[ detailed description ] embodiments
In order to make the technical solution of the present invention clearer and more obvious, the solution of the present invention is further described below by referring to the drawings and examples.
It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a flowchart illustrating a method for locating an administrative area according to a first embodiment of the present invention. As shown in fig. 1, the following detailed implementation is included.
In 101, multi-dimensional data information of a user is acquired.
In 102, if the multi-dimensional data information includes the IP information of the user but does not include the longitude and latitude information of the user, the administrative area where the user is located is determined according to the IP information.
In 103, if the multi-dimensional data information includes the IP information of the user and the longitude and latitude information of the user at the same time, the administrative area where the user is located is determined according to the longitude and latitude information.
The obtained various information of the user can be integrated, so that the multi-dimensional data information of the user is obtained.
Generally, the multi-dimensional data information may include IP information of the user, latitude and longitude information of the user, and some other information.
If the multi-dimensional data information contains the IP information of the user but does not contain the longitude and latitude information of the user, the administrative area where the user is located can be determined according to the IP information, and if the multi-dimensional data information contains the IP information of the user and the longitude and latitude information of the user at the same time, the administrative area where the user is located can be determined according to the longitude and latitude information.
When the administrative region where the user is located is determined according to the IP information, the administrative region corresponding to the IP information can be determined by inquiring a pre-generated comparison table of the IP and the administrative region, the determined administrative region is further used as the administrative region where the user is located, and different administrative regions respectively corresponding to the IP information are recorded in the comparison table of the IP and the administrative region.
In the embodiment, a correspondence relationship between the IP segments and the administrative areas is converted into a correspondence relationship between the IP information and the administrative areas, that is, kv pairs of the IP information and the administrative areas are generated, so that a comparison table of the IP and the administrative areas recorded with different IP information respectively corresponding to each other is obtained, and one administrative area may correspond to a plurality of IP information. Therefore, when the administrative region where the user is located is required to be determined according to the IP information of the user, the IP information of the user can be used as a key to search, and the administrative region where the user is located is obtained.
When the administrative area where the user is located is determined according to the longitude and latitude information, the possibly multi-dimensional data information comprises at least two kinds of longitude and latitude information, namely the multi-latitude and longitude information, so that the longitude and latitude information with the highest priority can be selected according to a preset priority sequence, and then the administrative area where the user is located is determined according to the selected longitude and latitude information.
For example, the latitude and longitude information may include Global Positioning System (GPS) data, wifi positioning data, base station positioning data, and latitude and longitude data located by other chips.
The priority order of various latitude and longitude information can be preset, for example, the priority order is from high to low: GPS data, wifi positioning data, base station positioning data and longitude and latitude data positioned by other chips. Therefore, when the multi-dimensional data information contains various latitude and longitude information, the latitude and longitude information with the highest priority can be selected, and the administrative area where the user is located is determined according to the selected latitude and longitude information.
Specifically, an administrative area where the longitude and latitude information is located can be determined by querying a pre-generated administrative area boundary dictionary, the determined administrative area is used as the administrative area where the user is located, and longitude and latitude boundary coordinate sets corresponding to different administrative areas are recorded in the administrative area boundary dictionary.
The longitude and latitude boundary coordinates of all administrative areas in the country can be acquired based on a Baidu map and the like, so that a longitude and latitude boundary coordinate set is respectively formed for each administrative area, and the boundary of the administrative area can be constructed according to the longitude and latitude boundary coordinate set. The administrative region may be a polygonal region containing any number of edges.
Because the administrative region is a polygonal region containing any number of edges, the mathematical problem that whether the query point is in the polygon can be converted by determining the administrative region according to the given longitude and latitude information. Correspondingly, in this embodiment, for each longitude and latitude boundary coordinate set, a ray may be respectively introduced with a coordinate point corresponding to the longitude and latitude information as an endpoint, the number of intersection points of the ray and the side of the polygonal area constructed by the longitude and latitude boundary coordinate set is calculated, if the number of the intersection points is an odd number, the longitude and latitude information is determined to be located inside the polygonal area, and the administrative area corresponding to the polygonal area is determined to be the administrative area where the longitude and latitude information is located.
Namely, an administrative region where longitude and latitude information is located is determined by adopting a ray method. The basic idea of the ray method is as follows: and (3) guiding a ray by taking the target point as an end point, calculating the number of intersection points of the ray and all edges of the polygon, if the number of the intersection points is an odd number, indicating that the target point is positioned inside the polygon, and if the number of the intersection points is an even number, indicating that the target point is positioned outside the polygon.
