The present application provides a decoding method for a matrix two-dimensional code, where 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 present 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 present application can save resources. |
