[0010] In a fourth aspect, some embodiments of the present disclosure provide a computer-readable medium having a computer program stored thereon, wherein when the program is executed by a processor, the method described in any implementation of the first aspect is implemented.

[0011] The above-mentioned various embodiments of the present disclosure have the following beneficial effects: through the information display method of some embodiments of the present 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 will be offset, which will cause the located store address to be not accurate enough, and then, the matching store information is not accurate enough. Based on this, the information display method of some embodiments of the present disclosure, first, in response to determining that the target user calls the target camera on the target terminal to obtain the item image, and determines whether the above-mentioned item image contains a QR code image. In actual situations, after the user performs a value operation (for example, a purchase operation) in the store, it is often necessary to settle the bill in the end. The present disclosure uses the camera on the target terminal (for example, the target user's mobile phone) to scan the QR code image contained in the item image corresponding to the item, which only requires the user to settle the bill by himself, greatly reducing the settlement cost. Then, in response to determining that the above-mentioned item image contains a QR code image, it is determined whether the above-mentioned target terminal has turned on location positioning. Secondly, in response to determining that the target terminal has not enabled location positioning, a search is performed for wireless signals within 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 target terminal's location as the center and a first target radius as the radius. The wireless signal information in the at least one piece of wireless signal information includes wireless signal strength and a signal transmitter identifier. Then, wireless signal information including wireless signal strength that meets the filtering criteria is filtered out from the at least one piece of wireless signal information as the target wireless signal information. In practice, when users check out on their own, it is often necessary to determine which store the purchased item belongs to based on location positioning. When the user does not enable location positioning or enables location positioning but the positioning signal is weak, store positioning will fail. This will affect the user's checkout efficiency and user experience. Therefore, the present disclosure significantly improves positioning accuracy by searching for wireless signals around the user (e.g., wireless signals emitted by a router) and performing auxiliary positioning based on the location of the terminal transmitting the wireless signal. In addition, when searching for wireless signals, multiple wireless signals are often found. However, the signal strengths of the wireless signals in the multiple wireless signals often vary. To ensure normal communication between the target terminal and the terminal transmitting the wireless signal, that is, to ensure that the data frames sent to each other during communication are complete, it is necessary to filter out the wireless signal information with stronger wireless signal strength based on the wireless signal strengths in the multiple wireless signal information, and use this as the target wireless signal information to ensure normal communication between the target terminal and the terminal transmitting the wireless signal. Then, in response to determining that location information matching the signal transmitter identifier included in the target wireless signal information exists in the first target database, the location information matching the signal transmitter identifier included in the target wireless signal information is determined as the first location information.In practice, querying a record in a database containing location information corresponding to terminals with wireless signal transmission capabilities for stores takes time proportional to the amount of data stored in the database. That is, the more data stored in the database, the longer the query takes. Therefore, querying the first target database often improves query speed because the first target database stores the location information of terminals with wireless signal transmission capabilities that have historically communicated with the target terminal. Furthermore, location information corresponding to a second target area is selected as the second location information, obtaining at least one second location information. The second target area is an area centered on the location corresponding to the first location information and with a second target radius as the radius. Furthermore, a location information list is generated based on the first location information and the at least one second location information. Finally, the location information list is displayed on the target display interface. This approach avoids the problem of address deviation caused by weak positioning signals, significantly improving the accuracy of matched store information. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] It should be understood that Figure 1 The number of computing devices in the embodiment is merely illustrative. Any number of computing devices may be provided according to implementation requirements.

[0030] Continue to refer Figure 2 , shows a process 200 of some embodiments of the information display method according to the present disclosure. The information display method includes the following steps:

[0031] Step 201: In response to determining that a target user calls a target camera on a target terminal to obtain an image of an object, it is determined whether the image of the object includes a QR code image.

[0032] In some embodiments, the execution subject of the information display method (eg Figure 1 The computing device 101 shown in FIG. 1 may determine whether the object image contains a QR code image in response to determining that a target user has invoked a target camera on a target terminal to capture an object image. The target user may be a user who owns the target terminal. The target terminal is a terminal equipped with the target camera. For example, the target terminal may be a mobile phone. The target camera is a rear-facing camera installed on the target terminal. The object image is an image of a target object captured by the target camera. The target object is an object containing a QR code. For example, the target object may be a beverage with a QR code. The execution entity may determine whether the target user has invoked the target camera to capture the object image based on camera status information corresponding to the target camera. Camera status information is information indicating the state of the target camera. For example, the camera status may be "1." Alternatively, the camera status may be "0." When the camera status is "1," the target camera is on. When the camera status is "0," the target camera is off. The execution entity may determine whether the object image contains the QR code image using a QR code recognition algorithm. The above-mentioned QR code recognition algorithm can be but is not limited to any one of the following: BRIEF (Binary Robust Independent Elementary Features, feature point description algorithm) algorithm, BRISK (Binary Robust Invariant Scalable Keypoints, binary-coded feature descriptor algorithm) algorithm and ORB (Oriented Fast and Rotated Brief, feature detection vector creation algorithm) algorithm.

