the key).
And finding out no matched place name/cell name in the POI address table and the POI table, and taking the full field as the address before the place name/cell name without splitting when no keywords related to the place name/cell name exist.
Secondly, when splitting the address before the location name/cell name, splitting the location name/cell name according to the following modes:
and under the condition that the matched road name and the matched place name/cell name are found in the database, matching the address before the place name/cell name with the administrative division of an administrative division table, splitting the address from left to right into a province name, a city name and a district/county name, and splitting the country name/street name under the condition that a keyword 'village, town and street' exists. Through the steps, the following resolution results can be obtained: provincial, city, district/county, town/street.
When a matched road name is found in the database, but a matched place name/cell name is not found and a keyword related to the place name/cell name exists, the address before the place name/cell name is matched with the administrative division of the administrative division table, the address is split into a province name, a city name and a district/county name from left to right, when the keyword 'village, town and street' exists, the town/street handling name is also split, characters behind the town/street handling name are used as the place name/cell name, the town/street handling name and characters in front are used as the town/street handling name, and when the keyword 'village, town and street' does not exist, characters behind the district/county are used as the place name/cell name. Through the steps, the following resolution results can be obtained: a province name, city name, district/county name, town/street name, place name/district name; b province name, city name, district/county name, place name/cell name.
When splitting the address behind the road name, the following processing can be performed:
the address format after the road name is not unified at present, and according to practical experience, the address format after the road name can be regarded as a doorplate character string by starting with numbers or letters, and connecting a string of the characters with the value ranges of numbers, letters, -, "/", "" (middle cross bar). The first doorplate character string is found from left to right of the address behind the road name, and the 'type' is connected behind the 'doorplate character string', so that the 'number' is considered (for example, the '3-A number', '3-8-6' is a doorplate, and '3-3' is not a doorplate). Is a house number, and the characters before the 'house number character string' are used as prefixes; splitting the doorplate character string; "type" includes "number, yard", and the like.
In splitting, if the digit string is at the end of the address, i.e. there is no content behind it, the digit string is taken as the house number. If the number string is followed by the content, judging whether the content following the number exists in the type library, if so, taking the number string as the number and the type word as the type of the number. Further, the house number and the type can be divided into a house number, a type and a sub-number, wherein the type can be null.
Through the splitting, the characters in the address behind the road name before the house number character string can be used as prefixes, such as A, B and C; the house number character string can be divided into house number, type, sub-number, address behind the sub-number, etc.
Fourthly, when splitting the address behind the sub-number, the following processing can be carried out:
the address behind the sub-number is matched with a subsidiary facility name keyword (for example, a building or a shopping mall), and if the matched keyword exists, the matched keyword and the preceding content are used as the subsidiary facility name. Through the above processing, all addresses behind the sub-number can be used as the names of the affiliated facilities, or the addresses are divided into the names of the affiliated facilities and the addresses behind the names of the affiliated facilities, and the specific processing can be determined according to the addresses behind the sub-number, if the last character of the addresses behind the sub-number is a keyword, the addresses behind the sub-number are used as the names of the affiliated facilities, otherwise, the addresses are continuously divided.
And fifthly, when splitting the address behind the affiliated facility name, processing the address according to the following mode:
the address behind the affiliated facility name is matched with a building keyword (such as a building), and if the matched keyword exists, the matched keyword and the front content are used as a building number. Through the processing, all the addresses behind the names of the auxiliary facilities can be used as the building numbers, or the addresses are split into the building numbers and the post-building-number addresses, the specific processing can be determined according to the addresses behind the names of the auxiliary facilities, if the last characters of the addresses behind the names of the auxiliary facilities are keywords, the addresses behind the names of the auxiliary facilities are used as the building numbers, and otherwise, the splitting is continued.
Sixthly, when splitting the address behind the building number, processing can be carried out according to the following mode:
the address at the back of the building is matched with the keyword (such as a skirt) of the unit number, and if the matched keyword exists, the matched keyword and the front content are taken as the unit number. Through the processing, all the post-address of the building number can be used as the unit number, or the post-address can be split into the unit number and the post-address of the unit number, the specific processing can be determined according to the post-address of the building number, if the last character of the post-address of the building number is a keyword, the post-address of the building number is used as the unit number, and if not, the splitting is continued.
And seventhly, when splitting the address behind the unit number, processing can be carried out according to the following mode:
the address behind the unit number is matched with a floor keyword (such as a floor), and if the matched keyword exists, the matched keyword and the front content are used as the floor number. Through the above processing, all the post-address of the unit number can be used as the floor number, or the post-address can be split into the floor number and the post-address of the floor number, and the specific processing can be determined according to the post-address of the unit number, if the last character of the post-address of the unit number is a keyword, the post-address of the unit number is used as the floor number, otherwise, the splitting is continued.
