Problems solved by technology

In addition, the current QR code scanning and analysis technology is highly dependent on the scanning camera. Once the camera equipment is old or damaged, the success rate of scanning and recognition will be greatly reduced.

Embodiment 1

[0040] This embodiment provides a method for quickly parsing a two-dimensional code image, such as figure 1 shown.

[0041] Step 1: Obtain the QR code image and store the QR code image.

[0042] The method of obtaining the two-dimensional code image can be to use the camera to directly capture the two-dimensional code image, and / or receive the two-dimensional code image through the network. According to the different methods of obtaining the two-dimensional code image, the two-dimensional code image can also be divided into no image The original file of the QR code image with noise, that is, the original image; and the non-original image of the QR code with image noise, such as a captured image. If the image data is obtained through the network, the high-definition camera hardware is no longer needed at this time; if the camera is used to take pictures, then compared with the method of using the camera to scan the code to analyze the two-dimensional code image, the solution o...

Embodiment 2

[0059] This embodiment provides a device for quickly analyzing a two-dimensional code image, including:

[0060] The image receiving unit is used to acquire the two-dimensional code image. The image of the two-dimensional code can be captured by the camera, and / or the image of the two-dimensional code can be received directly through the network.

[0061] The data storage unit is used for storing the two-dimensional code image, and the two-dimensional code image can be stored in the storage unit.

[0062] The image judging unit is used to call the two-dimensional code image and judge the type of the two-dimensional code image. The two-dimensional code image can be called through the storage unit to determine whether the two-dimensional code image belongs to the original code image or the non-original code image. The original code image refers to the original QR code image file without image noise, and the non-original code image refers to the QR code shot or scanned image wi...

Abstract

The invention relates to the field of data identification, in particular to two-dimensional code technology. The present invention proposes a method for rapidly analyzing a two-dimensional code image, comprising: step 1: calling the two-dimensional code image; step 2: judging the type of the two-dimensional code image; step 3: selecting the relevant Corresponding image analysis method; step 4: based on the image analysis method, analyze the two-dimensional code image. The invention solves the technical problems of low success rate of high-density two-dimensional code analysis and high dependence of two-dimensional code analysis technology on the camera, improves the recognition success rate and recognition speed, reduces the dependence on hardware, and saves costs.

Description

technical field [0001] The invention relates to the field of data identification, in particular to two-dimensional code technology. Background technique [0002] URL is a uniform resource locator, a concise representation of the location and access methods of resources that can be obtained from the Internet, and is the address of standard resources on the Internet. Every file on the Internet has a unique URL, which contains information indicating where the file is located and what the browser should do with it. In the prior art, since the two-dimensional code generally relies on the URL to make a network request and contains less content, the density of the two-dimensional code is relatively low. In this case, it is relatively easy to analyze and obtain the content of the QR code by scanning the camera, or the success rate of scanning the QR code with the camera is relatively high. But as the density of the QR code increases, the success rate of scanning and parsing will d...
