Embodiment 1

[0093] The embodiment of the present application provides a two-dimensional code recognition method, such as figure 1 As shown, it is a schematic flow chart of the two-dimensional code recognition method provided in the embodiment of the present application, including the following steps:

[0094] S101. Acquire an image to be processed.

[0095] Wherein, the image to be processed may be an image containing a two-dimensional code.

[0096] S102. Identify a positioning frame in the image to be processed.

[0097] S103. If the number of identified positioning frames is less than the preset number, determine the positions of missing positioning frames in the image to be processed based on the positions of the identified positioning frames.

[0098] S104. Based on the identified position of the positioning frame and the position of the missing positioning frame, locate the two-dimensional code in the image to be processed, and decode the two-dimensional code.

[0099] In the spe...

Embodiment 2

[0148] In the embodiment of the present application, several possible results that may occur after identifying the positioning frame in the image to be processed will be combined with the first embodiment to give a general description, see Figure 10 As shown, it is a schematic flow chart of a two-dimensional code recognition method provided in the embodiment of the present application, including the following steps:

Abstract

The invention relates to the technical field of image processing, in particular to a two-dimensional code recognition method and a two-dimensional code recognition device. The two-dimensional code recognition method comprises the steps of: acquiring a to-be-processed image, and executing a recognition process, wherein the recognition process comprises the step of recognizing positioning frames inthe to-be-processed image; if the number of the identified positioning frames is smaller than a preset number, determining positions of missing positioning frames in the to-be-processed image based onpositions of the identified positioning frames; and based on the identified positions of the positioning frames and the positions of the missing positioning frames, positioning a two-dimensional codein the to-be-processed image, and decoding the two-dimensional code. By means of the two-dimensional code recognition method, the accuracy rate and efficiency in the two-dimensional code recognitionprocess can be improved.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to a two-dimensional code recognition method and device. Background technique [0002] QR code, also known as Quick Response Code (Quick Response, QR Code), is a popular coding method on mobile devices in recent years. It can store more information and represent more data types. [0003] At present, QR codes can be applied in many scenarios, such as scanning codes for payment, or unlocking shared bicycles by scanning codes. Or there are reasons such as defects in the two-dimensional code, so that the complete two-dimensional code cannot be scanned, and then the two-dimensional code cannot be accurately decoded to obtain the information recorded in the two-dimensional code. Contents of the invention [0004] In view of this, an embodiment of the present application provides a two-dimensional code recognition method, so as to improve the accuracy and recognition ...
