1 minute to understand barcode/QR code recognition and detection

Barcode/QR code has the characteristics of large storage capacity, strong confidentiality, high traceability, strong resistance to damage, and low cost. It has penetrated into every corner of our lives, and has spawned with barcode/QR code as the connecting carrier. New ecological chain in more fields. In many fields such as industrial automation, logistics, food, wholesale, and medical supplies, barcodes/two-dimensional codes play a vital role. Barcodes/two-dimensional codes (QR codes, DataMatrix codes, MaxiCode codes, Aztec codes, etc.) are recognized As a result, detection has received more and more attention from automated production and application companies. For the two-dimensional code recognition technology, traditional code readers are not only susceptible to environmental influences during the recognition process, but also have limitations for reading multiple codes at the same time. This requires high-resolution industrial cameras and machine vision technology for image preprocessing, decoding, and error correction. In the product production process, the VisionBank intelligent vision system can be used for multi-threaded tracking and recognition of product barcodes/two-dimensional codes. The intelligent vision system performs detection and comparison with the bar code information identified by the bar code according to the length of the bar code or the content of the bar code, and gives a judgment. The two-dimensional code is detected with a size of 2mm, and the VisionBank intelligent vision system uses a lens with a larger magnification, which can be easily identified. For some special scenes, multiple small-size QR codes need to be recognized at the same time in a larger field of view. The MV-EM series high-speed industrial cameras and the flexible VisionBank intelligent vision system can solve them perfectly.
