In-Sight Vision Tools

The industry-leading Cognex vision tool library provides reliable, repeatable performance in even the most challenging vision applications.

Powerful Location Tools

PatMax Pattern Matching

If a vision system can’t repeatedly locate parts because of wide variations in part orientation, size and appearance, then vision inspection yield and reliability will be significantly reduced.

These variations include:

  • Part contrast
  • Multiple parts
  • Changes in lighting
  • Image focus
  • Degraded appearance
  • Partially-hidden parts

PatMax®, the industry’s performance standard for part and feature location software, utilizes advanced geometric pattern matching technology to reliably and accurately locate parts. Even under the above conditions, this tool can significantly reduce or eliminate fixturing requirements and cost. For locating parts or features, PatMax provides the maximum vision inspection yield and reliability available in a vision system. PatMax is optionally available on all
general-purpose In-Sight vision systems.

Breakthrough Code Reading
IDMax

Standard on most In-Sight models is IDMax®, breakthrough code-reading software based on the patented Cognex PatMax technology, through 1DMax™ and 2DMax™ algorithms. IDMax can read 1D code symbologies such as UPC, PDF, stacked and postal codes, 2D code symbologies such as Data Matrix and QR, or a mix of barcode and 2D codes simultaneously.

1DMax is a best-in-class 1D barcode-reading tool optimized for omnidirectional barcode reading and can handle extreme variations in contrast, blur, damage, voids, specularity, resolution, quiet zone violations and perspective distortion.

1DMax code-reading technology

2DMax is optimized for reading QR codes and handles a wide range of degradations to 2D Data Matrix code appearance that result from dramatic degradations in Direct Part Marking (DPM) code quality due to differences in material types and surfaces.  2D Data Matrix code reading in DPM applications is an increasingly important part of manufacturing processes. An unreadable code may stop production, and can result in the part not being processed correctly.

Advanced OCR / OCV

Optical Character Recognition is essential for numerous applications in the automotive, food & beverage, consumer products, pharmaceutical, electronic, and postal markets for traceability and product quality assurance. The advanced OCR / OCV tool in In-Sight Explorer makes text training easy with pre-trained fonts and offers a high level of confidence for character reading and verification using a new Accuracy Mode. Algorithm improvements now allow for more degraded and poor contract character on noise backgrounds.
