A kind of coding of dot matrix Quick Response Code and recognition methods

The invention discloses a kind of coding of dot matrix Quick Response Code and recognition methods, the dot matrix Quick Response Code is made of M × N number of virtual code-point memory block, and multiple coordinates correction blocks, multiple data storage area blocks, a first instruction block and one second instruction block are respectively formed by filling code-point in the virtual code-point memory block；In the first instruction block and the multiple coordinates correction block the code-point filled be respectively positioned on virtual code-point memory block center and only there are one；It combines to form direction and coordinate instruction district's groups with direction and coordinate indicative function by the first instruction block and the second instruction block；It is not filled by the ink code-point of code-point or center filled with reflection special wavelength light in the second instruction block；The multiple coordinates correction block is spaced from each other, and is distributed in the dot matrix Quick Response Code.The present invention have many advantages, such as code capacity it is big, it is small to the vision interference of human eye, identification can be simply and reliably.
