For another example, when the user's vision is limited and the specific location of the code image cannot be seen clearly, when the terminal device scans the code image, the entire code image is not completely in the scanning area, which can also lead to the problem of sending a scan failure.

[0032] In order to make the purpose, technical solutions and advantages of one or more embodiments of this specification clearer, the technical solutions of one or more embodiments of this specification will be clearly and completely described below in combination with the specific embodiments of this specification and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of one or more embodiments of this specification.

[0033] The technical solutions provided by the embodiments of this specification are described in detail below in conjunction with the accompanying drawings.

[0034] In the prior art, when users scan code to pay, merchants often provide code images corresponding to multiple payment platforms for users to scan in order to meet the users' various payment needs. In addition, in order to facilitate user scanning, the code images of multiple platforms are placed close to each other. In this case, when scanning, the user may open the "scan" function of payment platform A, but scan the code image corresponding to payment platform B. In some cases, for users who have just used scan code payment or visually impaired people, the user may not be able to determine which code image corresponds to the opened payment application. In this case, the user needs to ask the merchant to determine the correct code image, and then move the code scanning device to align the code image for scanning, resulting in reduced efficiency and success rate of scanning code images.

[0035] In order to solve the defects in the prior art, this solution provides the following embodiments:

[0036] A code scanning prompt method provided in the embodiment of the specification is specifically described in conjunction with the accompanying drawings:

[0037] Figure 1 The flowchart of a code scanning prompt method provided by the embodiment of this specification is as follows. From the program perspective, the execution subject of the process can be a program installed on the application server or an application client.

[0038] like Figure 1 As shown, the process may include the following steps:

[0039] Step 102: Acquire a first image within a scanning area of ​​a code scanning device; the first image includes a first partial image of a bearing layer for bearing the code image.

[0040] The code scanning device may be a device with a code scanning function. For example, it may be a mobile terminal with a code scanning function, such as a mobile phone or a tablet computer. The code scanning device may also scan barcodes and QR codes. Therefore, the code scanning device may also be a barcode scanning gun, a QR code scanner, a code scanning machine, and the like.

[0041] The scanning area may represent the range of the image area that the code scanning device can scan. The image in the scanning area may include a partial code image of the payment code, and may also include a first partial image of the carrier layer for carrying the code image. Of course, the image in the scanning area may not include the code image, but only include the first partial image of the carrier layer.

[0042] The carrier layer here may refer to a carrier for carrying a code image, for example, if the printed payment code is attached to a paper or plastic carrier, the carrier layer may be the paper or plastic carrier. If the payment code is displayed on a display screen of an electronic screen, the carrier layer may be a layer used to display the payment code and related information in the software that displays the screen.

[0043] It should be noted that the bearing layer for bearing the code image includes information related to the code image, for example, the bearing layer may have a background color, and there may be text, images, logos, etc. on the bearing layer.

[0044] Step 104: Determine first position information of the first partial image within the scanning area.

[0045] In practical applications, the size of the scanning area is fixed, and the position information of the image in the scanning area is also fixed. The position information mentioned here may be the position coordinates of the image in the scanning area.

[0046] Step 106: Based on the first position information, generate first prompt information for indicating a first direction; the first direction is used to indicate a direction from the center position of the scanning area to the position of the first partial image in the scanning area.

[0047] In actual applications, when a code image is scanned by a code scanning device, the entire code image is not completely within the scanning area or the scanning area does not contain the code image. In this case, in order to ensure successful scanning, the code scanning device can be moved according to the position information of the partial image of the carrier layer in the scanning area so that the scanning device can scan the code image. Specifically, the position information of the partial image of the carrier layer in the current scanning area can be determined in the scanning area, and then the center position of the scanning area is pointed to the direction of the position of the partial image in the scanning area, which is determined as the direction of movement of the code scanning device.

