A two-dimensional dot matrix barcode encoding method comprises: forming a plurality of coordinate calibration blocks, a plurality of data storage blocks, a first indication block and a second indication block respectively by filling code points into the virtual code point storage blocks, wherein the first indication block and the plurality of coordinate calibration blocks are filled with a code point located in the center of the virtual code point storage blocks; and forming, by means of a combination of the first indication block and the second indication block, a direction and coordinate indication set indicative of a direction and a coordinate, wherein the second indication block is not filled with a code point or is filled, in the center thereof, with an ink code point capable of reflecting a light having a specific wavelength, and the plurality of coordinate calibration blocks are separated from each other.

Two-dimensional dot matrix barcode encoding and identifying methods

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&#x2265;4, N&#x2265;4, N&#x2265;4, and M and N are both even numbers.

Two-dimensional dot matrix barcode encoding and reading methods

The application provides a decoding method for a matrix two-dimensional code, wherein a matrix two-dimensional code image to be decoded is a code array of jointed matrix two-dimensional code symbols, formed by multiple identical unit code patterns; an image obtained by scanning does not need to include a complete unit code pattern, and a decoding process of the image is: obtaining a binary image of a to-be-decoded code array of jointed matrix two-dimensional code symbols, locating each data point in a unit code pattern that the data point belongs to, so as to restore a complete unit code pattern, and then performing decoding. The application only needs an area twice the area of a unit code pattern even if decoding is performed when the code pattern is rotated by a most severe degree. In addition, the application can save resources.

Decoding method for matrix two-dimensional code

An identifier assigning method, an identifier parsing method, and a multimedia reading are provided. The identifier assigning method includes: obtaining association information between at least two objects with different expression forms (), where the at least two objects with different expression forms have the same subject content; assigning association relationship unique identifiers to the at least two objects with different expression forms according to the association information (), where the association relationship unique identifier is used to show a unique association relationship among different expression forms with the same subject content, the unique association refers to a unique identifier of an association relationship among various expression forms with different subject content, and the association relationship unique identifiers in each group are globally unique. The method realize a synchronized function demonstration of combined multimedia information, and manage combined multimedia content using the identifier.

Identifier assigning method, identifier parsing method, and multimedia reading

The invention discloses a two-dimensional code and its decoding method and the printing publication for applying the two-dimensional code. Positioning dots located at four corners of code symbols in the two-dimensional code are larger than data dots. The code symbols are arranged repeatedly on the basement, including at least two identical code symbols. Adjacent code symbols share same positioning dots on their adjacent border. The decoding method comprises the following steps: reading the two-dimensional code by using a reading device, detecting the margin of each dot, obtaining an image of the closed border, selecting positioning dots; matching the positioning dots in a rectangle mode, grouping the data dots, reconstructing a matrix of data dots, and reducing codes according to an inverse process of codes layout in coding process of the two-dimensional code.
