Title:
QUICK RESPONSE CODE GENERATION METHOD AND APPARATUS, QUICK RESPONSE CODE DECODING METHOD AND APPARATUS, AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/199471
Kind Code:
A1
Abstract:
The embodiments of the description disclose a quick response code generation method and apparatus, a quick response code decoding method and apparatus, and a device. The quick response code generation method comprises: acquiring a quick response code, a quick response code image of which is to be generated; performing error-resilient coding by using a coding algorithm with a preset error-resilient rate, so as to obtain a quick response code that has been subjected to error-resilient processing; determining a code element shape, in a generation area for the quick response code image, corresponding to each data information bit of the quick response code that has been subjected to the error-resilient processing; according to a preset quick response code arrangement rule, determining first position information, in the generation area, corresponding to each data information bit of the quick response code that has been subjected to the error-resilient processing; determining second position information of each positioning point in the generation area; and then generating the quick response code image on the basis of the first position information, the code element shape corresponding to each data information bit, and the second position information of each positioning point.
