In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.
It should be understood that although the terms first, second, etc. may be used to describe the weight values in the embodiments of the present invention, the weight values should not be limited to these terms. These terms are only used to distinguish the weight values from each other. For example, the first weight value may also be referred to as a second weight value, and similarly, the second weight value may also be referred to as a first weight value without departing from the scope of the embodiments of the present invention.
The word "if" as used herein may be interpreted as "at … …" or "when … …" or "in response to a determination" or "in response to a detection", depending on the context. Similarly, the phrases "if determined" or "if detected (a stated condition or event)" may be interpreted as "when determined" or "in response to a determination" or "when detected (a stated condition or event)" or "in response to a detection (a stated condition or event)", depending on the context.
The system used in the technical scheme provided by the embodiment of the invention is shown in fig. 1 and mainly comprises a terminal and a server, and the method and the device provided by the embodiment of the invention are realized at the server side.
It is understood that the terminal may include a Personal Computer (PC), a notebook Computer, a mobile phone, or a tablet Computer.
An embodiment of the present invention provides a method for acquiring location information, please refer to fig. 2, which is a schematic flow chart of the method for acquiring location information according to the embodiment of the present invention, and as shown in the figure, the method includes the following steps:
s201, obtaining positioning data aiming at each candidate position information according to M candidate position information and a historical positioning record of the terminal, wherein M is an integer larger than 1.
Specifically, first, the server may obtain a historical positioning record of the terminal for each candidate position information of the M candidate position information according to the historical positioning record of the terminal.
The historical positioning record of the terminal may include the positioning time and the corresponding position information (x, y).
Wherein M is an integer greater than 1.
Wherein, the M candidate position information may be preset. For example, M pieces of candidate location information may be selected by the user from the recommended candidate location information.
The past positioning record of the terminal for the candidate position information refers to a past positioning record in which the position indicated by the included position information is within the range corresponding to the candidate position information.
For example, the shape of the uterus is a rectangle, so the range information of the uterus can be determined by the coordinates (x) of four vertices1，y1)、(x2，y2)、(x3，y3) And (x)4，y4) Obtaining if a terminal has location information (x) contained in a history of location records0，y0) The indicated position is within the range determined by the four coordinates, and the historic location record is considered as the historic location record for the candidate position information "the home palace".
For another example, for a certain candidate position information, a historical positioning record containing position information with a distance less than or equal to 500 meters from the candidate position information may be obtained.
For another example, for a certain candidate location information, the range information of the street where the candidate location information is located may be used as the range information of the candidate location information.
Then, the server obtains a historical positioning record of the terminal aiming at each candidate position information in at least one preset time period.
Wherein the time period may include yearly, quarterly, monthly, daily, or hourly, etc.
For example, in units of each day, historical location records for the ith candidate location information of the M candidate location information at each day in the latest period of time may be obtained.
As another example, a historical position fix record is obtained for each candidate location information for each time period within a recent period of time. If the time period includes 0 point to 6 points, 6 points to 11 points, 11 points to 14 points, 14 points to 18 points, and 18 points to 24 points, the historical positioning record of the ith candidate position information in the M candidate position information in the latest time period in each time period is obtained.
It should be noted that the preset time period may be dynamically adjusted according to the type of the point of interest. For example, for a breakfast type of point of interest, a positioning history for each candidate location information within the morning hours needs to be obtained; for another example, for a bar type point of interest, a positioning history for each candidate location information in the evening and morning hours needs to be obtained. As another example, for a scenic spot type of interest, a location history for each candidate location information needs to be obtained for each quarter.
Optionally, since the data volume of the historical positioning record of the terminal is very large, in order to quickly obtain the required data, a spatial index may be established according to the time dimension and the historical positioning record of the terminal, so as to obtain the positioning historical record of the terminal corresponding to each time period. Therefore, when the historical positioning records of the terminal aiming at the candidate position information need to be obtained, the historical positioning records of the terminal aiming at the candidate position information can be obtained by searching in the spatial index according to the preset time period, so that the historical positioning records of all the terminals corresponding to the time period can be obtained, and then the historical positioning records of the terminal aiming at the candidate position information can be obtained from the historical positioning records of all the terminals corresponding to the time period according to the candidate position information. Therefore, it can be seen that the search time of the historical positioning record of the terminal for the candidate position information can be reduced by establishing the spatial index, and the search efficiency is improved.
Finally, the server may obtain, in each time period, the number of times of positioning for each candidate location information according to the historical positioning record of the terminal for each candidate location information in the at least one time period, and use the number of times of positioning as the positioning data.
S202, obtaining the heat information of each candidate position information according to the positioning data aiming at each candidate position information.
