Abstract

The invention discloses a two-dimensional code image processing method and device. The method comprises the following steps: identifying a specified shape contained in a two-dimensional code from a two-dimensional code image; determining the size of a code particle in the two-dimensional code image according to the specified shape; dividing grids in the two-dimensional code image by taking the size of the code particle as a grid reference; and generating a standard two-dimensional code according to the image content in each grid. According to the technical scheme, the standard two-dimensional code is reconstructed based on the two-dimensional code image by utilizing the characteristic that the two-dimensional code is composed of the code particles, and the determined size of the code particle is more accurate by utilizing special specified shapes such as a Chinese character 'hui' shape in the two-dimensional code image, so that the reconstruction accuracy of the standard two-dimensional code is improved, and the subsequent analysis accuracy of the two-dimensional code is improved.

Description

technical field [0001] The present application relates to the field of image processing, in particular to a two-dimensional code image processing method and device. Background technique [0002] A two-dimensional code refers to a black and white graphic that records data symbol information distributed on a plane with a certain specific geometric figure according to a certain rule. Analyzing the two-dimensional code can obtain the recorded data symbol information. The two-dimensional code analysis method in the prior art usually obtains the two-dimensional code image through the camera first, and then uses the analysis library to complete the two-dimensional code analysis. However, when the size of the two-dimensional code is small, or the two-dimensional code is worn, the success rate of parsing the two-dimensional code image is not high. Contents of the invention [0003] The embodiments of the present application provide a two-dimensional code image processing method an...
