Abstract:
A graphic code processing method is provided. The method includes capturing an environment containing a graphic code, determining continuous distribution regions of pixels of a captured image in different reference directions, and identifying an overlapping region of the continuous distribution regions as a potential distribution region of the graphic code. The method also includes identifying a scanning step length from a partial image corresponding to the potential distribution region, and scanning the partial image based on the scanning step length to obtain a graphic code image. Further, the method includes performing decoding processing based on the graphic code image, until decoding succeeds and information modulated in the graphic code is obtained from the graphic code image.
