The above embodiments of the present disclosure have the following beneficial effects: by the information display method of some embodiments of the disclosure, the accuracy of matching the store information corresponding to the target store is improved. Specifically, the reason why the matched store information is not accurate enough is that: when the positioning signal is weak, the positioning address is deviated, so that the positioned shop address is not accurate enough, and further, the matched shop information is not accurate enough. Based on this, in the information display method of some embodiments of the present disclosure, first, in response to determining that a target user invokes a target camera on a target terminal to acquire an article image, it is determined whether the article image includes a two-dimensional code image. In practice, after a user performs a value operation (e.g., a purchase operation) in a store, the user often needs to settle a bill. According to the method, the camera on the target terminal (for example, a mobile phone of a target user) is adopted, and the two-dimensional code image contained in the article image corresponding to the article is scanned, so that only the user needs to settle accounts by himself, and the settlement cost is greatly reduced. And then, in response to the fact that the article image contains the two-dimensional code image, determining whether the target terminal is started to be positioned or not. Secondly, in response to determining that the target terminal is not positioned at the open position, searching for a wireless signal in a first target area to obtain at least one piece of wireless signal information, wherein the first target area is a circular area with the position of the target terminal as a circle center and a first target radius as a radius, and the wireless signal information in the at least one piece of wireless signal information comprises: wireless signal strength and signal transmitting terminal identification. And then, screening out wireless signal information with the wireless signal intensity meeting the screening condition from the at least one piece of wireless signal information to be used as target wireless signal information. In practical situations, when a user performs self-settlement, it is often necessary to determine which shop the item purchased by the user belongs to based on location positioning. When the user does not turn on the positioning or turns on the positioning, but the positioning signal is weak, the shop positioning is failed. Therefore, the settlement efficiency of the user and the user experience are influenced. Therefore, the positioning accuracy is greatly improved by searching wireless signals (such as wireless signals sent by a router) around the user and performing auxiliary positioning according to the position of the terminal transmitting the wireless signals. In addition, when searching for a wireless signal, a plurality of wireless signals are often searched, but the signal strengths of the wireless signals in the plurality of wireless signals are often different, and in order to ensure that the target terminal and the terminal that transmits the wireless signal communicate normally, that is, the data frames that are mutually transmitted during communication are complete, therefore, the wireless signal information with strong wireless signal strength needs to be screened out according to the wireless signal strengths in the plurality of wireless signal information, and is used as the target wireless signal information, so as to ensure that the target terminal and the terminal that transmits the wireless signal communicate normally. Then, in response to determining that there is location information in the first target database that matches the signal transmitting terminal identification included in the target wireless signal information, the location information that matches the signal transmitting terminal identification included in the target wireless signal information is determined as first location information. In practical situations, a record is queried in a database containing position information corresponding to a terminal with wireless signal transmitting capability of a shop, and the query time is in direct proportion to the amount of data stored in the database, namely, the more data stored in the database, the more time consumed by the query. Thus, by making an inquiry at the first target database, the first target database stores location information for terminals having wireless signal transmission capabilities that have historically communicated with the target terminals. Therefore, by querying the first target data, the query speed tends to be increased. Further, screening out position information of which the corresponding position is located in a second target area as second position information, and obtaining at least one piece of second position information, wherein the second target area is an area with the position corresponding to the first position information as the center and the radius of a second target as the radius. In addition, a location information list is generated based on the first location information and the at least one second location information. And finally, displaying the position information list on a target display interface. By the method, the problem that the positioning address is deviated due to weak positioning signals can be avoided. The accuracy of the matched shop information is greatly improved.

With continued reference to fig. 2, a flow 200 of some embodiments of an information presentation method according to the present disclosure is shown. The information display method comprises the following steps:
In some embodiments, an executing body of the information presentation method (e.g., the computing device 101 shown in fig. 1) may determine whether the item image contains a two-dimensional code image in response to determining that the target user invokes a target camera on the target terminal to acquire the item image. The target user may be a user who owns the target terminal. The target terminal is a terminal provided with the target camera. For example, the target terminal may be a "mobile phone". The target camera is a rear camera mounted on the target terminal. The object image is an object image corresponding to the target object acquired by the target camera. Wherein, the target object is an object containing a two-dimensional code. For example, the target item may be "beverage" having a two-dimensional code. The execution main body can determine whether the target user calls the target camera to acquire the article image according to the camera state information corresponding to the target camera. The camera state information is information for representing the state of the target camera. For example, the above-described camera state may be "1". The above-described camera state may also be "0". And when the camera state is 1, representing that the target camera is in an open state. And when the camera state is 0, representing that the target camera is in a closed state. The execution subject may determine whether the two-dimensional code image exists in the article image through a two-dimensional code recognition algorithm. The two-dimensional code recognition algorithm can be, but is not limited to, any one of the following: BRIEF (Binary robusts Independent element Features algorithms), BRISK (Binary robusts invertible keys algorithms based on Binary coding) and ORB (ordered Fast and indexed BRIEF) algorithms.
