Abstract
The invention discloses a four-dimensional code, an image identification system and an image identification method based on the four-dimensional code, a retrieval system and a retrieval method. All the conceives of the invention are mainly based on the four-dimensional code which includes an identification image and a group of recognition data corresponding to the identification image, wherein the identification image includes a true color image, a two-dimensional code, a color overlaid on the two-dimensional code, and an ID No., and the true color image, the two-dimensional code, the color overlaid on the two-dimensional code and the ID No. have same or corresponding indexes. Data corresponding to the four-dimensional code is stored through a server, and the four-dimensional code or the identification image is scanned during identification or retrieval, so that corresponding data can be retrieved through image identification processing, and returned to a mobile terminal. The invention has high identification precision and broad application range, and can be applied to various commercial purposes.