[0033] Step 202: In response to determining that the object image includes a QR code image, determine whether the target terminal has enabled position positioning.

[0034] In some embodiments, the execution entity determines whether the target terminal has turned on location positioning in response to determining that the object image contains a QR code image. The execution entity may determine whether the target terminal has turned on location positioning based on the location positioning status information corresponding to the target terminal. The location positioning status information may be information indicating whether the target terminal has turned on the location positioning function. For example, the location positioning status information may be "1". The location positioning status information may also be "0". When the location positioning status information is "1", it indicates that the target terminal has turned on location positioning. When the location positioning status information is "0", it indicates that the target terminal has not turned on location positioning. The location positioning function is a function for performing location positioning. The execution entity may realize the location positioning function by positioning through GPS (Global Positioning System).

[0035] Step 203: In response to determining that the target terminal has not enabled position positioning, searching for wireless signals in the first target area to obtain at least one piece of wireless signal information.

[0036] In some embodiments, in response to determining that the target terminal does not enable location positioning, the execution subject searches for wireless signals in the first target area to obtain at least one piece of wireless signal information, which may include the following steps:

[0037] In the first step, a request frame is broadcast in the first target area.

[0038] The first target area may be a circular area with the location of the target terminal as the center and the first target radius as the radius. The first target radius may be the maximum radius for the target terminal to broadcast a request. For example, the first target radius may be 5 meters. The request frame is a data frame used to make a communication request to a terminal with request receiving capability within the first target area. For example, the terminal with request receiving capability may be a router. The execution entity may broadcast the request frame within the first target area using a full-duplex communication method. The execution entity may also broadcast the request frame within the first target area using a half-duplex communication method.

[0039] The second step is to obtain the wireless signal information sent by the terminal that receives the request frame in the first target area to obtain the at least one wireless signal information.

[0040] The execution entity may obtain the wireless signal information transmitted by the terminal that receives the request frame within the first target area through a wireless connection to obtain the at least one wireless signal information. The wireless signal information in the at least one wireless signal information may include wireless signal strength and a signal transmitter identifier. The wireless signal strength represents the strength of the wireless signal transmitted by the terminal that receives the request frame. The signal transmitter identifier is a unique identifier of the terminal that receives the request frame.

[0041] As an example, the wireless signal information in the at least one wireless signal information may be [wireless signal strength: -20 decibel milliwatts, signal transmitter identifier: 0001].

[0042] Step 204: Filter out wireless signal information including wireless signal strength that meets a filtering condition from the at least one wireless signal information as target wireless signal information.

[0043] In some embodiments, the execution entity selects, from the at least one wireless signal information, wireless signal information whose wireless signal strength satisfies a screening condition as the target wireless signal information. The screening condition may be that the wireless signal strength included in the wireless signal information is the strongest wireless signal strength among the wireless signal strengths included in the at least one wireless signal information.

[0044] For example, the at least one wireless signal information may include: {[wireless signal strength: -10 dBm, signal transmitter identifier: 0001], [wireless signal strength: -20 dBm, signal transmitter identifier: 0002], [wireless signal strength: -30 dBm, signal transmitter identifier: 0003]}. The wireless signal information selected to meet the above filtering conditions may include [wireless signal strength: -10 dBm, signal transmitter identifier: 0001].

[0045] Step 205 : In response to determining that the first target database contains location information matching the signal transmitter identifier included in the target wireless signal information, the location information matching the signal transmitter identifier included in the target wireless signal information is determined as the first location information.

[0046] In some embodiments, in response to determining that the first target database contains location information that matches the signal transmitter identifier included in the target wireless signal information, the execution entity determines the location information that matches the signal transmitter identifier included in the target wireless signal information as the first location information, which may include the following steps:

[0047] The first step is to send the above-mentioned target wireless signal information to the target server, so that the above-mentioned target server uses the signal transmitter identifier included in the above-mentioned target wireless signal information as a keyword, queries the location information that matches the signal transmitter identifier included in the above-mentioned target wireless signal information from the above-mentioned first target database, and determines it as the above-mentioned first location information.