[0048] In a specific implementation, the coordinates of the center position of the partial image of the carrier layer in the scanning area can be determined, and the moving direction of the scanning device can be determined based on the coordinates of the center position of the partial image in the scanning area and the center coordinates of the scanning area.

[0049] The first prompt information may specifically include one or more prompt information in text form, graphic form, animation form and voice form. When prompting the user, the prompting method of the prompt information may be freely selected / combined according to the actual situation, and this specification embodiment does not specifically limit this.

[0050] Figure 1The method in the embodiment of the present invention obtains a first image in a scanning area of ​​a code scanning device; determines the position information of a first partial image of a carrier layer for carrying a code image contained in the first image in the scanning area; generates first prompt information indicating a first direction based on the position information; the first direction indicates a direction from the center of the scanning area to the position of the first partial image in the scanning area. Through the above method, prompt information prompting a user to move the code scanning device can be generated according to the position information of a partial image of the carrier layer in the scanning area, so as to guide the user to scan the code image. This improves the success rate of the user scanning the code image.

[0051] based on Figure 1 The method, the examples of this specification also provide some specific implementation plans of the method, which are described below.

[0052] Optionally, before determining the first position information of the first partial image in the scanning area, the method may further include:

[0053] Based on the partial image, identifying characteristic information of the bearing layer;

[0054] Determine whether the characteristic information is consistent with the target characteristic information to obtain a first determination result; the target characteristic information is characteristic information of a bearing layer of a target payment platform including a bearing code image;

[0055] The determining of the first position information of the first partial image within the scanning area may specifically include:

[0056] When the first judgment result indicates that the feature information is consistent with the target feature information, first position information of the first partial image within the scanning area is determined.

[0057] The characteristic information of the bearing layer may include one or more of the background color information of the bearing layer, the displayed text information, and the specific identification information. Among them, the displayed text information in the bearing layer may be a promotional term, or the Chinese name, Chinese name abbreviation, English name, English name abbreviation of the payment platform corresponding to the code image, or other text information related to the code image. The specific identification information may be information that uses a specific symbol or pattern to represent the payment platform corresponding to the code image.

[0058] The target characteristic information may represent characteristic information of the target payment platform's carrier layer. For example, the background color of the first payment platform's carrier layer is blue, and the carrier layer contains the name text information of the first payment platform, which is used to specifically refer to the special identifier A of the first payment platform.

[0059] By judging whether the characteristic information of the bearing layer in the scanning area is consistent with the target characteristic information, if they are consistent, it can be determined that the bearing layer in the scanning area matches the target payment platform.

[0060] In order to explain the above method in more detail, Figure 2 To explain:

[0061] Figure 2 It is a schematic diagram of the bearing layer characteristic information provided in the embodiment of this specification.

[0062] like Figure 2 As shown, taking a payment method as an example, the background 2011 color in the bearer layer 201 of the A payment platform is blue, and the text information in the bearer layer 201 includes: "Please specify A payment for payment", "A payment", "APAY", "Pay with A scan code" and "Open 'Scan' on the A homepage". The bearer layer 201 also includes specific identification information 2012. According to the color of the background 2011 in the bearer layer 201, the text content of the text information and the specific identification information 2012, it can be determined that the code image carried in the bearer layer 201 corresponds to the A payment platform.

[0063] The code area in the bearer layer 201 contains a code image 202, which matches the A platform.

[0064] It should be noted that when judging whether the characteristic information of the bearing layer is consistent with the target characteristic information of the bearing layer of the target payment platform, the judgment can be made based on only one kind of characteristic information, or a combination of multiple characteristic information can be used for judgment. For example: when it can be judged that only the text information of the bearing layer in the first part of the image is the same as the text information of the bearing layer of the target payment platform, it is determined that the characteristic information of the bearing layer is consistent with the target characteristic information of the bearing layer of the target payment platform. Or only the background color and identification information are judged to be the same, and the characteristic information of the bearing layer is determined to be consistent with the target characteristic information of the bearing layer of the target payment platform. It should be noted that the same text information is not limited to the same text content. It is only necessary to ensure that the payment platform name in the text is the same.

