Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
An embodiment of the present invention provides a method for supplementing a POI address, as shown in fig. 1, the method mainly includes:
101. and acquiring a reference address in a preset geographical area around the POI of the address to be supplemented.
Specifically, the geographic area is determined according to coordinates of the POI of the address to be supplemented, and the coordinates may be longitude and latitude coordinates. The shape of the geographical area is not particularly limited as long as the geographical area is a peripheral area of the POI to be supplemented with the address. The geographic area may or may not cover the coordinates of the POI of the address to be supplemented. Illustratively, the geographic area is a circular geographic area, and the circular geographic area is a circular area with a set radius (e.g., 200 meters) centered on the coordinates of the POI of the address to be supplemented.
The reference address is obtained by referring to the geographic elements covered in the geographic area, that is, the reference address is obtained by referring to the existing data in the geographic area, so that the obtained reference address can accurately reflect the position of the POI of the address to be supplemented.
102. And performing address supplement on the POI of the address to be supplemented based on the reference address.
Specifically, when address supplementation is performed on the POI of the address to be supplemented based on the reference address, the reference address is added to the POI data corresponding to the POI of the address to be supplemented. When the user uses the electronic map, the user can clearly know the address of the POI of the address to be supplemented, and the user can conveniently use the electronic map in application scenes such as route planning, destination inquiring, position inquiring and the like.
According to the method and the device for supplementing the POI address, the reference address in the preset geographic area around the POI of the address to be supplemented is obtained, and the POI of the address to be supplemented is supplemented by the reference address. The address supplement of the POI without the address in the electronic map data is realized, so that the electronic map data is perfected, and the user experience of using the electronic map in application scenes such as route planning, destination inquiry, position inquiry and the like of a user is improved.
Further, according to the method shown in fig. 1, another embodiment of the present invention further provides a method for supplementing a POI address, as shown in fig. 2, the method mainly includes:
201. detecting whether a geographical element with an address and/or a name exists in a preset geographical area around the POI of the address to be supplemented; if so, execute 202; otherwise, 204 is performed.
In particular, the specific category of the geographic element having an address and/or name may be determined according to business requirements. Alternatively, the geographic elements having addresses and/or names may include, but are not limited to, intersections of roads, POIs having addresses and/or names, roads, and natural landscapes. The POI having an address and/or a name may include, but is not limited to, a POI having a house number, a POI having a preset character in the name, a POI having an address, and a POI having a preset character in the name and an address. Natural landscapes may include, but are not limited to, mountains, rivers, lakes, grasses, forests, or forests.
Specifically, the process of detecting whether a geographic element having an address and/or a name exists in a preset geographic area around the POI of the address to be supplemented is related to the number of categories of the geographic element, so that the process includes at least the following two types:
firstly, when the types of the geographic elements with addresses and/or names are only one, directly detecting whether the geographic elements of the types exist in a preset geographic area around the POI of the address to be supplemented, and if so, executing 202; otherwise, 204 is performed. For example, the following steps are carried out: when the geographical elements with the addresses and/or names are only road intersections, directly detecting whether the road intersections exist in a preset geographical area around the POI with the addresses to be supplemented, and if so, executing 202; otherwise, 204 is performed.
Second, when the kinds of the geographic elements having addresses and/or names are plural, a1 to A3 are performed: a1, sequentially selecting one geographical element as the current geographical element according to the preset priority sequence of various geographical elements. A2, detecting whether a current geographic element exists in the geographic area; if so, execute 202; otherwise, a3 is executed. A3, judging whether the current geographic element is the last geographic element in the priority sequence, if so, executing 204; otherwise, a next-priority geographical element adjacent to the current geographical element is selected among the plurality of geographical elements as the current geographical element, and a2 is performed. For example, the following steps are carried out: geographic elements having addresses and/or names include intersections and roads, where intersections are prioritized over roads. Firstly, the intersection is taken as a current geographical element, whether the intersection exists in the geographical area is detected, if so, 202 is executed, and whether the road exists in the geographical area is not detected any more. And if no road intersection exists, continuously detecting whether a road exists in the geographic area, if so, executing 202, and if not, executing 204.
The prioritization of the second category of geographic elements involved can be determined according to business requirements. For example, when the category of the geographic element includes intersection, POI having address and/or name, road, and natural landscape, the set order of priority from high to low may be intersection, POI having address and/or name, road, and natural landscape.
