Abstract

The invention relates to an artificial intelligence technology, is specifically applied to image processing, and discloses an invoice information extraction method and device, computer equipment and astorage medium. The method comprises the steps of acquiring a bill image; performing layer separation on the bill image by using a pre-trained separation model to obtain a machine-printed image and aprinted image, the separation model being obtained by training based on an adversarial generative network model; identifying the machine-printed image and the printed image by adopting correspondingpre-trained identification models respectively, converting the machine-printed image and the printed image into a machine-printed text and a printed text, and obtaining the identification models by training based on a convolutional recurrent neural network model; and correspondingly matching the machine-printed text with the printed text to form a bill text. The invention also relates to a blockchain technology. The bill image and the bill text data are stored in the blockchain. According to the method, the text recognition accuracy is improved, and the bill information is typeset again to obtain the bill text.

Description

technical field [0001] The present application relates to the technical field of artificial intelligence, in particular to a method, device, computer equipment and storage medium for extracting invoice information. Background technique [0002] OCR (Optical Character Recognition, Optical Character Recognition) is an important research direction in the field of pattern recognition. In recent years, with the rapid update and iteration of mobile devices and the rapid development of the mobile Internet, OCR has a wider range of application scenarios, from the character recognition of scanned documents in the past to the recognition of pictures and texts in natural scenes. Such as identifying text in ID cards, bank cards, house numbers, bills and various network pictures. In the existing technology, OCR technology is used to automatically identify and extract the field information on the bill and complete the structured output. However, when the fields on the bill are overlapped...