Specifically, after obtaining the number of times of positioning for each candidate location information in each time period, the server may obtain an average value of the number of times of positioning for each candidate location information according to a historical positioning record of the terminal for each candidate location information in at least one time period. Then, the server obtains the heat information of each candidate position information according to the average value of the positioning times of each candidate position information.
For example, the average value of the number of times of positioning for a certain candidate position information is obtained by accumulating the number of times of positioning for the candidate position information in each time period of 0 to 6 points, 6 to 11 points, 11 to 14 points, 14 to 18 points, and 18 to 24 points, and dividing the obtained accumulated value by 5.
For another example, the number of times of positioning for a certain candidate position information in the last 30 days is accumulated, and the obtained accumulated sum is divided by 30 to obtain an average value of the number of times of positioning for the candidate position information.
For example, the method for obtaining the heat information of each candidate position information by the server according to the average value of the positioning times for each candidate position information may include:
the heat information of each of the candidate location information may be obtained using the following formula:
wherein HiAnd the heat information represents the ith candidate position information, and the value of i is an integer from 1 to M.
Wherein,Vian average value representing the number of times of positioning with respect to the i-th candidate position information.
Wherein, VminThe minimum value representing the average value obtained from the average value of the number of times of positioning for each of the pieces of candidate position information, that is, the average value of the number of times of positioning for each of the pieces of candidate position information is obtained for each of the M pieces of candidate position information, so that the minimum value of the average values thereof can be obtained by comparing the magnitudes of the average values.
Wherein, VmaxThe maximum value representing the average value obtained from the average value of the number of times of positioning for each of the candidate position information, that is, the average value of the number of times of positioning for each of the M candidate position information is obtained for each of the candidate position information, so that the maximum value of the average value thereof can be obtained by comparing the magnitudes of the average values.
for example, if the heat information of the candidate position information needs to be within a range of 0 to 100, the normalization coefficient β may be equal to 100, for example, if the heat information of the candidate position information needs to be within a range of 0 to 1000, the normalization coefficient β may be equal to 1000, for example, the normalization coefficient β may also be equal to 1.
It can be understood that, according to the above formula, it can be known that the more the number of times of positioning the candidate position information is, the greater the popularity information of the candidate position information is, the greater the traffic volume of people representing the geographical position indicated by the candidate position information is, and it is better to set an interest point at the geographical position indicated by the candidate position information.
S203, selecting N candidate position information from the M candidate position information as target position information according to the heat information of each candidate position information, wherein the target position information is used for determining the set position of the interest point, and N is a positive integer less than or equal to M.
Specifically, for example, the method for the server to select N pieces of candidate location information from the M pieces of candidate location information according to the popularity information of each piece of candidate location information, so as to serve as the target location information, may include the following four methods:
the first method comprises the following steps: the server sorts the M candidate position information according to the heat information of each candidate position information in the M candidate position information and the sequence of the heat information from big to small to obtain a sorting result, then obtains N candidate position information with the top rank in the sorting result, and takes the N candidate position information as the target position information.
And the second method comprises the following steps: the server compares the heat degree information of each candidate position information with a heat degree threshold value according to the heat degree information of each candidate position information and a preset heat degree threshold value, so that N candidate position information of which the heat degree information is greater than or equal to the heat degree threshold value in the M candidate position information can be obtained, and the N candidate position information is used as target position information.
And the third is that: and the server obtains a second weight value of each candidate position information according to the heat information of each candidate position information and a preset first weight value of each candidate position information.
For example, the server may calculate the second weight value for each candidate location information using the following formula:
Wi＝Hi×α+wi×γ
wherein, WiA second weight value representing the ith candidate position information; hiHeat information indicating the ith candidate position information; w is aia first weight value representing the ith candidate position information, a is a preset first weight adjusting factor, and gamma is a preset second weight valueAnd adjusting the weight factor.
Then, the server sorts the M pieces of candidate position information according to the sequence of the second weight values from large to small so as to obtain a sorting result; and the server obtains N pieces of candidate position information ranked at the top in the sorting result, and takes the N pieces of candidate position information as target position information.
And fourthly: and the server obtains a second weight value of each candidate position information according to the heat information of each candidate position information and a preset first weight value of each candidate position information. Then, the server compares the second weight value of each candidate position information with a weight threshold value according to the second weight value of each candidate position information and a preset weight threshold value, so as to obtain N candidate position information of which the second weight value is greater than or equal to the weight threshold value in the M candidate position information, and the N candidate position information is used as target position information.
Wherein N is a positive integer less than or equal to M.
After obtaining the target position information, the server may provide the target position information to the user through the terminal, so as to be used for determining the setup position of the interest point according to the target position information provided by the server. The technical scheme provided by the embodiment of the invention can be suitable for position selection scenes of various interest points, such as position selection of merchants, position selection of basic settings, position selection of newly-built roads, position selection of base stations or position selection of wireless hotspots and the like.