[0065] Of course, multiple characteristic information can also be judged at the same time. For example, only when all the characteristic information of the bearing layer in the first part of the image is the same as all the characteristic information of the bearing layer of the target payment platform, can it be determined that the characteristic information of the bearing layer is consistent with the target characteristic information of the bearing layer of the target payment platform.

[0066] It is also possible to freely combine multiple feature information for judgment. For example, if all background color information and text information of the carrier layer in the first part of the image are the same as the background color information and text information of the carrier layer of the target payment platform, or if all background color information and specific identification information of the carrier layer in the first part of the image are the same as the background color information and specific identification information of the carrier layer of the target payment platform, then it is determined that the feature information of the carrier layer is consistent with the target feature information of the carrier layer of the target payment platform.

[0067] Through the above method, based on the background color information, displayed text information, and one or more characteristic information in the specific identification information in the bearer layer of the code image, it can be determined whether the bearer layer matches the target payment institution. It is even possible to determine the payment platform corresponding to the bearer layer based on the characteristic information in the bearer layer, and when the user scans a bearer layer that does not match the application that performs the code scanning operation, a prompt message is displayed to the user to guide the user to move the code scanning device to scan the matching code image.

[0068] In practical applications, if the characteristic information of the carrier layer in the scanning area is consistent with the target characteristic information, the position information of the partial image of the carrier layer in the scanning area can be determined in the scanning area.

[0069] In actual applications, when it is determined that the characteristic information of the bearing layer in the scanning area is consistent with the target characteristic information, it can be determined that the bearing layer in the scanning area is the bearing layer where the payment code corresponding to the target payment platform is located. If the code image carried by the bearing layer is not completely scanned within the first preset time length, a first prompt information can be generated to prompt the user to move the code scanning device.

[0070] Through the above method, the payment platform corresponding to the code image can be determined based on the partial image of the carrying layer that carries the code image. If the payment platform is the target payment platform, prompt information indicating the moving direction of the scanning device is generated based on the position information of the carrying image in the scanning area to guide the user to scan the code image.

[0071] When guiding the user to scan the code image, the user moves the code scanning device to the location of the code image according to the first prompt information. When the code scanning device is moved to the point where a portion of the code image can be scanned, the image in the code scanning area includes a portion of the code image and a portion of the carrier layer image. At this time, since the complete code image is still not included, the code image cannot be scanned. In this case, the following method can be used to guide the user to complete the scanning:

[0072] Optionally, the above method may further include:

[0073] After the code scanning device is moved, a second image within the scanning area of ​​the code scanning device is acquired; the second image includes a second partial image of the bearing layer bearing the code image;

[0074] Determining second position information of the code image in the second partial image;

[0075] Based on the second position information, second prompt information for indicating a second direction is generated; the second direction is used to indicate a direction from the center position of the scanning area to the second position of the code image in the second partial image.

[0076] The second image may represent an image in the scanning area after the code scanning device is moved. The second image includes a second partial image of the carrier layer that carries the code image, and further, the second image may include a partial image of the code image.

[0077] At this time, since the second image in the scanning area includes a partial image of the code image, the second position information of the code image in the second image in the scanning area can be determined. According to the position of the partial code image in the scanning area, the user is prompted to move the code scanning device in the second direction so that the code scanning device can scan the complete code image. The second direction can be used to indicate the direction from the center position of the scanning area to the second position of the code image in the scanning area.

[0078] Through the above method, prompt information for prompting the moving direction of the code scanning device is generated according to the position information of the code image in the scanning area, so as to improve the efficiency of the user scanning the complete code image.

