Abstract
The present disclosure provides a method for recognizing 2D code information. A method for recognizing 2D code information according to the present disclosure, which is related to a method for recognizing 2D code information by capturing a 2D code image composed of rectangular cells, comprises obtaining a 2D code image using a mobile device equipped with a camera or an image capture device; performing a first data extraction process that identifies individual blocks storing a position pattern, an alignment pattern, and data from the obtained 2D code image; setting a first weight for removing outer blocks located outside a line connecting the position pattern and the alignment pattern with respect to a central block among the individual blocks of the 2D code image on which the first data extraction process has been performed; partitioning inner blocks located inside the position pattern and the alignment pattern among individual blocks of the 2D code image into a plurality of block groups composed of at least one or more inner blocks and setting a second weight for determining whether to select a block group according to a recognition rate of blocks constituting each block group; re…