In some embodiments, the executing body determines whether the target terminal is open for position location in response to determining that the article image includes a two-dimensional code image. The execution main body can determine whether the target terminal is started to perform position location according to the position location state information corresponding to the target terminal. The position location state information may be information indicating whether the target terminal starts a position location function. For example, the above position location state information may be "1". The above position location state information may also be "0". And when the position positioning state information is '1', representing the starting position positioning of the target terminal. And when the position positioning state information is '0', representing that the target terminal is not opened for position positioning. The position locating function is a function for locating a position. The execution body may perform Positioning by a Global Positioning System (GPS) to realize the position Positioning function.
In some embodiments, the executing body, in response to determining that the target terminal does not start position location, searches for a wireless signal in the first target area to obtain at least one piece of wireless signal information, may include the following steps:
in a first step, a request frame is broadcast within a first target area.
The first target area may be a circular area with a center of a circle at the position of the target terminal and a radius of the first target as a radius. The first target radius may be a maximum radius of the target terminal performing the broadcast request. For example, the first target radius may be 5 meters. The request frame is a data frame for requesting a communication to a terminal having a request receiving capability in the first target area. The terminal having the request receiving capability described above may be a router, for example. The execution body may broadcast the request frame in the first target area in a full duplex communication manner. The execution body may broadcast the request frame in the first target area by a half-duplex communication method.
And secondly, acquiring wireless signal information sent by the terminal receiving the request frame in the first target area to obtain the at least one piece of wireless signal information.
The execution main body may obtain, in a wireless connection manner, the wireless signal information sent by the terminal that receives the request frame in the first target area, so as to obtain the at least one piece of wireless signal information. The wireless signal information in the at least one piece of wireless signal information may include: wireless signal strength and signal transmitting terminal identification. The wireless signal strength represents the strength of the wireless signal transmitted by the terminal receiving the request frame. The signal transmitting terminal identification is the unique identification of the terminal receiving the request frame.
As an example, the wireless signal information in the at least one wireless signal information may be [ wireless signal strength: -20 db mw, signal transmitting end identification: 0001].
And 204, screening out wireless signal information with wireless signal strength meeting the screening condition from at least one piece of wireless signal information as target wireless signal information.
In some embodiments, the execution main body screens out, from the at least one wireless signal information, wireless signal information included in the wireless signal information whose wireless signal strength satisfies the screening condition as the target wireless signal information. The screening condition may be that the radio signal strength included in the radio signal information is the radio signal strength with the strongest signal strength among the radio signal strengths included in the radio signal information of the at least one piece of radio signal information.
As an example, the at least one wireless signal information may be: { [ wireless signal strength: -10 db mw, signal transmitting end identifier: 0001, [ wireless signal strength: -20 db mw ], signal transmitting end identification: 0002, [ wireless signal strength: -30 db mw, [ signal transmitting end identification: 0003]}. The wireless signal information that satisfies the above-mentioned screening condition may be [ wireless signal strength: -10 db mw, signal transmitting end identifier: 0001].
In some embodiments, the executing body, in response to determining that there is location information matching the signal transmitting terminal identifier included in the target wireless signal information in the first target database, determines location information matching the signal transmitting terminal identifier included in the target wireless signal information as the first location information, may include the steps of:
first, the target wireless signal information is sent to a target server, so that the target server uses a signal transmitting terminal identifier included in the target wireless signal information as a keyword, and location information matched with the signal transmitting terminal identifier included in the target wireless signal information is inquired from the first target database and determined as the first location information.
The execution main body can send the target wireless signal information to a target server in a wired connection or wireless connection mode. The target server is a server including the first target database. For example, the target server may be a distributed server. The first target database is a database in which terminal information is stored. The terminal information may include: and the terminal identification and the position information of the terminal. The terminal identification is a unique identification of the terminal having the request receiving capability. The location information of the terminal is the location information corresponding to the location of the terminal with the request receiving capability. The terminal with the request receiving capability is a terminal in a target shop. For example, the terminal having the request receiving capability may be a router. The target store may be a store in which a user performs a value operation. The value operation may be a "purchase operation". The target server may Query, from the first target database, location information that matches the signal transmitting terminal identifier included in the target wireless signal information, using the signal transmitting terminal identifier included in the target wireless signal information as a keyword, through an SQL (Structured Query Language) statement. For example, the SQL statement may be: SELECT × FROM first target database WHERE terminal identification = = signal transmitting end identification included in the target wireless signal information.
And a second step of receiving the first location information sent by the target server.
The execution main body may receive the first location information sent by the target server through a wired connection or a wireless connection.
And step 206, screening out the position information of which the corresponding position is located in the second target area as second position information to obtain at least one piece of second position information.
In some embodiments, the execution subject may filter out the location information of which the corresponding location is located in the second target area as the second location information, and obtain at least one piece of second location information. The second target area is an area having a position corresponding to the first position information as a center and a second target radius as a radius. The second target radius may be a preset radius. For example, the predetermined radius may be 2 km. For each location information in the second target database, the execution subject may determine a distance value between coordinates of a location corresponding to the location information and coordinates of a location corresponding to the first location information, and in response to determining that the distance value is less than a second target radius, determine the location information as the second location information. The first location information may include: store identification and store location. The second location information may include: a store identification and a store location. The shop position represents the position of the shop corresponding to the shop identifier. The store location may be represented by location coordinates of the store corresponding to the store identification.
