[0021] The recognition method for voice broadcast of logistics commodity information based on color two-dimensional code technology includes three modules: color two-dimensional code image encoding, color two-dimensional code image collection, preprocessing and decoding, and voice broadcast information. The first module is a two-dimensional code image generation module; the second module is a color two-dimensional code image acquisition and decoding module, including three image acquisition methods: scanning, photographing and loading local images. The decoding includes preprocessing. Extraction and correction, data sampling grid and error correction in decoding, etc.; The third module is the voice broadcast information module. In this process, the collected two-dimensional code symbol image is preprocessed and decoded If the audio information obtained by decoding the information is played out through the voice broadcast device.
