Bill identification method and device, electronic equipment and storage medium

Abstract

The invention provides a bill recognition method and device, electronic equipment and a storage medium, and relates to the field of deep learning and pattern recognition, and the method comprises the steps: obtaining a to-be-recognized target bill; encoding the two-dimensional position information of the plurality of text blocks on the target bill to obtain a plurality of encoding results; performing graph convolution processing on the plurality of coding results to obtain a plurality of convolution results; each convolution result is identified based on a first conditional random field model to obtain a first prediction result of the text block level of the target bill, the first conditional random field model and a second conditional random field model are cooperatively trained, and the second conditional random field model is used for identifying each convolution result to obtain a second prediction result of the text block level of the target bill; and obtaining a second prediction result of the word level of the target bill. The segmentation error introduced by the second conditional random field model is avoided, and the prediction performance of the first conditional random field model is promoted while the performance of the second conditional random field model is improved.

Description

technical field [0001] The present disclosure relates to the fields of deep learning and OCR recognition, and in particular, to a method, device, electronic device and storage medium for bill recognition. Background technique [0002] At present, when entering bill information, it is usually necessary to train a certain number of manual entry personnel to reduce human errors when extracting structured information from bills (receipts). However, the manual entry method is heavy, boring and time-consuming. Effort. SUMMARY OF THE INVENTION [0003] The present disclosure provides a method, apparatus, electronic device and storage medium for bill identification. [0004] According to an aspect of the present disclosure, a bill identification method is provided, which includes: acquiring a target bill to be identified, wherein the target bill includes a plurality of text blocks; Encoding processing to obtain multiple encoding results, wherein the multiple encoding results are...
