The electronic terminal can circularly display the N two-dimensional code images according to a preset display refresh rate. Because the arrangement density of the color blocks of the single two-dimensional code image is predetermined according to the precision of the two-dimensional code acquisition equipment, even if the precision of the two-dimensional code acquisition equipment is low, each complete two-dimensional code image can be acquired, and the accuracy of the two-dimensional code image is improved. Therefore, the two-dimensional code reading device can obtain the to-be-transmitted data with a large data size according to the two-dimensional code images acquired by the two-dimensional code acquisition device.

[0002] Due to its advantages of large information capacity, strong fault tolerance and low cost, QR codes are widely used in many fields such as logistics management, document management, and information transmission. The QR code image is collected by a QR code collection device such as a camera, and the collected QR code image is detected and identified by a QR code reading device, so that the information carried by the QR code image can be obtained and information transmission can be realized. It can be understood that the greater the amount of information carried by the QR code image, the higher the density of its color block arrangement, the higher the accuracy required by the QR code collection device, and the higher the cost of the QR code collection device.

Therefore, low-density QR codes are often used for information transmission in the field of security attendance, and the amount of information transmitted is limited.

[0059] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0060] In one embodiment, the QR code generation method and QR code reading method of the present application can be applied to Figure 1 the application environment shown. Among them, the electronic terminal 102 refers to an electronic device that can be used to refresh and display a QR code graphic, which can be but is not limited to a smart phone, a tablet computer, a wearable device, etc. The QR code acquisition device 104 refers to a device used to acquire a QR code image, such as a camera device. The QR code reading device 106 refers to a device that can read data from a QR code image, such as a notebook computer, a desktop computer, a server, etc.

[0061] In the process of data transmission based on the QR code, the electronic terminal 102 can generate a QR code image according to the data to be transmitted and display it to the QR code acquisition device 104. The QR code acquisition device 104 can acquire the QR code image displayed in the electronic terminal according to the accuracy of this device to obtain a target QR code image. The QR code reading device 106 can obtain the target QR code image acquired by the QR code acquisition device 104 and identify and decode the QR code in the target QR code image to obtain the data carried in the target QR code image. In this way, data transmission can be realized between the electronic terminal 102 and the QR code reading device 106 through the QR code.

[0062] It should be noted that in the present application, the QR code acquisition device and the QR code reading device can be two independent devices or integrated into one. When the QR code acquisition device and the QR code reading device are integrated into one, the integrated device can have the functions of QR code acquisition and QR code reading.

[0063] In one embodiment, the present application provides a QR code generation method, which can be applied to Figure 1 the electronic terminal shown. As Figure 2 shown, the QR code generation method includes the following steps:

[0064] S202: Obtain the data to be transmitted and the screen size data of the electronic terminal.

[0065] Among them, the data to be transmitted refers to the data that needs to be transmitted between the electronic terminal and the QR code reading device, which can be determined according to the actual situation and is not specifically limited in this article. For example, the data to be transmitted can be face data, fingerprint data, palmprint data, palm vein data, finger vein data, hand shape data, retina data, iris data, voice data, etc.

[0066] The screen size data of the electronic terminal can be the area size of the displayable area in the electronic terminal screen. For example, the screen size data can include any one or any combination of data such as the length, width, and diagonal length of the displayable area.

[0067] In this step, the electronic terminal can obtain the data to be transmitted and the screen size data of this device. It can be understood that the acquisition method of the screen size data can be determined according to the situation. In one example, the acquisition steps of the screen size data of the electronic terminal can include the following sub-steps:

[0068] Step A1: Obtain the screen DPI and screen resolution of the electronic terminal respectively;

[0069] Step A3: Determine the screen size data according to the screen DPI and screen resolution.

[0070] Among them, the screen DPI (dots per inch, the number of pixels displayed per inch) can be used to reflect the pixel density of the electronic terminal screen. The screen resolution refers to the number of pixels displayed on the screen, which can be expressed as the number of pixels in the horizontal direction × the number of pixels in the vertical direction. Based on this, this application can calculate the screen size data of the electronic terminal based on the pixel density and the number of pixels to achieve automatic acquisition of the screen size.

[0071] S204: Determine the data volume carried by the QR code according to the screen size data and the color block arrangement density; among them, the color block arrangement density is determined in advance according to the accuracy of the QR code acquisition device.

