Abstract: A method for generating word code, a method and device for recognizing codes are provided, and they are falling within the field of machine visual recognition. The method for recognizing word code includes: acquiring an image containing word codes, and recognizing target words therein; splitting the target words according to the same rule, and then recognizing all visual anomaly split sequences, and performing determination on the word codes, if the word codes are generated on the basis of an encoding mechanism designed by a system, directly reading same and performing invoking; otherwise, invoking a pre-inputted target file of the word codes according to target word meaning sequence numbers and visual anomaly sequences numbers corresponding to the word codes.