[0048] The execution entity may transmit the target wireless signal information to a target server via a wired or wireless connection. The target server is a server that includes the first target database. For example, the target server may be a distributed server. The first target database is a database that stores terminal information. The terminal information may include a terminal identifier and terminal location information. The terminal identifier is a unique identifier of a terminal with request-receiving capability. The terminal location information is location information corresponding to the location of the terminal with request-receiving capability. The terminal with request-receiving capability is a terminal within a target store. For example, the terminal with request-receiving capability may be a router. The target store may be a store where a user performs a value operation. The value operation may be a "purchase operation." The target server may use a SQL (Structured Query Language) statement, using the signal transmitter identifier included in the target wireless signal information as a keyword, to query the first target database for location information that matches the signal transmitter identifier included in the target wireless signal information. For example, the SQL statement may be: SELECT * FROM first target database WHERE terminal identifier == signal transmitter identifier included in the target wireless signal information.

[0049] The second step is to receive the first location information sent by the target server.

[0050] The execution entity may receive the first location information sent by the target server via a wired connection or a wireless connection.

[0051] Step 206 : Filter out the location information whose corresponding location is located in the second target area as the second location information, and obtain at least one second location information.

[0052] In some embodiments, the execution entity may filter out the location information whose corresponding location is located in the second target area as the second location information, and obtain at least one second location information. The second target area is an area with the location corresponding to the first location information as the center and the second target radius as the radius. The second target radius may be a preset radius. For example, the preset radius may be 2 kilometers. For each location information in the second target database, the execution entity may determine the distance value between the coordinates of the location corresponding to the location information and the coordinates of the location corresponding to the first location information, and in response to determining that the distance value is less than the second target radius, determine the location information as the second location information. The first location information may include: a store identification and a store location. The second location information may include: a store identification and a store location. The store location represents the location of the store corresponding to the store identification. The store location can be represented by the location coordinates of the store corresponding to the store identification.

[0053] As an example, the above-mentioned location information may be [store ID: 00001, store location: (12322, 13, 132)].

[0054] Step 207: Generate a location information list according to the first location information and at least one second location information.

[0055] In some embodiments, the execution entity generates the location information list based on the first location information and the at least one second location information, which may include the following steps:

[0056] In the first step, a distance between a position corresponding to the second position information in the at least one second position information and a position corresponding to the first position information is determined to generate a candidate distance value, thereby obtaining at least one candidate distance value.

[0057] Among them, the above-mentioned execution entity can determine the distance between the store location included in the second location information of the above-mentioned at least one second location information and the store location included in the above-mentioned first location information through the distance formula between two points to generate a candidate distance value and obtain at least one candidate distance value.

[0058] In a second step, the position information in the at least one second position information is sorted according to the at least one candidate distance value to generate a candidate position information queue.

[0059] The execution entity may sort the location information in the at least one second location information according to the at least one candidate distance value using a target sorting algorithm to generate a candidate location information queue. The target sorting algorithm may be, but is not limited to, any one of the following: a bubble sort algorithm, a quick sort algorithm, and a shell sort algorithm.

[0060] The third step is to insert the first position information into the target position in the candidate position information queue to generate the position information list.

[0061] The target position may be the starting position of the candidate position information queue.

[0062] As an example, the candidate location information queue may be [A candidate location information, B candidate location information], and the location information list may be [first location information, A candidate location information, B candidate location information].

[0063] Step 208: Display the location information list on the target display interface.

[0064] In some embodiments, the execution entity may display the location information in the location information list on the target display interface. The execution entity may display the target display interface on the target terminal.

[0065] As an example, the target display interface can be as follows Figure 3 The target terminal 301 may include the target display interface 302. The display interface 302 may be used to display the location information 303 in the location information list.

[0066] The above-mentioned various embodiments of the present disclosure have the following beneficial effects: through the information display method of some embodiments of the present 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 will be offset, which will cause the located store address to be not accurate enough, and then, the matching store information is not accurate enough. Based on this, the information display method of some embodiments of the present disclosure, first, in response to determining that the target user calls the target camera on the target terminal to obtain the item image, and determines whether the above-mentioned item image contains a QR code image. In actual situations, after the user performs a value operation (for example, a purchase operation) in the store, it is often necessary to settle the bill in the end. The present disclosure uses the camera on the target terminal (for example, the target user's mobile phone) to scan the QR code image contained in the item image corresponding to the item, which only requires the user to settle the bill by himself, greatly reducing the settlement cost. Then, in response to determining that the above-mentioned item image contains a QR code image, it is determined whether the above-mentioned target terminal has turned on location positioning. Secondly, in response to determining that the target terminal has not enabled location positioning, a search is performed for wireless signals within 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 target terminal's location as the center and a first target radius as the radius. The wireless signal information in the at least one piece of wireless signal information includes wireless signal strength and a signal transmitter identifier. Then, wireless signal information including wireless signal strength that meets the filtering criteria is filtered out from the at least one piece of wireless signal information as the target wireless signal information. In practice, when users check out on their own, it is often necessary to determine which store the purchased item belongs to based on location positioning. When the user does not enable location positioning or enables location positioning but the positioning signal is weak, store positioning will fail. This will affect the user's checkout efficiency and user experience. Therefore, the present disclosure significantly improves positioning accuracy by searching for wireless signals around the user (e.g., wireless signals emitted by a router) and performing auxiliary positioning based on the location of the terminal transmitting the wireless signal. In addition, when searching for wireless signals, multiple wireless signals are often found. However, the signal strengths of the wireless signals in the multiple wireless signals often vary.

