Abstract: 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.

Abstract: This present invention discloses one type of two-dimensional bar code and its encoding and decoding method. The two-dimensional bar code is represented as circular element modules (CEMs), between which there are spaces. As a CEM remains a CEM after deep defocusing imaging, it can be restored well to be the same shape as that of a CEM after the filtering by the Unsharp Mask. This design enables the image processing algorithm to become insensitive to the selection of the binarization threshold value. Since there is space between modules, it is less likely that the adjacent modules will stick together after binarization so that each module can be positioned independently. The present invention is very reliable for reading and decoding even under imaging conditions of deep defocusing and low illumination. Its features include easy-to-read, strong error correction capability and low requirement for reading devices, which makes it a potential popular application.
