Method for generating beautified two-dimensional code

The invention discloses a method for generating a beautified two-dimensional code. A code word distribution map is generated according to an RS block in the two-dimensional code structure and the code word distribution characteristic of the RF block; a significance detection technology is utilized to detect a region of interest in a background picture to generate a significance graph; the code word distribution map is combined with the significance graph to calculate the significance value of each code word block, a code word order table is generated according to the significance values, m frontmost code cords are selected to form a replaceable region based on a redundancy principle of a error correction coding mechanism, and the rest part serves as a non-replaceable region; background images of code word modules in the replaceable region are directly replaced; and modules in the non-replaceable region are replaced in the threshold-based layered replacement rule. In addition, The shape of a URL of a dual rectangular shape in the function region is transformed. Thus, content of the two-dimensional code is more diverse and interesting, the two-dimensional code is more customized, and the visual effect of the appearance of the two-dimensional code is improved.
