Barcode scanner with dynamic multi-angle lighting system and barcode scanning method thereof

Abstract

The invention provides a bar-code scanner with a dynamic multi-angle illuminating system. The bar-code scanner with the dynamic multi-angle illuminating system comprises an outer shell, a glass window, an illuminating module, a camera shooting module, a light sensing device and a main board with a central processor, wherein the illuminating module comprises a plurality of light-emitting diodes (LEDs) of different illuminating angles, the plurality of LEDs are arranged in front of the camera shooting module, the plurality of LEDs of the same illuminating angles form an LED array, and the plurality of LEDs of different illuminating angels comprise far-field illuminating LEDs and near-field illuminating LEDs. The invention further provides a bar-code scanning method of the bar-code scanner. Compared with the prior art, the bar-code scanner and the bar-code scanning method of the bar-code scanner can be suitable for illuminating requirements of bar-code scanning of multiple scenes, improve the bar-code identifying rate, and enlarge the application range of a bar-code scanning device.

Description

technical field [0001] The invention relates to the technical field of barcode scanning equipment, in particular to a barcode scanner with a dynamic multi-angle lighting system and a barcode scanning method thereof. Background technique [0002] Barcode scanners, also known as barcode readers, barcode scanners, barcode scanners, barcode scanners and barcode readers. It is a reading device used to read the information contained in the barcode. Using the principle of optics, the content of the barcode is decoded and then transmitted to a computer or other equipment through a data line or wirelessly. Barcode scanners are widely used in commercial POS cash register systems, express delivery, warehousing, logistics, books, medicine and other fields. [0003] In many industrial applications, barcodes are not only printed on paper labels. In some automotive and electronic industries, more and more companies make barcodes directly on parts by laser engraving, spraying, etching or e...

AI Technical Summary

Problems solved by technology

Due to the simple structure of the lighting module of the barcode scanner in the prior art, the lighting mode of the lighting module is single, the lighting angle and the lighting distance are fixed values, it is difficult to meet the lighting requirements of various application scenarios

Therefore, barcode scanners in the prior art cannot perform lighting mode conversion, but can only use a single-mode lighting system to scan barcodes, especially for barcodes printed on paper labels, and for other material surfaces. Barcodes directly engraved, sprayed, etched or cast on the surface cannot be recognized smoothly in most cases, and the recognition rate is very low