In addition, based on the second procedure described above, the following logic may also exist: a2, detecting whether a current geographic element exists in the geographic area; if so, 202 is performed. When the reference address can not be acquired by the geographic data of the current geographic element at 202, A3 is continuously executed to judge whether the current geographic element is the last geographic element in the priority ordering; if the last geographic element is present, 204 is executed; if not, the next-priority geographic element adjacent to the current geographic element is selected as the current geographic element among the multiple geographic elements, and a2 is performed.
It should be added that, when the current geographic element is a POI with an address and/or a name, since there may be a plurality of kinds of POIs with addresses and/or names, the following logic exists in performing the detection whether the current geographic element exists in the geographic area: and B1, sequentially selecting one POI with the address and/or the name as the current POI according to the preset priority ranking of a plurality of POIs with the address and/or the name. B2, detecting whether a current POI exists in the geographic area; if so, execute 202; otherwise, B3 is executed. B3, judging whether the current POI is the last POI in the priority ordering, if so, executing A3 to judge whether the POI with the address and/or the name is the last geographic element in the priority ordering of the multiple geographic elements; otherwise, the next-priority POI adjacent to the current POI is selected among the POIs as the current POI, and B2 is performed. For example, the following steps are carried out: the priority of the POI with address and/or name is in the order from high to low: a POI having a house number, a POI having a preset character in the name and having an address (e.g., a POI of a shopping mall having an address), a POI having a preset character in the name (e.g., a POI of a building, a POI of a hospital), a POI having an address (e.g., a cell). When the current geographic element is a natural landscape, the logic of detecting whether the current geographic element exists in the geographic area is the same as that when the current geographic element is a POI with an address and/or a name, and details are not repeated here.
It should be added that the coverage of the geographic area can be set according to the category of the geographic element, that is, different types of geographic elements may have different geographic areas or the same geographic area. For example, when the geographic element is a road intersection, the geographic area is 200 meters around the POI of the address to be supplemented. As another example, where the geographic element is a POI having an address and/or name, the geographic area is 100 meters around the POI to be supplemented with the address.
202. Judging whether the geographic data of the geographic element can obtain the reference address or not; if so, go to 203; otherwise, 204 is performed.
Step 202 is performed to improve the accuracy with which the reference address reflects the location of the POI of the address to be supplemented.
All the geographic elements with addresses and/or names in the geographic area may be detected in step 201, and the number of the geographic elements may be one or more, so that the number of the acquired geographic data is consistent with the number of the geographic elements. For example, if the geographic element having the address and/or the name is a road intersection, all the road intersections in the geographic area may be detected, and the acquired geographic data of the road intersection is the road intersection data corresponding to each road intersection.
Specifically, the geographic data of the geographic element includes a name of the geographic element and/or an address of the geographic element. The process of determining whether the geographic data of the geographic element can obtain the reference address may be: when the number of the geographic data is one, inquiring whether the name of the geographic element and/or the address of the geographic element included in the geographic data includes illegal characters, if so, judging that the geographic data of the geographic element cannot acquire the reference address, and executing 204, wherein the reference address is acquired by utilizing the geographic data including the illegal characters, so that the probability that the reference address includes the illegal characters is higher, and the reference address cannot clearly show the position of the POI of the address to be supplemented. If not, judging that the geographic data of the geographic element can obtain the reference address, and executing 203, wherein the reference address is obtained by utilizing the geographic data at the moment, and the reference address can accurately represent the position of the POI of the address to be supplemented. When the number of the geographic data is multiple, inquiring whether at least one geographic element name included in the geographic data and/or illegal characters are not included in the address of the geographic element in the multiple geographic data, if so, judging that the geographic data of the geographic element can obtain a reference address, executing 203, and showing that the probability that the position of the POI of the address to be supplemented can be accurately represented by the reference address by utilizing the geographic data to obtain the reference address is higher; if the address does not exist, judging that the geographic data of the geographic element cannot acquire the reference address, and executing 204, wherein the reference address is acquired by utilizing the geographic data containing illegal characters, the probability that the reference address contains the illegal characters is higher, and the probability that the reference address cannot clearly show the position of the POI of the address to be supplemented is also higher.
