With the development of each service at present, the demand for the scene positioning capability is more and more strong. When the longitude and latitude of the user are obtained, the real scene where the user is located, that is, the building where the user is located, such as a supermarket, a community, a market, a building and the like, needs to be confirmed. In the related technology, indoor and outdoor judgment is continuously carried out by moving Wi-Fi signal receiving equipment, after a user enters a building, the Wi-Fi signal intensity is obtained by detecting signals of wireless routers in the building at different positions, and the distance between the equipment and each wireless router is calculated, so that the longitude and the latitude and the height of each wireless router are calculated. And then performing cluster analysis on the stored position data of all the wireless routers, determining each class as an independent building to be numbered according to the result of the cluster analysis, and storing the characteristics of the buildings. And then, when the user requests, comparing the building characteristics according to the information of the surrounding routers, and finishing the identification of the building.

However, in the related art, in order to complete the identification of the building with the building as a dimension, building features (latitude and longitude, height, and the like of the wireless router) must be manually collected inside the building. Thereby increasing labor costs. Furthermore, the position of the newly added router needs to be estimated by depending on information such as longitude and latitude, Wi-Fi signal strength and the like during indoor positioning, and due to the fact that the indoor satellite positioning result is greatly deviated due to factors such as being shielded by a building and the like, signals of the wireless router are also influenced by the building structure, the router model and the like, and Wi-Fi in actual life may frequently change, such as closing of a shop in a market, newly added shop, moving of Wi-Fi and the like, which can cause the change of the whole Wi-Fi environment, and accordingly inaccurate positioning is caused.

Therefore, how to identify Wi-Fi of a building in a real service scene and accurately position the building by using the Wi-Fi is a technical problem to be solved at present.

In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.

Fig. 1 is a flowchart illustrating a Wi-Fi recognition method based on a service scenario, which is used in a terminal as shown in fig. 1, and according to an exemplary embodiment, includes the following steps:

in step 101, acquiring service requests sent by a plurality of users with the service purpose of the same building, a Wi-Fi list around the time of sending each service request, planar polygon data of the building, and a plurality of pieces of track data responding to the service requests;

in step 102, identifying the identification information of the building where the Wi-Fi in each Wi-Fi list sending the service request is located; processing each piece of track data in the plurality of pieces of track data, and selecting an area with the largest number of key points in each piece of track data as a two-dimensional Gaussian distribution center point;

in step 103, determining a building with the shortest boundary distance from the center point of the two-dimensional Gaussian distribution to the plane polygon data of the building as a target building;

in step 104, the identification information of the building where the Wi-Fi sending the service request is located is bound with the target building, so as to obtain the Wi-Fi of the target building.

The Wi-Fi identification method based on the service scene can be applied to terminals, servers and the like, and is not limited herein, and the terminal implementation equipment can be electronic equipment such as a smart phone, a notebook computer and a tablet computer.

The following describes in detail specific implementation steps of a Wi-Fi identification method based on a service scenario according to an embodiment of the present invention with reference to fig. 1.

First, step 101 is executed to obtain service requests sent by a plurality of users with service purposes in the same building, and a Wi-Fi list around each service request, planar polygon data of the building, and a plurality of pieces of track data responding to the service requests.

In this step, the service purpose is a destination of the service, for example, a building or the like whose delivery destination is the same. That is, it is necessary to obtain service requests sent by a plurality of users having the same delivery destination and a plurality of pieces of trajectory data of a plurality of configurators responding to the service requests, and of course, it is also necessary to obtain a Wi-Fi list around when each service request is sent, and each Wi-Fi list may include one or more Wi-Fi. Specifically, in this step, three types of data need to be acquired, and for convenience of description, the service request in this embodiment is a delivery request, but in practical application, the service request is not limited to this.

The first type of data is data associated with the buyer. Including Wi-Fi listing information around when the buyer initiates the delivery request. Specifically, for example, in a scenario where a user orders take a take-out in building a, the user requests positioning when placing an order, and therefore when a take-out order request initiated by the user is detected in the background, Wi-Fi information around the take-out order request sent by the user can be acquired. It should be noted that the present embodiment generally selects those requests that originate from inside the building.

