Abstract:
A two-dimensional dot matrix barcode encoding method comprises: forming a plurality of coordinate calibration blocks, a plurality of data storage blocks and a direction indication block by filling code points into the virtual code point storage blocks, wherein the plurality of coordinate calibration blocks are filled with only one code point located in the center of the virtual code point storage block; the direction indication block is filled with at least two code points, only one code point being located in the center of the virtual code point storage block; the plurality of coordinate calibration blocks and the direction indication block are separated from each other and distributed among the plurality of data storage blocks; and code points filled in the plurality of data storage blocks are used to store data information, where M≥4, N≥4, N≥4, and M and N are both even numbers.

Claim (Index 5):
A two-dimensional dot matrix barcode reading method, used for identifying a two-dimensional dot matrix barcode obtained by the two-dimensional dot matrix barcode encoding method according to  claim 1 , the two-dimensional dot matrix barcode reading method comprising the following steps:\n acquiring a barcode grayscale image not smaller than the size of a two-dimensional dot matrix barcode, the grayscale image comprising at least one direction indication block and a plurality of coordinate calibration blocks; acquiring row and column positions of the coordinate calibration blocks and the direction indication block in the two-dimensional dot matrix barcode according to the grayscale image comprising the at least one direction indication block and the plurality of coordinate calibration blocks; and reading data stored in the two-dimensional dot matrix barcode according to the grayscale image and the row and column positions of the coordinate calibration blocks and the direction indication block.
