Problems solved by technology

The BM algorithm is a limited-distance decoding algorithm with poor error correction and decoding capabilities, which limits the recognition ability of the existing two-dimensional code decoding technology. Enter information

Moreover, the decoding performance of the BM algorithm is poor, and the anti-noise ability is poor, which makes the recognition speed of the existing two-dimensional code decoding technology slow, especially when the two-dimensional code is detached, stained, perforated, and partially damaged.
