Code recognition / Code control

Datamatrix Code Recognition

Our systems are suitable for reading needled, lasered and printed codes on a wide variety of substrates.
Even difficult codes and large reading distances are no problem. A module for code evaluation in accordance with DIN completes the range.

Features

  • Omnidirectional detection
  • Automatic code type recognition
  • Automatic correction of perspective distortion, damage to the code and changes in lighting
  • Multi-reader function for reading multiple codes in one image
  • Code content check via comparison code
  • Code rotation check
  • Code position angle can be selected

Code evaluation Datamatrix

The Code Surveyor 2D is a module for the objective evaluation of data matrix codes in accordance with DIN ISO15415. This
allows the code quality to be monitored even during ongoing production and any deterioration in the print quality of inkjet printers and other target deviations can be reliably recognised.

Quality report

Items to test and evaluate:

. Axial distortion
. Screen unevenness
. Symbol contrast
. Unused error correction
. Fixed pattern damage
. Modulation
. Decoding
. Quality report

Barcode recognition

Our systems are suitable for reading needled, lasered and printed codes on a wide variety of carrier materials. Even difficult codes and large reading distances are no problem. A module for code evaluation in accordance with DIN completes the range.

Features

  • Omnidirectional detection
  • Automatic code type detection
  • Automatic correction of perspective distortion, code damage and lighting changes
  • Multi-reader function for reading multiple codes in one image
  • Code content check via comparison code
  • Code rotation check
  • Code position angle can be selected

Code evaluation barcode

The Code Surveyor 1D is a module for the objective evaluation of barcodes in
accordance with DIN ISO15416/ANSI X3.182-1990/ANSI/UCC5-1995. This allows the
code quality to be monitored even during ongoing production and any deteriorating
print quality in inkjet printers and other target deviations can be reliably recognised.

Items tested and evaluated:

  • Decoding
  • Symbol contrast
  • Minimum reflection
  • Global threshold
  • Minimum edge contrast
  • Modulation
  • Defects
  • Decodability
