Abstract

The invention relates to artificial intelligence, and provides an electronic invoice information extraction method and device, equipment based on artificial intelligence and a medium, and the method comprises the steps: firstly obtaining a frame set of a to-be-recognized electronic invoice picture, a recognition text in each frame, and a corresponding target electronic invoice template; carrying out coordinate normalization adjustment on the to-be-recognized electronic invoice picture to obtain an adjusted electronic invoice picture, and then obtaining a Sudoku matching similarity and a matching label corresponding to each pixel point based on the adjusted electronic invoice picture; and finally, positioning a target frame of the to-be-matched target text in the frame set, determining that the label combination of the pixel point labels in the adjusted frame is the same as the to-be-matched target text, taking the target frame as a target area, and obtaining a target value of the target area. The template-based information extraction is realized, the algorithm is light and simple, the operation speed is high, and the accuracy is high.

Description

technical field [0001] The present invention relates to the field of image recognition of artificial intelligence, in particular to an artificial intelligence-based electronic invoice information extraction method, device, computer equipment and storage medium. Background technique [0002] At present, document intelligence mainly refers to the understanding, classification, extraction and information induction of text and typesetting information contained in scanned documents through artificial intelligence technology. The structured data obtained according to document intelligence technology can also be used for higher-level intelligent applications, such as: information mining, intelligent decision-making, etc. The research on document intelligence has been gradually rising in recent years. [0003] At this stage, there are some researches on structured information extraction, which can solve some specific tasks, such as: (1) An algorithm for information extraction of bi...