It should be added that most of the names of the geographic elements and/or the addresses of the geographic elements are extracted from the map acquisition raw data during the electronic map construction, but due to an error of the extraction method or the map acquisition raw data, illegal characters may exist in the names of a small part of the geographic elements and/or the addresses of the geographic elements. The specific pattern of illegal characters is determined according to specific service requirements.
It should be added that the specific content of the geographic data is related to the type of the geographic element, and when the geographic element is a road intersection, the geographic data is intersection data, which may include, but is not limited to, intersection names, intersection coordinates, and names of the various roads forming the intersection. The geographic data is POI data when the geographic element is a POI having an address and/or name, which can include, but is not limited to, POI name, POI address, POI coordinates. The geographic data is road data when the geographic element is a road, which may include, but is not limited to, road name, road strike data. The geographic data is natural landscape data when the geographic data is natural landscape, and the natural landscape data can include, but is not limited to, a natural landscape name, and a region coordinate range of a region covered by the natural landscape.
203. And acquiring the reference address according to the geographic data of the geographic element.
The specific process of acquiring the reference address according to the geographic data of the geographic element is related to the category of the geographic element, so that the specific process of acquiring the reference address according to the geographic data of the geographic element at least includes the following processes:
first, when the geographic element with the address and/or the name is a road intersection and the geographic data of the road intersection is intersection data, the step 203 of obtaining the reference address according to the geographic data of the geographic element may include:
determining a target road intersection according to the road intersection data;
determining the position of the POI of the address to be supplemented relative to the target road intersection and determining the distance between the target road intersection and the POI of the address to be supplemented based on the road intersection data;
and obtaining the reference address according to the distance, the direction and the name of the target road intersection included in the road intersection data.
Specifically, the process of determining the target road intersection according to the road intersection data is as follows: and when the data of the road intersection is the data of one road intersection, directly determining the road intersection as the target road intersection. And when the road intersection data is the data of a plurality of road intersections, selecting the road intersection with the shortest distance to the POI of the address to be supplemented as the target road intersection. And when the number of the road intersections with the shortest distance to the POI of the address to be supplemented is multiple, randomly selecting the road intersection from the multiple road intersections or selecting a relatively known road intersection as the target road intersection. In addition, in order to avoid confusion in subsequent development of the electronic map, 204 may be directly executed when the number of intersections having the shortest distance to the POI to be supplemented is a plurality of intersections.
Specifically, the process of determining the distance between the target intersection and the POI of the address to be supplemented may include: and converting the longitude and latitude coordinates of the target road intersection into coordinates in a plane coordinate system, and converting the coordinates of the POI of the address to be supplemented into the coordinates of the plane coordinate system. And then determining the distance between the target road intersection and the POI of the address to be supplemented by using a distance formula between two points.
Specifically, the method for determining the position of the POI of the address to be supplemented relative to the target intersection based on the intersection data includes at least the following two methods:
a first method for determining a position of a POI to be supplemented with respect to a target intersection based on the intersection data may include:
setting at least four areas by taking the coordinates of the target road intersection included in the road intersection data as an origin of coordinates; different regions correspond to different orientations;
and determining the position corresponding to the area of the POI covering the address to be supplemented as the position of the POI of the address to be supplemented relative to the target intersection.
Specifically, examples are as follows: as shown in fig. 3 (fig. 3 is only for the purpose of intuitively explaining the determination of the azimuth, and this drawing may not be needed in the actual execution process of determining the azimuth), 8 areas are set with the coordinate a of the target intersection as the coordinate origin, where the azimuth corresponding to the area 301 is north, the azimuth corresponding to the area 302 is north east, the azimuth corresponding to the area 303 is east, the azimuth corresponding to the area 304 is south-east, the azimuth corresponding to the area 305 is south, the azimuth corresponding to the area 306 is south-west, the azimuth corresponding to the area 307 is west, and the azimuth corresponding to the area 308 is north-west. Each area has a respective coordinate range, and different areas have different coordinate ranges. In addition, as can be seen from fig. 3, if the area covering the coordinate B of the POI of the address to be supplemented is the area 301, the position "north" corresponding to the area 301 is determined as the position of the POI of the address to be supplemented relative to the target intersection.
It should be noted that, the method is simple and convenient to determine the orientation, and does not require a large amount of calculation, so that the efficiency of determining the orientation is high.
