The LMI Gocator 3D smart camera — available from Stemmer Imaging — can be mounted on a robot arm to provide a rapid and accurate way of making gap and flush measurements on automotive panels.

These measurements are said to enable the correction and error proofing of any build problem; the reduction of unexpected cost in repairing misassembled panels; the reduction of waste from discarding damaged panels due to fit problems; and even the rejection of the vehicle if the panels are badly misaligned.

The Gocator is mounted on a robot that is used to position the sensor so that two panels are in view of the sensor. Once the sensor is positioned, the robot will initiate a start signal to the sensor to begin measuring.

The part of the laser line that falls on the flat part of the panel forms a natural reference for the measurements. The sensor will then perform the gap and flush measurement and on completion signal the robot with the inspection results.

Key features and benefits

  • Incorporating an integral laser line source, optics and camera, the Gocator camera enables the simultaneous measurement of both the gap and the flush at very high accuracy.
  • Gocator features a host of built-in measurement tools, which are configured through a standard web browser; this allows the entire measurement sequence to be set up quickly and efficiently without any custom software programming.
  • Gocator is supplied pre-calibrated and ready to use straight from the box.
  • The Gocator camera supports several industrial PLC protocols to control the sensor and to collect measurement results.
  • An open-source software development kit (SDK) is available for engineers who want to do their own programming.

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.