Eighthly, when splitting the address behind the floor number, processing can be carried out according to the following mode:
the post-floor address is matched with the room number key (e.g., 301, 302), and if there is a matching key, the matching key is taken as the room number. Through the processing, all rear addresses of the single floor number can be used as the room numbers, or the rear addresses can be split into the room numbers and the additional information, the specific processing can be determined according to the rear addresses of the floor numbers, if the last characters of the rear addresses of the floor numbers are keywords, the rear addresses of the floor numbers are used as the room numbers, and otherwise, the rear addresses of the floor numbers are continuously split into the room numbers and the additional information.
After the addresses in the POI address library are finely split, the address library can be provided for a logistics company and a navigation map, the logistics company provides consumers with mailing addresses to a building by utilizing the POI addresses in a fine grading manner, so that errors of manual filling are avoided, and errors of system distribution of express are avoided; the navigation map utilizes the POI address to carry out fine grading to accurately match the destination retrieval to the building number and carry out accurate navigation.
In a logistics application scene, a place name/cell name, a house number, a building name, a unit number and a room number can be selected through a pull-down menu, so that missing filling is effectively prevented, inaccurate and detailed filling is avoided, logistics distribution errors are caused, and the logistics transportation efficiency is reduced. Based on the detailed facility addresses accurate to the number of the building, the unit number, the floor and the room number of the community, the system can accurately deliver goods to the home in express delivery, and the user can easily enjoy the convenience of internet service without going out.
In the indoor navigation application scene, the indoor navigation applies the most advanced indoor positioning technology and cannot accurately split the detailed facility addresses of the building name, the building, the floor and the room number. The facilities are edited into one floor by using the same building number and floor information in the facility address, and are displayed in a map according to different coordinates of each facility, and meanwhile, the detailed room number information of the facilities can be displayed. And the device is convenient for people to visually and quickly browse facilities on each layer.
As an optional implementation manner, in an indoor navigation application scenario, the address refinement processing method for positioning and navigation provided by the present invention may further establish position coordinates of the indoor facility in advance in a hierarchical manner, and embed indoor map data in advance correspondingly, and obtain a refined target address of the indoor facility by performing refinement processing on the address of the indoor facility. In addition, the method can also detect that the navigation target address is partially or completely the same as the refined target address according to the refined target address, and generate an alternative navigation address for the user to select; when accurate positioning navigation is carried out indoors, information of indoor facilities is displayed by floors.
In order to implement the above method, the present invention provides an address refinement processing apparatus for positioning and navigating, as shown in fig. 3, the apparatus includes: an acquisition module 305, a matching module 310, a splitting module 315, and a storage module 320. An obtaining module 305, which may be used to obtain a target address full name, such as an address input by a user or an address in an address database; the matching module 315 may match the full name of the target address with the road name in the road name metadata table; the splitting module 320 may split the target address into a plurality of parts according to the matching result, and perform refinement processing on the plurality of parts by using a preset keyword table to obtain a refined target address for precise positioning and navigation; the storage module 325 may store the obtained refinement target address.
The matching module 310 performs matching using road names in the road name metadata table of the same provincial administrative division as the full name of the target address when performing road name matching. In making a match, the result should be that there is a matching road name, or there is no matching road name. In the case where there is a matching road name, it may be distinguished that there is only one matching road name, or that there are two or more matching road names.
The splitting module 315 may split according to the matching result. When there is a matching road name, the destination address is divided into a road name, a pre-road-name address, and a post-road-name address. If the matched road does not exist and the target address contains the keyword of the road name, splitting the target address into a pre-road-name address (containing the keyword) and a post-road-name address; and if the matched road does not exist and the target address does not contain the key word of the road name, taking the target address as the address before the road name. If more than two matched road names exist, the two road names and characters between the road names are used as the road names, and the parts are not split. Further, the address before the road name and the address after the road name may be further divided, for example, the address before the road name may be divided into a province name, a city name, a district/county name, a town/street office name, a place/cell name, and the address after the road name may be divided into a house number, a type, a prefix, a sub-number, a suffix, an affiliated facility name, a building number, a floor number, a unit number, a room number, additional information, and the like. Only to what extent the split is, can be determined according to the specific situation of the address, for example, if the room number and the additional information do not exist, the split address does not include the two parts.
In an optional embodiment, the refinement processing device may also include one or more of the indoor map module 325, the processing module 330, the address prompt module 335, the navigation detection module 340.
