Problems solved by technology

[0003] At present, there are two-dimensional code scanning devices that include a fill light, but the fill light cannot automatically adjust the on and off status according to the use environment. It needs to be manually set to turn on and off the fill light, which is inconvenient to use and affects the user experience. Spend

Embodiment 1

[0056] Please refer to figure 1 , Embodiment 1 of the present invention is:

[0057] A two-dimensional code scanning supplementary light method, the method is:

[0058] The S1 camera is turned on; the processor records the on-off status of the current fill light;

[0059] The S2 processor collects and stores the two-dimensional code image data through the camera;

[0060] S3 The processor decodes the two-dimensional code image, if the decoding is unsuccessful, the processor changes the on-off state of the supplementary light, and proceeds to step S2 to continue execution.

Embodiment 2

[0061] Please refer to figure 2 , the second embodiment of the present invention is:

[0062] A two-dimensional code scanning supplementary light method, the method is:

[0063] The S1 camera is turned on; the processor records the on-off state of the current supplementary light; the preset decoding cycle records the decoding time of the processor decoding the QR code image since the camera is turned on;

[0064] S11 presets the brightness threshold, and the processor collects and stores the QR code image;

[0065] The processor analyzes the brightness of the stored two-dimensional code image;

[0066] If the brightness is greater than the brightness threshold, the processor controls the fill light to turn off;

[0067] If the brightness is less than or equal to the brightness threshold, the processor controls the fill light to turn on;

[0068] The S2 processor collects and stores the two-dimensional code image data through the camera;

[0069] The S3 processor decodes th...

Abstract

The invention provides a light supplementing method in two-dimensional code scanning and a system thereof. The light supplementing method comprises the steps of S1, starting a camera, recording the current on/off state of a light supplementing lamp; S2, acquiring data of a two-dimensional code image and storing by a processor through the camera; and S3, decoding the two-dimensional code image by the processor, and if decoding fails, changing the on/off state of the light supplementing lamp by the processor, and turning to the step S3 for resuming execution. The system comprises the camera, the light supplementing lamp and the processor. The processor comprises a first recording module, an acquiring module, a storing module, a decoding module and a control module. The camera and the light supplementing lamp are connected with the processor. Through automatically adjusting the on/off state of the light supplementing lamp by the processor, a requirement for determining whether the light supplementing lamp is required according to different environments in which the two-dimensional code is arranged is satisfied. The light supplementing method in two-dimensional code scanning and the system further have advantages of high environment adaptability and flexible and convenient operation.

Description

technical field [0001] The invention relates to the technical field of two-dimensional code identification, in particular to a method and system for supplementing light for two-dimensional code scanning. Background technique [0002] The current two-dimensional code scanning device needs to scan the two-dimensional code that is mainly set on the screen or printed on paper. Since the screen itself emits light, if the two-dimensional code scanning device turns on the fill light when scanning the two-dimensional code set on the screen, it will affect the image data read by the camera, resulting in decoding failure. For the QR code printed on paper, since the paper itself does not emit light and is not easy to emit light, it is necessary to turn on the fill light when scanning the QR code set on the paper to improve the clarity of the image read by the camera. Improve decoding success rate. [0003] At present, there are two-dimensional code scanning devices that include a fil...
