Embodiment 1

[0049] see image 3 , is a schematic flowchart of a method for displaying an image based on a curved screen provided by an embodiment of the present invention. image 3 The shown method is applied to a display device with a curved screen, the method comprising:

[0050] S301: Generate a new image according to the degree of curvature of the curved screen and the image to be corrected; wherein the image to be corrected includes a two-dimensional code to be corrected or a barcode to be corrected.

[0051]S302: On the curved screen, display a new image; wherein, the image obtained after the new image displayed on the curved screen is mapped onto a plane is equal in size to the image to be corrected.

[0052] For example, for a display device with a curved screen, steps S301-302 can be performed before displaying the image, so that the new image will be displayed directly on the curved screen, and the image to be corrected will not be displayed; or the image to be corrected can be...

Embodiment 2

[0069] see Image 6 , is a schematic flowchart of a method for recognizing an image based on a curved screen provided by an embodiment of the present invention. For the explanation of relevant content in this embodiment, reference may be made to the above. Image 6 The methods shown include:

[0070] S601: Scan the image to be corrected displayed on the curved screen of the display device to obtain a first scanned image; wherein the image to be corrected includes a two-dimensional code to be corrected or a barcode to be corrected.

[0071] The executor of this embodiment may be a scanning device for scanning images displayed on a curved screen, specifically, a smart phone, a tablet computer, and the like.

[0072] S602: Identify the first scanned image.

[0073] For example, an application for recognizing images is installed in the scanning device, and the first scanned image is recognized based on the application. If the recognition is successful, the information represent...

Embodiment 3

[0079] see Figure 7 , is a schematic flowchart of a method for displaying and recognizing a two-dimensional code based on a curved screen according to an embodiment of the present invention. Figure 7 The methods shown include:

[0080] S701: The display device displays the original two-dimensional code on the curved screen. Among them, the "original QR code" is the QR code to be corrected above.

[0081] S702: The scanning device scans the original two-dimensional code displayed on the curved screen of the display device to obtain a first scanned two-dimensional code.

[0082] S703: The scanning device recognizes the first scanned QR code, and determines whether the recognition is successful.

[0083] If yes, end; if not, execute S704.

[0084] S704: The scanning device sends a correction request message to the display device, wherein the correction request message is used to request correction of the original two-dimensional code displayed on the curved screen.

Abstract

The invention discloses a method and an apparatus of displaying and recognizing images on the basis of a curved screen. The method and apparatus relate to the technical field of image processing with the object of solving problem in the prior art that when a user scans an image displayed on a curved screen, the image is recognized at a low rate. The method comprises the production of a new image based on the curving degree of the curved screen and a to-be-corrected image. The to-be-corrected image comprises a to-be-corrected two-dimensional code or a to-be-corrected bar code. On the curved screen, the new image is displayed and when the new image is mapped on a plane, the size of the new image is identical to that of the to-be-corrected image.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method and device for displaying and recognizing images based on a curved screen. Background technique [0002] A two-dimensional code is a black and white graphic that uses a specific geometric figure to be distributed on a plane according to a certain rule to record data symbol information, and its application range is very wide. Curved TVs, that is, TVs with curved screens, are widely used due to their advantages such as high contrast and wide viewing angles. When the original QR code is directly displayed on the curved TV, the QR code scanned by smart phones and other devices will be deformed compared with the original QR code, resulting in a low recognition success rate. Contents of the invention [0003] Embodiments of the present invention provide a method and device for recognizing images based on curved screen display to solve the problem of low recognition...
