Abstract

20 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 5 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 patternthatthedatapointbelongsto,soastorestoreacompleteunitcodepattern,andthen 10 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.
