Picture processing method and device and computer readable storage medium

Abstract

The invention relates to a picture processing method and device and a computer readable storage medium. The method comprises the following steps that: according to the edge line of an object to be identified in an original picture, determining the practical coordinate of each vertex of the object to be identified under a first coordinate system; according to the edge line of the object to be identified, determining the standard size of the object to be identified, and according to the standard size, obtaining the standard coordinate of each vertex of the object to be identified under the firstcoordinate system; and according to the practical coordinate and the standard coordinate of each vertex, solving a distortion correction matrix, and utilizing the distortion correction matrix to carry out correction processing on the original picture to obtain a corrected picture. By use of the scheme provided by the invention, the automatic correction of the object to be identified in the original picture can be realized.

Description

technical field [0001] The present disclosure relates to the field of image processing, and in particular to an image processing method and device, and a computer-readable storage medium. Background technique [0002] With the rise of the mobile Internet, it plays more and more functions in people's work and life, such as Internet identification, Internet finance, Internet payment, etc. In the process links in the mobile Internet field, users may be required to upload some material pictures. At present, mobile terminals are becoming an indispensable part of people's social life. If the pictures captured by mobile terminals are combined with the mobile Internet, it will greatly improve work efficiency and save costs. [0003] Taking a practical application as an example, in the field of Internet payment, users need to be authenticated. For example, for real-name authentication, users need to upload ID card pictures. For another example, the current optical character recogni...

Problems solved by technology

However, in practical applications, the above-mentioned application scenarios have relatively strict requirements on the quality of the image itself. Taking OCR products as an example, the common application scenarios require the use of professional matching camera equipment and scanners bound to OCR software to provide Identification services, which are both costly and inconvenient

[0004] The reason for the above situation is due to the influence of lighting, complex background, human factors, etc. Usually, the pictures taken by the mobile terminal may have various quality problems, for example, there may be tilt distortion, which makes the pictures taken by the mobile terminal not very good. applied in the field of mobile Internet
