Abstract

Two-dimensional Dot Matrix Barcode Encoding and Identifying Methods Disclosed are two-dimensional dot matrix barcode encoding and identifying methods. A two-dimensional dot matrix barcode is composed of M×N virtual code point storage blocks. The 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 and distributed among the two-dimensional dot matrix barcode. The present invention has the advantages of having a large encoding capacity and small interference to human vision, and being simple and reliable to identify. Figure 8