Furthermore, location information corresponding to a second target area is selected as the second location information, obtaining at least one second location information. The second target area is an area centered on the location corresponding to the first location information and with a second target radius as the radius. Furthermore, a location information list is generated based on the first location information and the at least one second location information. Finally, the location information list is displayed on the target display interface. This approach avoids the problem of address deviation caused by weak positioning signals, significantly improving the accuracy of matched store information.

[0067] Further references Figure 4 , which shows a process 400 of another embodiment of the information display method. The process 400 of the information display method includes the following steps:

[0068] Step 401: In response to determining that a target user calls a target camera on a target terminal to obtain an image of an object, it is determined whether the image of the object includes a QR code image.

[0069] In some embodiments, the execution subject, in response to determining that the target user calls the target camera on the target terminal to obtain an image of the item, and determines whether the image of the item includes a QR code image, may include the following steps:

[0070] In the first step, the object image is preprocessed to generate a first object image.

[0071] Among them, the execution subject of the information display method (for example Figure 1 The computing device 101 shown in FIG. 1 may pre-process the item image to generate a first item image. The pre-processing may be, but is not limited to, any one of the following: grayscale processing and binarization processing.

[0072] In the second step, noise is filtered on the first object image to generate a second object image.

[0073] The execution entity may filter noise from the first object image using a noise filtering algorithm to generate the second object image. The noise filtering algorithm may be an algorithm for filtering noise from the first object image. The noise filtering algorithm may be, but is not limited to, any one of the following: a noise reduction algorithm based on a median filter and a noise reduction algorithm based on a Gaussian filter.

[0074] The third step is to perform mathematical morphological operations on the second object image to generate a connected image.

The mathematical morphological operation may be, but is not limited to, any one of the following: an erosion operation, a dilation operation, an opening operation, and a closing operation.

[0076] The fourth step is to determine whether there is a sub-image set in the connected image.

[0077] The sub-images in the sub-image set have the same area, and the number of sub-images in the sub-image set is a target number, which may be 3. The execution entity may use a contour extraction algorithm to determine whether the sub-image set exists in the connected image.

[0078] For example, the execution entity may determine whether the sub-image set exists in the connected image by using findContour() in OpenCV.

[0079] In a fifth step, in response to determining that a sub-image set exists in the connected image, a QR code image included in the object image is determined based on the sub-image set.

[0080] The execution subject may determine the QR code image included in the object image according to the sub-image set in response to determining that there is a sub-image set in the connected image.

[0081] As an example, the execution entity may sequentially connect the center points of the sub-images in the sub-image set, and determine the image within the enclosed area as the QR code image included in the object image.

[0082] Step 402 : In response to determining that the target user calls the target camera on the target terminal to obtain an image of the object, the candidate wireless signal information stored in the target terminal is sent to the target server for storage.

[0083] In some embodiments, the execution subject may, in response to determining that the target user calls the target camera on the target terminal to obtain an image of the object, send the candidate wireless signal information stored in the target terminal to the target server for storage. The candidate wireless signal information may be historical wireless signal information stored in the target terminal. The execution subject may send the candidate wireless signal information stored in the target terminal to the target server for storage via a wired connection or a wireless connection. The target server is a server that includes the first target database. For example, the target server may be a distributed server. The first target database is a database that stores terminal information. The terminal information may include: a terminal identifier and terminal location information. The terminal identifier is a unique identifier of a terminal with request reception capability. The terminal location information is location information corresponding to the location of the terminal with request reception capability.

[0084] Step 403 : In response to determining that the object image includes a QR code image, determining whether the target terminal has enabled position positioning.

[0085] In some embodiments, the specific implementation of step 402 and the resulting technical effects can be referred to Figure 2 The corresponding step 202 in the embodiments will not be described in detail here.