A second method for determining a position of the POI to be supplemented with respect to the target intersection based on the intersection data may include:
calculating a target angle between the target road intersection and the POI of the address to be supplemented through an inverse trigonometric function;
selecting a target angle interval including the target angle from at least four preset angle intervals; different angle intervals correspond to different directions;
and determining the position corresponding to the target angle interval as the position of the POI of the address to be supplemented relative to the target road intersection.
Specifically, the number of angle sections and the angle range corresponding to each angle section may be preset, and it should be noted that different angle sections correspond to different angle ranges and orientations.
Specifically, the specific type of the inverse trigonometric function may be determined according to the service requirement, for example, the inverse trigonometric function may be any one of an inverse tangent trigonometric function, an inverse cotangent trigonometric function, an inverse sine trigonometric function, and an inverse cosine trigonometric function. The following description will be given taking an inverse trigonometric function as an inverse tangent trigonometric function as an example: and converting the longitude and latitude coordinates of the target road intersection into coordinates in a plane coordinate system, and converting the coordinates of the POI of the address to be supplemented into the coordinates of the plane coordinate system. And (3) calculating a target angle between the target road intersection and the POI of the address to be supplemented according to a formula (1).
The method comprises the steps of β representing a target angle between a target road intersection and a POI of an address to be supplemented, Y1 representing a Y-axis coordinate of the target road intersection in a plane coordinate system, X1 representing an X-axis coordinate of the target road intersection in the plane coordinate system, Y2 representing a Y-axis coordinate of the POI of the address to be supplemented in the plane coordinate system, and X2 representing an X-axis coordinate of the POI of the address to be supplemented in the plane coordinate system.
After a target angle between the target road intersection and the POI of the address to be supplemented is determined, determining the position corresponding to the interval covering the target angle as the position of the POI of the address to be supplemented relative to the target road intersection.
Secondly, when the geographic element with an address and/or a name is a POI with an address and/or a name, and the geographic data of the POI with an address and/or a name is POI data, the step 203 of obtaining the reference address according to the geographic data of the geographic element may include:
determining a target POI according to the POI data;
determining a name and/or address of the target POI based on the POI data;
and obtaining the reference address according to the name and/or address of the target POI.
It should be noted that the type of POI having an address and/or name may be determined according to the service requirement. Alternatively, the POI having an address and/or a name may include, but is not limited to, any one of a POI having a house number, a POI having a preset character in the name, a POI having an address, and a POI having a preset character in the name and an address. For example, the following steps are carried out: the preset characters in the POI having preset characters may include, but are not limited to, buildings, hotels, hospitals, schools, shopping centers, shopping squares.
Specifically, the method for determining a target POI according to the POI data may include: and when the POI data is the data of one POI, directly determining the POI as the target POI. And when the POI data is data of a plurality of POIs, selecting the POI with the shortest distance to the POI of the address to be supplemented as a target POI. And when the number of POIs with the shortest distance to the POI of the address to be supplemented is multiple, selecting the POI randomly from the multiple POIs or selecting the POI with a relatively known name or selecting the POI with the highest type priority as the target POI. The method for selecting the known POI can be as follows: the POI most searched in the map system is a relatively well-known POI. The method for selecting the POI with the highest type priority comprises the following steps: and respectively setting different priorities for each type of POI, and selecting the POI with the highest priority as the target POI when the types of the POI are different.
Specifically, the method for obtaining the reference address according to the name and/or address of the target POI at least includes the following two methods:
the first method for obtaining the reference address is to nest the name and/or address of the target POI into a set address format to obtain the reference address. It should be noted that the address format can be determined according to the service requirement. The address format set may be "POI name + vicinity", or the address format set may be "POI address + POI name + vicinity".
According to the second method for obtaining the reference address, the position of the POI of the address to be supplemented relative to the target POI is determined according to the coordinates of the target POI and the coordinates of the POI of the address to be supplemented. And then, nesting the name and/or address and direction of the target POI into a set address format to obtain a reference address. It should be noted that the address format can be determined according to the service requirement. The address format set may be "POI name + position + vicinity", or the address format set may be "POI address + position + vicinity". For example, the following steps are carried out: the adopted address format is ' POI address + POI name + azimuth + vicinity ', the target POI name is ' Fangheng International centre seat A ', the address is ' Futongdong east Avenue 6 ', the azimuth is ' southeast ', and the obtained reference address is ' Futongdong east Avenue 6 Fangheng International centre seat A ' vicinity to the southeast side '. In addition, it should be added that the method for determining the position in this method is the same as the above-mentioned method for determining the position of the POI to be supplemented with the address relative to the target intersection based on the intersection data, and will not be described herein again.
