Barcode automatic identification collecting-imaging system and method

Abstract

The invention discloses a barcode automatic identification collecting-imaging system. The system comprises two parts, namely a collector end and a PDA end; the collector end consists of an optical system and an imaging system; the PDA end consists of an image pre-processing system and a decoding system; optical information collected by the optical system is output after passing through the imaging system, the image pre-processing system and the decoding system in sequence; the optical system includes three parts, namely an LED light supplementing lamp, a lens and a light guiding lens; and a CMOS imaging technology is adopted by the imaging system. A built-in ISP of a CPU is utilized for image processing, so the hardware cost of the collector end is greatly reduced; and a differential signal is adopted, so the interference resistance to an industrial environment is stronger; the product efficiency is improved, and the power consumption is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of barcode acquisition and imaging, in particular to a barcode automatic recognition acquisition imaging system and method. Background technique [0002] The application of barcode automatic identification technology is the basis of modern management today, and it plays an indispensable role in logistics management, POS system, medical system, e-commerce, supply chain management and even today's popular mobile Internet technology. In recent decades, it has developed rapidly around the world. With the explosive growth of China's mobile Internet in recent years, the popularity of barcode recognition has also been quickly accepted by people. [0003] At present, in the field of barcode automatic identification collar collectors, there are mainly Zebra, Honeywell, Datalogic in the world, and several domestic manufacturers such as Xindalu and Mingde. As the core equipment of barcode automatic identification tech...

Problems solved by technology

As the core equipment of barcode automatic identification technology, the collector has always had the problem of high unit price. For example, a PDA with a scanner, the two-dimensional scanner accounts for 30% or more of the product cost

At present, general-purpose scanners implement barcode analysis by integrating a microprocessor inside, which increases product cost while improving product versatility.
