Abstract

The invention relates to image processing, and discloses a bank card picture correction method and device, equipment and a storage medium, and the method comprises the steps: obtaining a bank card picture and a local pre-stored bank card picture template; performing feature point matching on the bank card picture according to the bank card picture template, and obtaining a transformation matrix between the bank card picture template and the bank card picture according to a matching result; affine transformation is carried out on the bank card picture according to the transformation matrix; obtaining a corrected target bank card picture. According to the embodiment of the invention, feature point matching is carried out on the bank card picture according to the preset bank card picture template; and then a transformation matrix is constructed according to the matching result, and affine transformation is carried out on the bank card picture according to the transformation matrix to obtain a corrected target bank card picture, so that various shot non-compliant bank card pictures can be corrected, and the smooth extraction of the bank card information in the subsequent process is ensured.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a bank card image correction method, device, equipment and storage medium. Background technique [0002] In the Internet field, online transactions are often accompanied by the entry of bank card information. For example, when users purchase goods through client applications, they need to enter the corresponding bank card account to complete the payment. However, due to the large number of bank card numbers involved, users It is often easy to make mistakes when entering manually, and the experience is relatively poor. Therefore, most of the current clients have the function of recording and recording bank card content information, but in fact, when users take bank card pictures through the camera, due to bank card placement tilt or equipment hardware, it cannot guarantee that every image captured The pictures are all in normal shape. Most of the collected pictures have ...
