Embodiment Construction

[0040] The success rate of QR code parsing is inversely proportional to the number of times the QR code parsing process is executed. That is to say, for a certain two-dimensional code, the more attempts to analyze the two-dimensional code, the lower the success rate of the two-dimensional code analysis.

[0041] In a QR code analysis process, there are two main factors that affect the success rate of QR code analysis:

[0042] 1. Whether the selected binarization algorithm is appropriate. In practice, because the same QR code is often different in different environments in the carrier attached to it, the lighting conditions, etc., therefore, there will be significant differences in the QR code images captured for the same QR code in different environments. difference. For example, the QR code image captured in a strong light environment is often whitened due to overexposure, and it is usually suitable to use a local adaptive binarization algorithm. This means that in order ...

Abstract

Disclosed are a two-dimensional code analysis method and device. In a single two-dimensional code analysis process, a binarization algorithm having a highest selection evaluation score is selected as a target algorithm and used to perform binarization processing on a current captured image of a two-dimensional code so as to obtain a black and white image of the two-dimensional code. If subsequent recognition of the black and white image of the two-dimensional code fails, the selection evaluation score corresponding to the target algorithm is redetermined according to the binarization result quality of the binarized black and white image. The better the binarization result of the binarized black and white image of the two-dimensional code, the higher the readjusted selection evaluation score of the corresponding target algorithm.

Description

technical field [0001] The embodiments of this specification relate to the field of information technology, and in particular to a two-dimensional code analysis method and device. Background technique [0002] At present, as an information carrier, two-dimensional codes are widely used in various industries. For example, in the field of mobile payment, the payer can use a code scanning device such as a mobile phone to analyze the account information of the payee from the QR code provided by the payee, so that the payee can pay the payee online. [0003] The process of parsing the QR code mainly includes the following steps: [0004] 1. Scan the QR code to capture a frame of QR code image. [0005] 2. Randomly select a binarization algorithm from at least two preset binarization algorithms, and use the randomly selected binarization algorithm to binarize the captured QR code image to obtain a black and white image of the QR code . [0006] 3. Recognize the black-and-white...
