Problems solved by technology

Most of the existing methods are to manually identify the invoices. This method is firstly cumbersome and consumes a lot of labor; secondly, the efficiency is extremely low.
Now some use OCR recognition to obtain invoice information, and even use deep learning to carry out model training, but due to the multi-dimensionality of the invoice information itself, its recognition effect and recognition efficiency are not very good. On the other hand, due to lack of care Due to the multi-dimensionality of the invoice information, it does not have a good correction effect on the OCR recognition results

Abstract

The invention discloses an invoice identification method and device. The method comprises the following steps: acquiring an invoice; cutting the invoice according to the content to obtain partitions;segmenting the content in the partition according to the entries to obtain subsets; identifying the subsets to obtain subset contents of the corresponding subsets; and restoring the subset contents ofall the subsets to the corresponding positions of the invoices to obtain invoice contents. According to the method, the invoice is subjected to secondary segmentation by utilizing the characteristicsof the invoice, the subsets are obtained after the partitions are obtained, and due to sequential segmentation of the subsets and the partitions, relative directional identification can be carried out according to the specific content of the subsets, so that the identification speed and accuracy can be improved.

Description

technical field [0001] The application relates to an invoice identification method and device. Background technique [0002] As an important tax and accounting carrier for economic activities, invoices are widely used, especially in reimbursement, and are generally used as reimbursement vouchers. Most of the existing methods are to manually identify the invoices. This method is firstly cumbersome and consumes a lot of labor; secondly, the efficiency is extremely low. Now some use OCR recognition to obtain invoice information, and even use deep learning to carry out model training, but due to the multi-dimensionality of the invoice information itself, its recognition effect and recognition efficiency are not very good. On the other hand, due to lack of care Due to the multi-dimensionality of the invoice information, it does not have a good correction effect on the OCR recognition results. Contents of the invention [0003] In order to solve the above problems, the present...
