Combining smart cameras with deep learning software uses optical character recognition (OCR) to decode damaged barcodes. Thanks to the pre-trained font library of deep learning, the deep learning barcode reading tool in the software is ready to use out of the box, greatly shortening the development time. Users only need to define the target detection area and set the character size. When introducing new characters, you don't need to have visual expertise, and you can also retrain this robust tool to read application-specific barcodes that traditional OCR tools can't decode.
