Read & Verify Codes & Labels in Industrial Manufacturing Environments

Ensure readability across the supply chain

With senswork's vision systems, labels and barcodes can be reliably detected, read and checked for accuracy. Even curved or reflective surfaces are no problem for our camera systems thanks to modern AI technology. We also offer the senswork ZPL Inspector, which automatically generates and executes inspection programs based on ZPL printer files.

AI for Label Inspection

Where traditional image processing tools reach their limits, Deep Learning shows its strengths in OCR applications

  • Reading on an Inhomogeneous Background

    Segmentation has always been the biggest challenge with previous OCR systems. Fluctuating brightness or variable backgrounds could quickly lead to false reads. AI systems, on the other hand, are able to segment and classify characters even on inhomogeneous backgrounds. This significantly increases reliability and robustness in many industries.

  • Weak Contrast

    Similar to inhomogeneous backgrounds, weak contrast can also quickly bring classic font reading systems to their knees. Here, too, Deep Learning shows its strengths. An AI system can even read raised lettering on rough surfaces such as cast aluminum robustly and reliably.

  • Varying Characters

    AI-based reading tools are adaptable and can easily handle different fonts, sizes, and layouts without the need for complex manual adjustments. Especially in the case of stamped or embossed fonts and inkjet printing (e.g. sell-by dates on food packaging), the character representation can vary considerably while the text remains legible to the human eye. This is where the strengths of AI come into play.

  • Learning New Fonts or Font Sizes

    Thanks to its training, an AI system has a diverse collection of fonts that allows it to effortlessly handle a wide range of characters, regardless of their size, style, or stroke width, without prior training. If necessary, additional characters can be integrated into the training to further increase the robustness of the system.

Detect Defects in a Printed Image at the Highest Level

We detect reliably:

 

  • Print offset
  • Print position of individual print elements
  • Incorrectly printed characters
  • Incorrectly printed characters
  • Blurred characters
  • Graphic symbols for completeness
  • Frames and lines for completeness and possible interruption
  • Barcodes: Completeness, broken lines, contrast, conformity to standards
  • Datamatrix codes: AIM-DPM, ISO 15415
  • Background for contamination
  • and many others.

Fully automated ZPL-based print inspection - is it possible?

Yes, thanks to senswork ZPL Inspector!

senswork's ZPL-Inspector enables direct interpretation of ZPL (Zebra Printer Language) print jobs and automatic generation of inspection programs. This means that our ZPL-Inspector camera solution automatically adapts to the print layout without having to change the inspection program. The contents of the ZPL printer file are read and interpreted, and an appropriate inspection program is generated - fully automatically and without user intervention.

Reading 1D and 2D Barcodes

Read and evaluate the quality of directly marked and printed codes

For the identification and traceability of products and components, codes are applied to them using various methods, such as laser marking, needling or printing.

 

To ensure the quality and readability of barcodes, there are several standards such as AIM/DPM or ISO/IEC. These define partly different quality characteristics for the evaluation of codes. AIM/DPM is aimed at directly marked barcodes, while ISO/IEC 15415 deals with printed 2D codes.

Benefits - that's why with senswork

The planning of OCR and OCV systems requires extreme care. In addition to the correct camera resolution, suitable illumination of the reading area is crucial. In particular, the choice of illumination wavelength, whether visible light or infrared, can have a significant impact on background suppression. Different printing methods also require specific reading instruments. While conventional methods may be sufficient in some cases, we increasingly recommend the use of our AI-based tools for reliable inspection results.

 You can rely on us! As a competent partner, we will make your OCR or OCV project a success.
