All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
When a plurality of graphic codes are included in the graphic code image, if the plurality of graphic codes in the graphic code image need to be identified, the identified graphic code image needs to be displayed first, and then a scanning result of the graphic code marked by the icon is added at the corresponding position of the graphic code image according to the identified graphic code coordinate information. There are two presentations, one presenting the identified image and the other presenting the identified coordinate points in the image. Because the sizes of the image and the display control are inconsistent, the display control cannot be filled with the image directly, or the coordinates cannot be aligned after the display control is attempted to be filled, so that the display effect is poor, and the image and the display control need to be integrally adapted when the graphic code is displayed.
In the prior art, when the graphic code image and the display control are subjected to adaptation adjustment, the graphic code image is identified through a graphic code identification program to obtain graphic code position information, and then the graphic code position information and the graphic code image are subjected to adaptation adjustment, so that the graphic code image is aligned in the center of the display control, and the coordinate position of the graphic code is in the center of the graphic code.
Fig. 1 is a schematic diagram of the prior art, which is transversely paved when a graphic code image is adaptively displayed, and as shown in fig. 1, graphic code identification is firstly performed on the graphic code image 1 to obtain graphic code position information 2; then, carrying out adaptation adjustment on the graphic code image 1 and the graphic code position information 2 to enable the adjusted graphic code image 3 to be transversely paved with display controls, and carrying out adaptation adjustment on the graphic code position information 2 relative to the adjusted graphic code image 3 to enable the coordinate position of the graphic code adjusted in the adjusted graphic code image 3 to be in the center of the graphic code; and displaying the adjusted graphic code image and the adjusted graphic code position information in a display control to obtain a display image 4.
Fig. 2 is a schematic diagram of the prior art, which is longitudinally paved when a graphic code image is adaptively displayed, and as shown in fig. 2, graphic code identification is firstly performed on the graphic code image 5 to obtain graphic code position information 6; then, carrying out adaptation adjustment on the graphic code image 5 and the graphic code position information 6 to enable the adjusted graphic code image 7 to be longitudinally paved with display controls, and carrying out adaptation adjustment on the graphic code position information 6 relative to the adjusted graphic code image 7 to enable the coordinate position of the graphic code adjusted in the adjusted graphic code image 7 to be in the center of the graphic code; and displaying the adjusted graphic code image and the adjusted graphic code position information in a display control to obtain a display image 8.
