Embodiment 1

[0026] figure 2 It is a flow chart of the encoding recognition method provided in Embodiment 1 of the present invention, the method is applied to a mobile terminal, and the method may specifically include the following steps:

[0027] Step 110, performing multiple scans on the same coded image to obtain multiple initial images.

[0028] It should be noted that the aforementioned mobile terminals include terminals such as mobile phones and tablet computers. The mobile terminal can scan the same coded image through the camera, so as to collect multiple initial images that identify the same code.

[0029] The above coded image may be an image containing codes such as one-dimensional codes, two-dimensional codes, and three-dimensional codes. If there is a light spot on the coded image, there will be a corresponding missing pixel area in the collected initial image. In this pixel missing area, part of the code is blocked by the light spot, and the mobile terminal cannot scan the...

Embodiment 2

[0041] image 3 It is one of the flow charts of the code recognition method provided in Embodiment 2 of the present invention, the method is applied to a mobile terminal, and the method may specifically include the following steps:

[0042] Step 210, perform multiple scans on the same coded image to obtain multiple initial images.

[0043] Optionally, the step 210 may include the following steps:

[0044] Step 211, when receiving the code recognition instruction submitted by the user for the coded image, call the camera of the mobile terminal to scan the coded image to obtain a single frame image.

[0045]In a specific implementation, when the user needs to identify the code, the user can submit a code recognition instruction on the mobile terminal to trigger the recognition process for the code. For example, a user opens the function of scanning a QR code on WeChat.

[0046] When the mobile terminal receives the code recognition instruction, it can call the camera to scan ...

Embodiment 3

[0090] Image 6 It is a structural block diagram of a mobile terminal provided in Embodiment 3 of the present invention, and the mobile terminal 300 may specifically include the following modules:

[0091] The scanning module 310 is configured to perform multiple scans on the same coded image to obtain multiple initial images.

[0092] A synthesis module 320, configured to synthesize the multiple initial images to obtain a target image.

[0093] The recognition module 330 is configured to recognize the target image and obtain a recognition result.

[0094] Optionally, the synthesis module 320 includes:

[0095] The pixel filling image extraction sub-module 321 is used to extract a plurality of pixel filling areas from the multiple initial images for the pixel missing areas in at least one initial image when it is recognized that there are pixel missing areas in the multiple initial images image;

[0096] The image combining submodule 322 is used to combine the at least one...

Abstract

The embodiment of the invention discloses a code recognition method and a mobile terminal. The method comprises the steps that the same coded image is scanned multiple times to obtain multiple initialimages; the initial images are synthesized to obtain a target image; and the target image is recognized to obtain a recognition result. According to the embodiment, the same coded image is scanned multiple times to obtain the initial images, the initial images are synthesized to obtain the target image containing a complete code, and therefore the code recognition rate is increased.

Description

technical field [0001] The embodiment of the present invention relates to the field of communication, and in particular to a code recognition method and a mobile terminal. Background technique [0002] At present, more and more users obtain various network services by scanning coded images such as one-dimensional codes and two-dimensional codes. For example, scan the one-dimensional code on the product to query product information, scan the two-dimensional code on the payment counter to pay the merchant, scan the two-dimensional code to use the shared bicycle, etc. [0003] Usually, in order to make the coded image clear and durable, the coded image is usually printed on reflective paper, or the surface of the coded image is covered with a material with strong reflection such as transparent plastic or glass. At night or in a dark environment, the mobile phone may not be able to recognize a clear coded image, so the user will turn on the flashlight of the mobile phone and us...