The second type of data is trajectory data associated with a plurality of dispatchers. That is, each distributor forms a piece of track data in the process of distributing for the buyer, and the track data generally consists of a GPS positioning point and has the attributes of positioning longitude and latitude, precision, speed, time and the like. In this embodiment, a plurality of pieces of trajectory data of the deliverer who delivers goods to the same destination are selected.

The third type of data is data relating to the building in which the buyer is located. The building-related data is two-dimensional plane data of the building on a map, that is, only the fence attribute related to the present invention in the building-related data, but of course, the building-related data may also include a height attribute, and thus the height attribute is not related to the present invention and will not be described herein. The fence attribute refers to boundary information of a building and is a plane polygon formed by longitude and latitude points. In the invention, the acquired building attributes are combined with other information (such as Wi-Fi for initiating a delivery request, trajectory data of a deliverer and the like) and applied to each service scene.

It should be noted that the embodiment of the present invention is based on big data, and a large amount of such data is acquired instead of a delivery request + the data of the trajectory of the deliverer. Specifically, when a plurality of delivery destinations are the same, the destinations are considered to be the same building, and WI-FI mining is performed based on a large amount of trajectory data.

Secondly, step 102 is executed, identification information of a building where the Wi-Fi sending the service request is located in each Wi-Fi list is identified, each piece of track data is processed, and the area with the largest number of key points in each piece of track data is selected as a two-dimensional Gaussian distribution center point.

In this step, the background may identify identification Information (ID) of a building where each Wi-Fi in each Wi-Fi list is located, that is, by monitoring network information of the user, address information of the user according to the network, that is, information of the building where the user is located may be obtained. For example, what street and how many buildings in what area building a is, etc. The specific identification process is well known in the art and will not be described herein.

In this step, each piece of trajectory data in the plurality of pieces of trajectory data is processed, and the region with the largest number of key points in each piece of trajectory data is selected as the two-dimensional gaussian distribution center point, where the specific processing procedure includes:

preprocessing each piece of track data in the plurality of pieces of track data to obtain key point data of the plurality of tracks; and aggregating the key point data of the plurality of tracks, and selecting the area with the largest number of key points as a two-dimensional Gaussian distribution center.

In the embodiment, each of the plurality of pieces of trajectory data is formed using a plurality of continuous positioning points given by GPS satellites. For example, after a distributor enters a building, the satellite information may not be obtained due to the shielding of the building, and thus a positioning result may not be obtained. In addition, when the distributor approaches to the building, the positioning result generally has a large drift due to the multipath effect of the signal, and the confidence of the positioning result is also reduced. As shown in fig. 2, fig. 2 is a schematic diagram of an original trajectory point of a distributor according to an embodiment of the present invention, and as shown in fig. 2, before the distributor enters a certain cell and after the distributor leaves the certain cell, the trajectory of the distributor is relatively smooth and relatively matched with a road network. However, after the dispatcher enters the cell, the positioning points are distributed in a messy way due to the multipath effect and are not already in the track. In the embodiment of the invention, before the data is used, the data corresponding to the original track point is processed, and the purpose of processing is to extract the normal track point adjacent to the abnormal track point.

In this step, the pretreatment process may include:

the background selects track points meeting preset conditions from each piece of track data; then, judging whether each track point is an abnormal track point, if so, extracting a normal track point which is in front of the abnormal track point and adjacent to the abnormal track point; and then deleting the abnormal track points from the track points to obtain normal track points, and taking the normal track points as track key points in the corresponding track data. The track points in the invention are usually GPS positioning points, and the GPS positioning points have the following attributes: positioning longitude and latitude, precision, speed and time. The method specifically comprises the following steps:

1) firstly, selecting track points meeting preset conditions from each piece of track data, wherein the preset conditions at least comprise one of the following conditions, and the precision between two continuous GPS positioning points is smaller than a threshold value g; the distance between the two GPS positioning points is smaller than a threshold value d, the time difference between the two GPS positioning points is smaller than a threshold value t, and the variance between the average speed between the two GPS positioning points and the first n average speeds does not exceed the threshold value. And n is the number of GPS positioning points of each piece of track data. Of course, in practical applications, the method is not limited to this, and other GPS positioning points meeting preset conditions may also be adaptively included. The invention refers to the track formed by the track points as a compliant track. Wherein the compliance trajectory is divided into a forward compliance trajectory and a reverse compliance trajectory. Firstly, determining a forward compliance track, recording the last GPS positioning point p as a candidate key point, and setting a forward counter countp to be 0. The backward compliance trace is set to null and the backward counter countn is 0. Continuing to judge the next GPS positioning point p;