For example, the following steps are carried out: FIG. 2 is a schematic view of a polygon according to the present invention. The key point of the ray method is unidirectional emission, taking a horizontal line as an example, a target point O is positioned inside a polygon, rays are emitted to the right, intersection points with the polygon are a point B, a point C and a point D, rays are emitted to the left, intersection points with the polygon are an odd number, an intersection point P is positioned outside the polygon, and no matter rays are emitted to the left or the right, 2 intersection points with the polygon are even numbers.
Specifically, in this embodiment, the target point shown in fig. 2 is a coordinate point corresponding to latitude and longitude information of the user, and the polygon shown in fig. 2 is a polygon area constructed by any latitude and longitude boundary coordinate set.
In the above embodiment, when the multi-dimensional data information includes the IP information of the user and the longitude and latitude information of the user at the same time, the administrative area where the user is located is determined according to the longitude and latitude information.
Fig. 3 is a flowchart of a second embodiment of the administrative area locating method according to the present invention. As shown in fig. 3, the following detailed implementation is included.
In 301, multi-dimensional data information of a user is obtained.
In 302, if the multi-dimensional data information includes the IP information of the user and the longitude and latitude information of the user at the same time, the processing is performed in the manner shown in 303-305.
In 303, the administrative region where the user is located is determined according to the IP information.
For example, the administrative region corresponding to the IP information may be determined by querying a pre-generated IP-administrative region comparison table, and the determined administrative region is used as the administrative region where the user is located, and the administrative regions corresponding to different IP information are recorded in the IP-administrative region comparison table.
At 304, the administrative area where the user is located is determined according to the latitude and longitude information.
For example, an administrative area where the longitude and latitude information is located may be determined by querying a pre-generated administrative area boundary dictionary, and the determined administrative area is used as an administrative area where the user is located, and longitude and latitude boundary coordinate sets corresponding to different administrative areas are recorded in the administrative area boundary dictionary.
Specifically, for each longitude and latitude boundary coordinate set, a ray may be respectively introduced with a coordinate point corresponding to the longitude and latitude information as an endpoint, the number of intersection points of the ray and the side of the polygonal area constructed by the longitude and latitude boundary coordinate set is calculated, if the number of the intersection points is an odd number, the longitude and latitude information is determined to be located inside the polygonal area, and the administrative area corresponding to the polygonal area is determined to be the administrative area where the longitude and latitude information is located.
If the multi-dimensional data information contains at least two kinds of longitude and latitude information, the longitude and latitude information with the highest priority can be selected according to a preset priority sequence, and then the administrative region where the user is located is determined according to the selected longitude and latitude information.
In 305, the administrative areas determined twice are compared, if the administrative areas are consistent, the determined administrative area is used as the administrative area where the user is located, and if the administrative areas are not consistent, the administrative area determined according to the longitude and latitude information is used as the administrative area where the user is located.
After the two administrative areas are determined according to the manners shown by 303 and 304, the two administrative areas can be compared, if the two administrative areas are consistent, the determined administrative area can be used as the administrative area where the user is located, and if the two administrative areas are not consistent, the administrative area determined according to the longitude and latitude information can be used as the administrative area where the user is located.
Considering that the administrative region determined based on the longitude and latitude information is more accurate, when the positioning results obtained twice are inconsistent, the more accurate positioning result can be adopted, so that the accuracy of the positioning result is improved, and when the positioning results obtained twice are consistent, the positioning result obtained in 304 is equivalently verified further by using the positioning result obtained in 303, so that the accuracy of the positioning result is ensured.
It should be noted that, for simplicity of description, the above-mentioned method embodiments are described as a series of acts or combination of acts, but those skilled in the art will recognize that the present invention is not limited by the order of acts, as some steps may occur in other orders or concurrently in accordance with the invention. Further, those skilled in the art should also appreciate that the embodiments described in the specification are preferred embodiments and that the acts and modules referred to are not necessarily required by the invention.
In the above embodiments, the descriptions of the respective embodiments have respective emphasis, and for parts that are not described in detail in a certain embodiment, reference may be made to related descriptions of other embodiments.
In a word, by adopting the scheme of the invention, the longitude and latitude information can be utilized to well supplement the existing administrative region positioning, thereby improving the accuracy of the positioning result and the like.