[0079] In actual applications, after the code scanning device is moved, for the visually impaired or those who do not know how to use code scanning payment, there may be a situation where the image scanned by the code scanning device does not include the code image. The scanned image also does not include text, images or logo information related to the code image, and the scanned image only includes the background color information of the carrier layer. At this time, the center position of the code image cannot be determined. This situation is generally caused by the distance between the scanning device and the area to be scanned being less than the preset distance, or being too close; or because the image distance of the camera of the code scanning device is too small. At this time, the user can be prompted to move the code scanning device further away from the area to be scanned or to increase the image distance of the camera. Of course, during the scanning process, even if the image in the code scanning area contains part of the code image or other information related to the code image, if the distance between the scanning device and the area to be scanned is less than the preset distance, the center position of the code image cannot be determined. It is also necessary to prompt the user to move the code scanning device further away from the area to be scanned or to increase the image distance of the camera.

[0080] Specifically, the above method may include the following steps:

[0081] After the code scanning device is moved, an image within a scanning area of ​​the code scanning device is acquired;

[0082] When the position of the code image cannot be determined according to the image in the scanning area of ​​the code scanning device, a prompt message is generated; the prompt message is used to prompt to increase the distance between the code scanning device and the area to be scanned or to increase the image distance.

[0083] It should be noted that the image in the above step does not include a code image, nor does it include text information or identification information related to the code image. The image may only include background color information of a carrier layer for carrying the code image.

[0084] Through the above method, when the distance between the code scanning device and the area to be scanned is less than the preset distance or the image distance is small, corresponding prompt information can be generated to prompt the user to increase the distance between the code scanning device and the area to be scanned or adjust the image distance to speed up the user's scanning process of the code image.

[0085] In practical applications, after the first position information of the first partial image in the scanning area is obtained, the moving direction of the scanning device is determined based on the first position information, which can be implemented by the following method:

[0086] The first position information may specifically be the position coordinates of the first partial image in the scanning area, wherein the position coordinates of the first partial image in the scanning area may specifically be the position coordinates of the center of the set of the first partial images in the scanning area.

[0087] Therefore, when determining the position coordinates of the first partial image in the scanning area, the geometric center of gravity of the first partial image may be determined first; and then the position coordinates of the geometric center of gravity in the scanning area may be determined.

[0088] Optionally, the generating first prompt information for indicating the first direction may specifically include:

[0089] determining the first direction based on the first position information;

[0090] Based on the first direction, the first prompt information is generated.

[0091] It should be noted that the geometric centroid can be defined as: any line passing through the geometric centroid can bisect the area of ​​a figure.

[0092] In actual applications, the first direction may refer to the specific direction in which the scanning device moves, which may include up, down, left, right, upper left, lower left, upper right, lower right and other directions.

[0093] Optionally, the determining the first direction may specifically include:

[0094] Determine first position coordinates of the first partial image within the scanning area;

[0095] Determine a second position coordinate of a center position of the scanning area;

[0096] The first direction is determined according to the first position coordinates and the second position coordinates.

[0097] Specifically, when the first direction is determined according to the first position coordinates and the second position coordinates, the azimuth may be calculated according to the first position coordinates and the second position coordinates, and the first prompt information may be generated according to the calculated azimuth.

[0098] When calculating the azimuth angle, assuming that the first position coordinate is A (x1, y1) and the second position coordinate is B (x2, y2), the azimuth angle can be calculated using the following formula:

[0099]

[0100] in, is the quadrant angle, Δx AB Indicates the vertical coordinate increment from point A to point B, Δy AB It represents the horizontal coordinate increment from point A to point B. The coordinate increment has two cases, positive and negative. According to the positive and negative of the horizontal and vertical coordinate increments, the quadrant can be determined. According to the quadrant, the quadrant angle can be converted into azimuth.

[0101] After the azimuth is calculated, generating first prompt information according to the calculated azimuth may specifically include:

[0102] Determine the direction angle range corresponding to the azimuth angle, determine the first direction corresponding to the azimuth angle according to the angle range corresponding to the azimuth angle, and generate first prompt information according to the first direction.

