Learn more about machine vision! In our knowledge base we are explaining key technical terms about image processing. We give you an overview to topics like 3D machine vision or the established standards like CameraLink, GigE Vision or GenICam.
A 'Vision System' is defined as a prebuilt solution that is ready to configure and deploy, containing the sensor, processor and software. While generally used to automate manufacturing and secure product quality, the use of vision systems in non-industrial applications such as medical, traffic, sports or entertainment is becoming common.
Chemical Colour Imaging (CCI) makes complex hyperspectral data on a molecular level usable for machine vision. Hyperspectral imaging systems from STEMMER IMAGING CVS HyperInspect based on a generic, intuitive configurable data processing platform developed by Perception Park make the scientific methods of hyperspectral analysis accessible for everyone and open up new application areas.
Hyperspectral imaging visualises the molecular structure of materials by different colouring in the resulting images. This unique chemical fingerprint enables easy and reliable identification of identical or different looking objects. It also works the other way round: It is possible to detect identical material properties of different looking objects.
Our infographic gives you a short introduction into the new technology:
The integration of industrial vision systems into production processes in order to enhance quality can often be challenging. This typically requires the services of a specialist vision systems integrator. The installation set up may be complex, or a complete turnkey solution including product reconciliation, rejection and handling may be necessary. STEMMER IMAGING can partner with systems integrators to provide an unprecedented level of support ranging from vision component supply to the development of a complete vision solution ready for integration into the manufacturing process.
Panel design and manufacture has become a lot more complex with modern day cars, the sheets undergo greater stresses during formation and the surface is made up of many more layers with a lot more choice in colours. As these increase, the need for automated inspection does as well. In this article we cover some of the defects encountered and a few of the ways they can be inspected using machine vision.
Machine vision is used for a diverse range of tasks in a wide range of markets. This diversity of application requirements drives the need for a wide range of vision systems to achieve a solution that is not only cost effective but also delivers the required features. This section outlines the basic choices in terms of hardware and software at a systems level to enable this optimum solution to be defined. Further information on the software tools can be found in the software section.
Many system integrators and advanced vision system developers value
the flexibility and openness of PC vision systems and develop their
individual software solutions using imaging libraries and high level
programming languages. More information about this approach is to
be found in the software section.
In most cases the vision system needs to be integrated with the
production system or machines programmable logic controller (PLC).
Inspection results should be directly transferred to the control system
to enable immediate reaction.
As the complexity of inspection applications can vary considerably it is important that the chosen solution fits the project requirements. A high level of flexibility will allow easy adaptations for new tasks that might occur later. Considering possible future needs should form part of the specification phase.
