Disclosed in the present invention are a four dimensional code and four dimensional code-based image recognition system and method, retrieval system and method. All concepts of the present invention are mainly based on the four dimensional code, the four dimensional code comprising: a recognition image and a set of recognition data corresponding to the recognition image. The recognition image comprises: a true color image, a two dimensional code, a color overlaid on the two dimensional code, and an ID number, and the true color image, the two dimensional code, the color overlaid on the two dimensional code and the ID number have the same index or corresponding indexes. The data corresponding to the four dimensional code is stored on a server, and upon scanning the four dimensional code or recognition image for recognition or retrieval, and the corresponding data can be retrieved via image recognition processing and returned to the mobile terminal. The present invention has high identification precision and a wide application scope and can be used for various commercial purposes. |
