Step 405, obtaining a code word corresponding to the code symbol based on the coding strategy of the code symbol, and combining the code words corresponding to the code symbol to obtain a code word sequence corresponding to each image identification code.
One codeword corresponds to one code symbol, e.g., a black code symbol may correspond to codeword 1 and a white code symbol may correspond to codeword 0; the encoding strategy used in step 404 is related to the type of image identification code used, for example, when the image identification code is a two-dimensional code, a Quick Response (QR) encoding strategy is used, in which one bit of data in the target data segment can obtain an 8-bit codeword sequence based on the QR encoding strategy.
Step 406, comparing the coding symbols in the ith frame image with the coding symbols of the M regions in the (i + j) th frame image.

Wherein i is greater than or equal to 1 and less than or equal to N, j is greater than or equal to 1 and i + j is less than or equal to N, N is the number of acquired frame images, and M is an integer greater than or equal to 2.
When the comparison result represents that the coding symbol of the kth region of the ith frame image is consistent with the coding symbol of the kth region of the i + j frame image, determining the code word corresponding to the coding symbol of the kth region of the ith frame image as the code word corresponding to the coding symbol of the kth region of the i + j frame image;
when the comparison result represents that the coding symbol of the kth region of the ith frame image is inconsistent with the coding symbol of the kth region of the (i + j) th frame image, determining a code word corresponding to the coding symbol of the kth region of the (i + j) th frame image based on a coding strategy of the coding symbol;
combining the obtained code words to obtain a code word sequence corresponding to the i + j frame image; wherein the value of k is more than or equal to 1 and less than or equal to M.
Coding symbols of partial areas in two-dimensional codes of adjacent or spaced frame images (i frame image and i + j frame image) are possibly the same, and by comparing whether the coding symbols of the areas of the two frame images are the same or not, in the step 5, if the coding symbols are the same, a code word sequence of the coding symbols of the same area can be reused; the operation can be saved, and the code word sequences corresponding to the coding symbols in different areas are determined only when the code word sequences are different.
Step 408, decoding the codeword sequences corresponding to the first frame image to the nth frame image to obtain the target data
