Digital and Information Technologies in Metrology 4.0

Industry 4.0, on which many different studies have already been written, brings with it a completely different outlook, especially in IT. Cyber-physical systems, the Internet of Things, networks and cloud-based big data, artificial intelligence, and robotics are essential elements that have also found their way into Metrology 4.0, sometimes called Metrology of the Future. In the paper, measurement technologies for Metrology 4.0 were presented. They belong to coordinate measurement techniques in different scales: macro, micro, and meso. Optical scanning and computed tomography were discussed, focusing on achievable big data. From an IT point of view, the use of artificial intelligence was shown. The possibility of using augmented and virtual reality was also depicted with a short note on cybersecurity. Finally, some ideas regarding Metrology for the Future were briefly presented. It will probably be more oriented to man and use the planet’s natural resources more efficiently. Systems will be based on objects working together, with the definition of connections using the idea of blockchain. And as the data overgrows, data management systems and applications will appear, allowing the user to select the most relevant data.
