[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1

[0023] See also Figure 1 A dynamic two-dimensional code audio transmission method includes a transmitting end and a receiving end, and the method includes the following steps:

[0024] S1. The sender obtains audio data and preprocesses the audio data;

[0025] S2. The transmitter divides the preprocessed audio data into several audio data blocks of the same size, generates an audio QR code according to the audio data blocks one by one, and each audio data block corresponds to an audio QR code;

[0026] S3. The sending end displays the audio QR codes in the order in which the audio QR codes are generated, and the receiving end continuously recognizes the audio QR codes displayed by the sending end, converts each audio QR code into an audio data block, and splices all the audio data blocks into complete audio data to obtain audio data.

[0027] In an optional embodiment, in step S1, the specific implementation of the preprocessing includes: converting the sampling rate of the audio data into the same sampling rate, and compressing the audio data converted into the same sampling rate into the same format.

[0028] Convert the audio to a uniform sampling rate to facilitate the subsequent conversion of the audio data into a QR code.

[0029] In an optional embodiment, in step S2, after the transmitting end divides the pre-processed audio data into a plurality of audio data blocks of the same size, the method further includes: converting each audio data block into a binary format.

[0030] Specifically, the audio data is divided into a number of audio data blocks of 1 Kb in size, and the audio data is converted into a binary bit stream that is convenient for generating a two-dimensional code through binary conversion.

[0031] In an optional embodiment, in step S2, after converting each audio data block into a binary format, the method further includes generating an error correction code for each audio data block and inserting the error correction code into the audio data block.

[0032] Specifically, for each audio data block, a corresponding Reed-Solomon error correction code is calculated according to each audio data block, and the error correction code is converted into binary data, and the binary error correction code is inserted into the end of the audio data block to obtain a binary audio data block with the error correction code.

[0033] In an optional embodiment, in step S2, the audio QR code is generated one by one according to the audio data blocks, and its specific implementation method includes: for each audio data block, starting from the starting position of the audio data block, each two binary digits are a group, and each group of digits corresponds to a point position of the QR code to generate an audio QR code.

[0034] The two-dimensional code is a square image, which includes a number of points. The audio data block is converted into a binary bit stream, which is rendered using the corresponding point positions of the binary bit stream, and the binary bit stream is converted into a two-dimensional code according to the generation method of the two-dimensional code.

[0035] In an optional embodiment, in step S2, each group of numbers corresponds to a point, and its specific implementation method includes: each group of numbers includes multiple number combinations, each number combination corresponds to a color, and the color of the point corresponding to each group of numbers is the same as the color corresponding to the number combination of the group of numbers.

[0036] In a specific embodiment, for each point, there is: the number 00 combination corresponds to black, the number 01 combination corresponds to red, the number 10 combination corresponds to green, and the number 11 combination corresponds to blue. Different number combinations correspond to different colors, so the QR code is rendered according to different combinations. Moreover, the QR code is rendered in different colors rather than black and white, so that the subsequent receiving end can detect and identify the QR code, thereby better reading the audio information in the QR code and improving the recognition accuracy.

[0037] In an optional embodiment, in step S2, generating the audio QR code one by one according to the audio data blocks further includes: inserting a preset pattern at a preset position of the corresponding generated audio QR code according to the position of the audio data block in the audio data.

[0038] The preset pattern includes: a polygon or a special symbol; specifically, a preset pattern is inserted into the four corners of the non-data point of the two-dimensional code for positioning; when the audio data block corresponding to the audio two-dimensional code is the first audio data block of the audio data, an '@' symbol is inserted into one of the four corners of the audio two-dimensional code; when the audio data block corresponding to the audio two-dimensional code is the last audio data block of the audio data, a '#' symbol is inserted into one of the four corners of the audio two-dimensional code; by inserting special symbols or patterns, the receiving end can locate the starting or ending position of the data, thereby improving data transmission efficiency.

[0039] In an optional embodiment, in step S2, generating the audio QR code one by one according to the audio data blocks further includes: adding a timestamp of the generation time to the audio QR code each time the audio QR code is generated.

[0040] By adding a timestamp, the receiving end can confirm the order of the audio QR codes and sort the corresponding audio data blocks according to the timestamp to obtain correct and complete audio data.

[0041] In an optional embodiment, in step S3, the transmitting end displays the audio QR code in the order in which the audio QR code is generated, and the specific implementation method includes: displaying one or more audio QR codes simultaneously in the audio order, and each audio QR code is not displayed repeatedly.

[0042] Improve audio transmission efficiency by displaying multiple QR codes at the same time.

[0043] In an optional embodiment, the receiving end continuously scans the displayed QR code through a camera, and when the displayed QR code changes, identifies the displayed QR code and converts it into a binary bit stream according to the color mapping relationship of each point.

[0044] In an optional embodiment, after the receiving end recognizes and parses an audio QR code, the audio data block is verified according to the Reed-Solomon error correction code to confirm whether there are problems such as data loss or omission. If the verification fails, the audio data block is requested again from the sending end to ensure that the audio data can be transmitted intact, so as to avoid audio damage caused by data loss during transmission.

[0046] See also Figure 2 , a dynamic two-dimensional code audio transmission system, comprising:

[0047] The audio processing module is used for the sending end to obtain audio data and pre-process the audio data;

[0048] A QR code generation module is used for the sending end to divide the pre-processed audio data into a number of audio data blocks of the same size, and generate audio QR codes according to the audio data blocks one by one, each audio data block corresponding to an audio QR code;

[0049] The audio transmission module is used to enable the sending end to display the audio QR code in the order in which the audio QR code is generated. The receiving end continuously recognizes the audio QR code displayed by the sending end, converts each audio QR code into an audio data block, and splices all audio data blocks into complete audio data to obtain audio data.
