Barcode Tool

Sapera Processing offers two different barcode reading algorithms:

  • Quick Barcode is the preferred tool as it allows very high speed reading while being tolerant to noise, occlusion and geometrical distortions. 
  • However in cases of very highly degraded conditions Standard Barcode might be a good alternative to Quick Barcode. Standard Barcode provides more flexibility in adjusting parameters as well as providing the ability to create golden models for an increased robustness.

As part of the barcode tool Sapera Processing also offers Print Quality Grading. Grading is used to verify the quality of 1D and 2D marks.

Quick Barcode

  • Quickly and accurately reads printed, stamped or etched 1D/2D codes
  • Reliably reads Data Matrix and QR codes with damaged or missing finder patterns
  • Reads poorly printed, low contrast, noisy, warped, and damaged barcodes
  • Decodes multiple barcodes in the same image ROI
  • Two licensing options:
    • Quick Barcode decodes the majority of codes.
    • Quick Barcode DPM offers greater robustness for decoding marks etched or dot peened on plastic or metallic surfaces

Standard Barcode

  • Supports 1-D and 2-D industry standards (includes the majority of standards supported by Quick Barcode).
  • High tolerance for noisy and poorly illuminated images
  • Asian native language and Unicode output

  • Supports model training on Data Matrix for increased robustness highly damaged images
  • Two licensing options:
    • Standard Barcode supports a wide variety of codes and options, and does not require training
    • Advanced Barcode offers the ability to train a Data Matrix model for increasing robustness while supporting the same codes and options as Standard Barcode.

Print Quality Grading

  • Use in combination with Quick Barcode or Standard Barcode
  • Includes the following standards:
    • ISO/IEC 15416 (Barcode print quality test specification - linear symbols)
    • ISO/IEC 15415 (Barcode symbol print quality test specification - Two-dimensional symbols)
    • ISO/IEC 16022 (Data matrix barcode symbology specification)