[0103] It can be understood that the specific angle value of the calculated azimuth is classified into a preset angle direction, and the first prompt information is generated according to the angle direction.

[0104] To improve practicality, the following methods can be used:

[0105] When the prompt information is broadcasted in voice mode, the direction of the prompt can be determined according to the calculated azimuth angle in accordance with the aforementioned method.

[0106] When prompt information is displayed in the form of an image such as an arrow, the prompt image is generated according to the actual angle of the calculated azimuth.

[0107] Of course, in actual applications, the above two methods can be combined to prompt the user. Specifically, when the actual angle of the azimuth is calculated, the actual angle is classified into the preset angle direction, and the angle direction is announced by voice. At the same time, the direction arrow image corresponding to the actual angle is displayed to the user. For example: the generated azimuth is 52.5°. At this time, 52.5° can be classified as the upper right direction. When prompting, a 52.5° direction arrow can be directly generated, and the direction arrow can be displayed to the user as a prompt message, and the voice broadcast "Please move the scanning device to the upper right direction" can be announced.

[0108] Through the above method, when the user scans the code to pay, a variety of prompt methods are provided to the user, which is convenient for the user to understand the prompt information and quickly operate the scanning device according to the prompt information.

[0109] Figure 3 This is the first schematic diagram for determining the moving direction of the scanning device during the scanning process provided by the embodiment of this specification.

[0110] like Figure 3 As shown, the first direction may refer to the specific direction in which the code scanning device moves. The first direction is preset to the angle areas corresponding to the eight directions of up, down, left, right, upper left, lower left, upper right, and lower right: Down Left right Top left Lower left Top right Bottom right At this time, assuming that the calculated azimuth because Therefore, the azimuth angle belongs to the upper right direction. A first prompt information may be generated to prompt the code scanning device to move to the upper right direction.

[0111] Through the above method, the calculated azimuth angle is matched to the preset direction angle range, and easy-to-understand direction prompt information is displayed to the user, so as to improve the efficiency of the user scanning the complete code image.

[0112] Generating the first prompt information according to the calculated azimuth angle may also include:

[0113] After the azimuth is calculated, the quadrant where the azimuth is located is determined;

[0114] Determine the moving direction of the code scanning device based on the quadrant area where the azimuth is located.

[0115] Figure 4This is the second schematic diagram for determining the moving direction of the scanning device during the scanning process provided in the embodiment of this specification.

[0116] like Figure 4 As shown, when the quadrant area to which the angle for determining the direction angle belongs is the first quadrant, the moving direction of the code scanning device is decomposed into two directions, right and upward; when it is the second quadrant, the moving direction of the code scanning device is decomposed into two directions, left and upward; when it is the third quadrant, the moving direction of the code scanning device is decomposed into two directions, left and downward; when it is the fourth quadrant, the moving direction of the code scanning device is decomposed into two directions, right and upward.

[0117] The code scanning device is prompted to move in any one of the decomposed directions. When the code scanning device moves, the position information of part of the image in the scanning area is calculated in real time according to the image scanned by the code scanning device; the moving direction of the code scanning device is calculated according to the position information calculated in real time.

[0118] It should be noted that during the movement of the code scanning device, there will be errors in the direction and angle in which the user moves the code scanning device. For example, when the code scanning device is instructed to move to the right, it may not be guaranteed that the code scanning device can move parallel to the device without error. Based on this, in the embodiments of this specification, the moving direction of the code scanning device can be calculated in real time during the movement of the code scanning device. For example, when the prompt information instructs the user to move to the right, after the code scanning device moves a certain distance to the right, the moving direction of the code scanning device is calculated to be upward. At this time, a prompt information can be displayed to prompt the user to stop moving the code scanning device to the right and instruct the user to move the code scanning device upward.

