The invention relates to the field of image recognition and the field of natural language processing, and discloses a bill recognition method and device. The method comprises the steps of obtaining abill picture, and obtaining a machine recognition result of a key field in the bill picture and feature data associated with the machine recognition result; obtaining confidence coefficients of the machine recognition results of the key fields based on the feature data associated with the machine recognition results and the binary classification models corresponding to the key fields, enabling thebinary classification models to be in one-to-one correspondence with the key fields, and finally judging the confidence coefficients of the machine recognition results of the key fields; and in response to determining that the confidence of the machine identification result of the key field meets a preset condition, determining the machine identification result of the key field as an identification result of the key field