The above is a description of method embodiments, and the embodiments of the present invention are further described below by way of apparatus embodiments.
Fig. 4 is a schematic structural diagram of an embodiment of the administrative area positioning device according to the present invention. As shown in fig. 4, includes: an acquisition unit 401 and a positioning unit 402.
An obtaining unit 401 is configured to obtain multidimensional data information of a user.
The positioning unit 402 is configured to determine an administrative area where the user is located according to the IP information when the multi-dimensional data information includes the IP information of the user but does not include the longitude and latitude information of the user, and determine the administrative area where the user is located according to the longitude and latitude information when the multi-dimensional data information includes the IP information of the user and the longitude and latitude information of the user at the same time.
The obtaining unit 401 may integrate the obtained various information of the user, so as to obtain the multidimensional data information of the user.
Generally, the multi-dimensional data information may include IP information of the user, latitude and longitude information of the user, and some other information.
If the multi-dimensional data information includes the IP information of the user but does not include the longitude and latitude information of the user, the positioning unit 402 may determine the administrative area where the user is located according to the IP information, and if the multi-dimensional data information includes the IP information of the user and the longitude and latitude information of the user at the same time, the positioning unit 402 may determine the administrative area where the user is located according to the longitude and latitude information.
When the administrative area where the user is located is determined according to the IP information, the positioning unit 402 may determine the administrative area corresponding to the IP information by querying a pre-generated IP and administrative area comparison table, and then take the determined administrative area as the administrative area where the user is located, where the administrative areas corresponding to different IP information are recorded in the IP and administrative area comparison table.
When the administrative area where the user is located is determined according to the longitude and latitude information, the multi-dimensional data information may include at least two kinds of longitude and latitude information, that is, multiple kinds of longitude and latitude information, so that the positioning unit 402 may select the longitude and latitude information with the highest priority according to a preset priority order, and then determine the administrative area where the user is located according to the selected longitude and latitude information.
For example, the latitude and longitude information may include GPS data, wifi positioning data, base station positioning data, latitude and longitude data located by other chips, and the like.
The priority order of various latitude and longitude information can be preset, for example, the priority order is from high to low: GPS data, wifi positioning data, base station positioning data and longitude and latitude data positioned by other chips.
Specifically, the positioning unit 402 may determine an administrative area where the longitude and latitude information is located by querying a pre-generated administrative area boundary dictionary, and use the determined administrative area as an administrative area where the user is located, where longitude and latitude boundary coordinate sets respectively corresponding to different administrative areas are recorded in the administrative area boundary dictionary.
The longitude and latitude boundary coordinates of all administrative areas in the country can be acquired based on a Baidu map and the like, so that a longitude and latitude boundary coordinate set is respectively formed for each administrative area, and the boundary of the administrative area can be constructed according to the longitude and latitude boundary coordinate set. The administrative region may be a polygonal region containing any number of edges.
The positioning unit 402 may respectively direct a ray to each longitude and latitude boundary coordinate set by using a coordinate point corresponding to the longitude and latitude information as an endpoint, calculate the number of intersection points of the ray and the side of the polygon area constructed by the longitude and latitude boundary coordinate set, determine that the longitude and latitude information is located inside the polygon area if the number of the intersection points is an odd number, and determine the administrative area corresponding to the polygon area as the administrative area where the longitude and latitude information is located.
Namely, an administrative region where longitude and latitude information is located is determined by adopting a ray method. The basic idea of the ray method is as follows: and (3) guiding a ray by taking the target point as an end point, calculating the number of intersection points of the ray and all edges of the polygon, if the number of the intersection points is an odd number, indicating that the target point is positioned inside the polygon, and if the number of the intersection points is an even number, indicating that the target point is positioned outside the polygon.
In addition, when the multi-dimensional data information simultaneously includes the IP information and the latitude and longitude information, the positioning unit 402 may determine the administrative area where the user is located by combining the IP information and the latitude and longitude information.
For example, the positioning unit 402 may determine the administrative area where the user is located according to the IP information, determine the administrative area where the user is located according to the longitude and latitude information, compare the administrative areas determined twice, if the administrative areas are consistent, use the determined administrative area as the administrative area where the user is located, and if the administrative areas are not consistent, use the administrative area determined according to the longitude and latitude information as the administrative area where the user is located.
