The invention relates to the field of big data, and discloses a bill classification method, which comprises the steps of obtaining field information of to-be-classified bills; determining the same specified field in the to-be-classified bills and the specified bill template according to the character content of the field; constructing a transformation matrix between the to-be-classified bills andthe specified bill template according to the first coordinate information of all the specified fields in the to-be-classified bills and the second coordinate information of all the specified fields inthe specified bill template, and constructing transformation matrixes corresponding to all the bill templates; respectively carrying out transmission transformation on the coordinate information of the the to-be-classified bills by the transformation matrixes respectively corresponding to all the bill templates to obtain transformed coordinate information in a one-to-one correspondence manner; calculating matching scores of the the to-be-classified bills and the bill templates according to the transformed coordinate information and the coordinate information of the fields in the specified bill templates; and taking the bill templates corresponding to the minimum matching score as a classification template corresponding to the the to-be-classified bills.
Description
technical field [0001] This application relates to the field of big data, in particular to a method, device and computer equipment for classifying bills. Background technique [0002] At present, the processing of bills by most small and medium-sized enterprises mainly relies on manual entry of bill information, converting the content of paper bills into storable structured information. Manual entry is not only inefficient and takes a long time, but also in high-intensity Under the pressure of repeated work, it is inevitable that mental slack will lead to work mistakes, which cannot meet the pursuit of efficiency and intelligence in bill information management. Although the optical character recognition (OCR) technology can be used to automatically classify the bills into the template library with the help of the automatic classification model. However, the existing automatic classification model requires users to upload at least 15-20 pictures of each type of bills for mod...
