Intelligent bill information extraction processing method

Abstract

The embodiment of the invention discloses an intelligent bill information extraction processing method, which comprises the following steps: shooting a bill to generate a bill electronic picture; determining an identification range, and identifying the maximum range occupied by the bill electronic picture; defining an identification sequence, defining the identification sequence according to a bill typesetting rule, and sorting identification results; identifying bill information, scanning effective electronic areas according to an identification sequence, judging a current bill type, extracting bill type data, and meanwhile, obtaining keyword classification information contained in the current bill type; defining an information extraction rule, and stipulating the information extraction rule according to the bill type; and implementing an information extraction operation, identifying bill information, and searching key information in the bill picture according to the information extraction rule. According to the scheme, the bill structured information is extracted by dynamically defining the spatial relationship, and line feed, truncation and vertical texts in the bill can be wellprocessed.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of image information identification, and in particular to a method for extracting and processing intelligent bill information. Background technique [0002] A bill is a written certificate reflecting the relationship between creditor's rights and debts. Bills occur in market exchange and circulation, reflecting the creditor-debt relationship between the parties. Specifically, in the exchange of property (commodities, currency, and other property rights), both parties have certain rights and obligations in terms of property, that is, a creditor-debt relationship has occurred, which requires confirmation and expression in written form. To ensure that both parties realize their respective rights and obligations. It is on this basis that bills are produced. There is no bill if there is no real creditor-debt relationship. Therefore, written evidence reflecting the relationship betwee...

Problems solved by technology

[0005] To this end, the embodiment of the present invention provides a method for extracting and processing intelligent bill information, which adopts the scanning method from top to bottom and from left to right to identify the bill picture, and uses the method of dynamically defining the spatial relationship to extract the structural information of the bill. Line breaks, truncation, and vertical text in the text can be handled very well, solving the problem that existing technologies are difficult to correctly extract complex bill information
