Vision system with OCR08 May 2009
Optical Character Recognition (OCR) is a popular inspection task for industrial Machine Vision systems, e.g. for presence or content checking of serial numbers, use-best-before-dates, or component markings, use-best-before-dates, or component markings. With the new PV530, the successful and industrially proven, high-speed Imagechecker PV500 has been expanded to include OCR.
Here are a few of the impressive features our OCR algorithm makes possible:
Powerful segmentation (separation) of characters, even if single letters touch each other
Efficient teach-in of fonts in up to 5 dictionaries
Up to three sub-fonts for each font
Multidirectional recognition as fast as 5ms/character
Reading of mirrored strings
Sophisticated detection algorithm - also for dot-matrix prints
Filter function enables reading strings on challenging backgrounds
Calendar function for the automatic extrapolation of expiration dates
In addition, PV530 offers all functions of the PV500. Hence, besides optical character recognition, the system allows you to solve applications in the fields of measurement, part recognition, position detection, sorting, etc., quickly and reliably.
