DataMatrix Codes, like QR-Codes, are used in logistics to identify and track products during the manufacturing process. A CMOS camera is used to read the barcode, illuminated by a LED flash. The DSP system corrects optical distortions, normalizes and decodes the barcode. A network interface transmits the data to the inventory management and production control system. A HTTP server running on the DSP system provides configuration and adaptation.
Printing Quality Control
Cost-efficient CMOS image sensors can be used for various applications, and allow a direct connection to a DSP system. The DSP corrects image distortions caused by the optical system and the sensor. The quality parameters of the print products are evaluated by inspection of the print control strips. The results are used for quality control and automated process calibration.
