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.

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.

A two-dimensional barcode includes a plurality of macro modules arranged in a two-dimensional array in a spiral sequence, each of macro modules includes a predetermined number of data unit modules for storing data codewords of a predetermined binary stream of bits, a predetermined number of cluster unit modules for storing a predetermined cluster number representing a location of the macro module, and a predetermined number of rim unit modules which possess a predetermined color to form a rim of the macro module. The rim unit modules of two adjacent macro modules are contrasting with each other to enhance identification of the respective macro module.

2D coding and decoding barcode and its method thereof

The present invention relates to a scanning device with a positioning senor and a processing method to obtain images, comprising a casing, linear contact image sensor (CIS), further comprising a system processor Pfor controlling the work of said CIS by timing signal, the optical coordinate sensors and the displacement processor Pand Pfor estimating the coordinate increment () and the coordinate increment () of the real-time displacement, an A/D circuit and data buffer; said system processor Ppackets original scanning data with positioning information (), and then transfers to the upper machine. An image processing module in the upper machine de-packets said original scanning date (); Converts out the coordinate of the terminal pixel of said linear contact image sensor (CIS), and configures the image line in the object image configuring area; and calculates and rectifies the relative offset of the positioning coordinate of the two scanning bands making using of the statistical characteristic of part of pixel data in the overlapped area of the two scanning bands.

An insert-type barcode reader has a body support with an insertion slot for receiving a card with barcode. A circuit board and a CIS component module electrically connected to the circuit board with each mounted to the body support to scan and process signals. A roller is mounted to the body support for movement relative to the CIS component module to allow the card to be properly guided into the insertion slot and tightly pressed onto the CIS component for accurate scanning of the barcode on the card. Two photoelectric sensors mounted to the body support are electrically connected to the circuit board for sensing the card entering and leaving the insertion slot to control starting, running and stopping of the scanning function of the CIS component module.
