Abstract

The invention provides a character recognition method, device and equipment, and a storage medium. The method comprises the steps of determining position information of a target corner point of a cardregion in an image in the image; converting the card area from a current view angle to a target view angle according to the position information of a target corner point, wherein the target view angle is a view angle directly facing a card when an image is acquired; determining at least one target text area in the converted card area; and inputting each target character region into a trained first neural network, so that the first neural network identifies and outputs characters in the target character region. And the problem of relatively low character recognition accuracy caused by character distortion is avoided.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a character recognition method, device and equipment, and a storage medium. Background technique [0002] In some occasions, it is necessary to recognize the text on the cards in the collected images, such as ID cards, business cards, passports, etc., so as to further perform information entry and other processing. [0003] In related technologies, regardless of the angle of view at which the card image is collected, after the card image is collected, the text is directly located in the collected original image, and the located text is recognized. [0004] In the above method, since the text is directly located and recognized on the original image collected, the card area in the original image may be distorted. If the distortion correction is not performed on the card area, the text in the card area will also be distorted. , leading to the problem of low text re...
