Abstract

The invention discloses an image inclination correction method and device and a storage medium. The method comprises: obtaining a to-be-corrected image of a graphic area containing a target object, wherein the target object is in a rectangular shape; performing image positioning on the to-be-corrected image by using an image positioning model of deep learning, and generating a mask image for segmenting a graphic area from the to-be-corrected image; determining first position information of the graphic area in the to-be-corrected image according to the mask image; and according to the first position information, carrying out inclination correction processing on a graphic area in the to-be-corrected image.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to an image tilt correction method, device and storage medium. Background technique [0002] The development of the mobile Internet has greatly shortened the distance between people and between people and information. For OCR recognition, the key is to accurately locate the text area to be recognized. However, when the user uploads an image containing the target object (for example: ID card, bank card, driving license, social security card, bill, invoice, etc.) Tilt and perspective effects. This will have a great impact on text positioning and OCR recognition accuracy. Therefore, before performing OCR recognition, it is necessary to perform tilt correction processing on the graphics area containing the target object. [0003] The currently commonly used tilt correction method is based on the traditional image processing method. First, the image containing the ...
