The information coding method in the embodiment can be applied to commodity information and is arranged on a commodity outer package. For example, the information about the spraying required for the outer package of the commodity is distributed as follows:

(1) production line sequence number: 0109;

(2) and (3) commodity batch code: 6089;

(3) the production date is as follows: 20210330, respectively;

then the numerical code of the commodity information of the outer package of the commodity is: 2021033001096089.

step S120: converting N-bit numbers in the information to be coded into N conversion matrixes by utilizing the corresponding relation between the conversion matrixes and the numbers 0-9, and combining the N conversion matrixes into an information matrix; the conversion matrix adopts 10 matrixes which respectively correspond to 0-9.

The conversion matrix in the step S120 is a third-order matrix. Preferably, the matrix elements in the third order matrix have at most one 1, and the rest are 0.

In this step, the obtained numerical codes of the commodity information are filled into the basic information matrix line by line, 10 sets of third-order matrices M1, M2, M3, M4, M5, M6, M7, M8, M9, M10 are randomly generated,

Further, the definition of the transpose matrix is to convert the rows of the matrix a into corresponding columns, and the obtained new matrix is called as the transpose matrix of a, and is denoted as AT or a ', so that the first column of the matrix a is used as the first row of the transpose matrix AT or a ', and the first row of the matrix a is used as the first column of the transpose matrix AT or a '. The definition of matrix superposition, which may also be referred to as matrix addition, refers to the operation of adding together corresponding elements of two matrices.

In this step, the transposed matrix of the commodity information matrix in step S120 is acquired,

the information matrix is:

transposed matrix

Expressed as a third order matrix:

in this step, the information matrix A and the transposed matrix are combinedA^TSuperposition, by matrix operation A + A^TB, get the target matrix:

the target matrix B is represented by a third order matrix as follows:

in step S130, before the information matrix is superimposed with its transpose, the method further includes: and storing the corresponding relation between the conversion matrix and the information matrix, and decoding the target code through the corresponding relation.

Therefore, based on the superposition of the information matrix and the transposed matrix thereof, the embodiment forms symmetrical target coding information based on the symmetrical matrix data in the target matrix, thereby overcoming the defect that the whole set of information of the commodity cannot be acquired due to the loss of part of coding information in the target coding information data.

Step S140: and respectively coding each element value in the target matrix to form a plane matrix mapping dot matrix diagram to obtain the target code of the information to be coded.

In step S140, the method for separately encoding each element value in the target matrix includes:

converting the element with the value of 1 in the target matrix into a first object; converting the element with the value of 2 in the target matrix into a second object; and converting the element with the value of 0 in the target matrix into a blank area. The first object and the second object in this embodiment may be represented by different shapes of graphics, for example, the first object may be rectangular and the second object may be circular. The various figures are not limited to these, and plants and animals can be represented.

Example two

In the step, the distribution condition of the dot matrix in the plane matrix mapping dot matrix chart on the outer package of the commodity is obtained through scanning of an image recognition tool.

Step S220: judging whether the matrix mapping map is damaged or not through the restored target matrix,

when the target matrix obtained by the restoration is not damaged, the step S230 is performed; when the target matrix obtained by the restoration is damaged, the damaged target matrix is restored based on that the target matrix is a symmetric matrix, and then the process proceeds to step S230.

Step S230: and disassembling the target matrix through a preset inverse matrix operation rule, and restoring to obtain an information matrix and a transposed information matrix.

Step S240: restoring to obtain a conversion matrix sequence of the information matrix and a conversion matrix sequence of the transposed information matrix by calling a preset information matrix arrangement combination rule; and restoring to obtain the information digit sequence and the transposed information digit sequence by utilizing the corresponding rule of the conversion matrix and the decimal digits.

Step S250: and distinguishing the information digital sequence and the transposed information digital sequence by a digital identification technology to obtain decoded information, and further obtaining commodity information after the decoded information is obtained. It can be seen that the decoding process of steps S210-S250 in this embodiment is the reverse process of encoding.