[0072] It can be understood that the QR code image is formed by arranging specific geometric figures in a certain pattern on a plane. A geometric figure is filled with one color to form a color block. In other words, the QR code pattern is formed by arranging multiple color blocks in a certain pattern. The color block arrangement density in this application refers to the number of color blocks per unit length, which can be used to determine the size of a single color block. It can be understood that the higher the color block arrangement density, the smaller the size of a single color block; the lower the color block arrangement density, the larger the size of a single color block. When the size of the QR code image remains unchanged, the higher the color block arrangement density, the larger the data volume that the QR code image can carry; on the contrary, the lower the color block arrangement density, the smaller the data volume that the QR code image can carry.

[0073] In this step, the electronic terminal can preset the color block arrangement density in advance, which is determined according to the accuracy of the two-dimensional code acquisition device. The accuracy of the two-dimensional code acquisition device can be determined by parameters such as the resolution and / or sensor size of the two-dimensional code acquisition device, and this is not specifically limited in this article.

[0074] The electronic terminal can determine the data volume that can be carried by a single two-dimensional code adapted to the two-dimensional code acquisition device, that is, the two-dimensional code data volume, based on the screen size data of the electronic terminal and the preset color block arrangement density.

[0075] S206: Calculate the number of two-dimensional code splits based on the two-dimensional code data volume and the total data volume of the data to be transmitted.

[0076] In this step, after determining the data volume that can be carried by a single two-dimensional code, the number of two-dimensional code splits N can be calculated according to the total data volume of the data to be transmitted and the two-dimensional code data volume. For example, the ratio of the total data volume of the data to be transmitted to the two-dimensional code data volume can be calculated, and the ceiling function is applied to this ratio, and the resulting integer is the number of two-dimensional code splits.

[0077] In an example, since the acquisition of the two-dimensional code image is affected by factors such as illumination and display angle, the number of two-dimensional code splits calculated by the electronic terminal may not be conducive to the two-dimensional code acquisition device to acquire a complete two-dimensional code image. Therefore, the electronic terminal can obtain the number input by the user and use the number input by the user as the number of two-dimensional code splits to support the manual setting function.

[0078] S208: Split the data to be transmitted into N data segments, and generate N two-dimensional code images corresponding to the N data segments one by one; where N is the number of two-dimensional code splits.

[0079] In this step, when the number of two-dimensional code splits N is determined, the electronic terminal can split the data to be transmitted into N data segments, and generate a two-dimensional code image for each data segment respectively. For example, when N = 2, the electronic terminal can generate the first two-dimensional code image according to one of the data segments, and generate the second two-dimensional code image according to the other data segment.

[0080] S210: Display the N two-dimensional code images in a loop according to the preset display refresh rate.

[0081] In this step, the display refresh rate can be a value manually set by the user or a default value. The electronic terminal can display the N two-dimensional code images in a loop according to the preset display refresh rate. For example, when the display refresh rate is 1 image per second and N = 3, the electronic terminal can display 3 two-dimensional code images in a loop, and each two-dimensional code image is continuously displayed for 1 second each time.

[0082] It is understandable that when the display refresh rate is too high, the QR code acquisition device may repeatedly acquire the same QR code image, causing it to consume more time to acquire N QR code images, reducing the subsequent QR code reading efficiency. To improve the QR code reading efficiency, in one example, the display refresh rate can be 3 QR code images per second.

[0083] In this embodiment, in the process of generating a two-dimensional code, the amount of data carried by the two-dimensional code of a single two-dimensional code can be determined according to the screen size data of the electronic terminal and the preset color block arrangement density, and the data to be transmitted with a larger amount of data can be split into N data fragments with smaller amounts of data, and a two-dimensional code image is generated for each data fragment. The electronic terminal can display N two-dimensional code images in a loop according to the preset display refresh rate. Since the color block arrangement density of a single two-dimensional code image is predetermined according to the accuracy of the two-dimensional code acquisition device, even if the accuracy of the two-dimensional code acquisition device is low, a complete two-dimensional code image can be acquired, so that the two-dimensional code reading device can obtain a large amount of data to be transmitted according to each two-dimensional code image. It can be seen that the present application can simultaneously achieve low-cost and large-volume information transmission.

