In the embodiment of the present invention, the geographic location interest points may include accommodation interest points, traffic interest points, restaurant interest points, and the like. If zhao tao is a technical support staff of a certain company which is frequently on business trip, the online hotel reservation APP is used for reserving the chain hotel A _1 in advance every business trip, the geographical position of the chain hotel A _1 is the interest point of the lodging, and further, if the restaurant accessories of the chain hotel A _1 are in a state that zhao likes going to restaurants such as sha county snacks and Lanzhou pulled noodles for eating, the geographical positions of the sha county snacks and the Lanzhou pulled noodles constitute the interest point of the restaurant and the like.
The original geographic location set comprises a plurality of data groups consisting of geographic location tags and geographic locations corresponding to the geographic location tags. Furthermore, the geographical position positioning equipment comprises an aerial photography system, a satellite shooting system, an airborne remote sensing system, a three-dimensional laser scanning satellite positioning system and the like, different geographical position sets are obtained through the geographical position positioning equipment, then the geographical position range of the frequent activities of the user is obtained through accessing the user terminal, such as a mobile phone, a tablet and other related tourism, a trip APP and the like, and the original geographical position set is obtained through screening from the geographical position set according to the geographical position range of the frequent activities of the user. Such as the geographic locations of hotels [ Hotel A _1, Hotel A _2, Hotel A _3 … ], [ Hotel A _1, Hotel A _2, Hotel A _3 … ], restaurants [ restaurant B _2_1, restaurant B _2, restaurant B _3 … ], restaurant B _2_1, restaurant B _2, restaurant B _3 … ], department store [ mall C _1, mall C _2, mall C _3 … ], department store [ C _1, mall C _2, mall C _3 … ], and the like. In the embodiment of the present invention, the geographic location refers to longitude and latitude, for example, the geographic location of hotel a _1 is east longitude and 32 ° north latitude 47 °.
When the geographic locations in the original geographic location set are judged to belong to different administrative regions according to the longitude and latitude of the original geographic location set, such as city a1 and city b1, the embodiment of the present invention can divide the original geographic location set into city a1_ hotel [ hotel a _1, hotel a _2, hotel a _3 … ] with city a1 as a label, and city b1 is city b1_ hotel [ hotel a _1, hotel a _2, hotel a _3 … ] with labels through the administrative regions.

S2, pre-constructing a multi-dimensional coordinate system, and mapping the standard geographic position set and the geographic position interest points to the multi-dimensional coordinate system to obtain a geographic position coordinate set and geographic position interest point coordinates.
The existing geographic position data matching generally adopts longitude and latitude to calculate the earth spherical distance or calculate the three-dimensional coordinate linear distance, and both methods can achieve the calculation effect, but because the calculation of the longitude and latitude consumes the calculation memory, the calculation of the three-dimensional coordinate linear distance is not accurate enough, and the three-dimensional coordinate is converted from the spherical coordinate, and the conversion of the spherical coordinate into the three-dimensional coordinate consumes a large amount of the memory, thereby being not beneficial to the data matching of the geographic position.
The embodiment of the invention obtains the geographic position coordinate set and the coordinates of the geographic position interest points by constructing the spherical coordinate system. The spherical coordinate system is a way of representing a point in three-dimensional space, where a point is represented by three values, two of which are angles and the third value is a distance, where two angle values determine the direction of the point and a distance value determines the size of the point. For example, the city a1_ Hotel [ Hotel A _1_ first rectangular box, Hotel A _2_ second rectangular box, Hotel A _3_ third rectangular box …]In hotel a _1_ first rectangular box is regarded as point P, and the spherical coordinate representation of point P includes two angles and a distance, which may be specifically
Where r is the distance between the origin O of the spherical coordinate and the point P, theta is the included angle between the directed line segment OP and the positive direction of the z-axis,
Is the angle from the x-axis in the counter-clockwise direction to the OP as viewed from the positive z-axis.
S3, solving the diagonal distance between each geographic position coordinate in the geographic position coordinate set and the geographic position interest point coordinate to obtain a diagonal distance set.
In detail, the S3 includes: respectively solving the longitude distance and the latitude distance of each geographic position coordinate and the geographic position interest point coordinate in the geographic position coordinate set according to a preset geographic longitude and latitude vertical relation, solving the diagonal distance in the plane range according to the longitude distance and the latitude distance, and collecting the diagonal distance to obtain the diagonal distance set.
Preferably, the embodiment of the present invention adopts the following calculation method to solve the longitude distance and the latitude distance of each geographic position coordinate and the geographic position interest point coordinate in the geographic position coordinate set:
d1＝|x1-x2|
d2＝|y1-y2|
wherein d is1Is the distance of the warp threads, x1Is the meridian coordinate value, x, of the geographic position coordinate2A meridian coordinate value, d, of the geographic location point of interest coordinate2Is the weft distance, y1A latitude coordinate value, y, of said geographic position coordinate2And the coordinate value of the latitude line of the geographic position interest point coordinate.
From geographical knowledge, strictly speaking, the longitude and latitude of the earth are not in a vertical relation, and for convenience of calculation, the longitude and latitude of the geography are preset to be in a vertical relation, further, as shown in figure 2, a point A is a geographical position interest point coordinate, a point B is a geographical position coordinate, the longitude distance of the point AB is AM, the latitude distance is BM, and the distance AB is the diagonal distance of the point A and the point B.
According to the Pythagorean theorem, the diagonal distance of AB can be obtained by combining the AM and BM.
And S4, judging whether at least one diagonal distance smaller than a preset threshold exists in the diagonal distance set.
And S5, if the diagonal distance smaller than the preset threshold value does not exist in the diagonal distance set, the geographical location interest point fails to be matched, the result of the failure of the geographical location interest point matching is sent to the geographical location positioning equipment, and the step S1 is returned to obtain the geographical location interest point again.
In the diagonal distance set composed of AB, AC, AD, AE, etc., as described above, the minimum diagonal distance is 31m, and the preset threshold is 29m, so that the geo-location interest point and the original geo-location set cannot be reasonably matched, and thus the matching fails.
S6, if the diagonal distance smaller than the preset threshold exists in the diagonal distance set, selecting the minimum diagonal distance from the diagonal distance set, obtaining the original geographic position corresponding to the minimum diagonal distance, obtaining the geographic position matched with the geographic position interest point, and sending the geographic position matched with the geographic position interest point to the geographic position positioning equipment.
As described above, in the diagonal distance set composed of AB, AC, AD, AE, etc., the minimum diagonal distance is 31mm, the preset threshold value is 32mm, the geographic location coordinate corresponding to the minimum diagonal distance is C point, and the original geographic location corresponding to C point in the original geographic location set obtained by C point query is matched with the geographic location interest point.
Hotels in the city a1 hotel [ hotel a _1_ first rectangular box, hotel a _2_ second rectangular box, hotel a _3_ third rectangular box … ], and in the city b1_ hotel [ hotel a _1_ fourth rectangular box, hotel a _2_ fifth rectangular box, and hotel a _3_ sixth rectangular box … ] labeled as a1 described above, map hotels in the city a1 and hotels in the city b1 in the same coordinate system, and select hotels in the cities a1 and b1 matching the geographic location interest point by calculating diagonal distances of the geographic location interest point and the geographic location coordinate in the coordinate system, and in the same way, restaurant interest points are calculated in the hotels described above, thereby obtaining restaurants in the cities a1 and b1 matching the geographic location interest point.

