Embodiment Construction

[0113] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

[0114] The embodiments of the present disclosure can be applied to the scene where verification information is uploaded after taking photos of card documents such as certificates. Since the card may be illuminated by strong light, there may be reflective areas in the card image, or there may be reflective areas in the card image due to overexposure, which may cause the card The information in th...

Abstract

The present invention relates to a card image reflective detection method and device, and belongs to the image processing technology field. The method comprises the steps of obtaining a to-be-detected card image; carrying out the reflection removing processing on the to-be-detected card image; carrying out the character detection on the card image after the reflection removing processing to obtain a character detection result, and determining whether the to-be-detected card image reflects light according to the character detection result. The device comprises an image obtaining module, a reflection removing module, a character detection module and a determination module. According to the embodiment of the present invention, whether the card image reflects light can be detected effectively, and the method and the device of the present invention are especially suitable for a card image information automatic identification technology.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, in particular to a card image reflective detection method and device. Background technique [0002] In people's daily life, it is often necessary to obtain relevant information from documents. With the rapid development of technologies such as computers and image processing, the use of computers to automatically identify and enter relevant information has become more and more popular. [0003] In related technologies, card images such as certificates are usually captured by means of photographing or scanning, and then the collected card images are processed and analyzed to automatically identify and extract relevant information in the card images. However, if there is a reflective area in the acquired card image, the information in the reflective area may not be recognized or the recognition result may be wrong, which may eventually lead to the failure of relevant information e...