[0119] For example: Calculate the azimuth At this time, if the prompt message displayed is "Please move the phone in the direction of 50°", the user's naked eyes cannot accurately identify the direction angle and cannot accurately move the code scanning device. Based on this, the quadrant where the azimuth is located can be determined first, and the moving route of the code scanning device can be decomposed into directions along the coordinate axis according to the quadrant, for example: azimuth hour, It belongs to the first quadrant. At this time, the user can be prompted to move to the right first, and when it moves to a certain distance, stop moving to the right and indicate to move upward, or the user can be prompted to move upward first, and when it moves to a certain distance, stop moving upward and indicate to move to the right.

[0120] Of course, in practical applications, the azimuth angles can be classified into the eight angle directions mentioned above: up, down, left, right, upper left, lower left, upper right, and lower right, and then these eight directions can be decomposed.

[0121] After decomposing the direction corresponding to the azimuth angle in the above manner, when prompting the user according to the decomposed moving direction, the above-mentioned method of improving practicality can be combined to prompt the user. Specifically, when prompting the user in the form of voice broadcast, the following steps can be included:

[0122] After the azimuth is calculated, the two basic moving directions corresponding to the azimuth can be decomposed according to the specific angle of the azimuth; the user is first prompted to move in the first basic direction, and after the user moves the code scanning device in the first basic direction for a period of time / distance, the user is prompted to move in the second basic direction. Specifically, the number of basic directions and the corresponding relationship between the direction angle and the basic direction can be limited according to the actual application scenario, and the embodiments of this specification do not make specific limitations on this.

[0123] In the above steps, it should be noted that when prompting the user to move the code scanning device in each basic direction, the user can be prompted in combination with the above method of improving practicality.

[0124] In actual applications, for the visually impaired, voice broadcasting can be preferred. When broadcasting, if the specific angle value is broadcast, it is difficult for the user to understand the moving direction. Therefore, when performing voice broadcasting, the specific angle of the direction angle is classified as a preset angle direction, and voice broadcasting is performed according to the angle direction, or the specific angle of the direction angle is decomposed into two basic moving directions, and the voice prompts the user to move in the two basic directions, which can improve the efficiency and success rate of the visually impaired scanning operation. In addition, the above method can also facilitate ordinary users to quickly understand the prompt information, thereby improving the efficiency of ordinary users in scanning codes.

[0125] Through the above method, in the process of instructing the scanning device to move, the moving direction of the scanning device is calculated in real time according to the image scanned during the movement of the scanning device, so as to ensure that the moving direction of the scanning device is adjusted in time during the movement of the scanning device, so that the scanning device can scan the complete code image faster.

[0126] A third prompt information for indicating the first direction is generated; the third prompt information is presented differently from the first prompt information.

[0127] It should be noted that the third prompt information in the above step can be presented at the same time as the first prompt information, or can be presented after the first prompt information is displayed for a certain period of time. Combining prompt information in various forms is conducive to better guiding the user to move the code scanning device according to the prompt information to complete the scanning of the code image.

[0128] In actual applications, after the first prompt information is generated, it is necessary to send the first prompt information to the code scanning device. At this time, the first prompt information can specifically be text information, image information, animation information or voice information, etc. In the specific implementation process, it can be set according to the actual application scenario. For example, the text prompt information can be displayed on the screen of the code scanning device while the voice prompt information is played. The text information can also be displayed on the screen of the code scanning device first. After a period of time, if the code scanning device still does not move, the voice prompt information is played. For the visually impaired, voice prompts can be selected. For the illiterate, voice, image or animation prompt information can be selected. In this regard, the embodiments of this specification do not specifically limit it.

[0129] For example, taking mobile phone code scanning payment as an example, when it is determined that the first direction of the mobile phone movement is the "upper right" direction, after the first prompt information is generated, the first prompt information can be a text message "Please move the phone to the upper right direction" displayed on the current screen of the mobile phone, or a graphic simulating the movement of the mobile phone to the upper right direction can be displayed on the current screen, or an animation guiding the user to move the mobile phone can be displayed. It also has a voice playback function, which directly plays the voice message "Please move the phone to the upper right direction".

