Abstract

The invention relates to the technical field of image processing, in particular to a method and a device for extracting cash receipt information. The method for extracting the specified information of the cash register note includes the following steps: performing layout analysis on the first cash register note; selecting a first numerical value field from the first cash register note; calculating a key field corresponding to the first numerical value field ; Generating a template; Obtaining a target key field from the cash register receipt to be identified according to the template, and calculating a target numerical field; performing text recognition on the target numerical field. The invention can establish a specific template according to the type of data to be obtained by the user, simplifies the input of parameters, reduces the amount of calculation, shortens the time for data extraction, and satisfies the requirement of real-time data extraction; at the same time, it improves the recognition efficiency and accuracy.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method and a device for extracting cash receipt information. Background technique [0002] With the continuous development of science and technology and the continuous improvement of people's living standards, various consumer places such as shopping malls, supermarkets, and restaurants have begun to use the cash register system to settle the goods purchased by consumers, realizing automated business management.
