Description

technical field [0001] The invention relates to the field of two-dimensional code decoding algorithms, in particular to a verification method based on a two-dimensional code algorithm comparison verification system. Background technique [0002] For the newly developed two-dimensional code decoding algorithm, in order to verify the decoding ability of the two-dimensional code decoding algorithm, and compare it with the decoding ability of other two-dimensional code decoding algorithms. It is determined whether the decoding ability of the two-dimensional code decoding algorithm developed first is strong, inferior or the same as that of the existing barcode scanning guns in the market. [0003] Existing comparative verification usually uses two decoding algorithms to perform decoding in a manual manner, and then compares the decoding results. It has the technical problems of low accuracy of comparison results and complex and cumbersome methods due to inconsistent decoding con...
