Machine vision systems

 

The vision systems are composed of one or more devices, which deal with the acquisition of data (images) and a device capable of receiving and analyzing these data, generally a PC, using appropriately designed algorithms.

The heart of the artificial vision system is therefore made up of one or more cameras and appropriately chosen light sources, to which is added the intelligence of the system, represented by the vision algorithms and the management software, indispensable for being able to communicate with other systems but also with the operators.

The vision systems can in fact be integrated within a production cycle, or be installed off-line as stand-alone control machines.

Design flexibility

Design flexibility

The design of vision systems is extremely flexible, as the choice of devices is strictly linked to production needs and analysis requirements. There are numerous possibilities of choise about acquisition and lighting devices.

Depending on the type of analysis, the acquisition can in fact be carried out with multiple instruments. A first classification on the type of device is given by the frequency band of the light on which the image is to be captured.

Most vision systems operate in the range of visible electromagnetic radiation (390-750nm). However, there are many areas such as agri-food, medical, environmental monitoring and safety, where the devices are able to see in ultraviolet and infrared. There are also vision systems that are able to "see" in different bands of the spectrum: ie multispectral and hyper-spectral technologies, mainly used in environmental and food fields.
 

Advantages of a vision system

Advantages of a vision system

The vision systems are therefore designed and created with the aim of performing analysis on digitally acquired images and guarantee important advantages:

  1. vision systems allow to perform objective analyzes in conditions and speeds unthinkable for the human eye: research and measurement of centesimal defects on tens of pieces per second. They also generate an increase in productivity.
  2. vision systems operate without contact with the object under examination: this is often necessary and required, especially in biomedical areas, as it eliminates the possibility of inadvertently introducing damage and / or contamination.
  3. vision systems guarantee an even broader view of the production process, no longer limited to a single product.
Vision systems and Industry 4.0

Vision systems and Industry 4.0

The vision system is therefore a powerful medium that is becoming increasingly essential within companies. Ensures precision, reliability and stability; thanks to the high speeds that can be achieved by automating the processes, productivity increases.

The production is also more controlled: the analysis performed is objective and entirely traced and documented. The type of data that can be collected is very wide and guarantees an even broader view of the process, and no longer limited to the single product.

These features make vision systems perfectly compatible with the requirements of Industry 4.0: they are not simple good / waste selectors but are systems that can communicate and interact with other devices, as well as being an invaluable source of data, from which to draw essential information in order to identify the critical parts of a production process. Finally, they allow intercepting any drifts before they can lead to the production of defective parts or damage to machinery.
 

Application of vision systems

Application of vision systems

Through the vision systems the possible controls are various: they can concern the dimensional and morphological control of the pieces, but the controls dedicated to the reading of codes (alphanumeric writing, barcode, QR Code and similar) and pattern recognition are also very important.

Another application concerns the search for manufacturing defects: each type of production must comply with often stringent quality requirements. The defects can be not only aesthetic, but also functional and structural and as such crucial for the finished product or the final product / system for which it is intended.
 

Why choose IMAGO Vision Systems

Vision systems have undeniable advantages for all industrial sectors. To these requirements inherent in the system, we at IMAGO add our Vision, which derives from the high competence of the entire company team and from the experience gained in the most diverse areas. Working closely with different production realities (from automotive to biomedical field, from wire drawing to food or pharmaceutical fields) assures us a really broad vision, a well-tested experience and an always concrete approach to the various problems.

It follows that our vision systems are designed and built thinking about who will use them, by identifying ourselves with the operator who works on the machine, but also in the manager or in the maintenance technician. In fact, we know that usability and immediacy of use are another important key to facilitate the adoption of such a powerful tool.

Our vision systems are also constantly updated based on customer requests, market trends and new technologies, as introduced by our Research and Development department.
