specific Embodiment approach 1

[0025] Specific implementation mode 1. Combination figure 1 , 2 , 10, 11 and 12 illustrate this embodiment, a kind of coding method of continuous type multi-ary system bar code, and the coding method of its continuous type multi-ary system bar code is:

[0026] Step 1. Using the existing barcode standard, the original data is barcode encoded to obtain the encoded binary matrix;

[0027] Step 2, a plurality of binary matrices of the same size obtained in step 1 are fused into a matrix by means of element alignment;

[0028] Step 3: Combining the matrix in step 2 and the resolution capability of the barcode reading device to create a color mapping table. When the barcode reading equipment can only recognize grayscale colors, the color values ​​in the color table can only take values ​​within the recognizable grayscale range; Values ​​within the recognized color range.

[0029] Step 4, assign corresponding colors to each element of the matrix obtained in step 2 by looking up ...

Abstract

The invention discloses a coding method and a decoding method for a continuous multi-system bar code, which relate to a data transmission method and aim to improve the data capacity of the bar code. The coding method comprises the following steps: combining with a traditional bar code standard, carrying out multi-system bar code coding to the original data with a method of fusing a plurality of planes; respectively setting two same one-dimensional serial number bar codes above and below the original data; and sending the one-dimensional serial number bar codes to a channel. The decoding method comprises the following steps: firstly, carrying out one-dimensional bar code identification decoding by a receiving end; judging whether the serial numbers of the two one-dimensional bar codes are repeated or not; and after the operation of judging whether the serial numbers of the bar codes are successfully decoded is carried out, carrying out corresponding data reading, storing and finishing decoding. The coding method and the decoding method for the continuous multi-system bar code are suitable for coding and decoding the bar code.

Description

technical field [0001] The invention relates to a barcode encoding method and a decoding method thereof. Background technique [0002] At present, one-dimensional barcodes are widely used, but the data capacity is too small and the types of encoded data are limited. Two-dimensional barcodes have the advantages of large information capacity, wide coding range, high reliability, strong fault tolerance, and can represent Chinese characters and image information, etc., which solve the defects of one-dimensional barcodes to a certain extent. However, the coding capacity of conventional two-dimensional barcodes cannot meet the requirements in some specific application scenarios, and it cannot perform continuous transmission of large amounts of data, and cannot be directly converted into multi-ary barcodes. Contents of the invention [0003] The purpose of the invention is to improve the data capacity of the barcode, thereby providing a decoding method of the continuous multi-ar...