2) and continuously judging whether the next GPS positioning point p meets the preset condition. If the GPS positioning point p meets the preset condition in the step 1), the GPS positioning point p is called as a normal track point, and the step 3) is carried out. If the GPS positioning point p does not meet the preset condition in 1), the GPS positioning point p is called as an abnormal track point, a forward counter is +1, and the current candidate key point is set as a determined key point, and the step 4) is carried out;

3) if the forward counter is smaller than the threshold c1, adding the GPS positioning point p into the forward track, setting the GPS positioning point p as a new candidate key point, setting the current reverse track as empty and the reverse counter as 0, continuously judging the next GPS positioning point p, and entering the step 2); otherwise, entering step 4);

4) calculating a reverse track taking the current next GPS positioning point p as an end point, if a reverse compliance track appears, selecting the end point of the forward compliance track and the start point of the reverse compliance track as a pair of key points of the track, regarding the reverse compliance track as a forward direction, emptying the reverse track and a reverse counter, continuing the next GPS positioning point p, and re-entering the step 2) until the whole track is finished; if a reverse compliance track with p as the key point does not appear, adding p into the reverse track, reversing the counter to +1, judging the next GPS positioning point p again, and entering the step 2);

5) and repeating the process until all the key points are judged.

6) And after the judgment is finished, namely when the whole track is finished, extracting all key points to serve as a subsequent excavation basis. Namely, extracting normal track points which are in front of the abnormal track points and are adjacent to the abnormal track points;

7) deleting the abnormal track points from the track points (namely the original track points) to obtain normal track points; specifically, as shown in fig. 3, a schematic diagram for deleting an abnormal track point from an original track point is provided in the embodiment of the present invention.

8) And taking the normal track points as track key points in corresponding track data. Specifically, as shown in fig. 4, a schematic diagram of a track key point provided in the embodiment of the present invention is shown.

As can be seen from fig. 2, 3 and 4, fig. 2 shows the original trajectory without any processing, and it can be seen that some sharp abnormal trajectory points appear in the middle; FIG. 3 shows the trace after the abnormal trace points are deleted, and it can be seen that the trace is much smoother; the normal track points marked by two circles shown in fig. 4 are found key points of the track.

Performing aggregation processing on the key point data of the plurality of tracks, and selecting an area with the largest number of key points as a two-dimensional Gaussian distribution center point; the method specifically comprises the following steps:

acquiring a geohash block where the longitude and latitude of a track key point of each piece of track data are located; mapping the track key points in each track data to corresponding geohash blocks; counting the number of key points in each geohash; extracting a geohash block where all track key points are located, wherein all the extracted geohash blocks form a two-dimensional rectangular plane; respectively taking two sides of the two-dimensional rectangular plane as an x axis and a y axis, and taking the number of key points in the geohash block as a z axis to establish a three-dimensional coordinate system; determining mixed two-dimensional Gaussian distribution of the number distribution of key points of the fitting track in the three-dimensional coordinate system; determining a central area of a central point of the mixed two-dimensional Gaussian distribution on the two-dimensional rectangular plane; and selecting the two-dimensional Gaussian distribution center point with the maximum number of the track key points in the center area.

That is, in this step, the following method is specifically adopted for aggregating the key points of the trajectory:

1) firstly, a geohash block where the longitude and latitude of a track key point are located is obtained. The geohash block is a general technology for geographically representing a rectangular geographic plane space, and may be represented by a string of characters, as shown in fig. 5, where fig. 5 is a schematic diagram of dividing a map into multiple grids by using a geohash with a length of 9 according to an embodiment of the present invention. Wherein, the geohash block with the character length of 9 is about a square with the side length of 5 meters, the invention selects the example that the geohash with the character length of 9 divides the map into a plurality of grids.

