Optical inspection system OCR

Manufacturers using traceability systems print some information on packaging to inform the end-user, comply with legal regulations, and recall and product tracking operations. Identification of this information printed on product packaging with OCR (Optical Character Recognition) and verification with OCV (Optical Character Verification) is vital for the traceable supply chain. Incorrect or incomplete information on packaging will undermine brand safety, as well as cause companies to suffer significant financial losses. As VISIOTT TPS, we use OCR / OCV technology at our stations that offer many different solutions within the traceable supply chain to avoid this situation. Although OCR and OCV are usually similar, there is a significant difference between them. OCR technology compares the model of the printed alphanumeric character with the pattern of each character in the database. OCV, on the other hand, receives preliminary information about what the specific alphanumeric model is and checks whether the current character is complete. There are a number of special rules for OCR/OCV technologies. A typical character should cover an area in a 20-25 px * 20-25 px layout, while the space between characters should be two pixels.
