Abstract

The present application discloses a method, device and storage medium for extracting text information. Specifically, the image to be processed is acquired first, and the first area is extracted in the image to be processed, wherein the first area is where the fixed text in the image to be processed is located. Next, match the first region with the second region in the template image, and filter out the template image to be adapted that meets the matching conditions in the template image, and then calculate the image to be processed and the template image to be adapted Finally, the template image to be adapted corresponding to the adaptation ratio with the largest value is selected as the adaptation template image, and the image to be processed is projected to the adaptation template image, and it is recognized that the image to be processed is projected on the adaptation template image Textual information in at least one structured area. In the embodiment of the present application, a template image is adapted for each image to be processed, and the text information in the image to be processed is analyzed according to the adapted template image, so as to extract the text information in a structured manner.

Description

technical field [0001] The present application relates to the technical field of the Internet, in particular to a method, device and storage medium for extracting text information. Background technique [0002] Optical Character Recognition (OCR) technology can refer to electronic devices (such as scanners or digital cameras) to check characters printed on paper, determine their shapes by detecting dark and light patterns, and then use character recognition methods to translate the shapes into computer text. Because it can detect and recognize text information in pictures, it is widely used in many fields. [0003] OCR technology can assist in entering bill information and assisting in auditing and verification, saving a lot of labor costs. After applying OCR technology, the text position and its corresponding text content in the picture can be obtained. In most cases, especially for the OCR task of bill type images, if there are many types of bills and there is no unifor...
