Braille Printing Plates

Posted in Dark Field Illumination, Featured, Inspection, Object Location, OCR (Optical Character Recognition), Other

The Challenge: To be able to detect and identify the braille characters marked on the surface of a metal plate. Our Solution: The braille alphabet was pre-programmed into the database for reference once the characters were identified with the machine vision system and lighting solution. Using a Dark Field Lighting Technique we were able to identify the braille characters on the surface of the product. The light does not fall directly onto the objective and the majority of the region of interest is dark, while the affected areas on the surface, the braille characters, appear bright. Once the impressions were identified and segmented, they were then referenced to the database and the string of characters were identified.

Barcode Reading

Posted in 1D Barcode Reading, Featured, Food & Beverage, Inspection, OCR (Optical Character Recognition), Part Identification

The Challenge: A printer generates a product label ready for application onto a product. Prior to application, each label needs to be inspected to ensure that the print quality and the information  printed is of suitable quality and correct. The labels index at a rate of 2 per second. Our Solution: A high resolution camera system was employed to read the label information using OCR (optical character recognition) and also to grade the barcode to the ANSI standard. Labels with either incorrect, partially missing data or poorly graded codes are marked by an inkjet marker and removed from the line prior to...

Food Label Reading

Posted in 1D Barcode Reading, Featured, Food & Beverage, Inspection, OCR (Optical Character Recognition), Part Identification, Uncategorized

  The Challenge: Product information is printed directly onto the outer case of food products as they travel down a conveyor at a speed of 10m/min. The information contains a barcode, the product’s weight, best before dates and the price. All of the information needs to be read and checked against the database and weight sensors situated on the line. Information on the product type is contained within the code, which also needs to be checked. All data needs to be logged in a database located on the network for future traceability. Our Solution: A complete turnkey solution was provided to the customer to be able to read, verify and record the information contained in the printed information....

Optical Character Recognition

Posted in Automotive, Featured, Inspection, OCR (Optical Character Recognition)

The Challenge: The customer wanted to correctly identify 15 alphanumeric characters which had been laser marked onto the surface of an electrical component. The quality of the part marking was poor and the marked surface uneven in nature. Our Solution: A self-contained Vision Camera was used to correctly identified the characters and relayed the information to a PLC for verification of correct codes. The powerful in-built OCR algorithims were able to reliably read the codes even under these challenging conditions. Read rate...

Pack Reading

Posted in 2D Datamatrix Reading, Direct Bright Field Illumination, Featured, Food & Beverage, Inspection, Lighting, OCR (Optical Character Recognition), Packaging, Uncategorized

The Challenge: Each pack has a label printed and applied to it and the 2D barcode and expiry date of each code needs to be read as the pack passes down a conveyor at a speed of 8m/min. The 2D code needs to be checked to ensure it contains the expiry date that is also printed on the pack. Information on the production / batch run is also contained within the code, this needs to be logged in a database located on the network for future trace ability. Our Solution: A complete turnkey solution was provided to the customer to be able to read, verify and record the information contained in each label....
