Machine Vision

Machine Vision solutions are designed to control visual quality of products, using all available technology for obtaining an image.

About the solutions

A typical area we primarily focus on is visual quality control in production. We create solutions based on customer requirements, using all available technology for obtaining an image (area and line scan cameras, nanocameras or multispectral sensors). Our solutions are not hardware-dependent; therefore we can cover all customer requirements without restrictions if there's a technology that allows it.

We are able to introduce a functional prototype to the customer in a very short time, proving the system's capability to meet the demands placed upon it. A significant part of the delivered solutions is the design and production of custom lighting systems, development of special optical systems and lenses, and other components necessary for this application.

Machine Vision systems enable to:

  • Detect surface and other visible defects
  • Measure and inspect shapes
  • Measure dimensions
  • Check the presence of assembly elements
  • Recognize patterns
  • Read alpha-numeric characters (OCR), Barcode, MatrixCode


DAVIS - A Comprehensive Camera System


DAVIS is a camera system focused on automatic quality control in challenging and high-speed production processes and technologies. Besides product sorting DAVIS analyses the causes of defects and the creation of tools for their elimination.

Surface Inspection


Detection of surface defects, such as porosity, handling marks, scratches, cracks etc., is one of the most demanding types of visual inspections. We use special optical and lighting systems designed to detect very small surface defects (tens of microns) in high speed and high inspection resolution. Some surface defects can be spotted just from the changing relief. Here, direct or hybrid 3D technology is used (laser scanning, collimated illumination, and Shape-from-Shading).



The Optoband system provides a full 100% inspection of pre-assembled bearing rings and flanges to detect any appearance and functional defects in the running surface and other functional surfaces of parts. Both sides of product are gradually inspected at a top speed of 460 parts per minute. The measurements of appearance and fine height defects, part flatness and an inspection of vertical molded parts, giving rise to various cracks and other mechanical damage, can be integrated to the system as required. The parts are automatically sorted into three groups.

DAVIS for Hygiene

DAVIS is designed to inspect the production of female sanitary towels. It is a fully automated inspection system of the production machine with production speeds up to 35 towels per second. The sanitary towels are inspected at four locations along the production line using different technologies (UV camera, IR camera, multispectral line camera, etc.). Control data from these stations are synchronized from information about machine speed in the production control system. The inspection results in the controlled separation of nonconforming products, a large number of statistics, and reports on quality parameters. The system has a highly sophisticated user interface. About 50 product parameters are checked simultaneously.

Inspection of the Plastic Caps of Airbag Detonators

The system is designed to check surface and internal material errors on the detonator caps of the pyrotechnic charges in airbags. The cap is made of transparent plastic and the system checks whether there are any internal or surface errors that may impair the component. The cap operates the explosion of a pyrotechnic charge and belongs among the most important components.

Final Inspection of Assembled Electric Drives

This is an inspection of electric drive production after final operations. The drive is scanned by several cameras, monitoring the presence of components, their dimensions, and placement (for example, the presence and dimensions of gaskets mats, belt drives, overall drive dimensions, and assembling components, such as meshes, etc.).

BTF Camera

The system is designed to operate a vacuum compressor for coating furniture parts (such as a kitchen hatch) with a plastic foil. The camera system recognizes the shape and location of components placed on the compressor and subsequently configures the nut of pneumatic pins that must lift the individual parts during the vacuum foil coating.

Surface Inspection of Large Format Materials

The system is designed for precise surface inspection of large format semi-products. The system uses special line cameras and linear lighting. It's capable of recognizing defects at a high resolution, such as:

  • Porous areas, large chips, cracks
  • Dust, oil, and other stains
  • Change in the surface color or gloss
  • The entire system can be used for sorting boards into qualitative groups, assessing the statistics of individual defect occurrences, signaling an increased occurrence of a certain error (alarm state), visualizing defects, and many other functions.

Mold (Kokila) System

This system is deployed in foundries where casting process runs in semi-permanent molds. If there is any impurity on a mold's contact surface, the mold will not close completely, causing the molten metal to subsequently leak. The Mold (Kokila) System monitors whether the mold was properly closed before casting. This condition must be met for the system to allow the machine to cast the metal batch into the mold. The system is also specific as it runs in very dusty and heat-demanding environments.

Control of Thrust Bearing Components

The system inspects both sides of around 360 thrust bearing and gearbox rings per minute at a high cadence. The rings require a high surface quality and strict dimensional tolerances. They are inspected for size and surface quality.

LSA 2000+

The LSA 2000+ System is designed for the geometrical and aesthetic sorting and inspection of wooden slats for the creation of the surface layer of large-format parquets. The main system inspection parameters are:

  • A 3D camera for the inspection of surface defects (fissures, grindings, grooves, large cracks...)
  • Measuring dimensions (length, width, thickness, perpendicularity of the cut...)
  • Sorting into qualitative groups
  • Speed up to 330 slats per minute

Inspection of Inclusions in an Extruded Plastic Belt

This system checks debris in the extruded plastic belt for the production of plastic foils. The thickness of the inspected foil is 0.25 - 0.068 mm, and the size of the smallest detected defect is 0.2 mm at a material speed of 55m/min.
