Abstract

The invention relates to the technical field of two-dimensional code scanning, and discloses a code scanning method. The method comprises the following steps: acquiring a two-dimensional code image containing a two-dimensional code, and graying the two-dimensional code image by using a weighted average method to obtain a two-dimensional code grayscale image; performing noise reduction processing on the two-dimensional code grayscale image by using a bilateral filtering algorithm to obtain a denoised two-dimensional code grayscale image; performing binarization processing on the denoised two-dimensional code grayscale image by using an improved binarization algorithm to obtain a binarized image of the two-dimensional code; positioning the two-dimensional code by using a dynamic two-dimensional code positioning algorithm to obtain an area where the two-dimensional code is located; according to the area where the two-dimensional code is located, decoding the two-dimensional code by usinga two-dimensional code decoding method to obtain a code scanning result of the two-dimensional code. The invention further provides a code scanning device and a mobile terminal. According to the invention, the scanning of the two-dimensional code is realized.

Description

technical field [0001] The invention relates to the technical field of two-dimensional code scanning, in particular to a code scanning method, a code scanning device and a mobile terminal. Background technique [0002] With the vigorous development of computer technology and the gradual popularization of smart devices, two-dimensional code recognition technology has emerged as the times require. As a medium for information transmission, two-dimensional codes have been used in all aspects of production and life such as shopping malls, supermarkets, industrial production lines, and postal express delivery. The scanning and recognition of two-dimensional codes has become a hot topic in the current research field. [0003] For the recognition of two-dimensional codes, an image recognition device equipped with a camera is often used, which is matched with a suitable recognition software to recognize it. In daily life, this kind of equipment has a simple structure and low price, ...
