Abstract

This specification provides a method, device, device and system for detecting the fill light spot of a code scanning device. After the code scanning device is used to collect a detection image of a specified color palette, the detection image is image-segmented, and the segmented window image is calculated. The average brightness of the detected image and the window image uniformity of the window image are calculated based on the calculated average brightness. Further based on the calculated average brightness and uniformity to detect whether the light spot of the supplementary light of the code scanning device is qualified, the automatic detection of the supplementary light spot of the code scanning device is realized, the detection efficiency of the supplementary light spot is improved, and the program is programmed. The automatic detection standards are consistent, and the detection results are more accurate.

Description

technical field [0001] This specification belongs to the field of computer technology, and in particular, relates to a method, device, device and system for detecting a fill light spot of a code scanning device. Background technique [0002] With the popularization of barcode technology and mobile payment, the recognition of graphic codes such as one-dimensional codes and two-dimensional codes has been gradually applied to various industries in the society, and code scanning equipment has also been widely used. Some code scanning devices are often equipped with supplementary light devices. The supplementary light can be used to compensate for insufficient ambient brightness, enhance the image capture effect of barcodes, and facilitate rapid barcode recognition. However, the installation position of the fill light and the brightness specification will affect the quality of the generated light spot, thereby affecting the image effect obtained by the code scanning device, and u...