Furthermore, the geographical position positioning equipment comprises an aerial photography system, a satellite shooting system, an airborne remote sensing system, a three-dimensional laser scanning satellite positioning system and the like, different geographical position sets are obtained through the geographical position positioning equipment, then the geographical position range of the frequent activities of the user is obtained through accessing the user terminal, such as a mobile phone, a tablet and other related tourism, a trip APP and the like, and the original geographical position set is obtained through screening from the geographical position set according to the geographical position range of the frequent activities of the user. Such as the geographic locations of hotels [ Hotel A _1, Hotel A _2, Hotel A _3 … ], [ Hotel A _1, Hotel A _2, Hotel A _3 … ], restaurants [ restaurant B _2_1, restaurant B _2, restaurant B _3 … ], restaurant B _2_1, restaurant B _2, restaurant B _3 … ], department store [ mall C _1, mall C _2, mall C _3 … ], department store [ C _1, mall C _2, mall C _3 … ], and the like.

The coordinate mapping module 102 pre-constructs a multi-dimensional coordinate system, and maps the standard geographic position set and the geographic position interest point to the multi-dimensional coordinate system to obtain a geographic position coordinate set and a geographic position interest point coordinate.
The existing geographic position data matching generally adopts longitude and latitude to calculate the earth spherical distance or calculate the three-dimensional coordinate linear distance, and both methods can achieve the calculation effect, but because the calculation of the longitude and latitude consumes the calculation memory, the calculation of the three-dimensional coordinate linear distance is not accurate enough, and the three-dimensional coordinate is converted from the spherical coordinate, and the conversion of the spherical coordinate into the three-dimensional coordinate consumes a large amount of the memory, thereby being not beneficial to the data matching of the geographic position.
The embodiment of the invention obtains the geographic position coordinate set and the geographic position by constructing the spherical coordinate systemThe coordinates of the point of interest. The spherical coordinate system is a way of representing a point in three-dimensional space, where a point is represented by three values, two of which are angles and the third value is a distance, where two angle values determine the direction of the point and a distance value determines the size of the point.

As described above, in the diagonal distance set composed of AB, AC, AD, AE, etc., the minimum diagonal distance is 31mm, the preset threshold value is 32mm, the geographic location coordinate corresponding to the minimum diagonal distance is C point, and the original geographic location corresponding to C point in the original geographic location set obtained by C point query is matched with the geographic location interest point.
Hotels in the city a1 hotel [ hotel a _1_ first rectangular box, hotel a _2_ second rectangular box, hotel a _3_ third rectangular box … ], and in the city b1_ hotel [ hotel a _1_ fourth rectangular box, hotel a _2_ fifth rectangular box, and hotel a _3_ sixth rectangular box … ] labeled as a1 described above, map hotels in the city a1 and hotels in the city b1 in the same coordinate system, and select hotels in the cities a1 and b1 matching the geographic location interest point by calculating diagonal distances of the geographic location interest point and the geographic location coordinate in the coordinate system, and in the same way, restaurant interest points are calculated in the hotels described above, thereby obtaining restaurants in the cities a1 and b1 matching the geographic location interest point.