[0084] In one embodiment, N two-dimensional code images are generated according to the N data fragments in a one-to-one correspondence, including:

[0085] Step B1: Obtain the total package identifier corresponding to the data to be transmitted;

[0086] Step B3: For each data fragment, determine the splitting sequence number of the data fragment in the data to be transmitted, and generate splitting package data according to the total package identifier, splitting sequence number, number of QR code splits and the data fragment in accordance with the preset splitting package generation protocol, and generate the QR code image corresponding to the data fragment based on the splitting package data.

[0087] The total package identifier of the data to be transmitted may be the data identifier corresponding to the data to be transmitted, which is used to distinguish different data to be transmitted. For example, the total package identifier corresponding to the data to be transmitted A may be identifier A, and the total package identifier corresponding to the data to be transmitted B may be identifier B, and A is different from B.

[0088] In the process of generating a two-dimensional code image, the electronic terminal may first determine the splitting sequence number of the data segment used to generate the two-dimensional code image in the data to be transmitted, and the splitting sequence number may be used to indicate the data position of the data segment in the data to be transmitted. Then, the electronic terminal may generate splitting packet data according to a preset splitting packet generation protocol, so that the splitting data packet may include the total package identifier corresponding to the data to be transmitted, the splitting sequence number corresponding to the data segment, the number of two-dimensional code splits, and the specific data of the data segment, so that the two-dimensional code reading device can determine whether the received data has been split based on the data in the splitting data packet and determine how to splice the data.

[0089] It can be understood that the split packet generation protocol can be determined according to the actual situation, and this application does not make specific restrictions on this. In one example, this application can adopt the split packet generation protocol shown in Table 1:

[0090] Table 1

[0091]

[0092] After obtaining the split packet data, the electronic terminal can generate a two-dimensional code image corresponding to the data segment according to the split packet data.

[0093] In one embodiment, generating the two-dimensional code image corresponding to the data segment based on the split packet data includes:

[0094] Step B31: Obtain registration verification information and generate registration verification packet data according to the registration verification information;

[0095] Step B33: For each data segment, perform CRC check on the registration verification packet data and the split packet data to obtain check data, and according to the preset total data protocol, generate an image data packet based on the registration verification packet data, the split packet data, and the check data, and generate a two-dimensional code image based on the image data packet.

[0096] Among them, the registration verification information can be, but is not limited to, digital card numbers, Weigang card numbers, verification template information, registration template information, multi-type information combinations, etc. in the field of security attendance.

[0097] In this embodiment, to ensure the integrity and correctness of the data, this application can perform CRC (Cyclic Redundancy Check) check according to the registration verification data and the split packet data, and generate an image data packet according to the preset total data protocol, so that the image data packet can include the registration verification packet data, the split packet data, and the check data.

[0098] It can be understood that the total data protocol can be determined according to the actual situation, and this application does not make specific restrictions on this. In one example, this application can adopt the total data protocol shown in Table 2:

[0099] Table 2

[0100]

[0101] In one embodiment, this application provides a two-dimensional code reading method, which can be applied to Figure 1 the two-dimensional code reading device shown. As Figure 3 shown, the two-dimensional code reading method of this application can include the following steps:

[0102] S302: Obtain the target QR code image and perform QR code recognition on the target QR code image; wherein, the target QR code image is generated according to the QR code generation method of any of the above embodiments.

[0103] Wherein, the target QR code image can be an image obtained by a QR code acquisition device collecting the QR code image displayed on an electronic terminal, and the electronic terminal can generate the QR code image it displays based on the QR code generation method of any of the above embodiments.

[0104] In this step, the QR code reading device can obtain the target QR code image collected by the QR code acquisition device and perform QR code recognition on the target QR code image to attempt to obtain the data packet carried by the target QR code image.

[0105] Further, in an example, before performing QR code recognition on the target QR code image, a QR code detection algorithm can be used to detect the QR code on the target QR code image to determine the QR code area in the target QR code image, and thus judge whether the target QR code image includes a recognizable QR code. If the target QR code image includes a recognizable QR code, QR code recognition can be performed based on the QR code area.

[0106] S304: If the recognition is successful, obtain the target data segment according to the QR code recognition result of the target QR code image.

[0107] In this step, if the QR code recognition is successful, it indicates that the target QR code image includes a recognizable QR code, and the QR code reading device has obtained the data packet carried by the QR code. In this case, the QR code reading device can obtain the target data segment carried by the target QR code image according to the QR code recognition result.