[0130] Alternatively, the image in the scanning area of ​​the scanning device may not be the image corresponding to the target payment platform. For example, the image scanned by the scanning device is the image corresponding to payment platform A, but the application performing the scanning operation is the application corresponding to payment platform B. In this case, the following methods can be used to prompt the user:

[0131] When the first judgment result indicates that the characteristic information is inconsistent with the target characteristic information, determining an original payment platform corresponding to the characteristic information;

[0132] Generate fourth prompt information, where the fourth prompt information is used to prompt that the code image in the scanning area is the code image corresponding to the original payment platform.

[0133] When the first judgment result indicates that the characteristic information is inconsistent with the target characteristic information, and the scanning time is greater than or equal to the preset time, it jumps to the error page; the error page is used to prompt that the code image in the scanning area does not match the application performing the scanning operation.

[0134] In the above steps, when the characteristic information of the carrier layer in the scanned image is inconsistent with the target characteristic information of the carrier layer of the target payment platform, it can be determined that the image scanned by the code scanning device is not the image corresponding to the target payment platform. At this time, the original payment platform corresponding to the characteristic information of the carrier layer in the scanned image can be determined, and the name of the original payment platform corresponding to the scanned image can be generated. Of course, if the scanning time is greater than or equal to the preset time, it can also jump directly to the error reporting interface, and display the prompt information that the code image in the scanning area does not match the application performing the scanning operation on the error reporting interface. For example: when the characteristic information of the carrier layer in the scanned image is inconsistent with the target characteristic information of the carrier layer of the target payment platform, it is possible not to jump to the error reporting interface, and directly display "The current scanned image is the image of A payment, please align with the QR code of B payment" in the interface. When the first judgment result indicates that the characteristic information is inconsistent with the target characteristic information, and the scanning time is greater than or equal to the preset time, it can also jump directly to the error reporting interface, and display "The current scanned image does not match B payment" in the error reporting interface. It should be noted that the fourth prompt information here can also be one or more prompt information in text form, graphic form, and voice form.

[0135] In order to explain the method in the above embodiments in detail, the following specific implementation examples can be used for illustration:

[0136] Figure 5 It is a schematic diagram of the scanning process provided in the embodiment of this specification.

[0137] like Figure 5 As shown, suppose user X goes to merchant Y to buy goods. After the purchase, he needs to scan the code to pay. At this time, the cashier counter of merchant Y is placed with a sign for users to scan the code to pay. The sign can be attached with the payment code of payment platform A and payment platform B. The background color of the first bearing layer 501 corresponding to payment platform A is blue. The first bearing layer 501 also has corresponding text information, special identification information, and a thumbnail of payment platform A or a thumbnail of the application corresponding to payment platform A. The payment code 502 in the first bearing layer 501 is the payment code corresponding to payment platform A. The background color of the second bearing layer 503 corresponding to payment platform B is blue. The second bearing layer 503 also has corresponding text information, special identification information, and a thumbnail of payment platform B or a thumbnail of the application corresponding to payment platform B. The payment code 504 in the second bearing layer 503 is the payment code corresponding to payment platform B.

[0138] User X wants to use payment method B to make a payment. The characteristic information of the bearer layer corresponding to payment platform B is: the background color is green, the text information carries the platform name or name abbreviation of payment platform B, and has an icon thumbnail of the application corresponding to payment platform B.

