Fig. 1 is a schematic flowchart of a click-to-read code identification method based on an electronic screen according to an embodiment of the present invention, where an execution subject of the method is a terminal according to an embodiment of the present invention. Referring to fig. 1, the method for identifying a point-to-read code based on an electronic screen according to this embodiment may include the following steps:
and S101, controlling a screen of the terminal to display a picture paved with a point reading code at preset brightness and gray scale.
In this embodiment, the terminal includes, but is not limited to, an electronic device with a screen display function, such as a mobile phone and a tablet computer. The terminal is internally stored with the picture paved with the point reading code, and the brightness value and the gray value of the picture paved with the point reading code can be rendered while the display brightness and the gray value of a screen of the terminal are controlled.
Because when the picture contrast is lower, can lead to the point reading pen can't discern the point reading code in the picture, and when the picture contrast is higher, can produce some noise jamming to the point reading code that the point reading pen obtained, consequently, adopt control terminal's screen to show the picture of laying the point reading code with preset luminance and grey scale in this embodiment, can make the picture show with certain contrast like this, guarantee the precision and the sensitivity of point reading code discernment.

Step S203, acquiring the click-to-read codes in the multiple screen shot pictures, and splicing the click-to-read codes in the multiple screen shot pictures according to the cache sequence of the multiple screen shot pictures to generate a multi-picture group code.
In this embodiment, after a plurality of screen shot pictures cached in a certain caching period are obtained, the click-to-read codes in the plurality of screen shot pictures can be respectively extracted, and then the click-to-read codes in the plurality of screen shot pictures are spliced according to the caching order of the click-to-read codes in the plurality of screen shot pictures, wherein the plurality of screen shot pictures are cached according to the shooting time order, so that the click-to-read codes in the plurality of screen shot pictures are spliced according to the caching order, that is, the click-to-read codes in the plurality of screen pictures are spliced according to the shooting time order of the plurality of screen pictures, and each screen picture is marked with a shooting time point.
In this embodiment, the multi-image group code is a code segment of a click-to-read code that is spliced by click-to-read codes in the multiple screen shot pictures.
