specific Embodiment approach 1
[0043] Specific implementation mode 1. Combination Figure 1 to Figure 8 Illustrate this specific implementation mode, continuous large-capacity multi-ary barcode display method, the encoding method of each frame barcode is all the same, and the encoding method of each frame barcode is:
[0044] Step 1, the user specifies the size of the display area and the size of a single barcode; the length of the display area is M, and the width is N; the length of the barcode is Length, and the width is Width;
[0045] According to the size of the display area specified by the user and the size of a single barcode, calculate the number of barcodes m*n that can be placed, the size of the border L*Q, and the position information of each component, where m is the number of lines of the multi-ary barcode 7 , n is the number of columns of the multi-ary barcode 7, L is the length of the border, and Q is the width of the border;
[0046] Step 2: Generate a black border 1 according to the size ...
specific Embodiment approach 2
[0065] Specific embodiment two, the analytical method of continuous type large-capacity multi-ary barcode,
[0066] Step A, using camera or scanning equipment to obtain continuous large-capacity multi-ary barcodes;
[0067] Step B, performing image processing on each frame of photographs obtained by the continuous large-capacity multi-ary barcode in step A by using an imaging or scanning device;
[0068] Step C, identify the central coordinates of the three marginal positioning points and analyze the one-dimensional barcode near the lower left corner and upper right corner to obtain the serial number and data hash value; compare the two one-dimensional barcodes to determine whether the frame barcode is available, If the judgment result is no, then the frame barcode is invalid, and the decoding of the frame barcode is ended; if the judgment result is yes, proceed to the following steps;
[0069] Step D, identify the central coordinates of the internal positioning points, obtai...

Abstract
A method for display and analysis of continuous high-capacity multi-system bar codes relates to a data transmission method, and solves the problems that existing bar codes are limited in data transmission capacity, not continuous and distorted in color, and the unidirectional transmission technique is low in safety. By means of combination of a one-dimensional bar code and a multi-system bar codes and design of frames, positioning points and a color chart, continuous transmission of bar code data is realized, capacity of a one-frame bar code is increased greatly, color recovery is more accurate, accuracy and completeness of the transmitted data can be checked since the one-dimensional bar code is provided with hash value of the frame data, and safety of the data transmission technique is improved greatly. The method is applicable to data transmission.
Description
technical field [0001] The invention relates to a data transmission method. Background technique [0002] Today's society is an era of rapid information development, and every field requires continuous transmission of a large amount of data, which is also true in the field of data entry and transmission using barcode technology. Initially, one-dimensional barcodes were used to input a small amount of information, but the amount of data transmitted in this way is very small, which is far from meeting the needs of social development. Two-dimensional barcodes came into being and are widely used. Now there are multi-ary barcodes, The data capacity of barcodes is increasing. From one-dimensional barcodes to two-dimensional barcodes to multi-ary barcodes, they are all created to meet the development needs of modern society. [0003] But when it is necessary to use barcode technology to transmit a large amount of data or to continuously transmit data, because the capacity of the ...