As an example, the above location information may be [ store identification: 00001, store location: (12322, 13, 132) ].
In some embodiments, the executing body generating a location information list according to the first location information and the at least one second location information may include:
the first step is to determine a distance between a position corresponding to the second position information in the at least one piece of second position information and a position corresponding to the first position information to generate a candidate distance value, and obtain at least one candidate distance value.
The executing body may determine a distance between a shop location included in the second location information and a shop location included in the first location information in the at least one piece of second location information by using a distance formula between two points to generate a candidate distance value, and obtain at least one candidate distance value.
And secondly, sorting the position information in the at least one second position information according to the at least one candidate distance value to generate a candidate position information queue.
The execution subject may sort, by using a target sorting algorithm, the position information in the at least one second position information according to the at least one candidate distance value, so as to generate a candidate position information queue. The target ranking algorithm may be, but is not limited to, any of the following: bubble sort algorithm, quick sort algorithm, and hill sort algorithm.
And thirdly, inserting the first position information into the target position in the candidate position information queue to generate the position information list.
The target position may be a start position of the candidate position information queue.
As an example, the candidate position information queue described above may be [ a candidate position information, B candidate position information ]. The above-mentioned position information list may be [ first position information, a candidate position information, B candidate position information ].
And step 208, displaying the position information list on the target display interface.
In some embodiments, the execution subject may display the location information in the location information list on the target display interface. The execution body can display the target display interface on the target terminal.
As an example, the target presentation interface may be as shown in fig. 3. The target terminal 301 may include the target display interface 302. The presentation interface 302 may be used to present the location information 303 in the location information list.
The above embodiments of the present disclosure have the following beneficial effects: by the information display method of some embodiments of the disclosure, the accuracy of matching the store information corresponding to the target store is improved. Specifically, the reason why the matched store information is not accurate enough is that: when the positioning signal is weak, the positioning address is deviated, so that the positioned shop address is not accurate enough, and further, the matched shop information is not accurate enough. Based on this, in the information display method of some embodiments of the present disclosure, first, in response to determining that a target user invokes a target camera on a target terminal to acquire an article image, it is determined whether the article image includes a two-dimensional code image. In practice, after a user performs a value operation (e.g., a purchase operation) in a store, the user often needs to settle a bill. According to the method, the camera on the target terminal (for example, a mobile phone of a target user) is adopted, and the two-dimensional code image contained in the article image corresponding to the article is scanned, so that only the user needs to settle accounts by himself, and the settlement cost is greatly reduced. And then, in response to the fact that the article image contains the two-dimensional code image, determining whether the target terminal is opened for position location. Secondly, in response to determining that the target terminal is not positioned at the open position, searching for a wireless signal in a first target area to obtain at least one piece of wireless signal information, wherein the first target area is a circular area with the position of the target terminal as a circle center and a first target radius as a radius, and the wireless signal information in the at least one piece of wireless signal information comprises: wireless signal strength and signal transmitting terminal identification. Then, the wireless signal information which is included in the at least one wireless signal information and the wireless signal strength of which meets the screening condition is screened out to be used as the target wireless signal information. In practical situations, when a user performs self-settlement, it is often necessary to determine which shop the item purchased by the user belongs to based on location positioning. When the user does not turn on the positioning or turns on the positioning, but the positioning signal is weak, the shop positioning is failed. Therefore, the settlement efficiency of the user and the user experience are influenced. Therefore, the positioning accuracy is greatly improved by searching for wireless signals (such as wireless signals sent by a router) around the user and performing auxiliary positioning according to the position of the terminal sending the wireless signals. In addition, when searching for a wireless signal, a plurality of wireless signals are often searched, but the signal strengths of the wireless signals in the plurality of wireless signals are often different, and in order to ensure that the target terminal and the terminal that transmits the wireless signal communicate normally, that is, the data frames that are mutually transmitted during communication are complete, therefore, the wireless signal information with strong wireless signal strength needs to be screened out according to the wireless signal strengths in the plurality of wireless signal information, and is used as the target wireless signal information, so as to ensure that the target terminal and the terminal that transmits the wireless signal communicate normally.

Thus, by making an inquiry at the first target database, the first target database stores location information for terminals having wireless signal transmission capabilities that have historically communicated with the target terminals. Therefore, by querying the first target data, the query speed tends to be increased. And further, screening out position information of which the corresponding position is located in a second target area as second position information to obtain at least one piece of second position information, wherein the second target area is an area taking the position corresponding to the first position information as the center and taking the radius of the second target as the radius. In addition, a location information list is generated based on the first location information and the at least one second location information. And finally, displaying the position information list on a target display interface. By the method, the problem that the positioning address is deviated due to weak positioning signals can be avoided. The accuracy of the matched shop information is greatly improved.