It should be noted that GeoHash is a method for converting two-dimensional longitude and latitude into a character string, and in general, the more the prefix matching of the character string, the closer the distance. As shown in fig. 5, the GeoHash strings of 9 beijing regions, WX4ER, WX4G2, WX4G3, etc., are shown, and each string represents a rectangular region. That is, all points (longitude and latitude coordinates) in the rectangular area share the same GeoHash character string, so that privacy can be protected (only approximate area positions are represented instead of specific points), and caching is easier. Different coding lengths represent different range intervals, and the longer the character string, the more precise the range is represented. The character strings are similar in representation distance, so that the POI information nearby can be inquired by prefix matching of the character strings.

2) And aiming at a plurality of pieces of track data of the same destination, after mapping the track key points in each piece of track data to the geohash block, counting the number of key points in each geohash block.

3) In this case, the two-dimensional planar map may be regarded as a large mesh divided by a plurality of geohash blocks. A part including a geohash block where all track key points are located is intercepted to form a two-dimensional rectangular plane, values of two side lengths of the two-dimensional rectangular plane are respectively taken as an x axis and a y axis, the number of the key points in the geohash block is taken as a value of a z axis, a three-dimensional coordinate system is established, the established three-dimensional coordinate system is shown in fig. 6, and fig. 6 is a schematic diagram for establishing the three-dimensional coordinate system provided by the embodiment of the invention.

4) In the three-dimensional coordinate system, a mixed two-dimensional gaussian distribution fitting the distribution of the number of the key points of the trajectory is found, and an example of the two-dimensional gaussian distribution is shown in fig. 6.

For example, the vertical projection point of the two-dimensional gaussian distribution center point on the xy plane is (x1, y1), and a plane C (x, y) is determined, where the plane C (x, y) satisfies:

and | x-x1| ≦ k and | y-y1| ≦ k.

And selecting a region with the maximum number of the central regions C including the key points of the tracks as a two-dimensional Gaussian distribution central point, namely a target two-dimensional Gaussian distribution central point, in all the two-dimensional Gaussian distributions.

The obtained target two-dimensional gaussian distribution center geohash, plane area C (x, y), is used for the determination of the target building in the following steps.

Thirdly, executing a step 103, and determining the building with the shortest boundary distance from the geohash to the plane polygon data of the building as a target building;

in this step, in step 101, the plane polygon data (which may also be referred to as building data) acquired from the building only includes the fence and height attributes. In step 102, a two-dimensional gaussian distribution center geohash is calculated for a destination building, and in this step, only a building closest to the geohash needs to be determined, that is, the target building.

3) The method is applied to rendering of buildings and points of interest (POI) in map display: when a map is displayed, the following may occur. POI such as "a period of 3 blocks" do not perfectly fit with its corresponding building. When viewed by a user, the user experience is greatly influenced. If after the relationship mining from Wi-Fi to the building is realized, the relationship mining from the POI to the building can be realized by combining with other works such as portrayal from Wi-Fi to the POI, the relationship mining from the POI to the building can be realized by taking Wi-Fi as a bridge, the POI coordinates can be corrected, the rendering is supported to be more accurate, and the upstream service can be supported by the more accurate POI coordinates.

step 803: binding the Wi-Fi with the building to provide building-level route navigation for the service request;

step 804: acquiring a service destination address for sending the service request;

step 805: determining a target building corresponding to the Wi-Fi according to the destination address of the server;

in the step, firstly, service requests sent by a plurality of other users of the same building where the service destination address is located and a surrounding Wi-Fi list when each service request is sent are obtained; boundary information of all building data, and a plurality of pieces of trajectory data in response to the configuration request; identifying building address information where each Wi-Fi in each Wi-Fi list is located; preprocessing each piece of track data in the plurality of pieces of track data to obtain key point data of the plurality of tracks; aggregating the key point data of the plurality of tracks, and selecting the area with the largest number of key points as a two-dimensional Gaussian distribution center point; judging that the building with the shortest boundary distance from the two-dimensional Gaussian distribution center point to the building data is a target building; and binding the Wi-Fi of the service request with the target building to obtain the Wi-Fi of the target building.
