The LMI Gocator range of 3D smart cameras available from Stemmer Imaging has been enhanced with new measurement capabilities, scripting and PLC interoperation for use across a variety of manufacturing industries.

These new facilities are also available for existing Gocator users through a free firmware download (V3.3).

New tools include gap and flush measurement, groove measurement and extended whole-part measurement. A megapixel-resolution version is also now available.

According to Stemmer, integrating Gocator sensors into PLC-controlled factories is now much easier and requires no software programming. Gocators are certified to communicate with a range of PLCs, including Allen-Bradley and Omron, via the industry-standard Ethernet/IP protocol.

Key enhancements

Gap and flush measurement tool

  • This allows Gocator sensors to perform precise inline non-contact gap and flush inspection by measuring the distance between two sharp- or curved-edge panels.
  • This toolset allows tolerances to be set and measurements and inspection decisions to be made without costly external inspection units.
  • The tool is suitable for inspecting the fit and finish of assembled panels in automotive production.

Groove measurement tool

  • This tool measures the width and bottom of V- and U-shape grooves and enables users to accurately set pass/fail conditions and inspection decisions based on these measurements.
  • It is suitable for applications where grooves are essential to a product’s performance, such as tyres, plastic container lids or tongue and groove materials.

Whole-part measurement capability

  • This has been further enhanced with the addition of a rotated box measurement tool.
  • The whole-part measurement process is achieved by automatically detecting the start and end point of a single component (or multiple components) travelling along a conveyor.
  • The rotated box tool makes it possible to accurately measure an object in whole-part mode, even if it is not perpendicular to the laser line during scanning; this allows the measurement of an object’s true width and height by accounting for its angle of rotation.
  • The rotated box tool is important for applications such as packaging inspection, where it is likely the items will not be precisely lined up as they come down the line.

Script measurement tool

  • A new extension to this tool allows users to carry intermediate results from one frame to another to calculate statistics (such as averages) or to accumulate results.
  • For applications such as bread cutting or web scanning, this tool is claimed to make it easy to calculate accumulated measurements (such as volume) from each scanned cross section.

Occlusion prevention tool

  • This allows every angle of intricate surfaces to be ‘viewed’ without fear of occlusions.
  • Any occlusions are eliminated by merging data from the main sensor and buddy sensor to extract data from the best view of the target’s surface in the X and Y directions.

STEMMER IMAGING is Europe’s largest imaging technology provider with headquarters in Germany and subsidiaries in the United Kingdom, France and Switzerland.

Image processing or Machine Vision is used in many different application areas – such as industrial automation, medical imaging, security and traffic technology – as a powerful and cost effective way of implementing automatic quality assurance. Even at high speeds and with stringent accuracy requirements, image processing allows 100% monitoring and thus strengthens the competitive edge of those companies using it.

STEMMER IMAGING customers have access to a wide variety of imaging products from the worlds leading manufacturers. These manufacturers represent the cutting edge of vision technology which is something that is unique in Europe. STEMMER IMAGING are the developers of the world’s leading image processing software platform, Common Vision Blox, and as a manufacturer of customer-specific products, we have a full range of in-house expertise to draw on, allowing us to supply the best possible service to our customers when choosing an imaging solution. STEMMER IMAGING does not produce turn-key solutions – instead, using our close partnerships with a large number of experienced system integrators, we can provide expert technical know-how for the planning, integration and realisation of complete solutions.