And in the third method for obtaining the reference address, the distance between the target POI and the POI of the address to be supplemented is determined according to the coordinates of the target POI and the coordinates of the POI of the address to be supplemented. And determining the position of the POI of the address to be supplemented relative to the target POI according to the coordinates of the target POI and the coordinates of the POI of the address to be supplemented. And then nesting the name and/or address, direction and distance of the target POI into a set address format to obtain a reference address. It should be noted that the address format can be determined according to the service requirement. The address format set may be "POI name + position + distance + vicinity", or the address format set may be "POI address + position + distance + vicinity". For example, the following steps are carried out: the adopted address format is 'POI address + POI name + azimuth + distance + vicinity', the target POI name is 'Fangheng International centre A seat', the address is 'Futongdong Dong Dajie No. 6', the azimuth is 'southeast', and the distance is '50 meters', then the obtained reference address is 'Futongdong Dong Dajie No. 6 Fangheng International centre A seat is near southeast 50 meters'. In addition, it should be added that the method for determining the position in this method is the same as the above-mentioned method for determining the position of the POI to be supplemented with the address relative to the target intersection based on the intersection data, and will not be described herein again.

determining a target road according to the road data;
and obtaining the reference address according to the name of the target road included in the road data.
Specifically, the method for determining the target road according to the road data may include: when the road data is data of one road, the road is directly determined as the target road. And when the road data is data of a plurality of roads, selecting the road with the shortest distance to the POI of the address to be supplemented as the target road. And when the number of the roads with the shortest distance to the POI of the address to be supplemented is multiple, randomly selecting or selecting a relatively known road from the multiple roads as a target road. The selection method of the well-known road can be as follows: the road that is searched the most frequently in the map system is the more well-known road.
Specifically, the method for obtaining the reference address according to the name of the target road included in the road data may include: and nesting the name of the target road into a set address format to obtain a reference address. It should be added that the address format can be determined according to the service requirement. For example, the following steps are carried out: the set address format is 'road name + vicinity', the road name is Futongdong avenue, and the determined reference address is 'Futongdong avenue vicinity'.
Fourthly, the geographic elements with addresses and/or names are natural landscapes, and the geographic data of the natural landscapes are natural landscape data; obtaining the reference address according to the geographic data of the geographic element, including:
determining a target natural landscape according to the natural landscape data;
determining the position of the POI of the address to be supplemented relative to the target natural landscape based on the natural landscape data;
and obtaining the reference address according to the direction and the name of the target natural landscape.
Specifically, the type of natural landscape may be determined according to business requirements, and alternatively, the natural landscape may include, but is not limited to, any one of mountains, rivers, lakes, grasslands, forests, or forests.
In one aspect, the process of determining the target nature landscape from the nature landscape data may include, but is not limited to: and when the natural landscape data is data of a natural landscape, directly determining the natural landscape as the target natural landscape. And when the natural landscape data is data of a plurality of natural landscapes, selecting the natural landscape with the shortest distance to the POI of the address to be supplemented as the target natural landscape. And when the number of the natural landscapes with the shortest distance to the POI of the address to be supplemented is multiple, randomly selecting or selecting a more known natural landscape or a natural landscape with the highest type priority from the multiple natural landscapes as the target natural landscape. The selection method of the well-known natural landscape comprises the following steps: the natural landscape searched for the most times in the map system is the more well-known natural landscape. The method for selecting the natural landscape with the highest type priority comprises the following steps: different priorities are set for each type of natural landscapes respectively, and when the types of the natural landscapes are different, the landscape with the highest priority is selected as the target natural landscape.
Specifically, the method for determining the position of the POI to be supplemented with respect to the target natural landscape based on the natural landscape data may include: and acquiring the area coordinate range of the area covered by the target natural landscape from the natural landscape data, and determining at least four sample coordinate ranges according to the area coordinate ranges, wherein the sample coordinate ranges are coordinate ranges around the area coordinate range, and each sample coordinate range corresponds to one direction.
