Wenglor has introduced the tiny OCR Reader, which automatically recognises characters.
Optical character recognition (OCR) involves automatic character reading of a printed master.
Wenglor has introduced the tiny OCR Reader, which automatically recognises characters.
The actual OCR process is preceded by a structure analysis.
First, text blocks are separated from graphic elements and the line structure is detected and individual characters are finally isolated.
Work steps executed by OCR include image recording, AOI detection (area of interest), segmentation, character detection and dictionary comparison.
Wenglor's OCR Reader deciphers all characters and numbers in all languages.
Logos, symbol combinations, image fragments and print marks are memorised after just one training process.
Characters can be printed, needled, pierced or spotted.
Reading, comparison and go/no-go evaluation of characters and symbols are simple and reliable.
Up to four different objects per image (with 25 characters each) can be read in, compared and read out, which means the user only needs one OCR Reader for four different reading tasks within the same range of vision.
Up to 20 projects and 20 character sets can be stored to the sensor to this end.
The OCR Reader with auto-focus adapts quickly to each new reading task.
Even if products are transported at high conveyor speeds, Wenglor's OCR Reader records up to 100 sharp images per second.
The OCR Reader can read up to 100 characters per scan.
Data is read out via the RS 232 port after image evaluation.
Expiry dates and serial numbers are read out quickly and reliably.
The OCR Reader can be quickly integrated into a production system via the integrated USB 2.0 port.
The Wenglor OCR Reader is controlled by a multilingual Windows-based software with a clear-cut user interface: it simply needs to be connected to a PC via the USB 2.0 port.
The intuitive user interface simplifies teaching in characters.
The auto-focus function can also be controlled with the software.
The user interface is touch-screen compatible if required by the customer.
The Inoxsens protective housings used for the OCR Reader are made of high-quality stainless steel (V4A 1.4404, 316L).
Accessories have been developed to meet the demands of the pharmaceutical, food and beverage and packaging industries.
The OCR Reader is available with red, white or infrared light.
This assures ideal basic illumination for each reading task.
Wenglor also offers a range of external illumination solutions.
Wenglor spot lights, ring illuminators and flood lights are available in white, red, blue, green, UV and infrared.
