AI-based OCR capabilities available on vision system

24 January 2023

Cognex Corporation has expanded the capabilities of its In-Sight 2800 vision system to include optical character recognition (OCR).

The new ViDi EL Read tool can decipher human-readable characters on reflective, low-contrast and non-flat surfaces with ease.

OCR applications can be time-consuming to set up, requiring hours of programming by highly trained engineers, preventing many companies from automating this type of inspection. Using the ViDi EL Read tool, models are set up and deployed directly on the device in minutes with as few as 10 sample images. The accuracy of the results is measured by a confidence score that is displayed below each of the trained characters offering real-time, visual feedback and reassurance of reliable traceability across the supply chain.

The solution can help food and beverage producers to easily read expiration dates, even on curved surfaces, to verify freshness and prevent consumer recalls. Medical device and pharmaceutical companies can verify dates and lot codes to ensure vaccine efficacy and compliance with medical standards, while electric vehicle manufacturers can quickly locate and read the alphanumeric text laser etched on the bottom sides of EV batteries to improve traceability, and logistics facilities can decipher codes and text on a variety of package types to ensure proper routing and prevent rework.