[0086] Step 404: Scan the wireless signal in the first target area at predetermined intervals within the target time range.

[0087] In some embodiments, the execution entity may scan for wireless signals within the first target area at predetermined intervals within a target time range. The target time range may be a time range of 1 second. The predetermined time range may be 0.1 seconds. The execution entity may scan at least one channel within the first target area to receive data frames sent by a terminal transmitting a wireless signal.

[0088] Step 405 : In response to determining that a wireless signal exists in the first target area, a data frame sent by a terminal that transmits the wireless signal is acquired to obtain at least one data frame.

[0089] In some embodiments, in response to determining the presence of a wireless signal within the first target area, the execution entity obtains data frames sent by a terminal transmitting the wireless signal to obtain at least one data frame. The data frames in the at least one data frame are data frames used by a terminal with data transmission capability within the first target area to communicate with a target terminal. The execution entity may obtain the data frames sent by the terminal transmitting the wireless signal via a wireless connection to obtain the at least one data frame.

[0090] Step 406: For each data frame in the at least one data frame, determine whether the data of the data frame is complete. In response to determining that the data frame is complete, read wireless signal information from the data frame.

[0091] In some embodiments, the execution subject determines, for each data frame in at least one data frame, whether the data of the data frame is complete, and in response to determining that the data frame is complete, reading wireless signal information from the data frame may include the following steps:

[0092] The first step is to determine the identification field included in the above data frame.

[0093] The second step is to determine whether the data frame is complete based on the identification field.

[0094] The identification field may be a field used to indicate whether the data frame is complete. The execution entity may perform a data frame check operation on the information field included in the data frame using a data frame check algorithm to obtain a data frame check value. The data frame check algorithm may be an algorithm used to verify whether the data frame is complete. The data frame check algorithm may be, but is not limited to, any of the following: a cyclic redundancy check algorithm and an MD5 message digest algorithm.

[0095] Step 407: Filter out wireless signal information including wireless signal strength that meets a filtering condition from the at least one wireless signal information as target wireless signal information.

[0096] In some embodiments, the specific implementation of step 407 and the resulting technical effects can be referred to Figure 2 Step 204 in the corresponding embodiments will not be described in detail here.

[0097] Step 408: In response to determining that the first target database does not contain location information matching the signal transmitter identifier included in the target wireless signal information, the location information matching the target wireless signal information in the second target database is determined as the first location information.

[0098] In some embodiments, in response to determining that the first target database does not contain location information matching the signal transmitter identifier included in the target wireless signal information, the execution entity determines the location information matching the target wireless signal information in the second target database as the first location information. The execution entity may use an SQL statement to filter the location information matching the target wireless signal information from the second target database to obtain the first location information. For example, the SQL statement may be: SELECT * FROM second target database WHERE terminal identifier == signal transmitter identifier included in the target wireless signal information.

[0099] Step 409 : In response to determining that the first target database contains location information matching the signal transmitter identifier included in the target wireless signal information, the location information matching the signal transmitter identifier included in the target wireless signal information is determined as the first location information.

[0100] Step 410 : Filter out the location information corresponding to the location in the second target area as the second location information, and obtain at least one second location information.

[0101] Step 411: Generate a location information list according to the first location information and at least one second location information.

[0102] In some embodiments, the specific implementation of steps 409-411 and the resulting technical effects can be referred to Figure 2 The corresponding steps 205-207 in the embodiments are not described in detail here.

[0103] Step 412: Display the location information list on the target display interface.

[0104] In some embodiments, the execution entity may display the location information list on the target display interface, which may include the following steps:

[0105] The first step is to generate at least one information selection box according to the number of information selection boxes.

[0106] The number of the information selection boxes is the same as the number of the location information in the location information list. The information selection box may be a selection box for displaying to the target user to select the location information in the location information list.

[0107] In the second step, the location information in the location information list is filled into the information selection box of the at least one information selection box to generate at least one candidate information selection box.

[0108] The execution entity may sequentially fill the location information in the location information list into the information selection box of the at least one information selection box.

[0109] The third step is to display the at least one candidate information selection box on the target display interface.

[0110] As an example, the target display interface can be as follows Figure 5 The target terminal 501 includes the target display interface 502. The target display interface 502 can be used to display a candidate information selection box 503 in the location information list. The candidate information selection box 503 includes location information 504 in the location information list.

[0111] from Figure 4It can be seen that Figure 2 Compared with the description of some corresponding embodiments, the present disclosure periodically scans for signals within a target time range. When a wireless signal is scanned, the integrity of the data frame is determined, thereby ensuring the stability and smoothness of subsequent wireless communications.
