As shown in fig. 4, all the points of interest POI obtained in the target rectangular area are represented by a hexagon 402a, and then the distance between each POI and the coordinate point 404a is calculated.

And S308, determining a target POI set according to a comparison result between the distance and a preset search distance.

Specifically, for example, the method includes, but is not limited to, determining POIs corresponding to the distance being smaller than or equal to the preset length as the target POI set.

Here, the set of target POIs is determined, including but not limited to, by the search radius pointed by the user, i.e., all POIs within the search circle area 404 are searched.

In the embodiment of the invention, the current geographic position information of a user is determined, and the geographic position information comprises coordinate points of the user in a target map; acquiring a circular region which takes the coordinate point as a circle center and takes a preset length as a radius, and determining a target rectangular region comprising a preset area of the circular region; acquiring all POIs (points of interest) in the target rectangular area, and respectively determining the distance between each POI and the coordinate point; in the method, because the position of the user is taken as the center of a circle, a circular area with preset length as the radius is used, and a point of interest (POI) in a rectangular area comprising the circular area is searched, the distance between the current position of the user and all POI is not required to be compared; the method and the device greatly reduce the POI searching range, improve the POI searching efficiency and response time, reduce system computing resources, and further solve the technical problems of large calculation amount and long response time of the position information of the determined interest point in the related technology.

In one or more embodiments, the determining the current geographic location information of the user includes:

acquiring current longitude and latitude data of a user; and determining a coordinate point of a target map associated with the application logged in by the user according to the longitude and latitude data.

Here, the current longitude and latitude information of the user is obtained through the LBS service corresponding to the user terminal, but not limited thereto.

determining a rectangular set in a preset range including the circular area according to the longitude and latitude data of the circular area;

determining a target rectangle set inscribed with the circular area from the rectangle set;

and determining the region where the target rectangle set is located as the target rectangle region.

Specifically, a target rectangle set inscribed in the circular region is determined from the rectangle sets, for example, a rectangular region 502 including a circular region 504 in the target rectangle set is determined. And determining the region where the target rectangle set is located as the target rectangle region, so that the search error is avoided, the search range can be further narrowed, and the calculation amount of a server is reduced.

In one or more embodiments, the determining a target rectangle aggregation from the rectangle set that is inscribed in the circular region comprises:

The area where the square area 602 is located is determined as the target rectangular area, so that the search error is avoided, the search range can be further narrowed, and the calculation amount of a server is reduced.

In one or more embodiments, the determining a target rectangular region including the circular region comprises:

determining the position of the POI outside the circle outside the circular area;

determining a set of rectangular areas including a preset number of the out-of-circle POIs as the target rectangular area.

For example, as shown in fig. 4, a hexagon 402 is an out-of-circle POI outside a circular region 404, and it is assumed that when the preset number is 8, it can be determined that the current rectangular region 402 is the target rectangular region or one of the target rectangular regions.

respectively determining the position information of each POI;

and respectively determining the distance between each POI and the coordinate point by using a distance algorithm according to the position information of each POI.

Specifically, according to the standard algorithm GEO-HASH for calculating the positions of two points in the geographic position, an arc distance is formed between the two points instead of a straight line, but the distance from the geographic position of the world to a city may be reduced to a point, and the distance between the two points can be regarded as a plane, and then the distance between two coordinate points which become the plane is calculated. In the embodiment of the present invention, according to the position information of each POI, a GEO-HASH distance algorithm may be used to determine a distance between each POI and the coordinate point.

In one or more embodiments, the point of interest geographic information search further comprises: acquiring recommended interest points matched with the user according to a preset interest point screening model; and displaying the recommended interest points in the application logged in by the user.

Specifically, the interest point screening module includes, but is not limited to, analyzing interest and hobbies of the user through big data and historically accessing interest points to obtain recommended interest points matched with the user.

In the related art, with the development of smart phones and sensor technologies, LBS (Location based service) applications are gradually increasing. Most software relates to position information service, and most companies can more or less use the functions of analyzing and recommending data based on the current geographic position coordinates of users and guiding surrounding resources to promote business development in the business development process.

There are many APPs currently on the market that have their own LBS-based services, but there are also many limitations and problems:

(1) And (4) openness. The service algorithm of the LBS generally does not go to the outside, and is only a Demo version in time to the outside, and cannot be directly used in the service of the LBS.

(2) And (4) service aggregation. Pure geographic location services are relatively independent from algorithms, and generally can play a role only by being deeply integrated into business scene aggregation, and the business uniqueness generates a natural service barrier and cannot be directly used.

(3) Performance and accuracy. The performance requirements and accuracy of final recommendation, data analysis and the like are basic requirements of business so as to achieve popularization of commercial functions.

In order to solve the above technical problem, in an application embodiment, the above method for searching geographic information of a point of interest as shown in fig. 5 further includes the following steps:

1. it is assumed that there is a large amount of POI (e.g., gas station) basic information data on the currently applied service, and each gas station information contains longitude and latitude information.

2. Gas stations within a fixed distance range of the perimeter are obtained based on the user's current location (longitude, latitude) and sorted by distance from near to far.

2.1, calculating a rectangular range of a latitude and longitude range by using a general spatial tool kit based on the current coordinate point (user longitude and user latitude) and the radius (such as the distance of 20 km), and obtaining four vertexes (including a max longitude point, a min longitude point, a max latitude point and a min latitude point) of the rectangular range.

(2) Based on the four longitude and latitude range points, the longitude and latitude points of the gas station stored in the data can be directly matched for query and matching, and the range-reduced points are obtained. The hexagon 402a as shown in fig. 4 represents the above-mentioned gasoline station. According to the standard algorithm GEO-HASH calculated by two points of geographic positions, an arc-shaped distance is formed between the two points instead of a straight line, but the distance between the two points can be reduced into one point from the geographic position of the whole world to a city, the distance between the two points can be regarded as a plane, and then the distance between the two coordinate points which become the plane is calculated. In the embodiment of the present invention, according to the position information of each POI, the distance between each POI and the coordinate point may be determined by using a GEO-HASH distance algorithm.

According to the actual calculation result of the standard GEO-HASH algorithm and the simplified algorithm, the error of the same city is between centimeters and decimeters, and the influence on the applied service is not influenced.

According to the embodiment of the invention, through the simplified distance calculation formula, the actual accurate distance can be calculated at a high speed in the memory of the server or the terminal and the CPU, POI exceeding the radius length are excluded, and the accurate POI set is finally screened out.

3. Precision matching

The above steps can obtain the coordinates of the peripheral oil stations in a fuzzy manner, and further accurately calculate whether the distance between each oil station and the user point is within the radius distance.

The embodiment of the invention also has the following beneficial technical effects:

1. the method has the advantages that the accurate complex calculation model of the standard two-point distance is fully simplified, and the POI is accurately positioned by fully using the combination of specific scenes around the current position of the user.

2. The simplification of the calculation model greatly reduces the consumption of the calculation capacity of the server, and greatly improves the POI search service throughput and the response time.

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.
