The machine vision technology of the future is destined to steer business

The quickly developing machine vision technology can be utilised comprehensively in various industries. Extremely accurate machine vision provides real-time information about production and products, such as shapes, colours and surface structure. Machine vision-based imaging effectively produces digital information usable for the purposes of measurement, production control and analysis, quality control, and optimisation, for example.

Machine vision solutions are full-fledged production process optimisers and controllers. Automation and production control systems are capable of utilising the data collected more efficiently than before, as artificial intelligence algorithms extract indicators optimising and predicting operations from enormous amounts of data.

Examples of machine vision application in industry:


Web monitoring and control, for example, at paper or steel production lines

Production quality assurance, component handling and positioning

Optical dimension measurements, reading of codes and markings in production

Why machine vision? Speed brings growth, quality reduces waste

Machine vision solutions bring efficiency to production and automation, since they can be utilised in a versatile manner not only in quality and production control, but also in the development and optimisation of production processes. Machine vision is tireless and therefore fast, and accuracy minimises waste. At its best, an intelligent machine vision solution functions as an integral part of production control and its development, even completely independently, allowing production personnel to focus on tasks that are more important, such as development of production operations. 

Machine vision is at its best in case of large production volumes and tight quality standards. Machine vision supports production growth and reduces material waste.

Success story

CP Kelco

“Previously, we analyzed the quality of CMC by visual inspection methods. The analysis equipment provides results that are more reliable than the human eye helping us develop the product and its production.”

– Simo Mäntymaa, Quality Manager

Earlier, all inspections were carried out visually. Each cartridge was inspected for cracks – dimensions were randomly checked. Human errors are always possible in tasks that require perseverance and attention. In automated inspection, this risk is avoided. The work can also be performed faster with the help of Pinja’s machine vision solution.