[0139] When user X uses a barcode scanning device to scan the payment code on the billboard, the scanned image is the first image 505. At this time, the first image 505 includes a partial image of the first bearing layer 501 and a partial image of the second bearing layer 503. At this time, the characteristic information of the partial image of the first bearing layer 501 is determined as follows: the background color is blue, and the characteristic information of the partial image of the second bearing layer 503 is determined as follows: the background color is green, and the text information includes the platform name of the B payment platform. At this time, it can be determined that the characteristic information of the second bearing layer is consistent with the characteristic information of the target payment platform (B payment platform). Next, the position information of the partial image of the second bearing layer in the scanning area is determined, and the scanning device is instructed to move to the "upper right" direction according to the position information. After the scanning device moves, the second image 506 is scanned. The second image includes the partial image of the second bearing layer 503 and the partial image of the payment code 504. At this time, the position information of the partial image of the payment code 504 in the scanning area can be determined. According to the position information of the partial image of the payment code 504 in the scanning area, the moving direction of the scanning device is determined to be "lower left", and the scanning device is instructed to move to the "lower left" direction until the complete code image of the payment code 504 is scanned.

[0140] Through the above method, when the code scanning device fails to scan the code image or fails to scan the complete code image, the moving direction of the code scanning device can be determined based on the position information of the partial image of the carrier layer or the partial image of the code image in the scanning area, and prompt information for instructing the movement of the code scanning device is generated according to the moving direction to guide the user to scan the code image, thereby improving the success rate of the user's scanning of the code image.

[0182] Based on the same idea, the embodiments of this specification also provide a device corresponding to the above method.

[0183] Figure 7 This specification provides an embodiment corresponding to Figure 1 A schematic diagram of the structure of a prompt device during the code scanning process. Figure 7 As shown, the device 700 may include:

[0194] In the 1990s, improvements to a technology could be clearly distinguished as hardware improvements (for example, improvements to the circuit structure of diodes, transistors, switches, etc.) or software improvements (improvements to the method flow). However, with the development of technology, many improvements to the method flow today can be regarded as direct improvements to the hardware circuit structure. Designers almost always obtain the corresponding hardware circuit structure by programming the improved method flow into the hardware circuit. Therefore, it cannot be said that an improvement in a method flow cannot be implemented using a hardware entity module. For example, a programmable logic device (PLD) (such as a field programmable gate array (FPGA)) is such an integrated circuit whose logical function is determined by the user's programming of the device. Designers can "integrate" a digital system on a PLD by programming it themselves, without having to ask a chip manufacturer to design and produce a dedicated integrated circuit chip. Moreover, nowadays, instead of manually making integrated circuit chips, this kind of programming is mostly implemented by "logic compiler" software, which is similar to the software compiler used when developing and writing programs, and the original code before compilation must also be written in a specific programming language, which is called hardware description language (HDL). There is not only one HDL, but many kinds, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), Lava, Lola, MyHDL, PALASM, RHDL (Ruby Hardware Description Language), etc. The most commonly used ones are VHDL (Very-High-Speed ​​Integrated Circuit Hardware Description Language) and Verilog. Those skilled in the art should also know that it is only necessary to program the method flow slightly in the above-mentioned hardware description languages ​​and program it into the integrated circuit, and then it is easy to obtain the hardware circuit that implements the logic method flow.

[0195] The controller can be implemented in any appropriate manner, for example, the controller can take the form of a microprocessor or processor and a computer-readable medium storing a computer-readable program code (such as software or firmware) that can be executed by the (micro)processor, a logic gate, a switch, an application-specific integrated circuit (ASIC), a programmable logic controller, and an embedded microcontroller. Examples of controllers include, but are not limited to, the following microcontrollers: ARC625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320. The memory controller can also be implemented as part of the control logic of the memory. Those skilled in the art also know that in addition to implementing the controller in a purely computer-readable program code manner, the controller can be implemented in the form of a logic gate, a switch, an application-specific integrated circuit, a programmable logic controller, and an embedded microcontroller by logically programming the method steps. Therefore, this controller can be considered as a hardware component, and the devices included therein for implementing various functions can also be regarded as structures within the hardware component. Or even, the devices for implementing various functions can be regarded as both software modules for implementing the method and structures within the hardware component.