[0108] S306: Obtain the target received data according to the target data segment.

[0109] In this step, the QR code reading device can obtain the complete target received data based on at least one target data segment to realize data transmission between the electronic terminal and the QR code reading device.

[0110] In one embodiment, the QR code recognition result includes a target total packet identifier, the number of target QR code splits, the target data segment, and the split sequence number corresponding to the target data segment. Among them, the target total packet identifier can be the total packet identifier corresponding to the target data segment, and the number of target QR code splits can be the number of QR code splits corresponding to the target data segment.

[0111] Obtaining the target received data according to the target data segment includes:

[0112] Step C1: Based on the number of splits of the target QR code, the target overall package identifier, and each cached data, determine whether all data segments of the target received data have been obtained;

[0113] Step C3: If all data segments of the target received data have been obtained, then based on the split serial number corresponding to the target data segment and the split serial numbers corresponding to each cached data, splice the target data segment and each cached data, and obtain the target received data;

[0114] Step C5: If all data segments of the target received data have not been obtained, then cache the target overall package identifier, the target data segment, and the split serial number corresponding to the target data segment.

[0115] In this embodiment, after obtaining the target data segment carried by the target QR code image, the QR code reading device can, according to the number of splits of the QR code corresponding to the target data segment, determine whether the target data segment is split data. If so, the QR code reading device can, according to the overall package identifier corresponding to the target data segment and each cached data in the QR code reading device, determine whether the QR code reading device has read all data segments of the target received data.

[0116] If all data segments of the target received data have been read, then the QR code reading device can, according to the split serial numbers corresponding to each data segment, splice each data segment corresponding to the target received data in sequence to obtain the complete target received data. Further, in an example, if the target received data includes verification information, the verification information can be used to verify the spliced target received data to ensure data integrity and consistency, and push the target received data to the corresponding application when the verification passes.

[0117] If all data segments of the target received data have not been obtained, that is, at least one data segment corresponding to the target received data is missing, then the target data segment and the split serial number corresponding to the target data segment can be cached for subsequent data splicing.

[0118] In one embodiment, the QR code reading method of the present application may further include the following steps:

[0119] Step D1: If the recognition is unsuccessful, calculate the image resolution of the target QR code image;

[0120] Step D3: If the image resolution is greater than a preset pixel upper limit value, generate a first suggestion message; the first suggestion message is used to prompt the user of the target electronic terminal to move the target electronic terminal away from the QR code acquisition device; the QR code acquisition device is a device for acquiring the target QR code image, and the target electronic terminal is an electronic terminal for displaying the target QR code image;

[0121] Step D5: if the image resolution is less than the preset pixel lower limit, generating second suggestion information; the second suggestion information is used to prompt the user to bring the target electronic terminal close to the two-dimensional code acquisition device;

[0122] Step D7: Push the first suggestion information or the second suggestion information to the target electronic terminal.

[0123] In this embodiment, when the electronic terminal is too close or too far from the two-dimensional code acquisition device, the two-dimensional code reading device may not be able to successfully identify the data carried by the target two-dimensional code image. Therefore, in the case of failure in two-dimensional code recognition, the two-dimensional code reading device can calculate the image resolution of the target two-dimensional code image, and judge whether the target electronic terminal is too close or too far from the two-dimensional code acquisition device based on this, and trigger the interaction mechanism.

[0124] If the image resolution is greater than the preset pixel upper limit, it indicates that the target electronic terminal is too close to the two-dimensional code acquisition device. Therefore, the two-dimensional code reading device can generate a first suggestion message to prompt the user to move the target electronic terminal away from the two-dimensional code acquisition device.

[0125] If the image resolution is less than the preset pixel lower limit, it indicates that the target electronic terminal is too far away from the two-dimensional code acquisition device. Therefore, the two-dimensional code reading device can generate second suggestion information to prompt the user to move the target electronic terminal closer to the two-dimensional code acquisition device.

[0126] In this way, the success rate of QR code recognition can be further improved, thereby improving the reliability of data transmission.

[0127] The following is a description of a two-dimensional code generating device provided in an embodiment of the present application. The two-dimensional code generating device described below and the two-dimensional code generating method described above can be referenced to each other.
