Abstract

A miniature two-dimensional code reading system comprises a camera device and an image signal receiving device; the camera device is used for shooting a two-dimensional code on a workpiece and generating an image signal of the two-dimensional code; and the image signal receiving device is in signal connection with the camera device; and after the image signal is received, the position of the two-dimensional code is identified through an intelligent image identification module and the two-dimensional code is read. The invention also discloses a miniature two-dimensional code reading method. According to the miniature two-dimensional code reading system and method provided by the invention, the miniature two-dimensional code with an extremely small size can be conveniently identified and read, so that the miniature two-dimensional code marked on the miniature component is more practical.

Description

technical field [0001] The present invention relates to a two-dimensional code reading system and method, in particular to a miniature two-dimensional code reading system and method. Background technique [0002] In the life of modern people, when purchasing goods and managing goods, barcodes are often used to help record items and calculate quantities. With the advancement of science and technology, barcodes are no longer just black and white long strips, but due to the increase in the amount of information, two-dimensional codes have been developed, and due to differences in application fields, the above two-dimensional codes can be further divided into data matrix (data matrix), QR code, PDF417 code, etc. [0003] In addition, because two-dimensional codes can record many commodities and cargo information, in recent years, the outer packaging of many commodities has used two-dimensional codes to mark product information, and even some products have been found using two-d...
